Filed: 1957-08-23
Abstract: 856,052. Automatic brake application. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and ROBERTS, L. J. Aug. 22, 1958 [Aug. 23, 1957], No. 26688/57. Class 103 (1). A vigilance control apparatus for railway vehicles in which too great a fall in the pressure in an alternately charged and discharged timing reservoir sets in progress a sequence of emergency operations, includes an electromagnetically-operated valve establishing or interrupting the connection of the reservoir with a charging source, pressure switch means responsive to a predetermined high-timing reservoir pressure to break contacts thereof, cancelling switch means operable manually either directly or through the existing driving controls to make contacts thereof, and a holding circuit arranged to maintain the electromagnetically-operated valve energized in response to operation of the second said means until the first said means is operated. The electromagnetic valve 14 controls the connection of timing reservoir 11 with a charging source via choke 12 and with atmosphere via choke 13. The sequence of emergency operations ending with brake application is as described in Specification 856,051. The holding circuit comprises a coil 15 of valve 14, pressure switch 16 and the contacts and coil 18 of relay 17; a control circuit comprises a coil 21 of relay 17 and the following cancelling devices: a deadman's switch 22 in series with contacts 23 controlled by a reverser key of the master controller; two push-buttons 24, 25; and contacts 26, 27 on the master controller handle and operated by movements of the handle; the deadman's switch is shown in the release position and the contacts 23 are broken when the reverser key is in the neutral position. To charge the apparatus or recharge it in response to a warning denoting the initiation of the emergency operations, one of the contacts 24 to 27 or contacts 22 and 23 is or are made to energize coil 21 to operate relay 17 and energize the holding coil 18 and valve 14 until pressure in reservoir 11 is sufficient to operate switch 16 to break the circuit. A switch responsive to brake cylinder pressure is connected either at 28a or 28b to ensure energization of valve 14 during braking to maintain reservoir 11 fully charged and preventing operation of the emergency sequence. The relay 17 is modified in Fig. 2, not shown, and includes a single coil which when energized by the closing of any of the contacts 22-27 causes relay 17 to make two sets of contacts, one set in the holding circuit including the single coil and switch 16 and the other in the circuit including valve 14. Specification 856,053 also is referred to.

Abstract: 390,175. Microphones. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Flanders, P. B. ; 28, Prospect Street, East Orange, New Jersey, and Harrison, H. C.; 94, Bayview Avenue, Port Washington, New York, both in U.S.A.) Sept. 29,1931, No. 27160. Convention date, Oct. 20, 1930. [Class 40 (iv).] An electrostatic sound translating device of such size as to produce a negligible disturbance in the sound field is provided with a diaphragm which is tensioned in known manner by means external to the instrument and clamped thereon by means of a ring which is made so thin as to produce practically no undesirable cavity resonance within the useful frequency range of the device. The width of this clamping ring is also made as ,small as possible so that the free diameter of the diaphragm is as near as possible the diameter of the housing. Fig. 1 shows a construction of condenser microphone comprising a metal casing 4 carrying an internal steel ring 5 which forms a seat for the back electrode structure 6. This structure consists of a steel plate 7 and steel member 8 secured by a screw 20 on opposite sides of an insulator 9 which is formed with a slot to provide an air leakage path The diaphragm 10, tensioned to between 16,000 and 40,000 lbs. per square inch, is secured on the surface 12 of the casing 4 by the clamping ring 11 which is only of sufficient size to maintain the tension. Accurate adjustment of the spacing between the diaphragm and the front surface 18 of electrode 7 is obtained by assembling the device without inserting the washer 19, which is of a thickness equal to the desired electrode spacing, lapping the surfaces 12, 18 until they are in exactly the same plane and then inserting the washer 19 when finally assembling the device.. The electrode 7 is cut away at the back so as to leave a spider-like construction of arms 13 and excessive damping at high frequencies is prevented by forming a single circular groove in the electrode face with openings 15 in the relatively thin portions of the electrode between the arms 13. An equation is given in the Specification setting out the preferred ratio of the radius of the electrode 7 to the radius of the free portion of the diaphragm. Fig. 2 shows the microphone 1 connected by a tube 2 to an amplifier 3 as described. in Specification 375,251, the tube being used as one lead whilst the other consists of a wire 16 held in the tube by insulating spacers 17. Specification 134,872, [Class 40 (iv), Telephones &c.], also is referred to.

Title: Improvements in or relating to the purification of gas mixtures
IPC: B01D53/86
Filed: 1958-08-27
Abstract: The concentration of nitric oxide in a gas mixture is decreased, at least to a level at which any NO still remaining is not deleterious in use, by mixing ClO2 with the gas mixture to oxidize NO to NO2. The gas mixture may be town gas, producer gas, coke oven gas, coal gas, "convert gas," or flue gas.  The ClO2 may be prepared by passing Cl2, preferably diluted with a carrier gas, e.g. N2, through an aqueous solution of sodium chlorite.  The gas mixture may be scrubbed with water under pressure before contact with ClO2 to remove CO2. After such contact, the gas mixture may be scrubbed with an aqueous alkaline solution (of pH greater than 7), eg. aqueous NaOH, or an aqueous alkaline reducing solution of sodium sulphite, or sodium thiosulphate, to remove NO2, Cl2, and chlorine compounds.
