Abstract: 1332337 Gas separation; sulphur content reduction SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 15 Dec 1970 [21 Sept 1970]. 59501/70 Heading C1A The total sulphur content of Claus off gases containing H 2 S, SO 2  and also CS 2  and/or COS is reduced by (1) passing the off gases, together with H 2  and/or CO containing gas at a temperature above 175‹ C. over a Group VI and/or Group VIII metal catalyst supported on an inorganic oxide; (2) subsequently or simultaneously contacting the off gases with a solid catalyst to convert CS 2  and/or COS to H 2 S; (3) removing H 2 S by contacting with an absorbent or adsorbent. The H 2  and/or CO containing gas, e.g. town gas, water gas, synthesis gas, H 2 -rich off-gases, preferably contains at least 20 vol. per cent of H 2  and is used in an amount such that the H 2  : SO 2  ratio in the gas mixture is 3 to 15 : 1, The reduction catalyst (a Group VI and/or VIII metal) may be used in oxidic or sulphided form. Sulphiding may be effected by an H 2 /H 2 S mixture or in situ by means of the Claus off-gases. Specified CS 2  and/or COS conversion catalysts are alumina, bauxite, activated clay, aluminium phosphate, thoria and MgCl 2 . The alumina may be impregnated with alkali metal phosphate. The two catalysts may be used at substantially the same temperature. Simultaneous contacting of the Claus off-gases with the two catalysts may be carried out using a mixture of catalysts in a fixed acceptor bed, or by arranging two or more separate beds of single catalysts on a single reactor. The H 2 S absorbent may be solid, e.g. carbon, metal oxides or liquid e.g. alkanolamines, amines, ammonia, metal carbonate solutions. The liquid absorbent may contain an oxidant and/or a catalyst (many specified) to form elemental S. In an example, Claus off-gas mixed with H 2  is passed over sulphided Co/Mo/Al 2 O 3  at 222‹ C., then over activated alumina at 223‹ C. and finally over active carbon at 130‹ C.

Title: Improvements in and relating to Sheet Locating Arrangements for Copying Machines.
IPC: G03G15/043
Filed: 1968-12-16
Abstract: 1,191,400. Feeding sheets; copying machines. RICOH K.K. 16 Dec., 1968 [19 Dec., 1967], No. 59619/68. Heading B8R. An arrangement for locating sheets in a copying machine comprises a table supporting an original sheet, a table supporting a stack of copy sheets, an adjustable member engaging one side of the stack, and an index member mounted on the original sheet table and coupled for movement with the adjustable member either to provide an indication of the copy sheet size, or to assist in aligning the original relative to a copy sheet. Fig. 1 illustrates a machine in which an original sheet is fed from table 1 by rollers 3, 4 to an actuator 7 for a roller 8 separating copy sheets from a stack supported on table 11. Rollers 13, 14 are initially spaced apart, and the original and copy sheet are aligned at their leading edges by movable stop 15; the rollars 13, 14 then move together, and feed the sheets to exposure station 16. In one embodiment, Fig. 2, the adjustable and index members are each formed by upright plates 9, 25 engaging an edge of the stack and a corresponding edge of the original, respectively, and are coupled for movement together by a wire and pulley arrangement 31-34, acting on rods 24, 26 integral with the plates and sliding in lateral slots in the tables 1, 11. In a second embodiment, Fig. 3 (not shown), the plate (25) is replaced by a slide (103) provided with an indicator scale (105) so that by aligning the side edge of an original on table 1 with the datum of the scale, it will be aligned with the copy sheets. In Fig. 4 (not shown), the wire and pulley arrangement is replaced by pistons and cylinders. Delivering sheets.-After exposure at station 16, Fig. 1, copy sheet and original are separated automatically at 17, the copy sheet is developed at 18, and the original is either removed at outlet 21, or is recirculated for further copies by gate 22.

Title: Magnetic recording and or reproducing apparatus
IPC: G11B5/58
Filed: 1970-12-17
Abstract: 1317316 Automatic control of contact pressure in magnetic record apparatus INTERNATIONAL BUSINESS MACHINES CORP 17 Dec 1970 [31 Dec 1969] 59909/70 Heading G3R In a magnetic recording and/or reproducing apparatus the contact pressure between a magnetic transducer 12 and the undulating surface of a magnetic medium 10 (e.g. an annular disc) which moves relative thereto, is automatically maintained substantially constant at a predetermined value. An actuator 30 is carried by a gliding platform 21 and a rigid arm 22 a pole tip of the magnetic transducer being held in contact with the recording surface 11. The bottom surface of the platform is supported clear of the surface 11 by air bearing action produced by the action of air carried by the rotating disc, on the said bottom surface. The actuator 30 may comprise a magneto-strictive crystal or a Piezo-electric crystal. A pressure transducer 40 (e.g. a strain gauge having solid state components) produces an output signal in response to force applied to its surface contacting the magnetic transducer 12. The amplified signal from the pressure transducer is compared with a reference value signal, in a comparator 50 which produces an error signal output in dependence upon any difference therebetween. This error signal is amplified in a driver 57 and applied to the force actuator 30 which expands or contracts causing a corresponding displacement of the actuator surface in contact with the pressure transducer 40 and a like displacement of the surface contacting the magnetic transducer. Thereby contact pressure between the magnetic transducer 12 and the medium surface is maintained substantially constant.
Patent GB-735410-A (GB)
Abstract: 735,410. Electric indicating systems. DAIMLER-BENZ AKT.-GES. Sept. 16, 1953 [Sept. 16, 1952], No. 25624/53. Class 40 (1). To measure vibrations of a body, e.g. a machine, electrically, a detector 1 is adapted to be held manually with its feeler pin 6 pressed against the body under test. The pin 6 is biased outwardly by a spring 8 which is stressed when the feeler is pressed against the test body until a pointer 11 indicates that the pin 6 has reached a central position. In this position the non- magnetic central portion 5 of the pin 6 lies substantially centrally within a coil, or, as shown, two axially disposed coils 2, 3 connected in the arms of a bridge, Fig. 3, energized from a high-frequency oscillator T. The H.F. output of the bridge is modulated in accordance with the vibrations of the test body, amplified at V, demodulated in a phase sensitive rectifier G and passed through a filter S to an oscillograph O or other indicator or recorder. The frequency range of the detector may be extended downwardly by increasing the inertia of the detector handle, e.g. by screwing additional mass thereto, and extended upwardly by reducing the mass of the feeler pin or by using a more powerful spring 8. Variable condensers may be used in lieu of coils 2, 3.
