Abstract: An initially plastic mass is interposed between an artificial nail and a toe or finger nail bed under gentle pressure, after applying a parting agent to the nail bed. The mass bonds to the nail, and separates from the nail bed at the parting agent as the nail and mass are removed. The parting agent is replaced by a clinical adhesive.

Abstract: A device capable of functioning as a fluid pump or motor has a shaft provided with an eccentric rotating with the shaft in an axially short cylindrical chamber. A ring is rotatable on the eccentric, the thickness of the ring being close enough to the minimum distance from the periphery of the eccentric to the wall of the cylindrical chamber to cause the ring to roll along the wall on rotation of the shaft. The presence of the bearing interposed between the ring and the eccentric has the effect of adding to the thickness of the ring in this relationship. A high pressure and a low pressure port are closely spaced about the chamber periphery, and a moveable dam is mounted between these ports. A second moveable dam is mounted on the opposite side of the high-pressure port from the first dam.

Abstract: A foldable frame receives and supports fishing poles in the usual upwardly-inclined position. One detector on the frame responds to a force applied to any one of the poles, such as a pull on the line carried by the pole, and activates a bell signal accordingly. Other detectors respond to forces on individual poles, respectively, and activate light signals. The latter signals remain activated (after the force is no longer present) until reset.

Abstract: The machine is coupled to a standard tractor, and normally slides over the ground on a skid plate as the vehicle moves forward. A film roll is supported on the machine in a position to be unwound, and the film is progressively deposited on the ground behind the skid plate. Groove-forming structure under the skid plate are disposed centrally inward from the edges of the film roll, and following wheels depress the edges of the film into the groove. Scraper plates then move earth into the grooves, entrapping the edges of the film.

Abstract: The tackle box has upper and lower trays surrounded by a wall defining a space in which lures can be suspended from the underside of the upper tray. A handle operates a vertical shaft slideable with respect to the lower tray to lift the upper tray and bring the lures far enough above the upper edge of the wall to expose the lures and provide access to the lower tray.

Abstract: The machine is attached to a standard tractor, and has a pair of sweeping rotors driven by an hydraulic system. The rotors are mounted on a pair of booms, respectively, pivotally connected to a structure carried by the tractor so that the booms can be swung laterally to selected positions determining the width of the path of operation. The weight of the rotors, and of the rear portions of the booms, is carried on skid discs forming part of each rotor.

Abstract: A filtration module containing a filter element is provided with an ionization device on the outlet side of the filter module which utilizes the outlet grille and portions of the standard filter element as components of the ionization device.

Abstract: The padded frame of a seat being upholstered rests on a support placing the back of the seat in vertical alignment under a carriage mounted on guides establishing a vertical freedom of movement of the carriage. The carriage has a cluster of resilient cantilever arms extending downward, each of the arms having a follower at the lower end adapted to move along the contour of the seat back. The cover for the seat back is slipped inside-out over the cluster of arms, and relative movement of the carriage toward the seat installs the cover outside-out. Other resilient arms in the cluster are preferably mounted on the frame of the machine, with relative movement provided by moving the seat unit with respect to the frame.

Abstract: The temperature of an electrically heated element is controlled by applying a current until the element reaches a threshold temperature, preferably determined by the expanded length of the elements, and then applying a predetermined voltage-current condition for a selected period of time. This is followed by repeated applications of such voltage-current conditions in response to the cooling of the heating element back to the threshold temperature.

Abstract: A tool for manipulating standard resilient hose clamps is in the form of a flat plate with a keyhole-shaped opening adapted to receive the radial ends of the clamp.

Abstract: This coupling device locks together overlapped lengths of coil-thread rebar by positively interengaging segments of the device with the threading of the respective rebar rods, and positively interengaging the segments themselves for alignment, and to complete the stress transfer.

Abstract: The described modifications of tie connectors are adapted to receive a rope, strap, chain, or other flexible tension member. A portion of the connectors establishes the alignment of the unit with respect to the line of tension, and another portion is provided with a laterally-open converging slot functioning as a jam cleat.

Abstract: A filtration module having a receptacle for a filter element accessible through the outlet opening of the module has light means disposed outwardly from the receptacle with respect to the direction of air flow. The module is also preferably provided with sprinkler means including a spray head disposed outwardly from the module outlet opening.

Abstract: An elongated rail having a cross-section with hook-shaped shelf projections, and adapted for extrusion, is secured to a wall by fastenings and adhesive for transfer of stresses to the stud structure of the wall. The rail has a substantial back portion providing a surface for receiving the adhesive, and for establishing a substantial moment of inertia in bending. Short pieces of the same rail section are secured to the back of the cabinet units in inverted position with respect to the wall rail for hooked interengagement. An abutment is interposed between the bottom of the cabinet units and the wall to maintain the vertical alignment of the cabinet units in selected positions along the wall.

Abstract: The present invention provides a modified configuration of the outer plate of the system shown in U.S. Pat. No. 3,545,711 to facilitate installation, and also provides further developments in brackets for special purposes. One of these brackets incorporates an angular shelf support utilizing the primary attachment assembly for securing the horizontal beam, and which has a diagonal engageable at its lower extremity with a lower board perforation only prior to the securing of the horizontal beam. Another attachment has a bracket provided with laterally-spaced flanges embracing the inner and outer plates to maintain the alignment of the bracket.

Abstract: Plating current in a silver-recovery process is controlled as a function of the cell voltage of the system taken in the absence of plating current, and held as a control determinant. The control is modified to produce certain characteristics at low silver concentration to further reduce sulfiding.

Abstract: The cylindrical rotating grate of an attrition mill is constructed by welding a group of bars in close spaced parallel relationship, and then rolling this assembly into a cylindrical configuration. The meeting ends of this configuration are then welded, and an opening is preferably cut from the rolled assembly. The area cut out in the process of forming the opening is used as a cover. The grate structure includes solid abutments interengagable with the cover to hold the cover in position against the large forces encountered during the operation of the mill, with relatively light securing means adapted to hold the cover in engagement with these abutments. A housing surrounding the rotating grate is provided with an opening through which the machine is charged with material, and this opening is covered by a curtain preferably provided with battens and a weight to hold it in position. A vacuum is applied to the interior housing for the removal of dust, which assists in holding the curtain in position.

Abstract: A tubular section of a duct outlet unit normally is received in an opening in a room wall panel. A grille is rotatably mounted in the outlet end of the unit, and has an axial extension received in a bearing supported by a diametral beam extending across the opposite end of the tubular section. A damper assembly is carried by the axial grille extension, and has adjustment handles extending through a grille opening.

Abstract: The sensitivity of photographic materials is measured by a device that generates a controlled exposure of light of predetermined color characteristics. Color control is maintained by subjecting an electroluminescent light source to excitation by alternating current voltages at particular frequencies selected with reference to the light souce color response.

Abstract: This hinge assembly includes normally interengaged leaves, one of these supporting a D-shaped shaft in fixed position. The opposite leaf has bearing sections with open sectors that admit only the minor transverse dimension of the shaft in a praticular relative angular position of the leaves. An abutment on the first leaf prevents disengagement of the second leaf in a position one hundred and eighty degrees from that position.
