Patent CA-2057569-A1 (CA)
Title: Framing system for signs
Inventor: VERRET NORMAND
IPC: G09F13/04
Filed: 1991-12-12
Abstract: The new  framing  system for signs provides a method of stretching the flexible sign material across the opening of a frame.   The  tensional devices are installed manually from the outside of the sign at regular spacings on the edges of the flexible sign material.  The tensional devices are installed by closing the device on, and by the same movement, puncturing retaining holes on the edges of the flexible sign material.  The adjustment of the tension of the flexible sign material is done by pushing inwardly on each tensional device to engage it onto a series of serrations inside a slot facing outwardly along the edges of the frame.  The outside edges of the frame are held rigid with frame members extending from the bottom of the sign, and thus eliminating  the  need for support members, between the flexible sign material and the lamps, which normally transmit shadows to the face of the sign.  The new framing system can be re-opened for maintenance purposes using a slot type blade screw-driver to pry the tensional  devices out of the serrations.  The tensional devices and the slot on the periphery of the sign are covered by a cap which locks in place on mating lips, and which can be removed manually by twisting it inwardly along its length.

IPC: H04N5/783
Filed: 1990-11-29
Abstract: An apparatus and a method for reducing cross talk in tape recording and playback systems is disclosed. A single magnetic track containing D data bytes of the prior art is divided into W  subtracks, each containing D/W data bytes. The tape recorder is capable of recording at a preselected full speed and integral fractions thereof. When recording is done at less than full speed, the W  subtracks which comprise a track are offset longitudinally, such that the area covered by the W subtracks approximates the area of a single track of the prior art recorded at full speed. To further suppress cross talk, wide write heads and narrow read heads, or opposite azimuth angle heads may be used.

Title: Ball race slewing gear
Inventor: FREITAG HELMUT
IPC: F16C33/76
Filed: 1992-11-27
Abstract: ABSTRACT       BALL RACE SLEWING GEAR            Ball race slewing gear, for example, for open-cast mining equipment, are oil-lubricated ball race lower parts made up of segments and receiving the supporting balls supporting the superstructure, which can be rotated in relation to the lower frame.  To improve the sealing of the segments (1) against oil leaking out of the separating lines and to make it superfluous to disassemble the ball race slewing gear for each renewal of the seal, the end faces of the segments (1) are formed with recesses (2) which enclose the ball race (3) in U-shape and whose arms (5) are open in the direction of the inside and outside of the ball race lower part and which receive strand-shaped rubber or plastics sealing sections (6).  The sealing sections (6) have segment side sealing lips (9) and a continuous cavity (10) and are each disposed completely in one of the two abutting segments.          The sealing ring enclosing the ball race lower part and the internal oil collecting ring are interrupted in the zone of the separating lines and closed by readily removable extension members (7, 8).  A leakage monitoring device is connected outside the sealing sections (6) in the zone of the transition between the web (4) and arms (5) of the recess (2).     Fig. 4
