Abstract: 1,257,939. Gas-filled thermionic valves. M-O VALVE CO. Ltd. 9 July, 1970 [15 July, 1969], No. 35683/69. Heading H1D. [Also in Division H2] An electric circuit interrupting device comprises an envelope 1 containing a gas filling, an anode 4 and a cathode 2 between which is disposed at least one screen member 17 providing at least one aperture 18 through which in operation an electrical discharge can pass from the cathode to the anode, and means 22 for producing a magnetic field in a region of the discharge adjacent said aperture, and between said aperture and the cathode, directed parallel to the path of said discharge in that region, the maximum dimension of said aperture in a direction perpendicular to the path of the discharge in said region being sufficiently small so that, in operation of the device and when a discharge is passing, the presence of said magnetic field causes said discharge to be quenched. The cathode heater 8 is connected to a lead rod 9. The cathode 2 and heat shield 5 are supported by a member 10 connected to a lead rod 11. A tungsten rod 14, one end of which forms the anode 4, is surrounded by a glass tube 13 sealed through a re-entrant portion 12 of the glassenvelope 1. The control electrode arrangement 3 comprises three discs 17 bolted together insulated from each other and supported by a metal sleeve 19 secured to the glass tube 13. Each disc 17 has a 3 mm. diameter central aperture 18 and is connected by a wire 20 to a lead rod 21. A coil 22 providing the magnetic field is connected to a pulse generator in a protection circuit (Fig. 2, not shown, see Division H2).

Abstract: 1,259,134. Colour printing. H. KIENING. Jan. 10, 1969 [Jan. 18, 1968], No. 1516/69. Heading G2A. An illuminated transparency 12 is inspected either directly, as shown, or by projection on to a screen, and the intensities of the colour components adjusted until the result is adjudged satisfactory, the light actually being used for printing then being adjusted correspondingly. As shown, light 1 from a lamp passes through an adjustable aperture 2 to a dichroic mirror 3 which reflects red light and transmits green and-blue light. A further dichroic mirror 4 reflects the green light and transmits the blue, which is itself then reflected from a mirror 5. The light reflected from the three mirrors 3, 4 and 5 passes through respective gate apertures 6R, 6G, 6B to further mirrors 7, 8 or 9. Mirror 7 reflects the red light which falls on it to pass through dichroic mirror 8, which also reflects the incident green light. Red and green pass through the further dichroic mirror 9 which also reflects incident blue light. Thus all three colour components are reunited, and pass via a semi-transparent mirror 10 to the transparency 12. The intensity of the light passing through apertures 6R, 6G, 6B can be varied by controlling the apertures by means of operating knobs 13, the adjusted values being indicated on scales 14. The knobs 13 are adjusted individually until the subjective impression of the indicated transparency is satisfactory. The knobs 13 are all connected to a fourth knob 15, which is used to control the total brightness. Knob 15, and/ or knobs 13, are connected to a tape punching device 17, which can then be used to control the light of the printing machine itself.

Abstract: 1,265,867. Current measurement. INSTITUT ELEKTRODINAMIKI AKEDAMII NAUK UKRAINSKOI SSR. July 30, 1969, No. 38146/69. Heading G1U. A magnetic analogue memory device, for use in storing a value corresponding to an electric quantity to be measured, includes a core 1 of magnetic material having two legs, 2, 3 each carrying a control winding 4, 5 respectively and each forming a magnetic circuit with first and second poles. The first poles 7, 9 of the magnetic circuits are combined, while the second poles 8, 10 are separated by a gap 11 in which the absence of field between them can be detected by a magnetometer pick-up 12. To use the device, it is first set by applying a high amplitude pulse to both windings, to saturate the core to the maximum magnetization. The winding directions are such that the poles 8 and 10 will be of like polarity, and there will be no flux in the gap 11. A signal to be memorized is then applied to the winding 4, in the direction opposite to the set pulse. The flux in the first magnetic circuit 2 is reduced in proportion to the signal. A flux appears across the gap 11 proportional to the signal, and the core can remain in this condition more or less indefinitely. To measure the memorized signal, increasing current is applied from adjustable source 6 until the flux in the gap is again reduced to zero, as detected by the magnetometer pick-up 12. The value of this current is proportional to the original input.

Abstract: 1297343 Data selection apparatus INTERNATIONAL COMPUTERS Ltd 26 Jan 1971 3224/71 Heading G5C A data selection indicator comprises a casing 20 and a series of triangular-section rods 11-18 arranged to display one face. Each rod has a pin 22 at one end, each pin carrying a crank 26 connected-to a rod 30 so that movement of the rod 30 rotates the rods 11-18 to display alternative faces. An actuator 32 determines which faces are displayed. Selection of a piece of data e.g. the description of a patients symptons is made by means of two transparent cursors 34, 36, the ends of which pass through slots 38, 40 respectively and are carried by an endless cord so that the cursors are moved to a predetermined position by the knobs 42, 44. Thus the co-ordinates of the predetermined piece of data can be read from the settings of the actuator 32 and the knobs 42, 44. The rods 11-18 could have cross-sections other than triangular, and the indicator could be adapted to send a message including at least the cursor positions and the actuator setting to a local computer, the message signals being generated by the various positions of rotary switches mechanically coupled to each cursor drive.

Abstract: 1297683 Tape loading SONY CORP 1 Sept 1970 [24 Jan 1970] 41847/70 Heading G5R A system of rotatable arms 28, 31, 32 is used to pull a tape 14 from a cassette 11 and to wrap the tape around a heads drum 17. The arms are mounted on a plate 21 which, on rotation, causes the arms to move linearly from positions A1, B 1 , C 1  to A 2 , B 2 , C 2  and then rotatably to positions A 3 , and A 4 , B 4 , C 4 . Further rotation causes the tape to become slack and the tape then drops off tape guides (28a, 31a, 32a, Fig. 4, not shown) on the arms 28, 31, 32 and envelops the heads drum 17.

Abstract: 1297755 Crystal-pulling and zone-melting PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [4 April 1970] 25931/71 Heading B1S In the unidirectional solidification of a mixture of components capable of coupled growth to produce a crystal of lamellar geometry, a pair of flat faces maintains the lamellar array of crystallites in parallelism, by being closely spaced from one another at least in the area of initial growth. The pair of flat faces may include one or two walls (Figs. 1 and 3-8) one or two free surfaces (Figs. 1 and 2 a, b) and a plane solidification front (Figs. 4-8). In crystal-pulling techniques, a plate 13 on a ring 23 may be withdrawn, from a melt. Alternatively, as a melt 36 is progressively frozen, the parallelism, established under the influence of walls 33, 34, Fig. 3, is maintained in the widened part 32 of the cell. In an example, a cell was made from optically ground quartz plates spaced 0.5 m.m. apart and filled, by capillary action, with a homogenous entectic mixture of Ca Cl and Ag Cl. The cell was placed between a heater 74 and a cooling element 75, arranged to move a molten zone 71 throughout the length of the mixture. In a further example, the process was repeated using a homogenous entectic mixture of Pb and Sn in a similarly formed SiC cell. Other mixtures specified include entectic and non- entectic mixtures of Co and Si, Cs I and Na I, Cu Al 2  and Al, Cd and Zn, Cd and Pb, MO 2 C and Mo, Ni Be and Ni, C Br 4  and C 2  Cl 6 .
