Title: Improvements in and relating to electric discharge lamps
IPC: H01J61/30
Filed: 1944-12-21
Abstract: 590,705. Discharge lamps. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., JENKINS, H. G., and SIMMS, C. H. Dec. 21, 1944, No. 25634. [Class 39 (i)] [Also in Group XXIII] A method of constructing an electric discharge lamp of the type wherein the discharge passage is spiral, comprises fusing a strip of glass 11 on to a glass disc 10 to form a spiral channel as shown in Fig. 1. Tubulations 13 and 14 in which electrodes may be housed are sealed to disc 10 to provide connections to the ends of the channel. A second glass disc 15 is then sealed to this component by collapsing it on to the ridge 11, by general heating, or by local and progressive melting by a small flame along ridge 11, to form a closed spiral passage between the tubulations. One end is closed and air is blown into the other while the glass is made plastic by heating, to expand the passage as shown in Fig. 3 during which operation components 10 and 15 may be within a mould. In an alternative form, the components may be of cylindrical shape with domed ends as in Figs. 4 and 5 (not shown). Luminescent material may be applied to the inner surface of the passage as described in Specification 460,756.

Title: Improvements in and relating to automatic control systems for aircraft
Inventor: KRAMER KEVIN CALVIN
IPC: G05D1/06
Filed: 1966-06-09
Abstract: 1,131,732. Automatic control of aircraft. LEAR SIEGLER Inc. June 9, 1966 [June 14, 1965], No.25663/66. Heading G3R. Aircraft elevators are normally controlled by signals dependent on pitch, rate of pitch, and vertical velocity combined with negative feedback signals applied through slowly operating means which are utilized to apply further control signals to the elevators when automatic descent is desired. In Fig. 1, during normal flight of an aircraft, pitch attitude is stabilized by electrical signals from a pitch attitude detector, a rate of pitch gyro 33, and a vertical velocity detector 30, which are combined, filtered, amplified, and applied at 24 to the elevator channel of the aircraft automatic pilot. The vertical velocity signals may be derived from signals produced by a barometric device and signals obtained by integrating the output of a vertical accelerometer. Negative feedback is provided through a unit 26 which includes a velocity servomotor operating a feedback potentiometer. When an automatic descent is desired, switches such as 37, 38 are changed over so that signals from a glide path receiver 34 are applied to the elevator channel through unit 26 which operates as an integrator with a limited rate of change for automatically maintaining the aircraft on the glide path. A unit 36 also includes a velocity servomotor operating a potentiometer which is driven to a position corresponding to that of a preset potentiometer 46 in readiness for application to the elevator channel through integrator 26 to alter the pitch attitude for descent. Thereafter, this second velocity servomotor is converted to an integrator which adds an integral component of control to the glide path error signal. The sensitivity of control by the glide path error signal is automatically reduced below a predetermined altitude, by a potentiometer adjusted in dependence on signals from a radio altimeter 90, until, at a lower predetermined altitude, the signal is reduced to zero. Thereafter a further potentiometer operated by the altimeter progressively reduces the rate of descent as the runway is approached. A switch 18, operated by a control 19 for opening the throttles, applies a signal from a source 20 to the elevator channel to raise the aircraft for a "go-around" in emergency.
Patent GB-410388-A (GB)
Title: Improvements in or relating to circuit arrangements for transmitting high or intermediate frequency oscillations by way of low-frequency multiphase networks
IPC: H04B3/56
Filed: 1933-09-18
Abstract: 410,388. Wired wireless systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Sept. 18, 1933, No. 25771. Convention date, Oct. 20, 1932. [Class 40 (v).] In a polyphase power system, attenuation of superimposed high-frequency currents is ordinarily caused by the loads which form part of the power system ; and according to the invention this attenuation is diminished by a suitable arrangement of circuits. When the power loads are connected between phase wires and a neutral return, the high-frequency currents from a transmitter Z are carried by a pair of phase wires such as 1, 2, Fig. 2 ; and vice versa. The carrier-receiving apparatus, however, is connected to the same leads as the power load, so that only two conductors need enter a house ; hence where in a neutral-return power system one phase wire, such as 1, enters a house together with the neutral wire 0, the high-frequency signal has to be transferred to the house pair 0, 1 by means of a transformer T2. Similarly in a system in which the power loads are connected mainly between phases, the signals are carried by one of the phase wires and a fourth conductor which may be a cable sheath. They are in that case transferred, by means of an auto-transformer or otherwise, (Fig. 3, not shown), to a pair of phase wires for entry into a house.

