Title: Improved means for separating and feeding sheets to printing machines
IPC: B65H3/06
Filed: 1935-10-11
Abstract: 464,042. Feeding sheets. POLLARD, W. E., and RONEO, Ltd. Oct. 11, 1935, No. 28033. [Class 100 (i)] Sheets are separated from a pile 6 and advanced to feed rollers 4 which feed the sheets to a printing- machine by means of a buckling separator acting on the rear edge of the pile which is registered against a rear stop plate 39. The separating mechanism is mounted in a cross frame 3 which is adjustable longitudinally of a main frame 1 for dealing with sheets of various lengths, and the separators are actuated by cams on a shaft 9 driven by worm gearing splined to a shaft 2 driven by the printing-machine. A separating-roller 10 is mounted in a sub frame 21 which is carried by links 22, 23, oscillated by a cam 14 on the shaft 9. The links cause the roller 10 to move to the dotted line position 25 and buckle the sheet in conjunction with a roller 11 which is moved longitudinally to feed the buckled sheet into the grip of the rollers 4 after the sheet below the top one has been acted upon by a presser member 12 which is depressed by a spring 35 when permitted by a cam 37 acting to raise the presser for the buckling operation. The members 10, 11 are carried by longitudinal slideways 16 suspended by parallel links 17, 18 which are operated by a cam 19 to cause the member 10, 11 to be raised from the sheet while it is being drawn off by the rollers 4.

Title: Improvements in or relating to pressure casting machines
IPC: B29C45/80
Filed: 1947-10-20
Abstract: 631,641. Injection-moulding machines. LESTER ENGINEERING CO. Oct. 20, 1947, No. 28047. Convention date, Dec. 13, 1943. [Class 87 (ii)] [Also in Group XXIII] The die-blocks 4, 5 of a pressure casting machine are so arranged that slight relative movement causes a variation in the pressure applied to the material in the die-cavity, e.g. by actuating an electric switch. Mounted on a stationary die 4 is an adjustable device 14 having a lever 29, Fig. 3, pulled by a spring 31 so that its short arm engages the long arm of a lever 25 of which the short arm engages a slide 23 which engages the movable mould part 5 when the mould is closed. The lever 29 is so connected to a micro switch 15 that when the mould is closed the switch is open and the valves 59 and 60, Fig. 4, are in the position shown so that the fluid pressure supplied by the pump 43 to the cylinder 11 which actuates the injection plunger 12 is kept at a value determined by a pre-set relief valve 53. If however the pressure in the mould causes its parts to begin to separate, the switch 15 is closed causing a solenoid 41 to move the valve 59 to the right which causes the valve 60 to move to the left and connect the pump to exhaust 54 thus stopping injection. If the mould-closing means 7, 8, Fig. 1, should move the parts 4, 5 into close contact again, the switch 15 will open and injection pressure be again applied.

Filed: 1927-10-21
Abstract: 279,838. Otto, W. Oct. 26, 1926, [Convention date]. Addition to 278,757. Cut-out arrangements. -In a safety cut-out arrangement for R÷ntgenray systems, of the kind set forth in the parent Specification, the safety switch e is shunted by a variable resistance f, so that the current intensity in the R÷ntgen tube at which interruption occurs is regulable. The resistance may be varied automatically by association with means for varying the current or voltage in the primary circuit of the tube transformer. In one form, the movable contact r of the resistance is fast with the movable contact v of a variable resistance h included in the primary circuit of the tube transformer b, so that the sensitivity of the switch e may be automatically varied in accordance with the current through the tube. The resistance h is cut out for radioscopie purposes. In another form, the contact r is mounted on a rearward extension of the contact lever i of the auto-transformer g through which the primary circuit of the transformer b is fed from the mains n, so that the sensitivity of the switch e may increase with the voltage supplied by the transformer g.

Title: Improvements in or relating to apparatus for automatically starting, connecting to a load circuit, and stopping a generator driven by a prime mover
Inventor: ZIEMER WILLI
IPC: H02P9/08
Filed: 1956-09-13
Abstract: 840,928. Starting prime movers; self-contained generating systems. SIEMENS-SCHUCKERTWERKE A.G. Sept. 13, 1956, No. 28065/56. Class 38 (4). A self-contained electric generating system is arranged to start and stop automatically in response to the opening and closing of load circuits 4-7. A supervisory relay U connected in series with an auxiliary source 3 is operated by load switches 8-11 causing a stepping mechanism WR to operate starter motor relay AS successively until the engine fires. Relay AS is then disconnected by the voltage measuring relay VS and mechanism WR is stepped to position 35. If the engine has not started when WR reaches position 33, the circuit is locked out by relay SP, until switch DSp is opened manually. Generator G is connected to the load by contactor GS and gs1, operated by voltage relay VS, contacts vs2 disconnecting relay U from the lines R, Y, B. Holding relay SR, connected to current transformers SW through rectifiers G11, G12 and voltage limiter G13, is released when the load current ceases, operating relay AB and hence fuel valve solenoid AN. As the generator slows down relay VS and hence contactor GS are released disconnecting the generator from, and reconnecting the relay U to the lines R, Y, B. Mechanism WR is then stepped through another cycle releasing relay UR by shunting the coil on position 33 and hence the fuel valve solenoid is de-energized. The fuel valve may consist of a magnetically conductive section of the fuel pipe centrally disposed in a solenoid, containing a magnetically conductive member such as a ball engaging with a seating to cut-off the fuel when the solenoid is energized. The circuit may be modified for use on D.C., single phase and 3-phase, 3-wire systems.

