Abstract: The specification discloses a seat belt assembly having a plastic encapsulated, molded in place steel strap and a method for fabricating by vinyl dip-molding. Fabrication of the assembly includes forming an elongated, flattened structural member having a hole for connecting the structural member to a vehicle, securing a spacing block over the hole of the structural member and dip molding a resilient coating generally over the entire assembly. The coating is cut on three sides of the blocks to form a moveable, cupped flap permitting removal of the spacing block and exposing the hole so a coupling means can pass through the hole thereby connecting the seat belt assembly to the vehicle. After connection, the flap is returned to its original postion encapsulating the structural member so the hole and coupling means are covered.

Abstract: A chiller for edible food products of the type employing hygroscopic liquid refrigerant is disclosed. The chiller includes an enclosure having an entrance and an exit. A conveyor transports edible food products within the enclosure from the entrance to the exit thereof. The conveyor defines a plurality of angled flights or runs which extend within the enclosure in spaced, parallel relationship to each other and transport the product generally vertically and horizontally along each of the flights within the enclosure in a serpentine fashion. A liquid refrigerant supply including a distribution pan is supported above the enclosure for directing liquid refrigerant downwardly over the edible food products carried by the conveyor. The liquid refrigerant contacts or intersects several of the flights in a cascading manner thereby contacting a plurality of the food products which are vertically spaced and carried on different flights of the conveyor.

Abstract: There is disclosed herein a method and apparatus for fabricating a pulley which the pulley rim is fabricated from a cylindrically-shaped blank of constant diameter which is deformed by relatively movable die forming members so as to form a ring having a V-shaped cross section which may then be assembled to a hub member. Auxiliary forming dies are also disclosed which may assist in the proper formation of the V-shaped cross section. In another form, the pulley rim is fabricated with multiple annular V-grooves. Apparatus effective for carrying out the above method is also disclosed herein.

Abstract: A snap fastener attaching system employs a moveable carriage assembly which is controlled in linear motion by a belt system coupled to an actuator mechanism. The carriage assembly includes clamping means which are sequentially operated to clamp a garment on the assembly after emplacement by an operator. The depression of a start button enables the actuator to traverse a shaft. Associated with the actuator is a pivotable arm which is located in proximity to a selected shaft of a cam-containing turret assembly. As the actuator moves, the carriage moves proportionately due to the belt coupling system. Each time the actuator arm contacts a cam along the turret shaft, a fastener is emplaced on the garment by the snap fastener attaching machine associated with the carriage assembly. When the last fastener is emplaced, the apparatus is automatically returned to the starting position to enable accommodation of the next garment.

Abstract: The fitting assembly embodies a pair of fittings, one of which is in the ure of a union having a thread on one end, a head on the other end and an axially disposed through aperture which has an enlarged central section provided with a sealing shoulder on the end. The second fitting is in the nature of a metal or plastic tube which has a locking end divided into four quarters which permits the end sections to contract when advanced into the aperture and to expand into the central opening to form an anchor and a seal with an O-ring on the tube end when compressed on the sealing shoulder. The assembled fittings may, if desired, be rotatable relative to each other so that the union can have the thread rotated, via a tool engaged with a suitable wrenching surface, in the threaded aperture to which it is to be connected and the second fitting turned to have its end mated with an element to which it is to be joined.

Abstract: A velocity check valve is provided which can be installed in oil and gas well production systems to prevent loss of fluid and possible fire in the event of a break or leak in a control line connected to a high pressure flowline or a vessel, such as a separator. In one aspect, the valve includes a seat sleeve containing a ball biased toward unseated position with the ball and sleeve being dimensioned so that when fluid flow past the ball exceeds a maximum rate, the resulting differential pressure across the ball will cause it to move to seated position. The arrangement is such that the ball is free to rotate, except when seated, so that it can present different areas of its surface to the seat to thereby distribute wear on the ball more evenly over its surface. The seat sleeve and ball can be situated in a bore extending from one end of the valve in such a manner that the seat sleeve and ball can be removed from the housing without disconnecting the valve from a line to which it may be connected.

Abstract: A plurality of cages are arranged side-by-side on a frame in one or more horizontally spaced rows and if desired in spaced vertical tiers. The commonly facing sides of each spaced row include coverable access openings and poultry confined in the cages are removed through the openings onto a generally horizontally moving conveyor movable vertically adjacent the cage openings to each tier. Preferably, the conveyor is an endless belt type and each tier includes horizontally spaced rows vertically spaced above each other, the conveyor being movable vertically between the rows.

Abstract: A laminated structural member is fabricated with one layer of sheet material such as plywood or fiberboard and an adjacent layer bonded thereto and formed from a mixture of scrap particles of thermoplastic wire and cable insulation, wood particles, comminuted paper, sawdust, and a suitable resin binder. The fabrication procedure is carried out by initially forming a mixture of reclaimed thermoplastic wire or cable insulation, a thermosetting binder, and one or more wood like fillers, such as wood chips, comminuted paper and sawdust and mold release agent. The mixture is then placed in a mold with the sheet material and is subjected to heat and pressure to form a structural member.

Abstract: There is disclosed a valve having a spool sealably slidable longitudinally within a bore in its body between alternate positions for controlling flow of a first fluid between lateral ports connecting with the bore. The spool is urged toward a first position by a force due to a spring arranged within a chamber at one end of the bore, and to a second position by a force due to the pressure of a second fluid acting across a piston reciprocable within a chamber at the other end of the bore. A conical shoulder on a head of the spool engages a conical seat on the valve body at the intersection of the other end of the bore with the piston chamber so as to locate the spool in its second position and form a metal-to-metal seal with the seat.

Abstract: There is disclosed a valve having a valving element longitudinally reciprocable within a bore in the body of the valve between alternate positions for controlling the flow of a first fluid between lateral ports connecting with the bore. A piston connected to one end of the valving element is urged in a direction to move the valving element to one position by a force due to the pressure of a second fluid acting over the piston, and a stem on the other end extends through the valve body to provide an externally accessible part which may be manipulated to shift the valving element between its alternate positions. Means are provided for holding the valving element in its one position, automatically in response to manipulation of the stem to shift it into that position and irrespective of the pressure of the second fluid acting over the piston.

The valve and deflector position are controlled by an actuator responsive to the pressure differential between the inside and outside of the building. Preferably, the inlet opening is a longitudinal slot extending the length of the building along each side at the ceiling and the exhaust fans are positioned at the floor. Preferably, a louver in front of the opening controls the effective size of the opening and the deflection angle of flow into the building.

Abstract: An electronic circuit particularly suited for use in a precision lead screw generator to monitor and control linear displacement of the carriage and cutting head and angular displacement or rotation of the workpiece at a preselected, fixed ratio. Rotation of the workpiece is controlled by a phase-locked electronic servo loop which divides one revolution of the piece into a preselected number of discrete increments. Similarly, linear displacement of the cutting head is controlled by an electronic servo loop, including a laser interferometer, which divides a selected unit of displacement into discrete increments. A master oscillator and appropriate frequency dividers incrementally step the respective servo loops at a frequency ratio corresponding to the desired pitch or lead of the final product.
