Title: Improvements in or relating to a current supply control circuit for a single-phase resistance welding apparatus
IPC: B23K11/26
Filed: 1953-04-14
Abstract: 776,542. Welding current control circuits. FIAT SOC. PER AZIONI. April 14, 1953 [Aug. 5, 1952], No. 10198/53. Class 38 (4). In a single-phase resistance welding apparatus current supply control circuit of the type, Fig. 1, having a pair of ignitrons 2, 3 connected in reverse parallel with each other and in series with, across an A.C. source applied to terminals 4, 5, the primary winding 1<SP>1</SP>, 1<SP>11</SP> of a power welding transformer, and each ignitron having its ignition controlled by a respective thyratron 7, 8 connected in series with its ignitor 9, 10, there are provided an automatic timing circuit, Fig. 2, which produces a succession of alternate transformer energization and de-energization periods, a manually operable switch P for causing and stopping such succession, and a pair of mechanically coupled contact pairs 11, 12 directly operated by the coil of one B2 of a number of timing circuit electromagnetic relays and connected one contact pair in each thyratron circuit: the timing circuit further comprises the primary winding of a transformer TR which is energized when the switch P is closed and whose secondary winding charges a condenser C1 in the circuit of another relay 21 which when energized by the condenser when the latter is sufficiently charged closes its contact 1Z which permits energization of the coil of another relay X2 whose contacts 2X close to complete a discharging circuit for the condenser and whose contacts 1X open to deenergize the transformer. Also when the switch P is closed the coil of another relay Y1 is energized to close its contacts 1X and thereby permit energization of the relay B2 which by closing its contact pairs 11, 12 permits welding current to flow, and when contacts 1X open relay Y1 is de-energized which stops the welding current flow. The discharge time of condenser C1 through a resistor R2 is adjustable and when it has discharged relay Z1 is de-energized and through relay X2 commences again the welding current flow, thus producing the succession of alternate welding and non-welding periods during which latter workpieces are interchanged, Condenser C1 is charged over a rectifier RD and a resistor R1, and its charging time may be varied by varying R1 and by connecting or disconnecting in the circuit by means of switches L, M another resistor R and a condenser C2. As shown, the contact pairs 11, 12 are connected in the anode circuits of the thyratrons 7, 8 but iii a modification (not shown) they are connected serially between the thyratron cathodes and the ignitron igniter 9, 10. In addition to the described control of the duration of the welding and non-welding periods, phase-shifting networks 19, 20, an example of which is described in the Specification, permit adjustment of the effective value of the welding current by varying the starting point of current flow in each half-cycle of the source voltage.

Title: Introducing signal to charge-coupled circuit
IPC: H01L29/762
Filed: 1974-03-07
Abstract: 1456255 Charge transfer devices RCA CORPORATION 7 March 1974 [13 June 1973] 10231/74 Heading H1K The amount of noise generated in introducing charge into the input of a charge coupled circuit is reduced by first feeding the charge into a potential well separated from the circuit input by a potential barrier, reducing the effective well depth to spill charge from the well to leave a charge proportional to the new well depth, which is then fed to the input by lowering the potential barrier. In the Fig. 2 arrangement a voltage pulse on electrode G 3  provides the barrier and reduction of the voltage on source diffusion S at time t 2  as shown with the voltages on electrodes G 1  and G 2  held constant causes the reduction in well depth, after which the pulse is removed from V 3  at time t 4  to allow the retained charge to flow to the well under the first phase electrode of a three-phase system, the cycle being repeated while the charge packet is propagated. In an alternative arrangement, Fig. 4, an additional electrode 30 maintained at a fixed voltage relative to the source is provided, changes in source voltage reducing the depth of the well under electrode 34 to a value determined by the difference in potential between electrodes 32 and 34, propagation being by a conventional two-phase system. In a modification of this the source voltage is fixed and the well depth reduced by altering the voltages on electrodes 32 and 34 which differ by the input voltage which thus determines final well depth. Alternatively electrodes 32 and 34 are at the same potential, the difference in thickness of the insulation between them determining the well depth. A similar result can be achieved by differences in charge in the insulating layer, in surface doping of the substrate, or in the work functions of the materials of electrodes 32 and 34. The arrangement may be used to supply " fat zero " charges in shift registers and imaging arrays to improve charge transfer efficiency.

Title: Data storage control apparatus for a multiprogrammed data processing system
Inventor: COULEUR JOHN FRANCIS
IPC: G11B5/012
Filed: 1969-02-26
Abstract: 1,263,742. Data storage; computers. GENERAL ELECTRIC CO. 26 Feb., 1969 [27 Feb., 1968], No. 10386/68. Headings G4A and G4C. A storage control system, in a data processing system, can control data transfer operations between two storage members without intervention of the processor of the data processing system, under control of control-word-pairs, each pair including a function code and a link address to the next pair, which next pair is retrieved from storage without the intervention of the processor. In a multi-programmed computer system, two memory controllers control communications between four core memories and two processors and two I/O controllers and also between the core memories and an extendedmemory controller linked to a disc (or drum) memory. Transfer e.g. of programme segments, between core and disc, is initiated when a "connect" instruction is executed by a processor causing a peripheral control word to be supplied from core to the extended-memory controller which responds to an operation code in the word to use an address in the word to address core to obtain the first word of a first pair of data control words. The second word of the pair is obtained from the next consecutive address. The first word of the pair specifies a core address, and a disc address, and the second word specifies the required operations, e.g. direction of data transfer, and the core address of the first of the next pair of data control words. In a core to disc transfer, 64 words are read from consecutive core locations, starting at that specified in the first word of the pair of data control words, and supplied in turn to one-word holding registers in the extended-memory controller. When the 4 registers are full, their contents are transferred to 16 one-character shift registers (4 characters per word) which are shifted out together to respective disc tracks, at the disc address specified by the first word of the control word pair. A disc to core transfer is the reverse of the above, using the same registers. The 64-word transfer terminates on reception of an "end sector" signal from the disc memory. The next pair of data control word is now retrieved.
