Title: Saw tooth generators
IPC: H03K4/71
Filed: 1971-12-11
Abstract: 1372856 Vertical deflection circuits MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 11 Dec 1971 57689/71 Heading H3T A vertical deflection circuit of the type comprising an integrator reset by a switching circuit and in which the switching circuit is operated by a narrow pulse from an oscillator synchronized by synchronizing pulses, positive feedback in the deflection circuit provides a pulse which maintains the switching circuit operated throughout the flyback period so that jitter due to variation in pulse width from the oscillator is avoided. The Figure shows a Miller integrator comprising transistors 55-59 and a feedback capacitance 63, 64, the integrator being charged through a resistor 73 and discharged through a transistor 53 in response to a synchronizing pulse received from an oscillator 52 via an isolating diode 54. Lineaity is improved by resistors 66 and 67 and a capacitor 68 prevents oscillation. A positive feedback pulse derived from the differentiating and attenuating circuit 41-44 maintains the switching transistor 5 conductive throughout the flyback. A capacitor 62 tunes the deflection coils.

Title: Treatment of gases
IPC: B01D53/50
Filed: 1971-12-14
Abstract: 1366719 Gas separation; calcium sulphate MITSUBISHI JUKOGYO KK 14 Dec 1971 [29 Dec 1970] 58117/71 Heading C1A Sulphur dioxide is removed from waste gas streams by (a) washing the gas with a suspension of calcium hydroxide or calcium carbonate having a low pH in a first absorbing unit; (b) passing the washed gas from the first absorber to a second absorbing unit where it is washed with a suspension of calcium hydroxide or calcium carbonate having a high pH; (c) periodically reversing the flow of gas and absorbent liquid between the two absorber units so that in the second unit fresh gas contacts low pH absorbent and in the first unit washed gas contacts high pH absorbent. Any dust present in the gas stream may be removed prior to entry into the first absorbing tower by a spray of circulating water. In the first absorbing tower calcium sulphite is formed, part of which may be oxidized by any oxygen present in the flue gas to calcium sulphate. Since the amount of calcium sulphate formed is small and the oxidation period is short large crystals cannot grow but a small quantity of gypsum scale attaches itself to the inner walls of the first tower. No calcium sulphite is deposited in the first tower since it is solubilized by the absorbing liquid. In the second tower soft scale consisting essentially of calcium sulphite and calcium carbonate is deposited. On reversing the flow of liquid and gas streams, the calcium carbonate in the soft scale in the second tower is converted into calcium sulphite which is dissolved in the absorbing liquid. The absorbing liquid after leaving both towers is led to an oxidizing tower where calcium sulphite is oxidized to calcium sulphate.

Title: Apparatus for breaking up the particles and lumps of sand particles for cooling
IPC: B22C5/08
Filed: 1979-07-16
Abstract: In order to cool (foundry) sand, it is carried into a housing 14 by conveyor 2. Rotating disintegrators 10 and 12 cause particles of sand to be projected at an upper endless conveyor 30 which receives the sand and projects it through a screen 44 typically formed of vertically disposed, spaced-apart, piano wires under tension. Liquid nitrogen is sprayed at the particulate material after it has passed through the screen 44 by means of a spray header 46 having spray nozzles 48. Nitrogen vapour is extracted from the apparatus by means of a fan 52 located in a passage 50 in communication with a vapour extraction chamber 22 which, in turn, communicates with a chamber 20 in which the conveyor 30, screen 44 and spray header 46 are located. The action of projecting the sand at the screen causes lumps of it to be broken up and thereby makes possible more effective cooling of the sand by the liquid nitrogen. If the liquid nitrogen spray header 46 is omitted the apparatus may simply be used to break-up lumps of the sand. <IMAGE>

Title: Electron beam lithography
IPC: G03F7/20
Filed: 1980-01-18
Abstract: In electron beam lithography apparatus a substrate, on which an exposure pattern is to be produced, is exposed to a plurality of electron beams. In a double beam arrangement one beam is capable of the highest resolution required and has a necessarily low writing speed. The other beam is relatively coarse in beam width but carries a higher current and has a much higher writing speed. Single-pole magnetic lens focusing is used with close angular spacing between the beams. Scanning of the pattern is programmed for economy of time so that the beams produce complementary portions of the pattern, the fine beam defining for example the edges of a structure while the coarse beam scans the area bounded by the edges. Scanning may be simultaneous or sequential. Selection of the relative values of beam potential and the use of energy selective detectors enable the two scanned regions to be imaged.
