Title: Improvements in resilient connections between sprung and unsprung bodies
IPC: B60G3/20
Filed: 1942-05-14
Abstract: 559,776. Resilient connections ; vehicle suspensions. HORSTMANN, S. A., and HORSTMANN, Ltd. May 14 1942, No. 6565. [Classes 108 (ii) and 108 (iii)] A resilient connection between sprung and unsprung bodies, particularly for use in a vehicle suspension, comprises two super imposed and independentlypivoted levers, one lever, which is controlled by an elastic element, being movable by the other through the intermediary of a roller free to change its position relatively to each lever, in such a manner that the ratio of the amount of movement of the controlled lever to that of the other lever increases as the levers move from normal position. As shown, a lever 2 carrying a road wheel or axle 7 has a curved surface 2a separated by a roller 5 from an oppositely-curved surface la on a lever 1 on the vehicle body, the pivots 4, 3 of the levers being in separate vertical planes. Movement of the lever 1 is controlled by a torque rod constituting the pivot 3 or the lever may be carried on a pivot rigid with the vehicle body and sprung by coil or leaf springs. When the levers are of substantially the same length, the lever 1 moves through a greater angle, and therefore at a greater rate than the lever 2. When the effective lengths differ substantially the rate of movement of lever 1 will always increase at a greater rate than that of lever 2 although lever 1 may not have a greater angular travel than lever 2. The rolling surface of each lever or both levers may be straight, inclined or cam-shaped and the roller 5 may be mounted on a pivoted link or may engage slots formed in plates carried by the lever 1 or may be controlled by other means.

Title: Manufacture of fatty acid aryl hydrazide sulphonic acids
IPC: D01C3/00
Filed: 1945-03-17
Abstract: Fatty acid aryl hydrazide sulphonic acids wherein the fatty acid residue contains at least 10 carbon atoms (see Group IV) may be employed for emulsifying and dissolving lime soaps.  The sulphonic acids may be those derived from stearic acid, copra oil fatty acid, lauric acid and palm kernel oil fatty acid on the one hand and phenyl hydrazine on the other.ALSO:In a modification of the process of the parent Specification, fatty acid aryl hydrazide sulphonic acids wherein the fatty acid residue contains at least 10 carbon atoms are prepared by directly sulphonating admixtures of aryl hydrazines or the N-alkyl or N-hydroxyalkyl derivatives and fatty acids containing at least 10 carbon atoms or their esters, halides or anhydrides, with fuming sulphuric acid or other sulphonating agent.  Thus, molecular quantities of phenyl hydrazine or a salt thereof, and of the fatty acid or of its above-mentioned derivatives, especially of a glyceride, can be dissolved in sulphuric acid monohydrate and sulphonated with fuming sulphuric acid.  In examples: (1) phenyl hydrazine hydrochloride and stearic acid are treated in sulphuric acid with oleum as described above, the product poured on to a mixture of ice and sodium chloride, the sulphonic acid compound filtered off, neutralized with caustic soda and dried yielding a softener; (2) phenyl hydrazine-p-sulphonic acid and copra oil fatty acid are reacted similarly yielding a wool-washing agent and has emulsifying powers (see Group III).  The copra oil fatty acid may be replaced by a glyceride such as palm kernel oil or a halide of lauric acid or copra oil fatty acid.

Title: Device for moving a movable rod back and forth
Inventor: PACCHIONI ANTENORE
IPC: G01T5/06
Filed: 1969-02-10
Abstract: 1,244,107. Fluid operated single stroke device. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb.10, 1969 [Feb.29, 1968] , No.7000/69. Heading F1P. [Also in Divisions F2 and G4-6] A device for causing the movable system of a bubble chamber to perform a forward stroke followed by a return stroke, comprises, a rod 16 connectable to the movable system, a piston 18 urged upwardly by differential gas pressure there-' across, a valve member 32 urged downwardly against a seat 30 by liquid continuously supplied to a chamber 34, and a valve 42 operable to supply liquid to a chamber 36 thereby to lift the valve 32 and equalize the pressure thereacross so that the gas under the piston 18 expands to cause upward movement of the shaft. During the upward movement liquid in a chamber 48 is forced by the end of the shaft 16 into a return line 44 via a chamber 60 and an open valve 62 and also via a channel 56 and an open valve 52. Pressure in the chamber 48, however, does not completely collapse due to the liquid having to flow through throttles 53, 64. The downward stroke commences when the gas pressure in chamber 24 exceeds that in chamber 22. Thereafter the valve 62 is changed over thereby to cause pressurization of the chamber 48 via chamber 60. Because of the throttle 64 pressure in the chamber 60 is higher than in the chamber 48 whereby the valve 52 is lifted to a closed position so that pressure builds up in the chamber 48 to return the rod 16. As the valve 32 approaches its seat 30 the valve 42 is changed back thereby reducing pressure in the chamber 36 so that the valve 32 re-seats. The operation of the valves 42, 62 is controlled by an electrical timing device 78.

