Title: Improvements in and relating to apparatus for controlling the supply of liquid fuel to containers
IPC: B64F1/28
Filed: 1960-12-02
Abstract: 908,435. Dispensing liquid fuel. REGULATOR A.G. Dec. 2, 1960 [Dec. 4, 1959], No. 41644/60. Class 116. [Also in Group XXIX] In apparatus for supplying fuel to tanks, e.g. aircraft fuel tanks, a container 31, Fig. 1, is connected to the fuel supply line 15 through a conduit 29 containing a non-return valve unit 35 which is adapted to open only when the pressure in the conduit 29 exceeds a predetermined value to allow fuel to flow into the container 31 to relieve the pressure in the fuel tanks. The fuel is supplied from a storage tank (not shown) through a feeder line 11 and a shut-off valve 13 to the line 15, which is provided with a fuel filler 17, a valve 19 for controlling the fuel pressure, and manometers 21, 23, 25. The valve unit 35 comprises a combination of three spring-loaded relief valves connected in parallel and operable at different fuel pressures. The three valve members 51, 53, Fig. 2, and 55 (not shown), are pressed to closed positions by springs 57, 75, and 81, of progressively increasing strength, the spring pressures being adjustable by turning threaded sleeves 63, 77, and 83 (not shown). The valve members 51, 53 may be locked in closed position by hydraulic pressure applied through conduits 67, 79 to pistons 61. The valve 19 and the valve unit 35 are adjustable by an hydraulic remote-control means having an operating handle 113 on a shaft 115 carrying cams 117, 119. When the handle 113 is set to the I position valves 121, 123 are actuated by the cams 117, 119 to adjust valve 19 to reduce the fuel pressure to the lowest of three chosen valves, and to unlock the valve member 51. When the handle 113 is set to the II position the valve 121 is set to adjust the valve 19 for an intermediate fuel pressure and to lock the valve member 51 in the closed position whilst leaving the valve member 53 unlocked. In the III position of the handle 113, both valve members 51, 53 are locked in their closed positions, and the valve 19 is adjusted for maximum fuel pressure. The valve 13 is also remote controlled, its valve member 135 being adapted to be held closed by fuel pressure applied through a conduit 139 and controlled by a valve 141. A pivoted lever 151 is operable to actuate the valve 141 to allow the valve 13 to open only when a projection 155 on the lever can engage in one of three notches in a disc 153 on the shaft 115, i.e. when the handle 113 is in the I, II or III position. The construction of the valve 19 is described in detail (see Group XXIX).

Abstract: 916,866. Purifying waste brine from mercury cathode cells. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 20, 1961 [Dec. 15, 1960], No. 43215/60. Class 41. Waste brine from electrolytic cells using a mercury cathode and containing chlorine and traces of mercury is purified and freed from mercury before recharging with brine, in two stages, (1) adding sulphide ions preferably as sodium hydro-sulphide in controlled amount until the redox potential measured against a KCl/HgCl cell is 0.85 to 0.93 v., (2) raising the pH to 7 to 8 and adding more sulphide until the redox potential is 0 to 0.2 v. Mercury sulphide is formed and is flocculated and removed as a precipitate, e.g. by adding a flocculating agent. For example, waste brine is blown with air to remove most of the chlorine, and then had a redox potential of 1.06 v. relative to a saturated KCl/HgCl cell, and a pH of 3. Sodium hydrosulphide liquor is then added until the potential falls to 0.85. Lime water is then added to raise the pH value to 8.5, the potential being then 0.3 v., whereupon more alkali hydrosulphide is added, reducing the potential to 0.2 v. A flocculating agent is added and the liquid slowly stirred, and after settling is filtered. Mercury content is reduced from 4 p.p.m. to 0.1 p.p.m.

Filed: 1975-10-24
Abstract: The fibre material, for example waste paper, is introduced into a rotating drum (1) which has a perforated shell (4) provided on the inside with longitudinal fins (7), but no tearing or cutting tools whatsoever. Through a feed line (8), fluid is passed into the drum (1) so that the fibre material is wetted and remains in a wet state. When the drum (1) rotates, the fibre material is periodically lifted by means of each of the longitudinal fins and then dropped back from the upper part of the drum (1) onto the drum bottom. As a result, the material is defibrated and divided into a fine fraction and coarse fraction. The fine fraction passes through the perforation, and the coarse fraction is discharged through an orifice in one end wall of the drum (1). Any foreign bodies present in the fibre material can readily be separated out in this way. <IMAGE>

Abstract: 951,185. Semi-conductor pulse circuits. AMP Inc. Nov. 22, 1962 [Dec. 4, 1961], No. 44141/62. Heading H3T. A circuit for feeding pulses in succession to two loads 34, 35 comprises a pair of four-layer diodes 5<SP>1</SP> ,  6<SP>1</SP> rendered conductive alternately by pulses from sources 71, 10<SP>1</SP>, arrangements being made to ensure that the voltage across each diode is constant when the other is conductive. Circuits are described for energizing a multi-aperture magnetic core shift register 33 of the type described in Specification 899,366. Four-layer diode 6<SP>1</SP> is first made conductive by a pulse from source 10<SP>1</SP>, charging capacitor 20<SP>1</SP> from a source 13<SP>1</SP> via diodes 15<SP>1</SP>, 27<SP>1</SP>, 321 and winding 35. The voltage to which capacitor 20<SP>1</SP> is charged is increased by the effect of inductor 231. A current pulse is thus produced in winding 35. Capacitor 201 retains its charge until a pulse from 7<SP>1</SP> turns on diode 5<SP>1</SP> which discharges capacitor 20<SP>1</SP> via diode 31<SP>1</SP>, inductor 22<SP>1</SP>, diode 21<SP>1</SP> and winding 34, thus providing a current pulse in winding 34. The voltage across diode 5<SP>1</SP> is kept constant by resistor 14<SP>1</SP> when diode 6<SP>1</SP> is conductive. The voltage across diode 6<SP>1</SP> is kept constant when diode 5<SP>1</SP> is conductive by the action of diodes 21<SP>1</SP>, 39 and capacitor 38. Specification 943,070 also is referred to.
