Patent GB-834197-A (GB)
Title: Process for the continuous preparation of titanium and zirconium subchlorides, respectively
IPC: C01G25/04
Filed: 1956-09-18
Abstract: Titanium or zirconium sub-chlorides are prepared by reducing the tetrachlorides with metallic titanium or zirconium in a reaction medium containing finely-divided sodium chloride, at a temperature between 97 DEG  C. and the melting-point of the reaction mixture, the amount of metallic titanium or zirconium being 25 to 75% of that required for complete reduction of the tetrachloride. The required titanium may be obtained by first reacting stoichiometric amounts of sodium and titanium tetrachloride in solid finely-divided sodium chloride, the resulting reaction mixture then being reacted with further titanium or zirconium tetrachloride.  The titanium or zirconium subhalides formed appear to exist at least partially in the form of complexes or double salts with the sodium chloride, but the major amount of the sub-halide formed may be separated from the sodium chloride by dissolving in a 20% solution of hydrochloric acid and filtering to remove the insoluble sodium chloride.  The resulting solution of sub-chlorides may be concentrated by vacuum evaporation. The mixture of sodium chloride and titanium or zirconium lower halides may be used without separation as a reducing agent for acetylenic carbinols and aromatic nitrocompounds.  According to the examples: (1) a reactor having an argon or helium atmosphere is charged with dry sodium chloride of particle size 0.75 mm. Sodium and titanium tetrachlorides in stoichiometric amounts are added and the reaction mixture agitated to form extremely finely subdivided titanium.  The reaction mixtures maintained below 300 DEG  C.  The resulting mixture of titanium and sodium chloride, preferably in a 1 to 4 molar ratio, is then introduced into a stirred reactor under an argon or helium atmosphere, heated to 150 DEG  C. and titanium tetrachloride added thereto dropwise.  The reaction mixture is maintained at 150 DEG  to 200 DEG  C. with stirring and a reaction mixture containing about 70% of titanium trichloride results.  If dissolved in 20% hydrochloric acid a violet-coloured solution results, containing titanium trichloride.ALSO:Titanium in finely divided form, for example of about 50 millimicrons size, is obtained by reducing titanium tetrachloride with metal sodium in a dry finely divided sodium chloride reaction medium, preferably of particle size from 60 to 75 microns.  The reaction is preferably effected with vigorous stirring at below 300 DEG C. under an inert gas atmosphere.

Abstract: 1,151,730. Magnetic storage arrangements; transistor pulse generating circuits. TEXAS INSTRUMENTS Inc. 15 Sept., 1966 [15 Sept., 1965], No. 41299/66. Headings H3B and H3T. An anisotropic thin film storage element is read out non- destructively by a short duration current pulse which only partially rotates the flux towards the hard direction, the pulse being of less than 5 nanoseconds duration and having an amplitude exceeding that of the word and digit write current pulses. In a matrix store the element may be a discrete region of a continuous storage film formed on a conductive substrate such as aluminium, the film being overlaid with orthogonal word and digit copper strip conductors insulated by layers of polyethylene terephthalate. The read pulse generating circuit as shown in Fig. 6, uses a step recovery diode circuit comprising a charge storage diode 74 and a shorted stub 71 in association with a capacitor 73 and variable resistor 72. The read pulse is produced at terminals 61, 62 in response to a read command pulse RWC which turns on transistors 75, 76, the read pulse passing to a word line 43 selected by opening a transistor gate pair 67. For writing, a write command pulse WWC is applied at terminal 82 which turns on transistors 78, 79 and 80 to allow word current to pass through diode 81 to the selected word line, the word current reverse-biasing diode 64 and effectively isolating stub 71 from the gate transistors 67.

