Title: Improvements in or relating to systems for indicating a variable condition of an aircraft
IPC: B64D45/00
Filed: 1958-05-05
Abstract: 840,139. Visible-signalling apparatus. SPECIALITIES Inc. May 5, 1958 [May 6, 1957], No. 14337/58. Class 118 (2). [Also in Group XXXIII] An indicator for use in an aircraft comprises a group of closely-spaced light sources so arranged that under normal flight conditions they are in the pilot's secondary field of vision, means being provided for exciting a selected one or ones of the sources in accordance with a flight condition of the aircraft. In the preferred embodiment the indicator provides an indication of airstream direction in a vertical plane and hence of the angle of attack of the aircraft. The indicator may alternatively be used as a side-slip indicator. In the arrangement illustrated the shaft of the instrument 10 measuring airstream direction operates through a follow-up system comprising potentiometers 13, 17, relays 15, 16 and motor 14 to position a shaft 24 in accordance with the angle of attack of the aircraft. Cams 20, 21, 22, 23 mounted on the shaft determine the conditions of four double-pole switches in accordance with the shaft position and hence the energization of the light sources 34, 35, 36 of the indicator 37. When the angle of attack has the desired value the source 35 is lit; when it is slightly too high both 34 and 35 are lit while when it is much too high only 35 is lit. Similarly when the angle is too low either 35 and 36 or 36 alone are lit. The indicator 37 is arranged behind the windscreen on the ledge above the instrument panel to one side of the pilot's normal field of view. It may be pivotally mounted and the form of the indications provided may be modified to show letters such as " H," " L " or " S," " F " instead of the converging-line patterns shown in the Figure. Further lamps 43, 44, and 45 may be arranged on the leading edge of the aircraft wing to give an indication to ground personnel of the aircraft's angle of attack. In this case, however, only three conditions are indicated, each lamp lighting singly with no provision being made for their lighting in combination.

Title: Process for the extraction of mucilages from seeds
IPC: C08B37/14
Filed: 1953-05-27
Abstract: In extracting mucilages from seeds, e.g. the seeds of Ceratonia siliqua (locust), Cyanopsis tetragonologous, Tamarindus indica, Cesalpinia spinosa, Cesalpinia tinctoria, Cassia and Plantago psyllium, the seeds are soaked in a liquid which expands on freezing, such as water or an aqueous solution having a pH value between 1 and 13.5 and cooled to freeze the liquid and detach the mucilage-containing endosperms, which are then separated from the husks and embryos.  The isolated endosperms may be dried and ground in roll-mills.  Alternatively, the unsoaked seeds are ground, e.g. in a hammer-mill, to reduce the embryos to a fine powder and the endosperms into larger fragments having husks clinging to them.  The powder is separated from the larger fragments, which are then soaked and frozen to detach the husks. The liquid may contain one or more of the following substances: sodium chloride, sodium carbonate, sodium bicarbonate, sodium fluoride, potassium bicarbonate, ammonia, sulphuric acid, sulphur dioxide, soluble albumin, a tetralkyl ammonium compound, alcohol, glycerine, ethylene glycol, formaldehyde, a substituted phenol, butyl-naphthalene sulphonate.  The seeds may be stirred during soaking and freezing.ALSO:Water-soluble gums containing glucomannans, galactomannans, glucogalactans, xylans and arabans are obtained by separating the endosperms from locust &c. seeds (see Group I).

Title: Improvements relating to electro-pneumatic braking systems for railway vehicles and the like
Inventor: STONE CYRIL JOHN
IPC: B60T13/66
Filed: 1959-05-01
Abstract: 886,559. Electro-pneumatic brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 26, 1960 [May 1, 1959], No. 14912/59. Addition to 720,449. Class 103 (1). In an electro-pneumatic brake system as claimed in the parent Specification, wherein a braking system for railway vehicles comprises two control wires and an indication wire extending throughout a train to all vehicles thereof having brakes controlled by the system, there is provided in combination with at least one of the magnet valves 11, 12 or 13, on each vehicle, a relay valve 11a, 12a or 13a, which in dependence on the supply of compressed air thereto by the associated magnet valve performs the function of the magnet valve, and the means for closing the normally open contact 31 in series with the indication wire 16 on each vehicle, is arranged to effect such closure in response to the pressure condition created at the relay valve by energization of the magnet valve. This arrangement enables the integrity of the control lines and magnets to be proved, with only one indication wire, and without the need for contacts operated by the magnet valves. As shown in the Figure, the contact 31 is closed to complete the circuit gap in line 16 by fluid pressure which is operative against the top face of differential piston 18, as the result of movement of which a slide passage 22 may provide communication between a check valve 25 connected to the brake cylinder passage, or with a passage 24 leading to chamber 20 in communication with the main reservoir passage 15.

