Patent CA-2011328-A1 (CA)
Inventor: BERNIER MARC
IPC: H01Q1/12
Filed: 1990-03-02
Abstract: A  mechanical  bracket  for  mounting  a telecommunication  antenna  on  a  metallic  tower comprises a pipe section to secure the bracket to the tower.  The angular position of the pipe section about its longitudinal axis is selected to appropriately orient the bracket.   A transversal pivot bridges a pair of spaced apart parallel plates of the bracket. The antenna comprises a pole member with a free end pivotally mounted on the pivot between the two plates. A bolt and nut assembly traverses the pole member and two arcuate slots respectively made in the parallel plates.   In operation,  the pole member is rotated about the pivot with the bolt sliding in the two arcuate  slots,  and the bolt and nut assembly  is tightened when a desired position for the pole member, and therefore for the antenna, is reached to thereby lock the pole member and the antenna in this position.

Patent CA-2013253-A1 (CA)
Inventor: MACHURA BERNARD C
IPC: H01R24/50
Filed: 1990-03-28
Abstract: ABSTRACT OF THE DISCLOSURE A receptacle connector and a plug connector for connecting a coaxial cable of 75 ohms or greater to a printed circuit board without affecting the outside configuration of their shells. At one end, the receptacle connector forms a spring contact receiver portion for resiliently retaining the plug end of the plug connector. The plug connector terminates a coaxial cable at its other end. The receiver portion of the receptacle connector is right-angled to a three-legged terminal section for solder connection at the printed circuit board. The receptacle and plug connectors comprise an outer shell member, a dielectric member, and a center conductor. The shell members are stamped and formed to maintain an exact constant inside diameter to the shells. The center conductors are stamped and formed to maintain an exact but variable outside diameter which is used to change the terminating impedance of the respective connector. The center conductors are subsequently insert molded into the dielectric members during their formation. The molded dielectric members are preferably of an insulative and low dielectric constant material, such as Teflon. The connectors are assembled by forming the outer shells around the dielectric members which have locating means for determining a positive relationship between the shells and dielectric members.

Abstract: A plummer block for the arm of a Florentine blind with articulated arms, comprising a supporting block (2) which can be clamped to a supporting part, and a bearing block (4) which can tilt about a substantially horizontal axis into the descended position and on which an articulated arm (20) is mounted so as to be able to pivot about an axis aligned transversely to the tilt axis, the bearing block (4) and the supporting block (2) being coupled by a coupling rod (5) which permits and limits the tilting movement and has a thread (8) and adjusting nut (9), and a blocking slide (15) being coupled to the articulated arm (20), which blocking slide is displaceable transversely to the axis of the coupling rod (5) and blocks the same in the descended position. The technical problem is to construct the plummer block such that the functioning of the stop is independent of the blocking slide and that a blocking slide capable of being manufactured in a simple manner can be used. The adjusting nut (9) is constructed as a solid cylinder with thread passage in the radial direction. A cylindrical segment pan (35) is provided as a receptacle for the cylindrical face (32) of the adjusting nut (9). The blocking slide (15) touches the cylindrical face (37) of the adjusting nut (9) in the tilted position.

Abstract: Disclosed is a method of forming a vanadium-rich, multi-component reversible, electrochemical hydrogen storage alloy directly from a vanadium-reductant alloy without first obtaining pure vanadium. In one exemplification the vanadium-reductant alloy is a vanadium-aluminum alloy of low oxygen content, while in another exemplification the vanadium-reductant alloy is refined by electron beam evaporation, and in a third exemplification the vanadium-reductant alloy contains further reductants that reduce the oxygen content without adding impurities to the alloy. The vanadium-reductant alloy is directly used as a precursor in forming the electrochemical hydrogen storage alloy.
