IPC: B60Q1/34
Filed: 1927-06-01
Abstract: 281,477. Foote, A. A. June 1, 1927. Road-traffic signals on vehicles.-A direction indicator for use on vehicles comprises a movable member having openings through which light is projected so as to produce an enlarged representation of a selected signal upon a screen. In the arrangement shown in Figs. 1 and 2, the movable member consists of a drum segment, the faces e, h, k of which have cut-out portions representing signals. The sector is pivoted at d and is positioned against a spring s by a wire u connected to an actuating wheel x, Fig. 3. Light from a lamp b is projected through the selected opening, and an opening in a plate n, upon a screen o, r. The hand-lever v of the actuating wheel x may control the lighting of the lamp b by contacting with studs 2 in its different positions. A second wire may be provided for actuating a similar apparatus at the rear of the vehicle.

Title: Improvements in or relating to the electrolytic production of metals
IPC: C25C7/00
Filed: 1936-11-16
Abstract: 470,733. Electrolytic production of metals. DEUTSCHE GOLD-UND SILBERSCHEIDEANSTALT VORM. ROESSLER. Nov. 16, 1936, No. 31334. Convention date, Dec. 12, 1935. [Class 41] A process for producing metals, e.g. beryllium, thorium, aluminium, chromium, manganese and iron, by the electrolysis of molten metal salts is characterized in that electrolysis is first effected in one vessel, then after a considerable quantity of metal has been deposited the electrolyte is transferred to a second vessel where it is further electrolyzed the metal left in the first vessel is recovered, and the electro lyzed melt from the second vessel is returned to the first vessel where it is again electro lyzed. Fresh electrolyte may be added before each electro lysis. Electrolyte is passed from vessel I to vessel II by way of a pipe e and a vessel h containing a perforated drum i for collecting the metal. The pipe e may be closed by valves or by passing cooling liquid through a jacket f, thereby solidifying the melt. The drum comprises an insertion piece k enabling it to be inserted in a centrifuge where the metal is freed from fused salt and washed. The anode b is suspended from the cover c, and the wall a of the vessel I forms the cathode. The electrolyte may be a mixture of 55 per cent by weight of anhydrous beryllium chloride and 45 per cent by weight of common salt; aluminium chloride may be treated alone or with small amounts of conducting salts. The two vessels may stand side by side, electrolyte being siphoned from one to the other, or they may be suspended one at each end of a beam pivoted on a vertical standard. The electrolyte may be purified in a heat-insulated container between the two electrolytic treatments.

Abstract: 982,302. Producing electric oscillations. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 31, 1961 [Sept. 7, 1960], No. 31378/61. Addition to 961,550. Headings H3B and H3F. In an oscillatory circuit, having two stable phase conditions, of the type described in the parent Specification, the magnetic core consists of a thin magnetic film deposited upon a single conductor, and the circuit is also provided with biasing means. Two resonant circuits have a common inductance 16 and individual capacitors 17, 18 and thin film cores 12, 13. The circuits are tuned to resonate at a frequency 2f. An A.C. generator 14 supplies current at frequency f to sustain the oscillations in the resonant circuits in one of two phase conditions differing by #. D.C. windings 10, 11 produce longitudinal magnetic fields in the thin films and allow the films to be switched by lower currents in the resonant circuits. A bias on winding 10 allows oscillations of a first phase condition to be set up, while a bias on winding 11 allows oscillations of the opposite phase to be set up. The magnetic film may be formed by electrolytic deposition on the conductor.

