Abstract: 1497468 Facsimile J P BRUCKER 7 June 1975 24527/75 Heading H4F Half tone colour separation negatives for facsimile reproduction, are produced having differing screen pattern angles α to avoid MoirÚ pattern defects. A colour original is mounted on a drum 28, Fig. 1. The separations are produced on films carried by drums 29 to 32 mounted on a common shaft 22 with "original" drum 28. The individual films are exposed by respective dot generators 43 to 46 rigidly attached to a slide 40 driven along a path parallel to shaft 22. Slide 40 carries a scanning detector 42. Dot generators 43 to 46 comprise respective CRTs 47 the displays of which are imaged on to the films by lenses 48. Each CRT 47 has its vertical deflection axis rotated through an angle # from the line direction 52, from which the requisite separation screen pattern angles α (where α = # Œ 45‹) are obtained. A clock signal is recorded on a magnetic strip 55 read by a head 54. Line start signals are obtained from a photodetector 56 registering the passage of a tab 57. Black is screened at α = 45‹ (# = 90‹), yellow at α=0‹ (#=45‹), magenta at α = + 15‹ (# = + 60‹) and cyan at α = - 15‹ (# = -60‹). Fig. 17 shows the magenta screen pattern. A to F represent consecutive scan lines. Lines 94 indicate the vertical deflection axis of the relevant dot generator and line 144 shows the screen pattern axis. As line A is scanned in direction 52 successive dots 0, 3, 6, 9, 1,...are exposed which are incremented along lines 94 by an amount yielding the + 15 degree screen angle of the magenta separation. The other separation's screen patterns are formed in a similar manner described with reference to Figs. 15, 16, 18 (not shown). Logic circuits for controlling the dot generators are described with reference to Figs. 2 to 14 (not shown). The separations may be enlargements. The recording medium may be lithographic plates, gravure plates, deformable plastic sheets, metal plates and paper sheets. The record medium and original may be mounted on flat surfaces scanned by a reciprocating scanner. Dot generators may be modulated lasers, vibrating styli, modulated arc light or electrostatic ink dot accelerator.

Filed: 1973-05-23
Abstract: 1429199 Timing circuits; transistor amplifiers RCA CORPORATION 23 May 1973 [5 June 1972] 24534/73 Heading H3T A timing circuit comprises an operational amplifier i.e. a high gain D.C. amplifier, including transitors Q 1 , Q 2  connected in a differential circuit configuration, a charging circuit R5, S operable for charging a storage device C connected to the control electrode of transistor Q 2  to a potential differing substantially from a reference potential applied to the control electrode of Q 1  in a sense to cause an output signal to be provided at 6 and to initiate discharge of C primarily through the transistor Q 2  and an arrangement R1-R4 for selectively determining the current through Q 2  for controlling the rate of discharge and hence the duration of the output signal. The amplifier is an operational transconductance amplifier having an additional control terminal at 5. The amplifier may include a current mirror D 1 , Q 3  as a current source and further current mirrors Q 4 -Q 9  as collector loads for Q 1 , Q 2 . In operation, the collector current of Q 2  will exceed that of Q 1  when capacitor C is charged by momentarily depressing a button S and as the output current supplied by transistors Q 8 , Q 9  exceed that of Q 5 , Q 6 , the difference will flow as a source current into a load circuit formed by transistors Q 12 , Q 13  and a triac T. When the charge voltage of C falls below the reference potential at base of Q 1 , a change of state of the output signal occurs and triac T is cut off. By interchange of input terminals 2, 3, the circuit provides an output signal at the end of a timed duration.

Abstract: 1294791 Automatic exchange systems SIEMENS AG 19 April 1971 [17 Dec 1970] 24632/71 Heading H4K In a computer controlled exchange employing a plurality of equipment groups each of which includes a sectionalized switching network and an interface unit for communicating over a duplicated bus system with a pair of data processors, the latter contain a memory map' indicating the free/busy status of every equipment in the exchange, and the equipment groups each have sets of carrier frequency terminals connected thereto and contain a monitoring device which in the event of a fault on any carrier channel of a set causes, via the interface, all the members of this set to be marked busy in the map. As can be appreciated from the drawings the equipment groups AF1 . . . AFn are connectible via respective interfaces AS1 . . . ASn and duplicated data buses U1 to duplicated buffers SS1, SS2 from which data is read-out to either central control ZS1, ZS2 on demand by the latter. The controls incorporate respective programme stores PS1, PS2 and a plurality of stores ZJS which contain inter alia the memory maps. Data between a group and its interface is transmitted in parallel mode and a transmission may be initiated by either an individual equipment within a group or by the interface (on central controls orders). In a bus U1 data is sent in serial mode upon application from either end and each message contains a first word indicating message length, one or two words indicating the individual equipments' identity and up to four words in respect of information. Each equipment group contains a modulating/demodulating carrier terminal unit TE whose carrier frequency channels are terminated directly or indirectly via carrier frequency line circuits RS on the switching network. The channels are monitored for faults by device PA which has access to the interface and hence to central control over parallel data bus U11 in the same way as any other individual equipment of the group. The address of the monitoring device is sufficient to allow central control artificially busy the network terminals having access to the carrier channels. When the fault is cleared the monitoring device reapplies to central control for cancellation of the busy markings.
