Abstract: A rocking chair whose rocking action is achieved solely through a linkage mechanism rather than rocking cams conventionally employed. In one embodiment, the chair includes upholstered seat, backrest and armrests which are united in a one-piece structure mounted on a fixed base by means of the linkage mechanism. In the preferred embodiment, the base is provided with a swivel enabling the chair to swivel about a vertical axis. The linkage mechanism allows it to be mounted within the seat frame into a compact space which permits low seat styling and yet, the linkage mechanism is concealed and still functions to provide stable rocking as well as gliding action. In another embodiment, the chair is provided with a footrest and the seat is moveable relative to the swivel into a reclining position when the footrest is extended. Additionally, the backrest may be either fixed to the seat in the manner of a "one-way" recliner or moveable relative to the seat as in a "three-way" recliner chair.

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, an evacuated cylindrical heat entrapment tube composed of a clear glass for energy admission and an elongated, U-shaped heat collector tube centrally located in the heat entrapment tube for passing an inner fluid to be heated. The U-shaped tube is constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror collector concentrates substantially all incoming energy upon the central heat collector tube for providing a concentration factor of about four (4).

Abstract: A method and system for tank overfill prevention comprising the steps of supplying fluid to the interior of the tank by means of a dispenser, measuring the dispenser pressure P.sub.d and flow rate Q, determining at equal time increments .delta.t a number of quantities representing tank pressures, another quantity representing the rate of increase of tank pressure with respect to time, comparing the quantity thus obtained with a present critical value, and shutting off the fluid supply, if this said quantity exceeds the said preset critical value and if the said flow rate Q is less than a preset critical value.

Abstract: A handle-operated, wall-avoiding, three-way recliner utilizes a track system for moving the chair from the TV position to the fully reclined position. However, in contrast to conventional "track recliners", the track does not come into play until the chair has been moved to the TV position through means of a linkage system. Such movement is preferably initiated by a handle operatively connected to the footrest linkage which is biased closed by a yieldable spring mechanism.

Abstract: A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, a collector tube composed of a clear glass outer tube for energy admission and for passing an inner fluid, the collector being generally elliptical in nature constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror concentrates substantially all incoming energy upon the central collector tube for providing a concentration factor of about four (4).

Abstract: A rocker-recliner chair including a base, rocker cams mounted on the base, a unitary seat and armrest assembly mounted on the rocker cams by a novel linkage system for movement between a closed or generally upright position with the associated footrest closed, a TV position wherein the footrest has been extended and the seat inclined relative to the rocker cam, and any one of a number of advanced reclining positions where the footrest remains extended and the backrest has moved relative to the seat while the seat has moved relative to the rocker cam. When the chair is in the TV or any advanced reclining position, a "rock-blocking" mechanism prevents forward-rearward rocking of the cams relative to the base, however, the cams are permitted to rock rearwardly to permit movement of the seat into advanced reclining positions. In the preferred embodiment, actuation of the footrest to the TV position is initiated by means of a handle positioned on one side of the chair.

Abstract: An improved brush contact for a phonograph tone arm dynamic stabilizer. The contact includes bristles on a base, with free ends fanned in an arc.

Abstract: A cross member includes a steering shaft support and mounts a ground engaging wheel at each end thereof via a component mounted at each end of the cross member for partial rotation about a vertical axis. A steering arm extends from this component which is adjustably clamped to the steering arm. A connecting rod extends from each steering arm to a centrally located pitman arm extending from the steering shaft which in turn is mounted on the steering shaft support. Preferably, one connecting rod freely hooks onto one steering arm and to the pitman arm with the other connecting rod being hooked to the other steering arm and to the first connecting rod. The angular relationship between the pitman arm, the connecting rods and the hooked ends of the steering arms causes the wheels to turn at different radii and the hooked connections provide the necessary up and down movement without excessive play or clearance thus eliminating the need for more expensive pivot type assemblies.
