Title: Improvements in electric starting systems for internal combustion engines
Filed: 1933-01-25
Abstract: 413,031. Starting prime movers. STARTOMATIC CORPORATION, 1627, West Pico Street, Los Angeles, U.S.A. Jan. 25, 1933, No. 2403. Convention date, Jan. 26, 1932. [Class 38 (iv).] In an automatic starting system for internalcombustion engines, the starter motor SM is controlled by an electromagnetic switch 7, the coil 14 of which is energized on closure of the ignition switch 11 under the control of two sets of contacts 16, 17 in parallel, one, 16, of which is normally open, and the other 17, normally closed, the contacts 16 being controlled electromagnetically in accordance with the motor current and the contacts 17 similarly in accordance with the voltage of the engine driven generator G, by coils 4, 21 respectively. The contacts are biassed to their normal positions by springs 25 and 19. Closure of an ignition switch 11 energizes the coil 14 of the starting switch 7 over the normally closed contacts 17 and causes closure of the switch 7. Cranking current through the coil 4 closes a holding circuit at 16 for the coil 14 so that energization of the generator coil 21 on rotation of the engine, and consequent opening of the contacts 17 does not de-energize the switch 7. On the self-operation of the engine, the motor cranking current diminishes and contacts 16 open to de-energize the coil 14 of the switch 7 which then opens. As long as the engine is self-operative the contacts 17 are maintained open by the generator coil 21 and the starting operation is only repeated if the engine stops unintentionally and de-energizes the coil 21. To prevent premature re-closure of the switch 7 should the engine make a false start, an additional coil assisting the coil 21 may be provided acting on the contacts 17 and energized from across the motor SM so that re-closure of the contacts 17 can only occur when the motor SM is at rest. Reference has been directed by the Comptroller to Specification 386,704.

Title: Machine for winding paper and similar material into rolls
IPC: B65H19/22
Filed: 1955-01-31
Abstract: 764,468. Winding webs. AKTIEBOLAGET AMALS GJUTERI OCH MEKANISKA VERKSTAD. Jan. 31, 1955 [Feb. 12, 1954], No. 2769/55. Class 100(1) A machine for winding paper comprising two winding stations 5, 6 and a device 21 for cutting a web of paper when the rolls attain a predetermined size is characterized by a switching tongue 19 which guides the free end of the web alternately to one of the two winding stations each provided with a plurality of rotatably driven rollers which, as the rolls increase in size, are swung away from stationary rotatable ' rollers driven in the same direction. As shown, a web 3 is unwound from a roll 4 by feed rollers 1, 2. Each winding station comprises four rollers, two rollers 7, 8 being rotatable about fixed axes, while rollers 9, 10 included in the station 5 and rollers 11, 12 included in the station 6 are carried by pivoted arms 13 and 14 respectively. The web 3 is guided by the tongue 19 into the station 5 through rollers 9, 16, the tongue 19 being pivotally mounted on the shaft 18 of the roller 16. The cutting device 21 is formed on the end of the. tongue 19 such that it cooperates with anvils 22, 23, when rocked by an armature 26 actuated by electromagnets 24, 25. The circuits including the electromagnets 24, 25 are closed by contacts 28, 29 and 30, 31, these contacts being opened by pins 32, 33 on the arms 13, 14 respectively. Downwardly inclined rollerways 34 guide completed rolls from the station 5 to a container 36, while a channel 37 allows rolls from the station 6 to slide axially on to an inclined plane 39 and into a container 40. In operation, as the diameter of a roll being wound in the station 5 increases the arms 13 are swung counterclockwise, the pin 32 eventually forcing the contacts 28, 29 apart such that the armature - 26 rocks the tongue 19 counterclockwise; thus the web 3 is cut by the device 21, the free end of the web being guided along the upper surface 20 of the tongue 19 to a feed roller 17 and the rollers 7, 8, 11 and 12. The arms 13 are swung into a horizontal position to permit the completed roll 35 to roll down the rollerways 34. In a modification, the tongue 19 has a guide roller and an inclined guide plate, while the cutting device is separate. In a further modification, the web 3 is fed mainly vertically and the tongue 19 has resilient metal strips 59 to guide the web.

Title: Improvements in or relating to memory systems
IPC: H03M7/00
Filed: 1964-01-27
Abstract: 1,002,296. Digital data storage. AMPEX CORPORATION. Jan. 27, 1964 [Feb. 28, 1963], No. 3397/64. Heading G4C. [Also in Division H3] In an arrangement for rapidly addressing a memory, the address signals are supplied to an address register and also directly to a decoding circuit so that the memory can be accessed by the address signals even before the address register circuits have acquired their steady stable states. As shown in Fig. 1, address signals from an external device 12 are applied via closed switches 22 both to a transistor flip-flop memory address resistor 20 and directly to a transistor decoding tree 16 to energize an output line for selecting an address in a memory 14 which may comprise single- or multi-aperture magnetic cores, tunnel diodes or cryotrons. When the flip-flop in the register 20 have acquired a settled state, switches 24 can be closed to maintain the address signals as inputs to the decoding tree 16, and switches 22 can be opened to disconnect the external device 12. In practice the functions of the switches 22, 24 are performed by appropriate timing signals. Address register stage, Fig. 2.- Each stage of the address register comprises a bi-stable circuit 30 and associated current steering circuit 32. Initially, zero potentials A, B, Fig. 4, are applied to timing control terminals 54, 70 (corresponding to the switches 24, 22 in Fig. 1). As long as the potential applied to terminal 70 is 0 volts, neither transistor Q3, Q4 in the circuit 32 can conduct. However, when the potential falls to - 6 volts as shown at B, Fig. 4, transistor Q3 or Q4, respectively, will conduct according as the input potential at 34 remains at - 1 volt or falls to - 4 volts, see Fig. 4. Assuming that the input potential at 34 does fall to - 4 volts, transistor Q4 conducts thereby causing the potential at an output terminal 38 to fall from 3.2 volts to 0 volts, the potential at the other output terminal 36 remaining at 3À2 volts. When subsequently the timing signal at A rises from 0 volts at which potential it prevents either of transistors Q1, Q2 in the circuit 30 from conducting, to 3 volts, transistor Q2 is enabled to become conducting owing to the 0 volts potential at output terminal 38, transistor Q1 remaining cut-off. Thus the circuit 30 has taken up a state representing the input signal, this state remaining unaffected by the subsequent return of the potential at control terminal 70 and input terminal 34 to their original values, and continuing until the return of the potential A at control terminal 54 to 0 volts causes the conducting transistor Q2 to be cut off and the circuit 30 to resume its original state with both transistors Q1, Q2 non-conducting. Decoding circuit.-The outputs 36, 38 of the circuits 32 in the address register are connected to a decoding circuit 16, Fig. 1, which consists of a tree arrangement of transistors (Fig. 3, not shown).
