Title: Improvements in radiation-operated attitude control of satellites
Inventor: WANGER ROBERT PRICE
IPC: B64G1/28
Filed: 1966-01-24
Abstract: 1,132,392. Controlling satellites. GENERAL ELECTRIC CO. 24 Jan., 1966, No. 3074/66. Headings B7G and B7W. [Also in Divisions G3 and H4] An artificial satellite is stabilized in yaw by the interaction between the earth's magnetic field and electromagnets powered by solar batteries. As described, the satellite is gravitystabilized in pitch and roll by a geo-stabilizing rod (77, Fig. 4, not shown) and is in a polar orbit, the plane of which includes the sun. Solar batteries such as 2, 4 are connected to windings 34, 36 on a magnetic core 68, and are separated by a partition so that if the axis 51 of the satellite is yawed relative to the sun, one of the batteries 2, 4 is shaded, and the arms of the magnetic core are differentially magnetized, producing a restoring moment by interaction with the earth's magnetic field, since the lines of force and the sun's rays are substantially co-planar. A similar pair of solar batteries (6, 8, Fig. 3, not shown), are arranged below the pair 2, 4, shielded from them by a partition, and one pair or the other is used according to whether the axis 51 is pitched up or down relative to the sun (i.e. at different parts of the orbit). A similar set of four batteries 10, 12, (and 14, 16, Fig. 5, not shown) is provided at the other end, one set being used when the satellite is approaching the sun and the other when it is receding. When the axis 51 is approximately in line with the sun, i.e. over the poles, shades 56, 58 cover the batteries, and the system is inactive. Other shades protect the batteries from the earth reflection and from the sun when overhead. Resistors 18, 20, 26, 28 in series with the batteries heat up as current flows from the batteries, causing an increase in resistance which produces a damping effect.

Title: Improvements relating to electricity supply systems
IPC: H02G7/18
Filed: 1922-02-02
Abstract: 197,001. Siemens Bros. & Co., Ltd., and Wood, H. G. Feb. 2, 1922. Faults, indicating.-The amount of current carried by cables in an electric supply system is indicated at the central station or at other points in the system by providing one or more auxiliary conductors 4, 5, Fig. 1, of known temperature co-efficient embedded in the insulation of the cable, and measuring their change of resistance with temperature, or by inserting thermo-couples in the insulation of the cables and indicating the heating effect. A separate return cable having conductors of low resistance-temperature coefficient such as manganin can be used, or where more than one auxiliary conductor is available they may be looped. A pair of auxiliary conductors of different substances, for example copper and constantan, may be laid up in the cable, the junction providing the thermo-couple. The auxiliary conductors can be of nickel. In the system shown in Fig. 3, the auxiliary conductors in the bank of cables a between the central station GS and the point B can be looped at B and the temperature indicated at GS. Between the point C and sub-station SS2 the auxiliary conductors may be looped at C and the indication obtained at SS2, or a pilot cable may be provided between GS and SS2. For indicating over the length B to C a pilot cable may be run from the central station to the point B and the auxiliary conductors between B and C looped at C.

Abstract: 232,362. Taylor, A., and Taylor, E. W. Feb. 7, 1924. Tacheometers.-In a tacheometric telescope of the internal focusing type, means are provided whereby, in the act of focusing, the distance from the centre of the instrument to the anallatic point is automatically indicated. The anallatic point, is the point whose distance from the object focused bears a constant relation to the stadia intercept, and its position depends on the distance of the said object, i.e. on the focusing. In the form shown the telescope a is secured to the transit axis b which is pivoted in standards c. The focusing lens e is carried by a slider d having a rack f operated by a pinion g, which is rotated by the head h. The pinion is provided with teeth j meshing with a gear k which meshes with internal teeth on a rotary member in the face of which carries a scale co-operating with an index on the fixed member l to show the required distance. In another form a scale is marked on the member d and is viewed through a window in the telescope tube. Specification 215,673, [Class 97 (i), Optical systems &c.], is referred to.

