Abstract: A non-intrusive fluid level detector including a single point capacitive sensor mounted on the outside surface of a receptacle such that capacitive principles can be utilized to sense the level of a liquid contained within the receptacle. The sensor assembly is disposed in a substantially fixed position on the exterior wall of the receptacle wherein the dielectric effect of the liquid changes the effective capacitance of the sensing capacitor as the liquid rises and falls within the receptacle. This change in effective capacitance is detected by electronic circuitry included in the detector device. In one embodiment, the fluid level detector is directly mounted to a completely non-conductive receptacle. In another embodiment, the fluid level detector is mounted to a non-conductive window which is an integral part of a receptacle fabricated out of a conductive material.

Abstract: A friction braking mechanism for a merchandise cart or the like for holding objects includes a frame for supporting the container, and a plurality of wheels rotatably supported on the frame. The wheels are supported for rotation relative to the frame about a rotational axis. At least one of the wheels has a thread guard associated therewith and secured against rotation therewith. An arrangement which is continuously operable during rotation of the wheel coacts between the wheel and the thread guard for frictionally retarding rotation of the wheel. An adjustment arrangement is also provided for adjusting the amount by which the rotation of the wheel is frictionally retarded.

Abstract: A portable treatment table comprises a plurality of separate patient support table sections interconnectable for supporting a patient during treatment at a convenient working level above the floor while lying in a generally horizontal position. Each of the table sections includes a cushion assembly with drops for supporting a portion of the patient's body mounted on a frame and a plurality of support legs are pivotally interconnected with the frame for movement between a folded-up position inside the frame for transporting the table sections and a downwardly extended position for supporting the patient during treatment. Connectors are provided for detachably interconnecting the frames of the table sections and a detachable head piece assembly is provided for supporting a patient's head for cervical adjustment while lying on the interconnected table sections. When not in use, the head piece assembly is stowed for transport beneath the cushions of the table sections inside the folded-up legs and frame.

Abstract: A refrigeration system comprised of a walled insulated enclosure is provided with a drive motor having a drive shaft extending therefrom. The drive shaft and drive motor are positioned along the ceiling of the walled enclosure. The drive shaft terminates at a coupling mechanism. A complimentary coupling mechanism is attached to the top of a well-known movable food rack. Thus, when the food rack is stored within the walled enclosure, the coupling mechanism on the food rack mates with and attaches to the complimentary coupling mechanism of the drive shaft. When the drive motor is actuated, the drive shaft will rotate the movable food rack. It will be appreciated that by rotating the movable food rack, the present invention will permit the food stored on the food rack to chill far more quickly than if the food rack were to remain stationary. In addition, by rotating the food rack, the present invention eliminates warm air pockets which allow bacterial growth.

Abstract: A wheel bracket mounting structure which includes an elongated and flexible bracket member having an axle mounting section and a stem mounting section at generally opposite ends thereof. The axle mounting section includes a generally flat, platelike portion. The stem mounting section includes an elongate, generally arcuate stem adapted to be directly attached to a support member on a wheeled vehicle. An intermediate section is provided between the axle mounting section and the stem mounting section. A segment is provided at the juncture between the intermediate section and the flat, platelike portion to provide a region remote from the arcuate stem about which the platelike portion can elastically flex relative to the arcuate stem.

Abstract: A wheel bracket assembly includes two separate, platelike bracket parts which each have a noncircular opening therein and are disposed on opposite sides of a wheel in angular alignment. The ends of the axle for the wheel extend through the noncircular openings and the bracket parts are fixed against axial and rotational movement with respect to the axle. A method of making the wheel bracket assembly includes the steps of stamping out from at least one metal plate the two bracket parts which are substantially mirror images of each other and have the noncircular opening therethrough, placing the bracket parts in angular alignment on opposite sides of the wheel so that the ends of the axle extend through the noncircular openings, and upsetting each end of the axle to retain the bracket parts in place and so that the material of the axle flows to fill the noncircular openings in the bracket parts and thereby prevent relative rotation of the bracket parts.

Abstract: A cluster assembly for application to a three prong header from the interior of a hermetically-sealed compressor. The cluster assembly includes an insulated block having spaced parallel passages in which connector clips with leads attached are disposed. The block has flanges at the ends of the passageways from which the leads project, the flanges having notches. The leads are placed in the notches and are twisted to lie outside the surfaces of the block, the block when applied spacing the leads away from the compressor housing.

Abstract: A cluster assembly wherein a block has three longitudinal passageways. Connector clips are inserted into those passageways. The block has transverse holes in a front wall providing a communication to the clips so that pins from a header can pass through the holes and be connected to the clips. One of those holes has a boss surrounding it to improve the assembly of the cluster assembly to the three-pin header.

Abstract: A cluster assembly having a block and connector clips disposed within passageways in the block. Locking tabs pivotally mounted in the block and integral therewith drop into the receptacles forming part of the clips to hold the clips within the block.

Abstract: A microcoil having a winding on a composite core made up of a portion of substantially magnetic material and a portion of substantially non-magnetic material. The winding is split so that a part of the magnetic material core portion is exposed, and a laser is used to remove material from the exposed part of the magnetic core portion. The inductance of the coil is measured during the removal of the magnetic material, and the inductance of the coil is trimmed to a desired value through the removal of an appropriate amount of magnetic material. The non-magnetic core portion serves as a support structure for the portions of the winding on the core even if a substantial portion of the magnetic material is removed.

Abstract: A coil assembly having a core and a winding on the core, wherein a contact element electrically connected to the winding is both mechanically clamped and bonded to the core. In an exemplary microcoil assembly having a C-core, a generally U-shaped contact element is bonded to each foot of the core by epoxy and mechanically clamped to the core foot to hold the contact element in position while the epoxy cures. One end of the coil winding is soldered to one of the contact elements and the other end of the winding is soldered to the other contact element. The coil assembly is subsequently soldered onto a printed circuit board. Each contact element may include a pin portion to be inserted into a printed circuit board.
