Title: Microprogramme unit for a data processor
IPC: G06F9/26
Filed: 1973-07-18
Abstract: 1443064 Microprogramming INTERNATIONAL COMPUTERS Ltd 17 July 1974 [18 July 1973] 34216/73 Heading G4A An index address derived from an instruction is used to access an index store 40 holding a table of start addresses for microprogram routines in a microprogram store 10. Each word accessed from store 40 may have additional bits, not required to address microprogram store 10, for use as an extension to the start microinstruction, e.g. relating to flags, conditions or indicators to be used in executing the instruction or for use as a scratch pad address. Addresses in index store 40 may also be derived from a de scriptor 101 pointing to an indirect operand or from an interrupt input 56. The index store 40 has two output registers 60, 61 for receiving the start addresses of the first and subsequent microprogram routines respectively required to execute an instruction. Whenever the start address of the first routine of a microprogram is transferred from register 60 to microprogram store address register 11, control signals n, (n + 1) and (n + 2) are produced in sequence to (n) decode, 34, the function code F of the current instruction gated into a register 14; (n+ 1) access store 40 with the decode of F to read the corresponding microprogram routine start address into register 61, and decode the function F and operand K (direct or indirect) fields of the next instruction gated into register 13; and (n+2) access store 40 with the decode of FK to read the start address of the first microprogram routine of the next instruction into register 60 and at the same time decode, 48, a data type field DT of a descriptor 101 required for obtaining the main store address of an operand. Thereafter, as each microprogram routine is initiated by withdrawal of the corresponding start address from register 61, successive control signals (n+3) to (n+6) are produced to load start addresses into register 61 corresponding to the DT, DZ, F and DZ fields of the current instruction and descriptor, DZ indicating data size (32, 64 or 128 bits for example). The same basic sequence of microprogram routines is available for each instruction, but certain types of instruction do not require the full sequence. Thus a direct read instruction which does not have an associated operand descriptor 101 only requires routines corresponding to FK and F. Wherever the sequence ends, the start address for the first routine of the next instruction is immediately available in register 60.

Title: Improvements in or relating to apparatus for the treatment of steel strip
Inventor: SALT FREDERICK WILLIAM
IPC: C25D7/06
Filed: 1959-10-14
Abstract: 905,278. Electrolytic treatment of steel strip. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 5, 1960 [Oct. 14, 1959], No. 34811/59. Class 41. In a steel strip processing line a wide variety of processes can be carried out, examples are electrolytic tin, zinc or nickel plating, iron flashing, electrophoretic deposition of organic materials or aluminium, and electrosmoothing. As shown, steel strip 27 is drawn by a bridle unit 12 from an uncoiler 11a with tensioning rolls 11b through treatment stations. These stations include rubber-lined steel tanks 18 to 23 each divided by a vertical partition into two compartments. The treatment comprises removing excessive oil and grease by felt pads (not shown) soaked with trichlorethylene; cleaning by cathodic alkali treatment and spray washing in tank 18; electrolytic etching or smoothing and spray washing in tank 19; electrolytic tin-plating or other electrolytic or electrophoretic coating in tanks 20 and 21; spray washing also in tank 21; drying at 46 ; flow brightening by heating the strip by A.C. between rolls 40, 41 and 42 and then passing through a quench tank 48; making the strip cathodic in sodium dichromate solution in tank 22 whereby it is coated with a film of mixed chromium and tin oxides, and then spray washing; oiling in tank 23 containing a heated and circulating emulsion of cottonseed oil in water; and drying at 26. The treated strip is then cut into lengths by a guillotine 15. Each washing station comprises a plurality of water jets which are aligned so that in operation the water impinges at a small angle on one face of the strip, near the edge, and passes across this face to the opposite edge. Current is supplied to the strip via conductive rolls 29 and 32 to 44 and electrodes of opposite polarity are suspended in the treatment tanks. The current to the tinplating tank can be finely controlled. The strip passes between squeegee rolls on leaving the tanks. Drying at 46 is by radiant heaters (not shown) which heat the rolls 25, 40, 41 and also by warm air blown through asbestos ducting 24. Drying at 26 is by similar means. A strip marker is provided which can be operated when the strip speed and currents in the various stages have been adjusted to their required value. A method of removing strip and inserting new strip in the processing line by using a " Terylene " (Registered Trade Mark) rope is described.

Abstract: 1,129,378. Multicolour yarns. J. F. ELSAESSER. 4 Aug., 1966 [11 Aug., 1965], No. 34968/66. Heading B6C. Multicolour yarns in which the colour varies continuously around the peripheries are produced by an uninterrupted process which comprises (a) initially passing the yarn over a printing paste-applicator roller which is coated with a thin film of printing paste mixed with a dyestuff, thus applying a ribbon of dye to the yarn and (b) directly afterwards treating the complete periphery of the wet yarn leaving the roller with a solution of a second dyestuff. The printing paste-applicator roller preferably has a slightly porous surface and rotates in the opposite direction to the direction of travel of the yarn. The contact time between the yarn and the roller may be varied by mounting a carrier roller in front of the paste roller which can have its height altered. A number of printing paste-applicator rollers can also be used to apply a number of separate ribbons. The second dyestuff is preferably applied by passing the wet yarn from the paste roller through a pair of rollers, the lower one of which dips into a bath containing the dye, which exert a squeezing action.

Title: Frequency stabilising circuit for electric frequency modulators

Filed: 1945-12-28
Abstract: 606,359. Automatic control systems; oscillator frequency control. STANDARD TELEPHONES & CABLES, Ltd. Dec. 28, 1945, No. 35064. Convention date, April 23. [Class 38 (iv)] [Also in Group XL (c)] A frequency modulated thermionic oscillator comprises a tube V1 connected in an oscillatory circuit L1, C1, C2, the frequency of which is variable by a modulator tube V2 connected in series with inductance L2 across capacity C1. The application of an audio-frequency signal to grid 17 of tube V2 varies its impedance and frequency modulates the oscillator output which is fed to a network comprising in parallel two branches in which piezo-electric crystals Cr1, Cr2 are respectively connected in series with resistances R3 and R4. The crystals have resonant frequencies which are spaced above and below the limits of deviation of the carrier frequency, and the voltage appearing across R3 charges condenser C5 (which is large and may be shunted by resistor R5) negatively through rectifier V3, while the voltage appearing across R4 charges the condenser positively through rectifier V4. The D.C. voltage appearing across the condenser is applied to grid 15 of the modulator tube V2 so as to vary the mean oscillation frequency. When the mean frequency lies midway between the frequencies of the two crystals, the positive and negative charging currents applied to C5 are equal so that no control voltage is developed. A rise in the mean frequency causes the reactance of Cr2 to decrease and that of Cr1 to increase so that the positive charging current into C5 increases and the negative charging current decreases, and a positive voltage appears across C5 which biasses grid 15 of V2 to restore the mean frequency to its former value. The reverse action takes place on a fall in the mean frequency. In modifications, resistances R3, R4 may be made variable, or variable resistances may be inserted in series with the rectifiers, so that the mean frequency at which no control voltage is developed may be shifted in relation to the frequencies of the crystals.
