Abstract: A taco holder is formed from a blank cut from a sheet of paperboard material. The blank has a first pair of parallel fold lines across the mid-portion and a second pair of fold lines near the side edges so that they can be folded up to form feet. Perforated polygons extending across the parallel lines can be folded to lock the taco holder in position to receive tacos, which are supported on the side panels while being made up and while being heated, as in a microwave oven.

Abstract: The disclosure is of a rotary internal combustion engine constructed in three sections, a compressor section, a combustion section and an expander section. Each of the compressor and expander sections includes male and female rotors with complementary, single turn lobe and groove in which gas, e.g. first an air-fuel mixture and then the combusted mixture, traverse the section. In a lubrication system, a shaft rotates in a cylindrical lubrication gallery. Oil is carried along a helical groove around and along the shaft to small passageways that carry the oil to the rotors of the compressor and expander sections.

Abstract: A shield of rigid sheet metal is of a size and shape to substantially cover the instrument panel of an aircraft. A pair of shrouds on the bottom of the shield are spaced so that each fits over one of the control columns of the aircraft, and aligned holes in each shroud are adapted to receive a padlock to lock the shield in place. The shrouds are of a length to fit closely over the control columns when fully extended to prevent any significant movement of the control column axially and pins, which are secured to the shield, extent through openings in the control columns to prevent any accidental or unauthorized turning. A cylindrical housing open at one end is received over the throttle control, and a lock stem extending vertically from the housing is received in a tube, which is fixed to the shield, when the shield is possitioned on the instrument panel so that there can be no manipulation of the throttle.

Abstract: The micropipette puller of this invention includes a pair of gripping jaws that pull a length of glass tubing in opposite directions. The source of heat is a laser and a beam is directed into a beam directing means, such as a lens or mirror, to refract or reflect the beam against the glass tubing between the gripping jaws. The mirror or lens may be oscillated at various rates and through selected angles in each direction to move the reflected beam a selected amount and at selected rates along a greater length of the glass tubing.

Abstract: The disclosure is of an axial flow rotary internal combustion engine constructed in three sections, a compressor section, a combustion section and an expander section. The compressor section includes male and female rotors with complementary, single turn lobe and groove in which an air-fuel mixture is compressed and discharged from a port at the end of the groove as the port overtakes and traverses an arcuate intake port in the cylindrical combustion block, which is rotating at a slower speed. After the intake port is traversed and sealed off, an ignition port in the combustion chamber exposes a spark plug and the mixture is ignited. Substantially complete combustion takes place while the combustion chamber is sealed off and isolated. Then an entry port into the helical groove of female expander rotor overtakes and traverses an arcuate combustion chamber exhaust port and the combusted gases are discharged and expanded into the expander section.

Abstract: A top entry expansible tube valve has a generally cylindrical receptacle in the valve body disposed transversely of the flow passageways to receive a slotted core sleeve with a central barrier and expansible elastomer sleeve sealed around it. A generally circular cap closure is bolted to the valve body to seal around the access opening and a perforated sleeve is secured between the cap closure and the core sleeve so that the cap closure and core sleeve, with expansible tube thereon, may be removed as a unit for inspection.

Abstract: The dent pulling apparatus includes a rectangular tubular pulling tool having a wheel eccentrically mounted therein. A pin, which has been welded to a dented panel is inserted into one end of the pulling tool and positioned between the wheel and the wall of the tubular member so that a pull on the pin tends to rotate the eccentric wheel in a direction to tighten the grip. A fulcrum plate is slidably carried on a tubular beam that is positioned parallel to the panel to be pulled and is both supported on the floor and anchored to the vehicle. A lever, on the side of which is carried one or more of the pulling tools, is pivoted on the fulcrum plate so that a pull on the lever pulls the dent out to its normal configuration.

Abstract: A bait casting reel has a clutch mechanism in one side of the reel body. A frame member is securedly fixed across the side reel plates at the back of the reel and includes a slideway in which is slideably mounted a thumb-operated push button. The thumb button is mechanically connected to the clutch mechanism so that, when depressed, the thumb button disengages the clutch for free spool operation. The frame in which the thumb button is mounted provides strength and rigidity to the reel, and the thumb button enables convenient thumb operation while holding a fishing rod.