Title: A fluid control valve
IPC: F15B13/08
Filed: 1967-01-21
Abstract: 1,126,291. Valves. M. GLAS. 21 Jan., 1967, No. 3255/67.. Heading F2V. A multiway fluid control valve comprises a valve body 1, a fluid inlet connection 4, a fluid  return connection 5 and two consumer connections 2 and 3, the flow path between a given consumer and the inlet or return being controlled by three series arranged valves 7, 8 and 9 each of which is individually operable by means of a cam 30 secured to a manually or motor driven shaft 29. As shown in the Figure, consumer 3 is connected to return 5, via port 19a and collector chamber 18, whilst consumer 2 is connected to inlet 4 via ports 19a. Each cam carries three cam surfaces (31a, 31b and 31c, Fig. 8, not shown), and the disposition of these in relation to the same of the remaining cams determines the sequence of operation of the valve members; the cam shaft 29, housed in a sleeve 34, is removably retained on the valve body, so that it may be removed and the valve actuating control programme altered by adjustment of the cam surfaces without altering the valves per se. An alignment diso 35, provided at one end of the shaft, carries three notches which are engageable by a spring loaded pin, (37, Fig. 6, not shown), each notch corresponding to one line of action of the cam surfaces and serving to releasably retain the shaft in this position. The inlet 4 and outlet 5 extend perpendicularly to the valve plane thereby allowing valve members to be added or removed. Instead of slide valves, poppet valves may be used, (Fig. 1, not shown), and instead of one, two multiway valves, secured together, may be used to form a control bank, (Fig. 3, not shown). In all cases, the valve may be readily adjusted for controlling one consumer only.

A self-oscillating frequency changer comprises a valve 15 with two or more grids between cathode and anode. Oscillations are generated by connecting the grids together via an inductance 10 and to cathode by way of condensers 12, 13 which may comprise the valve capacities. The signal is applied to a tap on the inductance 10 forming, in conjunction with the capacities 12, 13 a balanced network in which the tapping point is at zero potential at the oscillator frequency. This is varied by conjoint variation of the capacities 12, 13 or by means of a variable condenser 11 shunting the inductance. The network is also resonated at the signal frequency by means of a variable inductance 7 forming the anode circuit of a preceding H.F. amplifier 4; the inductance may alternatively be fixed and shunted with a variable condenser. In another embodiment, Fig. 2 (not shown), the anode of the H.F. stage is connected to earth over a fixed condenser and via an inductance to the tap on the coil 10, H.T. being fed in through a blocking resistance. In this arrangement both oscillator and signal frequency are varied by variation of the capacities 12, 13 which comprise a two-gang condenser; it is stated that in this circuit the correct difference-frequency can be maintained in tuning over a frequency range.

Abstract: 327,796. Nash, R. J. Feb. 4, 1929. Rackets.-In the manufacture of a racket for games the sides of the extremities or the lower portion of the wooden bow frame are shaved off to form inclined plane surfaces and the junction with the handle is made by a succession of unbent wood members overlapping the tapered-down extremities to strengthen the shoulder of the frame. The bow frame a, Fig. 1, which is made of a strip of ash terminating at the throat, is bent to the desired shape with a wedge piece b and a strengthening strip c glued thereto. The sides are shaved down to form inclined surfaces on which are glued Y-shaped overlays d, Fig. 2, made in two parts joined either down the centre line or as shown in dotted lines, and shaved down as shown in Fig. 9. Wedge-shaped overlays e, Fig. 3, are next applied one to the overlay d and the other to a piece of wood h, Fig. 5, forming the handle part, these two parts, after shaping, being then glued together as shown in Fig. 12. The parts are then shaved down ready for the handle slips, the shoulders conforming approximately with the plane of the bow frame. In Figs. 14 and 15 alternate forms of bow frame are shown which avoid reverse bending of the ends of the strip a.
