Title: Method and apparatus for generating a binary image
IPC: G09G5/42
Filed: 1975-05-19
Abstract: 1504975 Memory systems INTERNATIONAL BUSINESS MACHINES CORP 19 May 1975 [10 June 1974] 21127/75 Heading G4A [Also in Division H4] Data representing image points of a field of graphical information to be displayed is assembled in binary words corresponding to respective rectangular areas of the image field, and the words are transferred to a store from which the binary data is read row by row to a raster display unit, e.g. a C.R.T. In the embodiment disclosed a general purpose computer supplies data representing line segments of the graphical information in the field. The data is converted to X, Y co-ordinate pairs corresponding to image points representing the line segments, Fig. 6A. Logic circuitry responds to each co-ordinate pair to record that pair as a bit within an area word that represents a rectangular area of the image. The position of the bit and the address of the word are defined by the X, Y pair. When an X, Y pair defining a different word occurs the word currently being assembled is transferred to a corresponding region of a random access store so that the new word can now be assembled When all the X, Y pairs have been dealt with the store contains an electrical analog of the field, and is organized on an area word basis, Fig. 8A. The stored data is now reorganized on a line word basis, Fig. 8B, in which each line word corresponds to part of a raster line of the display and comprises the bits of horizontally adjacent portions of the area words. The stored data is thus in a form in which it can be read row by row to the raster display.

Title: Improved photo-electric control, particularly for gas-light illumination
Filed: 1935-07-26
Abstract: 460,155. Clockwork-actuated valves. SOUTH METROPOLITAN GAS CO., HALL, W. H. B., and WHILLOCK, R. H. July 26, 1935, No. 21287. [Class 135] [Also in Groups XL, XXXVII, and XXXVIII] A photo-electric control, more particularly for turning a gas cock, ringing a bell, or operating a locking device, comprises a clockwork motor which is adapted to be started as a result of an increase above a predetermined lower limit of the amount of light falling upon a photo-electric cell, stops automatically when its function is at an end and is then ready to be re-started when the intensity of the illumination again varies in the opposite sense to the aforementioned increase or decrease beyond the respective predetermined limits. As shown in Fig. 1, a photo-electric cell a controls a relay b, the arm c of which moves between, contacts d, e. An electromagnet f, which controls the actuation of a clockwork motor contained in a casing k for driving the gas control cock l, Fig. 2, is included in two circuits, one from battery g through contact d and switch contact h and the other from the battery through contact e and switch contact i. As shown in Fig. 2, the clockwork is arrested by contact of a rotary stop m with a projection on one arm of a double armed lever n which is urged by spring o so that its other arm n<1> engages a recess in the periphery of a disc p on the cock l. This disc has two bosses e, r of insulating material each adapted, when the disc rotates, to lift contacts h, i so that they touch contacts h<1>, i<1> respectively. As shown, boss r is in position to close contact h, h<1>. In this position, the room is illuminated by gas, the cock l being fully open. When the daylight intensity improves, the cell a moves arm c on to contact d. Contact h being already closed, magnet f is energized and armature s is attracted to lift lever n out of engagement with stop m and arm n<1> out of recess in disc p. The clockwork now starts and arm n<1> rides on periphery of the disc. At the same time contact h is opened by the onward movement of boss r so that circuit of magnet f is broken. The disc continues to turn cock l to cut off the gas supply until arm n<1> slips into the next recess whereupon the projection on lever n stands in the way of stop m. In this new angular position of disc p, boss q is beneath contact i and the circuit containing contact e is ready for energizing magnet f when the intensity of the daylight again determines the movement of arm c on to that contact. This next operation of the device turns the cook l into the " on " position and gaslight illumination is again provided.

Abstract: 286,745. White, A. E., (Allen, S. G.). Aug. 30, 1926. Blast, composition of; purifying and refining. - In a Bessemer process for making steel, more especially for use with non-Bessemer pig iron, the net blow heat required to Bessemerize a charge of given characteristics is determined, and the amount of oxygen in the oxygenated blast is so proportioned to the amount of inert gases as to give the required net blow heat. The net blow heat is defined as the gross amount of heat developed by oxidation in the molten charge by the oxygen of the blast employed less the amount of heat absorbed by the blast itself in attaining the temperature of reaction. In an example it is stated that to treat an iron containing 1 per cent of phosphorus, the blast contains 38 per cent of oxygen.

Abstract: 1,224,395. Making tubular film of thermoplastic synthetic resin. MITSUBISHI YUKA K.K. 9 May, 1968 [9 May, 1967], No. 22003/68. Heading B5B. In the manufacture of tubular film of thermoplastic synthetic polymeric material by melt extruding the material downwards through an annular orifice simultaneously expanding the film radially to a predetermined degree by introducing pressurized air into the interior of the film, drawing the inflated tubular film thereby formed through a bath of cooling liquid below the extrusion die, and thereafter through the nip of a pair of nip rolls, the film during its passage through the bath of cooling liquid is caused to travel along mutually opposed flat apertured surfaces immersed in the bath. The aperture of the surfaces communicate with suction means and the film is folded to a flat form and cooled, the suction applied to the apertures holding the film against the surfaces and drawing cooling liquid between the film and the surfaces and into the apertures. As shown in Fig. 1, a tubular film f is melt extruded downwards through the annular orifice of a die 1 and is drawn by the nip rolls 14 into a bath of a cooling liquid 3 in which are immersed two suction boxes 5 facing one another. The opposed flat surfaces 6 of boxes 5 are provided with apertures and may, for example, be fine mesh wire screens through which the cooling liquid 3 can be sucked into chambers 7 within the boxes 5 by means of suction tubes 9 communicating with the chambers 7 and leading to a circulating pump 8 which returns the liquid through duet 11 to the lower part of the tank 2. Duct 11 may include means for cooling the liquid. The portion of the film between the die and the surface of the cooling bath is expanded radially to a predetermined degree in the usual manner by the introduction of air at a constant controlled pressure into the interior of the film. The flattened film after leaving the nip rolls 14 is drawn over a guide roll 15 and between rolls 16 to a wind-up roll 17 outside the cooling tank. As shown in Fig. 1 the mutually opposed surfaces 6 of the suction boxes converge in the direction of travel of the film.
