Abstract: This invention relates to the use of the exhaust of an internal combustion engine to contribute to forward motion by a pneumatic device connected directly to the drive train and a motor generator connected to the drive train to contribute to acceleration and to provide regenerative braking. All of the automobiles electrical needs are supplied by recaptured momentum when driving conditions allow. Surplus electricity is stored to further contribute to acceleration.

Abstract: A hand operated tool used to remove the burr from the inside end of a cut metal pipe comprising two rollers adapted to be placed inside the end of a pipe, means to expand the rollers with a hand squeezing motion on the handles of the tool and rotating the pipe or tool until the burr is rolled outward making the inside of the pipe free of any obstructions.

Abstract: The invention relates to a non-lethal projectile of small mass for military or police use adapted to be fired from a standard launcher which projectile either increases in size during flight or at impact to spread the force over a large area to provide a knock-down-effect without body penetration.

Abstract: A transmitter includes case, a thin non-conductive pad with an electrically conductive coating applied to selective areas of the pad, one or more electrically conductive actuator buttons on the pad to activate the transmitter, a thin insulator containing a plurality of separate areas which can easily be selectively punched out leaving open holes, and a printed circuit board containing the electronic circuits of the transmitter. Because all of the internal components can be manufactured as extremely thin elements, the transmitter can be made extremely small and thin.

Abstract: The invention involves a method and compositions for cleaning all oily, natural or synthetic stains or residue from any stone surface, natural or man-made. The method comprises surrounding the stain with a container which is open at the bottom, pouring in a solvent material, covering the container with an airtight lid to prevent evaporation and allowing the solvent to remain on the stain for from 1 to 24 hours. Thereafter the lid is removed and an adsorbent powder is added to the container to the top of the absorbent liquid. The absorbent powder is allowed to stand for 1 to 24 hours and then the powder is removed and the surface being cleaned is allowed to air dry for 24 hours.

Abstract: The invention comprises a safety fastener or collar adapted to securely fasten a holding tank, such as a water heater of any size, to the walls of the structure surrounding the tank. The collar comprises two portions including a non-flexible, rigid supporting collar which is attached to the surrounding wall by a pair of rigid holding legs and a second flexible collar which is also securely fastened to the same supporting wall by use of a joint tie-strap.

Abstract: A direct current machine construction in which the rotor includes a permanent magnet with the stator including winding energizable from a direct current source. In a first embodiment first and second stationary slip rings are connected to an external direct current source. Coupled for rotation with the shaft are to first and second brush assemblies with brushes which are spring biased and protrude radially outwardly from the rotor shaft. The commutator for the windings is stationary relative to the housing and includes a plurality of commutator segments positioned intermediate the slip rings and in a cylindrical manner facing inwardly toward, and for contact with, the commutator brushes. The windings are on the stator with the winding leads being accessible externally of the stator for enabling switching devices to be utilized for changing of the number of turns of the stator windings for thereby varying the motor characteristics, as needed.

Abstract: This invention relates to a time clock device, which contains a hinged time card shelf, which is adapted to be pressed down by the user of the time clock when he inserts his time card into the time clock. Upon pressing down on the time card and time card shelf, which the operator can do with one hand, the time, date, and other desired information, is printed onto the time card by a thermal printer which is actuated by a switch activated by the movement of the time card shelf to its lower or pushed down position.

Abstract: This invention relates to a leash which coils up automatically when the handle is released. The invention comprises a generally cylindrical center portion with handles on either side, which is manufactured in two parts and can be assembled easily. The two parts are then sonically sealed to provide a strong and secure body. A retractable spring is fixedly attached inside the body in such a manner that it easily pulls out and retracts without catching or snagging.
