Abstract: 923,167. Control systems for vehicle lighting apparatus. ROBERT BOSCH G.m.b.H. Dec. 29, 1961 [Jan. 4, 1961], No. 46617/61. Class 38 (4). The lighting installation of a mechanicallypropelled vehicle is arranged so that headlight flashing signals and head-light dipping operations can be controlled by a single switching device. A motor vehicle lighting system comprising head-lights having main beam filaments 11 and dipped beam filaments 12 is provided with a light selector switch 14, a dipper switch 17 which is operated by way of an electromagnetic relay 16 which is controlled by a manually-operated switch 15. With the light selector switch in the OFF position O no lights are energized but operation of the push-button switch 15 energizes coil 30 of relay 16 whereupon a part 34 of armature 31 co-operates with a device 37 and causes the arm 35 to take up an alternate position and at the same time contacts 32, 33 close over which contacts the main beam filaments 11 are energized so that a head-light flashing signal is provided. Similar operations is provided when the light selector switch 14 is in the side light position I, the side lights 13 and near lights 48 being energized in this instance. When the light selector switch 14 is in the head-light position II the main beam filaments 11 or the dipped filaments 12 will be energized by way of the dipper switch 17 according to the position assumed by the arm 35. Operation of the push-button switch 15 again energizes coil 30 of relay 16 to close contacts 32, 33, without effect, and at the same time to cause the member 34 to operate the arm 35 to its alternate position, thereby causing the head-light to change from dipped beam to main beam or vice versa. In a second embodiment the armature may operate two pairs of normally open contacts, one of which pairs is in series with the dipped beam so that when the light selector switch is in the side light position I the head-light flashing signal is given by the dipped beam filaments. In a third embodiment the connection between the battery 46 and the arm 35 and the contact 32 is made by way of an electromagnetic changeover relay controlled by the light selector switch.

Title: Method of extracting aluminium,magnesium and titanium
IPC: C25C7/06
Filed: 1962-12-12
Abstract: Al, Mg or Ti is extracted by fusion electrolysis of a mixture including an alkali-metal halide and a halide of the metal to be extracted at a temperature below the melting point of the metal to be extracted and applying the voltage in brief pulses (e.g. of 0.12 sec.) interrupted by longer intervals (e.g. of 1.88 sec.) in which no voltage or a smaller voltage is applied.  Examples of electrolytes are NaCl and AlCl3, KCl and MgCl2 or NaF and TiF4. Additionally, the electrolyte may contain a catalyst produced from an addition compound of NH3 with AlCl3 or NH3 with TiCl4 respectively for Al or Ti extraction.  An oxide of the metal to be extracted may also be included.  The anode may be of the same metal as that being extracted.  In an example of extracting Al, the electrolysis is in two stages with a period of pulsed voltage (7 volt pulses) being followed by a period when the voltage is maintained at 1.4 volts.

Title: Exposure control for electrostatic copiers
IPC: G03B27/80
Filed: 1972-10-12
Abstract: 1410510 Exposure control ADDRESSOGRAPH MULTIGRAPH CORP 12 Oct 1972 [14 Oct 1971] 47220/72 Heading G2A In an electrostatic contact copying apparatus an original document to be copied passes from a measuring and control station, where a first variable quantity of light is directed through the document, to an exposure station where a second variable quantity of light, which is maintained at a fixed ratio to the first quantity passes through the document and a copy sheet, which are superimposed: at the measuring and control station the first quantity of light passing through the document is measured and its intensity varied until a predetermined value is reached, this also causes a variation in the intensity of the second quantity of light at the exposure station which is maintained at a fixed ratio to the first quantity, the emitted intensities of the first and second quantities are maintained while the document is moved to, and held in superposed relationship with a copy sheet at, the exposure station. In the embodiment shown the document enters the intensity measuring and control station and modifies a light beam passing from a lamp 12 to photo-cell 15 in an illumination sensing bridge 14. If the lamp 12 is too bright the resistance of photo-cell 15 falls, the charge on capacitor 18a in a holding circuit 18 drops resulting in a low output from amplifier 22 which causes a uni-junction 24a to fire at a high voltage level triggering an SCR 26 late in the rectified A.C. cycle and reducing the voltage on lamp 12. Lamp 12 becomes dimmer, the resistance of photo-cell 15 rises raising the charge on capacitor 18a. The output of amplifier 22 increases, uni-junction 24a fires earlier resulting in earlier triggering of SCR 26 and increasing the brightness of lamp 12. This cycle continues until a pre-selected charge exists on capacitor 18a, corresponding to a pre-selected sensed illumination, at which point stabilization occurs. After stabilization the bridge 14 is isolated from circuit 18 by a diode 16' and the document moves to an exposure station. The exposure lamp 28 has the same emission characteristics as lamp 12 and is also connected to the circuits 18, 22, 24 and 26 so that it receives the same signal as, and its intensity varies in the same way as that of, control lamp 12, the precise level of intensity for correct exposure being pre-set by a variable resistance 32. After exposure the holding circuit is reset by closing a switch 38a and discharging capacitor 18a. In alternative embodiments the circuit 18 is isolated from bridge 14 by the opening of a relay contact (16) actuated by the document leaving the control station (Fig. 1), and a single light source is provided, out of which the control beam and the exposure beam are screened.

