Title: Pulse code generators
IPC: H04L9/22
Filed: 1972-07-03
Abstract: 1500900 Data transmission; ciphering SIEMENS AG 3 July 1972 [15 Nov 1971] 31124/72 Heading H4P A pulse code generator comprises a scanning device 2 for extracting data from a data carrier such  as a punched tape 1, a series-parallel converter 7 with parallel store sections 13-17 connected to the scanning device and individual pulse generators 30-35 controlled by data from a respective section 13-17. Data from the tape 1 is stored in a parallel mode in the store 7, the data being extracted from the tape by the scanning device 2 which may be mechanical or optical-electronic. A timing pulse train derived from a track 3 on the tape is supplied to a timer pulse circuit 8 whose output is supplied to counters 10', 10". The counter 10" produces stepping pulses to cause storage of data in the store 7 which is constructed to provide storage for an arbitrary period provided a continuous current supply is provided. Thus, in order to prevent erasure of the stored data in the event of failure of the current supply, an auxiliary supply 20 is provided and can be switched in. In order to ensure immediate erasure of the stored data in the event of any attempt at unauthorized access, a switch 21 is arranged to earth the store 7 upon such attempt being made. The output pulse train constituting the desired cypher is derived from generators 30-35. Data is read-out from the store 7 under the control of counter 10' triggered by an input pulse train 9 to a timer circuit 8. The output from the store 7 is supplied in the series mode on line 18 to an operations store 22 having a number of zones 24-29 each of which is associated with a respective generator 30-35. The latter produce shortperiod pulses which are synchronized and combined to form a long-period cypher signal pulse on line 37 from a logic circuit 36. Activation of store 7 is effected from a switch 41 which also supplies a blocking potential when recording has been carried out. Other, similar stores 7', 7" are provided and can be selectively switched in by means of a switch 40 to enable data from respective punched tapes to be stored successively in the respective stores. A cypher change can then easily be effected by changing the setting of switch 40. The setting-up part of the generator, namely the scanning device 2, stores 7, 7<SP>1</SP>, 7<SP>11</SP> and counters 10<SP>1</SP>, 10" can be constructed as a unit separate from the cypher unit constituted by the operations store and generators 24-29 so as to be capable of use detachment and to set up different cypher units.

Title: Improvements in the preparation and smelting of ores, roasterresidues, slags and the like
IPC: C22B1/08
Filed: 1922-11-14
Abstract: In the smelting of zinciferous ores or products containing iron in a blast, cupola or other furnace together with a chloride, coke, and limestone, the proportions of coke and limestone are made much less than those in the parent Specification, the iron not being reduced to the metallic state.  The zinc is volatilized in the form of a basic chloride and is collected in a wash liquor containing about 0.1-0.2 per cent of lime, the sludge of zinc oxide being then treated with carbon dioxide and the solid zinciferous product being then separated.  The materials to be treated, which may be ores, slags, &c., are not first desulphurized.  An example describes the treatment of a slag containing iron, zinc, manganese, and lead.  In the smelting operation metals such as lead and silver are recovered in the metallic state or as matte.

Title: Taper adjustment of cylindrical grinding machines
IPC: B23Q1/36
Filed: 1958-10-06
Abstract: 857,971. Grinding. JONES & SHIPMAN Ltd., A. A., and HOULDSWORTH, J. Sept. 16, 1959 [Oct. 6, 1958], No. 31828/58. Class 60. A method of adjusting the taper applied by a grinding wheel to a work-piece mounted between spaced supports comprises the application of a controlled force to one of the supports to distort it and thereby to set the orientation of the work-piece axis in a horizontal plane relatively to that of the grinding wheel. The tailstock of the machine comprises a main body 2 with an arm 11 arranged laterally of a support 10 which is designedly weaker than the arm 11. A ram 5 is hydraulically operated to move the support 10 in either direction and thus to incline the axis of the work slightly towards or away from that of the grinding wheel, or the support may be pre-stressed, the stressing being relieved when the work axis is shifted. In a modified form the ram 5 may be rounded at its outer end so that it bears only in an outward direction on the support 10. The taper adjustment may be automatically controlled by a valve 9 responsive to suitably amplified signals from gauges arranged to transmit the diameter differential between the opposite ends of the work-piece.

Title: Process for electrolysis
IPC: C25B1/34
Filed: 1953-11-23
Abstract: 781,287. Electrodialysis. HOOKER ELECTROCHEMICAL CO. Nov. 23, 1953 [Dec. 22, 1952], No. 32434/53. Class 41. A process for electrolytically decomposing electrolytic solutions comprises placing the solutions in cathode and anode compartments 4, 2 separated by a pair of permselective diaphragms 5, 6 of the same permselectivity, e.g. cationic, spaced to form an intermediate compartment 3, placing an electrolyte, e.g. water, at 17 in the compartment 3, passing electric current between electrodes 7, 12 through the diaphragms 5, 6 and electrolytes, reacting a chemical, e.g. carbon dioide, with products of electrolysis migrating through the compartment 3, recovering the reaction, products, and withdrawing the products of electrolysis. The added chemical, which may be introduced directly into the compartment 3 at 17 or introduced externally of the cell into an electrolyte which is circulated through the compartment 3, may be acidic where cationic diaphragms are being employed to react with hydroxyl ions which back-migrate from the catholyte, or basic where anionic diaphragms are employed to react with hydrogen ions which back-migrate from the anolyte. Examples of acidic chemicals are CO 2 , SO 2 , HCL, H 2 S, acetic acid and benzoic acid, while bases mentioned are alkali metal hydroxides or carbonates. In a specific embodiment brine enters at 9 and leaves at 10, chlorine leaving at 11, while water enters at 14, caustic leaves at 15 and hydrogen leaves at 16. Sodium carbonate solution is passed through compartment 3 on starting the cell in operation, and there. after circulates continuously from outlet 20 to inlet 17, water and carbon dioxide being supplied at 17. The carbon dioxide reacts with caustic formed in the compartment 3 to form sodium carbonate. The relative proportions of caustic and sodium carbonate so produced by the cell may be controlled by regulating the concentration of caustic in the catholyte, and hence the percent permselectivity of the cathode diaphragm. In one example in which brine was circulated through compartment 2, operating conditions were :-a voltage of 4.65, a temperature of 60‹ C. and a current density of 90 amps per square foot of diaphragm. Where SO 2  is added to compartment 3, sodium sulphite or bisulphite is produced. The diaphragms 5, 6 may be spaced around their peripheries by a gasket in which the inlet 17 and outlet 20 are formed, and at least one of the diaphragms may be reinforced by a grid. Electrolytes which may be decomposed are aqueous solutions of alkali and alkaline earth metal bromides, chlorides and sulphates, e.g. a diaphragm of opposite permselectivity to that of the two forming the compartment 3 may be inserted adjacent the corresponding electrode, and sodium sulphate solution introduced into the compartment between the pair of unlike diaphragms, as described in Specification 764,181 and a reactive chemical introduced, as previously described, into the compartment between the like diaphragms.
