Abstract: A simple and effective means for improving mechanical resistance to stress at the coupling between a conductor and the connector is provided in a thermocouple connector which includes an integrally attached spool for storing in neat, compact and readily accessible form, the excess length of electrical conductor which is attached to the connector while providing the resistance to the stress.

Abstract: An assembly for accurately and easily positioning and aligning a sensor device relative to a fluid flow stream in a pipe, incorporates a threaded housing which is engageable with a standard pipe tee-fitting to provide a platform for linearly positioning the sensor relative to the axis of flow. A sensor unit subassembly is rotatably supported on the platform so that it may be rotated into proper radial alignment with the flow axis while it is supported on the platform at the proper linear position relative to the flow axis. A paddlewheel flowmeter having a single leg supporting the paddlewheel axle in cantilever fashion forms the sensing unit which exploits the improved alignment accuracy of this assembly to avoid build-up of sludge and debris which might affect free rotation of the paddlewheel. Separate and independent lock-nuts fix the housing in position relative to the tee-fitting, and fix the sensor sub-assembly in position relative to the housing.
Abstract: Collapsible box-like cartons of the type constructed to fold flat for storage and to be unfolded to form a rigid carton for shipping purposes are provided with secondary hinge and removable sections which thereby enable such cartons to be transformed from their first substantially rectangular geometric shape in which they are used as shipping cartons to a second useable shape so that they can be recycled for other purposes.
Abstract: An improvement in the method for preparing diffusion resistant clad thermocouple cable by placing the thermocouple wires in MgO powder or pellets on a strip of metal cladding material and longitudinally bending the strip of cladding material around the thermocouple wire and the MgO and welding the resulting seam closed is achieved when the resulting composite cable is placed on a second metal cladding strip such that when the second strip is bent longitudinally around the composite cable the resulting seam is displaced from the welded seam of the first cladding strip.
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.
