Title: Load controlled valve for vehicle air springs
IPC: F16K31/36
Filed: 1958-09-23
Abstract: 838,808. Maintaining vehicle constant height. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Sept. 23, 1958 [Oct. 28, 1957], No. 30387/58. Class 108(2) Air from a reservoir 40 (Fig. 1) passes to a pneumatic suspension spring 12, under the control of a member 46 (Fig. 2) which on rising lifts a valve 30. On lowering of the member 46 from the position shown, air passes from the spring 12 via a chamber 54 and passage 58 to atmosphere. The movement of the member 46 is effected by the rotation of an eccentrically mounted cam 66 when the latter is in the position shown in broken lines. Rotation of the cam 66 follows deflection of a lever 18 connected to the axle 16. Axial movement of the cam 66 is permitted by a spline connection 84. On application of pneumatic pressure to a space 86 under control of a valve 88, the cam 66 is projected against the action of a spring 70 from the position shown, to the broken-line position.

Title: Improvements in or relating to thermionic valve circuits of the kind for supplying electric current pulses having constant peak amplitude
IPC: H03K3/78
Filed: 1953-11-04
Abstract: 753,662. Pulse amplitude limiting circuits. GENERAL ELECTRIC CO., Ltd. Oct. 29, 1954 [Nov. 4, 1953], No. 30540/53. Class 40 (6). The amplitude of current pulses is maintained constant, by feeding a train of positive-going pulses to the grid of a discharge tube 15 with a cathode resistor 17 returned to a negative point, the cathode potential being maintained between pulses at a level determined by a by-pass circuit comprising a diode 29, resistor 31 and capacitor 32. The incoming train is D.C. restored by diode 26 and resistor 27 so that the grid assumes a negative potential with respect to earth except during the pulses when it rises to earth potential. The amplitude of the current pulses may be altered by varying resistor 17 and they may be employed to shockexcite a tuned circuit 1 to produce a damped sine wave. Alternate half-cycles are passed by diodes 12, 13 and the resulting pulses may be used in a pulse code modulation system as described in Specification 664,401, each pulse decreasing to half the amplitude of the preceding pulse.

Title: Improvements in and relating to fountain pens
IPC: B43K7/12
Filed: 1957-09-30
Abstract: 875,820. Reservoir pens. KREUTZER,R., and WESSMULLER, - G., [trading as STAEDTLER, J. S. [Firm of]]. Sept. 30, 1957 [Sept, 29, 1956], No. 30579/57. Class 146(3). In a fountain pen; e.g. a ballpoint pen, having a writing unit resiliently supported in the writ-, ing position a helical spring at one end is clamped around and bears against an abutment on a guiding sleeve for the writing unit and at the other end is clamped around and bears against an annular corrugation in a further sleeve which grips the writing unit in a releasable manner. The rear end of the writing unit b is slidable in the guiding sleeve d in the rear end of which is inserted a pushbutton e. A helical spring i is clamped on the front end of the guiding sleeve with its rearmost convolutions and abuts against an annular corrugation k on the sleeve. At its other end the spring i is clamped on the rear portion of a sleeve l and abuts against an annular corrugation m therein. The front portion of the sleeve l is of reduced diameter and slit as at n to produce springy portions which grip the unit b and abut against a collar p formed thereon. Thus the writing unit is resiliently supported in the guiding sleeve d when the latter is displaced axially by actuation of the push-button e and the writing point is thereby projected from the barrel. The barrel a is in two parts and when these are separated the writing unit b can be withdrawn forwardly from the sleeve l and a new unit inserted. A member 1 is secured to the barrel and has claws 3 at its front end which claws engage a projection 4 integral with the sleeve d in the retracted position of the writing unit b. A short sleeve 5 is slidably mounted on the sleeve d and is frictionally held by a projection 7 on the member 1 while the guiding sleeve d is pushed forwards by means of the push-button e until a corrugation 8 engages it. Claws 3 engage behind a projection 10 on the sleeve d and thereby latch the unit b in writing position. A further depression of the push button e causes the sleeve 5 to force the claws 3 apart whereby when pressure on the pushbutton is released the claws will ride over the projection 10 as the sleeve d and unit b are carried back to retracted position by a retracting spring.