Title: Improvements in or relating to liquid levels in burner assemblies for liquid fuels
IPC: F23K5/04
Filed: 1960-04-28
Abstract: 881,318. Regulating liquid levels. LINDE, R. VON. April 28, 1960 [April 28, 1959; April 7, 1960], No. 14974/60. Class 123(1). The oil supplied to a fuel pump 3, for delivering oil through a duct 14 to the levelling 'vessel 1 of an oil burner assembly, is controlled by a shut-off valve 19 which is located in a fuel supply duct 9 leading to the pump 3, is carried by a spring-loaded control piston 11 connected to a diaphragm 10 housed in a chamber 17, and is regulated by the air pressure from an air compressor 2 delivered through nozzle 18 and a duct 16 to the diaphragm chamber 17. The oil level in the vessel 1 is maintained constant by means of a control pump 4 having a suction duct 15 with a mouth 21 at the desired liquid level and a delivery pipe leading to the compressed air duct 16. With the burner inoperative and the compressor 2 not working the valve 19 is pressed against its seat 20 by the inner spring 12 of two springs 12, 13 which loads the diaphragm 10 and piston 11 to shut off the fuel supply to the fuel pump 3. When the burner is switched on the compressor 2 delivers compressed air through the nozzle 18 and the duct 16 to the chamber 17, the air pressure being sufficient to depress the spring 12 and open the valve 19 but insufficient to compress the outer spring 13. Should the oil level rise above the mouth 21 of the suction pipe 15 of the control pump 4 the latter delivers fuel, under pressure, to the chamber 17 to press the diaphragm 10 down further as it overcomes the spring 13 until the controlling edge 22 of the piston 11 again shuts off the delivery pipe 9 of the pump 3. As, in the course of fuel consumption, the liquid level falls below the mouth 21 the diaphragm 10, relieved of pressure from the pump 4, is moved upwardly by the spring 13 to free the delivery pipe 9. Any excessive pressure built up in the chamber 17 by the pump 4 can be relieved by the nozzle 18 or, by a spring- loaded valve, not shown. An electric motor 5 drives the compressor 2 the shaft 8 of which is connected to a shaft 6 for the pumps 3, 4 by a coupling 8 arranged in a chamber 23 which is partly filled with oil through a duct 24 communicating with the mouth 21 to lubricate and seal the shaft 6. In a modification the compressor 2 is also used to circulate oil for lubrication from the vessel 1 through a drive motor shaft bearing located above the level of oil in the vessel 1, the outlet for the fuel pump is located at a position higher up in the vessel 1, and a further valve, operated by a lever connected to the diaphragm 10 or alternatively by the oil pressure from the pump 3, gives access through a pipe leading from the vessel 11 to a burner nozzle.

Title: Improvements in or relating to gripping devices
IPC: B66C1/42
Filed: 1947-06-06
Abstract: 629,367. Lifting-dogs. JAMES, G. E. June 6, 1947, No. 15027. [Class 78 (iv)] Lifting-dogs of the kind including a pivoted linkage in the form of a parallelogram are provided with a latch member which is pivoted to a member of the linkage near one end of the vertical diagonal of the parallelogram and is engageable with another member of the linkage near the other end of the diagonal, means also being provided whereby the tongs are alternately locked open or unlocked on subsequent collapses of the linkage by means varying the angular position of the latch member. The latch member 18, Fig. 1, is pivoted at 17 to link member 14 and is provided at its upper end with a transverse pin 19 adapted to engage a pair of tracks 20 formed on the inward faces of a box 21 secured adjacent the shackle pin 12 to link member 11. The tracks are substantially heart-shaped having recesses 2, 4 in the crests of the lobes, a similar recess 1 between the lobes and an opening 22 having chamfered walls foi directing the pin into the track. The latch member is biased to turn in the direction of the arrow A by gravity or spring loading. When the under edges 13b, 14b of the tongs contact the top of a block to be gripped the linkage collapses slightly bringing pir 19 out of recess 1, where it is shown locking the linkage, until, owing to the biasing, it enters recess 2. On lifting shackle pin 12 pin 19 travels down the right hand track and out through opening 22 allowing the load to be gripped. On lowering the load, further lowering of the shackle pir causes latch member 18 to be guided by its resting on link 14, so that pin 19 re-enters the track when, owing to the inclined edge 31, it travels up the left hand track into recess 4. On raising shackle pin 12 pin 19 falls back, owing to the bias, into recess 1 locking the tongs open. In a modification a different form of latch member is used comprising a bell crank 118, Fig. 8, pivoted on shackle pin 12. The depending arm 118a is provided with a pin 33 for engaging hook 34 formed on link 14 and arm 118b is finned to link 36 whose lower end carries a pin 119 which travels in a heartshaped track 120 similar to that of the previous construction except that opening 22 is replaced by a recess 113. Recesses 111, 112, 114 thus correspond with recesses 1, 2, 4 of the previous construction. Pin 119 is biased to travel clockwise as shown by the arrows. In the locked position pin 119 is in recess 113. On collapse of the linkage pin 33 is forced down the inclined surface 35 to position 33a when pin 119 is in recess 114. On lifting shackle pin 12, pin 119 falls into recess 111 allowing pin 33 to travel back only to 33b where it is clear of hook 34 allowing gripping of the load to take place. On depositing the load, pin 33 describes exactly the same movements on surface 35 in reverse, first forcing pin 119 into recess 112 while moving between 33b and 33a positions and on again raising shackle pin 12 engaging hook 34 as pin 119 travels under gravity or supplementary spring down track 120 into recess 113.