Title: Transport system
IPC: F16C29/04
Filed: 1973-06-13
Abstract: 1430001 Tunnel systems; wheel arrangements A G HELM 13 June 1973 28163/73 Heading B7L A rail vehicle 1 running along a track formed by one or more guide rails 3, particularly at high speeds in a tunnel 2, has wheels 4 which are supported in movable members 7 arranged to alternately bring each wheel into contact with the track and remove it from such contact continuously throughout movement of the vehicle. As shown, the wheel-carrying members 7 are mounted on axles 5 extending in the direction of vehicle travel, and rotary motion of the members about the axles effects the intermittent wheel contact. The rails 3 each have a concave contact surface provided with an intermittent helical rib 6 to give a natural tendency for rotation of each member about its axle, although additional drive means may be used for causing such rotation. Alternatively, the intermittent wheel contact may be effected reciprocally by eccentrics, cams or cranks. The invention is intended to alleviate frictional heating problems at the wheel contact surfaces.

Grant of Patent opposed. [Class 61 (iii).] The inner races of two axially spaced ball, or taper, spherically seated or cylindrical roller bearings are internally tapered to engage oppositely directed tapers on an axially split securing sleeve 14 which carries on a threaded cylindrical part between the races, a withdrawal nut 20 adapted to be screwed in either direction for the purpose of removing the races. As shown applied to an axle-box, taperrollers 3, 4 are arranged with their large ends adjacent and their inner races 10, 11 are separately positioned by an end-nut 16 which has locking means. This nut first positions the inside race 10 by engaging the overhanging end of the sleeve 14 before the race 11 has been mounted. The nut is then removed to permit mounting of the race 11 which is then positioned by engagement of its overhanging end with the nut. For the purpose of rotating the withdrawal nut 20 the axle-box may be split and a spanner provided, but as shown this is done by inserting radially through casing apertures 22, pins which engage notches 21 in the nut and prevent its relative rotation whilst the axlebox, or axle is rotated. The pins are shouldered and are held down by surrounding sleeves screwing into the apertures which are sealed by screw plugs after removal of the pins. In a modification wherein the housing has a central depression in which the horn guards rest, the depression forms abutments for the outer races, and the small ends of the rollers are arranged adjacent.

Abstract: 536,131. Propelling ships. AKT.-GES. BROWN, BOVERI, & CIE. Oct. 24, 1939. No. 28592. Convention date, Nov. 22, 1938. [Class 114] [Also in Group XXXI] In a locomotive, ship or other vehicle propelled by gas-turbine plant including a compressor driven by the turbine, the power required to drive the compressor when the turbine is not working or is working at less than that power is used to brake the locomotive. In the diagrammatic locomotive arrangement shown a turbine 1 drives the compressor 2, directly and the wheels 4 through gearing 3. Power is supplied to the turbine by a gas producer 7 having a combustion chamber 8 in which fuel from a nozzle 9 is burnt with a small excess of air, the hot gases being mixed in a chamber 10 with a large volume of air to reduce the temperature to about 500‹C. suitable for the turbine. When the supply of fuel from a tank 11 is reduced or cut off, the turbine output will also be reduced or stopped, but as the compressor is geared to the wheels it will absorb temporarily the same power as when the turbine is driving and this power is taken from the wheels which are thus braked by the compressor. , The braking effect may be increased by throttling the air outlet of the turbine or the compressor. In a modification. the turbine drives directly the compressor and a dynamo which supplies electricity to motors driving the wheels.

Abstract: 155,975. Automatic Telephone Manufacturing Co., Ltd., Harrison, H. H., and Smith, S. R. Nov. 21, 1919. News-distributing systems; synchronous movements and synchronism indicators; distributor systems.-In a news-distributing system in which a central station transmits classified news to a number of substations over a single line, each class of news has a separate channel, and substations are so connected through distributors as to receive only the classes of news to which they subscribe. In an example, it is assumed that there are four classes of news. As shown, the switches LS, ST, ST2 are set for transmission by the central station A and reception by the stations I, II. A transmitting distributor TD has four sectors, each having five sections and being connected to a Baudot keyboard T1 - - T4. Receiving distributors RD1, RD2 of a similar nature at the substations have printers P11 - - P14, P21, P22, P24 connected only to the sectors corresponding tothe class of news to be received. To obtain synchronism between the distributors, the switch LS at the station A is moved to the position Sand the motor is started. Current passes via the commutator SC and switches (not shown) at the substations to lamps in front of the stereoscopic discs SD1, SD2 on the receiving motor shafts, and by this means the motors are synchronized, the receiving distributors being disconnected. The receiving distributors are geared to their motors so as to have a speed 5 per cent greater than that of the transmitting distributor, and at each revolution are held by a latch in the position shown, until released electromagnetically through the operation of their line relays LR1, LR2 by a positive impulse from the transmitter. This impulse is sent by means of an extra segment on the distributor TD, a second segment causing the restoration of the line to normal by means of a negative impulse. Auxiliary transmitting apparatus may be provided at substations, the transmitting distributor TD1 operating in the same way as the distributor TD, the switch STA 'being moved to the right and the switch LS at the station A being in the reset position to the right of that shown.