Title: Keyboard-operated business machines,such as typewriters
IPC: B41J5/26
Filed: 1961-08-28
Abstract: 975,519. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 28, 1961 [Aug. 26, 1960], No. 30959/61. Heading B6F. Keys; preventing accidental typing.- Operation of a key with too low a velocity or acceleration, due to accidental touch or other causes, delays typing. As shown in Fig. 2, the key 34 is connected to a piston 42 working against a spring 48 in cylinder 35 mounted on key bar 2. The base of the cylinder has a restricted air outlet 46, 56, which can be adjusted, and a valved air inlet 52. Fast depression of the key depresses the bar 2 to operate the typing mechanism as the trapped air in the cylinder cannot escape through outlet 46, 56 quickly. Slow depression causes the air to escape at a comparable rate so that spring 48 is compressed until the piston abuts stop 43 whereupon the key bar is moved. As shown in Figs. 8 and 9, an auxiliary key bar 62 is slidably pivoted at 78 adjacent its abutment with key bar 2 and is pivoted at 66 to a lever 64 pivoted at 68 and formed with a heavy end weight 74 working between stops 70, 72. At low accelerations of key 34, Fig. 8, weight 74 is lifted until it abuts stop 72 and thereafter the slotted end of bar 62 moves down to actuate the key bar 2. At high accelerations, Fig. 9, the inertia of weight 74 prevents it rising and the end of bar 62 descends at once to actuate key bar 2.

Title: Improvements relating to s-thiuronium alkanesulphonates and the preparation thereof
IPC: C07C335/32
Filed: 1952-12-08
Abstract: The invention comprises S-thiuronium alkane sulphonates having the general formula <FORM:0735070/IV (b)/1> where n is a number from 1 to 5 which are prepared by reacting thiourea with a haloalkane sulphonate X-(CH2)nSO3M1, where n is as defined above, X is a halogen, preferably chlorine or bromine, and M is a metal which forms a water-soluble sulphite.  Generally, the reactants are used in equimolar proportions in an inert reaction medium at elevated temperatures up to the boiling point of the medium.  The halo-alkanesulphonates are prepared by reacting a dihalo alkane X(CH2)nX with a stoichiometric amount of a sulphite of the metal M, e.g. an alkali metal or ammonium sulphite or a meta-bisulphite of the metal in conjunction with a molar proportion of the hydroxide of the metal.  In examples: (1) ethylene dibromide and sodium sulphite are heated under reflux in aqueous ethanol and the resulting mixture is worked up to recover sodium beta-bromoethane sulphonate mixed with sodium bromide which are reacted with aqueous thiourea yielding beta-S-thiouronium ethane sulphonate; (2) as in (1), the bromo ethane sulphonate mixture being obtained as a liquid concentrate for reaction with thiourea; (3) as in 2 using, however, ethylene dichloride and potassium sulphite as starting materials.

Title: Improvements in pulse generators
IPC: H03K3/281
Filed: 1965-07-21
Abstract: 1,114,745. Multivibrators. GEBRUDER SCHMIDT METALLWARENFABRIK. 21 July, 1965 [25 July, 1964], No. 31045/65. Heading H3T. [Also in Division G3] A battery-operated multivibrator has the pulse repetition rate made independent of changes in the internal resistance of the battery by arranging that a capacitor is charged by the battery through a load in one half-cycle and then charges a further capacitor during the other half-cycle. In Fig. 2 capacitor C2 is charged by the battery through diode D and acts as voltage source for the frequencydetermining capacitor C1. When the transistors conduct, C2 discharges through T2, NTC, R2, C1 and the base-emitter path of T1 to charge up C1 If the mark-to-space ratio is very large, e.g. with one pulse per minute, the diode may be replaced by a high resistance. Relay contacts may also be used instead of a diode. The load may be a relay Ra driving a clock or perpetual calendar. Resistor R4 controls the interval between the pulses.

Title: Improvements in automatic or semi-automatic telephone systems
IPC: H04M17/02
Filed: 1948-12-02
Abstract: 651,693. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., BONHOMME, V. G., and WARDLE, A. Dec. 2, 1948, No. 31193. [Class 40 (iv)] At a prepayment station in which the insertion of a coin makes the dial effective, the insertion of an additional coin sends a ground impulse to the exchange to allow the group selector access to junctions leading outside the single-fee area. The operation of the balance arm contacts BA by a coin removes a shunt from the impulse springs IM, relay A and magnet B. Relay A energizes at this time and magnet B energizes upon the reversal of current when the called party replies to drop the coin. Dial contacts .0 enable 0 level calls to be made free. The insertion of a second coin operates flip contacts FC momentarily, with the result that relay C energizes and falls back slowly, sending a ground impulse to the exchange. The group selector is of the kind in which test relay H is operated before rotary stepping starts and is held over the test wiper as long as busy outlets are encountered. A differential relay DF in series with line relay A is provided to respond to the ground impulse mentioned above. If the selector is set to a level leading to a multi-fee area, post springs NP1, 2 are operated, and if DF is not energized relay H is held permanently until the end of the level is reached, when NU tone is returned. With DF up, however, the effect of the post springs is nullified and the call proceeds in the normal way. The arrangement may be extended by making DF control a chain of relays which permit access to various levels leading to higher fee areas as additional coins are inserted by the subscriber.
