Abstract: An electrical connector comprising a housing and electrical contacts connected to the housing. The electrical contacts comprise paired signal and ground contacts, and additional ground contacts. The additional ground contacts are arranged relative to the paired contacts to divide the paired contacts into subdivisions of equal numbers of the paired contacts. The subdivisions and the additional ground contacts are arranged to allow for multiple relative orientation connections of a mating connector.

Abstract: The present invention provides a method of depositing a passivation layer on the surface of a superconducting ceramic oxide wherein the passivation layer is a layer of an oxide of Al, Bi, Si or Al-W.

Abstract: A CaF.sub.2 passivation layer is applied on the surface of a superconducting oxide by evaporation which does not disrupt the superconductive properties of the superconducting oxide.

Abstract: An improved rotatable flagpole arrangement for supporting a flag or banner includes an elongate pole with structure thereon for mounting a flag or banner, a lower stop surface attached to the pole and a novel bearing arrangement between the stop surface and a support surface which utilizes a pair of embossed washers. The pole may be formed of a flexible material such as PVC so that it curves away from the wind as it rotates relative to the support socket, which creates a novel, dynamic visual effect.

Abstract: A cassette for a scratch strain recorder has a rotatable supply bobbin geared directly to a rotatable take-up bobbin so that rotation of the take-up bobbin will be equal in amount but opposite in direction to that of the supply bobbin. The recording tape is formed of a roll of flat resilient material which has one end attached to the supply bobbin and which, in the unused condition, is almost totally wound around the supply bobbin except for the other end which is attached to the take-up bobbin. The tape is driven by a capstan and pinch roller, the capstan being arranged for driving connection to a drive shaft of the strain recorder itself. Because of its inherent resilience the coil tries to straighten, i.e. unwind, and this assists rotation of the two bobbins when the capstan is operated and the direct gear interconnection causes an equalization of the spring forces between the two bobbins as the cassette progresses from an unused condition to a nearly completely used condition.

Abstract: An elongated gauge bar bent along its longitudinal center to form a pair of longitudinally extending flanges at right angles to each other and each having inner and outer surfaces and an outer longitudinal edge. Each outer surface is provided with transverse dimension indicating lines calibrated in an arithmetical system differing from that of the lines of the other surface. The gauge bar is used on the guide bar of a radial saw to accurately indicate a dimension at which a workpiece is to be cut by the saw blade.

Abstract: An impact line printer having a plurality of high velocity, small mass pivoted print hammers. Both a high print density and an unusually high impact printing force is achieved by actuating the hammers by a corresponding plurality of closely packed solenoids whose diameters are substantially larger than the spacing of the print hammers. These solenoids are mounted in the same vertical space but engage their associated print hammers a predetermined distances S.sub.1 and S.sub.2 from the hammer pivot axis. Appropriate selection of these distances S.sub.1 and S.sub.2 achieves uniform printing pressures from all of the hammers while using identical solenoids and identical drive currents. A paper engaging clamp includes a driven drive roller mounting a pair of resilient O-rings. A pair of pinch rollers, rotatably mounted on pivoted plastic lever arms, are adapted to clamp the paper or other printing medium between the rollers and the O-rings upon application of a force to the lever arms.
