Title: Antenna scan apparatus
IPC: H01Q1/28
Filed: 1974-08-16
Abstract: 1477325 Aerials TEXAS INSTRUMENTS Inc 16 Aug 1974 [23 Aug 1973] 36195/74 Heading H4A An aerial 40, Figs. 5, 6, which is located within a confined space, such as that between the nose radome 12 and a bulkhead 56 of an aircraft, is provided with scan apparatus whereby it is translated as it rotates, so permitting the use of an aerial larger than would be possible if it was simply rotated. As described, an internally toothed ring gear 44 is fixed to the air frame, and a motor 54 has a drive shaft 52 which is coaxial with said gear. An arm 50 is attached to said drive shaft and carries at its other end a rotatably mounted shaft 48. A planetary gear 46 is fixed to the shaft 48, and meshes with the ring gear 44. The aerial 40 is also fixed to the shaft 48. The ratio, pitch circle diameter of gear 46 to pitch circle diameter of gear 44, is 1 to 1À5, and as the arm 50 makes one revolution, so the aerial 40 also makes a half revolution in the opposite direction. The figure described by the aerial is consequently generally triangular in shape, instead of circular (Figs. 7, 8, not shown). In another embodiment only a forward portion of the fixed ring gear is used, and although the scanning angle is reduced (e.g. to 30 degrees) the apparatus becomes particularly suitable for use in high performance aircraft having conical noses (Figs. 1, 2, 3, not shown). Instead of gearing, a belt driven system may be used, as shown in Fig. 10. A drive shaft 104 has an arm 102 fixed to it which carries at its other end a rotatably mounted shaft 100, the aerial 40 and a pulley 101 being fixed thereto. Another pulley 109 is mounted coaxially with the driving shaft 104, and is fixed in relation to the airframe. The ratio diameter of pulley 101 to diameter of pulley 109 is 1 to 1À5, and the two pulleys are coupled by a belt 110.

Title: Method for cooling the discharge tank of a liquid cathode rectifier
IPC: H01J41/12
Filed: 1960-10-27
Abstract: 900,894. Automatic temperature-control systems. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 27, 1960 [Oct. 28, 1959], No. 36864/60. Class 38 (4). [Also in Group XL (a)] In a method of cooling the condensing chamber of a liquid cathode rectifier having a long, preferably horizontal, tank in which a current of cooling air is led longitudinally along the tank through a casing 2 surrounding the tank, a circuit sensitive to the temperature of the tank causes complete interruption of the air current when the temperature of the tank decreases to a fixed value and causes the current of air to be restored to full velocity when the temperature increases to a higher value. A thermistor 5 is placed half-way along the tank and is connected to the secondary 9 of a transformer, the two primaries 7, 8 of which and two resistances 13, 14 form an A.C. bridge circuit which is the control circuit of a 2-step amplifier. The bridge circuit output 17, 18 is fed via rectifier 33 to windings 31, 33 to increase the inductance of one and decrease the inductance of the other of two transductors 25, 25<SP>1</SP> and so to energize or de-energize two-phase motor 30 to open or close damper 4. The transductors form the other step of the amplifier and are supplied via rectifier 24, variable resistances 28, 29, and windings 26, 27. One winding of motor 30 is fed directly, the other via condenser 34. Air is circulated by fan 3 over the rectifier tank which may have cooling ribs, the area of which increases in the direction of flow of the air current. The mercury rectifier has main anodes in one or more rows as in Specification 848,310 and a cylindrical tank. Capacitor 11 is for reactive power correction and may, if desired, be across primary 9.

Abstract: 1,148,528. Forms of wood. G. W. WYNN. 26 Aug., 1966 [27 Aug., 1965], No. 37019/65. Heading B5L. An elongate sectional member comprises a series of spaced coplanar slits 4, Fig. 1, the plane of the slits being directed parallel to the longitudinal axis of the member. The member may be rectangular having one face twice as wide as the other with the slits midway between the narrow faces 6 which may be formed with grooves 8. Holes 10 extend between the grooves, alternate holes intersecting the slits and being formed with counterbores 12. Two sectional members can be joined together by sawing at right angles to and at the opposite ends of a slit to form openings 14, as shown in Fig. 2. The joints may be secured together by glue and a dowel passing through the holes in the exposed faces of the slits; alternatively, screws or bolts may be used. The sectional members may have 1, T, X or, as shown in Fig. 5, angle cross-section. The slits and holes may not penetrate both faces of the members but may be blind, or may extend from both faces but not join at the middle. Hinges or catches may be received in the holes or the holes may receive the pegs 32, 34, Fig. 7, of angle members 30 for effecting a T-joint between two members. Mitred joints between members can be effected by an angled dowel which engages one hole in each member. In another embodiment, the member is laminated having an inner lamination 44, Fig. 10, between outer laminations 46, the slits 4 not extending to the outer faces of the member. Alternatively, the slits may be formed at the interfaces of the laminations by not applying adhesive where the slits are to occur. In a further embodiment, the axes of the holes lies in the plane of the slits or parallel to such plane. In yet another embodiment, the member is formed with pairs of parallel slits 58, Fig. 13, adjacent a semi-circular raised region 56 of the grooves 8 in the narrow faces. Holes 10 are located adjacent and parallel to the ends of the slits and when bored out to intersect the slits form slots 60. Cuts from the outer surfaces of the member to the slits produce tongues 62. In a similar embodiment, the member has a pair of grooves in each narrow face, each groove having a semi-circular raised portion and aligned pairs of slits.

After demodulation, the resulting signal is fed via variable threshold control R 1  to actuate indicator relay RL 1 . Actuation of this relay feeds a signal to variable delay R 2 , C 3  and after a predetermined delay a second indicator relay in the collector circuit of transistor 9a is actuated.
