Abstract: A thermostatically operated dual action control mechanism for controlling fluid actuatable devices such as the shutter and the fan clutch in the cooling system of a diesel engine in vehicles. A valve rod is provided and movable between first and second positions. A hollow passageway is provided in the valve rod, and in one position of the valve rod is open to allow fluid to flow through to one of two exhaust ports in the valve housing to actuate one of the devices. In the other position, the passageway is closed off by a reciprocating needle valve. A thermally responsive sensor element actuates the valve rod between the first and second positions thereof. A limit switch is provided and actuated by the needle valve in the second position of the valve rod and opens up a solenoid valve to allow fluid to flow to the other device.

Abstract: A railway house car side has an elongated opening closed by four doors disposed in end-to-end relation lengthwise of the car with respect to each other, two of the doors, which may be designated end doors, being movable solely lengthwise of the car to uncover the end portions of the opening, the other two doors, which may be designated center doors, being movable transversely, to disalign them transversely of the car side from the end doors and lengthwise of the side alongside of the end doors to uncover the center portion of the opening. The edges of the end doors nearest the respective ends of the car side have beveled flanges engageable with outwardly diverging door stops on the car side to wedge the end doors against the car side when closed and the opposite edges of the end doors have flanges overlaid by the adjacent center door edges to hold the end doors against the car side, and the edge of one center door overlies that of the other to afford a seal between them.

Abstract: A battery separator comprising a microporous sheet formed substantially of a mixture of polymeric constituents. One of the polymeric constituents is an ultra high molecular weight polyolefin having a standard load melt index of substantially 0 and an intrinsic viscosity greater than about 3.0. The other polymeric constituent is either a copolymer of an olefin and an ethylenically unsaturated monocarboxylic acid selected from the group consisting of acrylic acid and methacrylic acid, or a blend of a low molecular weight polyolefin and a polymer of acrylic or methacrylic acid.

Abstract: A device for tying down motor vehicles during transport on a transporting vehicle, such as a railroad car, truck, or the like. The tie-down device includes a winch and a tie-down fitting for effecting a detachable connection to the transported vehicle. The tie-down fitting has a first portion that is adapted to be connected to a chain or other flexible transmitter of the winch and second and third portions, each of which is configured to effect a detachable connection to a respective attachment means of the transported vehicle. The attachment means of the respective vehicles are different, and for this reason the second and third portions of the tie-down fitting are differently configured.

Abstract: A railway house car plug door includes mechanism for moving the door transversely of the car side wall out of and into closed position and for ensuring that the door locking bars are retracted during such transverse movements, and are in locking position when the door is fully closed and comprises a vertically elongated plate mounted for rack and pinion actuated vertically slidable movement in guides on the door. At its upper end the plate is notched at both sides and provided with protruding ears engageable with rolls on bellcranks to actuate the top locking bars, these bellcranks being connected by vertical links to bellcranks controlling the bottom locking bars.

Abstract: A truss-type brake beam has end members with pockets for receiving the abutting end portions of the compression channel and tension bar members with the pocket rear wall abutting the rear surface of the compression member web and the front wall abutting the front surface of the tension member, the end portion of which is bent so as to extend parallel and in abutting relation with the front surface of the compression member web and which extends slightly beyond the end of the compression member, the protruding surfaces of the tension member being joined by a fillet weld to the end surfaces of the compression member web and flanges such that the fillet weld forms an abutment on the tension member engaging the entire end surface of the compression member whereby the tension member is maintained in tension. The end member rear and front walls are formed with windows, the peripheries of which are fillet-welded to the exposed surfaces of the compression and tension members.

Abstract: The invention provides a locking device for railway freight car doors including a wedge-shaped locking pin engageable with the hasp for maintaining the door tightly closed, the wedge being so mounted that it need not be withdrawn from locking position to permit release of the lock.

Abstract: An apparatus for forming envelopes from thermoplastic sheet material including means for feeding said sheets at predetermined intervals along a conveyor means, means for heating the thermoplastic sheet along a narrow transverse zone, means for moving the heated sheet into contact with a curved surface which is of such a configuration that the sheet is folded along the heated zone into an envelope, and means for heat sealing the envelope along the side edges thereof.

Abstract: Railway brake beam head adapted for selective mounting of cast iron shoe or composition shoe and adapted to reject either type of shoe after having been selected for mounting the other type.

Abstract: An electrode cooling apparatus for an electric furnace which permits easy changing of the electrode holder and water tight seals. The electrode cooling apparatus has a cylindrical body with an inner and outer sealing assembly. The sealing assemblies are easily removed with a special tool which is used for assembling and disassembling both the inner and outer sealing assemblies.

Abstract: A thermostatically operated air valve having a valve body, a valve chamber located within the body, a thermal sensor having a push rod extending therefrom into said valve chamber at a first end thereof, a reciprocal valve rod located in the valve chamber with an axial opening therein communicating with a supply of air under pressure, said axial opening of the valve rod communicating with a cylinder located at the second end of said valve chamber, a piston located within said cylinder and slidably mounted on the valve rod for rapid reciprocal movement thereon, an exhaust port in said cylinder having a retractable valving member seated in sealing relationship within said exhaust port, said push rod being in abutting relationship with said valve rod, said push rod extending at a predetermined actuation temperature to push said valve rod into contact with said valving member thereby sealing said axial opening in the valve rod and unseating said valving member from said exhaust port, whereby air in said cylinder i

Abstract: A universal frame member for use in the easy assembling of frames for cabinet doors, mirrors, pictures, etc. The frame body has a decorative surface or face. The under side of the frame body has a pair of end walls and a pair of side walls extending therefrom. The end walls have a mitered angle with respect to the side walls. A flange extends from a first end wall having a lug which permits snap locking onto the second end wall of an adjacent frame body member during assembly of the frame. Screw bosses are located adjacent the second end wall to permit permanent fastening together of an assembled frame body member together with a panel member. A plurality of screw receptacles are optionally provided in a pattern for easy attachment of hinge means.

Abstract: A saw guard for a circular saw having a saw blade and a work piece holder which moves relative to the saw blade to cut the work piece, the saw guard being mounted on the leading edge of the work piece holder and having means for moving the saw guard into a shielding position adjacent the cutting edge of the saw blade while the work piece holder is in a restocking cycle.
