Patent GB-1045432-A (GB)
Title: Improvements in and relating to the manufacture of ferrimagnetic materials
IPC: H01F1/11
Filed: 1964-02-20
Abstract: A process for manufacturing a ferrimagnetic material in the form of sintered finely divided particles comprises converting at least one salt of a divalent metal and at least one salt of a trivalent iron, in the presence of an epoxy compound and a source of hydroxyl groups, to a sol containing a mixture of the corresponding hydroxides which is then converted into the desired ferrimagnetic material by heating. The salts may be chlorides, bromides or iodides, and the divalent metal may be cobalt.  The sol is converted into a gel and the other reaction products are driven off before the mixture is heated to form the ferrimagnetic matetial.  The ferrimagnetic particles of the invention may be coated with an antiferromagnetic material for example a Fe2O3, coupled by exchange anisotropy (that is to say, the spin systems of the ferrimagnetic and antiferromagnetic phases are coupled) which gives material with a higher coercivity than the ferrimagnetic material above.  The product of the Microgel process has pores smaller than 1000 <\>rA diameter and surface areas above 2 m.2/gram.  Because of this porosity it can be ground more easily than the products of conventional processes.  The epoxy compound may be a lower alkylene oxide (ethylene, propylene or butylene oxide) or an epichlorohydrin, and the source of hydroxyl groups may be water.  A polar solvent (water or a lower alkanol) which is more polar than the epoxy compound may be present.  The ferrimagnetic materials produced may have spinel, garnet, magneto-plumbite or perovskite structure. To give particles with an insulating coating the gel produced above is ground with aluminium chloride (for a coating of Al2O3) and a lower alkanol.  A lower alkylene oxide is then added resulting in a dispersion of the ferrimagnetic precursor particles in an Al(OH)3 gel. Heating yields ferrimagnetic particles coated with Al2O3. Silica, magnesia, or zirconia may be used instead of alumina.

Abstract: 1,022,162. Fuel injection pumps. C.A.V. Ltd. May 22, 1963 [Feb. 26, 1962], No. 7333/62. Heading F1A. In a fuel injection pump having a rotary distributer, each fuel line from the distributor includes a cylindrical chamber in which is fitted a valve member, the valve member being opened during the injection stroke by fuel pressure and on its return movement it urges fuel back towards the pump. The valve member may be a ball 25 or a plunger 18 (Fig. 1 not shown). During the injection stroke the ball 25 rises and forces out fuel through a hole 24 until the hole 23 is uncovered. The ball urges fuel back on its return when the hole 23 is covered thereby reducing the likelihood of cavitation. In alternative embodiments the seat 26 may be omitted and the holes 23, 24 replaced by one hole large enough to permit fuel to flow from the pump while preventing the ball from being hydraulically locked in the bore. Alternatively a bolt 20 may have the passage 19 extending throughout its length (Fig. 5, not shown) when the recess of greater diameter than the ball is formed in the chamber.

Title: Improvements in or relating to gas-driven power supply systems
Inventor: MUIRHEAD GEORGE JOHN
IPC: F16K31/42
Filed: 1956-03-08
Abstract: 855,510. Turbines. ENGLISH ELECTRIC CO. Ltd. March 5, 1957 [March 8, 1956], No. 7362/56. Class 110 (3). [Also in Groups XXIX and XXXV] A gas-driven power supply system comprises solid gas-producing charge means, a gas-driven turbine, a control-valve between the charge means and the turbine, and automatic control means operative to fully open the valve when the power output falls below a predetermined value and to fully close the valve when the power output increasesabove a second predetermined value. The invention is described as applied to a turbine driven by gas produced by a cordite charge. Such a turbine may be used in a guided missile for supplying electrical and hydraulic power. Fig. 1 illustrates a cordite charge 12 with a relief valve 18 feeding a turbine 11 driving an hydraulic pump and a turbine 10 driving an alternator, each turbine having a control valve 16, 13 with an associated hydraulic actuator 17, 14. The voltage output of the alternator is tapped and fed to an amplifier 15 (see Group XXXV) incorporating a switch, whereby a solenoid 22a, Fig. 2, is energized and de-energized in accordance with variations of output of the alternator. When the solenoid is de-energized a spool valve 21c is depressed by a loading-spring 22c to vent a chamber 21d so that the turbine control valve 20c is opened by gas pressure in the inlet 20a. Energization of the solenoid causes the spool valve to direct pressure fluid to the chamber 21d to cause a plunger 21e to close the valve 20c. To minimize heat transfer from the housing of the valve 20c to the hydraulic system the valve housing and the housing 21 for the hydraulic system are separated by slim supports 23. A shield 20f protects the sliding parts of the valve 20c from solid particles in the gas.

Filed: 1951-03-30
Abstract: 695,995. Jet propulsion plant. ARMSTRONG SIDDELEY MOTORS, Ltd. Feb. 15, 1952 [March 30, 1951], No. 7377/51. Class 110(iii) A rocket control system comprising at least one valve or other control part which is operated by a high fluid pressure but which does not require a continuous flow and at least one other part which is supplied at a low fluid pressure and requires a continuous flow, the fluid pressure being supplied from at least two very high pressure receptacles through appropriate reducing valves, has a pressure responsive reserve valve interconnecting the inlets of the pressure reducing valves which only close when the pressure in the receptacles falls to a predetermined .value. A high pressure supply line 14 and a low pressure supply line 15 are supplied from very high pressure receptacles 11, 11a through reducing valves 13. The receptacles 11, 11a are charged through a valve 18 and a non- return valve 17. Pipe lines 24, 25 and valve 20 interconnect the inlets of the reducing valves 13. The valve 20, Fig. 3, comprises a valve member 21 which is forced by a spring 22 on to a seating 23 but remains open so long as the pressure in the pipes 24, 25 exceeds a predetermined value. When the pressure in the receptacles falls below this value the valve 20 closes and the receptacle 11 is cut off from the low pressure line 15 except for the connection through the non-return valve 17. The pressure in the high pressure line 14 falls at a slower rate than in the low pressure line 15 so that the non-return valve 17 soon closes and completely cuts off the line 15 from the receptacle 11. The receptacle 11 a may be replaced by two or more smaller receptacles.

