Title: A registering and printing mechanism for meters
IPC: G01R11/64
Filed: 1955-03-02
Abstract: 796,816. Counting-apparatus. LANDIS & GYR AKT.-GES. March 2, 1955 [March 2, 1954], No. 6220/55. Class 106 (1). A device for automatically recording meter values on a record strip comprises at least two identical printing mechanisms operating in line across the strip and means for separating the strip into as many bands as there are printing mechanisms, or for weakening the strip longitudinally to facilitate such separation, whereby in use identical information is recorded on each of the bands. The printing wheels 11, Fig. 1, of two associated counters, A, B, are mounted on a common shaft 13 and are driven through transfer pinions 10 on a shaft 12 from a spring 6- continuously tensioned by a motor 4. The drive from the spring 6 to the shaft 12 includes a differential gear 7, 8, 15, 16 and the gearing 14 which is also connected through gearing 18 to a totalizer 19. The gear 8 of the differential is fixed to a control shaft 9. A mechanism 20, 21 controls the planet gear carrier 16 to allow stepwise movement of the counters A, B in accordance with the quantity being measured. A record strip 1 passes from a roller 2 between the printing hammers 28 and the wheels 11. The hammers 28 and a knife 37, Fig. 2, are mounted on a shaft 27 which is controlled through a lever 26, Fig. 1, by a cam 24 on the shaft 9. A transverse blade 31 in front of the wheels 11 of the counter B is controlled jointly by a cam 25 on the shaft 9 and a latch mechanism 33, 32, 29 operated by an electromagnet 34. The shaft 9 also actuates the record strip feeding mechanism 36 through a crank 35. The arrangement is such that the counters A, B step forward under the control of the mechanism 20, 21 and at intervals the mechanism 23, 22 is operated to allow the shaft 9 one complete revolution. The cam 24 actuates the lever 26 to effect operation of the hammers 28 and the knife 37 which divides the strip into two longitudinal. strips. A gear segment 17 on the shaft 9 then rotates the shaft 13 to effect zeroizing of the counters A, B and the record strip feed mechanism 36 is operated. The latch 33, 32, 29 locks the knife 31 against operation when the lever 29 is freed by rotation of the cam 25. At larger intervals when the shaft 9 is released for its revolution the electromagnet 34 is at the same time energized to release the latch 33, 32, 29 so that the cam 25 releases the knife 31 for operation by the spring 30, thereby dividing the right-hand strip into portions. The left-hand strip passes round the roller 3 and the right-hand strip portions pass into a trough 42 in the casing 38 from which they can be removed through the opening 41, Fig. 2.

Title: Improvements in and relating to electrophotographic material
IPC: G03G5/14
Filed: 1964-02-14
Abstract: 1,062,092. Coated paper. AZOPLATE CORPORATION and RIEGEL PAPER CORPORATION. Feb. 14, 1964 [Feb. 15, 1963], No. 6320/64. Heading B2E. [Also in Divisions D1 and H1] A coated material consists of a duplex paper base bearing a conductive film resistant to penetration by water and organic solvents and, optionally, on top of this film a carbon-filled clay coating. The lower layer of the duplex paper may be impregnated with a conductive resin while the upper layer is filled with carbon black or powdered metals such as copper and aluminium. The conductive film consists of a filling of carbon-black, copper or aluminium in a binder such as plasticised nitrocellulose (e.g. using dibutyl phthalate), an oil-modified alkyd resin, an epoxy resin, or polyvinyl chloride. The carbon-filled clay coating may be based on a conventional starch-clay or casein-clay mixture optionally containing 10-20 wt. per cent. of a butadiene-styrene latex. In the example of Fig. 2 cylinder machines 17, 18 are respectively fed with a carbon-bearing pulp furnish of predominantly cellulosic fibres and with a carbon-free pulp furnish of cellulosic fibres are merged while wet and passed through drier 19. (A single cylinder machine and a fourdrinier machine may instead be used). The duplex web may be machine calendered and/or supercalendered. The conductive film is applied by gravure applicator 20 and smoothed by bar 21 before being passed through a curing oven 22. The process may be stopped here or, as shown, may be continued by the application by wire or blade coater 23 of a solvent carried mixture of zinc oxide and silicone resin. The material, after its passage through curing oven 24, forms an electrophotographic material having a photoconductive surface layer.
Patent GB-900376-A (GB)
Title: A process for the oxidation of ethylene to ethylene oxide
Filed: 1961-02-21
Abstract: Ethylene is oxidised to ethylene oxide at an elevated temperature in the presence of a silver catalyst by a molecular oxygen-containing gas obtained from air by distillation and which has a molar concentration of oxygen of at least 85% and in which the proportion of argon has been reduced substantially with respect to the proportion normally present.  Preferably the concentrations of nitrogen and argon in the oxygen-containing gas are such that the ratio <FORM:0900376/IV (b)/1> , in which A is the number of moles of argon and N2 the number of moles of nitrogen in the mixture, is not greater than 0.6.  These preferred oxygen-containing mixtures may for instance, be obtained by separating from air a fraction with a high oxygen content having a value for the ratio <FORM:0900376/IV (b)/2> in excess of 0.6 and diluting the mixture with air until the ratio has a value below 0.6, preferably about 0.1, while keeping the molar proportion of oxygen above 85%.

