Filed:

Aug 23, 1996

Appl. No.:

8/701872

Inventors:

Richard D. Keller - Takoma Park MD

International Classification:

F16B 208

US Classification:

403384

Abstract:

An interruptible connector assembly adapted for the interlocking spatially of one tubular member with another object to be supported thereby, comprising: flexible clamp band adapted to be deformed into a U-shape and overlap any underlying planar surfaces; a two-component, rigid support means, with each structurally identical component, and having an at least partially arcuate proximal one end, such opposing arcuate surfaces adapted to nest a tubular member; a linear bore hole traversing of each of said clamping components; spherically faced cylindrical bushings, to slidingly engage the bore hole of its associated clamping component and each having at its shoulder contacting the adjacent support means; an elongate, assembly fastener means to slidingly traverse the aligned assembly via the component bore holes, being of a length sufficient to extend from one external side of the assembly to the other external side about the interlocked two tubings in a variable angle juxtaposition. In a second embodiment, two of the above-described clamps are conjoined axially to interconnect two tubular members in any one of several angles. In another embodiment, the elongate bolt is provided with an integral fixed collar projecting radically and located proximal to one longitudinal end, serving as a retaining wall for end-mounted accessories.

Abstract:

The disclosure relates to an optogalvanic intracavity detector and method for its use. Measurement is made of the amount of light absorbed by atoms, small molecules and ions in a laser cavity utilizing laser-produced changes in plasmas containing the same atoms, molecules, or ions.

Appl. No.:

8/381565

Inventors:

Richard D. Keller - Takoma Park MD

International Classification:

A61M 5178

US Classification:

604438

Abstract:

A squeeze-activated fluid applicator for human manipulation is provided to express the medicinal contents of rupturable capsules; the devise consisting of a shell-like, elongate member of uniform diameter adapted to receive slidingly at its proximal open end an elongate cylindrical member. A cantilever member is adapted to be pivotally mounted midway of the inner elongate member, with a vertical piston operatively connected to the cantilever proximal end, while a strong upward spring bias is provided on the cantilever distal end. A push rod located axially of the cylindrical member can be hand activated to dislodge a bias-arrest feature on the cantilever and to cause the piston to close into a proximal face capsule chamber of the cylindrical member, compressing and expressing the enclosed contents into an adjacent port.

International Classification:

A63B 5700

US Classification:

473386

Abstract:

A portable device for non-stooping placement of golf balls and golf tees on site comprising an elongated tubular shaft with specially modified ends. The lower shaft end has a golf ball holding pincers and an adjacent dual tine, fork-like tee holding socket and tee retrieving device. The upper shaft end comprises a biased trigger mechanism cantilevered to actuate the upper end of an elongate solid rod disposed slideably within the shaft, and with the rod lower end adapted to carry a horizontal flange which reciprocates between the tee clamping position and a tee supporting position. The device is adapted for sequentially setting a tee in the desired ground and then placing the golf ball on the spotted tee while the golfer remains in a standing position throughout. More broadly, there is provided a dissimilar objects grasping and placement device having a hand gripping and actuating longitudinal first end and oppositely extended object grasping second end, which provides for alternate loading and placement of unlike objects such as driving tee and golf ball.

International Classification:

US Classification:

Abstract:

A pair of upwardly projecting, readily displaceable, push-up handles which are selectively mountable on the lateral bars of a wheelchair framework. The handle mounting means for each side includes a tubular member that is fixed between the upper and lower rigid frame members of the wheelchair via a pair of dual U-ring interconnecting bracket means which secures the first tubular member to the frame members in a variable inclined position mode. A second tubular member of an outer diameter somewhat reduced and is adapted at its one longitudinal end to engage telescopically the open upper longitudinal end of the first member. At the upper longitudinal end of the second member is optionally located, a replaceable resilient gripping means. The second tubular member is retained within the first member by a tensioned cord means located inwardly and longitudinally of the conjoined members, which cord is sized to require elongation sufficiently to bias the engaged members into a secure interconnecting relation while serving as a set of push-up bars for the seated invalid. The cord-induced tube engagement bias can be readily overcome by manual effort to be displaced from the telescopic connection and to hang freely along the wheelchair lateral framework.

US Classification:

403384

Abstract:

An interruptible connector assembly adapted for the interlocking spatially of one tubular member with another object to be supported thereby, comprising: flexible clamping members adapted to be deformed into a U-shape and overlap any underlying planar surfaces; a single component, rigid support means, with each and having a proximal structurally identical arcuate component each end, such opposing arcuate surfaces adapted to nest a tubular member; a linear bore hole traversing of each of said gripping components; spherically faced cylindrical bushings, to slidingly engage the bore hole of its associated gripping component and each having at its shoulder contacting the adjacent support means; an elongate, assembly fastener means to slidingly traverse the aligned assembly via the component bore holes, being of a length sufficient to extend from one external side of the assembly to the other external side about the interlocked tubings. In a second embodiment, two of the above-described clamps are conjoined axially to interconnect two or more tubular members in any one of several angles. In both embodiments, the elongate bolt is provided with an integral collar projecting radially and located proximal to one longitudinal end, serving as a retaining wall for end-mounted accessories.