Abstract: In a fishing reel, there is a main drive shaft rotatably on the reel body. A separable unit shaft may be selectively coupled to either end of the main drive shaft to drive it. The reel handle or crank is secured to a sleeve that is rotatable on the input shaft. Both the handle sleeve and the input shaft carry radial flanges between which are carried a drag disc and a friction washer. Pins on the drag disc engage through holes in the handle sleeve. A drag star pushes on the pins to squeeze the friction washer and adjust the torque that may be transmitted from the handle to the input shaft and, hence, the main drive shaft.

Abstract: An animal trap comprises a complete enclosure with just a small hole in the top wall to provide access to the bait on the inside. The trap is sprung to clamp firmly around an animal's paw only if he reaches down through the hole and lifts the bait. In such case, a trigger arm is raised free of an aligned catch and two thick jaws having no sharp edges are brought quickly together. The initial alignment of the trigger arm may be set precisely by a setting screw, and the threaded engagement with the setting screw prevents misalignment.

Abstract: A nozzle with self-contained high pressure booster pump is carried on a pistol grip handle with a small motor to drive the eccentrically-pump. A portion of the water from a conventional hose fitting flows laterally into a pump cylinder and then radially through the piston itself to exit axially through a check valve and into the pump chamber ahead of the piston. During the working stroke the water is driven out of the piston into a pressure chamber and then through a restricted passageway to exit in a jet stream. Another portion of the supply water is diverted around the pump cylinder to the same nozzle to flush away debris loosened by the jet stream.

Abstract: Fitted eyeglass frames having ear engaging members curved to conform to the full contour of the back of the ear they are to engage and moveable rearwardly with respect to the sidebars for releasing the frames for easy removal. In two forms of the invention, the ear engaging members are pivotally attached to the rear ends of the frame sidebars and magnetic and spring means are provided to hold the ear engaging members in desired contact with the ear. In another form of the invention, a spring loaded telescoping section is interposed between the ear engaging members and the sidebars of the frames, and a setscrew acting in the telescoping connection permits adjustment of the effective length of the sidebars.

Abstract: The abstract is of an archery bow compensator comprising a central rod or core that is threaded at its trailing end into a bow to extend forwardly therefrom. A chamber at the forward end of the rod may be loaded with pellets to balance the rod precisely in the archer's hand. An inertia sleeve carried on the rod moves forward when the bow string is released against the force of a compression spring. When compressed, the spring thrusts the sleeve back against a stop on the core to force the bow firmly into the Vee of the archer's hand against any tendency to jump out.

Abstract: The invention relates to a level indicating device including a container or reservoir and a length of tubing extending from the container near the bottom thereof. Narrow, inverted cups are adhered to the sides of the container so that they may be slipped over the top of a stake driven into the ground to provide a firm, stable support for the container while the tubing is moved to different locations to establish a reference horizontal plane.

Abstract: A low profile carriage is mounted on widely spread wheels to roll along the underwater surfaces of a swimming pool. The carriage is propelled by a high velocity stream of water projecting from a rearwardly directed thrust nozzle. There is a venturi restriction just forward of the thrust nozzle, creating a low pressure zone that induces flow of water through the bottom of the carriage, drawing in leaves and other debris. The water so drawn in passes through a screen, trapping the debris in a removable pod or bin depending from the carriage. The top of the carriage is relatively flat and the depending debris pod is curved downward to form an inverted air foil, whereby the pressure differential between the top and bottom of the carriage biases the carriage against the swimming pool surface traversed thereby.

Abstract: The disclosure is of a spin-cast reel wherein a spool is slidably and rotatably carried on an axial body extension. A rotary shaft carrying the rotor is coaxially mounted in the extension and a drag control knob is mounted at the back of the reel body, also on the axis of the rotary shaft. The drag control knob carries a nut that moves along a threaded rod which, in turn, forces the legs of a U-shaped member against a disc spring to apply a drag force against the side of the spool. Thus, the drag can be controlled from the rear of the reel and on the axis of the spool and rotor.

Abstract: The disclosure is of an arm brace comprising a chest strap which is extended around the chest and fastened snugly in place by means of a Velcro type fastener. A shoulder strap extends over the shoulder from a selected position in back to a selected position in front and extended through a belt loop and secured in place by complementary fastener components. A wrist strap is supported by the shoulder strap and is wrapped around the wrist and adjustably fastened. The shoulder may be completely or partially immobilized by attaching the upper arm to the chest strap at the side, wrapped around the arm and fastened. The forearm may be secured to the chest strap and supported similarly to the wrist support.