Abstract: 196,587. Kohler, C. April 19, 1922, [Convention date]. Cooling condensers, air blast for. - Apparatus for cooling the condenser cooling-water of steam locomotives bv direct contact with air comprises an opentopped chamber 2 mounted on a tender, the water being distributed in fine streams from perforated pipes 4 and passing downwardly through staggered perforations in a series of horizontal plates 8, while the cooling-air, which is forced in by a fan or fans 10, rises through the same perforations in the plates. The perforations in the plates should be at least 5 mm. in diameter and preferably of a cross-sectional area not less than one and a half times the area of the openings in the pipes 4. They may be of different sizes. In order to avoid cross-currents of air the chamber may be divided by vertical partitions 15. The fan delivers the air into a funnel 12 closed at the top but perforated at the sides 13 and open at the end, so as to distribute the air uniformly over the base of the chamber. The air may be delivered through two side passages, and the passages maextend the full length of the chamber. The structure is shaped to the form of the railway clearance gauge. The pipes 4 are connected at the front to a supply pipe 7 and are closed at the opposite end. The air inlets may be at the sides, as shown, or at the front, in which case the motion of the vehicle assists the action of the fan.

Title: Means for converting a direct voltage into a frequency proportional thereto
IPC: H04N5/12
Filed: 1941-06-04
Abstract: 549,614. Relaxation oscillators. TRIGGS, W. W. (Akt.-Ges. Brown, Boveri, & Cie). June 4, 1941, No. 7080. Addition to 548,396. [Class 40 (v)] The condenser relaxation circuit for converting a variable direct voltage into a frequency proportional thereto as described in the parent Specification is modified by using a single valve both to amplify the direct voltage and to amplify the tripping impulse to discharge the condenser through a gas-filled valve. The direct voltage Vx is applied to the grid of the double-function valve 3, so as to vary the rate at which a condenser 2 is charged, from a source 5 through the valve. At the appropriate moment, determined as in the parent case by the elements 6 ... 10, an impulse passes through the transformer 11 to the grid of the valve 3, being excluded from the source Vx by a filter 12, 13. An amplified pulse appearing across the coil 14 in the anode circuit is applied to the grid of the gas-filled valve 1 to discharge the condenser 2. The discharge frequency of the condenser 2 is thus dependent on the variable direct voltage Vx.

Abstract: 1,027,828. Magnetic playback apparatus for educational use. DAWE INSTRUMENTS Ltd. Jan. 13, 1965 [Feb. 20, 1964], No. 7152/64. Heading G5R. Teaching apparatus, e.g. for teaching languages, comprises a film 1 which is movable intermittently to allow successive scenes to be displayed on a screen 6, an associated commentary on the film being detected by a magnetic head 8 and re-recorded on an endless magnetic tape 11 so that it may be played back repeatedly. The motor 2 driving the film 1 is started by means not shown and stopped by a detector 3 which measures off discrete frame lengths. Whilst the film is moving signals from the head 8 are fed to the record head 10 acting on the tape 11 and are played back into a loudspeaker or headphones 13 by means of a head 12. An erase head 14 is energized whilst the motor 2 is running. The tape 11 moves continuously and may move at the same speed as the film 1, the length of the loop 11 being equal to one frame's length on film 1. Alternatively the speed of the loop 11 may be variable to cater for different frame lengths. If the switch 9 is moved to its other position, signals from the head 8 pass direct to the loudspeaker 13, and in this mode of operation the film may be driven continuously.

Abstract: 390,309. Controlling consuming devices. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Assignees of Brown, G. C. ; West Milwaukee, Wisconsin, U.S.A.) March 10, 1932, No. 7189. Convention date, March 13, 1931. [Class 38 (iv).] The current in a gaseous electron tube 6 is not established until a given time after operation of a control switch 17. A condenser 10 in series with the grid 9 is charged while the switch is closed, and upon opening the switch the grid potential falls below that of the cathode, due to the cessation of current in a resistance 13, so that the tube cannot conduct. A continuously rotating commutator 15 then becomes effective gradually to discharge the condenser, through an adjustable resistance 16, in a succession of intermittent periods. The anode circuit of the tube is completed at contacts 18 and when the grid potential has risen sufficiently the tube becomes conducting. The switch 17 may control a load 1, which is energized for the period during which the tube is nonconducting by including in its circuit the contacts of a relay 3 in the anode circuit of the tube. Specification 386,675 is referred to.

A single phase to three phase converter comprises three tank circuits, each having saturable inductors 4, 5, 6 and capacitors 7, 8, 9 in parallel, arranged so that the sum of the fluxes in the three saturable inductors is zero. This is achieved by delta connecting windings on the inductors or by winding the inductors on a common three-legged core. With the arrangement of Fig. 2, in which linear reactors 1, 2, 3 are included, a three-phase output is obtained from terminals a, b, c when a single phase input is applied to any two of the input terminals A, B, C; at starting a three-phase input is briefly applied, by a phase shifting circuit, to determine phase rotation. A singlephase load may be supplied from a threephase supply and the three-phase currents will be balanced. Output voltage in either direction of conversion is stabilized by the saturable inductors and capacitors. The invention may be used in protective relay equipment and for A.C. railways where three-phase traction motors are fed from a single-phase supply.
