Title: Data processing systems
IPC: G06F9/26
Filed: 1973-01-17
Abstract: 1405322 Microprogrammed data processing system SIEMENS AG 17 Jan 1973 [1 Feb 1972] 2402/73 Heading G4A A microprogram controlled processing system includes a first microprogram store containing a series of microinstructions and a mask, an address register for accessing the first store, and a second microprogram store accessed under control of a macrocommand to produce microinstruction parts which replace parts of a microinstruction read from the first store under control of the mask. Store 11 contains microinstructions common to all macroinstructions and store 13 contains parts of words to be used to modify a microinstruction from store 11 to convert the microinstruction to a microinstruction specific to a particular macroinstruction. Store 13 is addressed by the current macroinstruction and the data read out replaces part of the data read from store 11 selected under the control of a mask also read from store 11. In the embodiment of Fig. 3 a " read out macroinstruction " microinstruction is accessed from store 11 by an address table 17 via switch 18 path a. The next macroinstruction is thus loaded into register 15. Store 11 is sequenced via incrementer 21, switch 18 path e, or by jump addresses forming part of an instruction read from store 11 and fed to register 12 via switch 18 path d. The macroinstruction in register 15 addresses store 13 part of whose output via switch 18 paths b and c may select the first microinstruction in a sequence from store 11, e.g. an operand fetch sequence. Parts of the instructions read from store 11 are replaced by the output of store 13 under the control of the mask M read from store 11. A gate assembly is described for switch 18 with a feedback from output to input to enable the switch to function as a latch. The stores 11 and 13 may be read only program stores, store 13 containing modifying parts for the output of store 11, and the addresses in store 11 of various microinstruction sequences, e.g. read out macroinstruction, operand fetch etc. sequences.

Abstract: 1,176,892. Etching. FMC CORP. 17 Jan., 1968 [17 Feb., 1967], No. 2458/68. Heading B6J. An etching solution containing hydrogen peroxide and sulphuric acid, which has been used to dissolve copper and which contains residual hydrogen peroxide values is reactivated by cooling to crystallize copper sulphate values therefrom without substantially reducing the amount of residual hydrogen peroxide and separating the crystallized material from the remaining solution. Cooling may be to temperatures from - 8‹ to +20‹ C. The etching solution may contain ammonium sulphate in which case cooling may be to temperatures from - 2‹ to + 20‹ C. The solution remaining after separation may be refortified by the addition of more H 2 O 2  and H 2 SO 4  thereto. Alternatively, more H 2 SO 4  may be added prior to cooling. The reactivated solution may be recycled to an etching station.

Abstract: 547,413. Centrifugal machines. BABCOCK & WILCOX, Ltd. Feb. 25, 1941, No. 2536. Convention date, July 30, 1940. Addition to 526,825. [Class 23] A centrifugal separator of the kind described in the parent Specification for use in a tubular boiler of the kind described in that Specification has a vapour outlet arranged eccentrically to the whirl chamber; the eccentricity serves to increase the distance between the vapour outlet and the side of the whirl chamber just in front of the entry. The whirl chamber 10 has a tangential inlet 12 and after the separating action the dry steam passes up through the outlet 14 formed by the cylindrical flange 15 of the cover 1, the opening being eccentric to the chamber. The inlet 12 enters the chamber near the position of maximum distance between the flange 15 and the wall of the chamber. The separated liquid escapes between the vanes 26 in an annular space between the wall of the chamber and a flange on the disc 28. A curved plate 30 is provided to prevent the space round the flange 15 from flooding with the consequent passage of water through the outlet 14. A plate separator 18 is arranged above the outlet 14. Separators of this type are arranged in two lines in the boiler, the lines being attached to longitudinal plates 56, 57. Each separator is secured by flanges 52 and bars 55, 60 with bevelled edges, as shown in Fig. 4. The plates 56, 57 by plates 80, 81, 82, 83 to form, with the wall of the boiler, a compartment 95 which receives the steam and water from the steam generating tubes. The water is discharged from each separator over an inclined baffle plate 27 towards the central region of the boiler.

Abstract: 1,068,456. Electric selective signalling. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI (ACEC). Jan. 20, 1966 [Jan. 28, 1965], No. 2662/66. Heading G4H. A circuit which gives a corresponding output when one of the inputs is energized but not when more than one are energized, comprises a number of magnetic rings (1, Figure not shown), each normally maintained saturated by a permanent magnet (2) and each having a primary winding (P1-Pn), a secondary winding (S1- Sn) and a desaturating winding (C1-Cn), the primary windings being connected in series to an A.C. source (B1-B2) through a resistor (R). The arrangement is such that if none of the control windings is energized the impedance of the primary windings is low and the secondary windings give no output, but if one of the control windings (C1-Cn) is energized it causes the corresponding secondary winding to give an output. In this condition the impedance of the primary winding is high so that if more than one control winding is energized the outputs from the secondary windings are too low to provide an effective signal.

Title: Improved process for obtaining textile fibres of high quality from the skins of fish such as, in particular, those of the chondropterygii-selachii
IPC: D01F4/00
Filed: 1928-01-27
Abstract: 284,297. Ehrenreich, A. Jan. 27, 1927, [Convention date]. Fibres, obtaining; retting.-Textile fibres are obtained from the skins of fish, particularly of the shark family, by submitting the skin to treatment by an enzyme such as trypsin to disintegrate the intercellular substances, tanning, and separating the fibres by carding and opening machines. The skins, after a short treatment with e.g. lime are treated with trypsin, the material known under the registered trade mark of " oropon," or extracts prepared from the glands of the shark family, such as the gland which corresponds to the pancreas of mammals. The treatment lasts for 24 to 30 hours and a temperature between 35‹ and 40‹ C. is employed. The skins are then tanned by any suitable process and the fibres are subsequently separated. After the treatment with enzymes colloids of the type of gum tragacanth and tragasol may be applied. The tanning process may be applied to the fibres after separation.
