Title: Improvements in or relating to piezo-electric crystals
Inventor: BECHMANN RUDOLPH
IPC: H03H9/02
Filed: 1949-06-22
Abstract: 679,023. Piezo-electric crystals. POSTMASTER GENERAL. June 9, 1950 [June 22, 1949], No. 16628/49. Drawings to Specification. Class 40 (viii). A piezo-electric crystal element consists of a square prism of anhydrous ethylene diamine tartrate whose square face lies in the plane of the X and Y axes, and an edge of the square forms an angle within either the range 79-88 degrees, or 10-30 degrees with the Z axis. The Y axis is the diad axis of symmetry, the X axis makes an angle of 15¢ degrees with a line normal to the Y axis and lying in the major surface of the crystal, and the Z axis completes the rectangular system of axes. When an electric field is applied in the direction of the Y axis, the crystal can vibrate in four coupled modes resulting from the interaction of the longitudinal and contour shear modes. One of these modes is found to be suitable for the desired operation of the crystal. Specifications 655,994 and 677,898 are referred to in the Provisional Specification.

Title: Improvements in or relating to apparatus for starting alternating current slip-ring motors
IPC: H02P1/34
Filed: 1956-05-30
Abstract: 820,638. Control of A.C. motors. OFFICINE MECCANICHE RIUNITE S.p.A. May 30, 1956 [Oct. 17, 1955], No. 16777/56. Class 38 (3). Relays 21 ... 24 for controlling the rotor resistance of an induction motor M3 are subjected to the difference between voltages representative of the stator and rotor voltages. respectively, the said representative voltages being derived through transformers TS, TR, and applied to rectifiers RS, RR. When power is supplied to the motor while the rotor is still stationary, the voltage between rectifier-terminals 6, 7 is zero. As the motor-speed increases, the difference-voltage becomes sufficient to operate relay 21 and close contacts 21a in series with contactor coil 31, whereby contacts 31b short-circuit resistance-section R1 and contacts 31a close in series with the relaycoil 22. On further increase of speed, the relay 22 operates to remove the resistance-section R2 and to prepare for the removal of section R3. Thus, the rotor resistance is appropriately reduced as the speed of the motor rises. The rectifier RR is shunted by a resistor R so as to complete the circuit for the relay coils. During reverse-current braking the rectifier RS blocks the circuit of the relays. Specification 794,892 is referred to.

Title: Improved method of and apparatus for heating and deaerating or degasifying water
IPC: B01D19/00
Filed: 1931-06-12
Abstract: 372,589. Heating feedwater; scrubbers. RECUPERATION THERMIQUE ET EPURATION, 98, Rue de Charonne, Paris.-(Assignees of Gibson, G. H. ; 70, Oakwood Avenue, Upper Montclair, New Jersey, and Rohlin, V. A.; 17th Street, Philadelphia, both in U.S.A.) June 12, 1931, No. 17187. Convention date, June 13, 1930. [Class 64 (i).] In heating and deaerating water by treatment with steam first in a heating stage and then in a deaerating stage after which a part of the steam is vented in admixture with the liberated air, the capacity of the apparatus is increased by restricting the quantity of steam brought into contact with the water in the deaerating stage to an amount not greatly exceeding the amount vented. In one form of apparatus, water entering at C<3> passes through a trap E<1> and spreading device E on to a stack of trays F, from which it passes through a water seal H<1> on to a second stack of trays G ; after traversing these, the water drops directly into the chamber X. The steam entering at A<2> is deflected by baffles K and fills the space surrounding the trays F and the intertray spaces thereby heating the water ; the residue of uncondensed steam passes through apertures J<3> into a conduit J and thence through the spaces of the trays G to an outlet A<4> leading to a condenser C and air pump. The supply of water from the pipe B is regulated by a float b operating a valve B<1> through which the water passes to the vent condenser C and then to the inlet C<3>. The trays F are of sector shape provided with radial slots f<1>, Fig. 2, for the passage of water, and with notches f<2> in the outer rim for the passage of steam. The slots in successive vertical layers are staggered. The trays G, Fig. 4, have a central stiffening rib g<2>, ports g<3>, g<4>, and tongues g<6> engaging with recesses g<5> to facilitate assembly. The ports in successive layers are staggered. In an alternative form, the steam flows in parallel with the water through both sets of trays.

Title: Depth-measuring echo sounder
Inventor: COOKE COLIN HENRY
IPC: G01S15/18
Filed: 1965-04-23
Abstract: 1,147,191. Echo sounding. SMITHS INDUSTRIES Ltd. 30 March. 1966 [23 April, 1965] No. 17352/65. Heading H4D. In a marine echo-sounder providing a graphic record of received echoes and a separate digital indication of seabed depth, any deviation between the recorded sea-bed depth and the digitally indicated depth is detectable from the record. In the embodiment of Fig. 1, echo signals are fed through receiver amplifier 13 to electrochemical recorder 14 and through amplifier 15 to amplitude discriminator 16. A gate 17 passes the sea-bed echo signal to trigger circuit 23 which provides a suppression pulse for receiver amplifier 13, resulting in a "white line" in the recording of the sea-bed echo. Unit 18 blocks gate 17 during acoustic transmissions, and unit 19 blocks gate 17 immediately after passage of the sea-bed echo and until just before the next acoustic transmission. To ensure reliable operation of the sea-bed echo selection circuitry 16, 17, the gain of amplifier 15 is automatically controlled in accordance with the amplitude of the sea-bed echo by A.G.C. circuitry which may be that disclosed in Specification 1,147,192 (see Division H3). A gate 21, which is opened by a transmission pulse from unit 18 and closed by the sea-bed echo pulse from gate 17, passes clock pulses from oscillator 20 to counter 22 to provide a numerical sea-bed depth indication. False depth indications, due to operation of gate 21 by spurious signals, are accompanied by an interruption of the sea-bed "white line" and by the production of distinguishing marks 25, 26 in the recording. Additional monitoring of the depth indication is provided by superimposing it in analogue form on the recording. In the system of Fig. 3, the position of recording stylus (32) along the depth scale of recording chart (36) is represented on counter (40) which counts pulses produced by an optical resolver (37) coupled to the stylus drive belt (33). When this position corresponds to the sea-bed depth indication on counter 22 a pulse from coincidence gate (41) is applied through unit (42) and the receiver amplifier 13 to produce a mark on the chart. Provision may be made for off-setting the mark along the depth scale. The depth indicated by counter 22 is changed only when it has been transferred to a tape printer. In a further monitoring system (Fig. 4) the depth indication on counter 22 is read back from a printed tape, converted by units (46) and (55) to analogue form and compared in unit (56) with the position of recording stylus (32) as derived from an optical shaft position encoder (52) and code-to-analogue conversion units (53, 54). The output of unit (56) drives a servomotor (51) which positions a second recording stylus (49) for marking the indicated sea-depth at or offset from the position of stylus (32).
