Abstract: An enclosed insulator assembly has a generally cylindrical polysiloxane body, a tubular Durethan® core with upper and lower terminals, Multilam™ contacts within the terminals, an arc-quenching tube, and a manually removable handle. Entrance holes in the body accommodate the coupling of external cables to the terminals. A threaded cylinder positioned on the handle's interior accommodates one of an interchangeable cutout fuse tube assembly and disconnect tube assembly and permits the assembly to be inserted into the core as the handle is positioned on the body. Both assemblies have top and bottom fittings with O-rings that prevent weather corrosion between the fittings and terminals. A grooved load interrupter is attached to the bottom fitting of the assemblies to suppress arcing when the assembly is pulled out from the body.
Abstract: A catheter is disclosed comprising a first generally tubular body segment formed about a generally first longitudinally-extending axis and having an outer diameter of no more than approximately 5 fr; and a second generally tubular body segment formed about a second axis and having an outer diameter of no more than approximately 4 fr, the first and second axes intersecting at an acute angle. Preferably, the catheter additionally includes a third generally tubular body segment formed about a third axis and having an outer diameter of no more than approximately 4 fr, the third axis intersecting the second axis at a second acute angle. Preferably, the sum of the two intersection angles is approximately 90°. In addition, the intersection angle of the first and second axes is preferably in the range of approximately 30°.
Abstract: An automatic turn-off switch responsive to displacement of a movable element placed on a seat which resides on the top of a chute located with an opening at the bottom immediately adjacent to a pivotal lever. A spring-loaded latch is normally biased in a contracted condition. An automatic release is cooperatively carried between the spring latch and the lever whereby displacement of the mechanical movable element causes the release to disconnect from the contracted latch, whereby the latch is released for forcible engagement with a conventional on/off switch in a circuit breaker box. When the circuit breaker switch is in the “on” position, the released latch engages the switch and causes the switch to move to its “off” position, terminating all electrical communication with the main power source.
Abstract: A kettlebell is disclosed herein having, in its preferred embodiment, a pair of oppositely-facing, generally frustum-shaped weightplates disposed about a first axis that is perpendicular to the axis of its handle. The frustum shape reduces the force of impact against the user's forearm during certain exercise movements. The preferred handle includes places which can be held between the user's thumb and remaining fingers for improved control during other exercise movements.

Abstract: A steam generator for use with a steam bath has a storage tank for holding a quantity of water from which steam is to be made, means for permitting the ingress of water and the egress of steam from the tank, first heating means for controllably maintaining the water at a temperature that is elevated from the ambient temperature but below its boiling point, and second heating means for selectively heating the water from its elevated temperature to produce steam upon demand.

Abstract: An abrasivejet cutting head is disclosed that includes a valve assembly for preventing back-flow to the abrasive hopper of abrasive-laden fluid from the cutting head when the discharge path for the abrasivejet becomes clogged or otherwise blocked. The valve assembly is positioned within the abrasive line to conduct abrasive from the hopper towards the abrasivejet nozzle. The valve assembly further includes a discharge path which is sealed off from the abrasivejet nozzle during normal operation in response to the relatively lower pressure in the abrasive jet nozzle that results from the flowing fluid therein. If the jet path is blocked or competed in a manner that causes a backflow of the abrasive-laden slurry therein, the cessation of low pressure permits the backflowing slurry to exit via the discharge path and bypass the hopper, substantially avoiding the downtime previously required to clean the hopper.
Abstract: A clock with a seemingly gravity-defying time-indicating element adjacent a substantially vertically disposed dial comprises a magnetic guide element positioned behind the dial for movement around the dial as a function of time, and a magnetically responsive time-indicating element such as a metallic-appearing sphere positioned for viewer visibility in front of the dial. The time-indicating element is magnetically coupled to the guide element for movement therewith around the front of the dial in apparent defiance of gravity to indicate the time without becoming decoupled from the guide element.
Abstract: A modular rack for storing objects. Each rack element has forward, rear, and side walls. The rack elements are configured to have a plurality of protrusions and recessions so that the protrusions and recessions of a rack element slideably interlock with complementary recessions and protrusions of other rack elements of generally similar appearance, so that the rack elements may be assembled into a modular rack without the need of tools or external fastening elements.
Abstract: A plurality of individual magnetically-responsive leg-defining bodies are magnetically coupled together through a printed medium such as a photograph, note or other generally similarly shaped object to stably support the medium in a viewed position.
Abstract: A Class-D audio amplifier is disclosed which accepts a digitized audio signal input and drives a load such as a loudspeaker without digital-to-analog conversion. The amplifier preferably comprises (1) means for processing a plurality of digital audio input values to create a plurality of deviation values respectively based on the deviation of the input value's relationship from a previous audio input value, (2) means for producing a carrier signal, (3) modulation means for using the deviation values to responsively modulate the carrier signal by varying the frequency of its waveform inversely with the magnitudes of the deviation values, and (4) filter means operative on the modulated carrier to produce an analog voltage capable of driving the load.
Abstract: A tissue dispenser is disclosed which permits a user to choose from a variety of liquids to be sprayed on a tissue prior to dispensing. To prevent the tissue from dissolving or becomes too wet to handle comfortably, the dispenser folds the tissue into a double layered structure prior to spraying with the selected liquid, and sprays one layer of the two-layer structure just prior to dispensing so that the dry layer can support the paper's shape and enable the user to handle the tissue without tearing it.
