Abstract: A rotator cuff stretching machine with pivoting members provides for simultaneously stretching of the rotator cuff, shoulder and elbow in selective upper arm positions of yaw and pitch angles and selective elbow positions of flexion or extension. The apparatus adjusts to allow internal and external rotation stretching of the shoulder at levels of abduction from 45 degrees to 100 degrees and allows that stretch to be accomplished at various levels of horizontal adduction and abduction. The apparatus comprises an arm assembly which includes a forearm assembly for receiving a forearm of the user pivotably joined to an upper arm assembly for receiving the corresponding upper arm of the user. The arm assembly is attached to a rotating assembly so that rotation of the rotating assembly causes the arm assembly to rotate. The rotation assembly and attached arm assembly is attached to a vertical support that rotates in horizontal yaw on a vertical yaw pivot pin.

Abstract: An eddy current probe with a probe body having at least one eddy current coil is centered on a probe shaft by a pod with a plurality of replaceable centering feet which allows abraded centering feet to be replaced while the balance of the probe is retained and reused. Typically, the probe body is sandwiched between a pair of such centering pods. The replaceable pods comprise matching halves, divided longitudinally, that fit together over the shaft. Each of the centering pods is retained against the body probe by means of a retaining cap threaded on the probe shaft against the joined pod halves urging the pod against the probe body. The pod extends into an annular trepan in the probe body to secure the pods at that end. A face within the retaining cap normal to the shaft or slanted acutely toward the probe and overhanging the pod retains the pod in position around the shaft at the retaining cap end.

Abstract: A traditional sling shot is provided with a sighting mechanism on its upper elastic strap, typically a plurality of marks spaced apart along the strap in a vertical array of horizontal rises, colorations, or channels on a strap alignment side opposite the sling shot handle when the strap is loaded and stretched back into firing position with the handle horizontal and the strap generally vertical. The marks are calibrated to represent respective distances a shot of known size and weight will travel when a respective mark is aligned between the user and a target. The rise may comprise a ring, such as an elastic ring, around the strap biased to remain in a selective position on the strap but adjustable by sliding or rolling the ring along the strap to a preferred position.

Abstract: A pressurized air distribution network of conduits terminates in small, needle-like nozzles adapted to penetrate a wall, ceiling or layers of flooring, or other moisture-laden areas, such as trapped air space beneath cabinets, through an unobtrusive, easily repaired hole. Air is dispersed by positive-pressure nozzles within the area and collected by nozzles of negative pressure relative to the air pressure within the area. To maintain equal air distribution about a large area, air pressure at the several positive-pressure nozzles is maintained approximately the same by an air supply ring disposed about the relevant room. Spaced apart about the ring are several manifolds, each feeding air to a nozzle. The ring is maintained at near constant pressure, that is, with minimum pressure gradation about the ring, by attaching several air blowers around the ring. In lieu thereof, a central blower provides air to a duct which divides at least once into multiple conduits at at least one branch location.

Abstract: A traditional gold pan 10 with a flat center base 11 with a spiral sidewall guide 20 from the pan rim 13 to the pan base 11 is pivotably mounted to a stand at its top, adjustably secured in a selective tilt orientation, and continuously rotated by a drive motor.

Abstract: A method of removal or retardation of growth of hair on the human body by application of phenol, a phenol derivative or a combination of at least two from the group of phenol and phenol derivatives. The element or combination is in the form of a liquid or paste and is applied to the skin and thereafter removed by cleansing. Hair growth is thereafter retarded or eliminated.

Abstract: A stackable semiconductor package is described which has external contact points (pins, pads, solder-bumps, etc.), which are arranged in arrays on the top and bottom surfaces of the package. This package also has internal contact points (bond pads) for connection to an integrated circuit die. The external and internal connection points are connected by a programmable interconnection matrix, which may be manufactured separately from the package body and then assembled within the package. The internal contact points can each be selectively connected to the external contact points, and selective connections can also be made linking pairs of the external contact points. Stacks of such packages, containing different dice, may be formed, creating large, tightly-coupled circuit blocks. A presently-preferred embodiment of the programmable package is described in which the package body and programmable matrix are manufactured as a unit.

