Title: A method of dewatering cellulose pulp
IPC: D21F1/66
Filed: 1964-10-02
Abstract: 1,033,048. Drying cellulose pulp. SVENSKA CELLULOSA A.B. Oct. 2, 1964 [Oct. 5, 1963], No. 40175/64. Heading F4G. [Also in Division D2] Cellulose pulp is dewatered by passing at least 1% dry pulp to a press where it is dewatered to a dry content of 40-60%, the pressed pulp is then fluffed, and the fluffed pulp is conveyed and dried by hot gas until the average dry content of the pulp amounts to 90-95%. As described a sulphite-, a sulphate- or a semi-chemical pulp passes from vat 1 via rotary drum filter 3, feed screw 7, and vat 10 to press 13, there being a concentration controlling device, and a meter 14 controlling pump 11 to ensure a constant flow rate. The pulp web from press 4 is shredded by roll 5 and conveyed, optionally by a conveyer, to vertical tube 16, where hot air from tube 17 passes the pulp to separator 18 and fluffing rolls 19. The pulp is then conveyed by hot air through drying towers 24, 34 and separators 26, 36, 42. A heat exchanger 29, an oil burner 30, and cooling air from valve 39 are provided. The dried pulp is pressed into sheets and passed to baling press 46. The amount of fibrous bundles is reduced in the dried pulp by having a low chlorine number-e.g. for unbleached sulphate pulp a value of 2-10-, by adding SO 2 -water through conduit 9 so that an aqueous solution of the stored dried pulp would have a pH 'value of 5-7, by keeping the temperature of the pulp in press 4 at 60-100 C., by ensuring that the pulp is evenly distributed in press 4 by the use of pulp flow controlling means or by vibration, and/or by ensuring that the pulp is evenly dried. The latter may be accomplished by a final step of drying in the apparatus of Specification 576,056, of drying by dielectric heating or radiation, or of passing over the pulp on a perforated belt a stream of conditioned air.

Title: Sheet processing machines
IPC: B65H7/04
Filed: 1972-08-31
Abstract: 1363544 Feeding sheets POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 31 Aug 1972 40337/72 Heading B8R Sheets are normally separated one at a time from the top of a pile, and means are provided to sense the thickness of separated sheet material (if any) so as to detect if more or less than one sheet has been separated, and if so rendering the processing machine inoperative during the time a normally fed sheet would pass therethrough, and in the case of more than one sheet removing the multiple sheet from the flow of the machine. Preferably, before the latter step, the multiple sheet is returned to the pile and one or more further attempts made to separate a single sheet. After each separation action, any sheet or sheets separated are gripped between an abutment 4, Fig. 2, and a gripper 5 formed by one end of a two-armed lever 6 oscillated after each separation action by a pneumatic piston 13<SP>1</SP>. The uppermost position of the gripper 5 is detected by a transducer 8 sensing the position of a scanning finger 10. The position of the transducer is adjusted by a screw 16 according to normal sheet thickness. Warning lights 11, 12 may be illuminated to show abnormal condition. In another form, Fig. 3, the surface 24 on a camoperated lever 18 presses the sheet or sheets 25 against a scanning pin 26 of a transducer 27 to raise the pin if there is more than one sheet, while the surface 24 touches an electric contact to produce a signal if there is no sheet. In another form, Fig. 5, a suction separator nozzle 33 includes a portion 32 movable relative to the main nozzle body when suction is built up on picking up a sheet, the relative movement moving a scanning finger 10 with respect to a transducer 8. With no sheet, the portion 32 does not rise. With one or more sheets, the portion rises, but with more than one sheet the weight of the sheets causes the rise to be less than normal.

Title: Improvements in or relating to magnet core switches
IPC: H03K17/81
Filed: 1963-10-15
Abstract: 1,006,027. Selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 15, 1963 [Oct. 18, 1962], No. 40649/63. Heading G4H. [Also in Division H3] A magnetic core switch comprises a plurality of magnetic cores having energizing windings, each winding on each core being connected in series with an energizing winding on each other core, means for energizing selected series arrangements of windings, and means for supplying a compensating current to a further series arrangement of windings each time a current is supplied to a series of energizing windings, so that the magnetic effects of the energizing and compensating currents compensate each other in all cores except one. A storage address selection arrangement for use with a matrix having row or column conductors 17 to 20 consists of four cores 1 to 4 with energizing windings 5 to 8 controlled by transistors 9 to 12, the windings threading the cores in the " + " or " - " direction, as in Fig. 2a. Compensating winding 21 threads all the cores in the " - " direction. To generate a write pulse in load 20 the control electrodes of transistors 9, 10 and 11, and 22, are pulsed. The selected core 4 then receives a resultant energization by two energizing currents, while the unselected cores receive zero resultant energization. To generate a read pulse in load 20, transistors 12 and 22 are made conductive so that core 4 receives two energizing currents switching it in the negative sense, while the remaining cores are unenergized. The system may be enlarged to accommodate 4<SP>n</SP> cores by development as in Figs. 3a and 3b. Each core is threaded by 4<SP>n</SP> + 1 windings, the writing and reading currents have 4n a relative strength of - and the compensating 2 current has a relative strength 2(<SP>n-1</SP>), which is   1/2n times the total current flowing. It is shown that in a system using 64 or more cores the currents are distributed sufficiently to be handled by a single transistor in each line. Arrangements with 2 x 4<SP>n</SP> cores are derived as shown in Figs. 5a and 5b' As shown, the compensating winding is omitted from the lower half of the system. The compensating current supplied to the upper half is doubled.