Abstract: 1285175 Acoustic measurement of fluid flow velocity UNITED KINGDOM ATOMIC ENERGY AUTHORITY 23 Sept 1969 [4 Oct 1968] 47310/68 Heading H4D Apparatus for measuring the velocity of a fluid moving relative to the apparatus (e.g. a flowmeter or ship speed indicator) by comparing the travel times of pressure waves over a given path in the fluid respectively in and against the direction of movement comprises (Fig. 2) transducers 13, 14 each receiving continuously pulse trains transmitted by the other, and a control device prevents pulse transmission at either transducer while it is receiving a pulse from the other. The pulse received by transducer 14 is detected by receiver RX1 and gated zerocrossing detector 16 whose output triggers transmitter TX1 via gate 18. Hence TX1 pulses transducer 13 at a repetition frequency f 1  dependent on fluid velocity. Similarly TX2 is triggered by pulses received at transducer 13 and energizes transducer 14 at a repetition frequency f 2  dependent on fluid velocity. Coincidence detector 23 is arranged to give an output pulse whenever the TX2 pulse occurs within a short period after the TX1 pulse (e.g. at time C in Fig. 3); hence the output pulses are at a rate (f 1 -f 2 ) proportional to fluid velocity if the flow is in direction X. Similarly coincidence detector 23a gives output pulses at this rate if the flow is in direction Y. To avoid receiver paralysis by TX1 and TX2 being triggered too close together in time, the output pulse of coincidence detector 23 trips electronic switch 17 for applying the triggering pulse from zero-crossing detector 16 to TX1 via a delay 25 and a compensating delay is imparted to the TX2 triggering (by means of an input on line 27a). Similarly coincidence detector 23a output pulses result in delayed triggering of TX2 and a compensating delay for the TX1 triggering.

Abstract: 475,626. Making articles by electrodeposition. COMPAGNIE FRANCAISE POUR L'EXPLOITATION DES PROCEDES THOMSON-HOUSTON. April 3, 1937, Nos. 9502 and 9503. Convention dates, April 15, 1936 and Feb. 8, 1937. [Class 41] [Also in Group XVI] Goffered matrices with very small elements, suitable for making lenticular kinematographic films or the lenticulations in cellulosic screens used to show a relief effect, are made by an adaptation of the method used in the manufacture of gramophone records, i.e. by forming microscopic recesses on the surface of wax or other suitable similar material, taking from the wax an electrotype counter-matrix, and from the latter a second metallic electrotype which constitutes the final matrix. The wax, free from grains and at a suitable temperature, in the form of cylinder or a layer on the surface of a ridged rigid metal or other cylinder with the same coefficient of expansion, is engraved with a helicoidal groove of circular or other cross-section, by a heated tool, or a cutting tool of sapphire or other material, which may be heated. The wax is then metallized by silvering, cathodic bombardment, or other means, the counter-matrix of copper is deposited, and the wax is dissolved or melted. A harder metal, e.g. nickel or chromium, is then deposited on the beaded inside of the counter-matrix thus formed, and may be backed by a reinforcing layer and its withdrawal from the counter-matrix may be permitted by heating and the consequent differential expansion. Alternatively the copper may be dissolved off by acids, cut off, or, if it has been deposited in stratified layers, stripped off sheet by sheet. The radius of curvature of the lenticulations may be adjusted as desired by depositing chromium or nickel, which are deposited respectively rather on the projections than the hollows and vice versa. The matrix may then be hardened by any known method.