Abstract: A plurality of beads with matching transverse faces and longitudinal bores cooperate to form a bendable shaft with a duct therethrough, held in face-to-face contact with a plurality of elastic bands within the duct. Alternatively, the plurality of bands may comprise a single elastic inner tube. The elastic bands may also mutually overlap to provide redundancy in case a band should break.

Abstract: A trailerable, mobile motor vehicle service unit is especially equipped to realign wheels and axles of a motor vehicle driven onto the unit. The unit provides a track on which a motor vehicle is driven and a track ramp portion that can be lowered to the ground to facilitate loading of a motor vehicle. Once loaded the ramp is once again raised to a horizontal position. The unit is lifted from its wheels by 4 fixed-length support legs positioned under the wheel position of the loaded motor vehicle which pivot by action of hydraulic cylinders which draw the respective legs to or extend them from the unit. The unit may also be lowered to the ground by first hydraulically relocating its wheels mounted on a slidable axle frame into a wheel storage area of the unit body frame before lowering the unit on its support legs.

Abstract: An eddy current probe shaft with probe and drive mechanism attached for measuring integrity of a bolt hole, particularly useful for aircraft bolt holes, includes a continuous helical coil manufactured integrally into a one-piece steel shaft providing flexure in the shaft enabling axial self-alignment even when the shaft is inserted obliquely into a bolt hole. The intact, integrated helical coil of flexible steel provides a constant length probe, effectively noncompressible and nonelongatable, flexible under external bias and with a spring constant sufficient to reliably return the shaft to a straight-axis rest position upon release of the external bias. An eddy current probe with a test coil in a probe head is attached at the shaft distal end for measuring cracks and similar structural anomalies in the bolt hole. A drive mechanism is attached at the shaft proximal end for rotating the shaft and probe in the bolt hole for a circumferential scan of the bolt hole interior surface.

Abstract: A reversible spray tip holder for connection to a spray gun comprises a union with like quick-disconnect mounts on each of entry and exit ends for connecting to a mounting adaptor which facilitates connection to the spray gun. A base and a tip housing join by means of a base threaded bolt threaded into a matching tip housing threaded recess to comprise the union. In the tip housing is a tip receiver opening into the tip housing threaded recess on one end and extending to the tip housing exit end at its other end which is closed except for an aperture through which the tip receivable within sprays paint. A tip is received and sealed into the tip receiver, secured therein by the base threaded bolt, with a tip nozzle immediately adjacent to and directed through the aperture. A through passageway extends from the adaptor and spray gun through the base and tip housing to the spray tip. Diverging shields on the tip housing preserve an intended spray pattern.

Abstract: Prepared flat paper stock blank is disposed for assembly into a dual-configuration food and beverage carrier, selectively folded into an upright box with upward-extending side walls and end walls with handle panels extending from the box base around the side walls and meeting over the box as a handle or alternatively into an inverted box with downwardly-extending side and end walls with handle panels extending from the base upward and away from the side walls. When the handle panels are folded toward and around the base side walls, the carrier is disposed to enclose foodstuffs placed in the carrier. When the handle panels are folded away from the base side walls, the carrier becomes a cup and cone carrier, the box being carried inverted. One or more holes are provided in the base section for receiving cups and cones. Hinged sectors are provided at the hole perimeter to cover the hole, lightly connected until mildly urged downward to receive a cup thereby breaking the light connection.

Abstract: An assembly board with a matrix of depending pegs uniformly spaced on orthogonal intersecting lines with pegs at intersections at half the distance adapted to selectively receive from a set, detachable and reusable electrical components housed in uniformly-shaped casings comprising at least 2 electrical connections uniformly spaced for interchangeability of components and stackable at the connections. Components with 2 connections are elongated with connection terminals at each end a standard distance apart. Components requiring a third connection are constructed in an equilateral triangular housing with a base having 2 terminals spaced apart the standard distance and a third connection half the standard distance from the base. Components having 4 or more connections are housed in a rectangular housing having terminals at corners with first opposing sides having terminals the standard distance apart at corners and the sides being spaced apart half the standard distance.