Title: Improvements in and relating to apparatus for feeding ream markers to sheets cut from paper and like webs
IPC: B65H33/04
Filed: 1949-03-18
Abstract: 657,868. Delivery sheets ; feeding webs. BATTERSBY, J. E., and MASSON, SCOTT & CO., Ltd. March 18, 1949, No. 7452. [Class 100 (i)] In an apparatus for feeding ream markers to sheets cut from webs of the kind in which the marker web is drawn from a reel by intermittently-operated means and fed to a rotary sheet-cutter so that the required length of marker web is severed together with the desired sheet or sheets as determined by counter mechanism, means are provided for retracting a sufficient length of marker web after the marker feeding means has ceased to operate to compensate for any subsequent advance of the web due to over-running of the marker reel. The marker web 11 is drawn from a reel 1 by rollers 17 and 21 and fed through a guide 23 to a rotary sheet-cutter 24. The roller 17 is normally spaced from the driving roller 21, but is brought into engagement with the latter by a solenoid 20 which is energized at the appropriate time and deenergized after an interval sufficient for feeding the desired length of marker web. The increase in tension of the web 11 during feeding causes anticlockwise rotation of a lever 8, carrying guide rolls 10, about a pivot 9 such that a spring 15 on a rod 12 is compressed by an arm 14. Compression of the spring 15 overcomes the tension of a spring 13, thus releasing an internally-expanding brake -6 to allow the reel to rotate. Subsequent decrease in tension of the web 11 during non-feeding allows the arm 8 to rotate under the action of the spring 15 in a clockwise direction and thus retract a length of web. Specification 611,978 is referred to.

Abstract: 540,155. Closuring containers. CLARKE, D. H. April 27, 1940, No. 7585. [Class 125 (ii)] [Also in. Group, XXII] Mechanism for assembling lids and preserving containers, bottles, jars, or other bodies, and presenting them to vacuum or gas-filled sealing mechanism comprises a disc K arranged for intermittent rotation in air-tight contact with the lower face of a stationary vacuum chamber A containing the sealing mechanism B, the disc having two or more holes through which unsealed bodies are presented in turn to the mechanism B. A pile of lids H is placed in a hole of a disc U in one with the chamber A, the lower disc resting in a recess of the aligned hole in the plate K. A body E is placed by hand or mechanism on a support F carried by a shaft M mounted to slide axially but not rotate in holes of a support N fixed on a shaft Q on which the disc K and a disc O, for supporting chambers L are also fixed. The shaft is then rotated by gearing S, T through say 90 degrees to bring the next support into position to receive a fresh body, and the body E and adjacent lid to a position below an evacuating pipe X. A lever W<SP>2</SP> is then moved to position W, to lift the chamber L into air-tight contact with the disc K. The chamber L is then evacuated and thus supported from the disc K during the next movement which brings the chamber into position L<SP>1</SP> where the body and lid are raised to engage the clutch C by the support F, shaft M, and lever V. After sealing, the lever V and parts supported thereby are lowered, the lid now having a reduced diameter, passing with body through the hole in the plate K. During the next movement of the shaft Q the vacuum in the chamber L is relieved so that it falls into its lower position and the sealed container can be removed. A vacuum or a desired gas under reduced pressure is maintained in the chamber A by a pipe G, the chamber L being retained in its upper position by known mechanical means, if necessary, in the latter case.

Title: A device for controlling gear ratio changing
Inventor: FALCIAI FABRIZIO

Filed: 1971-03-26
Abstract: 1,244,140. Regulating I.C. engines; spray carburetters. F. FALCIAI, R. FALCIAI and R. FALCIAI. Aug.10, 1968 [Aug. 12, 1967], No.7897/71. Divided out of 1, 243, 395. Heading F1B. [Also in Division F2] A gear ratio servocontrol associated with an internal combustion engine is operated by a membrane 12 of a container 11 connected to a valve device 7 which includes a plate 6 normally biased to a position transverse of a carburetter-engine conduit 4. In this position of the plate, a toothed rod 18, 19, due to arms 22, 25 is disengaged from a toothed segment 17 and a valve 15 is biased, by a spring 16, to close an auxiliary conduit 5. If the engine is running at high speed and the throttle valve 3 is suddenly closed the reduction in pressure in the conduit 4 causes the membrane 12 to contract and the gear ratio to decrease. Air admitted through a valve 14 and mixed with petrol from the carburetter in its idling position is sufficient to keep the plate 6 out of its transverse position but, as the engine slows, the flow through the conduit 4 is reduced and the plate 6 moves to its transverse position. The container 11 is thus connected to atmosphere via a passage 9, the membrane 12 expands and the gear ratio increases until there is no output drive when the engine is idling. When it is desired to use the engine as a brake, the rod 19, which may be operated by the foot brake pedal during the first portion of its travel, is moved downwardly and the valve 15 admits air to the conduit 4 from the conduit 5. This flow causes clockwise rotation of the plate 6 so that the gear ratio is increased to a value higher than would otherwise be the case. When the engine is running at low speed, impoverishment of the mixture is avoided by the valve 15 being allowed to close, the movement of the plate 6 towards its transverse position causing disengagement of the teeth 17, 18. The servocontrol may be disconnected from the automatic control and actuated directly by an operator.
