Filed: 1971-07-21
Abstract: 1394828 Shearing; punching; bending GLACIER METAL CO Ltd 21 July 1972 [21 July 1971] 34089/71 Headings B3W and B3E [Also in Division F2] A half bearing is made by feeding a strip lengthwise into a press step by step, operating the press after each step to perform an operation on each of a plurality of different blanks constituting successive transverse lengths of the strip, one operation of the press constituting a movement of a die to partially sever a partformed bearing blank from the strip and a further operation constituting a movement of the die to completely sever the blank from the strip and to form the severed blank into a part cylindrical shape. The strip 11 is fed into the press which comprises a movable top bolster 13, an intermediate bolster 24 which is carried by springs 25 on a bottom bolster 26. The bolsters carry tools which form the bearing. The strip is first chamfered and embossed by tools 27 and 28 and an anvil 29, and is then advanced and sheared across its width by angled blades 31, 32 except for a small central portion 17. The strip is again advanced and is engaged by a coining die 33 which severs the blank from the strip and forces the blank over coining blocks 38 to cause the blank to assume a semi-cylindrical shape. As the top bolster rises, a spring 39 below the coining block pushes the block and blank upwardly and as the strip is advanced the blank is pushed on to the next station in the press where it is tagged and punched by tools 46, 47 to form a lubricant orifice. The formed bearing is then ejected from the press. (For Figure 1 see next page.)

Title: Improvements in and relating to electric circuit controllers
IPC: H01H9/26
Filed: 1936-12-11
Abstract: 488,658. Actuating controllers; partly electromagnetic switches; preventing sparking; field control of D.C. motors. BRITISH THOMSON - HOUSTON CO., Ltd. Dec. 11, 1936, No. 34090. Convention date, Dec. 11, 1935. [Classes 38 (iii) and 38 (v)] Each of a number of switches 10-14 is arranged to be moved initially to its closed position by resilient means and closed with a snap action by an electromagnet as described in Specification 450,911, and to ensure operation of the switches in correct sequence, interlocking means are provided which prevent operation of a second switch until a first switch has opened. Upon operation of a handle 16, a spring 35 is stressed to operate a switch 11 to its closed position and connect a vehicle motor to its supply, and by further operation of the handle, switches 14 and 13 are closed in sequence to cut out sections of series resistance, the further movement of the handle also biassing switches 12 and 10 to their closed position. The switch 10 is prevented from closing by the engagement of an arm 69 with a pivoted interlocking bar 74 which is rotated into a stopping position when the switch 11 closes. The switch 12 closes at the fourth position of the handle and effects reduction of the energization of the electromagnetic coil 21 of the switch 11 so that the force exerted by the stressed spring 73 of the switch 10 operates through the bar 74 to open the switch 11 and close the switch 10. This operation of the switches 10, 11, 12 changes the connection of sections of the motor field from series to parallel. A similar interlocked actuation of the switches 10, 11, 12, whereby the switch 11 is reclosed and the switches 10, 12 reopened is effected by reverse movement of the handle.

Title: Improvements in or relating to gas turbine plant
Inventor: CLARK NEIL MILLIGAN
IPC: F02C6/18
Filed: 1959-10-08
Abstract: 884,789. Gas turbine plants. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Oct. 7, 1960 [Oct. 8, 1959], No. 34177/59. Class 110 (3). A gas turbine plant comprises compressor means the output of which is divided into two streams, one stream passing to a first heatstoring element in which it is heated, combustion means to receive the other stream, turbine means fed by the combustion chamber, a second heat-storing element to receive at least a part of the exhaust from the turbine means, valve means for intermittently interchanging the flow of the two streams through the heat-storing elements and heat exchange means to receive heat from the exhaust gases from one of the heat storing elements and to heat the whole output from the compressor means. An axial flow compressor 1 discharges through a heat exchanger 5 to an air turbine 7. The exhaust of the air turbine 7 is divided into two branches, one branch 9 leading to a first heat-storing element in the form of a Cowper stove 10 and the other branch communicating with a combustion chamber 12. Fuel for the combustion chamber is blast furnace gas supplied by a gas compressor 14 discharging through a heat exchanger 16. In practice, the compressor 14 is on the same shaft as the air compressor 1 and air turbine 7. The combustion chamber 12 feeds a gas turbine 17 which discharges through a twoway valve 20 to a second heat-storing element in the form of a Cowper stove 24. The combustion chamber of the Cowper stove receives blast furnace gas from the compressor 14. An exhaust duct 33 from the Cowper stove 24 leads to a second two-way valve 26 and to the hot pass of the heat exchanger 16. The valve 20 is connected to the valve 26 through duct 25. Duplicate ducts lead to each Cowper stove to permit intermittent interchange of the gas flows. The valves 20, 26 allow a supply of exhaust gases to the heat exchanger 5 whilst the interchange of the flows between the two Cowper stoves takes place. In a modification, Fig. 2 (not shown), the output of the compressor 1 is divided upstream of the turbine 7. In a further modification, Fig. 3 (not shown), the valves 20, 26 are omitted and the exhaust gases drawn through the Cowper stove 24 by an induced-draught fan which may have variablespeed drive. The air turbine 7 may be omitted. The valves 20, 26 may be used to divert a variable portion of the exhaust gases to the Cowper stove that is being reheated.

IPC: A24C5/31
Filed: 1967-07-26
Abstract: 1,137,308. Cigarette-making machines. TABAK-UND INDUSTRIEMASCHINEN DRESDEN, VEB. 26 July, 1967, No. 34259/67. Heading A2C. In the operation of a continuous rod cigarette-making machine of the type in which cut tobacco is fed from a distributer roller to form a rod on a suction conveyer wheel, when stopping the rod forming process first the drive to the distributer roller is disengaged by an electromagnetically actuated clutch while simultaneously an electromagnetically actuated brake is applied to the roller and then after a timed delay by a delay relay the drive to the suction conveyer wheels is disengaged by a second electromagnetically actuated clutch. The machine is stopped in this manner to ensure the formation of as uniform a rod as possible when subsequently restarting the machine.

