Abstract: The disclosure sets forth a different annular link as the building element; instead of using a split annular link of a 3:1 ratio of link inner diameter to major wire diameter, the link has substantially thinner annulus for forming the rope chain, an annulus that requires an over 5:1 ratio of inner annulus diameter to major wire diameter. The presently preferred ratio is between 5.2 and 5.7:1. It is possible to use even thinner annuluses, i.e. having greater ratios, e.g., 7.2-7.7:1 with even greater weight savings (approximately 35%), or other even greater odd-numbered ratios of inner annulus diameter to major wire diameter (e.g. 9.4-9.9:1). Thus, while there is no theoretical limit, there is probably a maximum practical upper limit to the ratio of inner annulus diameter to major wire diamater.

Abstract: A device for enabling testing of a person's physical condition, by enabling easurement of the energy expended by the person to be tested thereby, in manually maintaining rotation of a flywheel in a stationary bicycle, against resistance applied to the flywheel, for use in determining the efficiency of the person's body in using energy, as an indication of such person's physical condition.The device is adapted to overcome inertia of the flywheel, from rest to a selected speed of rotation thereof, in an efficient and effective manner, prior to the onset of the test. Upon the onset of the test, with inertia in the flywheel having been non-manually overcome, the person to be tested is to manually maintain rotation of the flywheel, against resistance applied thereto, by manually rotating pedals operably connected to the flywheel.The device includes a non-manual inertia overcoming mechanism.

Abstract: A remote actuator means for a pressure-switch operated device such as a conventional latching relay acting as as on-off switch for an electric motor is provided which comprises a remote spring-loaded actuator cap connected to the device to be actuated via an air actuator conduit. The air actuator conduit communicates with the atmosphere through a vent provided only in the actuator cap. When the operator manually depresses the actuator cap, he or she will automatically cover the vent opening, causing the heretofore open system to be temporarily closed. As the actuator cap is depressed, it compresses air within the now temporarily closed system, causing the latching relay to be "pulsed", which, in turn, activates or deactivates whatever the relay is electrically connected to, e.g., an electric motor driving a water pump in a whirlpool bath system.

Abstract: A device for enabling detecting of the time code word prerecorded on each frame of videotape, for use in videotape production functions. The device is adapted to enable locking onto time code input signal frequencies rapidly and efficiently over a wide range of videotape running speeds. It is further adapted to enable detecting of errors in the time code input signal efficiently and effectively. The device includes an input signal frequency locking circuit, including at least one phase lock loop, responsive rapidly over a wide range of videotape running speeds for enabling decoding of difficult-to-read time code, and for generating the circuit clock frequency. The device further includes a valid sync word detecting circuit, including a counter, and a pulse counting circuit, including at least one counter, for detecting error in the time code signal and preventing loading of invalid time code.

Abstract: The invention comprises a urethane-coated polyethylene terephthalate mesh bone induction tray, with a simulated condyle integrally affixed to the mesh tray without the use of metal pins, screws and the like. The invention lies in the integral affixing of a urethane plastic, e.g. polyether urethane simulated condyle to the end portion of a plastic mesh tray. The simulated condyle may be customized, i.e., premeasured for a particular patient before the operation, or may be custom-contoured from one of several pre-formed condyle/tray combinations having varying shapes or geometries. The condyle portion is further preferably reinforced with a core of stainless steel wire, e.g., a Kirschner rod or wire, running the length of the condyle portion and projecting beyond, into the tray, to permit embedding of the wire into the remaining osseous structure, thus anchoring the entire combination.

Abstract: A fluid atomizer or "air mist" nozzle or valve of this invention has an elongated nozzle body provided with a frontal exit port, a needle valve coaxially moveable therein and normally biased against a spring means so that its outlet end is just upstream of the nozzle exit port. The nozzle body is connected to a source of both water and air, as in the prior art. In this invention, the needle valve outlet position is controlled, vis-a-vis the nozzle body exit port, from the front of the fluid nozzle by providing a frontal control means for moving the nozzle body with respect to a fixed-in-place needle valve. The frontal control means is provided with both a rotatable and an axial motion and comprises preferably a control knob or ring threadably engaging the nozzle body near the frontal end thereof. The control knob is, in turn, mounted within a fixed flange plate, having a rearwardly extending cylindrical bore, for slideable axial movement within said cylindrical bore.

Abstract: A transparent laboratory slide for wet mount microscopic examination. A base member is formed with discrete platform surfaces or slide plates over which a cover slip is removably positioned. The fluid specimen to be examined is retained in the thin space between the platform surface and the cover slip by a capillary action. Peg and socket interconnecting means provide precise spacing between the platform and the cover slip. The platform surface is raised from the bottom wall of the base and the sides of the platform are opened to the external environment. This slide conveniently provides for low power and high power magnification as well as increased magnification by means of oil immersion.

Abstract: Improved apparatus and method for the electrodeposition of aluminum and its alloys using aprotic, oxygen and water-free organoaluminum electrolytes, involving a method for removing water from pretreated workpieces and locating them in a plating barrel without exposure of workpieces to air, and further utilizing a rotatable, triple-chambered treatment barrel which provides a greater ratio of anode to cathode surface area and also decreased spacing between anode and cathode, and further applying centrifugal force to the treatment barrel to assist the draining and removal of electroplating and rinse solvents.

The system is particularly adapted for use in the elections process, with the code comprising a bar code, representing an identifier assigned to the person identified, which identifier is random relative to an alphabetical listing of persons so identified.The system includes a laser printer, microprocessor-based, operable in response to a laser control program, for printing the bar code associated with the particular person at the appropriate location on the form.The system further includes a portable compact reader, microprocessor-based, which includes a wand adapted to sense the bar code on the form. The reader is operable in response to control by the operator, and to a reader control program, for reading the bar code, to generate data relating to the person identified thereby for processing thereof.

Abstract: This invention relates to a highly accurate, rapid and simple estimation of thyroxine (T.sub.4) directly from blood serum and also relates to the accurate measurement of triiodo-L-thyronine (T.sub.3) directly from blood serum. More specifically, the invention relates to a rapid, specific and reliable radioimmunoassay (RIA) technique for measurement of both T.sub.4 and T.sub.3 in unextracted serum. The method requires very small amounts of serum, e.g., 25 microliters (.mu.l) to measure T.sub.4 concentration in nearly all specimens representing clinical states of eu-, hypo- and hyperthyroidism, and 250 .mu.l to measure T.sub.3 concentrations in specimens representing most clinical states.
