Title: Improvements in or relating to apparatus for indicating vibration, particularly in internal combustion engine cylinders
IPC: G01H1/00
Filed: 1939-05-12
Abstract: 533,499. Electric signalling systems. RESEARCH CORPORATION. May 12, 1939, No. 14295. Convention date, May 13, 1938. [Class 40 (i)] [Also in Groups XXVII and XXXIX] Vibration indicating apparatus e.g. for indicating detonation in an internal combustion engine comprises an electromagnetic pick-up having one part connected to the vibrating body and elastically connected to a second part to provide a variable air-gap, the inertia of the second part and the elasticity of the connection being such that the voltage output of the pick-up is dependent on the vibratory acceleration of the body. The natural vibration frequency of the second part should be high compared to any applied frequency. Cylinder vibrations applied to diaphragm 3 vary the gap of an electromagnet pick-up 15 and the resultant voltage is amplified by valves 23, 25 and applied to a back-biassed valve 26 having a neon tube 30 in its anode circuit. The input circuit to valve 23 comprises a transformer 18 and condenser 22 which pass the normal range 5000-20000 # of detonation frequencies and the input circuit of valve 26 has a circuit 28 broadly resonant to the same range. The electromagnet comprises a core 11 and pot 10 clamped against the periphery of the diaphragm 3 by a shell 8 and screwed ring 13. In a modified arrangement of magnet and diaphragm described with reference to Fig. 2 (not shown), the electromagnetic structure is rigidly fixed to the cylinder, variation of the gap being produced by the centre of the diaphragm which is clamped at its edge between the said structure and the cylinder.
Patent GB-1307332-A (GB)
Title: Tape transport apparatus
IPC: G11B15/54
Filed: 1970-03-24
Abstract: 1307332 Automatic control of moving tape RECORTEC Inc 24 March 1970 [24 March 1969] 14308/70 Heading G3R In a tape transport system, the size of a tape loop is maintained constant by an electrical signal which controls the drive of two motors connected to feed and take-up reels respectively. In Fig.3, a spring-loaded roller 33 forms a loop 16' in recording tape 16 which may be moved in either direction between reels 11 and 12 driven by reversible or reversibly clutched motors 14 and 15 respectively. When a switch 31 is moved to the "forward" position a brake 37 is released and a positive voltage applied through an amplifier 26 to cause motor 14 to wind up tape on reel 11. The tape is moved at such a speed that the negative voltage fed back from tachometer generator 36 equals the positive voltage applied by switch 31. The consequent shortening of loop 16' allows more light to pass from lamps 23 to photo-cells 24 the voltage from which then exceeds that from a potentiometer 25' so that, through amplifiers 25, 27, 29, motor 15 is caused to unwind tape from reel 12 and thereby restore loop 16' to its proper length. Tape thus moves continuously from reel 12 to reel 11 at constant speed with constant tension. If switch 31 is moved to the "reverse" position, similar conditions obtain with the tape moving from reel 11 to reel 12. If error in the length of loop becomes excessive for any reason, the output from amplifier 25 applied through diodes 39 effects correction by controlling the speed of motor 14. This correction may alternatively be obtained from additional photo-cells at each end of chamber 19. Variations of loop length may alternatively be detected by a potentiometer or differential transformer operated by movements of roller 33. In a modification, Fig. 2 (not shown), the loop of tape is formed by a vacuum pump connected to chamber 19 and both motors are continuously controlled to maintain the loop length constant.

Abstract: 1380030 Coatings of porous silicon dioxide MERCK PATENT GmbH 26 March 1973 [27 May 1972] 14457/73 Heading C1A [Also in Divisions B1-B2] A coating of porous silicon dioxide is applied to a non-porous material by first coating the non-porous material with a polymeric alkoxysiloxane (obtained, e.g. by acidic hydrolysis of a tetraalkoxysilane, preferably of totraethoxysilane). The materials thus coated are subsequently subjected to a hydrolytic polycondensation by the use of an excess of water, preferably in the presence of hydroxyl ions, and are dried. The hydroxyl ions are preferably provided by ammonium or sodium hydroxide, an alkali metal salt of a weak acid, or an organic base. In the examples, glass spheroids with a diameter of 30-40 microns, aluminium shot, aluminium foil and a synthetic resin film are coated with porous silica.

Abstract: 110,212. Marsland, G. T. Oct. 23, 1916. Mechanical telegraphs; pneumatic and hydraulic telegraphs.-Relates to order telegraphs of the kind in which at least two sets of orders are transmitted and received, and the invention consists in a mechanism being provided for each set of orders, the mechanisms being geared together or otherwise interconnected so that all possible combinations of the orders of one set with the orders of another set can be transmitted by a single operating handle. Fig. 1 shows a transmitter face 1 with two dials 2, 3 having pointers 5, 13. The pointer 5 is moved directly by a handle 4, and motion is conveyed by a Geneva stop, and gearing if necessary, to the pointer 13 which moves through only one division of the dial for each complete revolution of the pointer 5. A single connecting member conveys the motion to the receiver, which is constructed similarly to the transmitter in order to reproduce the same signals. The single connecting member may be a line of shafting, or wire, &c., an hydraulic system, or an electric circuit. Means is provided on the receiver, e.g. a handle, for operating the connecting member to actuate a bell at the transmitting end in reply to a signal.
