Abstract: An identifying shield for an electronic instrument housing is formed of elastically stretchable and deformable material. The shield elastically surrounds the periphery of the instrument housing adjacent to its front panel surface, and defines a central opening that exposes the front panel for viewing by an operator. A first portion of the shield defines the central opening overlying the front panel of the instrument housing, and a second portion extends rearwardly from the first portion defining a peripheral band that engages the periphery of the case along its sidewalls adjacent to the front panel. An inwardly extending flange projects from the rearward edges of the peripheral band to enhance frictional engagement with the underlying sidewall surfaces of the instrument housing.

Abstract: A meter measures a voltage across a quasi-diode, the voltage caused by a current flowing through a resistance which changes substantially exponentially with changes in a medium being sensed. The meter comprises a logarithmic current measuring circuit coupled to the resistance to provide a measurement output that is a logarithmic function of the current flowing through the sensing resistance. A switchable current source is controlled by a switching circuit to repetitively output first and second current values. A reference logarithmic circuit is connected to the switchable current source and is physically coupled to the logarithmic measuring circuit so as to be maintained at a substantially equal temperature value. The logarithmic reference circuit manifests a first voltage in response to the first current value and a second voltage in response to the second current value, both voltage values dependent upon the temperature of the logarithmic reference circuit.

Abstract: A position housing assembly, for a generally cylindrical infra-red thermocouple sensor of the type having a sensing face at one end and one or more electrical conductors extending from the other end, includes a cylindrical housing having a central bore for telescopically receiving a sensor. A conical reflective surface, at one end of the housing, concentrates infra-red rays toward the face of the sensor; the reflective surface may be integral with the housing or it may be carried by a separable adapter. A separable handle attaches to the housing, and extends into the housing wall for guiding conductors from a sensor to the exterior of the housing. A set screw on the housing clamps the sensor within the central bore. Adjustable positioning legs extend axially from the housing to position it relative to a test surface. In one embodiment the legs are attached to a moveable positioning bracket, while in another, the legs slide within axial bores integrally formed in 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: A separable electrical connector with a housing formed of electrically insulating material includes an external grounding terminal anchor positioned in a grounding strip groove on the surface of the housing. The groove, in the form of an open-sided recess, receives and positions a suitably dimensioned grounding strip of electrically conductive material. The strip is coupled to the anchor by a screw fastener which engages mating screw threads formed in the anchor. One or more display surfaces surrounded by upstanding protective wall surfaces are formed on the exterior surface of the housing for the display of identifying indicia, and the base surf ace of the external grounding strip groove may be used as a display surface, if desired, in the absence of a grounding strip. The grounding terminal anchor may be made of electrically conductive material so that an anchored conductive grounding strip will be coupled to the housing both electrically and mechanically.

Abstract: A support assembly for displaying a banner on a flagstaff includes a base support for holding the base edge of a banner in extended condition, and an adjustable length deflector element extending from a point between the ends of the support element. The free end of the deflector element is attachable to the fabric of the flag at a central point within the flag's outer peripheral borders. The defector element is formed of resilient material and it is coupled to the support element by a guide bracket that includes a guide channel for bending the deflector element through a right angle. Dimensions of the guide channel and the deflector element are selected so that the deflector is free to slide telescopically within the channel to vary the length of the portion of the deflector extending from the support element. At the opposite end of the deflector, a right-angle projection engages a hole formed in the support element to retain the deflector in a desired extended position.

Abstract: A processor is described for monitoring a sensor whose output signal follows a nonlinear curve in response to a linear change in a monitored phenomenon. The processor converts the sensor signal to a linear output proportional or equal to the phenomenon being monitored. The processor includes a memory for storing a table which includes a starting data point value S on the curve, a starting slope value S' to another data point on the curve, a starting curvature value S" for a succession of the data points on the curve and a plurality of rate of change of curvature values S'" for the curve. The values of S'" for a first region of the curve are calculated based on an initial output signal interval between data point values. The values of S'" for each succeeding region of the curve are based on increasing, by a preselected factor, the signal interval between data point values. The processor includes a calculation device for computing repeated aditons of the S', S", S'" values.

Abstract: Three-point safety belt restraint systems of the type commonly installed in passenger motor vehicles for use by the occupants can be adapted to accommodate users (i.e. wearers) including children, who may be of shorter than average stature through the incorporation of an add-on device for repositioning the shoulder restraint belt in such systems to make the restraint system adjustable to the comfort and safety of the user.

Abstract: A sheet of flat paper or poster stock has information printed on one side in the form of separate and independent areas of discrete information units, and a large-scale poster-like pattern occupying substantially the entire available area of the opposite side surface of the sheet. A plurality of straight crease lines are marked on one surface of the sheet, arranged to define a coordinate grid-like pattern surrounding the various discrete information units, such that the sheet may be folded conveniently along the crease lines to form a fold-out booklet having a plurality of leaves with units of information printed on each leaf, similar in nature to the pages of a book.

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: 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.
