Abstract: A device with a pivoting work arm for carrying and positioning a tool which is moved by a modified Watts linkage powered by a linear actuator is provided with shock absorption adjacent both the fully extended and fully retracted work arm positions. The modified Watts linkage engages a pawl which rotates a lever arm in the same direction to actuate the same shock absorber(s) when the work arm is moved to both its fully extended and fully retracted positions.
Abstract: A fixed displacement vane-type hydraulic machine that includes a cartridge assembly having a rotor, a plurality of vanes carried by the rotor, side plates on opposed sides of the rotor, and a cam ring carried between the side plates surrounding the vanes and rotor to define fluid chambers between the vanes. A housing surrounds and encloses the cartridge assembly, and provides inlet and outlet passages for feeding fluid to and from the chambers. A shaft is coupled to the rotor and extends from the housing. A cam pin extends radially between the cam ring and the housing surrounding the cam ring for preventing rotation of the cam ring with respect to the housing so as to absorb reaction torque on the cam ring with respect to the housing due to pressure applied to the machine. In the preferred embodiment of the invention, the cam pin is affixed to the cam ring, and is slidably received within an axial pocket in the surrounding housing during assembly of the cartridge to the housing.

Abstract: For a fuel injected combustion engine a fuel pressure regulator having a rapidly and accurately regulated output pressure over a wide range of flow rates by bypassing and returning to a fuel tank a portion of the input fuel from a fuel pump through a bypass valve actuated by a flexible diaphragm. The diaphragm is responsive to the pressure of the input fuel on one side of the diaphragm and a vacuum on the other side of the diaphragm having a magnitude which is varied as a function of the flow rate of the fuel bypassed through the valve and returned to the fuel tank. Preferably, this vacuum is produced by a venturi or orifice through which the bypass fuel flows.
Abstract: When a mounting member employed for fine polishing of semiconductor substrates or glass substrates etc. is constituted of a combination of a sheet of continuous porous structure and a template, operating efficiency is lowered by the need to change the template; this is a factor raising production costs, and edge portions of the polishing workpiece get damaged by contact with the template, causing production of defective articles. By making the mounting member for polishing a member in which water repellence was conferred on at least a surface skin layer of a continuous sheet of porous structure, fine polishing without a template was made possible.
Abstract: A non-destructive method and apparatus for determining the thickness of individual layers of different materials in a multilayer structure particularly useful in analyzing the layers in a multilayer plastic fuel tank, utilizes a constant and relatively high frequency ultrasonic pulse transmitted into the multilayer structure and records the time when interference pulses are received to determine the thickness of the individual layers in the multilayer structure. The interference pulses are generated at the interface between adjacent layers of sufficiently different materials and thus, the time between interference pulses is a function of the amount of time needed for the ultrasonic pulse to pass through a layer of material.
Abstract: A collapsible liner for a bulk container made of a flexible material and having seamless top and bottom walls is provided. The liners are formed from a tubular blank folded to form two gusset panels received inwardly of two overlying flat panels. The blank is severed to form triangular portions adjacent opposed ends of the blank and adjacent sides of adjacent triangular portions are connected together to form a pair of generally opposed and generally rectilinear side walls of the liner. The seamless top and bottom walls are stronger than those portions of the liner with seams and are less likely to rupture or leak.
Abstract: Combustible is comminuted and dried, and metal and noncombustible are removed from the coarsely comminuted combustible. Then, the combustible is secondarily comminuted and separated into coarse combustible and fluff which is fine combustible. The coarse combustible of the separated combustible is fed onto a fire grate (2) of a refuse incinerator (1), and burned in flat bed combustion in a primary combustion chamber (4). On the other hand, the fluff is burned in suspended combustion in a secondary combustion chamber (7) with a combustion fluff burner (5) for incinerating combustible. Thus, refuse containing much plastics which is formed into fluff can be efficiently disposed of, whereby the amount of incineration is increased as a whole.
Abstract: Framing apparatus for the assembly of the body parts of a truck cab including a bottom panel, a back panel, and right and left side panels. A framing station has a base adapted to support the bottom panel. Side framers on opposite sides of the base are adapted to support the right and left side panels. The side framers are moved to positions adjacent to the base in which the lower edge portions of the side panels contact the side edge portions of the bottom panel so that they can be connected together. A rear framer is adapted to support the rear panel at the rear of the base. The rear framer is moved to a position adjacent to the base in which the lower edge portion of the rear panel contacts the rear edge portion of the bottom panel so that they can be connected together and the side edge portions of the rear panel contact the rear edge portions of the side panels so that they can be connected together. The several body parts are then permanently connected together utilizing suitable tooling.

Abstract: A computer case with a foam inlay into which are embedded lift devices which can be released by a pressure applied to the top thereof so that they can raise the computer out of the inlay. The application of pressure to the lift devices again causes the computer to be moved down into the inlay again.
Abstract: A fluid filter comprising a housing having first and second plastic cover members each having a peripheral flange and joined together to define a housing chamber having an inlet and an outlet. A filtration media is disposed in the housing chamber between the inlet and the outlet. The peripheral flange of the first cover member has a rib. The peripheral flange of the second cover member has a gutter opposed to the rib. The filtration media has an edge portion compressed between the rib and the gutter to form a marginal seal preventing fluid entering the inlet from reaching the outlet without passing through the filtration media. The edge portion of the filtration media is pierced and anchored by spikes which project from the rib and extend into the gutter. One of the cover members has a welding rib welded to the other cover member by a process of orbital frictional vibration welding to secure the cover members together.