Title: Improvements relating to controlling means for air-craft internal combustion engines
IPC: F02D1/00
Filed: 1939-12-04
Abstract: 537,027. High-pressure servomotor systems. C.A.V., Ltd., and EVANS, F. M. Dec. 4, 1939, No. 31387. [Class 135] In controlling means for aircraft internalcombustion engines of the supercharged or high compression types, in which an aneroid mechanism acts on a servomotor for actuating the throttle valve of the engine induction system, and in which the pilot's lever which can actuate the throttle valve can also vary the setting of the aneroid mechanism, means is provided whereby the output of the fuel injection pump is varied according to the setting of the aneroid mechanism. As shown, a bellows p in a chamber r connected to the induction pipe x operates the valve o of a servomotor through a lever z. The piston i of the servomotor is connected to the throttle valve b through rod and links h, g, c, a. The chamber r is separated from a chamber r<SP>1</SP> by a diaphragm s carrying the bellows p and the chamber r<SP>1</SP> is open to the atmosphere or is connected to the engine exhaust pipe. The pilot's lever f acts on the throttle valve b through links e, c, a, and also on a movable post 2 to which the link z is pivoted through links d, 6, 5 and cam 4. The above subject-matter is described in Specification 537,026. According to the present invention the lever 5 has a second cam 7, and this cam acts on a bell-crank lever 8 and link 9 to move the control rod 10 of the fuel injection pump 11. Thus, movement of the pilot's lever f to increase the opening of the throttle valve b will increase the supply of fuel and vice versa.

Abstract: 896,505. Fluid-actuated valves. MASSEYFERGUSON (UNITED KINGDOM) Ltd. Oct. 2, 1958 [Oct. 10, 1957], No. 31666/57. Class 135. [Also in Group XXXI] Acceleration of an hydraulic ram 15, Fig. 4, in a tractor power-lift system are restricted by a slow-opening valve 80 which limits the rate of change in the flow between a pump 10 and the ram 15 independently of the pressure in the system. The valve 80 comprises a piston 84 loaded by a spring 89 to engage a valve seal 88 between the inlet and outlet ports 81, 82. Leakage flow through the piston 84 is permitted by small bore passages 86, 87 and in the event of a pressure build-up at the inlet 81 resulting from closure to exhaust at a control valve 20 the leakage flow permits the piston 84 to move at a predetermined rate to give the desired rate of increase of flow at the seat 88. Return flow to exhaust from the cylinder 15 is permitted by a non-return valve 91 which may be replaced by a second valve similar to the valve 80 for restricting the return flow.

Title: Method for seismic surveying
IPC: G01V1/38
Filed: 1972-07-06
Abstract: 1402343 Seismic exploration PETTY-RAY GEOPHYSICAL Inc 6 July 1972 [19 Oct 1971] 31733/72 Heading H4D Multiple coverage of reflection points along a traverse is obtained at a higher-than-usual average speed by advancing a seismic detector spread along the traverse at a first speed while actuating a source at successive locations in a group of source locations along the traverse, then advancing the spread at a faster speed without source actuation, then advancing the spread at the first speed again while actuating the source at successive locations in a second group, and so on. In the Fig. 1 embodiment a seismic source 16 and spread of 36 hydrophones (or 36 hydrophone arrays) are towed along a traverse at a constant speed sufficiently slow to minimize towing noises. With the source actuated at a first location the outputs of hydrophones 1 to 24 are recorded on a 24-channel recorder. When the source and spread have moved a distance equal to half the spacing of adjacent hydrophones the source is actuated again, but this time the outputs of hydrophones 2 to 25 are recorded. Further recordings are made with the source at successive locations, using hydrophone groups 3 to 26, 4 to 27... &c. respectively. After twelve source actuations (shots) the towing speed is increased and recordings are discontinued until the source and spread have advanced a further six hydrophone spacings, i.e. through twelve inactive locations of the source. The slow speed is then resumed and the recording procedure is repeated. This results in a full 12-fold coverage of common depth points along a complete traverse, obtained at a higher average speed than if a single towing speed were used. Instead of switching recording channels from one group of 24 hydrophones to another all the hydrophone outputs may be recorded simultaneously and the recordings may then be selected in groups of 24. The common depth point recordings are stacked and enable moveout corrections to be analysed. Alternative embodiments are described for obtaining otherfold coverages of the subsurface by varying the numbers of hydrophones in the spread, of hydrophones in the group, of consecutive source actuations before the recording is discontinued, and of inactive source locations.
