Title: Tracked vehicle and a steering control
IPC: B62D11/18
Filed: 1975-04-24
Abstract: 1498883 Hydrostatic transmission control; link work DEERE & CO 24 April 1975 [26 April 1974 1 May 1974] 16960/75 Headings F2W and F2K In a steering linkage controlling separate hydrostatic transmissions driving tracks on opposite sides of a vehicle and having pedals 44, 68 acting through linkages 40, 66 on steering control valve levers 30, 32, "feel" is provided in each linkage by a spring 60 that progressively resists movement of the associzated pedal 44 whilst the latter is reducing the output speed of the associated transmission to zero and a further spring 54 which provides an additional progressive resistance to movement of the assocciated pedal 44 when the latter reverses the associated transmission. The spring 60 acts between a fixed abutment 42 and a ring 58 fast with a rod 40 of the linkage whilst the spring 54 acts between a ring 52 which axially slidable on the rod 40 and an abutment ring 48 secured to the rod 40. During initial movement of the rod 40 the ring 52 is held against the abutment ring 58 and the spring 60 provides the "feel". When the transmission output speed is zero the ring 52 abuts a tube 46 fast with the fixed abutment 42 and thereafter further movement of the rod 40 is resisted by the combined action of the springs 54, 60. An interlock 84 prevents simultaneous movement of both pedals 44, 68 beyond their positions corresponding to zero output speed of their associated transmissions. Pins 94, 96 engage grooves 98, 100 in the pedals 44, 68 to limit movement of the pedals. An additional manual control acts through a linkage 28 (see Specification 1,498,882) on a control valve lever 118 which effects equal speed and direction changes in both transmissions. In Fig. 7 (not shown) the control pedals 44, 68 are replaced by hand levers.

Title: A new or improved time alarm for scaring burglars
IPC: G04C21/00
Filed: 1927-06-27
Abstract: 296,841. Pocock, Sir S. J., and Pocock, M. S. June 27, 1927. Time alarms.-Comprises a construction suitable for scaring burglars in which audible and/or visible signals are given electrically in a cycle of intermittent impulses repeated as long as the timepiece is going. A box 1 contains a timepiece the dial 2 of which can be seen through the front. The casing houses a lamp or bell or both, an aperture being left for the beam or the lamp 3 may be on top as shown. The bell 4 is mounted in the wall or outside the box, which also houses batteries 5. An arm 6 mounted on but insulated from the clock spindle travels over contact studs 7 on the back of the dial. The circuit is from battery 5 to the bell and lamp in parallel to the axle 10 while the axle is connected through the switch arm 6 and contacts back to the battery. In modification a fixed contact is adapted to engage a set of contact blades spaced around a toothed wheel keyed on the spindle 10. The angle of each contact blade determines the duration of the signal. In a further form two sets of contacts are arranged one on each side of the wheel to contact with a separate switch arm whereby the visible and audible signals are given at different intervals. Cut-out switches to render the signals inoperative may be fitted. The direction of the beam may be changed by pivoting the lamp by means of a universal joint and connecting to a cam driven by the clock or another clock mechanism.

IPC: H03K19/16
Filed: 1957-05-29
Abstract: 841,587. Circuits employing bi-stable magnetic elements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 24, 1958 [May 29, 1957], No. 17037/57. Class 40 (9). Bi-stable cores 1, 2 are normally reset by a pulse in windings d to states (0) and (1) and are changed to states (1), (0) only when a reference pulse in winding a is not accompanied by a signal pulse in winding b. Coincident pulses cancel and have no effect. Thus, if pulse intervals identified by reference and signal pulses are denoted by A and B, the cores 1, 2 respond only in intervals A(1 - B). After a sequence of pulses, the condition of core 2 is read by applying a pulse to terminals c. If core 2 is in its normal state (1) indicating that all reference pulses have been accompanied by signal pulses the winding presents a high impedance to the pulse, the currents in half-windings w1, w2 on core 3 are unbalanced and a signal is transmitted by winding e as core 3 is switched. If core 2 has been changed to state (0) to indicate a missing pulse, the balanced currents in windings w1, w2 give no signal in winding e. The read pulse is followed by a reset pulse in winding d. If the windings to which the signal and reference pulses are applied are interchanged the device responds in intervals (1-A)B. Coincidences of whole sequencies of reference and signed pulses may be indicated by an AND element controlled by the two alternative arrangements described. This device responds if all the pulse intervals of the sequence are AB intervals.

