Abstract: A superconducting wire is produced by the surrounding of a superconductive material core with an intermediate compressible insulating layer and an outer malleable layer and then drawing said composite structure through a series of dies to reduce the diameter of the wire on the order of 400 to 10,000 times or by reducing the superconductive core material to the desired wire size by passing it through a series of dies to reduce the diameter of the wire on the order of 400 to 10,000 times and then coating the wire with a noncompressible insulating layer and then placing an outer malleable layer over the insulated wire and drawing this through dies to snuggly fit the outer layer onto the insulated wire. This wire's superconducting characteristics are not intended for carrying high levels of currents so the reduction of the available current carrying cross section by the introduction of the insulating layer is not of concern in the applications for the wire.

Abstract: A chart recorder is described for recording parameters such as temperature and humidity on rotating planar charts. Pens, which are used to form traces on a chart as this is rotated, are moved by pen actuators along travel paths that are parallel to a straight radius relative to the axis of chart rotation. The pen actuators are electrically moved under the control of a microprocessor to positions as determined by representative of parameter values. Various mechanical and electrical control features are described whereby pen motions are caused intermittently so as to preserve battery power and achieve long term portable operation.

Abstract: A collapsible box-like container of the type constructed to fold flat for storage and shipping, is provided with a reverse integral hinge portion which is positioned to lie in abutting parallel relation with a second integral hinge on the opposite side of a third integral hinge portion when the container is folded flat; the reverse hinge and the second hinge may be displaced simultaneously in nested relationship to define an exterior angle at the reverse hinge which is substantially congruent with the interior angle formed at said second hinge. This construction permits the effective width of the flattened container to be reduced for shipment by folding into a right angle shape so that it conforms to the exterior configuration of another object such as a book or a separate, rigid box, for example.

Abstract: Test meters, particularly of the type employed for testing electrical circuits, e.g. multimeters, are improved in operational efficiency. In one aspect, remote selection of test and/or report format frees the operators hands for concentration on a test piece. In another test results or format information are conveyed as synthesized speech in any of a number of selectable formats. By combining both aspects in a hand-held multimeter, a high degree of interaction between the operator and the meter is achieved.

Abstract: The invention presented is an adjustable mounting clip for a thermocouple assembly comprising a deformable element having a helically wound first portion and a second portion which defines a relatively flat segment, substantially perpendicular to the central axis of the helically wound first portion and capable of supporting a thermocouple terminal block in a thermocouple assembly. Also presented is a thermocouple assembly comprising such mounting clip.

Abstract: The present invention relates to a rapid response thermocouple probe 10 having a resilient, replaceable thermocouple element 50 probe 10, comprising cylindrical body 20 having housing means 30 at one end, securing means 40 associated with housing means 30 and comprising two securing elements, 40a and 40b, in electrical isolation from each other, and a resilient thermocouple element 50 comprising an arcuate strip of two dissimilar metals joined together, ends, 55 and 57, of thermocouple element 50 being removably secured to securing means 40. The thermocouple probe of this invention eliminates the necessity of discarding the entire probe upon wear or breakage of thermocouple element 50.

Abstract: A universal connector for polarized thermocouple leads and the like wherein a single connector replaces previously required multiple connectors and necessary adaptors. The universal connector is capable of receiving both standard-sized and smaller or miniature-sized male connectors, with resultant savings in parts and manipulative labor.

Abstract: The object of this invention is to provide a rapid response thermocouple which is removably affixable to the surface whose temperature is to be measured, and a method of making such a thermocouple. The thermocouple of this invention comprises a thermocouple assembly 24, a first film 10 having an adhesive coating on one side, a second film 50 having an adhesive coating on both sides, a third film 30 and a tab 40, wherein the adhesive coated side of the first film is adhered to one of the adhesive-coated sides of the second film with the thermocouple assembly interposed between them, and further wherein the third film is removably adhered to the remaining adhesive-coated side of the second film with the tab disposed between them so that it partially extends beyond the edges of the second and third films to facilitate removal of the third film from the second film.

Abstract: Several forms of a novel amplitude-modulated (AM) signal format are disclosed. Circuits of several types for generating the desired special vestigial-sideband (SVSB) AM waveforms are discussed. The principal form of the SVSB modulation provides for a reduction in transmitted signal bandwidth compared with standard double-sideband techniques plus very linear amplitude characteristics with simple synchronous detectors. Circuits according to the invention may also include means for dynamically varying signal bandwidth to accommodate special applications.

Abstract: Several circuit detectors and noise reduction networks with circuit detectors are disclosed. Detectors and networks according to the invention generally include a discharge diode placed within a feedback loop of an operational amplifier so that the hold time of the system is unaffected by the detector level. Circuits according to the invention may also include a conductor to provide a dynamically controlled charge and/or discharge path in combination with an active signal amplifying device.

Abstract: 0.degree.COLD JUNCTION COMPENSATOR PROVIDES THE ELECTRICAL EQUIVALENT OF AN ICE-BATH REFERENCE THERMOCOUPLE, AT A SELECTED TEMPERATURE, FOR EXAMPLE O.degree. C. Input connectors, for engagement with conventional thermocouple units, form thermocouple junctions with conductors connected to a battery-operated Wheatstone bridge circuit adapted to supply an equal and opposite voltage output compensating for variations in the thermocouple junction output at different ambient temperatures. The compensator may be included in a module having input sockets or input plugs to coact with plugs or sockets of conventional thermocouple units. The compensator and battery may be encapsulated, or an accessible switch may be included in the battery circuit.
