  • Patent number: 4369574
    Abstract: This invention relates to a kind of peel concentrating clearance box, in which a peeler is inset into the surface of a columnar box and upon paring, the peels will enter into the box along the slot of the peeler so as not to be thrown about. After the paring is finished, a top lid can be turned to open and a scrape plate follows the top lid to be pulled out and the scrape plate will empty all the peels collected in the box. This invention is not only easily operated but also can avoid a dirty situation.

  • Patent number: 4367989
    Abstract: A portable device for collecting particulate gold bearing material from rock crevices and the like which include a gas engine driven air blower having shoulder straps for mounting on the back of a user, the air blower being connected by a flexible duct to an elongated flexible conduit having a nozzle or crevice tool connected to the conduit front end, a container having an air outlet connected to the rear end of the conduit and adapted to be dragged along on the ground, the duct having an outlet end connected to the conduit in communication with the conduit central passage so that the air blown into the conduit from the blower provides a jet pump action to suck particulate material into the nozzle, through the conduit central passage and into the container for collection with air being discharged through the container air outlet together with a deflector within the conduit central passage for radially deflecting the stream of particulate material flowing within the conduit central passage.

  • Patent number: 4366799
    Abstract: An exhaust gas recirculator for an internal combustion engine having an exhaust pipe, an intake manifold and a carburetor throttle valve. The exhaust gas recirculator comprises an EGR passage which makes the exhaust pipe communicate with the intake manifold, an EGR controlling valve and an EGR valve respectively arranged in the upper and lower portions of the EGR passage. The EGR valve operates in association with the carburetor throttle valve for metering the flow of EGR gas. The EGR controlling valve is separated by a diaphragm into an EGR gas chamber communicating with the EGR passage between the EGR controlling valve and the EGR valve and a negative pressure chamber communicating with the intake manifold.

  • Patent number: 4364829
    Abstract: An oil filter suitably formed to provide integrally therewith a turning attachment to facilitate the interchanging of oil filters on engines and the like which include an oil filter canister. In the preferred form the filter body has substantially cylindrical configuration, upon which an interlocking instrument is disposed on an outer surface thereof. Various forms of the invention provide an interengaging implement to coact with the interlocking instrument selectively so that the oil filter canister can be rotated in either direction along its longitudinal axis by means of lever bars which in one form are affixed to the interengaging implement and pivoted thereto so that when not in use, the lever bars can be folded to reside substantially parallel to the outer annular walls of the canister.

  • Patent number: 4361474
    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.

  • Patent number: 4358989
    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.
