PAINT DRAIN CLOSURE, ATTACHMENT TOOL AND METHOD

PAINT DRAIN CLOSURE, ATTACHMENT TOOL, AND METHOD Abstract of the Disclosure An improved closure for sealing the paint drain holes of a vehicle body, and a tool and method of use therefor, are disclosed. The closure takes the form of a one-piece sheet metal plug of inverted hat-shaped configuration having a peripheral flange with a thermoplastic sealant ring located beneath the flange to form a hermetic seal about the opening of the vehicle body. In use, the closure is supported, preferably magnetically, by the head of an insertion tool and is directed by that tool into a floor pan opening or other panel opening of a vehicle body. Depending on the shape of the panel opening, the plug is then temporarily secured in place, with the sealant ring clamped between the flange of the plug and the body panel, either by a partial turn of the plug or by a tool with cam-driven dimpling elements that are forced outwardly within the cavity of the plug to produce a plurality of external enlargments or nubs. The same closure plug may he used for either type of attachment and, following such attachment, the entire assembly is heated (in the normal baking cycle of the painting operation) to soften and expand the sealant ring and produce a permanent adhesive bond between the parts. The use of the paint drain openings to support and position a vehicle prior to plug insertion and attachment is also disclosed.

Isolating shield

An isolating shield is made of a metal sheet material by single step punching process of sustained operation only with a progressive die. A cover plate and a base which are separate members are directly punched as an integral, and then a partial cut imprint is formed by punching the integral between the cover plate and the base. An isolating shield is therefore made for mobile phone or the likes. If the electronic (computer) components or accessories isolated by the isolating shield need repair when using, they are ready to be repaired by opening and upstanding the cover plate. After repair work has been accomplished, the components or accessories returns to an isolated condition by covering and mounting the cover plate on the base.

Reverse buckling rupture disc

An improved reverse rupture disc (10) for use as a safety pressure relief device is provided. The disc is defined by an annular flat flange region (12), a concave-convex disc dome region and a transition region (14) that joins the disc-shaped flat flange region to the concave-convex disc dome region (16). One or more deformations (18) are formed at or near the apex of the disc dome region for weakening the disc to the point that incidental damage to the disc will not weaken the disc any further, thereby ensuring that the disc will reverse at a cerain pressure, and no lower. The disc is also formed with an irregular transition region (20) at the base of the disc and a partial circular groove (30) in the transition region. The irregular transition region of the disc cooperates with a protrusion formed in a support ring disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region. An ungrooved region of the transition region acts as a hinge holding the ruptured disc dome to the flat flange region after the disc has ruptured. The ruptured disc dome hangs over an arcuate projection formed in the support ring, which helps to prevent the disc from fragmenting.

The irregular transition region of the disc cooperates with a shear enhancing means such as a protrusion or notch formed in a support ring or disc holder disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region. A back pressure support means extends over the transition region and potentially over the dome region to prevent vacuum and forward to reverse cyclical pressures in the convex direction from damaging or destroying the disc. An ungrooved region of the transition region acts as a hinge holding the ruptured disc dome to the flat flange region after the disc has ruptured. The ruptured disc dome hangs over an arcuate projection formed in the support ring or disc holder, which helps to prevent the disc from fragmenting.

Low burst pressure, multiple domed, scored rupture disc

A multiple-domed, scored rupture disc (28) having a non-apertured disc body (62) provided with separate, side-by-side, semi-circular concavo-convex bulges (76) and an arcuate line of weakness (68) circumscribing the bulges is provided with a diametrical ridge (74) extending across and serving as a divider between the bulged areas of the disc body.

Scored reverse buckling rupture disk assembly

Rupture disc

RUPTURE DISC Abstract A rupture disc system comprises a rupture disc including a dome portion and a flange portion interconnected by a transition region and a mounting mechanism for mounting the rupture disc by the flange portion thereof in a pressure relieving vent. The rupture disc includes a thickness reducing groove at least partially circumferentially surrounding the dome portion and located in the transition region thereof. Preferably, the rupture disc is of the reverse buckling type and the groove does not completely surround the dome portion so as to define a tab or hinge within that part of the transition region which is ungrooved or not as deeply grooved as a remainder of the transition region. In addition, the slope or radius of curvature may be increased in the region of the tab. The rupture disc also includes an indentation on the dome portion. The indentation is preferably greatest on the dome portion at a location spaced from the transition region and directly between the tab and a crown of the dome portion. In addition, the mounting mechanism includes a lower ring member having an arcuate projection which extends into the vent. Preferably, the arcuate projection is located so as to be relatively close to and so as to align with the tab such that the dome portion wraps about the projection when reverse buckling and rupture occurs. Methods are disclosed for producing the disc with the groove and the indentation.

The device consists of protective plates, made in the form of sheets 9-15, intended for installation on the machine guides with the help of supporting elements: strips 16-22, having profiled surfaces and C-shaped hangers 26, 27, 30, and brackets with rollers. With the help of the profiled surfaces of the film, they are connected to each other, and the C-shaped clamps and brackets with rollers are designed to interact with the machine guides. The end sheets 9 and 15 are intended for connection with movable calipers 3 and 4. To limit movement of one adjacent sheet over the other, limit stops 32 installed on the sheets. 1C. f-ly, 3 ill.

Telescopic cover of machine tool

A telescopic cover of a machine tool is provided with two movable covers connected by a joint, two pulleys mounted on the joint, and a single wire stretched around and between the two pulleys. One and the other ends of the wire are secured to the mobile element, and a middle portion of the wire to a fixed portion. In this arrangement, the two movable covers connected by the joint move half the movement stroke of the mobile element in association with the action of the mobile element.

Protective device

Described is a protective device comprising: a plurality of slats (1), each having a front wall (2A) and an upper wall (2B), positioned in such a way that the front walls (2A) are in contact, in succession, to define overall a continuous surface (3) of vertical closing, each upper wall (2B) having at an end a coupling edge (5) defining at least one seat (6) which is C-shaped and open towards the closing surface (3); a plurality of pins (7), each designed to engage at the coupling edge (5) inside at least one open seat (6) of a slat (1); a closing sheet (9), coupled to the pins (7) for being inserted inside the above-mentioned at least one seat (6) of the coupling edges (5), the slats (1) being relatively mobile along a direction of movement (D1) between a configuration of maximum extension (C1), wherein the closing surface (3) defined is maximum, and a configuration of minimum extension (C2), wherein the closing surface (3) defined is minimum, each of the slats (1) has, at the coupling edge (5), a series of protrusions (6A) each defining one of the above-mentioned open seats (6), offset from each other in plan to define recesses (10) between each of the protrusions (6A), and one of two slats (1), consecutive to each other, has, at the coupling edge (5), the open seats (6) at the recesses (10) of the other slat, and the recesses (10) at the open seats (6) of the other slat (1), in such a way that in the configuration of minimum extension (C2) the open seats (6) of a slat insert at least partially in the recesses (10) of the other slat (1).
