Abstract: The present invention is directed to a human body protecting element for use with and attachment to an article of clothing, such as sports apparel, to protect a wearer from impact and frictional forces, such as road rash. One exemplary body protecting element includes a first part having a first locking member. The first part is for placement along an inner surface of the article of clothing. The body protecting element also includes a second part having a second locking member that is complementary to the first locking member and results in a mechanical coupling (e.g., a snap-fit attachment) between the first and second parts when the first and second locking members engage one another. The second part is for placement along an outer surface of the article of clothing and includes an outer ground contacting contoured surface.

Abstract: A shaft assembly is provided to reduce breathing mode vibrations and resulting noises. The shaft assembly includes a shaft member having an outer surface and a damping member constructed at least in part from a damping material and including a substantially annular body and generally opposing ends. The opposing ends are biased such that at least a portion of the damping member engages with the shaft member.

Abstract: A paint brush merchandising system characterized by a display hanger including a wire body bent intermediate its length at an acute angle to form a rear article storage portion and an angled front article display portion. Attachment means are provided at the rear end of the wire body for removable yet secure mounting to an upright panel such as an aperture panel with the storage portion extending substantially normal to the panel and the display portion at an upwardly inclined angle in the vertical plane of the storage portion. The display hanger also includes a covering of soft resilient material on the display portion over substantially the length thereof which covering is operative to effect a wedging or binding action at the handle hole of one or more paint brushes threaded thereon for holding such brushes upwardly tilted on the display portion for easy removal and viewing.

Abstract: A pluggable module actuation and retention device comprising a spring housing fastened to a printed circuit board and having openings which contain a matrix of contact springs extending from said board. A bail retaining latch is fastened to the spring housing and an actuator bail is pivotally mounted on the spring housing and has an opening which overlies the openings in the spring housing. A module to be actuated and retained has a matrix of pins corresponding to the matrix of contact springs and is provided with actuator tabs. Actuator tab mating means are provided on the spring housing for engaging the module actuator tabs when a module is inserted through the opening in the actuator bail to align the matrix of pins with the matrix of contact springs. Camming means on the actuator bail are effective when the bail is pivoted in one direction to engage the actuator tabs and slide the module to move the matrix of pins on the module into engagement with the matrix of contact springs.

Abstract: Vertically disposed side walls on a vehicle body are completely removable or are pivotable outwardly through an arc of at least 90.degree. and not more than about 180.degree. to facilitate loading and unloading of the vehicle body.

Abstract: A printed circuit board is provided with via holes and these holes are provided with a base coat of conductive metal, a coating of insulating material deposited on said base coat, and a second coat of conducting metal deposited on said insulating material. The metal coatings are interconnected to one or more surfaces of the board and the base coat is connected to at least one internal power, ground or signal plane. This via hole construction facilitates the making of engineering changes by simply deleting the interconnection between the metal coatings at the board surface and subsequently connecting the desired point to an alternate point on the circuit board.

Abstract: An improved magnetic tape test article includes a plurality of longitudinally spaced-apart test sections. Some of the test sections are repeated to facilitate recorder tests under different tape wrap conditions. One of the tests is a compound test enabling several simultaneous measurements of several parameters of the recorder. The tests are particularly adaptable for helical scan digital signal recorders. The tests measure parameters such as head to medium spacing, tracking (skew, servo offset and the like), readback circuit performance, including clocking, phase tolerances, error detection and correction operations, response to dropouts, resynchronization response and amplitude tolerances. Profile of the spacing between the record medium and the head is measured over the length of the recorded path around the cylindrical mandrel.
