Title: Microphone with non-rigid vibrating diaphragm
IPC: H04R7/06
Filed: 1924-04-07
Abstract: 214,609. Soc. des Etablissements Gaumont. April 18, 1923. Microphones; diaphragms.-The diaphragm of a microphone is made of supple material not under tension, so as to be free from resonance, and the resistance material consists of powdered anthracite. A felt block a is cut into the form of a six-spoked wheel to form chambers x which are filled with powdered anthracite capable of passing through a sieve with 80 to 100 meshes to the square centimeter. The diaphragm e is of pure silk muslin coated with rubber, to which is applied, before vulcanization, a sheet of gold leaf or other non-oxidizable and non-sulphurable material. Alternatively, the diaphragm may be of thin unsized paper, india-rubber, gutta percha or other pliable substance. This diaphragm is clamped over the mouth of a metal casing d by means of a split ring l which is sprung into position, a brass disc f being interposed. The diso is cut away at g, Fig. 2, and under the remaining parts h are fixed strips i of rubber .6 m.m. deep and formed with an edge of 30‹ against which the diaphragm rests. Current enters and leaves by the terminal rods n, p, of which the former is insulated by a sleeve o and communicates with a carbon block b supporting the granules, while the rod p communicates with the metal casing d. The active part of the diaphragm has a diameter of 44 mm., but in a modification suitable for use with amplifiers by a person standing at a distance the diameter may be increased to 100 m.m. with a corresponding increase in the number of granulechambers x.

Title: Improvement in high vacuum distillation process and apparatus
IPC: B01D3/10
Filed: 1945-04-10
Abstract: <PICT:0594900/III/1> A process for the high vacuum distillation of a thermally decomposable substance comprises subjecting the substance to high vacuum distillation in a still while flowing over a vaporising surface in the form of a thin film and recovering the heat from the undistilled residue while the residue remains in the still, and conveying the <PICT:0594900/III/2> <PICT:0594900/III/3> recovered heat to the incoming distilland within the still while the latter is in the form of a thin film under vacuum.  The still may comprise a casing 16 having a concentric vertical cylinder 12 down which the liquid to be distilled flows in film form while being heated by wire 11.  A coiled pipe 34 at the top and coil 36 at the bottom of the cylinder connected together and to a circulating pump 42 by conduits 38, 40 and 44 carry liquid for transferring recovered heat to the incoming distilland. Alternatively, a coil conveying a heating medium heated externally may replace the heating element 11.  Undistilled liquid collects in the collar 26 and the still is evacuated through the conduit 24.  The vaporising surface may be a circular shallow cone-shaped plate 80 (as shown in Fig. 3) which rotates about a vertical axis, the distilland being introduced on the centre of the plate and forced outwards by centrifugal force.  Helical coils 92 and 94 are connected to a circulating pump 98, and make thermal contact with the central and outer portions of the plate respectively for supplying recovered heat to the incoming distilland.  In the modification shown in Fig. 4, distilland is delivered from a pipe 150 on to the inside upper wall of a rotating cone 132, provided with gas outlet perforations 142, 144 and heated by a resistance wire 106 having a reflector 108.  The stationary cylindrical condensing surfaces 156, 158 and 160, cooled by means of internal coils 168, 170 and 172 are situated within the evaporating surface.  Heat exchange coils 152 and 154 on the inside upper and lower walls of the conical surface supply recovered heat to the distilland.

Title: Improvements in and relating to the electrical indication of engine cylinder pressures and other variations
IPC: G06G7/184
Filed: 1935-03-21
Abstract: 453,887. Valve circuits. BEALE, E. S. L., 44, Markham Square, Chelsea, London, and STANSFIELD, R., 16, Avenue Road, Teddington, Middlesex. March 21, 1935, Nos. 8899 and 11278. [Class 40 (v)] The wave-form of an electric current or voltage is integrated or differentiated by means of a resistance and inductance in series and of a feed-back circuit which compensates for the errors that would otherwise occur. The invention is applicable to the control of oscillographs in accordance with the variations of engine-cylinder pressures, valve motions, fuel-line pressures, vibrations of engines, changes in width and length of threads and wires and to like purposes, the current or voltage being derived from a piezo-electric crystal, an electromagnetic instrument associated with a flexible diaphragm or other moving part, or a carbon pile. The voltage derived from a detector of the above kind is developed in a coil 5 and applied to a valve V1 which is coupled through a large condenser 2 and high resistance 3 to the input terminals A, B, of a simple integrating circuit comprising a high resistance R1 and a small condenser C1. The voltage tapped off the condenser C1 at the output terminals C, D, is roughly proportional to the integral of the input voltage, but is subject to errors due to the fact that the impedance of the condenser Cl is not negligible in comparison with the resistance R1. In order that these errors may be neutralized, the output from the terminals CD is fed to a second valve V2 having a high resistance R2 and low resistance R3 in its output circuit; and the voltage tapped from the resistance R3 is fed back through a large condenser C2 to a low resistance R4 so arranged that the fed-back voltage is added to the voltage in the coil 5 for application to the first valve V1. The condenser C2 and resistance R4 are for stabilizing the valve by filtering and high-frequency oscillation. In modifications the resistance R1 and condenser C1 may be replaced by an inductance and resistance for integrating, Fig. 3 (not shown), or by a resistance and inductance or condenser and resistance for differentiating, Figs. 4, 5 (not shown).

