Abstract: A golf club alignment device for recording a sight pattern showing the optimum position of the handle end of a golf club when held by a golfer addressing the ball and for reproducing that position. The device has a sighting barrel that is attached to the shaft of the club in spaced-apart, generally parallel relation. Adjustable linkages between the sighting barrel and the clamp attaching it to the shaft allow movement of the top of the barrel toward and way from the shaft and to the golfer's left and right. The barrel is moved until sets of cross hairs across its top and bottom come into alignment with one another when viewed from above by the golfer. The resulting adjusted barrel position, reflective of optimum location of the club handle, is maintained by securing the barrel against further movement. In subsequent shots, the golfer addressing the ball moves the club handle up or down and to the left or right until the sets of cross hairs are again brought into alignment.

Abstract: A variable force exerting clamp assembly having a variable clamping area. A stretchable strap which deforms or "thins" to a smaller width in response to stretching is provided with a first work-engaging clamp secured at one end thereof and a second movable clamp which is slidable between the ends of the strap. The clamps are disposed for engaging a workpiece or workpieces between each other, and tension is applied until the strap is stretched to exert the desired force on the members, whereby, upon release of the tensional force, the strap tends to assume its original configuration, and the second clamp exerts a clamping force on the strap responsive to the strap expanding to its original width.

Abstract: A threading assembly including biasing means for biasing a threading tap or die in a selected direction and a reversible ratchet assembly for applying a torque about an axis coinciding with the axis of the tap or die. An alignment guide concentrically aligns both the axis of the torque and the downward bias, and a threading chuck is secured to the ratchet assembly for clamping the threading tap or die therein. The longitudinal axis of the threading tap or the central axis of the threading die coincides with the axis of the forces applied to its.

Abstract: An adapter for providing electrical access to individual circuits of a telephone circuit cable head is disclosed. The adapter has an elongated rectangular housing and is intended for placement between rows of receptacles of the cable head and protective plugs that mate with the cable head. Five sets of pins and sockets per receptacle are supported by the housing, with the pins for each set extending downward from a lower planar surface for engagement with sockets of the cable head and sockets for each set extending inward from an upper planar surface. Three sets of pins and sockets for each receptacle are connected to one another, providing uninterrupted electrical contact. The other two, coupled to tip and ring wires, are interrupted by a gap leaving pin and socket ends within the housing. These ends have wires joined to them, the wires extending outward for connection to test equipment. The wires in turn are coupled to a connector half for use with computerized test equipment.

Abstract: An unfolding ladder assembly for attachment to a tailgate is disclosed. The assembly includes a pair of plates for attachment to the outside of a tailgate, the plates providing surfaces against which edges of side frame members are biased in deployed position. Pivot pins are connected to the plates in spaced-apart relation, the pins engaging slots inside members of a step supporting frame. The frame is movable from a forward, deployed position where the pins engage rear portions of the slots, and the upper edges of said frame members, which form an obtuse angle with respect to the length of the frame, are biased upward against the plate surfaces. The step is projected rearward and downward from the tailgate by this means. A lower step frame supporting a second, lower step is pivotally attached to the lower end of the upper step frame. Notches in the side members of the lower step frame have surfaces that engage the upper step and hold the lower step in position.

Abstract: A system for locating a buried structure in which a signal radiating from the structure is measured by its reception on the surface of the earth with the signal being attenuated by a selected amount and then measured by reception at varying distances above the earth with a lesser attenaution, whereby the depth of the object below ground is indicated as a function of signal level differences and attenuation.

Abstract: A three-layer insulated concrete panel includes as the middle layer an insulating slab having grooves which provide a form for casting of concrete supporting ribs integral with a layer of concrete cast over the grooved face. A layer of material, such as particle board, is bonded to the ungrooved face of the slab. In preparing the panel, the slab is placed on a flat surface with the particle board face down. Forms are then placed in spaced-apart relation to panel edges, and concrete is cast into the forms and grooves and over the grooved panel face. The insulating slab provides a form for casting of supporting ribs and is permanently retained in the panel, giving it a high insulating value.

