A bent metal plate (1) is non-detachably connected to a flat plate (2) by means of plastic strips (7, 8). In order to produce this connection, the two parts (1 and 2) are inserted into an injection tool in a secured position. During the injection process, the plastic is deposited in the form of strips along the parts (1, 2) and also penetrates into holes (5, 6) which are arranged in the parts (1, 2). The connection is suitable for large-scale production and has the advantage that the connected parts need not be aligned subsequently. In addition, the transmission of body sound from one part to the other (1, 2) is attenuated. The connection is predominantly used in the construction of machine frameworks. ...

CONTROLLING TEMPERATURE OF ROLL

Controlling the operation of a cooling circuit

In a closed cooling circuit, water is fed from a common gas/water reservoir (6) via a user (5) and pump means (7) to an air/water heat exchanger (1). The gas in the gas/water reservoir (6) is able to pass into a storage means (9) via a compressor (8). When the cooling circuit is switched off, the water present in the heat exchanger is removed from the heat exchanger by a shut-off valve means (10) being opened, thereby allowing the gas to expand and enter the heat exchanger via inflow opening (4). The cooling water from the heat exchanger (1) is then stored in gas/water reservoir (6). When the circuit is switched back on - pump means (7) being operated, gas present in the heat exchanger (1) is forced by the cooling water back into the gas/water reservoir (6) though discharge line (B).

Portable and Automatic Vulcanising Device for Pneumatic Tyres.

19,881. Peruzzis, R. de C. de. Sept. 6. Portable vulcanizers. -A portable vulcanizer for repairing tyres and the like consists of a hollow casing A having one or more faces shaped to fit the tyre, and adapted to be heated internally by a lamp B. The lamp B comprises a cylinder filled with an absorbent material D such as amanthus, and a gauze - covered space E which serves as a burner. Air enters by a restricted opening G, direct draught being excluded by a shield N, and the burnt products escape through holes in the top of the apparatus. The lamp, burning alcohol or the like, projects its flame on to the curved sole F. When the sole is heated to the desired temperature, namely, about 135‹ C., the quantity of alcohol vapour generated is greater than can be burnt owing to the restricted air supply, the result being that the flame draws away from the sole towards the air inlet. The thickness of the sole varies, to obtain a uniform temperature.

Method and apparatus for cooling a condensing gas forming tool

A method of cooling a mould tool that is comprised of or includes at least in part (3, 4) a porous material having communicating pores, such as a microporous metal or metal alloy, with the aid of condensed gas, preferably CO2.

Method and apparatus for controlling the temperature of molds, dies, and injection barrels using fluid media

Method and apparatus for controlling the temperature of molds, dies, and injection barrels using fluid media

For controlling temperature in the molding of plastics, metal, ceramic, or die-casting, a circulator supporting a molding machine includes a fixed displacement pump driven by an electronic servo motor for volumetric metering of thermal fluid to or from the molding machine. A pre-set or dynamically controlled volume and flow rate profile matches the heating and cooling requirement of a molding machine and process. Volumetric metering may be based on parameters such as time, machine cycle status, temperature, pressure, and/or flow rate. Fluid may be circulated through the mold at positive or negative pressure at fixed, variable, or pulsed flow. The supply side in a fluid loop may be restricted so as to cause a pressure drop in or upstream of the mold, die or barrel, and seed bubbles may be injected into the fluid flow to excite vaporization and lowering of the fluid temperature.