Title: Improvements in ribbon feeding devices
IPC: B41J35/14
Filed: 1958-12-17
Abstract: 879,472. Ink-ribbon mechanisms. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 17, 1958 [Dec. 20, 1957], No. 40735/58. Class 100(4) Automatic reversal arrangements. A ribbon feeding device comprises a pair of flangeless spools, a rocking pawl 58 actuated from a cam follower 54 and a powered cam 20, and which rocks in one plane to advance one ratchet wheel 48L until one spool is exhausted, whereupon toggle means pivot the pawl, about an axis 90 degrees to rocking movement, so that the pawl acts in a second plane to engage the other ratchet wheel 48R, and reverse the direction of ribbon feed. The action of the toggle means is initiated upon a button on the end of the ribbon, pivoting a guide 30R about pin 32R. This allows right hand flange 40R of a reversing member 38 to move clockwise about the point where the left-hand flange 40L engages the other guide 30L. The lower end of the reversing member has outer arms 72L, 72R, and a central arm 74 which is now in the path of the pawl 58. Rocking movement of pawl 58 in direction of arrow causes arm 72R to shift detent toggle 66 from ratchet 48L to 48R after which a spring 70 pivots the pawl 58 into a plane to engage the ratchet 48R. Detachable holders and spool construction. The spools have no flanges so they may be mounted close together in a removable cartridge 18 of transparent styrene fitted on to a carriage which may move along the printing line as described in Specification 873,920.

Title: Production of hydrogen
IPC: H01M8/065
Filed: 1973-08-30
Abstract: 1420048 Hydrogen production SIEMENS AG 30 Aug 1973 [13 Sept 1972] 40969/73 Heading C1A Hydrogen is made by (a) forming a particulate mixture of magnesium, or magnesium and aluminium, and at least one cobalt oxide, and (b) reacting the particulate mixture with water in the presence of at least one water-soluble chloride. The ratio by weight of magnesium to aluminium in the mixture may be from 7 : 1 to 2 : 6 especially from 5 : 3 to 3 : 5, and the amount of cobalt oxide or oxides used in the mixture may be from 0À5 to 5% by weight, based on the weight of magnesium, or on the total weight of magnesium and aluminium; tricobalt tetroxide CO 3 O 4  is preferred. The amount of chloride may be from 5 to 200% by weight, on the above basis; sodium chloride is preferred but potassium or magnesium chloride may be used. An aqueous chloride solution, e.g. sea-water, may be used, or the chloride or chlorides may be dissolved in the water before reaction with the mixture. The mixture may contain a filler, suitably an inorganic salt, to prevent agglomeration of the metal particles. Preferably, a cobalt oxide and water-soluble chloride are added to powdered magnesium and the resulting mixture introduced into water. Alternatively, the chloride may be dissolved in water and the mixture of magnesium and a cobalt oxide introduced into the resulting aqueous solution. In apparatus as shown, a mixture of metal powder (magnesium or a magnesium/aluminium mixture) and cobalt oxide is introduced into storage vessel 11, and the reaction vessel 10 partly filled with aqueous sodium chloride solution or with sea-water, or, where the reaction vessel is, as shown, in the form of a tube open at its lower end, partly immersed in the corresponding liquid. Screw feeder 13 is driven by motor 14, arranged with the contact manometer 16 in an electrical circuit in which the motor is switched on or off when the working pressure of hydrogen falls below or exceeds a predetermined limit. Thus the evolution of hydrogen is triggered or brought to a standstill. As reaction proceeds, metal hydroxide formed sinks downwards and can escape through the lower end of the tube, which is of such length that no unused metal leaves; the immersed length of the tubular reaction vessel is such that the hydrogen pressure obtained is compensated by the column of water corresponding to the immersed length so that hydrogen cannot escape downwards through the reaction vessel.

Abstract: 1,198,671. Gas manufacture. H. F. A. TOPSOE. 12 Sept., 1967 [12 Sept., 1966], No. 41534/67. Heading C5E. A gas, exchangeable with natural gas, is made by reacting a hydrocarbon feed in the gas phase with steam at 200-500‹ C. and a pressure of 1-200 kg./cm.<SP>2</SP> gauge in the presence of a catalyst comprising Group VIII metals or copper and of an activator. Suitable activators are ammonia, hydrazine, hydrazines substituted by alkyl groups having 1-10 carbon atoms, and aliphatic amines having 1-10 carbon atoms and are used in amounts of 0À01 to 3% by weight, calculated as ammonia, of the hydrocarbon feedstock. The activator can be added continuously or intermittently into the reaction mixture either immediately before the latter is introduced into the reforming reactor or prior to a hydrodesulphurization of the feed. Ammonia can be added to the feed-water for steam reforming and the ammonia-containing water separated from the product gas can be recycled to the feed-water. Suitable feedstocks are propane, butane and light distillates boiling from 40-250‹ C. Hydrogen, oxygen, carbon monoxide, carbon dioxide and lower alkanols can be included in the feed. The O: C ratio in the feed is between 0À3 and 30 and between 0À8 and 1À8 if the reaction is to be autothermic. The product gas, after removal of carbon oxides and excess steam, consists almost entirely of methane and hydrogen. Suitable catalysts are made by impregnating a porous carrier, e.g. magnesium aluminium spinel with Ni, Co, Fe or Cu or by incorporating the catalytic metal during formation of the spinel by coprecipitation; oxides of potassium and calcium can be included in the catalysts as promoters.
