Abstract: In an electric field probe for use in calibration of electromagnetic susceptibility testing equipment, processing circuitry for converting electric fields to digitally modulated light transmitted by a fiber optic cable, and circuitry for converting light supplied through a fiber optic cable to current for operating the processing circuitry, are on printed circuit boards that have border portions with conductive edge plating clamped between opposed edges of shells that form a circuit board enclosure. Antenna elements comprising conductive traces on the circuit boards protrude outward from the enclosure through gaps in the plating.

Abstract: A support bracket for mounting an engine component to a surface, such as to a cylinder head or engine block. In an embodiment, the support bracket includes a base member, a shelf member and a spacer. The base member has a back portion with a shape that defines a forwardly facing channel. The spacer is shaped to be matably received in the channel, optimizing load distribution between the spacer and the base member. A bolt hole extends through the spacer and is aligned with a bolt hole in the base member. The shelf member is welded to the base member to permanently capture the spacer in the channel. Welding the spacer is unnecessary. The spacer may be made of powdered metal. The spacer provides a free length portion of the capscrew that mounts the bracket against a surface, the free length accommodating longitudinal stress on the capscrew.

Abstract: A toy vehicle has an object projecting apparatus mounted on a chassis and enclosed by a removable body or cover. The object projecting apparatus includes a spring loaded arm and a catch and release mechanism. The spring loaded arm can be shaped like a baseball bat or have a hand or shoe for hitting, throwing or kicking a ball. The catch and release mechanism preferably has several spaced apart movable tabs which selectively engage a catch tab o the arm. This allows the spring loaded arm to be releasably held at one of several positions so that when released the arm will strike or throw a ball at different forces, each force corresponding to the selected position.

Abstract: A shipping and return mailing label includes three parts: (1) a shipping label, (2) a return label, and (3) an intermediate card connected to the two labels by lines of perforations, with the front face of all the parts of the label assembly being exposed as the label assembly is mounted on a backing sheet, so that, for example, bar codes may be directly printed on each of the three parts. The return label is coated with adhesive on its rear side, the card may be free of adhesive, and the shipping label may be of greater extent than the return label and the card, and may have stripes of adhesive located on its three free edges, so that the entire assembly, following printing, may be folded in a Z-shaped manner, and secured to a carton to be shipped.
