Abstract: A rotary internal combustion engine with four vanes carried by a rotor engaging an internal oval housing surface to define four chambers that orbit the rotor axis. Two of the chambers, diametrically opposed, are operated as working chambers on a four-phase internal combustion engine basis in phase with each other. Supercharging is continued through an early part of the volume expansion and firing phase, whereby the rate of expansion per degree of rotation is substantial at the time firing is initiated. The other two chambers are operated as air pumping chambers to supercharge the working chambers via an air pressure accumulator. A lubricating liquid within the chamber is introduced into the pumping chambers for engine lubrication with excess being returned to the accumulator. The pressure of the liquid is applied hydraulically against the vanes to urge each radially outward with equal force.

Abstract: Carbonation enhancer having a cylindrical shell that is closed at one end by an envolute wall spaced from the inner end of a withdrawal tube, the output stream of a conventional carburetor is directed tangentially into space between the shells and caused to move in a spiral path toward the envolute closure wall by a spiral vane in the space and on reaching the envolute wall to move radially inwardly and into the inner end of the withdrawal tube to travel axially in a direction opposite that of the spiral path with the stream exiting the tube to enter the inlet manifold of the engine. Waste engine heat is applied to the exterior of the cylindrical shell in an amount sufficient to vaporize liquid fuel droplets centrifuged thereagainst from the stream as the latter traverses the spiral path portion of its travel from the carburetor to the intake manifold.

Abstract: A pastry bag improved in that a continuous band of coacting fastener components are secured to the inside of the bag a spaced interval from its large filling end; such components being of the conventional pressure engageable, forcibly disengageable, hook and loop type. Preferably, the bag has folds facilitating proper registry of the fastener components. The interval, which is slitted along the fold line, allows finger gripping for forcibly detaching the components.

Abstract: An airtight, open topped receptacle of transparent material totally immersed in inverted position in the water of an aquarium in spaced relation to the side walls of the latter. The lower periphery of the receptacle is spaced above the bottom of the aquarium to allow newts to pass freely therebetween. An air supply feed line supplies air into the receptacle so that an air bubble chamber is established in the latter. An aquarium bottom cover is heaped to extend into the air bubble chamber. For newt training purposes, an optional closure structure is provided for temporarily preventing movement of the newts out of the receptacle.

Abstract: A point for welded removable attachment to a mild steel blade shank and tube to constitute an ammonia applicator blade, such point being cast of high chrome iron to be extremely wear resistant. The point tapers forwardly in width and its generally horizontal bottom slopes downwardly in its forward portion so that outwardly projecting lips along its lower edges not only laterally open and break up soil for swifter ammonia absorption but also tend to pull the blade down into the soil. The point has a V-shaped opening for accommodating the blade shank to which it is butt welded.

Abstract: A magnetic door stay retainer for retaining a swinging door in a closed position in a door frame. The retainer automatically holds the door in a closed position in a door frame when the door is closed. The retainer is adjustable in controlling the amount of force required to open a door when, for example, wind gusts tend to blow the door open.

Abstract: A cooling apparatus, having an evaporative cooler interfaced with an insulated air chamber and detachable therefrom to be replaced with a solar heater collecting panel, said insulated air chamber being connected to a house or other structure by air passage means and said evaporative cooler operable by other than the conventional electrical energy sources as well as the usual electrical energy source, said assembly to be used for the cooling and heating of houses and other structures.

Abstract: An oil well pump drive including a drive unit that is hydraulically actuated by a double-acting hydraulic cylinder to reciprocate vertically. An endless chain is entrained over vertically spaced sprockets carried by the unit, with one flight of the chain anchored against vertical movement and the other flight is secured to the pump polish rod so that the vertical motion imparted to the polish rod is double that hydraulically imparted to the drive unit. The polish rod load on the chain is opposed by a counterweight connected thereto by a chain extending over an elevated pulley. The output of the hydraulic pump supplying the hydraulic cylinder is cam controlled so that the motion of the drive unit is smoothly decelerated and accelerated as the unit approaches and moves from the upper and lower limits of its movement.

Abstract: A hand-grippable device having hanger loops at its opposite ends for detachably hanging keys, an alarm whistle, identification tags and the like. The device also includes provision for releasably securing a selected set of keys, preferably three, thereto in such spaced positions along its length as to project outwardly from between the fingers of a gripping hand whereby they can be used to strike or be twisted with force into the person of an attacker.

Abstract: Apparatus for improving a golfer's putting stroke including a pair of parallel, spring tensioned flexible cables mounted in spaced relation above a horizontal platform constituting a putting surface and on opposite sides of the resting site of the golf ball. The head of the putter is provided with grooves that slidingly receive the cables, or a guide attachment is detachably secured to the putter head that has guided sliding engagement with the cables.

Abstract: A four-chamber rotary internal combustion engine wherein each chamber is operated on a four-stroke cycle with adjacent chambers being operated 90.degree. out of phase with each other so that combustion or power strokes are effected adjacent diametrically opposed parts of the housing. Intake and exhaust valving functions are effected by rotary valves constituted of passageways in the housing and rotor, and with adjacent chambers having intake and exhaust connection to separate sets of passageways in the housing.

Abstract: A turbine in the form of an endless "Venetian blind" set of arcuate turbine blades mounted to extend between a pair of endless chains that are entrained over sets of sprockets so that two flights of the blades travel in opposite directions in closely spaced parallel planes. Shafts connect sprockets of the sets to maintain the blades parallel and to deliver to an alternator the torque applied to the sprockets by the reaction of the blades to a fluid passing therethrough.

Abstract: A bicycle seat mounting wherein a connector is interposed between the post clamp and the bicycle seat, such connector being linearly adjustable in its position relative to the seat, and releasably retained in adjusted relation by a nut and bolt combination. The connector is pivotally secured to the post clamp by another nut and bolt combination that can be tightened to both actuate the clamp and to prevent relative pivotal movement.

Abstract: A high-speed transportation system employing a pivotally supported guide rail structure made of sections connected by expansion joints, with a self-propelled airplane automatically steered to fly along the guide rail with minimum force therebetween by a control system that is inclusive of displacement sensors associated with air bearings coupling the aircraft to the guide rail. A wheeled construction having wheels that can be driven, braked or free wheeling is provided that is automatically lowered or maintained in a lowered position contacting the guide rail whenever the aircraft lacks flying speed or the wheels are either driven or braked. The air bearings urge centering of the rail both vertically and laterally with respect thereto. Flight stability of the aircraft is enhanced by the provision of a ground effect bed, and gust spoilers, with the latter additionally functioning as a noise abatement device.