Title: System for Subsurface Control of the Flow of Fluids through a Well Bore
IPC: E21B34/10
Filed: 1966-06-10
Abstract: 1,151,511. Wells. OTIS ENG. CORP. 10 June, 1966 [14 July, 1965], No. 26088/66. Heading E1F. Apparatus for the subsurface control of fluid flow through a well bore comprises means within the bore defining first and second flow channels and supporting two valves controlling flow through the respective channels, the valves being insertable and removable without disturbing the channels, and means for conducting pressure fluid from the surface to control the valves. In Fig. 1, a control assembly 50 is located within the well casing 53 by a packer 52, and the first flow channel consists of tubing string 65, tubular member 71, valve 60, and tubing string 54. The second flow channel consists of the annular channel 62a, apertures 72, housing 73, valve 61, window 72, and the annular channel 62. A further packer below packer 52 may separate two producing formations of the well. The control fluid, at a pressure determined by a controller 64, is fed by conduit 63 to bores in the assembly 50, to act upon pistons controlling the valve members. Four alternative valves are described, all having spring collet fingers cooperating with annular recesses in bores in the assembly 50 to locate the valves. A plug valve (Fig. 12, not shown) has a cage containing opposed non-return ball valves preventing flow in either direction. A prong on the running tool holds one ball valve open to enable fluid to pass through the valve during installation, and the cage can be displaced to an inoperative position on shearing of a washer by a pulling tool to permit withdrawal of the valve. The producing valve 60 consists of a spherical member with a bore therethrough for well. fluid flow, the member being rotatable to control flow by an annular piston subjected to a spring and to the pressure in conduit 63, Fig. 4-B (not shown). The valve 61 or an alternative completion valve, Fig. 12 (not shown) are installed by a running tool in two articulated parts connected by an unstable sprung linkage such that the tool deforms while passing down string 54 so as to locate the valve in the required bore, Fig. 16 (not shown). The conduit 63 terminates at each end in a plug having sprung collet fingers so that it can be installed in or withdrawn from the assembly 50 and a well head fitting without disturbing the assembly or tubing strings. As an alternative to conduit 63, control pressure fluid may be led to assembly 50 by an annular. flow path provided by a tubing string surrounding string 54, Fig. 32 (not shown).

[Class 38 (iv)] Steering; altitude.-When an aeroplane in which ailerons are controlled by a gyroscopic horizon with pendulum-controlled restoring means is put into a curve the said restoring means are disconnected. The ailerons are then controlled by a pendulum or other device responsive to lateral accelerations or to deviations from the apparent vertical. A switch 2, for example, controlling the direction and speed of a course adjusting motor 3, when operated to initiate curved flight energizes a switch coil 32 to interrupt the control circuit between a gyroscopic horizon instrument 5 and coils 15 of a rotary magnet 16, and to connect coils 30 thereof to a pendulum device 22 instead; the circuit of a pendulum control 17 supervising the transverse, axis of the gyroscope is also interrupted. The rotary magnet 16 operates the control valve of a servomotor adjusting the ailerons. The system shown comprises a bolometer 14 and diaphragm 12 operated in,accordance with tilting of the aircraft about its longitudinal axis to disturb its normal balance, and a bolometer 29 and diaphragm 27, this diaphragm being rendered sensitive to small transverse accelerations of the craft by a geared connection to a heavy pendulum 22 restrained by stiff springs 23 so that it has a high natural frequency. The device 22 may be replaced by a normal pendulum or an instrument jointly responsive to speed of rotation and speed of flight and deriving therefrom the angle between apparent and true verticals as described in Specification 515,072. The invention is applicable with suitable modifications of the switching means, to controls operated by a fluid pressure medium.
