Title: Arrangement for testing an electrical gyroscopic firing apparatus also intended for practice purposes and provided with means for automatically indicating the result of the testing operation
IPC: F41G5/26
Filed: 1920-07-02
Abstract: 146,328. Krupp Akt.-Ges., F. Jan. 2, 1919, [Convention date]. Ordnance, discharging Ly means external to breech mechanism.-Relates to apparatus for automatically indicating the result of a test or practice with gyroscopically-controlled electric firing- gear, and consists in mounting the registering member on the gun breech. The automatic firing apparatus consists of a gyroscopically-controlled sighting-telescope C<3> and electric contact c<4> mounted within a casing C which carries an electric contact c' and is mounted on an arm B adjustable on the gun trunnion a<2> for elevation by a worm-gear a<1>, b<1>. When a firing test is in progress the terminals x are placed in the cups y and the contacts c<1>, c<4> are then in circuit with a firing-switch G, a firing-magnet a<3>, and a damping-motor D. The result is recorded, on paper wound on a drum P adjustable on a slide M, Fig. 1, by a pointed member K, Fig. 3, which is freely mounted in a rod h<1> so as to be thrown rearwards against the drum when an arm a<12> is attracted by the firing- magnet a<3>. The apparatus is first set up as shown in Fig. 2 to measure, by means of a chronograph R and interrupter switch Q, the delay which occurs between the closing of the switch G and the actuation of the member K. The chronograph consists of a solenoid-controlled stylus r<3> marking a line r<8> upon a band passing over rollers r<1>. The gun being elevated until the point K registers with the end q<5> of the lever q<3> of the interrupter Q, the switch G is closed, the armature r<6> carrying the stylus r<3> is raised, and a line r<9> is marked on the band until the armature r<6> is returned by the break in the circuit which occurs when the point K contacts with the part q' of the interrupter Q. The springs E, J controlling the pointed member K are now adjusted until the delay, which is measured by the length of the line r<9>, is equal to the total delay which occurs when firing live ammunition. To carry out a firing test, the interrupter Q is replaced by the drum P on which a zero-line is made by a stylus n<1>, which line exactly registers with the member K when the gun has the desired elevation. The contact c<4> is automatically adjusted in known manner to correct for speed of rolling and total delay, and the arm B and its contact c<1> are adjusted by hand to suit the desired gun elevation, the switch G is then closed and the gun-elevatiing gear set in motion at constant speed. When the contacts c<1>, c<4> come together and after the appropriate delay the point K indents the drum on the zero-line if the apparatus is free from error.

Title: Improvements in or relating to the manufacture of filaments, foils and other structures from viscose
IPC: D01F2/06
Filed: 1938-06-20
Abstract: 501,495. Viscose; artificial silk, films, &c. SCHLESISCHE ZELLWOLLE AKT.-CES. June 20, 1938, No. 18301. Convention date, June 19, 1937. [Class 2 (ii)] Carbon disulphide is caused to act on alkali cellulose in the presence of a higher fatty alcohol, that is, a monohydric aliphatic alcohol immiscible with or insoluble in water, e.g., lauryl, stearyl or oleyl alcohol. The xanthogenate furnishes a thinner viscose, so that the ripening of the alkali cellulose may be shortened or dispensed with. Filaments, foils and other shaped structures may be made from the viscose. In the case of artificial silk and cellulose wool, the products have a good feel and show both spiral curling and irregularities on the surface. The Specification as open to inspection under Sect. 91 refers also to the use of castor oil and pine oil instead of the higher fatty alcohol. This subject-matter does not appear in the Specification as accepted.

Title: Gas turbine engine
Inventor: MCCARTHY DENIS
IPC: F01D11/02
Filed: 1967-04-20
Abstract: 1,131,883. Gas turbine engines; axial-flow compressors. ROLLS-ROYCE Ltd. April 20, 1967. No. 18304/67. Headings F1C, F1G and F1T. A gas turbine engine comprises a rotatable assembly mounted in a thrust bearing with freedom of limited axial movement, the rotatable assembly having a part with a substantially axially facing surface which defines with fixed structure a chamber to which fluid under pressure from the fluid-flow duct is supplied, and a variable flow restriction which is variable in response to axial movement of the rotatable assembly controls the pressure in the chamber. In the gas turbine engine shown, air is bled from the delivery end of the compressor 11 via one or more apertures 32 and supplied via an axial labyrinth seal 33 to a chamber 31 formed between a turbine rotor disc 15 and a fixed wall 27. The air escapes from the chamber 31 via a radial labyrinth seal 30 and enters the turbine flow duct downstream of turbine nozzle guide vanes 26; the rate of flow of air can be arranged to be adequate for cooling purposes. Axial displacement of the shaft 16 due to inbalance between the end thrusts of the compressor 11 and the turbine 13 varies the flow restriction presented by the seal 30 and therefore varies the air pressure within the chamber 31 in the sense which opposes the inbalance. The outer race 22 of thrust bearing 20 is loaded by one or more springs 25 or hydraulically actuated pistons to provide a substantially constant axial load on the bearing. Instead of being applied to a turbine rotor disc 15, the invention may be applied to a compressor rotor disc.

Abstract: 1,082,610. Analogue-to-digital converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 27, 1966 [June 1, 1965], No. 18335/66. Heading G4H. An analogue-to-digital converter of the successive approximation type includes a register 12, a precision power supply 11 generating a reference signal, a resistor network 6 switched by the register to produce a corresponding analogue signal which is applied at a summing junction 7 together with the input signal 5, the output of the junction being applied to a comparator 9, the reference voltage of which is derived from a circuit 10 having switching means connecting either to ground or to the reference signal from 11 according to the sign of the unknown input signal. The reference signal has a value of - 1 volt. The input 92 of comparator 9 is normally connected to ground. If the input 5 is positive, in the initial cycle of operation, the input 91 is positive relative to input 92 and the comparator output 93 does not affect the sign circuit 13. If the input is negative, the input 91 is the more negative and the output 93 switches the sign circuit. This then enters a negative sign bit in the register 12 and switches contact 103 to connect to the reference signal from generator 11. The input 92 then changes from zero volts to a value of - 1 so that the origin for the subsequent operation of the digitizer is changed to - 1. The final value in the register 12 is then the 2's complement of the value of the input signal at 5.
