Abstract: 1,041,771. Valves. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 5, 1962 [Dec. 6, 1961], No. 43714/61. Heading F2V. [Also in Division G3] Sluggishness in a piston pressure control valve having a conical obturating portion is eliminated by rotating the piston within the valve chamber by providing the inlet tangentially to the piston. The magnitude of a pressure signal PS<SP>1</SP>, with respect to a datum pressure Pi, is determined by the vertical movement of piston 1 within chamber 5 and is derived from inlet pressure PS upon the valving action of conical portions 2 and 3 of the piston I at inlet chamber 7 and outlet chamber 9 to atmosphere. A feedback pressure FB is applied through opening 11 to piston end space 12. A transparent window 21 permits observation of the piston rotation.

Abstract: 437,360. Ticket - issuing apparatns. MOLLER, J. G. C., 5, Fredrik Stangsgate, Oslo, Norway. Jan. 26, 1934, No. 2788. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 30, 1934]. [Class 106 (iii)] A railway &c. ticket is punched or cut in a selected place, is moved into contact with a value printing disc and the destination is typed thereon. The ticket B is placed in a holder 2 on a pivoted arm 3 which, after the edge of the ticket is cut, moves upwardly so that the valve is printed by the edge of the previously set printing disc 1. The destination is typed by type bars 7 of the typewriter 6. The edge of the cutter is clipped by a cutter 14 slidable in a pivoted arm 13 and moved downwardly by a cam on the shaft 16 which is rotated by an arm 22. The arm 22, shaft 16 and pivoted arm 13 are adjust. able laterally to any of several cutting positions. A spring 19 normally holds the arm 13 back against a stop 21, but it is moved into the cutting position by a cam 20 on the shaft 16.

Title: Piezoelectric resonator circuit component
IPC: H03H9/56
Filed: 1970-09-16
Abstract: 1332141 Electro-mechanical filters VERNITRON CORP 16 Sept 1970 [10 Oct 1969 24 June 1970] 44333/70 Heading H3U [Also in Division H1] A piezo-electric circuit component comprises a wafer on which electrodes are formed to produce resonator elements in association with capacitative elements formed by depositing opposed electrodes on an area of the wafer which is not active piezo-electrically. The wafer 12 (Fig. 3) is of ceramic material in which by application of a high D.C. electric field the area 12a is rendered active piezo-electrically (poled) and on which two pairs of electrodes 18, 20 and 22, 24 co-operate with the respective counter electrodes 19 and 23 to form two isolated pairs of coupled resonators. Acoustical isolation may be achieved by providing damping material 58, 80 between the sections or by suitable spacing of the electrodes. The filter sections are electrically coupled by an integrally-formed capacitor formed on the unpoled region 12b of the wafer between the opposed electrodes 25 and 26. 30 and 32 are the input and output leads and the common external lead is applied to electrode 25 which is integral with the counter electrodes 19 and 23. The vibratory modes are generally thickness shear or thickness extensional and the wafer 12 can be made from a natural piezoelectric crystal or from a polarizable ferroelectric crystal or ceramic material. With a natural piezo-electric crystal e.g. quartz, the unpoled region 126 does not exist and damping is utilized to prevent the capacitor region 26 exhibiting a piezo-electric response near the passband of the filter. Further circuit elements may be added to the wafer such as the resonator section formed by electrodes 34 and 34<SP>1</SP> which is acoustically isolated from the filter sections and can act as part of a discriminator in an FM receiver. The area of electrodes 34, 34<SP>1</SP> relative to the electrode area of the filter resonators is chosen such that the centre frequency of the filter pass-band falls mid-way between the resonance and anti-resonance frequency of the discriminator resonator. In Fig. 8 a polycrystalline non-ferroelectric material e.g. cadmium sulphide, cadmium selenide, beryllium oxide, wurtzite zinc sulphide or zinc oxide is formed as a layer 66 on a substrate which may be of piezo-electric material e.g. quartz or non- piezo-electric material e.g. glass.

Dust is extracted by a fan 62 from the grinder 1 and its hopper 60. Dust from hopper 32 of the pulverizer 14 is exhausted by operation of the pulverizer via a hose 67 into a bag filter 65 Fig. 2. Levels in the hopper 32 are sensed by level switches 83, 83' Fig. 2 and control the conveyor and pulverizer motors. These motors are stopped by limit switches LSI, LS2 of the weighing apparatus which determines the correct pulverized/virgin powder ratio. This ratio is adjusted by adjustment of weights 47, 48. The weighing devices are fed by screw feeders 34, 35 which convey pulverized and virgin material respectively from the hopper 32 or the virgin material hopper 33.
