Title: Improvements relating to the control, stability and ventilation of rigid airships
IPC: B64B1/40
Filed: 1923-11-06
Abstract: 225,353. Richmond, V. C., and Scott, G. H. Nov. 6, 1923. Aerostats; steering. - For steering, stabilizing and ventilating airships, the aerostat is provided with air conduits F<1> - - F<4> each leading from the area of greatest pressure near the nose to the area of least pressure near the tail on the same side of the longitudinal axis of the airship, the resulting air currents being directed outwardly in vertical and horizontal directions at the rear of the airship. By closing one or other of the conduits, elevating and steering reactions are obtained, and any external disturbance causing the airship to yaw alters the distribution of pressure at the nose and the resulting variation of the air currents in the conduits automatically tends to correct the deviation. Instead, of four symmetrically arranged conduits, two conduits having respectively vertical and horizontal discharge orifices may be employed and means provided for closing theorifices to a greater or less extent.. Ventilation of the space between the gas bags and the outer covering is effected by induction by connecting this space to the conduits, for example the space in the top quadrant can be connected to the conduit in that quadrant.

Title: Two-way communication system
IPC: H04B1/68
Filed: 1952-11-07
Abstract: 715,452. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd. Nov. 7, 1952 [Nov. 28, 1951], No. 28062/52. Class 40 (4) [Also in Group XL (c)] In a two-way electrical communication system employing two terminal stations and one or more repeater stations the signalling time at each station is divided into regularly recurring groups of three equal time periods T/3 during one of which the station receiver is blocked so that although the repeaters transmit both ways simultaneously the reception back at a station which has previously transmitted a signal is prevented by the receiver having meanwhile become blocked. Further, during the unblocked period of each repeater station receiver the transmissions are received alternately from opposite directions for retransmission onwards. To this end the stations may be separated by a distance corresponding to an odd and even multiple alternately of the period T/6 in which case the received signals are transmitted straight through without time delay, but if this exact spacing is not complied with, then delay devices are necessary at each repeater for delaying the signal to be retransmitted. As shown, Fig. 1, multiplex pulse signals are transmitted each way between a West and East terminal via repeaters, different frequencies f1, f2, being used alternately, and the timing sequence at each station being controlled by marker pulses from West terminal. At repeater A signals are received alternately from opposite directions by the receiving aerial 24 and retransmitted both ways from aerial 25, 26 by transmitter 20 after a delay determined by the device 23 between the receiver and transmitter. No marker pulses are necessary for Westward transmissions and they may be replaced by a communication channel. The receiver 19 is cut off by a blanking unit 22 for a period T/3 following the period 2T/3 for reception of signals. A common aerial may be used for reception and transmission. The system may also be applied to a coaxial line communication system or to a waveguide system having the receivers and transmitters coupled to it by magic T couplers, or to a line above ground conductor system as described in Specification 704,050, [Group XL (b)]. Specifications 574,627, [Group XL], 600,052, 600,258, 635,482 and 638,371, [Group XL(c)], also are referred to.

Title: Process for the production of fluorine compounds of uranium
Inventor: LEVEL ALBERT
IPC: C01G43/00
Filed: 1959-08-18
Abstract: Uranium fluoride derivatives of general formula (UF4)(RFv)n, where R is an alkali metal, alkaline earth metal, magnesium, or lead, V is the valency of R, and n is the atomic ratio R:U in the uranate, are prepared by subjecting a uranate of R to the simultaneous or successive action of a reducing agent and hydrofluoric acid, so that complete reduction of hexavalent to tetravalent uranium is effected, together with maximum fluoridation of the starting uranate.  The reduction is preferably carried out at 250 DEG  C. to 850 DEG  C. for example with hydrogen, carbon monoxide, methane, lighting gas, or ammonia, and the fluoridation at 300 DEG  C. to 800 DEG  C., preferably with anhydrous hydrogen fluoride.  The reactions may be carried out in fixed or fluidized beds, in which latter case the solid particles are preferably between 75 and 400 microns.  The fluoridation may be carried out in two stages, by firstly partially fluoridizing at below 400 DEG  C., then optionally scavenging with nitrogen or hydrogen, and then completing the fluoridation at above 500 DEG  C.  The fluoride derivative may be converted to uranium hexafluoride or to metallic uranium in known manner.  Examples show the treatment of sodium, calcium, and magnesium manates.

Title: Magnetic field stabilizing method and apparatus
IPC: G01R33/389
Filed: 1957-09-06
Abstract: 868,056. Automatic magnetic field strength control systems. VARIAN ASSOCIATES. Sept. 6, 1957 [Sept. 18, 1956], No. 28260/57. Class 38 (4). In a system for automatically stabilizing a unidirectional magnetic field between the polefaces of a magnet, a current generated in a pickup coil detecting changes in the magnetic field is integrated and applied to control the energization of a coil influencing the magnetic field. In Fig. 2 a magnetic field for a magnetic resonance spectroscope is produced by electromagnets 11 and 12 energized from a D.C. source 15. Coils (not shown) in a probe 26 of the crossedcoil type are associated with the radio-frequency transmitter and receiver and the audio frequency sweep generator of the spectroscope. During normal operation a switch 33 is in its upper position so that voltages induced in interconnected coils 17, 18, 19 upon changes in magnetic field strength are applied to the coil 32 of a mirror galvanometer to upset the even distribution of light between photo-cells 47, 48 so that an amplifier 42 produces an output which energizes interconnected coils 16, 20, 21 to restore the magnetic field strength to the desired value. A portion of the output of amplifier 42, developed across a variable resistance 51, is applied through a low-pass filter (not shown) to control D.C. source 15 and thus provide further correction for slow changes in the magnetic field strength. Magnetic field disturbances are indicated on a meter 43 which may be replaced by a recorder. Methods of discovering the best interconnection, positioning or shunting of the coils are described. The strength of the magnetic field which is automatically maintained is selected manually by adjusting a potentiometer 53 controlling D.C. source 15 and simultaneously operating a generator 56 to apply a voltage to galvanometer coil 32 to prevent correction of the manual change by the automatic control system. A switch 65 may be operated to apply a voltage from a potentiometer 63 or 64 to galvanometer coil 32 so that a sweep of magnetic field strength is produced in either sense from the normal value. Continuous sweeping may be produced by clock operation of switch 65. Zero setting of the galvanometer is facilitated by setting switch 33 to its lower position to shunt the coil and the galvanometer may be balanced by setting switch 33 to the position shown and operating a generator 69 manually.
