Abstract: A foldable cart including a plurality of vertically spaced pairs of shelf members, their outer ends being pivotally connected to a pair of end frames, a lift bar pivotally connected to the inner ends of the shelf members and linked to the end frames for collapsing the shelf members and end frames to an inoperative folded position, and a stop member associated with the lift bar for limiting the downward movement of the lift bar when the pairs of shelf members are in a horizontal, coplanar operative position.

Abstract: An apparatus for forming a dome in the bottom wall of a can body having a beveled peripheral edge incorporating a floating doming die and pressure ring to compensate for misalignment of the doming die and punch or the can body, and resilient members for restoring the doming die and pressure ring accurately to a normal coaxial central position.

Abstract: A deck member for a storage rack in which the front and rear portions of the deck member are provided with the front and rear planar platform surfaces including corresponding upwardly projecting transverse front and rear ridge mebers having a front-to-rear spacing slightly greater than the front-to-rear dimension of a storage container received on the deck member, to retain the storage container upon the deck member.

Abstract: An ash disposal device having an elongated base member with a top sweep surface mounted transversely along the front of and flush with the floor of a fireplace, an ash opening through the sweep surface communicating with a depending ash chute below the base member, and a lid member hinged to the base member for opening and closing the sweep surface and the ash opening.

Abstract: An expansible baby gate having a main lazy-tong barrier formed of intersecting and pivotally connected first and second main slats which form V-shaped openings between the slats along the top edge portion of the barrier. A supplementary upper barrier, including a plurality of shorter auxiliary slats pivotally connected to each other and to the main slats for occluding the V-shaped openings in the top edge portion of the main barrier.

Abstract: A method and apparatus for vulcanizing a rubber repair patch on a tire incorporating an internal fluid pressure bag placed within the interior of the tire and against the patch, an inflatable mandrel within the tire and against the internal bag, an external fluid pressure bag engaging the exterior of the tire radially opposite the internal bag, and a retainer device, such as a retainer strap radially encircling and engaging the external bag and the mandrel to cause the internal and external bags to be forced toward each other to squeeze the patch and tire between them, upon inflation of the mandrel.This invention is paticularly characterized in utilizing internal and external fluid pressure bags having walls of two-dimensional flexibility and utilizing a heat-conductive hydraulic fluid within both bags having a boiling point greater than the vulcanizing temperature.

Abstract: A hollow thermoplastic unitary, parallelepiped receptacle having open front and back faces, closed side walls, one closed end wall, and an open end including a hinged closure member for receiving a conventional elongated rectangular compact disc container having a compartment in one end portion of the container receiving a rectangular storage box containing a compact disc. The receptacle includes a pair of transverse rib members in its back face for transverse alignment with the interior transverse edge of the compact disc storage box when the container is inserted either right-side-up or upside down into its operative position within the receptacle.

Abstract: Selective non-magentic detection of non-ferrous metallic particles in a mixture of same with ferrous metallic particles and non-metallic particles derived from homogenized and magnetically treated municipal or like waste by a plurality of electronic detectors and separation of a non-ferrous metallic concentrate from said mixture.

Abstract: A continuous soil mixing apparatus including a series of soil feed hoppers and a mixing chamber, all supported over an elongated, endless, single conveyor belt to carry layers of soil of different compositions from the different feed hoppers to the mixing chamber. The first soil hopper remote from the mixing chamber incorporates a soil agitator and deposits its soil directly upon the conveyor belt, while the remaining hoppers incorporate independent feed belts above the conveyor belt.

Abstract: A holder for a yarn package or yarn carrier including a support member to which is fixed a clamp member having a bottom jaw surface and a bell crank member pivotally supported upon the support member below the clamp member, so that the rearward and upward projecting leg of the bell crank member constitutes a pivotal clamp member for clamping the lip of the yarn carrier against the fixed clamp member and the longer, forward projecting lever arm leg of the bell crank member provides a support for the interior of the yarn carrier.

Abstract: A stringed musical instrument of a resonator guitar type, including an elongated, substantially horizontal, hollow body supporting pegs, a fret board, and a resonator in which each of the string members includes an elongated string, an elongated rigid string bar and a string cable, connected end-to-end. The strings extend over and lightly engage a transverse bridge, while the rigid string bars bear against a transverse support rod adjacent the bridge. The cables are connected to tuning lever members independently pivotally mounted upon a transverse tuning shaft at the tail end of the body. Operative members, such as pedals and/or knee levers are connected by linkages to the tuning lever members for controlling the tension in the strings.
