Abstract: 1,051,463. Inverters. GENERAL ELECTRIC CO. Feb. 22, 1965 [March 19, 1964], No. 7463/65. Heading H2F. [Also in Division H3] In a transistor inverter circuit having the primary windings 11, 12 of a saturable transformer connected in series with the collector and emitter electrodes of transistors 15, 16 and primary windings 21, 22 of the output transformer 19, the conduction of either transistor can be stopped by a control voltage applied via transistor 361 to an inhibiting winding 351 which has a loading effect on the secondary windings 13, 14 so as to prevent them from developing sufficient base current to maintain their associated transistors 15 or 16 turned on. The circuit is started by current from the D.C. supply 17, 18 flowing through the starting resistor 23 and secondary winding 13 so as to turn on transistor 15 but if the current through the primary winding 11 is not great enough to supply the core losses of the saturable transformer, transistor 15 will cease to conduct. This current can be produced by the main load or an artificial load, if the inverter is to start on noload, applied to the secondary winding 24 of the output transformer or by no-load windings 31 connected across the primary windings of the output transformer. The switching action of the saturable transformer then causes transistors 15 and 16 to conduct alternately. Diode 25 prevents the transistors from being on for unequal periods which would give rise to an unbalanced output. Also to prevent undesired harmonics in the output, i.e. to reduce the unbalance and prevent an over-voltage on the output transformer primary windings 21, 22, saturable reactions 42, 43 are provided so that if one becomes saturated a signal is supplied via blocking diodes 46, 47 to the base of transistor 362 which operates inhibiting winding 352 to stop conduction of either transistor 15 or 16. The circuit can similarly be protected against overload by supplying a signal voltage corresponding to the overload current through resistor 26 to the base electrode of transistor 363 connected to inhibiting winding 353. Alternatively the control signals may be combined and supplied to a single inhibiting winding. The transistors may be of the silicon junction PNP or NPN types.

Abstract: 1,053,512. Wrapping-machines. GEVAERT PHOTO-PRODUCTEN N.V. Jan. 29, 1964 [Jan. 30, 1963], No. 3837/64. Heading B8C. In the operation of a machine for wrapping sheets, in particular sheets intended for photographic purposes, a stack thereof is placed on a length of web 24 in a position overlying a spring- loaded vertically reciprocable member 13. The web, delivered by feed rolls 19, 20 and cut by a guillotine 23, is preferably a laminate of paper, aluminium and polyethylene. A vertically reciprocable member 14 is lowered on to the stack to force it downwardly until the upper horizontal surface of member 14 is flush with supports 11, 12, the stack being flexed between co-operating the upper and lower curved surfaces of members 13, 14 respectively, Fig. 3 (not shown). During this movement the laterally extending portions of the web are folded upwardly; thereafter they are folded automatically, e.g. by a pair of horizontally reciprocating folders, or manually, over the upper surface of member 14 to be heat sealed together by a vertically reciprocable sealing unit 15. A ribbed profile 31 may be provided to improve the seal. The member 14 is raised and the stack, now provided with a sleeve, is slid off the member, whereupon the sheets recover their flat condition and tension the sleeve. The ends of the sleeve are closed by folding and/or heat sealing. Preferably the upper and lower sheets of the stack are of cardboard to protect and rigidify the stack. As an alternative to heat sealing, adhesive tape may be used.

Abstract: 1,231,287. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 15 Aug., 1968 [27 Sept., 1967], No. 39071/68. Heading G4A. A data processing system comprises a main store having word positions for storing variable length multi-word operands which start and end at any byte position within a word position, means to transfer at least one operand from the main store to an auxiliary store a word position at a time, and a processing unit for identically processing successive words of at least one operand stored in the auxiliary store, a byte at a time or a word at a time according to predetermined conditions, under the control of control data from the main store. The auxiliary store can hold a word (four 8-bit bytes) of each of two operands from the main store, the main store addresses (word and byte) of the first byte of each operand, and a count field. The count field specifies the number of bytes per operand, except in decimal operations when the two halves of the field specify the numbers of bytes in the two operands respectively. The count field can be decremented by the arithmetic and logic unit as processing proceeds. The byte portions of the addresses stored in the auxiliary store can be transferred to and stored in a sub-unit (byte) accessing and modifier circuit which can increment and decrement them (according to whether bytes are taken going leftwards or rightwards along the words). This circuit also stores a 4-bit mask which is updated as each byte is processed to indicate which byte positions are to be overwritten when results of the processing are returned to overwrite one operand in the main store. Processing involving two operands is done a byte at a time unless the circuitry detects that bytes to be combined are correspondingly positioned in their respective words when complete words are processed a word at a time, but incomplete words (e.g. the last word position, if the operand does not end on a word boundary) are still processed a byte at a time. Processing involving a single operand can be done a word at a time for incomplete words. Processing is serial by byte even in the "word at a time" processing. In "word at a time" processing, the system remains in execute mode during the processing of a complete word, using the same control data (a microprogramme word read from main store into a control register) repetitively, and only then transfers to another mode, whereas with "byte at a time" processing, transfer to another mode occurs after each byte. The other modes provided are for transfer of words between the main and auxiliary stores and updating of the count field. Modes are changed by microprogramme branching under control of the incremented/ decremented byte addresses in the sub-unit accessing and modifier circuit and the decremented count field from the auxiliary store via a status register.

Abstract: 1232421 Monogrammic sign control STEWART WARNER CORP 9 May 1968 22043/68 Index G4H 1A 6A 6B CE 7B 9E 14B A monogrammic sign whose display elements (e.g. lamps) are arranged in a cartesian array of rows LR1-7 and columns LC1-5 Fig.2 (not shown), is controlled by a system exemplified in Fig.4, which comprises an analogous array of control elements 1301-1304, each such element corresponding to a display element and enabling the latter on being actuated by means 600 (e.g. a decoder) responsive to data input means 500 (e.g. a keyboard or a computer); means 750 sequentially strobes each column LC1-5 to actuate display elements corresponding to the enabled control elements. As described, the control elements 1300-1304 are NAND gates forming part of a lamp encoder circuit 754. If it is desired to display e.g. the letter T, a low going signal will be impressed on line 1208 by T-gate 602-T in decoder 600. This causes a signal to be supplied via NOR gates 1306 to the shaded NAND gates: this encodes the character T, and a start signal is sent on line 1316 to strobe counter circuit 750. Each of the LC1-5 strobe pulses in NANDed with the encoded signals to direct signals to the rows LR1-7; their simultaneous receipt with the column signals causes selected lamps to glow. The number of conductors is reduced by combining inputs to various gates which are common to a number of different display characters. Thus, all the lamps in column LC1 are common to the characters E, F, D, K, M, N, P, R and W: so the decoder output lines for all of these characters are NOR'd at gate 1308 to produce a single line for signalling elements 1300a-1300g.
