Patent GB-2091420-A (GB)
Title: Combined shear/compressional wave seismic exploration
IPC: G01V1/153
Filed: 1981-01-20
Abstract: In a method of seismic exploration using swept-frequency signals, compressional and shear waves are emitted simultaneously. Typically the waves are generated by swinging-weight vibrators acting through a single baseplate. If the frequency of the shear vibration is one-half that of compressional vibration, the downward vertical forces can be phased as shown relative to the horizontal forces to minimize the horizontal slippage of the baseplate. The sensitive axis of the geophones is inclined to the vertical. For defined ranges of sweep rate, separate compressional and shear records are obtained by cross- correlating the geophone signal separately against the vertical and horizontal emissions. <IMAGE>

Title: Magnetic tape recording
Inventor: THOMAS MICHAEL EDWARD
IPC: G11B27/029
Filed: 1981-12-07
Abstract: A transverse-scan or helical-scan magnetic tape recorder may have its playback head adjustable axially of the drum, so as to ensure that it can be fully aligned with the track it is supposed to be reading, and also for other reasons. In this invention the playback head 22 can be moved to a position 22c ahead of both the record head 20 and the erase head 18 such that while the record head is recording, the playback head plays back signals recorded on the tape prior to their being erased by the erase head. The played back signals can be subjected to a processing operation, e.g. mixing or special effects, and the processed signals then applied to the record head for re-recording on the same tape. In this way mixing and special effects can be achieved with simple operating procedures and with one less recording than hitherto required. <IMAGE>
Patent GB-2089572-A (GB)
Title: A Puffer-type Gas-blast Circuit Interrupter
IPC: H01H33/915
Filed: 1981-12-08
Abstract: A puffer-type circuit-interrupter has an annular piston 142 slidable on a fixed contact 96 within a cylinder 146. A spring 154 biases piston 142 towards a fixed electrode 84 which has a movable contact 108, connected to an operating member 112, in sliding engagement therewith. A first abutment 152, on tube 150 secured to piston 142, engages a second abutment 136 on contact 108. Closure of the interrupter causes compression of spring 154 by piston 142. Upon opening of the interrupter, the abutments 152, 136 part and movement of the piston 142 by spring 154 is only minimal. The amount of piston movement at this stage is determined by the inertia of piston 142, spring 154 and tube 150, the force of spring 154 and the "impedance" of the gas circuit of the interrupter 12. Consequently, piston 142 is still moving when the contacts have attained their fully-open position and, therefore, a gas flow is at a maximum when it is most likely to contribute to extinguishment of the arc. <IMAGE>
