Abstract: Improved articulation structure is provided for pivoting links of a modular belt, namely a hinge strip of flexible material such as a thermoplastic elastomer and mating receptacle aperture slots in link ends. The modular links are all alike with flared ends in the slots permitting the hinge strip to flex a limited angle without frictional rubbing with the links. The slots have limited constant widths facing outwardly to prevent movement of the hinge strip in a direction perpendicular to the surface of the belt. Staggered end fingers of the links are half the thickness of a central body portion which provides a smooth top surface without apertures for interdigitation with similar end to end links. This construction is particularly useful for operation in abrasive conditions where wear on conventional pivot pins would significantly reduce belt life.

Abstract: An organization wherein panels are secured by sewing or other mechanical or adhesive fasteners to define a pyramidal construction, with an opening at its upper end to receive a shank of a jewelry member such as an earring therethrough, the clasp extending above the pyramidal construction. A forward panel member is mounted to the pyramidal construction. The organization may be further applied to covering for necklace and ring construction, wherein the cover panel is utilized as a covering for a ring or necklace construction. An alternative jewelry apparatus is defined by at least one clip member associated for each year of an individual, wherein the clip member is defined by a frontal panel of a generally diamond shaped configuration and a complementarily configured rear panel of a like configuration. Elongate "L" shaped portions defining ears are directed upwardly from an upper apex of the frontal panel, with the frontal panel defining a simulation of a rabbit-like visage.

Abstract: An infant restraint device is provided for securing and supporting an infant inside a motor vehicle. The device includes a shell assembly having upper and lower shell portions pivotally coupled together. The upper shell portion can be positioned in either a first generally planar orientation or in a second angular orientation with respect to the lower shell portion. A locking mechanism is provided for securing the upper and lower shell portions together in either the first or second orientations. In the first generally planar orientation, the device provides a car bed for the infant. In the second angular orientation, the device provides a standard rear-facing infant seat. A collapsible lower support surface provides a seat for the infant when the device is in the angular orientation. The lower support surface bends along a flexible portion when the upper shell portion of the device moves to the planar orientation to provide a generally planar support surface for the infant.

Abstract: A method and apparatus for invisibly setting round diamonds is disclosed. The diamonds are provided with grooves cut in the pavilion below the girdle of the diamond, and a round barrel is provided which has ridges projecting inwardly from the inner wall of the barrel. The diamond is rotated into the barrel to interlock the ridges within the grooves formed in the diamond to hold the barrel and diamond securely together. The barrel is formed of deformable metal which itself is hammered thereby further preventing relative rotation between the diamond and barrel and ensuring the diamond is securely set within the barrel.

Abstract: A gurney, or hospital cart, is disclosed that is characterized as being made predominantly of materials that are non-metallic, non magnetic, and of low electrical conductivity. Such a feature is of particular importance in those health care facilities wherein modern non-invasive body scanning equipment is in use, such equipment as provides imaging based on NMR, MRI, and the like, especially wherein large-scale superconducting magnets are in use.

Abstract: A bed is provided with a frame (2, 102) and a keyboard-shaped resting surface (3, 103) comprising a series of mutually independent transverse adjacent removable elements (5, 105, 205) which are vertically mobile independently of each other. This movement is produced by hydraulic cylinder-piston units, manually or motor-operated articulated parallelogram systems (270), or equivalent systems.

Abstract: A light weight, collapsible, full-size cot with telescoping side rails permanently attached within sleeves at each side of the fabric top, and transverse leg assemblies which support and push apart the side rails by a finely controlled pivoting action to stretch the fabric top to the particular degree of tautness suitable to each cot user.

Abstract: A boot shaped pillow for use by a mother or some other person to aid in feeding an infant. The pillow is intended to rest on the person's lap and curve around his or her abdomen while the person is seated. The person rests his or her arm on the pillow and with the same arm supports the infant for an optimal feeding position. The pillow is made of a plurality of layers which together provide a constant firmness and machine washability.

Abstract: Sitting or reclining furniture with an upper and a lower part that can move relative to each other. The upper part is suspended so as to be able to oscillate on the lower part and at least two sets of ropes are arranged functionally in series. One set of ropes is suspended by way of bridge pieces and an approximately gallows-like frame. The bridge pieces are, in turn, joined to each other through the frame.

Abstract: A seat cushion comprising an upper foamed layer of low impact resilience having a ratio of not higher than 25% which exhibits high hysteresis loss and at least one foamed layer supporting said upper layer of higher impact resilience as well as a method for producing the same.

Abstract: An apparatus for patient elevation above a fluidized surface includes a web of filter sheet material disposed beneath the patient and between the patient and the main filter sheet that covers the fluidized surface. The web is loosely mounted about a pair of support rods which are connected via a pair of splice bar linkages to a pair of dual acting hydraulic cylinders. Activation of the cylinders causes the two rods to separate from one another. The separation takes up the slack in the web and renders it taut about the two support rods. Further activation of the cylinders elevates the two support rods above the fluidized surface by pivoting them through the splice bar linkages. This raises the web and the patient supported on the web. A solenoid valve is provided in the hydraulic circuit to enable rapid lowering of the support rods and the web when an emergency procedure such as CPR must be administered to the patient.

Each chain plate includes a straight waist portion disposed between two semi-circular end portions, an inner face formed with an incline extending along an edge thereof, and a blade portion merging with the incline at the straight waist portion. The first outer chain plate includes a transverse dimension greater than that of the second outer chain plate, while the first inner chain plate includes a transverse dimension greater than that of the second inner chain plate.

Foot rest means, leg support means, and a vertically elevated trunk support means are provided to support the weight of the person being carried in the forwardly leaning position with his center of gravity positioned substantially over the rotational axis of the wheels.

Abstract: A signalling device for attachment to a rural type mailbox mounted on the side of a road for alerting the owner of the mailbox that mail has been deposited therein by the mail carrier. The signalling device includes a flag plate pivotally secured to either the mailbox or a support post which is actuated by the opening of the door of the mailbox to cause the flag plate to fall, due to gravity, from a raised, non-signalling, position to a lowered, signalling, position. After the mail is removed from the mailbox, the flag plate is easily raised to reset the signalling device in its raised, non-signalling, position to be reactuated by the mail carrier when he next delivers the mail.
