Abstract: A cylindrical chamber full of oil, without any valves or inlet/exit ports for this oil. A piston travels in said sealed cylindrical chamber with a rod on either side, assembled with sealing rings and provided with a series of peripheral axial holes all of the same diameter and equidistant from the piston axis. On the rod anchored to the ram slides a plunger disc supported directly under the piston assembly by two diametrically opposed threaded studs with large heads. Said studs are first threaded through the piston assembly and then screwed through the two holes found on the plunger disc. The upward travel of this disc which stops under and against the piston holes, is prevented each time the dual push-button control is operated since, when operating, these buttons, besides starting the movement of the ram, prevents the upward travel of the plunger disc simultaneously.

Abstract: Disclosed herein is an improvement in a variable venturi carburetor for an internal combustion engine which comprises a venturi portion, a float chamber, a main fuel passage communicating with the venturi portion and with the float chamber, a main fuel jet provided in the main fuel passage and a movable metering needle. A free end of the metering needle is adapted to control the size of the main fuel jet and the base portion of the metering needle is mounted to a suction piston adapted to transversely move with respect to the venturi portion in response to the condition of load on the internal combustion engine. The improvement includes provision of a bypass detouring upwardly from a portion of the main fuel passage upstream of the main fuel jet for discharging vapor of fuel, and the bypass communicates with a negative pressure passage which has an opening in the lower portion of the venturi portion and with an air passage which has an opening in the vicinity of an air horn inlet.

Abstract: Disclosed herein is a hybrid fuel system for an engine which normally operates on fuel such as kerosene, gasoline, propane or the like and is adapted to be used in conjunction with the traditional fuel at selected times during the running of the engine. The system includes an electrolysis chamber provided with a fluid inlet and outlet, a pipe disposed within the chamber to allow the metered dispensing of a portion of the fluid contained within the pipe to an electrolysis area in such a manner that the dissociation of the fluid into its elemental components occurs quite readily. The configuration of the electrolysis area is such that remigration of the elemental components is extremely unlikely, and to this end an angled roof having faces which meet at an area above the pipe cause the elements to be separated and migrate on separate faces of the roof and thereafter to an opening which communicates with a conduit for admission of the elemental components into the engine.

Abstract: Disclosed herein is a spill retrieval mechanism for removing a spilled substance from a liquid surface and placing the substance in a reservoir which includes a trough having a conveyor operatively disposed thereon, a motor system for driving the conveyor, a scoop associated with the trough for directing the liquid and substance to the conveyor, a surface on the conveyor for retaining the spilled substance thereon, and a removal device extending between the conveyor and an associated reservoir to remove the substance from the conveyor and place it into the reservoir. The device also includes structure to alter the angulation of the trough and conveyor to different angles of attack based on the requirements and particular job application.

Abstract: To reduce the piston velocity in a cylinder as the piston approaches the end positions, a signal transmitter is provided for sensing the position of a part driven by means of the piston and cylinder assembly, and thus of the piston in the cylinder. The signal of the signal transmitter is applied to a control unit in which it is compared with a signal from an actuator means. The signal from the actuator means controls the extension and shortening of the piston and cylinder assembly and the velocity at which this occurs, and may be positive or negative. The comparison of signals is so exploited that if it is established by this comparison that the piston is not in the areas of the end positions or, alternatively is in these areas but is activated by the actuator means to move away therefrom, the signal from the actuator means is not acted upon, whereas if the piston is in these areas and approaches the end positions, the hydraulic fluid supply to the piston and cylinder assembly is continuously reduced.

Abstract: Discussed herein is a rapid actuating device for a hydraulic actuator utilizing two or more relief valves to control the hydraulic flow of the actuator for various loading or no loading conditions in order to speed up the required operation time.