Title: Tape recorders
IPC: G11B15/24
Filed: 1975-04-24
Abstract: 1506625 Recording tape transports LICENTIA PATENT VERWALTUNGS GmbH 24 April 1975 [24 April 1974 4 March 1975] 17068/75 Heading G5R A tape transport incorporates a device for stopping a drive motor and/or for altering the torque transmitted by a slipping clutch to a tape take-up element when the take-up element slows down or stops. In a device for stopping the drive to the takeup element 28 should the latter stop or run too slow, e.g. due to tape jamming in a cassette, the slipping clutch is formed by a felt ring 29, Fig. 3, between element 28 and a drive element 36 driven by roller 30 of motor 34. An epicyclic gear assembly has a planet wheel 8 located on a carrier 9 and engaging a gear 2, driven from element 36 via gear 32, 33, and engaging a gear 12 driven by a gear 16 on element 28. During normal operation carrier 9 rotates around shaft 1 of gear 2 in one direction, but rotates in the opposite direction if element 28 stops or slows down too much and thereby causes, e.g. by ratchet teeth (17), (18), Fig. 2 (not shown), movement of a slider 20 to open or switch to stop motor 34. In a device for increasing the torque transmitted by the slipping clutch if the take-up element slows down too much, whereby constant tape tension and even winding may be maintained, the drive motor rotates drive element 36, Fig. 4, driving take-up element 28 via clutch 29, and a gearing assembly 51, which may be similar to the epicyclic assembly in Fig. 3, has a planet gear coupled to two gears driven by elements 28, 36, respectively so that a part 54 of a further clutch 54, 55 rotates with the planet gear carrier. During normal operation clutch part 54 rotates in direction 53 thereby driving, via teeth 61, 62, part 55 of the further clutch in direction 56. At a predetermined speed of element 28, part 54 rotates in direction' 52 whereby, because part 55 is prevented from rotating in direction 52 by a free-wheel arrangement 57, part 54 displaces part 55 axially to compress spring 59 thereby increasing the torque transmitted by clutch 29 and speeding up takeup element 28. Should parts 54, 55 become relatively displaced by such an extent that, due to the shape of teeth 61, 62, part 55 jumps back axially to its normal position, such jumping back may be used to de-energize the drive motor. Alternative gearing arrangements coupling the two sides of the clutch together and sensing the relative speeds thereof are described with reference to Figs. 2, 5 and 6 (not shown). The devices are interconnected with a pause control so that operation of the latter does not cause the device to effect drive disconnection and/or increased torque of the slipping clutch. Two devices associated respectively with tape supply and take-up reels enable automatic drive disconnection in the above manner during fast forward wind and rewind, recording and playback.

Abstract: 736,379. Control of motors; controllers. CHANCE BROS., Ltd. June 15, 1954 [June 22, 1953], No. 17186/53. Class 38 (3). A squirrel cage motor is started by closing a push-button switch st to energize relay-coil m/4 and close contacts m1, m2, m3 and m4. A manually rotatable switch is in a position to close contacts s1, s2, so that the motor is started with its windings connected in star. Before the rotatable switch can perform its next operation, contact rl of a delayed-action relay r/1 must move to its alternative position. With actuation of the latter switch, contacts s6, s9 are simultaneously opened, the contacts s1, s2, s7 being subsequently opened together. The contacts s3, s4, s5 and s8 are afterwards closed so that the motor windings are connected in delta. Finally, the contact s9 is reclosed and the push-button st is released. To stop the motor, the push-button switch sp is opened, and, if the motor windings are left connected in delta, actuation of the push-button st does not re-start the motor since the contacts s6 will be open. In other arrangements, there are more than two starting-stages, and the motor is of the direct-current type. The delayed-action relay may be of the electromagnetically-operated or thermally-operated types.
Patent GB-495889-A (GB)
Title: Improvements in the manufacture and production of liquid hydrocarbons from gases containing olefines
IPC: B01J19/00
Filed: 1937-06-21
Abstract: Liquid hydrocarbons are produced from gases containing methane homologues and olefines by substantially completely separating the olefines, subjecting the remainder to cracking or dehydrogenation, mixing with the separated olefines, and polymerizing the mixture at above 350 DEG  C. and under superatmospheric pressure, usually above 20 atmos.  The olefines may be separated by oil washing, passage over active carbon, partial liquefaction, or ammoniacal copper solutions. Cracking or dehydrogenation of the paraffins can be effected at 300-900 DEG  C. in tubular furnaces or Cowper apparatus with, if desired, addition of catalysts and oxygen or steam.  Both this reaction and the final polymerization may be performed in vessels lined with silicon or of high chromium steels as described in Specifications 368,291, 403,647, and 469,101. Polymerization of the final mixture is preferably effected at 400-600 DEG  C. and 50-300 atmos.  Diolefines and acetylenes may first be removed as by a mild hydrogenation according to the process described in Specification 359,421.  In an example, a gas containing 32 per cent olefines and 68 per cent methane homologues is treated with ammoniacal copper solution to remove olefines, the paraffins are partially converted to olefines at 800 DEG  C., mixed with the olefines set free from the copper solution, and led into a silicon lined tube at 530 DEG  C. and 120 atmos.  The product may be hydrogenated or mixed with anti-knock agents, and is used as a fuel or blending-agent.

Title: Improvements in multi-channel carrier frequency transmission systems with echo suppressors
IPC: G07D9/04
Filed: 1935-06-18
Abstract: 458,419. Multiplex transmission. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. June 18, 1935, No. 17546. Convention date, June 18, 1934. [Class 40 (iv)] [See also Group XL] In a multiplex carrier system using common amplifiers for the different channels, echo-suppression is effectec by acting on the modulators. For example the modu lator may be blocked by interrupting or short-circuiting the path over which it receives the carrier current or by the application to the modulator itself of a biassing voltage which makes it inefficient. The invention is described with reference to single-tube and to push-pull carrier-suppression thermionic modulators and to modulators comprising pairs or groups of copper-oxide rectifiers. As shown in Fig. 7, high frequency currents are applied to diagonal points of a bridge of rectifiers 1 .. 4 over transformer AU2 and speech currents are applied from N to the bridge via centre taps on the transformer AU2 and on the output transformer AU1 which passes the modulated carrier currents to the line T+N. The condition of the modulator is governed by a biassing voltage from circuit VG. Fig. 2 shows a circuit for interrupting the supply of carrier current to the modulator connected to U4 without altering the load on the generator, connected to U3, under control of a voltage applied at VG.