Filed: 1973-02-09
Abstract: 1401718 Treatment of nickeliferous oxide ores INTERNATIONAL NICKEL CO OF CANADA Ltd 9 Feb 1973 [9 Feb 1972] 6402/73 Heading C7D Nickeliferous oxide materials (e.g. nickeliferous lateritic ores and roasted nickeliferous sulphidic ores) are pre-heated to a temperature above 850C and mixed with at least one chloride of an alkali or alkaline earth metal or iron and maintained at a temperature between 900C and 1100C by direct heating in an atmosphere reducing to nickel chloride but non-reducing to ferrous chloride (e.g. a hydrogen containing atmosphere having a reducing potential equivalent to a CO:CO 2  volume ratio between 1:2 and 4:1) to produce metallized particles containing most of the nickel and of any cobalt present which are then recovered. Particulate carbonaceous material may be added to the pre-heated material which may be partially reduced as a result of the pre-heating process. The chloride and/or carbonaceous material added may be in the dehydrated form and the mixture of oxidic material, chloride and carbonaceous material may be directly heated to 900-1100C by combustion of fuel and pre-heated free oxygen containing gas or oxygen enriched air. The process may be carried out in a multi hearth furnace or by pre-heating nickeliferous oxidic material using burner 24 in rotary furnace A mixing with controlled amounts of chloride and carbonaceous material in housing C and heating the mixture in rotary furnace B at a reducing temperature by combustion of fuel and free oxygen containing gas flowing co-currently from burner 29. The reduced solid material and gases may be removed by valve 32 and flue damper 31 respectively and the solid material may be cooled under non-oxidizing conditions and the nickel values separated therefrom by magnetic separation or by flotation. The gases may be cleaned in a wet scrubber the solution of which is neutralized with a base (e.g. limestone) or high iron ore or reduced nickeliferous oxidic material and the chlorides so produced recycled.

Patent GB-385139-A (GB)
Title: Manufacture of condensation products
IPC: C09D101/18
Filed: 1932-03-03
Abstract: Condensation products, which are probably acetals, are manufactured by causing a cyclic ketone to act upon a polyhydric alcohol containing at least six carbon atoms, other than a polyvinyl alcohol, in the presence of an acid or acid reacting substance.  Alternatively an ester of the polyhydric alcohol may be employed provided that the conditions are such that the alcohol is intermediately formed.  As polyhydric alcohols may be employed sugars, e.g. dextrose, a monosaccharide, a disaccharide or a polysaccharide, other carbohydrates and derivatives thereof, e.g. starch, dextrine and the derivatives, hydrogenation products and alkylation products thereof, sorbitol and mannitol.  The products may be used in the lacquer industry, e.g. as softening agents for cellulose lacquers.  Examples describe the condensation in the presence of sulphuric acid of (1) dextrose and cyclohexanone; (2) cane sugar and 2-methylcyclohexanone; (3) mannitol and cyclohexanone; (4) sorbitol and 2-methylcyclohexanone; (5) cane sugar and 2-methylcyclohexanone in methyl alcoholic solution; (6) fructose and cyclohexanone; (7) dimethoxytrioxyhexane (obtainable by reduction of methyl cellulose) and p-chlorocyclohexanone.

The temperature of the plasma contacting surface of a MHD generator electrode is maintained substantially constant by providing longitudinal cooling channels whose distance from the surface increases in the direction of plasma flow. In the electrode shown, wedgeshaped members 21, 22 are secured, by hard surfacing, to body 20 of the electrode so that cooling channel 11 in the body lies at progressively increased distances from surface 10 in the direction of plasma flow 9. The size of the wedge-shaped members is determined experimentally by comparing the temperatures at the ends of the electrodes using thermo couples 18. In a modification, the body of the electrode comprises opposed wedge-shaped members forming a cooling channel at the contacting faces, with a layer of corrosionresistant material hard surfaced on to the free face of the inner wedge, Fig. 4 (not shown). In a further modification, electrode blocks each having a cooling channel are hard surfaced with different sized blocks of corrosion resistant material and mounted in a stack with adjacent blocks separated by refractory cement to provide a segmented electrode construction, Fig. 5 (not shown). In this last construction the transverse cooling channel in each block is spaced from the surface of the block by a distance which reduces in the direction of coolant flow to maintain constant temperature transversely across the segment face.
