Title: Improvements in or relating to piezo-electric crystals
IPC: H03H9/19
Filed: 1935-05-31
Abstract: 457,342. Piezo - electric crystals. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Bokovoy, S. A.; 705B, Woodlynne Avenue, West Collingswood, and Baldwin, C. F.; 100, Manheim Avenue, Oaklyn, both in New Jersey, U.S.A.) May 31, 1935, No. 15929. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 3, 1936.] [Class 40 (v)] Relates to methods of cutting piezoelectric oscillators from a mother crystal, so as to operate with zero temperature coefficient or with a desired positive or negative coefficient. The method covers the cutting of crystals intended to vibrate at a frequency which is a function of their thickness dimension, or of their contour, i.e. their length or breadth. As shown in Figs. 1, 2 and 3 the crystal element 4 or 5 is cut from a block 3 forming part of the section 2 cut at right-angles to the optical axis Z. The top and bottom surfaces of the element 4 or 5 are parallel to an X axis, but are inclined at specified angles both to the Z axis and to the plane of a major face M or a minor face N of the mother crystal. A formula is given which relates the thickness of the crystal element to the required frequency, the length or breadth in this case being immaterial. The element can be selected to give a definite positive or negative temperature coefficient by varying the angle of cut. Alternatively, as shown in Fig. 12, cutting of the crystal element 4 or 5 is orientated with respect to W-axes (which cut the X axes at certain specified angles) and is tilted about a Y axis to secure the desired temperature coefficient. Fig. 9 shows how the characteristics of a " cut varies as it is rotated through 360‹ about the optical or Z axis. The method is also applied to the cutting of " contour " crystals which vibrate either along their length or breadth, irrespective of their thickness.

Abstract: 1,032,003. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 12, 1965 [April 17, 1964], No. 16037/64. Heading H1K. In a four-layer diode or an SCR the semiconductor material is treated to reduce the carrier lifetime and one of the outer layers is provided with a higher conductivity surface layer of the same conductivity type to compensate for any increase in the forward voltage drop due to the reduction in carrier lifetime. As shown, an SCR is produced by sealing an N-type silicon wafer inside a quartz tube filled with argon and containing gallium and heating to produce P + -type surface layers. The wafer is then coated with a layer containing gold by dipping it in a solution of nitric acid containing chlorauric acid and allowing to dry. A solution containing boron trioxide is painted on the surface of layer P 1 + and also allowed to dry and the wafer is then heated to diffuse the gold throughout the wafer to reduce the carrier lifetime and to diffuse the boron into layer P 1 + to form layer P o <SP>++</SP> which reduces the forward voltage drop of the device. A gold-antimony pellet is alloyed to layer P2+ to form region N 2 + and a molybdenum electrode 2 is applied while the pellet is molten. Molybdenum electrodes 1 and 3 are soldered to layers P o <SP>++</SP> and P 2 + using an aluminium solder.

Abstract: 1,150,152. Route setting system. WERK FœR SIGNAL-UND SICHERUNGSTECHNIK BERLIN VEB. 12 April, 1966, No. 16060/66. Heading B7N. In a route setting circuit arrangement, a number of prefabricated electronic units are provided each of which is associated with a route element and includes a similar control circuit. The units are connected in a manner which simulates the layout of the track being controlled. Assume a route between main signal A and auxiliary signal N; on actuation of buttons T(AS)-and T(AZ) all the setting elements 1 of the units involved in the route are energized, i.e. main signal unit A, shunting signal units R 1 , R 2 , points control units W 1  and W 11 , crossover unit Kr, signal unit N, track section unit Gl and overlap section unit D; and apply an output pulse to an associate AND gate 2. By input connections (not shown) the gates determine the admissibility of the setting, the line clear condition, the signal stop position and/or the track section block interlocking conditions and if these conditions allow pass the pulse to a storage unit 3. The stored pulse is passed to AND gate 4 and establishes signal path I, through the units which indicates that the route is free, additionally the setting up of this path effects the throwing over of any incorrectly positioned points. On completion of the path to main signal unit A a second path II is set up via AND gates 5 of the units which interlocks the units forming the route so that the points are locked and any other setting which conflicts with the route is excluded. The output from AND gates 5 is stored in storage elements 6 and sets up a third path III, via the AND gates 7 of the respective units which again checks that all preliminary requirements have been met. The output of AND gates 7 is stored in storage unit 8 and a fourth checking circuit IV, running through AND gates 9 energizes the reed relays 10. Pulse generator 11 in overlap unit D now energizes path V, via the picked up reed relay contacts and supplies a code pulse signal to main signal unit A. This signal which is coded in terms of the permissible speed may be modified in translators 13 associated with each set of points. The coded signal when received in the signal unit energizes this unit to provide the correct entry signal.

The flap (not shown) is attached to a tail member c and vertical movement of the handle acts through an arm d to oscillate the member c. The handle a and member c are also pivoted to a member b which is fixed relative to the unit. Rods f 1  and f 2  with angled ends can be turned to push the arm d in either direction over its bottom dead centre position so that the flap can be used to propel the boat forwards or backwards. The rods are biased towards their inoperative positions by springs g. As illustrated, the unit has a casing e to which the rudder j and pintles n are attached; however, the casing and the rods f 1  and f 2  may be omitted, in which case the arm d is moved by hand into its required mode of operation and the rudder and pintles are attached to the member b. The flap may be flexible, may have the general shape of a dolphin's tail and may incorporate spring reinforcement. If a non-flexible flap is employed, it is so attached to the tail member that it is free to pivot through a limited arc relative to the tail member.