Lamps and photodiodes 164, 166, 168, 170 co-operate with the apertures to produce, on rotation of the disc a pair of squarewaves 90 degrees apart in phase, Fig. 9, (not shown). The squarewaves are applied to a circuit which distinguishes up and down counts of feed consumption, Fig. 2, (not shown), and the up and down counts are applied via lines c, d to units and tens counters 50, 52, Fig. 3. When an animal enters the station, sensor 18 causes counters 50, 52 to be zeroed via line b, Fig. 2 (not shown), and actuates the animal identity determination means. This last means includes an interrogation coil 22 to which a pulse is applied to activate a reed switch in an ear tag carried by the animal. The tag, Fig. 6, (not shown) includes a crystal controlled oscillator, a clock controlling the oscillator to produce R.F. pulses and a counter which causes a latching circuit of the reed switch to become inoperative after a predetermined number of pulses which number represents the code for the particular animal. The R.F. pulses are picked up by a receiver 24 and are passed to an address counter 56, Fig.3, which selects the portion of the memory means appropriate to the particular animal. When the animal leaves the station a countdown clock 94 is triggered which supplies pulses to the down input of counters 50, 52 to count the counters down to zero. At the same time, the pulses are supplied to the appropriate portion of the memory means as selected by address counter 56. Each memory portion includes a units and tens counter, Fig. 5 (not shown), and the cumulative total in each memory portion may be selected for display. If an animal bumps the hopper or entering the station to produce a down count in counters 50, 52, which down count may remain due to mechanical hysteresis effects, and if the animal does not consume enough feed to counteract this down count, then transfer of the erroneous 99 count in the counters to the memory means is prevented by nand gate 86, nand gate array 90 and nand gate 88.

An underwater drilling rig comprises a drilling tower 20 carried on a platform 12 which is guided for vertical displacement relative to a permanently submerged hollow shell 10 on hollow columns 11 extending upwardly from the shell and sealed against admission of water, the platform being partly submerged so as to contribute to the floatation of the rig when close to the shell but being above water level during drilling, and means to lock the platform against displacement on said columns. As shown, when the platform has reached its operating position, weights 22 attached to columns 13 are lowered by jacks 14 until stops 13' engage the top of the shell 10. If the operation of the jacks is continued, the stops 13' will depress shell 10 and columns 11 with the corresponding relative raising of platform 12. The shell 10 contains the major part of the effective load and is in communication with the interior of columns 11. Stabilizers constituted by cylinders 21 may be carried by the platform and counter weights consisting of metallic plates 24 and toggle links 25 may be hung from winches 23. The toggle links may be replaced by telescopic elements (not shown) including elastic devices. Also solid counter-weights (24') Fig. 4 (not shown) may be used. The floating platform may be maintained in position by anchors or by motors orientable to permit thrust in appropriate directions.

Title: Improvements in or relating to Electronic Systems and Apparatus for Recognising Printed Characters.
Inventor: PARKS JOHN RONALD

Abstract: 1,170,234. Character recognition. NATIONAL RESEARCH DEVELOPMENT CORP. 14 Nov., 1966 [12 Nov., 1965], No. 48171/65. Heading G4R. Character recognition apparatus multiplies together relatively delayed versions of an analogue signal waveform derived from a raster scan of the character, to obtain analogue shape feature indicating signals which are then combined to identify the character such that a given character is indicated only if the correct shape features occur in the correct physical disposition relative to each other. Referring to Figs. 4, 5, the waveform from a raster of vertical scans of the character to be identified is amplified logarithmically at 14 and applied to delay lines DL1-DL9 as shown. Each delay line DL1-DL4 has a delay of four scan lines and each delay line DL5-DL9 of one scan line. Tappings on lines DL5-DL9 feed adders ADR1-ADRn to recognize geometric features, e.g. straight and curved lines in various orientations. The adders feed " blur " filters BF1-BFn via antilog amplifiers ALA1- ALAn. The blur filters are low-pass filters for broadening the signal peaks to allow for circuit noise and variations in ink density. The blur filters feed weighting and combining networks CNl-CNn, one per possible character, via delays DM1 &c. which serve to bring feature signals derived from different parts of the character to the appropriate weighting and combining network simultaneously. The largest network output is selected as identifying the character. In a modification (Figs. 6, 7, not shown), blurring and combining is done in delay lines, one per possible character. Each delay line receives the outputs of several of the antilog amplifiers of Fig. 4 which are applied to respective positions along its length. Three taps, one scan time apart, on each line feed a summer respective to the line (to provide blurring between adjacent scans). Blurring along each scan is provided by limiting the response bandwidth of the delay lines. The summer outputs are gated (except during scan fly-back) to respective peak detectors, the largest output of which is selected to identify the character under control of a validity check circuit which can also produce a reject signal. In addition, the largest of the gated summer outputs is filtered to remove transients, then differentiated before being passed to two Schmitt triggers which produce outputs on positive-to-negative and negative-to-positive zero-crossings respectively. These outputs indicate the reaching of the best time to sample the previous signals to identify the character, and the " boundary " between successive characters respectively. The validity check circuit utilizes pulse lengtheners, storage triggers and logic circuitry to perform checks on the relative timing of these signals in dependence on predetermined maximum and minimum character widths. The delay lines of Fig. 5 may be eliminated by suitable choice of the tappings on those of Fig. 4.
