Abstract: A promotional display structure has a plurality of elongate strips of stiff but bendable material assembled in a pack with their obverse and reverse faces alternating in the pack, the first face having textual display including promotional matter and in some cases also cartoon matter, the second face having illustrative cartoon matter and in some cases also promotional matter, the pages of the pack being releasably connected at one end of their elongation, for example by gumming or other form of binding, and being readily detachable by hand from the remainder of the pack. One or more lines of weakness may be formed in the strips, for example by perforation or crimping, to facilitate folding of a part of the strip against the remainder of the strip, and a releasable fastening may be provided to retain that part in the folded condition. There are also provided a method of forming the promotional display structure, and a method of disassembly thereof.

Abstract: A booklet for disseminating advertising and technical information has a number of pages secured in a bundle between front and back covers, the pages being secured to a binding formed between the front and back covers, the pages being individually releasable as a whole from the binding, or being weakened across their height dimension adjacent to the binding, so as to permit a major portion of the page to be separated leaving a stub secured to the binding, the pages being elongated and having on their front and back surfaces cartoon-displaying areas and material of an advertising technical nature, the cartoon-displaying areas being individually separable from the remainder of the page. The front cover, at least, may also include cartoon-displaying and advertising technical material. The bundle of pages may have cartoon-displaying material and advertising technical material arranged as to be presented alternately through the bundle.

In a form of the invention for use with single wires or a pair of multiple wires, each wire is provided with an individual antenna-effect inhibiting means, such as a ferrite housing, adjacent to a connector thereon.

Abstract: Method and apparatus are provided for visibly outlining the energy zone to be measured by a radiometer. The method comprises the steps of providing a laser sighting device on the radiometer adapted to emit at least one laser beam against a surface whose temperature is to be measured and positioning said laser beam about the energy zone to visibly outline said energy zone. The apparatus comprises a laser sighting device adapted to emit at least one laser beam against the surface and means to position said laser beam about the energy zone to visibly outline said energy zone. The laser beam may be rotated about the periphery of the energy zone. In another embodiment, a pair of laser beams are projected on opposite sides of the energy zone. The laser beam may be further pulsed on and off in a synchronized manner so as to cause a series of intermittent lines to outline the energy zone. Such an embodiment improves the efficiency of the laser and results in a brighter laser beam being projected.

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 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.
