Abstract: 1524706 Multichannel gramophone pickups MICRO-ACOUSTICS CORP 17 Sept 1975 [18 Sept 1974] 38182/75 Heading H4J A stereophonic pickup has two transducers 11 L, 11 R (Figs. 1, 6) held between elastomeric blocks 12 secured to the pickup case. In use forces are transmitted to contact points 13 on the transducers 11L, 11R by spaced projections 21 on a resolver 15 on which a stylus arm 16 is supported. The resolver 15 is secured under tension to the case by a flexible pivot anchor 17. The resolver 15 contacts a pair of stabilizers 18 of elastic material to provide mechanical balance, the contact regions of the stabilizers 18 and the projections 21 on the resolver 15 are at the four corners of a square, all contact regions being equidistant from the pivot point of the pivot anchor 17. The transducers 11L, 11 R may be of piezoelectric or electret type and preferably have a free-free resonance in excess of 40 kHz. The pickup may have a frequency range of 0 to 50 kHz for playing discrete four channel recordings. The pivot anchor 17 is coaxial with the stylus arm 16. At rest (Fig. 6) the transducers 11L, 11R are slightly but equally stressed. Lateral motion causes stressing of one transducer while vertical motion causes equal stressing of both channels. Complex motion causes stressing of both transducers. The stylus resolver 17 is of rigid moulded plastics material. The elastomeric blocks 12 are of moulded butyl rubber. The blocks 12 and stabilizers 18 may be attached by providing inserts in the cartridge case or by cementing of the elastomeric materials. The stylus arm 16, stabilizers and pivot anchor 17 may be on a replaceable holder 31, there being matching slots and projections on the main body 33 and the replaceable holder 31 respectively (Fig. 8). A spring clip 47 on the replaceable holder 31 engages a catch 43 on the body 33. Set screws 49 adjust the stress and position of the piezoelectric members 11 and these have caps 48 which contact the projections 21. The stabilizers 18 are inserted into recesses 55 and fit into matching holes in the resolver 15.

[Also in Group XIX] An address selection circuit for data storage apparatus comprises a matrix of transformers F, Fig. 2, e.g. ferrite cores or formed from holes in a ferrite plate, each transformer having row and column primary half-windings W1-W4 and M1-M4, and an address is selected in the store by first priming a transistor switch in the appropriate row and column circuits and then applying a drive pulse to all the row and column windings from transformer TR1, whereupon the magnetization of the selected transformer F is reversed and a pulse is obtained in its secondary winding S. The store may be a magnetic drum or a ferrite core matrix, in which latter case a selection circuit is provided for the row windings and for the column windings of the store. The transistor switch associated with each row and column conductor of the selection circuit is shown in Fig. 3. A priming pulse is applied over transformer TR2, whereupon T9 conducts and builds up a charge on the base of T1 which is retained until the common drive pulse is applied to cause the half-current to flow through T1, the non-primed transistors T2-T3 remaining non-conductive. In order to provide for reading and re-writing, the transformers F are biased to revert to their initial state after operation.

Abstract: 1483649 High pressure apparatus SIGURDSSONS MEK VERKSTAD 6 Sept 1974 [14 Sept 1973] 39115/74 Heading B1X A method of increasing the pressure exerted on a material in a high-pressure chamber to a desired level and maintaining the pressure for the desired time, and, if desired, controlling the pressure at that level, is effected by means of a first pressure-exerting force acting on the material throughout the duration of the pressure treatment, the method also including the steps of compressing a preselected volume of a pressure compensating medium which is in the liquid state up to the maximum working pressure to a selected, adjustable pressure lower than the first-mentioned pressure by means of second pressureexerting force in such a way as to cause the pressure of the medium to react, during the pressurising phase, on the force generating the first-mentioned pressure, and causing the pressure of the medium, should it deviate from the selected value, to be restored by regulating the volume and/or the pressure of the medium. Where the volume of the material under pressure is reduced as a result of reaction or phase conversion, the applied pressure may be maintained at a constant value by a controlled reduction of the volume of the medium. In one embodiment, a high pressure apparatus comprises a pressure cylinder 1, a central reaction chamber 2 for material 5, and two pressure pistons 3 attached to presses 4. The cylinder is surrounded by three concentric steel jackets, 6, 7, 8. Gaps 10 and chamber 11 are filled with a hydraulic liquid, preferably oil, which forms a support pressure medium and a pressure compensating medium for the pressure cylinder and the pistons. The spaces 10 and 11 are connected via a channel 14 to a valve 15, set to open at a selected pressure. The method and apparatus is for the emission of graphite to synthetic diamonds and for making boron nitride crystals under controlled pressure/temperature conditions.
