Abstract: A paint spray gun comprises a body having a compressed air supply to atomize paint from a paint source external to the gun. The gun has a needle which is spring urged forwardly and retractable by a trigger to control the opening and closing of a nozzle in a spray head. There are two sealing joints between the needle and the body of the spray gun, and they surround a portion of the needle which is upstream from the paint in the direction that the paint flows along the needle and out the nozzle. A sealing cartridge comprises a cylindrical body enclosing the two sealing joints surrounding the needle, and a prestressed compression spring surrounds the needle and is disposed between the two joints and urges the two joints away from each other against solid surfaces that deflect the joints into sealing contact with the needle. A needle support in the form of a single piece opens at one end in the spray head and at its other end contains the sealing cartridge.

Abstract: An electrical cable connector comprises at least two insulative material jaw members adapted to define between them at least two parallel channels, one for each cable. At least one metal contact member is carried by one of the jaw members in a housing in which it is at least partially accommodated. It has active parts at the front adapted to intersect both channels. Clamping means close the jaw members so as to close the channels onto the cables. Insulative material seals are disposed around the respective active parts of the contact member and linked by a crosspiece. The crosspiece is secured by deformation to the respective jaw member so that it is fastened thereto. To this end the crosspiece is disposed between two ribs which are one piece with the jaw member and are deformed under pressure into a U-shape pressing against the crosspiece.

Abstract: Chains having links in the shape of a figure eight can be made by the method and apparatus of the present invention. The last link of the chain is first held in a secure position. Oval shaped loops are cut from an oval shaped helix in such a manner that the ends of the loops are spaced apart. The ends of the loops are then passed through the eyes of the held last link of the chain. The ends of the loop are then closed and the loop is then grasped at opposite ends of the oval and twisted to form the figure eight shape. The present invention has a collet 30 for holding the last link of the chain, a collet 40 for grasping the loops created from the oval shaped helix. The collet 40 is movable for insertion of the arms of the loop into the eyes of the last link. A clamp 50 joins the ends of the loop and the clamp 50 and collet 40 then perform a twisting motion which results in the loop being formed into a figure eight shape.

Abstract: A spacer for use in a branching electrical connector comprises two jaws and clamping device for clamping the jaws together. At least two parallel channels are defined by the jaws, the spacer being adapted to hold one of the channels temporarily at least partly open. Overridable abutment on the spacer yield when sufficient force is applied to the jaws by the clamping device to enable the temporarily open channel to be closed.

Abstract: A branch connection accessory device for an insulated branch cable to be connected to an insulated main cable comprises a two-part clamping system. This is adapted to clamp the branch cable between the two parts, at least a first of which is electrically conductive. An insulated conductor appendix is factory-fitted, electrically connected and mechanically joined to the first part. It is adapted to be connected to a non-separate branch connector having two jaws, to one of which the appendix is connected and the other of which is connected to the main cable. An insulative seal envelops the device, a hole in the seal providing access to the first part. A well in the seal in line with the other part enable the latter to be operated. The device therefore constitutes a sealed, insulative branch connection accessory device.

Abstract: A furnace for firing an enamel-insulated wire comprising a principal cham, an auxiliary unit for withdrawing a first stream of air and solvent vapors from this principal chamber for effecting combustion of the vapors themselves. A part of a second stream leaving the auxiliary unit is mixed with a volume of air at ambient temperature and passed to the principal chamber; another part is sent to a heat exchanger in which it gives up part of its thermal energy to a second volume of air at ambient temperature which is heated and introduced into the principal chamber.
