Abstract: A disc for use between a bottle body and a cap having an aperture therein. The disc has a substantially planar base which fits within the cap and a circular plate on the base which mates with the aperture in the cap. An elongated land extends across the circular plate and slightly beyond. The ends of the land are tapered so as to provide a snap fit of the disc to the cap. A tab is secured to the land by a flexible hinge. An aperture is provided through the tab so that the assembled structure may be hung from a rod.

Abstract: An alignment device comprising a plurality of hollow arcuate sections secured together at their inner edges so as to form a hollow center with a base support member, an aperture for admitting fluid and scalar indicia about the outer edges of the arcuate section. The device may be adapted to removably accept a rigid rod opposite said base, said rod being adapted for insertion into the chuck of a drill.

Abstract: Self-bonded, balanced nonwoven fibrous fabrics having fibers uniaxially oriented and junction points of biaxially oriented film tissue and fibers in the plane of the fabric, the fibers being primarily oriented in the machine direction with the biaxially oriented film tissue being oriented in the cross direction. The nonwoven fabrics are produced by extruding a molten polymer radially from a circular die, quenching and then drawing the extrudate.

Abstract: A position digitizing device in which a cursor, moveable within a field generated by successively activated grid wires, developes a voltage from the field and, in conjunction with conditioning circuits, yields the electrical intelligence required to indicate its position with a high degree of precision. Currents are successively passed through parallel grid lines at discretely separate distances, the resultant successively positioned fields successively inducing voltages at the cursor coil output dependent upon the position of the cursor in relation to the actuated grid line. Conditioning equipment to which the cursor output is coupled mixes the cursor output with a reference and introduces circuitry responsive to the rate at which the grid currents are successively stepped to translate the cursor output to a time variant wave form.

Abstract: A device to produce and test a thin film of excited gas or liquid comprising a helium resonance lamp having an emission at 584A and including a window in said lamp partially transparent to radiation at 584A. A chamber containing a gas mixture including helium surrounds the window. Windows are provided in the chamber adjacent the lamp window, said windows being transparent to emission emanating from the gas adjacent the lamp window when the lamp is excited by an RF source.

Abstract: An applied force whose mangitude is to be measured is caused to change the spacing between a pair of conductive plates. The resulting variation in capacitance between the plates is employed in an RC oscillator circuit so as to produce a frequency that is reciprocally related to the capacitance. A neutralizing circuit serves to cancel the effect of stray capacitance, and a digital counting device converts the oscillator frequency to a scaled number indicating the magnitude of the applied force.

Abstract: A method and apparatus for supplying a source of olivine grit material, providing a source of fluid pressure, mixing the ingredients in a sandblasting type of gun, and directing the mixture directly against the surface to be treated. The gun may be adapted so as to provide various spray patterns as desired. The fluid pressure may be either a liquid or a gas.

Abstract: A mechanical fibrillator for use with a split film tape extrusion system which comprises means for guiding the tape through the fibrillator, rotating cutter means in the fibrillator, means for forcing the tape into contact with the rotating cutter means, and means adjacent the cutter for collecting dust created during fibrillation.

Abstract: A horizontal wellpointing system is provided wherein a trenching vehicle digs a trench while perforated flexible pipe having a filter material is placed along the trench. The pipe is covered as the trench is refilled and a subsequent evacuating pressure is applied to the pipe by an above ground pump.

Abstract: A car seat for use in an automobile having a lap belt; said seat comprising an integral double wall molded shell; said shell having a seat section, a back rest section, and side panel sections extending substantially the length of the seat section and the back section. Slots are provided through the back rest section substantially adjacent to the associated side panel sections and above the seat section, with the slots being of a dimension to accept the automobile lap belt which is passed therethrough. A restraint harness means is provided in order to secure the occupant to said seat after the seat is secured into the automobile by means of the lap belt.

Abstract: A theft alarm system which includes a transmitter and a receiver which may be fastened together during non-use, with the transmitter being secured to the equipment being protected. Removal of the receiver energizes both the transmitter and receiver. Subsequent movement of the transmitter or attempts to tamper with the transmitter produces a radio frequency signal. The signal is detected in the remote receiver and produces an alarm to alert the person carrying the receiver.

Abstract: A low power, sealed, optically thin resonance lamp having a controllable chemical decomposition source of a triatomic gas and a chemical getter sink in a sealed RF excited discharge. The discharge occurs in a second, extremely pure gas which is present in great excess over the gas produced by chemical decomposition. Excitation of species whose emission is desired occurs by electron impact or energy transfer from the major species which are, in turn, excited by the electron impact.

Abstract: A combination baby carrier and seat comprising a molded doublewalled shell including a seat and a back. A rigid support structure is pivotally connected to the shell. An arcuate integral section below the seat has gear teeth on the outer circumference thereof and a longitudinal slot down the center. A roll extends slidably through said support structure and said slot and is connected at the outer end to a handle. The handle has teeth which mate with any selected section of the gear teeth on the arcuate section. A spring between the other end of the rod and the support structure biases the handle into contact with the arcuate section. Positioning of the handle controls the angular position of the support structure.

Abstract: An oriented thermoplastic sheet is pleated and an adhesive and backing is applied to one face thereof. The other face is then pleat fibrillated to a desired depth. Both faces may have adhesive and backing applied thereto with the structure being centrally cut parallel to the faces. The extending edges of the sheets on the two structures are then fibrillated to a desired depth.
