Abstract: A bidet device useable with a toilet has a nozzle (82) which supplies water in an accurate confined spray to the anal or genital area followed by air blown through the same nozzle so as to dry the wetted areas. Both water and air are electrically heated in unit (12) under thermostatic control. A hand grip (60) is used to slide spray conduit (62) and nozzle (82) from a storage position under the lop of the toilet bowl to an appropriate longitudinal position. Switch (52) is then used to control a low voltage circuit which energizes solenoid valves for the alternate supply of water and air. The unit will not operate unless both microswitch (80) [activated by cam (78)] and a pressure switch responding to the user's weight, are closed. In alternative arrangements the spray assembly is carried on an arm turning on a vertical pivot attached to the toilet pedestal or it forms part of a hand-held wand having no attachment to the toilet pedestal.

Abstract: A device for wetting toilet tissue comprising a small, enclosed reservoir fitted with air vents, a finger actuated valve lever, an inlet and outlet orifice and a water flow controlling valve. The device attaches to a bracket that is secured at the other end to the upper toilet bowl flange by one of the toilet seat mounting screws and nuts, positioning the device under the water closet tank and protruding slightly forward. The water is supplied via a small plastic flexible tubing connected to a tubular "T" that is installed between the water closet overflow pipe and the orifice nozzle that is part of the water closet filling ballcock valve. Water flows into the small capacity reservoir whenever the toilet is flushed. To minimize having cold water replacing the ambient-air warmed water in the reservoir, a float actuating lever closes the input orifice when the reservoir is full. A venting orifice allows the release of air being displaced by the inflowing water.

Abstract: A control device for use on film cleaners that remove dust, lint and static charge from plastic film surfaces by the use of high velocity ionized air. The high velocity ionized air removes static charge from the film simultaneously as the dust and lint are blown from the surface of the film by the convective action of the air. The control device is automatically activated when film is inserted between two sets of intersecting conductive fibers, thereby breaking the contact between the two sets of conductive fibers. In addition, the control device can be switched between a constant mode, where the air is on continuously, to a pulse mode where the air is pulsed alternately on and off, in a periodic manner, to synchronize the cleaning action with the stop and go advance of an automatic film printer system. The intersecting fibers also prevent the film from being drawn into the air inlets by the "Bernoulli Effect".

Abstract: An improved method for fabrication of a multiple-element piezoelectric transducer and the transducer produced thereby. A green precursor tape is produced by doctor-blade tape-casting of a slurry containing lead zirconate-titanate (PZT) powder. After drying, individual strips of the tape are stacked between flat plates of previously sintered PZT, and sintered to form PZT strips; Pb from the previously sintered PZT plates makes up any Pb lost from the surfaces of the tape strips during sintering. The PZT strips are stacked interposed by layers of a thermoplastic polymer, and heated to a temperature above the melting point of the polymer, forming a laminate block. This block is then sliced perpendicular to the plane of the layers, forming slabs of alternate PZT and polymer layers; the slabs are then sliced perpendicular to the first slicing planes, forming strips of alternating PZT and polymer material. Electrodes are then added to complete the transducer assembly.

Abstract: Elongated thin strip stock is blanked to form interlocking laminas for electric motor or generator rotors or stators at successive blanking stations.

While the male screw is screwed into the threaded hole through the sliding hole from the fixed side, the male screw is fed to move the return pin in the sliding hole, until the elastic force of the return spring is released to a practically safe level.

Abstract: A method of making a multilayered circuit board wherein at least two layered subassemblies, each comprising a dielectric layer and at least one conductive layer therein, are bonded together. Each subassembly includes a through-hole extending therethrough which is aligned with a respective through-hole of the other prior to bonding. The subassemblies are compressed at a predetermined pressure (e.g., 300 psi) and then heated to a first temperature (e.g., 300.degree. C.) for an established time period, resulting in formation of a bond between the two through-holes. The resulting alloy formed from this bond possesses a melting point significantly greater than that of the subassembly dielectric (e.g., PTFE). Following this time period, the compressed subassemblies are heated to an even greater temperature (e.g., 380.degree. C.), again for an established time period, to assure dielectric flow. The subassembly is then cooled and the pressure removed.

Abstract: An abrasive system and a processing procedure is provided which permits the direct installation of a thick abrasive blade tip cap onto a cast turbine rotor blade during a heating schedule which requires two furnace operations. The composition of the abrasive blade tip cap advantageously utilizes the high temperature performance capabilities of equiaxed or single crystal rotor blade alloys without significantly affecting their mechanical properties as a consequence of the processing necessary to permanently bond the abrasive blade tip cap to the rotor blade. A semi-rigid mat consisting of the preferred abrasive composition is first consolidated in a first vacuum furnace operation. Blade tip cap preforms are then cut from the mat and positioned on the tip of the rotor blade. The preform and rotor blade are then heated in a vacuum furnace according to a temperature schedule entailing heating rates, holding temperatures and durations which are sufficient to bond the preform to the rotor blade.

Abstract: The bow sight assembly is provided for use in archery, more particularly for use with a rangefinder, such as a split image rangefinder. The rangefinder is operated by moving a trigger connected to a positioning mechanism of the bow sight assembly until the instrument reads the range between the bow and the target. Simultaneously, a sight arm on which is located the sight pin rotates about a pivot in direct proportion to the movement of a vertical member connected to the rangefinder. In use, the setting of the sight positioning assembly allows the sight arm and its sight pin to be at the appropriate angle when the rangefinder is indicating the actual range between the bow and the target.

Abstract: A self centering guide pipe axis laser guide is based on the use of three parallel links spaced 120 degrees apart which are engaged to be expanded or contracted. When expanded the links contact the inside diameter of the pipe which accordingly establishes the center axis of the pipe. The driving means for the links is a rotating screw mounted in a base centrally located with respect to the three links. In the front of the base is a laser module whose beam is aligned with the center axis of the pipe once the links contact the inner diameter of the pipe. Gauges mounted in a saddle on top of the pipe determine the proper slope once the center axis has been established. A calibrated scale on the guide can be used for determining both inner and outer diameters of the pipe. While the laser guide has been illustrated in determining the center line of pipes, it also has other uses such as aligning pillow blocks to a center line.

Abstract: An apparatus for measuring compound angles. This apparatus makes use of the standard T-bevel square, which is capable of measuring only a single angle. The invention is a compound angle blade with a split collet joint. The compound blade attaches by replacing the bolt of the T-bevel with fastening means attached to the split collet joint of the invention. This fastening means secures both the compound angle blade and the standard T-bevel square blade. The split collet joint which is attached perpendicularly to the main body of the T-bevel moves in a 360 degree radius parallel to the main body of the T-bevel. The compound angle blade is capable of rotation in approximately a 180 degree radius relative to the split collet joint. The combination of the rotation of the split collet joint and the compound angle blade allows for compound angle measurements both perpendicular and askew relative to the angle of the standard T-bevel. The angles of both blades are fixed by the same fastening action.