The transmission cable is moved by a crank handle and has a projection 10 that extends through a slot in the portion 11 to move a device 5; the window being attached to the device 5 which slides on the guide rail. In the embodiment shown in Figs. 1, 2 a strap 12 links the tube to one end of the rail although tube and rail could alternatively be directly joined, for example by spot welding. The connecting piece 14 is injection moulded in one piece from polyamide 6 and has resilient arms 15 which grip the tube. A flexible extension 18 is slidably received behind a lug 21 pressed out of the guide rail and the tube can thereby move toward or away from the rail or, by bending of extension 18, move into or out of the plane of Fig. 1. Fig. 5 shows a second embodiment of connecting piece 14'; this is also a one piece injection moulding of polyamide 6 and, as well as resilient arms 15' gripping the tubes, has an elongated projection 24 whch is loosely received in an aperture 26 in a bridge piece 27 to which the guide rail is attached. The aperture 26 is elongated in a direction to allow movement toward or away from the guide rail and a head portion 25 of the connecting piece is elongated in a direction at right angles to the elongation of the hole to be retained in it. In the case where the rail and tube are directly connected at. the: other end of the rail the aperture 26 could be formed in a portion of the guide rail itself. In the form of winder shown in Fig. 1 the window is pulled up by the cable and the connecting piece is at the lower end of the rail, however in another embodiment, (Fig. 4 not shown) the cable pushes the window up and the connecting piece is at the upper end of the rail.

Abstract: 924,694. Recording gramophones. C. W. CLARK. March 23, 1962 [March 13, 1961; Aug. 17, 1961], Nos. 9174/61 and 29753/61. Class 40 (2). A booth-mounted recording machine for public use has recording and playback heads 24, 25 mounted on a common carriage 26 which in a single traverse successively indents and plays back a recording on a deformable plastic disc on a turntable 7. During the recording phase, the playback arm is held out of operative position by an arm lever 47 and a fixed cantilever 48. At the end of the recording period, as indicated by means 91, an overdrive motor M0 and freewheel mechanism 44 momentarily drive lead screw 35 at a higher speed to provide a run-out groove after which cam means C rocks the carriage 26 sufficiently about a guiderod 31 to raise the recording stylus clear of the blank. Upon the leadscrew drive being resumed by belt means 38 associated with the turntable, the amplifier is connected to head 25 (which has by now cleared the cantilever 48) to play back the recording. After playback, a turntable clamp 12 is released by solenoid means 71 and a <SP>1</SP>/ 3  rotation of a 3-hole plate 52, of blank thickness, moves the recorded blank to a delivery shoot 51 while a new blank is fed from a stack M to the turntable, in readiness for the next recording, the carriage being further rocked by the means C to disengage the playback head 25 and the carriage from the lead screw for return to the initial position by associated linkage (Fig. 7, not shown). The form and mounting of the recording stylus are described and the booth is preferably heated to a preferred recording temperature. The apparatus is normally coin-freed. In a further embodiment (not detailed), a record blank is used as a check and inserted to free the machine. In a further embodiment (Provisional Specification 9174/61), conventional cutting means are used in recording, the swarf being removed by vacuum means (not detailed). However, the indenting method is stated, in the present application, to offer reduced fire hazard.

Title: Method of detecting newly occurring defects in container linings
IPC: G01N27/24
Filed: 1976-03-09
Abstract: 1499632 Detecting faults in container linings EISENWERKE KAISERSLAUTERN GOPPNER GmbH 9 March 1976 [12 March 1975] 09339/76 Heading G1N A method of detecting a defect in the lining of a container filled with an acid or alkaline medium 4 involves detecting a variation in the impedance between the container and an electrode 5 immersed in the medium by means of an A.C. energized bridge (1 kHz-30 kHz) in the arm of which the impedance is connected. Occurrence of a defect causes unbalance in the bridge and the resulting output voltage is fed via differential amplifier 17, rectifier 18, threshold device 19, and switch 20 to an alarm system 21. In an alternative embodiment, Fig. 3 (not shown), compensation may be effected for variations in the electrical characteristics of the medium by use of a second electrode (24) immersed in the medium and connected in the bridge. The variations of the electrical characteristics vary both impedances equally but occurence of a defect affects the impedances differently due to the differing geometrical configuration so the bridge becomes unbalanced.
