Abstract: An insulated construction panel having a top end, a bottom end, a first end, a second end, a front side and a rear side, the panel for constructing a single or multi-thickness concrete form, the panel including regularly spaced coplanar passages extending completely through the panel from the top end of the panel toward and through to the bottom end of the panel. For each of the regularly spaced coplanar passages, an angular passage perpendicularly intersecting each coplanar passage at the top end and extending toward and through a portion of a front side surface of the front side and rear side surface of the rear side of the panel, each angular passage extending only partially through the panel from the top end toward the bottom end.

Abstract: An insulating construction panel having a top end, a bottom end, a first end, a second end, a front side and a rear side, the panel for constructing a single or multi-cavity concrete form. The panel includes regularly spaced coplanar passages extending through the panel from the top end toward the bottom end and at least one angular passage perpendicularly intersecting each coplanar passage at the top end and bottom end of the panel and extending toward and through at least a portion of the back end of the panel.

Abstract: There is disclosed a housing for a thin, flat display screen such as a liquid crystal display. The housing is formed of components comprising a front housing section having a front panel with an opening for exposing the screen of a flat screen device placed within the housing and a rear cover therefor which includes a hinged attachment to the front housing section which is recessed and inaccessible from the exterior of the closed housing. The assembly of front housing section and rear cover is secured with tangs carried on the lower rear edges of these components. The housing is adapted to be mounted in the chair arm of a passenger seat of commercial airliners, and includes a mounting bracket permitting it to be stowed within the chair arm when not in use. In this application it is essential that the housing have an outer covering of impact absorbing material to protect passengers from injury upon impact against the housing. It is also important that the housing be tamper and intrusion proof.

Abstract: An armrest that has a plurality of telescopic trays that collapse to allow a viewing device to be retracted from a stowing compartment within the armrest. The telescopic trays can then be rolled back while the viewing device is displayed, allowing the passenger to utilize both the monitor and the trays. The viewing device is connected to a slide plate that slides along a track that is mounted within the stowing compartment. The plate and track allow the monitor to be retracted from the compartment. The viewing device is also attached to a pair of joints, such that the device can be rotated about the x, y and z axis, to allow the passenger to display and move the monitor into the most comfortable position.

Abstract: A display unit that can retract heavy monitors into a stowing cavity when the retracting actuator of the unit becomes inoperative. The display unit has a spring motor with at least two nested torsional springs attached in parallel to provide the torque necessary to retract the monitor. The monitor is connected to a frame such that the monitor can move from a first stowed position to a second viewing position. Attached to the frame and monitor is an actuator typically of the ball screw variety, that rotates the monitor into the two position described. The monitor moves into the viewing position when the ball screw is rotated in a first direction, the monitor further being lifted into the stowed position when the ball screw is rotated into a second opposite direction. The actuator is typically driven by an electric motor adapted to rotate the ball screw in both directions.

Abstract: The present invention is a fiber optic security system for protecting expensive equipment from tampering or theft. The fiber optic security system comprises an emitter for generating signals, a detector connected to an alarm for monitoring the signals and a sensing coupler or photon switch of novel design which is easily mounted to each piece of equipment that requires protection without defacing the equipment. The sensing coupler mounts the tips of optical fiber ends in a position aligned along a single axis to allow light generated by the emitter to pass through. Any attempt to remove the sensing coupler causes the tips to be misaligned and the light to be deflected. This causes an optic path interrupt and causes the detector to trigger an alarm.

Abstract: There is disclosed a pinch valve of greatly improved performance. The pinch valve has a housing with end plates having apertures forming a through passageway to receive a flexible conduit. The housing is split through the apertures of the end plates, into two halves, forming upper and lower saddles that are detachably interconnected to permit assembly of the housing about a flexible conduit, thereby eliminating cutting or breaking of the flexible conduit to insert or to relocate the pinch valve. The upper half of the housing carries a stationary bar or anvil and a circular cam actuator moves the valve member through a complete, 360 degree, rotation in a sinusoidal action movement. This action gives the valve a great mechanical advantage at shutoff position, permitting use of a small, lightweight valve structure.
