Patent GB-612624-A (GB)
Title: Improvements in or relating to fuel supply systems for internal combustion engines
IPC: F02C7/236
Filed: 1946-04-01
Abstract: 612,624. Fluid - pressure servomotors. HOOKER, S. G., and BALLANTYNE, D. H. April 1, 1946, No. 10084. [Class 135] [Also in Group XXVII] In a fuel supply system for an internalcombustion engine comprising two or more pumps having regulating means adjusted by a common hydraulic control, means are provided for isolating one or more regulating means from the common control, whereby one or more pumps are rendered inoperative and the rate of delivery of the others is increased. As applied to a jet-propulsion engine, two swashplate pumps 16, 17 delivering through pipes 31 into a common pipe 28 leading to the engine through a throttle valve 29, are controlled by the pressure of fuel on the opposite sides of pistons 34 connected to the angularly adjustable swash-plates 21. The delivery pressure acting on a piston 39 controls a lever 40 pivoted in a diaphragm 14 and controlling a valve 41 allowing fuel to flow through orifices 36 and pipes 44, the pressure drop across the orifices controlling the pistons 34 and hence the pump deliveries. A capsule 43 adjusts the lever 40 according to altitude and the centrifugal pressure set up by the pump rotors 18 acts on diaphragms 47 which open valves 46 above a certain speed, bleeding fuel through the orifices 36 and reducing the pump deliveries. Closing of a manually-operated valve 49 causes an increase of pressure on the right-hand side of piston 34 of pump 17, increasing its delivery. Hence, if pump 16 should fail or its delivery cease due to sticking open of its valve 46 or the valve 41, the pump 17 will maintain the fuel supply on closing of the valve 49. Alternatively, if the pump 17 fails or its valve 46 sticks open, the drop in pressure in pipe 28 closes the valve 41 which causes the delivery of the pump 16 to be increased. Similarly, if the pipe 44<1> is punctured, closure of the valve 49 increases the delivery of pump 17 and the loss of pressure in the pipe 44 of pump 16 reduces its delivery to zero. Non-return valves may be provided in the pipes 44 to prevent a pump which has failed being rotated by fuel from the other pump. A governor may be fitted to each of the pumps so that when either is supplying the engine on its own, its stroke is automatically adjusted to give the maximum permissible speed of the engine.

Abstract: 610,239. Making posts. LOUVROILMONTBARD-AULNOYE. April 2, 1946, No. 10156. Convention date Jan. 18, 1943 [Classes 83 (ii) and 83 (iv)] Rolling tubes ; mandrels.-In a method of making a multi-stepped tubular metal pole, a tube is partially closed at one end to provide a rest for an inner mandrel whose nose is secured thereto by a nut or key after the tube has been heated to a high temperature, and the assembly is then forced into a series of drawing sets with three or four rollers each and having decreasing sections. A tube, partially closed at one end as shown in Fig. 2 is heated in an oven A, Fig. 1, and then passes via a roller track G to a bench B where a head O moving on an endless rope pneumatically actuated, drives a mandrel into the tube up to an abutment H, the projecting screwed nose of the mandrel then being locked to the tube by a nut. The assembled tube and mandrel then falls on to a forcing bench C where the tail of the mandrel is keyed to a head R and forced into the drawing roller sets I by a push-rod S operated through gearing K from a motor M or hydraulically. The drawn tube then falls on to a bench D where the nose of the mandrel is freed and the mandrel pulled out of the tube, and returned by an elevator to the bench B. The mandrel may be stepped to conform with the desired profile of the pole.

Title: Improvements in and relating to therapeutic for deficiency diseases and method of preparing the same
IPC: A61K36/185
Filed: 1933-04-06
Abstract: <PICT:0418214/IV/1> <PICT:0418214/IV/2> A therapeutic preparation containing the vitamins and other remedial constituents of raw fresh plant tissue is obtained by subjecting the plant tissue to mechanical treatment in the presence of added water so as to rupture the individual cells and liberate their contents, and then concentrating the fluid so obtained, preferably after eliminating the cellulose and coagulable protein.  The process is carried out at temperatures endurable by the living plant and without addition of preservative or other chemicals.  According to an example, fresh spinach is rinsed momentarily in hot water and then passed through a series of hammer mills with the addition of water.  Cellulose is removed by passage through a filter press and the filter cake is stirred with water and again filtered.  The combined filtrates are concentrated in vacuo at about 100 DEG  F. and again passed to a filter press to remove coagulated protein.  Preferably, the filter cake is removed and subjected to heavy pressure to obtain an oily liquid, containing vitamin A, which is added to the filtrate.  The filtrate is further concentrated in a vacuum kettle, and then treated, in pans, with dry air at 110 DEG  F. until it forms thick skins.  The skins are removed from the pans and successively dried in a vacuum kettle, comminuted in a hammer mill, treated in a vacuum kettle fitted with stirrer, ground in a ball mill, and formed into tablets in a press.  In modifications of the process the concentration may be stopped when the mixture is in heavy liquid condition; the addition of oily matter expressed from the coagulated protein may be omitted, or vitamin A from some other source may be added in place thereof; or the process may be carried out without removal of cellulose or of protein. Reference has been directed by the Comptroller to Specifications 133,183, and 270,629, (as open to inspection under Sect. 91 of the Acts), [both in Class 49].

