Abstract: 575,281 . Gyroscopic apparatus. BARNES, J. W. May 31, 1938, No. 16262. [Class 97 (iii)] [Also in Group XXXV] To maintain the rotor speed proportional to the air speed in gyroscopic apparatus for giving a vertical datum on aircraft during curved flight, the electrically or pneumatically. driven rotor 1, which is mounted in a pendulous support 2, drives an air pump 5, 6, for applying pressure to one side of a diaphragm 12, which is open to atmospheric pressure on the other side, the difference between such pressures being opposed by the difference between the impact pressure and static pressure of a pitot head. The movements of the diaphragm control electrical or pneumatic means for regulating the speed of the rotor. As shown, the diaphragm 12 is connected by rod 14 to two equal diaphragms 11, 13 of smaller area than diaphragm 12. The impact pressure is communicated via tube 19 to one side of diaphragm 13 and the static pressure via tube 18 to one side of diaphragm 11. The rod 14 forms part of a contact 16, 17 for a relay 20 which short-circuits a resistance 21 in the driving circuit for the rotor whenever the rotor speed, and therefore the pressure of pump 5, 6, falls. When the rotor is air driven, the diaphragm unit may control a valve for the driving air either directly or electrically.

Title: Amplitude stabilized sawtooth current generator
IPC: H03K4/54
Filed: 1960-05-09
Abstract: 894,326. Transistor sawtooth generating circuits; cathode ray tube circuits. SYLVANIA ELECTRIC PRODUCTS Inc. May 9, 1960 [May 7, 1959], No. 16373/60. Classes 40(6) and 40(7). The sawtooth current generated in aninductive load is maintained constant in amplitude despite changes in frequency by means of a series transistor arranged to pass a constant emitter-collector current. The Figure shows a blocking oscillator transistor T1  having a feedback transformer AT, an output coil 2, a monitoring resistor 32 and a by-pass capacitor 20. During the conducting phase the transistor passes a steadily increasing current through the output inductor until at a value determined by resistor R1 the transistor ceases to be saturated whereupon by regenerative action the transistor is switched off and then on again producing the flyback. Adjustment of R1 varies the frequency oscillation and accompanying variations of amplitude are prevented by connecting in series with the collector circuit of a transistor T2 arranged to pass a constant current. The magnitude of this current and thus the amplitude of the sawtooth output wave may be varied by means of resistor R2 or modulated by source 53.

Abstract: 707,250. Speed governors. C.A.V., Ltd. July 10, 1952 [July 11, 1951], No. 16409/51. Class 57 A diaphragm or piston b connected to the control rack a of a fuel-injection pump is subjected to pressure in the chamber c connected by pipe d to the engine side of a manually-actuated throttle f in the air manifold e. A cylinder g is connected by pipe p to the intake side of the throttle f and is also in communication, through ports j, controlled by the valve i, with the chamber c. The valve i is loaded by a light spring m engaging an abutment n, having through passages and loaded by a stronger spring o. At low speeds, when the throttle is closed, the diaphragm abuts and opens the valve i against the light spring m to permit atmospheric pressure to bleed into the chamber c and stabilize the action of the governor. At high engine speeds under light load, when the throttle is open, the diaphragm moves the valve into contact with the abutment n and damping is effected by the strong spring o, the atmospheric bleed being ineffective when the throttle is open. The pipe p may be provided with a rotary valve movable by the throttle as described in Specification 697,806. Specification 653,586 also is referred to.

Title: Process for the production of valuable liquid hydrocarbons from hydrocarbon mixtureswhich contain unsaturated compounds
IPC: C10G45/34
Filed: 1934-06-02
Abstract: Hydrocarbon mixtures containing unsaturated compounds, e.g benzines obtained by cracking are purified from sulphur and freed from unsaturated compounds containing two or more double bonds by treatment with hydrogen at temperatures below 300 DEG  C. in presence of one or more of the sulphides of iron, zinc, manganese copper and tin.  The reaction is preferably carried out at temperatures between 180 and 250 DEG  C. and under pressures above 20 atmospheres. A strongly unsaturated benzine obtained by cracking which while having a good octaine number produces strong resinification when used in a motor, is passed at 200 DEG  C. and 200 atmospheres pressure with hydrogen over precipitated iron sulphide as catalyst.  The product while still unsaturated and having the same octane number is free from resinifying constituents.  Hydrogenating gases comprising hydrogen mixed with nitrogen, water gas, carbon dioxide, sulphuretted hydrogen water vapour or methane may be used.
