GREY COMPOUNDED INFRARED ABSORBING SPECTACLES, GOGGLES, FACESHIELDS AND HOOD WINDOWS USED IN PERSONAL PROTECTIVE EQUIPMENT FOR ARC FLASH HAZARDS

Номер: US20210063771A1
Принадлежит:

An improved personal protective device and composition thereof. The device comprises arc flash spectacles or goggles, an arc flash faceshield or an arc flash hood window to provide optical clarity, specifically color acuity. The spectacles or goggles, the faceshield and the hood window include polycarbonate material for high-impact, high-mass performance, and surface charring during arc flash exposure and provides an arc flash protective rating of at least 4 cal/cm(in the case of eyewear and face shields) or at least 15 cal/cm(in the case of hood windows). 1. A faceshield for blocking arc flash thermal energy , the faceshield comprising:{'sup': '2', 'claim-text': a) an optically clear plastic material selected from the group consisting of but not limited to polycarbonate, acrylic, cellulose propionate, cellulose acetate and cellulose acetate butyrate; and', 'b) a particulate of antimony doped tin oxide coated with a dispersant; and', 'c) the particulate described in b) dispersed within said optically clear plastic material., 'a lens providing color acuity within the visible light spectrum, the lens comprised of a particulate consisting of antimony doped tin oxide that blocks infrared radiation, and an optically clear plastic material, the-optically clear plastic material and the particulate chosen and blended in proportion so that the faceshield will block a range from 3 to 40 cal/cmof arc flash thermal energy, the lens further comprising of2. The faceshield of claim 1 , wherein the particulate of antimony doped tin oxide coated with a dispersant has a size range of about 0.1 to 15 microns per particle.3. The faceshield of claim 1 , wherein the leas provides at least 30% light transmission across the visible light spectrum.4. A faceshield for blocking arc flash thermal energy claim 1 , the faceshield comprising:{'sup': '2', 'claim-text': a) an optically clear plastic material selected from the group consisting of but not limited to polycarbonate, acrylic, cellulose ...

Modular actuator for valves and chokes

Номер: CA2524336A1

The invention contemplates a simple coupling means for interfacing linear acting actuator shafts with valves or hydraulic chokes. The coupling means of the present invention allows either an actuator or an interconnected valve or choke to be rapidly, safely, and efficiently interchanged with a replacement part. The present invention is broadly applicable to a wide variety of actuator types having rectilinear motion outputs and to a large variety of valve and choke types which are operated by linear motions, including gate valves with or without balanced stems.

Apparatus for connecting a valve and an actuator

Номер: NO342247B1
Принадлежит: Expro Americas LLC

Oppfinnelsen vedrører et apparat for kobling av en ventil og en aktuator, hvor apparatet omfatter en valgbar, fjernbar koblingsanordning som koaksialt flukter en distal ende av en vekselgang lineær virkende aktuatoraksel og en proksimal ende av en ventilstamme eller et ventilstammeforlengelseselement; og et grensesnitthus som har en første ende montert til en aktuator og en andre ende montert til et ventillegeme, hvor grensesnitthuset omgir koblingsanordningen og har minst ett vindu i en side av grensesnitthuset for å tilveiebringe tilgang til koblingsanordningen; hvorved aksial vekselgang av aktuatorakselen bringer koblingsanordningen til vekselgang i grensesnitthuset og derved beveger ventilstammen. The invention relates to an apparatus for coupling a valve and an actuator, the apparatus comprising a selectable, removable coupling device coaxially flushing a distal end of an alternating linear actuator shaft and a proximal end of a valve stem or valve stem extension member; and an interface housing having a first end mounted to an actuator and a second end mounted to a valve body, the interface housing surrounding the coupling device and having at least one window in one side of the interface housing to provide access to the coupling device; whereby axial alternation of the actuator shaft brings the coupling device to alternation in the interface housing and thereby moves the valve stem.
