Abstract: 574,871. Catalytic heaters. FRIGIDAIRE, Ltd., KENNINGTON, W. 0., WHALLEY, E., and SINCLAIR, A. J. Oct. 12, 1942, No. 14289. [Classes 75 (i) and 126] A catalytic heater comprises a mass 4 of platinized asbestos or other catalyst held in position by two vertical cylindrical mesh-like or perforated supports 5, 6 mounted above a base plate supported on the fuel container 1 by air deflectors 2. The inner support 5 forms the vertical wall of a vaporizing chamber 7 from which wick tubes 3 extend downwards into the fuel container 1. The outer support 6 is surrounded by a removable air deflector 11 around which is provided an outer casing 12 secured by pegs 18 to supports 17 pivoted to the fuel container. Combustion is started by burning volatile fuel at an annular pad 13 on the base plate. The air rises through inlets 10 in the base plate and divides, part passing between the burner 4 and deflector 11 and part passing between the deflector 11 and casing 12 to a chimney 16. When combustion is to be stopped the casing 12 is lowered to prevent the flow of air for combustion. In the lowered position pegs 19 on the casing engage the supports 17. The heater may be transported by means of a handle ring 22 to which chains carrying retainer pins for the pegs 18, 19 are anchored. The top of the chamber 7 is formed as a pan 23 in which condensed fuel evaporates.
Patent GB-229919-A (GB)
Title: Improvements in and relating to the measurement of frequency of electric currents
IPC: G01R23/02
Filed: 1924-06-13
Abstract: 229,919. Mallett, E. June 13, 1924. Frequency, measuring.-The frequency of a current traversing an inductance coil L, is measured by coupling with this coil and oscillatory circuit L2, C2, Fig. 1, of known natural frequency, or with a mechanical vibratory member T, Fig. 3, of known natural frequency, and determining change in impedance of the coil L, at the resonant frequency. This may be determined bv an ammeter in the circuit of the coil L, which may be calibrated to indicate variations in frequency from the resonance value or actual frequency values or may record these values automatically. The inductance L2 and condenser C2 may be variable so that the value of the resonant frequency may be adjusted to any desired value. Similarly the natural frequency of the vibrating member T, Fig. 3, may be varied by altering the point at which it is clamped. This member may be a tuning-fork of magnetic material, preferably, permanently magnetized or may be a tuning-fork or reed of copper or other conductor and caused to vibrate by eddy-currents, or a mice reed coated with tinfoil may be employed, the coupling in this case being electrostatic. Instead of employing an ammeter, the change in impedance, may be measured bv determining the change in potential across coil L1 which is connected across the mains in series with a high resistance. An alternating-current voltmeter may be employed, or a crystal, or valve rectifier used in conjunction with a continuous-current instrument.

Title: Improvements in and relating to sound reproducing devices
IPC: H04R7/12
Filed: 1929-05-08
Abstract: 333,280. Poupard, C. H., and Welch, A. P. May 8, 1929. Diaphragms; magnetic instruments.-A moving coil sound-reproducing device comprises a metal diaphragm and coil-supporting extension made in one integral piece without seams, joints or overlaps. The diaphragm and extension are preferably formed from aluminium or aluminium alloy by pressing between dies, spinning or by electrodeposition or coating. Fig. 1 shows a construction employing a conical diaphragm 1 integrally provided with a coil-supporting extension 2, the coil 7 being wound on a portion 4 between shoulders 5, 6. In the modified construction, Fig. 2, the reduced portion 4 extends to the free end of extension 2, the coil being held against shoulder 5 by a sleeve 8 having an inturned flange 9. If desired, the coil may be fixed to the internal surface of the sleeve or may be wound on the exterior of a sleeve adapted to fit within an extension of the diaphragm. The extension and sleeve function as a short-circuited turn of the coil. The diaphragm may be formed with circumferential, radial or other corrugations and the extension 2 may also be stiffened by the provision of corrugations, ribs or recesses. The diaphragm, extension 2 or sleeve 8 may be formed, as by pressing, with integral lugs or clips for securing the coil leads. Various means are described for attaching the marginal portion 3 of the diaphragm to a flexible suspension. Thus the portion 3 may be pierced with holes for use with a thread or like suspension or its surface may be roughened, as by perforating, for attachment of a flexible ring thereto by adhesive. Fig. 6 shows a modification in which the portion 3 is formed with radial slots 13 terminating in holes 14, the alternate portions 15, 16 thus formed being bent in opposite directions and a flexible suspension ring applied therebetween and attached to the diaphragm by pressing the portions 15, 16 flat. Alternatively, the flexible ring 17 may be gripped by a flanged over portion 18 of the diaphragm as shown for example in Fig. 8. According to further modifications, the diaphragm may be formed adjacent its periphery with circumferential corrugations or may be made of less thickness so as to be itself sufficiently flexible or it may be integrally formed with radial or other extending suspension strips or ligaments. A thread suspension may be employed for both the diaphragm and extension 2.