Abstract: An edge guided tool for scoring flat panels comprises a cutter assembly sliding on a track mounted on a conventional T-square vertical rail. A cutting tool body supporting a cutting plate over a panel to be cut is slideably mounted in the track on a resilient spring plate such that when the cutting blade is urged down toward the panel on the bending spring plate, the slide is urged against track sides to prevent further sliding, locking the slide and the blade in an alignment position. With the blade locked parallel to a T-square fence rail, as the T-square is moved with its fence rail abutted along a panel edge as a guide while the cutting blade is urged into the panel, the panel is scored along its length parallel to its length.

Abstract: An expanded elastic ring is supported in an annular groove within a ring outer cylinder for use in vacuum therapy of a dysfunctional penis. The cylinder has an open end for initial placement against a user's body with the penis contained within the cylinder. The cylinder further comprises a cap on a closed end into which a vacuum pump is integrated. The elastic ring expanded around an inner cylinder into an annular groove is remotely released within a vacuum drawn within the cylinder. In a first embodiment, the vacuum effects the release as the inner cylinder is withdrawn into an outer cylinder until the ring falls off of the inner cylinder end. In a second embodiment, push rods extending into the annular groove push the ring past a stationary inner cylinder, effected by rotation of the cap on the cylinder. An inclined face on the cap bottom surface engages the rod, pushing the rod into the annular groove.

Abstract: A removable storage locker sized to fit on a boat transom step platform provides storage and counter space to the boat. The locker includes a hinged upper lid which in its closed position provides a slightly-sloped counter surface for water drain-off at a level commensurate with that of the transom. Hinges are located astern of the transom on a locker rim protruding along the locker hinge side such that the lid opens away from the boat. The hinges are covered by an overhanging, downward-extending, rearward lid skirt to protect the hinge, allowing the lid to open at least 90 degrees with the rearward skirt extending under the rearward rim. The hinge movement is limited by the lid skirt contacting the rim underside, allowing the lid to lean astern until contact is made, the lid thus being stably supported in its open position.

Abstract: A retractable hanging step platform with stabilizers improves the stability of hanging steps found on motor homes and travel trailers. One or more support stabilizers are pivotably mounted on the underside of a step to engage the ground when the retractable hanging step platform is extended for use and to pivot alongside the step when retracted for storage during travel. The legs are also vertically adjustable to accommodate varying height conditions between ground level and the hanging step platform.

Abstract: A hunting simulator having a projection of a moving target in life-size as in a natural environment is provided for practice shooting of a missile such as an arrow, dart, bullet, etc. The missile is detected in-flight in a detection plane set apart from a projection screen so the missile is detected undisturbed before impacting on the screen. The primary detector includes a continuously-illuminating LED emitter and a CCD camera sensor collocated with the emitter with a field of view in a detection area within the plane. Retroreflective tape on a perimeter about the detection area efficiently returns emitter radiation to the sensor. Detection is when a missile causes a shadow on the tape with an interruption of reflected light to the sensor, although in an alternative embodiment, the retroreflective tape is installed on the missile instead of the detection plane perimeter.

Abstract: An eddy current probe having an increased depth penetration. The probe includes an eddy current test assembly formed in the outer surface of a shoe that rotates within a tubular test specimen. The eddy current test assembly includes a pair of differentially-connected electromagnetic coils whose axes are parallel and lie in a plane perpendicular to the direction of the axis of the tubular test specimen. The probe assembly further includes a magnetically permeable backing plate that is closely adjacent to the innermost ends of the two differentially-connected coils. The differentially-connected coils are driven with a signal having a predominant frequency that is less than the natural resonant frequency of the eddy current probe. Flaws and other non-uniformities in the tubular test specimen are detected as the differentially-connected coils travel pass the location of the flaw.

Abstract: A ram air duct directed to a vehicle's windshield receives ram air from behind a vehicle's engine coolant radiator which air is rammed through the radiator to heat the air and into the ram air duct by motion of the vehicle causing a heated air curtain over the windshield. During use at slow speeds, a fan may assist air movement from the radiator into the ram air duct. Supplemental heat may be obtained from electric heaters or the engine exhaust manifolds or both. To reduce vehicle drag due to its trailing vacuum and to the turbulence it causes, an air-collecting scoop is provided at the top of the windshield to receive air of the curtain as it leaves the windshield. The collected air is then ducted to the rear of the vehicle and exhausted into the trailing vacuum to reduce vehicle drag.
