Abstract: An apparatus and method for operating an auxiliary hydraulic load at low noise levels. A pump having a capacity which is sufficiently large to supply the load with the necessary volume of hydraulic fluid at relatively low pump speeds is driven by an engine operating at a speed near its idling speed. Throttle control means control the fuel supply to the engine at a level sufficient to drive the pump while maintaining the engine speed near its idling speed. When the engine speed is increased to a predetermined level in excess of its idling speed, means are provided to maintain the output from the pump at or below a predetermined flow rate to not overload the pump means or the auxiliary load. The pump may include a variable displacement pump or a plurality of fixed displacement pumps with means to vary the pump output in response to the pressure demand from the auxiliary load to maintain the torque input requirements for the pump below a predetermined level.

Abstract: This invention decreases the time of an injection molding machine cycle by cutting off communication between the mold and the source of material as soon as injection is complete, and accumulating material for the next charge during the cooling part of the cycle. Pressure is maintained on the material in the mold, and material is supplied to compensate cooling shrinkage, from an auxiliary cylinder in which a minor amount of hot material is accumulated. After sufficient cooling, runner material is drawn back by suction of the auxiliary cylinder. A three-way valve cuts off the main material supply and puts the auxiliary cylinder in communication with the mold.

Abstract: An endoprosthetic bone joint device developed for the elbow, but applicable elsewhere, has two hinge components respectively defining complementary first and second bearing surfaces for mutual articulatory engagement, and each apertured to define third bearing surfaces. When implanted the hinge components are first coupled by a further component passed through the apertures and defining fourth bearing surfaces to articulate with the third surfaces. At this stage all of the bearing surfaces are appropriately engaged and stabilization of the implantation securement is facilitated. Subsequently the coupling can be removed to reduce the effect of distraction stresses on the device. The first and second surfaces are suitably of spherical ball and socket form, and can be of a twinned form, while the third and fourth surfaces are suitably of circular cylindrical form extending diametrally through the ball and socket.

Abstract: The specification discloses a method of making a male, screw-forming member, i.e., a member which forms a screw thread in a plain hole without cutting. The shank of the member is threaded and has three portions, a first portion of constant, circular cross section, a generally conical second portion of lobular cross section at the free end of the shank and a third portion of lobular cross section interposed between the first and second portions.

The member is made by first threading the shank and then deforming the second and third portions to lobular cross-section.

Abstract: The present invention relates to a system for binding of perforated sheets together through their perforations with at least one loop of flexible tape. The apparatus includes a tape feed station, a tape cut-off station, a tape loop forming station, and a tape loop sealing station.

Abstract: An apparatus for shaping successive molded articles from moldable material such as flat food patties from ground beef, ground fish and other moldable food materials. The apparatus has a mold opening in a movable mold for receiving a pressurized charge of the moldable material, an entrance to the mold, a vent from the mold opening spaced from the mold entrance for venting air displaced by the pressurized charge entering the mold opening, and a rigid valve between the mold entrance and vent movable into engagement with a valve seat before the pressurized charge reaches the vent to close the vent when the valve member is displaced by the advancing pressurized charge. The result is that the air and any other gases present are expelled from the mold opening automatically by the pressure of the entering charge and the vent is then automatically closed to prevent any substantial loss of the material through the vent. Then the moving of the mold as to an ejecting position automatically reopens the valve.

Thus, if the shaped portion is, for example, a circular patty such as a hamburger patty it substantially maintains its circular shape throughout the processing.

Abstract: Fibrous web structures in which the individual fibers are uniformly felted in random orientation are produced by projecting a stream of solids suspended in air toward a moving porous collection surface. The fibers are maintained in a controlled condition uniformly dispersed in air during transit from the nozzle to the porous collecting surface and before the stream of air has spread to the point of disrupting the uniform fiber dispersion, the fibers are felted and collected on the porous support while air is continuously passed through the support to insure no gravity free fall of fibers. Liquid or dry adhesive binders may be incorporated into the structure at any convenient stage of the process but preferably before the web structure is formed on the moving support.
