Abstract: 1389154 Cathode-ray tube circuits; sawtooth current generators II EFIMOV M L LIFSHITS D D NIKIFOROV V P IVANOV L E LINETSKY V G LAZAREV and A I BRENIN 18 July 1973 34252/73 Headings H4T and H3T [Also in Division H1] A device for focusing and deflecting the electron beam of a cathode-ray tube comprises two series connected coaxially disposed windings 4, 5 (Fig. 1), the planes of the turns in each winding being symmetrically inclined at the same angle α relative to the axis 6 the windings being connected to an output stage 7 which is supplied from a power source 9 and a sawtooth voltage scanning frequency source 10. In operation, the sawtooth voltage unbalances a bridge formed by windings 4, 5 and resistors 12, 13 and transistor 11, causing equal and opposite currents to flow in the windings 4, 5, so that a constant current flows through resistor 16, windings 4, 5 and resistor 20. This current produces the required magnetic focusing field and to ensure constancy stabilization is effected by utilizing any variation in the voltage across resistor 20 to control the base of the transistor via diode 19 and resistor 18. An additional winding connected across the power source 9 may be employed to produce an additional focusing field which adds to the main focusing field produced by windings 4, 5 and adjustment of the current in such additional winding is stated to allow better matching between windings 4, 5 and the output stage 7 (Fig. 3, not shown). When the beam is also to be deflected in a second direction a second pair of suitably orientated windings 9 and appropriate drive circuitry is employed. The invention is stated to be suitable for portable T.V. cameras for use with video tape recorders, in closed circuit T.V. applications and with T.V. cameras for inspection of smalldiameter tubes.

In a process for growing an epitaxial layer of a III-V semi-conductor compound by a transport reaction in which the solid compound is converted in a reaction vessel in the presence of a reaction gas into gaseous substances which are conveyed to a point in the vessel at a temperature different from that of the starting material and react to re-form the compound, an additive which reacts with the less volatile of the component elements of the compound to form a non-volatile nitride is added to the reaction gas. The compound may be GaAs, GaP, InAs or InP and may be deposited on a monocrystalline carrier of the same or different material, e.g. GaAs on GaAs or Ge. The additive may be NH 3  gas (which forms GaN with Ga) and may be produced by vaporizing aqueous ammonia solution or liquid NH 3 , or by decomposing solid ammonium carbamate. The reaction gas may be a mixture of H 2 O and H 2  in the mole ratio 0À1-0À3. The transport may be effected by passing the reaction gas first over the powdered compound and then over the carrier (as in Fig. 1) or by using immediately adjacent compound and carrier, e.g. by arranging a carrier plate above the powdered or tabletted compound and separating them with an annular spacer (as in Fig. 2).

Abstract: 1,005,190. Correcting curves of railway tracks. F. PLASSER, [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Sept. 28, 1961 [Dec.15, 1960], No. 34919/61. Heading S1F. In a method of aligning railway tracks, particularly curved sections thereof, the desired position of individual points along the track is ascertained and the difference between them and the actual positions of the track is noted e.g. on the web of the rail. Assuming that the track G, Fig. 3, has been corrected up to and including the region 1, 2, 3, a tensioned wire S 2 , or other means representing a straight reference line such as a sighting line or beam of light or high frequency waves, is set up extending from point 2 into the uncorrected. region of track and is displaced laterally from actual track position 4 to the desired position 4<SP>1</SP>. As a track aligning machine is moved from point 3 towards point 4, the track is corrected with reference to line S 2 . This is done by arranging a wire or other control line S 1  extending between points 1 and 3 and moving bath along until point 1 is at 2 and 3 at 4, the track being moved so that chord distance 2A gradually changes to a value equal to 3C. However to avoid a variable value of distance 2A the control wire may be arranged as S 0  with end at 3<SP>1</SP> suitably displaced from point 3 so that distance 2B is constant and distance 33<SP>1</SP> gradually changes to distance 44<SP>1</SP> as the ends of control wire So which were at points 1, 3, approach points 2, 4. Suitable apparatus is shewn in Fig. 4, wherein the reference wire 13 extends between a fixed anchorage on rear truck 19 and a laterally adjustable anchorage on forward truck 17. The control wire 14 extends between a fixed anchorage on rear truck 20 and an anchorage 15 on the track aligning machine 10 which is so adjusted by a transmission 16 connected to the wheels of the machine 10 that as members 10, 20, move along the track G the supervisory element 23 engaging wire 14 is a constant distance along support 22 on truck 19 when the track is correctly aligned. Element 23 may have an electrical contact engaging a fixed contact on support 22 to stop the aligning tools 11 on machine 10 at the correct position. The adjustment of the projecting end of arm 12 to contact wire 13 may be used for bringing the transmission 16 for the adjustment of anchorage 15 to the correct initial position.