Abstract: 1,072,116. Automatic control of aircraft. ELLIOTT BROS. (LONDON) Ltd. Oct. 14, 1964 [Oct.21, 1963], No.41441/63. Heading G3R. In a beam guidance system for an aircraft, beam error signals representing displacement of the aircraft from track are combined with integral of bank signals to control the ailerons. In Fig. 2, aircraft ailerons 25 are automatically controlled by signals from the bank pick-off of a gyro vertical 20 and signals from a bank rate gyro 21. To maintain the aircraft on a radio defined track, signals from a localizer receiver 26, together with an integral of these signals developed in a unit 36, also control the ailerons through a limiter 30. Signals from the bank pick-off of the gyro vertical 20 are also integrated at 32 and added to the control system, but these signals are washed out, if they persist unduly, by a feedback unit 34. In a modification, a second wash-out unit is provided and the two wash-out circuits controlled in dependence on signals from the localizer receiver.

Abstract: 1336656 Storage system; rotary elevators AU RO Srl 6 Sept 1971 [4 Sept 1970] 41548/71 Headings B8A and B8E A device for transporting or storing articles such as motor vehicles comprises upper and lower parallel tracks 1, 1<1>, a plurality of article supporting platforms P displaceable along the tracks and means at both ends of the tracks to transfer the platforms from one track to the other, the transfer means comprising two rotating transfer arms 12, 12<1> and 13, 13<1> associated with first rails of the tracks and a single rotating transfer arm associated with second rails of the tracks. The platforms run on the tracks through two rollers 3 and 4 on one side engaging the first rails and one central roller on the other side engaging the second rails, pins 6 on the platforms engaging driving sprockets for motivation of the platforms along the tracks. Each transfer arm comprising supports at diametrically opposed positions on the ends of the arm, to support the appropriate axle of the track engaging roller. Since the distance between the rotation axes of the arms 12, 12<1>, and 13, 13<1> is less than the distance between the two supports of each arm, arcuate slots 18, 19 are provided in the arm 12, 12<1> permitting the passage of the roller 4 supported by arm 13, 13<1> during transfer, the plane of rotation of the arm 12, 12<1> being spaced outwardly of the plane of rotation of the arm 13, 13<1>, in relation to the tracks.

Title: Cine cameras

Filed: 1975-10-13
Abstract: 1477786 Exposure control in cine cameras K VOCKENHUBER and R HAUSER 13 Oct 1975 [24 Oct 1974] 41764/75 Heading G2A A cine camera has a shutter which normally operates with a fixed exposure time, a photoelectrically controlled diaphragm, and means, responsive to adjustment of the diaphragm beyond a maximum aperture, for adjusting exposure time to provide correct exposure. As shown, a diaphragm motor 90 is controlled by a differential amplifier 22 connected in a bridge circuit which includes a photo-resistor 10 and a film speed or filter factor resistor R2. Motor 90 adjusts the lens diaphragm 70 and a photo-cell diaphragm 45 until the bridge is balanced. The maximum diaphragm aperture is set by adjusting a stop 170 on the diaphragm ring 40. If this maximum value is reached, stop 170 opens a switch 47 to switch off motor 90 and closes a switch 48 to turn on a thyristor 290 and a warning light 21. When shutter 8 opens it closes a switch 49, 50 and since thyristor 290 is now conducting, a transistor T1 is turned off to switch off the shutter motor 12 and T2 is turned on to short the motor, thus stopping the shutter in its open position. An integrating capacitor C2 charges through a second photoresistor 15 to trigger a switching circuit 36. This turns T2 off and turns T4 on to restart the shutter motor. In the embodiment of Fig. 2 (not shown), the otuput of the differential amplifier is applied to a galvanometer (9), which adjusts the diaphragm, and to an RC circuit (R4, C1). If the maximum diaphragm aperture is reached, but the bridge is not balanced, the differential amplifier output cannot be reduced to zero and the RC circuit charges up and triggers a switch (29) to bring the photo-electric shutter control circuit into operation. This includes a mechanical shutter stopping arrangement (31) as opposed to the transistorized arrangement of Fig. 3.
