Title: A Paper Advancing Device for Photographic Developing Apparatus
IPC: G03D3/13
Filed: 1946-07-19
Abstract: 628,970. Photographic processing apparatus. ZOLLINGER, W. July 19, 1946, No. 21697. Convention date, July 30, 1945. [Class 98 (ii)] [Also in Group XXX] Means of the kind described in Specification 412,023 for conveying cut paper sheets through adjoining photographic processing baths is characterized in that each bath is provided at each side with an elastic cord carrying pivoted driving members and passing over upper driving and lower idler pulleys, these driving members engaging the edges of the paper sheet so as to move the paper with them and pass it out of the bath between a cylinder and pressure rollers to the next bath, two paper-supporting cylinders being arranged coaxially with and between the upper and lower pairs of pulleys. As shown, at opposite sides of the bath 1 are disposed guide plates 6 separated by cross-rods 7. Pulleys 13, 14 are carried by shafts 9, 10 which are journalled in bushes 8 attached to the plates 6 and which carry rubber-covered papersupporting cylinders 11, 12. An endless spiral spring steel wire 16 passes round each set of pulleys in grooves 13a, 14b and the driving members 15 are frictionally secured thereon by bushes attached to their main arms 15a. Two guide channels 17 on the plates 6, spaced wider apart at the bottom than at the top, locate spherical boss ends 15b of the driving members 15, whilst fingers 15c, 15d arranged on opposite sides of the main arm 15a at 30 and 60 degrees to it respectively form a paper-receiving V. When resting on the upper pulley 13 the main arm 15a is inclined upwardly at about 30 degrees to the shaft, but when the boss 15b reaches the lower end of the guide channel 17 the arm 15a becomes inclined upwardly at 15 degrees to the parallel shaft 10 due to the slope of the grooves 14b causing the members 15 to tend to slide towards each other under the influence of the wire 16, thus causing the members to produce a " clamping " action on the edges of the paper sheet. Between the plates 6 are disposed paper guiding members 22. The plates 6 carry upper extensions 6f in which is supported the shaft of a cylinder 26 whilst its co-operating pressure rollers 27 are carried by a frame 24 of inverted U-shape bolted to the extensions 6f, the axes of the two outermost rollers being fixed whilst the other two are freely movable in slots in the frame. A number of baths 1 are housed in a double-walled outer casing 2 and the upper shafts 9 of each bath are driven by a chain engaging the sprockets 4.

IPC: H04M1/652
Filed: 1953-08-06
Abstract: 725,902. Substation equipment. PROMUNDO. Aug. 6, 1953, No. 21739/53. Class 40 (4). A phonographic device for answering an incoming call is provided with means whereby a calling subscriber may cause repetition of part of the recorded reply message by uttering a sound of more than a predetermined length. As shown, relays 9 and 25 respond to speech impulses incoming over exchange line 1, 2 or from pick-up 6 and bring up a slow-releasing relay 45 which completes a circuit for a clutch magnet 54 so that the reply record 7 is set in forward motion. The relays 9 and 25 are stated to be energized and released by each word uttered by the calling subscriber or the reply record 7. If the calling subscriber fails to understand part of the reply message, he utters a sound of more than a predetermined length to cause the operation of a relay 51. This briefly switches the energizing circuit from clutch magnet 54 to a reverse clutch magnet 53 so that the reply record 7 runs backwards and then forwards again. If, however, a signal of the predetermined length is transmitted by the pick-up 6, a relay 20 is energized to prevent operation of relay 51 and consequent undesired repetition.

Title: Improvements in recording apparatus
IPC: G11B20/12
Filed: 1964-05-29
Abstract: 1,010,316. Starting recording apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 29, 1964 [June 28, 1963], No. 22280/64. Heading G5R. Gaps between blocks of information recorded on a storage medium are made more uniform by controlling the start time of the apparatus according to the interval between completion of recording of one block of information and the receipt of a signal to start writing a further block of information. In Fig. 1 a write block latch 12 is set by a write instruction on line 10 and re-set by a signal on line 13 when a block of information has been written and checked. The signal on line 13 also actuates a single-shot multivibrator 17 which provides an output for about ¢ millisecond so that if a further write instruction occurs within this period there is an output from AND gate 18. The output from gate 18 passes to units 31 and 32 to provide a capstan actuator signal and also passes to a short delay unit 19(a) which provides a write signal after 4 milliseconds. If the write instruction on line 10 occurs after the ¢ millisecond period of unit 17, gate 22 is opened by an inverted signal from unit 17 and a signal passes through switch 24 to operate the capstan and to initiate writing via a long delay unit 19(b) which provides a delay of 5 milliseconds. If there is an output from gate 18, gate 22 is inhibited via units 38 and 39. With switch 24 in its other position the output to the capstan and delay units is taken from gate 23 which is not opened until 4 milliseconds after a signal on line 13, this delay being provided by unit 26. In this mode of operation the inter-record gap is more uniform since the capstan is allowed to stop being re-started, but in the first mode of operation the access time is shorter.

Title: Method for the oxygen-gas delignification of lignocellulosic material and apparatus for carrying out the method
IPC: D21C3/00
Filed: 1975-05-23
Abstract: 1505529 Oxygen gas delignification MO OCH DOMSJO AB 23 May 1975 [14 June 1974 22 Jan 1975] 22637/75 Heading D1P [Also in Division B1] The level of carbon monoxide formed during the oxygen delignification and/or bleaching of ligno cellulosic material is controlled within the limits of 1-12% by volume of the treatment gas to provide safety from explosions and improved selectivity i.e. reduced levels of cellulose depolymerisation for a given kappa number. The control is effected by removing quantities of oxygen and carbon monoxide containing gas, from the treatment, removing a part of or all the carbon monoxide e.g. by absorption, adsorption, molecular filtration or chemical conversion to carbon dioxide, and recycling the gas to the treatment vessel. Further control is effected by adjusting the temperature of the treatment e.g. by admitting gas at a different pressure and/or temperature to the vessel, and reducing the level of steam heating correspondingly. Manganese and/or magnesium compounds may be present to reduce cellulose decomposition. The ligno cellulosic material may be pre-treated with compounds which remove iron compounds. Uniformity of treatment gas composition is attained by moving the gas relative to the pulp, preferably in countercurrent as by introducing the pulp downwardly into a tower through which the gas is being passed upwardly. An apparatus for carrying out the method comprises a reaction vessel and a pressure container provided with a catalyst bed for converting carbon monoxide to carbon dioxide, the vessel and container being, connected by conduits providing for circulation of gaseous mixture from and to the vessel with intermediate passage through the catalyst bed. Control of the temperature and/or pressure of the gas may further be effected in a bypass conduit connecting the circulating conduits and omitting the catalyst bed.
