Title: Improvements in and relating to means for ascertaining and measuring the direction of a magnetic field
IPC: G01R33/02
Filed: 1943-04-29
Abstract: 563,522. Magnetic measurements. HUGHES & SON, Ltd., H., HARRISON, E. P., and HUGHES, A. J. April 29, 1943, No. 6796. [Class 37] Apparatus for ascertaining and measuring the direction of a magnetic field comprises a square alternating current bridge network having wholly magnetic arms, a source of alternating current connected to the network, current measuring instrumentalities connected to said network, and calibrated means for adjusting the median plane of said network relatively to the magnetic axis of the earth. The bridge consists of two parallel pairs of wires 1, 2 ; 3, 4 ; 5, 6 ; and 7, 8 ; the pairs being mounted at right angles to each other in grooves under cover strips o<2> on opposite faces of an insulating disc o. The wires are made of suitably heat-treated samples of a nickel-iron alloy containing small quantities of copper, manganese, chromium and silicon, having high permeability, so as to exhibit large changes in impedance to alternating current due to changes in magnetic field, owing to skin effect. The bridge elements are connected together by low impedance conductors and to a socket x to which is coupled a four-core conductor which connects one pair of opposite corners to a source z of alternating current, and the other pair of corners to a thermionic amplifier u, rectifier v and centre zero micro-ammeter w. The disc o is pivoted at opposite points m to a part circular frame j which is capable of circumferential movement in circular guides under the control of a knob l. The axis m-m is at 45 degrees to the wires. The above apparatus is all supported on a rotatable azimuth circle c supported on levelling screws b. The disc o has a four-armed member p arranged about the upper pivot m which co-operates with a spring pin n so as to lock the disc o in four positions, either in the plane of frame j or at right angles to it. The magnetic meridian is determined by placing the disc o in a vertical plane with the axis m-m making a greater angle with the horizon than the angle of dip. Azimuth readings are taken for the two positions, one each side of the meridian, which give a balance. The mean of these readings gives the meridian. The disc is then placed in the meridian position and the frame j is rotated by knob l to give a balance. The angle of axis m-m with the horizontal is the angle of dip. Each reading is taken twice, the disc o being rotated through 180 degrees on the cradle j and held by the member p. This eliminates inequalities in the bridge arms. The source of supply z is a thermionic oscillator. Suitable circuits for the elements u and v are described, Fig. 11 (not shown).

An aircraft 104 comprising a fuselage 106 and wings 118 has a parachute 134 carried (e.g. under a cover 138 which can pivot open about a transverse axis 140 at its rear end) under the aircraft fuselage, and connected by a rope or strap 126 which extends from the parachute, along the underside of the fuselage, to the rear end thereof, and thence along the top of the fuselage to an anchorage substantially above the aircraft c.g. (e.g. on the roof of the cabin 110). The cover 138 may be opened to allow the parachute to deploy, by the pilot pulling a cord 148 to withdraw a bolt 144 from a bracket 142. The anchorage and the cover 138 may be attached to the fuselage and/or wings by straps 116, 120, 122 of metal and/or woven synthetic fibres, and/or by glue, and/or by bolts (168), Fig. 12 (not shown), engaging captive nuts (182) in the aircraft framework.

Title: Capacitive measuring system with zeroizing means
IPC: G01D18/00
Filed: 1977-02-22
Abstract: The thread (F) is passed through a capacitive sensor (12) which generates a sensor signal in accordance with the changes in the capacitance of the sensor (12). The zero level of the sensor signal can drift due to contamination of the sensor. To allow a reliable absolute-value measurement independent of interruptions of the measurement during the cleaning of the sensor heads, the device is equipped with a compensation arrangement (20) which is used for generating any compensation signal and for combining the signal with the sensor signal to form a composite measurement signal (20a). The compensation arrangement comprises a zero-level control arrangement which switches on when the thread (F) is removed from the sensor (12) in order to return the level of the composite measurement signal (20a) to a particular nominal value independent of the degree of contamination of the sensor. <IMAGE>

Title: Improvements in heating installations
IPC: F24H9/12
Filed: 1927-03-19
Abstract: 292,662. Srulowitz, H., Friedmann, L., Friedmann, M., and Schopp, N., (trading as Friedmann, A., [Firm of]). March 19, 1927. Heating buildings. - The steam supply to radiators 10 is controlled by an expanding tube 4 subject to radiation, which actuates a valve 3 through a rod b to control the pressure in a chamber 7 which supplies the radiators, the pressure regulating means being dependent, on the room temperature. The steam from the chamber 7 passes through an auxiliary radiator 5 enclosing the expanding rod 4 which controls the admission port 2. The temperature is determined by a preliminary adjustment of the rod 4 by means of lever 6. In a modification, (Fig. 2, not shown), the temperature is determined by the adjustment of a valve in the opening 9, Fig. 1. In another modification, the tube 4, Fig. 4, is hollow for the passage of steam, and a valve 15 is provided controlling the ports 8, 9, 16. When the opening 9 is closed and 16 open, steam passes through the tube 4, thus expanding it and closing the admission valve. In another modification, (Fig. 9, not shown), the admission ports to the tube 4 are in the chamber 7, and the temperature is determined by a valve in the cutlet of the chamber 7. In another modification, (Fig. 10, not shown), either the admission pressuremay be regulated as above, or the regulation may be effected by the exhaust steam in known manner. A number of radiators may be connected to the chamber 7 of which only one or two may be connected with the auxiliary radiator 5. In Fig. 13, a casing carrying the thermostatic device 4, 5 is inserted between the admission and exhaust of a radiator element in the form of a loop. Steam is supplied through pipe 1 to. chamber 32 and thence through port 2 to chamber 7. This chamber is connected to the radiator through a. lateral opening controlled by a hand-operated slide valve. The valve member 29 consists of a short tubular piece within the end 30 of the expansion tube 4, and pressed outwards by a spring which prevents damage on over-expansion of the tube 4. Steam is admitted to the tube through openings 8a just behind the closure member, and openings 8 are also provided communicating with the exhaust chamber 26. When heating is started, the slide valve is opened and steam passes through chamber 7 to the radiators. This exerts a suction on the openings 8<a>, and steam passes from the radiator exhaust outward through tube 5 and inward through tube 4 so that the thermostatic valve is controlled by exhaust steam in known manner. The admission valve is then partly closed, and pressure increases in chamber 7, so that steam flows in the reverse direction through tube 4 which thereby controls the pressure in the admission chamber 7 as in previous modifications. Another modification (Figs. 16 - - 22, not shown), is described in which the openings 8 are controlled by the hand-operated slide valve.
