Abstract: 1293593 Resistors LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 12 Nov 1969 [18 Nov 1968] 55470/69 Heading HIS [Also in Division C7] In a method of automatically adjusting the resistance of resistors in a thin-film circuit by anodization of their surfaces whilst their resistances are monitored by an A.C. bridge, a pasty electrolyte is spread on each resistor through a mask. An apparatus is described which will adjust the resistances sequentially. A substrate carrying a circuit is placed in a positioning device (13, Fig. 2, not shown, arranged as described in Specification 1,254,438) which is attached to a mask 3, Fig. 1, hinged at 5, which is swung on to the support base 2 and locked in position. Pasty electrolyte is spread on the resistors through holes 12a ... 12d in the mask. A vacuum pump working through orifice 11, Fig. 4, holds the substrate on the plastics seal 9, and the mask 3 and positioning device are removed. The A.C. bridge contacts (15a, 15b, Fig. 5, not shown) having jointed arms 17 and gilded metal tips 16, Fig. 4, are carried in radial slots 14 in a circular insulating plate 4 hinged at 7 to be lowered over the circuit. An insulating plate 22, secured above plate 4, carries the D.C. contacts 20 having micrometer adjustment screws 23 and gilded tips  21 which pass through the central hole 8 in plate 4 to contact the electrolyte and middle points of the resistors. As shown in Fig. 4, there are three contacts for each resistor. A basic circuit for comparing a resistor (R, Fig. 5, not shown) with a standard resistor (E) and stopping the oxidizing current by a comparator (C) and relay (r), is described. If one such circuit is provided for each resistor, they may all be adjusted simultaneously. On the other hand, a single circuit may include a system for switching in each resistor and the corresponding standard resistor in turn. More efficient is a system of several circuits working simultaneously, each (Fig. 6, not shown) of which handles say for resistors (R 1 -R 4 ) in turn.

Filed: 1970-11-25
Abstract: 1336317 Data transmission systems LICENTIA PATENT-VERWALTUNGS GmbH 25 Nov 1970 [25 Nov 1969 15 Jan 1970] 56140/70 Heading H4P Serial binary-coded data for transmission is further encoded by words representing particular bit patterns of different lengths, the patterns being searched for as the data is shifted bit by bit by searching for all the patterns in parallel and in order of the increasing pattern length in the direction of data flow, words representing patterns so recognized being transmitted in the appropriate sequence. In Fig. 3 data on shifting through register 21 is examined by groups 22 of AND gates. The AND gates have a particular pattern of true and inverted inputs to recognize the particular bit patterns, each group of gates pertaining to a pattern of a particular length. Any AND gate responding causes the corresponding code word to be read out from the corresponding register 24 into an output register 25. Delays 291, 292 inserted in the read-out lines to the registers ensure that the code words are read out to the buffer store 27 in the correct sequence. To avoid a long pattern of bits once recognized being subsequently recognized as a number of shorter patterns as the bits proceed through the register, counters 289, 282 are set to particular counts on the first and second groups of AND gates responding, which inhibit the read-out of the registers 252, 253 until the counters are clocked down to zero by which time the patterns will have been passed out of the register.

Abstract: 1,205,023. Electrolytically purifying solutions; mercury cathode cells. ALBRIGHT & WILSON (MFG) Ltd. Dec.18, 1967 [Dec.19, 1966], No. 56641/66. Heading C7B. A cation impurity having a deposition voltage less than the evolution voltage of hydrogen is separated from an aqueous solution of the cation impurity in admixture with a major proportion of another or other cations all having deposition voltages greater than the evolution voltage of hydrogen by electrolyzing the solution under conditions such that sufficient hydrogen is evolved at the cathode to carry the cation impurity, when deposited on the cathode, to the surface of the electrolyte and the other cations substantially remain in solution. By the process Fe or V cations can be removed from solutions containing alkali metal cations and Cu can be removed from Mg cations. The difference in deposition voltage between the impurity cation and other cation(s) must be at least 0À2 volt. All voltages are those obtained under the conditions used. The term "cation" includes cations in the complexed as well as the uncomplexed state since one or more of the cations may be incorporated into a complex so that the desired separation of deposition voltages may be achieved. Fe may be separated from an aqueous sodium phosphate solution using a pH of 4À5, voltage between 6 and 7 volts, a Hg cathode, a Pt anode and a cathode current density of 30 to 150 MA/cm<2>. The Fe forms a scum which can be skimmed from the solution surface. Settling of the Fe can be inhibited by adding a surface active agent to the solution, e.g. an alkyl benzene sulphonate. Some surface active agents. e.g. a mixture of sodium dodecyl benzene sulphonate and ethoxylated alkanolamide and a hydrotrope improve the current efficiency of the process. The electrolysis may be performed in a (Registered Trade Mark) "Perspex" tank with a Hg cathode C, Pt wire anodes surrounded by porous diaphragms E, electrolyte distribution manifold A and electrolyte outlet B. The spaces within the diaphragms (E1, E2, E3) Fig.1, (not shown) are inter-connected by pipes F and part of the feed electrolyte is fed through these spaces.

