Title: A new or improved control valve for fluid pressure systems
IPC: B64C25/44
Filed: 1941-02-22
Abstract: 546,293. Vatves. BENDIX, Ltd., and IRVING, J. S. Feb. 22, 1941, No. 2431. [Class 135] [Also in Group XXXIV] A valve device for controlling the supply and exhaust of fluid pressure to and from a fluid pressure system as 'for example the fluid pressure braking system of an aircraft comprises a pair of valves farmed by planished steel discs co-operating with a pair of seatings one of which is stationary and controls the admission of fluid to the power cylinder and the other is movable by manually-actuated means and controls the exhaust of fluid from the power cylinder. As shown in the Figure, the main casing 10 is formed with a cylindrical bore 11 having a lateral bore 26 leading to the apparatus controlled, a lateral exhaust port 32 and closed at one end by a pressure inlet fitting 12. This fitting houses the supply valve disc 14 which is pressed by inlet pressure and a spring 17 towards a removable seat 15 held against a shoulder 18 on the fitting 12 by a ported sleeve 19. The exhaust valve disc is housed in the sleeve 19 between an abutment 20 thereon and a tappet pin of slightly less length than the distance between the discs when engaging the seat 15 and abutment 20 respectively. The exhaust valve seat is formed on the end of a tubular member having ports 33 to establish communication with the exhaust port 32 and provided with a collar 30 soldered to a metallic bellows 38 soldered at the other end to a fitting 36 secured in the end of the bore 11. A manually adjustable member 34 slidably mounted in the fitting 36 is adapted to vary the compression of a loading spring 35 bearing on the collar 30. In the position shown, the passage 26 is connected to exhaust via ports 31, 33, 32. When the plunger 34 is moved to compress the spring 35, the sleeve 27 first engages the disc 21 to interrupt the exhaust connection and then acts through the tappet 22 to lift the supply valve from its seat. As pressure builds up in the passage 26, the pressure acting on the bellows 38 moves the valve assembly to the position in which both valves are closed.

Title: New or improved twist lace fabrics and the method of producing the same
IPC: D04C1/00
Filed: 1926-01-28
Abstract: 261,946. Price, W. H. Jan. 28, 1926. Lace.-Fabrics somewhat resembling knitted fabrics in elasticity and other qualities are produced on twist lace machines in cycles of one or two motions. The fabrics may be made on plain net machines without traversing the carriages. Fig. 2 shows a net composed of equal numbers of warp and bobbin threads wherein both warps such as w<3>, w<4>, and bobbin threads, such as b<3>, b<4> cross and recross in pairs. One bobbin thread of each pair may, however, be suppressed and the warps may be grouped in threes or fours to form plaited pillars connected together by single bobbin threads. The runs of thread such as c<2> give the fabrics a ribbed appearance.

Title: Improvements in or relating to regulating means for gas turbine installations
IPC: F02K1/16
Filed: 1943-02-19
Abstract: 587,516. Gas turbines; jet propulsion of aircraft; speed governors. BRISTOL AEROPLANE CO., Ltd., and FORTESCUE, P. Feb. 19, 1943, No. 2824. [Classes 57 and 110 (iii)] [Also in Group XXIX] The gas turbine plant of an aircraft drives one, or, a pair of air-screws and provides a propulsive jet. The turbine comprises two rotors, one of which drives the air compressor and the other the air-screws, and the power taken by the air-screws is governed, by varying the pitch of the blades, to maintain a constant ratio between the speeds of the two rotors. To this end, the turbine rotors drive opposite members of a bevel gear differential and the cage, carrying the planet wheels which rotates when the driven wheels do not rotate equally in opposite directions, is geared to an oil pump 88, Fig. 3. This pump transfers oil from one end to the other of a cylinder containing a valve 83 and consequent movement of this valve admits oil from a pump 77 to one side or other of a piston 74 and empowers the latter to vary the pitch of the air-screw blade 73. Specification 587,558 is referred to.

Title: Electromagnetic coupling
IPC: F16D13/75

Abstract: 905,229. Friction clutches. EATON MANUFACTURING CO. Jan. 27, 1959 [Jan. 31, 1958], No. 2882/59. Class 80 (2). [Also in Group XXXII] An electromagnetic clutch having a rotatable pole structure 13 carrying an energizing coil 35 and an axially movable armature 10 carried by axial guide means 53, has spring means 65 with gripping portions gripping the guide means and resilient portions providing axial release loading for the clutch. The springs 65 have flat portions 66 through which the guide-pins 53 extend and two hook-shaped resilient arms 68, 69 extending outwardly and engaging keepers 75 formed in the armature support 48. The inner edges of the body 66 are deflected axially to provide guide gripping portions 71 and further axially extending portions 72 are provided to limit the axial movement of the arms 68, 69. When the clutch coil is energized to attract the armature 10 against the friction surface 59 the spring portions 68, 69 are moved axially to provide resilient clutch release on de-energization. Should the predetermined air gap be excessive the inturned gripping portions 71 of the springs will move along the guides 53 when the arms 68, 69 meet the projections 72, and will grip the guides at a new position to provide the correct gap on release of the armature. To assist cooling the armature faces may be radially grooved. In another embodiment, Fig. 6, the guide pins 83 are screwed into the armature ring 80 and slide in bushes 86 in the driven member 87. Counterbores 98 locate substantially circular springs 93 having inwardly-extending radial gripping portions 96 and helical axially-extending arm portions 95 providing for clutch release by bearing against the end surface of the counterbores. Specification 905,230 is referred to.

Title: Separation of mixtures of esters and alcohols
IPC: C07C67/48
Filed: 1958-01-29
Abstract: A mixture of an ester of a monohydric alcohol and the corresponding non-esterified monohydric alcohol is separated by extractive distillation by treating the vapour of the alcohol-ester mixture with a polyhydric alcohol in counter-current, distilling off the pure ester overhead, and leaving the polhhydric and monohydric alcohols in the lower part of the distilling column.  The process is especially suitable for the separation of lower aliphatic acrylic acid esters, such as methyl, ethyl, or butyl esters from the corresponding alcohols using ethylene glycol or glycerine as the polyhydric alcohol.  In examples, methyl acrylate, methyl propionate and ethyl acrylate are separated from their corresponding alcohols with the use of ethylene glycol in each case.  The resultant mixture of monohydric alcohol and ethylene glycol may be separated by direct distillation. From 200 to 1000 parts of polyhydric alcohol are used for each 100 parts of monohydric alcohol.