Title: A system for effecting automatic control of a vehicle power transmission system
Inventor: MAY CLIFFORD FRANK
IPC: B60L3/00
Filed: 1954-11-27
Abstract: 780,666. Controlling change-speed gearing. LUCAS (INDUSTRIES), Ltd., J. Nov. 16, 1955 [Nov. 27, 1954; Feb. 14, 1955], Nos. 34438/54 and 4275/55. Class 80 (2). In a motor vehicle, automatic control of top gear (overdrive or direct drive) is effected by an electric generator a, driven by the engine or by the vehicle, whose voltage varies with speed and which is connected, through a rectifier b where necessary, to a relay winding c in series with a variable resistance d controlled by the accelerator or by engine suction so as to be increased with increased throttle opening, a normally-open switch h adapted to be closed by the relay c, a normally closed switch g adapted to be opened by kick-down of the accelerator, and a gear-changing electromagnet i adapted to be energized from a separate source under the control of a switch s operated by the relay c,'the switches g, h being arranged in series so that, when both are closed, they short-circuit at least the major part of the resistance d. Below a certain speed, dependent on the amount of the resistance d in series with the winding c and hence on the throttle opening, the current in the winding c is insufficient to operate the switch s and the magnet i remains deenergized. Above that speed, switch s is operated to energize magnet i, so as to bring top gear into operation, and switch h is closed, so as to hold top gear until the speed falls sufficiently to render the relay c ineffective or until kickdown of the accelerator. The resistance d may be varied by a sliding contact, or, as shown, by normally-closed short-circuiting switches f<SP>1</SP>, f<SP>2</SP> ... adapted to be opened'successively as throttle opening increases. Switch s may be a normally-open switch in series with the magnet i. As shown, however, it is a two-way switch and the magnet i is associated with a normallyopen switch m adapted to be closed by an electromagnet n and with a normally-closed switch p adapted to be opened when the throttle is closed. Normally-closed switches q, rare operable at will or during reverse drive to render the magnet i inoperative. With switch s positioned as shown, magnet n is shortcircuited and magnet i de-energized. When switch s is moved to its other position by the relay c, magnet n is energized to close the switch m, and thus energize magnet i. A signal lamp t is arranged in parallel with magnet i. Instead of being operated by winding c, switch h may be actuated by magnet n or by magnet i.

Abstract: 918,371. Phase synchronizing devices for secret telegraphy. GRETAG A.G. Sept. 26, 1961 [Sept. 30, 1960], No. 34502/61. Class 40 (3). In a secret telegraphic system of the type in which extra pulses are interleaved in the data pulse train at the transmitter and deleted from the pulse train at the receiver, the insertion and deletion of extra pulses being controlled, for example, by identical punched tapes at the transmitter and receiver which tapes have to be read synchronously at the transmitter and receiver, means are provided to ensure that reading of the two tapes commences simultaneously at the transmitter and receiver, subsequent synchronization being effected by known means not described. At the transmitter 24, Fig. 1, immediately prior to commencing tape reading stepping of a cam 40 by a pawl-and-ratchet mechanism 32, 36 is started and at the same time an attempt is made, by transmitting a signal over a radio link to a receiver 26, to initiate simultaneously the stepping of a similar cam 40 at the receiver. However, owing to noise or fade-out the cam 40 at the receiver may start either before or after the cam 40 at the transmitter and the device described functions to bring these two cams into phase so that at the end of one revolution they can both actuate devices 52 to initiate simultaneously the tape reading. As the cam 40 at the transmitter rotates it causes devices 44, 46, 48, 50 to generate a sequence of characters, e.g. A, B, C, D, which are transmitted to the receiver where they are compared, in a comparator 56, with a similar locally-generated sequence. If the two sequences received by the comparator 56 are in phase agreement, e.g. if the two A's are received simultaneously, then the cams 40 are in phase and no action is required. If, however, the two character sequences are not in phase, e.g. if an A is received with a B then the comparator suitably controls a differential gear 54 so as to bring the two cams into phase. The actual comparison can be done by relays and the correction effected automatically or the two character sequences can be used to control a teleprinter so arranged that printing only occurs when the characters are not in phase and any correction can be effected manually.

Abstract: 846,712. Feeding webs. MASCHINENFABRIK BENNINGER A. G. Nov. 14, 1956 [Nov. 21, 1955], No. 34845/56. Class 100(1) In an apparatus for feeding a textile web in which the web is looped successively over a plurality of rollers some at least of these rollers are driven independently of the other rollers by driving means having a flat speedtorque characteristic, the power transmitted to these rollers being just sufficient to overcome the frictional resistance of the rollers, while the web is fed through the apparatus by separate feeding means. As shown, a textile web 1 is fed by rollers 6 to a tank 5 containing treating liquid and rollers 2 some of which are driven through chains 4 by electric motors 3. The electric motors have flat speed-torque characteristics, e.g. they may be squirrel cage motors, motors having short-circuited armatures, or single-phase motors with screened holes. The motors 3 have outputs just sufficient to overcome the frictional resistance offered by the rollers 2. A motor 7 drives a roller at the delivery end of the tank 5 at a slightly higher speed than the rollers 6. If another apparatus follows the tank 5, the roller 7 may be dispensed with. A spring-pressed detector roller 8 operates a switch 9, upon breakage of the web, to stop the motors 3 and 7. The rollers 6 may be replaced by an adjustable brake, not shown, so as to produce variations in web tension.
