Title: Improvements in or relating to photographic contact printing
IPC: G03B27/22
Filed: 1939-03-20
Abstract: 527,835. Cutting webs. KONIG, P. March 20, 1939, No. 8883. [Class 31 (i)] [Also in Group XX] In a method of continuously producing photoprints (see Group XX), the prints are automatically severed from a web 11 of printing paper by means of a pivoted guillotine cutter 18 the blade 29 of which is operated by a cam 33, Fig. 5, forming part of the driven member 28 of a onerevolution electro-magnetically operated clutch, the driving member 34 of which is rotated by a motor 19. Engagement of the clutch is caused by the passage of one of punched gauge marks 11a, 11b in the web 11 between a contact member 22 in the table 17, and a spring contact 23. The clutch makes one revolution, causing the blade 29 to make one cut, and comes to rest. During the act the web is held by an eccentric operated clamping-bar 42. If it is desired to cut away the margins of adjacent prints, the gauge punchings are arranged in pairs 11a, 11b ; alternatively the knife 29 may have two spaced cutting edges to remove the intervening strip in one cut. The gauge punchings may be replaced by metal clips secured to the edge of the web and forming contact members for closing the clutch circuit. In a modification, Fig. 7 (not shown), a shearing blade is guided relatively to the web by means of pins and inclined slots so as to obtain a drawing cut. In this case, the clutch member is connected to the blade by means of a thrust rod.

Title: Improvements relating to cylindrical printing surfaces
IPC: B41F27/10
Filed: 1920-03-27
Abstract: 169,470. Mascord, G. W. March 27, 1920. Printing-surfaces.-Printing-cylinders of the kind provided with dovetail or under-cut longitudinal ribs to receive a plurality of intaglio or other printing- plates, have these ribs slightly tapered along their longitudinal edges so that the printing - plates with .correspondingly formed edges or grooves may be wedged tightly in position. A continuous periphery may be obtained by forming the ribs of the same height as the thickness of the printing-plates, or the edges of these may meet over the tops of the ribs to provide a continuous printing-surface. The cylinders are also provided with end clamps for securing the plates in position, and with screw-actuated levers for releasing them. As shown, the cylinder a is adapted to receive two sets of four printing-plates a', a<2>, a<3>, a', by means of the dovetail longitudinal ribs c, and a circumferential rib d which may be dovetail, undercut, or plain, the longitudinal ribs c being tapered, as shown in Fig. 1. The plates are clamped tight up against the rib d by segmental clamps e mounted on the end plates f of the cylinder. These clamps are carried by screw-studs h, guided by pins g passing through holes in the end plates f, and are shaped at e<1> to engage the bevelled or vertical edges of the printing-plates, the screw studs h being fitted with milled-headed clamping-nuts i and locking-nuts j. Four plate-releasing devices are mounted on the cylinder, one for each pair of plates a<1>, a<2>, opposed in line, as shown in Fig. 3. Each device comprises a lever m projecting through a slot in the periphery of the cylinder a into a dovetail or other recess formed between the meeting edges of the plates a<1>, a<2>, the inner end of the lever m being forked to engage pins on a nut working on a threaded portion l of a rod k mounted in bearings in the cylinder end plates f. By rotating the rod k by means of the heads n in one or other direction, either of the plates a', a<2> may be moved outwardly and released from the wedging action of the ribs c. The latter may be shaped as shown in Figs. 4 and 5, and of a height to be continuous with the surface of the printing-plates, or as shown in Fig. 6, wherein the edges of the printing- plates meet over the ribs to produce a continuous printing-surface. The longitudinal grooves may be disposed laterally or centrally with respect to the printing-plates or in any other position.

Abstract: 236,660. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. April 10, 1924. Electrical systems, automatic.-In track relay systems of the kind in which the relay is held energized by current less than that supplied to cause the relay to pick up, electric cells are used to obtain the required current variations, and they may be applied at the current feed end, or at the relay end, of a track system. In the former case the arrangement is such that an increased current is obtained when a train passes off the section in either direction, by a momentary increase in the supply voltage. In the latter case the cell, besides giving the required increased current, also serves to give a more certain de-energization of the track relay when shunted by a train. Both arrangements give a progressive change in current, and the two arrangements may be used in combination. Fig. 1 shows a feed battery 7 in series with a feed resistance 8 and auxiliary relay 9 across the insulated rails 1, 2. Normally, the track relay 5 is energized and auxiliary relay 9 is insufficiently energized to pick up its armature 10. Under these conditions, resistance 8 and relay 9 are shunted through a resistance 13 and electrolytic cell 11 over the back contact of armature 10. When a train enters the section, relay 5 is de-energized and armature 10 is lifted. The cell 11 is thereby connected over front contact of armature 10 so as to be charged up by an auxiliary battery 12. When the train passes off the section, the parts return to the position shown, the cell 11 discharging in a direction to aid the feed battery 7 in energizing relay 5. Fig. 2 shows rail-sections 13<1>, 14 supplied at one end by a usual arrangement of battery 17 and feed resistance 18. At the other end the 'track relay 19 is connected in series with a resistance 21 shunted bv an electrolytic cell 22. Both resistance 21 and cell 22 are shortcircuited when the relay armature 20 is released and rests against a back-contact shown. Normally, relay 19 is energized and cell 22 is charged by battery 17. When a train enters the section, short-circuiting relay 19, cell 22 discharges through the relay in a direction opposing current from battery 17, so aiding in effective de-energization of the relay. When the train passes out of the section relay 19 is energized, resistance 21 being operative to reduce the current when armature 20 has lifted. The cell 22, during its charging up, also acts as a gradually increasing resietance in parallel with resistance 21, so that the maximum effective resistance in the circuit is attained only when the cell is charged. In a modilication, the back-contact for armature 20 is omitted, the cell 22 then acting in the abovedescribed manner to secure a decreased current when the relay 19 is energized. The electrolytic cells may be of the type described in Specification 248,466, [Class 37, Electricity, Measuring &c.], using mild steel electrodes in caustic potash solution.

