Abstract: A nail holder for hammers is clipped to a hammer beneath the hammer head and includes a pair of juxtaposed, generally coextensive cantilever members of spring material having overlapping free ends which are located adjacent the hammer head and are resiliently biased toward one another to clamp the head of a nail gently between the free ends, with the shank of the nail projecting generally perpendicular to the cantilever members, in position for starting the nail, especially in relatively soft materials, the free ends facilitating freedom of movement of the free ends and selective release of the nail head from between the free ends subsequent to starting of the nail without disturbing the started purchase of the nail.

Abstract: A system and method for controlling a refrigeration unit of an air conditioning system operating in connection with a given building environment so as to establish conditions providing a desired comfort level within the building environment, the system and method being arranged to detect the output of the refrigeration unit, to detect changes in interior or exterior conditions which will affect the comfort level in the building environment and to provide at least one control signal in response to the detected output and conditions for operating the refrigeration unit, the control signal being compensated for the predetermined dynamic characteristics of the particular refrigeration unit and the predetermined dynamic characteristics of the particular building environment such that the control signal will anticipate further change in the conditions within the building environment and will operate the refrigeration unit so as to counter the anticipated further change and tend to maintain the desired comfort level

Abstract: An attachment for a flying disk toy has a plurality of cantilevered radial vanes for extending over the upper surface of the disk toy and flexing toward and away from the upper surface in fluttering movements during flight to produce a distinctive sound, an aesthetically appealing appearance and an undulating flight path.

Abstract: A quiver includes a frame releasably holding arrows and mounted on a bow for movement between a storage position, in which the arrows are disposed parallel to the bow, and a nocking position, in which the arrows are placed across the bow and the bowstring thereof. The frame carries a drive member which extends axially at an acute angle to the bow, and the drive member is driven by an actuator through simultaneous axial and rotational motion to move the frame from the storage position to the nocking position.

Abstract: A method of making a drill bushing or a similar article, such as a pump seal, the method including metallurgically bonding tungsten carbide within a matrix to the steel blank by treating the combination in a vacuum, hydrogen, salt bath or other heating medium, making a suitable central opening, where required, in the tungsten carbide, heat treating and finishing the piece to the proper dimensions.The method of making such articles also includes metallurgically bonding tungsten carbide particles within a matrix which is also metallurgically bonded to a steel body, making a suitable opening, where necessary, leaving a thin coating of matrixed tungsten carbide to improve resistance to wear, heat and corrosion and then finishing the piece to the proper dimensions.The method may include metallurgically bonding tungsten carbide particles within a matrix bonded to a steel body while under the influence of forces tending to eliminate voids in the completed coating of matrixed tungsten carbide.

Abstract: A surgical scrub system used in an operating room for dispensing any selected one of a plurality of sterile liquids and applying the selected liquid to an area of the body of a patient while maintaining the sterile condition desired at that area, the scrub system including a scrub device constructed primarily of sterilizable materials and a dispensing arrangement to which the scrub device may be aseptically coupled for transfer of the selected liquid to the scrub device.

Abstract: A pallet for supporting product capable of being moved by means of a fork lift truck or similar unit having at least two runners and a plurality of deck boards or stringers, the deck boards being dadoed into the runners, at least a portion of the inner edge of each of the outermost deck boards being thinner than the full thickness of the deck board, the corresponding runner adjacent the thinner portion of the deck board being undercut complementary thereto to receive the deck board in intimate contact to thereby strengthen the pallet.

Abstract: A latch having a multiple function prevailing-torque mechanism which facilitates engagement and disengagement of the drawbolt and the strike of the latch and provides a simplified construction enabling ease of assembly and adjustment, with the prevailing-torque mechanism serving to retain the component parts in assembled arrangement and in appropriate adjustment. A further latch arrangement includes a positive lock which serves to retain the actuating lever of the latch in a stowed or latched location.

Abstract: A hamper for collecting items, such as soiled laundry, includes a cylindrical receptacle wall having a reception entrance at the top and a delivery port at the side, the delivery port being selectively opened or closed by a cylindrical sleeve which overlies the receptacle wall and can be rotated relative thereto, and a liner within the receptacle for receiving the items placed therein through the reception entrance and for being withdrawn through the delivery port, when the sleeve is rotated to open the delivery port.

Abstract: A display is mounted on a wall at a selected distance from the wall by means of a spacer erected from a sheet of material, which normally is flat for storage and transportation, into a partially tubular member of selected axial length which is secured at one end thereof to the display and bears against the wall at the other end to space the display away from the wall. The spacer is included in a kit having a mounting board with an obverse surface receiving the item to be displayed and a reverse surface for receiving the one end of the tubular member.

Abstract: Apparatus for receiving a stack of case blank sheets from a source of supply and delivering the sheets in shingled arrangement, for further processing, by receiving the stack at a first level, elevating the stack intact vertically to a second level above the first level, where the stack is transferred to a feeder located at the second level for operation in association with a stripper to feed the sheets forward in shingled arrangement from the bottom of the stack, while stabilizing the stack against toppling backward during feeding of the sheets forward from the bottom of the stack.

Abstract: An electroplating rack upon which an item to be plated is secured for immersion in a plating solution and in which electrical contact is made between the rack and the item by a clamp having a clamp screw and an opposed clamp pad, both the clamp screw and the clamp pad having a structure which provides the appropriate clamping forces and electrical connections while establishing seals for isolating the electrically conductive elements of the clamp from the plating solution.

Abstract: A cross-head die in which the manifold is provided with means for selectively varying the volume of the manifold at some locations relative to other locations, whereby the relative wall thickness about the annular configuration of the material flowing through the die is selectively adjusted about the periphery of the annular configuration of flowing material. Wall thickness and configuration are further controlled at the outlet orifice of the die by means movable to selectively expand, contract and alter the annular configuration of the die passage at the orifice.

Abstract: A drill bushing or similar article, such as a pump seal, having a hardened body of steel and a thin coating of tungsten carbide distributed throughout a matrix of nickel chrome which provides a metallurgical bond to the steel body and a metallic bond to the particles of tungsten carbide. The drill bushing or similar article will have the wear characteristic of the solid tungsten carbide article, but would retain the coefficient of expansion characteristic of steel with the steel body eliminating the brittleness experienced in solid tungsten carbide articles.