Abstract: A multilayer chemical barrier fabric is made up of a base sheet of nonwoven polypropylene laminated on one side to a multilayer film sheet having a film of ethylene vinyl alcohol sandwiched between films of nylon with a surface film if linear low-density polyethylene bonded to the outer film of nylon and laminated on the other side to a multilayer film sheet having a central film of polyvinylidine chloride, an inner film of ethylene vinyl acetate, and an outer film of low-density polyethylene. Fabrics having this structure show resistance to breakthrough within eight hours for all fifteen chemicals listed on the ASTM F1001 chemical test battery. A composite fabric having the above structure, but omitting the multilayer film that contains polyvinylidine chloride, is also disclosed.

Abstract: A paystation telephone level control system is disclosed including a telephone receiver driven by a local amplifier and wherein two sets of attenuating resistors, a coarse attenuation set and a fine attenuation set, interface with connectable terminals of a binary control crosspoint switch. The presence or absence of coin tones and dialing tones are detected and the crosspoint switch discretely controlled by their presence to effect discrete levels of attenuation of signals fed to the receiver. In addition, the lever of attenuation during voice communications is a function of a pre-adjusted attenuation and a user selection.

Abstract: A space structure which is formed in space. The structure is comprised of an expandable, flexible, generally non-elastic, impervious mold which is arranged in a collapsed state in a container which separates in space to expose the mold to the space environment. The mold is formed to a predetermined configuration by the injection of chemically hardenable filler materials. The vacuum properties of space permit very low injection perssues for the injection process, and the non-gravitational properties of space permit the mold to remain substantially sag-free during hardening of the filler materials.

Abstract: An endless loop ribbon cassette wherein the storage of a ribbon in a ribbon cassette is effected by a belt assembly which causes the ribbon to move along a generally linear path substantially corresponding to one dimension of a storage cavity. This effects an ordered, rather than a random, storage of a ribbon. In addition, a ribbon is obliquely positioned with respect to a line of print of a printer with which a cassette is to be used.

Abstract: An endotracheal device employing two or three integrated flexible tubes, a relatively large one and one or two smaller ones. One end of the larger tube is positioned in the trachea of a patient, and air or other breathable gas is administered through the other end, which end is external to the patient. One end of one of the smaller tubes is also positioned in the trachea, and this tube extends along the larger tube and terminates, external to the patient, in a puncturable membrane. This membrane is punctured by a hypodermic needle attached to a syringe containing a pharmaceutical fluid, and this fluid is pumped by the syringe through the small tube to the trachea. The fluid then passes into the lungs where it is absorbed into the patient's bloodstream. The second small tube, which is optional, depending upon the size of the endotracheal device, communicates with an inflatable cuff positioned in the trachea which, when inflated, "seals off" the trachea and helps maintain proper device positioning.

Abstract: A printer ribbon cartridge of the type employing two ribbon spools mounted in spaced relation in the cavity formed in the case of the cartridge. In this one, the ribbon is driven by a belt engaging the spools and, in turn, the belt is engaged by both of two alternately driven drive rollers. Alignment and guide devices keep the center lines of the ribbon and belt in coincident alignment and also keep the edges of the ribbon from frictional engagement with the top and bottom of the case.

Abstract: A coin-operated telephone having a housing enclosing a coin acceptor and an associated coin release mechanism which are positioned above a display area. A coin release actuator mechanism is mounted on top of the coin acceptor and includes a rocker arm which is pivoted downwardly by a coin release bar assembly which is secured to and extends across the interior of the housing and is pivoted downwardly by the coin release lever on the front of the housing. The assembly is located above the display area and provides ample clearance in the housing to later add "smart" features while also providing a large display area.

Abstract: A time domain communications system wherein time modulated, impulse derived signals are multiplied by a template signal, integrated, and then demodulated. By this process, usable signals are obtained which would be otherwise obscured by noise.
