Title: Improvements in or relating to continuous rod cigarette-making machines and control systems therefor
IPC: A24C5/31
Filed: 1963-05-09
Abstract: 1,089,764. Cigarette making machines. MOLINS ORGANISATION Ltd., D. T. N. WILLIAMSON and M. A. PYM. May 8, 1964 [May 9, 1963], No. 18422/63. Heading A2C. A cigarette making machine of the continuous rod type comprises means for forming a tobacco filler and means for apply adhesive to one edge of a paper strip folded round the tobacco filler, means for heating the seam of the paper strip, the adhesive applying means and the heating means being independently movable between operative and inoperative positions, control means operable to move the heating means into operative position and a predetermined time thereafter to cause operation of rod breaking means and a detector device to give a warning whenever the rod is not properly sealed wherein the control means is arranged to bring the detector device into operation a predetermined further time after operation of the rod breaking means. Tobacco conveyed by the lower run of an overhead suction conveyer 1 is formed into the tobacco filler, is enfolded in cigarete paper and passes to the adhesive applying device 4 and to a heater 5 to secure the seam. The tobacco filler travels past a rod breaking device 6, through a unit 7 detecting tobacco density and controlling a trimmer 8 for the tobacco feed, is cut into cigarette lengths by a cut off device 9 and is conveyed by a suction wheel 10 to a fluted drum 11 and to an output machine. The detector device associated with the wheel 10 responds to pressure variations in the suction system due to missing or improperly sealed cigarettes. In operation, the main switch is closed, the master relay operates and starts tobacco and paper feed then brings the adhesive applicator into operation and operates a further switch. A second relay is energized closing two pairs of contacts which energize a solenoid controlling the heater. A micro switch closes before the heater reaches the operative position to energize a relay the action of which is delayed by a capacitor. When a further pair of contacts close, a further solenoid is energized controlling the rod breaking means. Two further pairs of contacts of the first relay open and close respectively to remove the short circuit from the detector device which is either pneumatic or photo-electric. In an alternative circuit an additional solenoid retains the heater in operation and the switch for the rod breaking circuit is controlled by a cam driven by the solenoid controlling the heater.

Abstract: 1294281 Encoder for magnetic recording HONEYWELL INFORMATION SYSTEMS Inc 8 June 1971 [6 July 1970] 19523/71 Heading G4C An encoder translating an input NRZ waveform into a self-clocking three frequency waveform has a clock 10 receiving clock pulses and providing two phase clock signals #1, # 2 . The # 1  signals advance data in a register 100 so that the bit intervals of the data coincide with the trailing edge of the 91 pulse. The data bits and # 1  pulse feed a bi-stable 20 which provides output waveforms F2, F2 delayed by 1 bit from the input waveforms. F2 and #2 feed a NAND gate 24 and F1 from NAND gate 22, F2 and #1 feed a NAND gate 26. The output from the gates is combined in NAND gate 28 and feeds bistable 30. NAND gate 24 provides an output F2.#2 and produces an inverted #2 pulse in the centre of each "1" of the delayed waveform F2 while NAND gate 26 produces an inverted pulse between two successive zeros of the delayed waveform F2. The pulses fed via gate 28 produce at F6 a transition in the centre of each "1" bit of the delayed waveform and a transition between two successive "0" bits in the delayed waveform (Fig. 2, not shown). Fig. 1a (not shown) illustrates the two phase clock which has a bi-stable similar to bi-stable 20 with the inverted output feeding the input and with two input NAND gates each receiving clock input pulses and each receiving a separate one of the bi-stable outputs.
Patent GB-1365991-A (GB)
Title: Apparatus for optical character recognition reading and repro duction
IPC: G06V30/196
Filed: 1972-04-27
Abstract: 1365991 Character recognition; editing ECRM Inc 27 April 1972 [6 May 1971] 19548/72 Headings G4H and G4R  A character recognition system involves the scanning of a number of areas of a characterbearing document, each area having dimensions large compared with the character height, e.g. the area may cover parts of several lines of characters. The characters are recognized in an order that is unrelated to the physical order of the characters and their positions on the document are determined. The resulting data is stored and subsequently collated to provide a sequence of data signals representing the characters in the correct order, e.g. for control of a printer. The system responds to editing marks for the insertion and deletion of characters. The document may be scanned by a row of vidicons, the area scanned by each vidicon covering several characters in each of several lines, and each area overlapping the neighbouring areas. The signals from the vidicons are digitized and fed to a store, a black-bit counter ensuring that only data in the region of the characters is fed to the store so that blank portions of the document are by-passed. The data from the store passes to circuits which, having detected the beginning of a character, determine its contours by contour tracing. The co-ordinates of the upper and lower left and right extremes are then determined. This being done the contours of the character are redetermined using large steps in the tracing. The resulting signals are compared with reference signals to identify character. If identification is not possible data relating to the character height and width is used additionally. If the character can still not be identified the contour tracing operation recurs this time using smaller steps. Failure to identify results in investigation of the signals from the co-ordinate determining circuits, and further failure in the comparison of a vector derived from the unknown character data with a set of reference vectors. If the character is still unrecognized a small area of the character field is investigated for the presence or absence of a part of the character and on the basis of this test the most likely identity of the character is determined. The signals identifying the character and its position on the document are stored prior to feeding a collating circuit which controls a printer or magnetic tape recorder. Editing.-Words to be deleted from the text on the document are characterized by a deletion line. Any character having such a line is identified as a deletion and is omitted from the collated signals, the space occupied in the original text by this character being omitted in the reproduced text. Additions to the text are placed above or below the relevent line of characters, and are characterized by an insertion symbol such as an oblique stroke. Such additions are automatically inserted in the reproduced text.

Abstract: 530,901. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd. July 5, 1939, No. 19574. Convention date, July 5, 1938. [Class 38 (iii)] Braking; travelling to predetermined limits.- An A.C. motor AM operating a crane or hoist is disconnected by opening of a switch VE when a final section of travel is entered, unless the controller st is returned to a slow-speed position in which a relay U is de-energized to close contacts by-passing the switch VE. The relay U is arranged to connect a motor EM, operating a brake for the main motor through hydraulic mechanism, to the main supply when energized in high speed positions of the controller st and to connect the motor EM to the secondary of the main motor in low speed positions. Thus the brake is raised in high speed positions of the controller until the switch VE is opened whereupon it is fully applied, and in low speed positions the degree of braking is inversely proportional to main motor speed whether the switch VE is opened,or not. Specifications 363,137, [Group XXIV], and 495,880 are referred to.