Title: Improvements in or relating to load-share responsive devices for paralleled systems of three-phase alternators
Inventor: CHILMAN JOHN ALFRED
IPC: H02J3/46
Filed: 1952-04-24
Abstract: 732,052. Supply systems depending on the use of two or more machines; automatic power control systems. ROTOL, Ltd. April 20, 1953 [April 24, 1952], No. 10358/52. Class 38 (4). A device S for use with parallel-running threephase alternators Al, A2 and responsive to deviation of the load on machine A1 from a predetermined fractional share of the total load taken by the supply lines L1, L2, comprises an induction motor, which may either indicate, or initiate correction of the deviation, having a rotor 12 and a two-phase stator winding 10, 11. Winding 10 is energized by the voltage across two of the alternator phases, say b, c, whilst winding 11 is energized, over current transformers TA1, TL1, TL2, by a voltage proportional to the difference between the total load on the third phase (a) of the supply lines and the load supplied to that phase by machine A1 the transformer ratios being such that the voltage difference is zero (and thus there is no torque on the rotor 12) when the machine A1 is supplying its proper share of the load. Under other conditions a torque tending to rotate the rotor in one direction or the other is developed, which rotation may be utilized to indicate, or correct, departure from correct load division. Fig. 3 shows engines E1-E4 of a multi-engine aircraft each driving a variable pitch airscrew and a three-phase alternator. A load-sharing device 10-12 is provided for each alternator and effects automatic control by acting on a variable datum governor G4 for regulating the pitch of the associated airscrew. Limit switches 27, 28 control indicating lamps 29, 38 for signalling when either end of the control range is reached. The line transformers, such as TA4, associated with each machine are of variable ratio (e.g. tapped) and subsidiary contacts SS4 on the paralleling switch PS4 of-each machine are so arranged to control the ratio of the transformers of the other machines that the load is shared evenly, irrespectively of the number of machines in service. A single synchronizing device PAR, similar to the load-sharing device, but wherein the rotor is spring-biased in one direction and adapted to close a pair of contacts when rotated sufficiently far in the other direction, may be switched to any machine to control the automatic closure of its paralleling switch at an appropriate point in the slip cycle, a device SYN4, as described in Specification 692,866, meanwhile acting on the pitch governor G4 to bring the machine to synchronous speed. A clutch C4 between each engine and alternator is arranged to slip when a predetermined percentage of pull-out torque is exceeded. In the case where the prime-movers are jet engines, the governors G4 control the fuel intake.

Abstract: 1,108,412. Mounting electrical heaters for yarn processing machines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 16 Feb., 1967 [9 March, 1966], No. 10367/66. Heading H5H. [Also in Division D1] Elongated heater blocks 1, 3, are hingedly mounted in their length direction on a support 5 and bear yarn-contacting elements 2, 4, for engaging a yarn Y wrapped around a pulley 11 such that it can reverse its direction through the heater. Pulley 11 is slidably mounted on a rod 13, and a wire 15 is attached above and below pulley 11 and leads to a drum (not shown) driven by a motor, by which drum the the pulley 11 is raised or lowered along rod 13 between pulleys 17, 19. There are double grooves in pulley 11 for a twin thread-line, (Fig. 2, not shown). A cover 21 assists thermal insulation of the heater. The heated yarn-contacting elements 2, 4, are curved, in a manner convex to the yarn path, and are grooved for the yarn to run therein. Two pulleys may be provided and are mounted at each end of the heater blocks to cause the yarn to make more than one reversal of direction through the heater. The pulley grooves are staggered to cause the yarn to be led through the heater along paths inclined to the vertical. The yarn-contacting elements are then curved in a plane parallel to that containing the axes of the pulleys. A false twist crimping machine with the heater therein may have its feed roll and withdrawal roll for the false twist zone grouped in close proximity at one end of the heater. In a combined drawing and friction false-twist crimping process for two nylon 66 yarns, which are twisted respectively " S " and " Z " and then doubled, the heater is used for setting the high twist in the yarns prior to the twist being released on passage through the friction false-twisting device. The invention is applicable to synthetic fibre yarns, e.g. nylon, or to any yarn processing machines which process ready-made yarns, or to draw-twisters and draw-winders which process yarn on the run during its production.