Abstract: 976, 499. Electric digital-data-storage. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 14, 1961 [March 16, 1960], No. 9300/60. Heading G4C. A data word storage arrangement for an electronic digital computer comprises storage locations divided between a high access speed store and a lower access speed backing store, transfer between the stores taking place automatically if a desired storage location is not in the high access speed store. As described, a computer includes a high access speed store 10 comprising eight magnetic core store matrices storing in all sixteen blocks of 512 words each, and a lower access speed backing store 11 comprising four magnetic drums storing in all 512 blocks of 512 words each. Each block of data in the storage arrangement is assigned a characteristic block number, the block numbers of the sixteen blocks actually present in the store 10 being set up on triggers in comparator circuits 21 (Fig. 2, not shown). In operation, an instruction word is applied to a control system 14, the digits d0-d22 constituting the address of a word required; digits d14-d22 represent the number of the required block, digits d3-d11 represent the location of the desired word within the desired block, and digits d0-d2 relate to the required part of the desired word. The digits d14-d22 are compared simultaneously with the block numbers stored in the circuits 21, and if equality is attained, a signal is emitted over one of the lines 19a-19p to cause a code signal generator 15 to transmit over a bus 13b the representation of the storage position 1-16 in the store 10 occupied by the desired block, a signal also being fed over a line 37 to the control system 14 to initiate the appropriate machine operation. If the digits d14-d22 define a block number different from any in the circuits 21, a non-equivalence signal on a line 39 causes control to pass temporarily from the system 14 to a transfer control system 27 which initiates operation of a transfer sub-routine stored at 29. This causes a block of words adjacent to the previously transferred block to be transferred from the store 10 to the backing store 11, the address at which the block is entered in the store 11 being determined by its block number which is also stored in a so-called V-store 31 at an address represented by its location in the store 10. This address in the V-store is now supplied with the nine digit block number d14-d22 which is sent to the circuits 21 and to the address selecting means 16 of the store 11. The destination address 1-16 is sent over a bus 13c and the required block transmitted to this address over a bus 26 from the store 11. The computer then reverts to the normal control system 14.

Abstract: 766,989. Multi-stable state circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 18, 1954 [April 7, 1953], No. 9471/53. Class 40(6) In a multi-stable state circuit comprising switchable devices coupled to form a closed chain so that a pattern of conductivity can be progressed successively around the chain in response to switching pulses a delay is introduced following the transfer of the condition of conductivity from one device to the following one such that the circuit can only operate in a single mode at one time. Fig. 1 shows a circuit of the type described in Specification 766,988 [Group XIX] in which discharge tubes V1...VN are connected in a closed chain and in which normally all tubes but one are in the non-conducting condition. The position in the chain of the tube which is conducting at any instant being progressed around the chain by switching pulses 1, 2 applied to leads A and B. Interposed between tubes VN and and V1 is a cathode-coupled multivibrator comprising tubes 3, 4 so that when the condition of conductivity reaches tube VN the multivibrator is triggered over and on reversion triggers tube V1 to the conductive condition. The time of reversion which is determined by the time constant of network 8, 9, 10 is between N/2 and N periods of the switching pulse where N is the number of stages in the chain. Since the multivibrator is free-running it will automatically trigger tube V1 to propogate a condition of conductivity round the chain. In a modification shown in Fig. 2 a condition of non-conductivity is progressed along the chain comprising tubes V1...VN as described in Specification 766,987 [Group XIX] and a multivibrator comprising tubes 14, 15 interposes a minimum delay, determined by the time constant of network 16, 19, between the time of two successive transferences of the non-conducting state from VN to V1. The multivibrator may be replaced by another relaxation device such as a blocking oscillator.