Title: Optical Mass Store
IPC: G11B11/105
Filed: 1968-11-29
Abstract: 1,191,079. Magnetic storage arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Nov., 1968 [1 Dec., 1967; 30 Oct., 1968], No. 56788/68. Heading H3B. [Also in Division G4] An optical mass store has a storage plane divided into storage elements, and a controllable electro-optical light-beam deflector succeeded by a multiplying optical system is provided for sweeping an optical scanning beam composed of sub-beams over the storage plane. In Fig. 8, light from a laser Q is deflected in digital electro-optical deflector A and split into sub-beams by a " multiplier " V (which uses birefringent prisms or holographic imaging). There is one sub-beam for each of a number of squares F of a storage plane S, each square holding an array of bits. The light from one of the squares is selected by a second electrooptical deflector A 2  and passed to a detector D, in read-out. For writing, the light from laser Q is modulated with the data but only one of the sub-beams affects its square, viz. that square on which light from a laser Q 1 , passed through a beam-splitter ST, is directed by deflector A 2 . The beam-splitter ST may be a half-silvered mirror in which case the light beams incident on it from the two sources Q, Q 1  are arranged to be linearly polarized at right angles. Alternatively, a dichroic beam-splitter ST may be used, the two beams being of different wavelengths. The laser Q 1  may shine on the storage plane S from the left, through a third electro-optical deflector, or a movable mask may be used to select the square to be written in. Light fibres may be used after the storage plane S. An array of detectors, behind respective squares or fed from respective groups of squares, may be used. Writing may be performed in a plurality of squares simultaneously, using a " multiplier " after laser Q 1  or using different modes of laser Q 1 . Simpler embodiments dispense with some of the above features. The storage may be permanent e.g. photographic (silver halogen and diazo) or thin metal films selectively evaporated by laser Q (more intense or scanned more slowly, than for reading), or erasable e.g. photochromic or phosphors SrS(Eu, Sm) or magneto-optical (e.g. gadolinium iron garnet GdIG, or MnBi). In the magneto-optical case, writing is by heating above the Curie point using the laser(s), a controllable magnet being provided for each square (in which case all squares can be written in simultaneously) or only one magnet for the whole plane S being provided, and reading utilizes the Faraday effect (rotation of plane of polarization).

Title: Automatic Change Speed Transmission
IPC: F16H61/00
Filed: 1966-12-22
Abstract: 1,167,550. Change speed control. FORD MOTOR CO. 22 Dec., 1966 [5 June, 1966], No. 57414/66. Heading F2D. Relates to a fluid pressure control system for an automatic change-speed gear for motor vehicles, wherein pressure in a main line 106, supplied by an engine-driven pump 28 and determined by a Main Regulator valve 108, is supplied to ratio-establishing friction clutch and brake servomotors under the control of Automatic (vehicle speed (Governor)) and engine load/demand ((TV) responsive) 1-2 and 2-3 Shift valves and a Manual Control valve 148 having positions " R " (Reverse), " N " (Neutral), "D2" (2-3 autoshift), "D1" (1-2 and 2-3 autoshift) and " L " (Low, no auto upshift when " L " is selected whilst stationary). In such a system, when the Manual Control valve is in " D1 " or " D2 " position, the spool 390 of a Coasting Boost valve is held by main line pressure, directed through a line 180, in its upper position to direct TV pressure, from a Cut-Back valve 356, to a Pressure Booster 128 acting on the Main Regulator valve; and when the Manual Control valve is in " L " position, the line 180 is exhausted to allow the Coasting Boost valve spool to be moved by Vehicle speed responsive Governor pressure in a line 200 against main line pressure in a line 393, at high vehicle speeds, to direct main line pressure to the Pressure Booster. This prevents a reduction in main line pressure when the vehicle is coasting at high speed and the engine carburettor throttle is at its minimum so that the clutch and brake have adequate capacity for the coasting torque. The Coasting Boost valve also acts, when the Manual Control valve is moved to " L " position, to reduce undesirable 2-1 downshift tendencies, and consequent vehicle lurching, obtained by opening the throttle while the vehicle is travelling at a relatively high speed. In this respect, main line pressure is increased by increase in TV pressure due to throttle opening (the TV pressure acting on the Pressure Booster) and acts, through the Manual Valve in " L " position and a line 176, in a downshift direction on the 1-2 Shift valve. To offset this, the increase in main line pressure acts on the Coasting Boost valve spool 390 to reduce the main line pressure in the line 146 to the Pressure Booster. The control system is similar to that of Specification 1,123,081, with the exception of the Coasting Boost valve described above; the Forced Downshift valve, 372, which is mechanically linked with the throttle and which when shifted rightwards connects main line pressure in the line 180, from the Manual Control valve, to the 1-2 and 2-3 Shift valves for downshifting thereof; and the 1-2 Shift Capacity Scheduling and Accumulator valves which comprise a modifier valve 402 and a shift regulator valve 404 and provide gradual energization of the Intermediate Brake servo apply chamber modified by TV pressure acting on the valve 402.
