A gas-cushion vehicle for operation over water is provided with a spaced pair of walls depending from the bottom sides of the vehicle body to form at least part of the lateral boundary of the vehicle-supporting cushion, and means for closing at least one of the gaps between the ends of the side walls, said means comprising a structural member movable relative to the vehicle body to close an upper part of said gap and means for causing a curtain of moving fluid to issue from the lower portion of said structural member to close the remainder of said gap. The vehicle which comprises side walls (not shown), may comprise at each end a transverse duct 31 capable of vertical movement between slides 32, 33 under the control of a jack 34. The duct comprises an air inlet 37 from a supply pipe 35 and a nozzle 30 from which the curtain jet 18 issues. In the embodiment of Fig. 15 the variation in height of the curtain forming orifice is achieved by a sliding plate 56 which is moved from a retracted position by a jack 57. Other embodiments employ a duct mounted on the body of the vehicle by a scissors linkage and sealed to the body on its inner or cushion-forming side by a flexible diaphragm, or a series of hinged flaps, operated by a jack and linkwork so that they may be moved from an inoperative position against the underside of the vehicle body to positions in which they form downward extensions of the walls of the curtain-forming jet orifice. The apparatus may be applied to curtain systems providing re-circulation and an embodiment comprising vertically movable cushion-compartmenting jet orifices is decribed, in which fans in the end walls supply the peripheral curtain ducts and vertically mounted fans supply the compartmenting ducts. The area of the curtain-forming duct nozzles may be varied and movable curtain-forming ducts may be mounted in the side walls. In the latter arrangement the curtain flow may be increased to raise the sidewalls clear of the water to enable the vehicle to traverse land. A further embodiment discloses inflatable walls for the curtain-forming jets whereby the degree of inflation is used to adjust the height of the nozzle outlet.

Title: Lysergic acid-alkaloids
IPC: C12P17/18
Filed: 1960-08-29
Abstract: The invention comprises two isomeric derivatives of D-lysergic acid and D-isolysergic acid having a carbinolamidic structure and empirical formula C18H21O2N3, which form maleates C22H25O6N3, yield acetaldehyde and D-lysergic acid amide or D-isolysergic acid amide on hydrolysis and are probably of the formula <FORM:0883330/IV (b)/1> also a process for their preparation by filtering a culture broth produced by the fermentation in submerged culture of virulented strains of Claviceps paspali Stevens and Hall, and extracting the filtrate with an organic solvent at a pH between 7 and 9 and at a temperature between 0 DEG C. and 10 DEG C.  The extract is then concentrated and purified by successive transfers from the organic solvent (e.g. chloroform) and an acidic aqueous phase (e.g. tartaric acid solution) between 0 DEG C. and 10 DEG C., adjusting the pH of the aqueous phase to pH 7-9 before each extraction with the organic solvent.  Treatment of either of the new compounds with acid (or with alkali) yields an equilibrium mixture of the two. Examples detail (a) the preparation of D-lysergic acid amide, D-isolysergic acid amide and small amounts of the new compounds (using normal temperature extraction) and (b) isolation of the new compounds by extraction at 0.5 DEG C. and equilibration of the individual isomers with aqueous acetic acid.

Abstract: 572,724. Propelling aircraft. HALFORD, F. B., and MOULT, E. S. Nov. 10, 1939, No. 29816. [Class 4] A blower G driven by an internal-combustion engine working on the two-stroke cycle delivers scavenging air to the manifold G<1>. The mixed exhaust gases and scavenging air are discharged through rearwardly-extending nozzles E<1> so as to produce a reactive effect assisting in the propulsion of the aircraft. The size of the nozzles may be adjusted so as to vary the back pressure on the engine as desired. The ejector thrust may be assisted by a liquid fuel burner in the nozzle or some of the blower air may be byepassed directly to the exhaust manifold. The invention involving the.use of a two-stroke cycle engine is contrasted with that described in Specification 471,177 where the exhaust gases from an ordinary aircraft engine are discharged rearwardly to increase the propulsive effect.

Title: Liquid fuel injection pumps
Inventor: KEMP KENNETH ALBERT WALTERS
IPC: F02M41/14
Filed: 1960-08-30
Abstract: 925,979. Fuel injection pumps. C. A. V. Ltd. Aug. 17, 1961 [Aug. 30, 1960], No; 29830/60. Class 102(1). [Also in Group XXIX] A fuel injection pump of the kind comprising a rotary disc distributer, driven from the engine, having a head 15 formed with a bore 17 which houses pump pistons 18, the pistons being moved outwards by the delivery of a feed pump and inwards by lobes on a cam 20 to deliver fuel in turn to the engine cylinders, characterised in that means are provided to rotate the cam in response to engine speed to vary the timing of injection. The pump housing is formed with a cylindrical chamber 29, parallel to the tangent to the cam, which houses a movable piston member 32. A cylindrical valve member 36 is housed in a bore of the piston 32 and extends into an extension chamber 31 in the manner of a piston or plunger to seal this chamber from the chamber 29. An axial bore 45 in the valve member 36 leads to a groove 48 and includes a non-return valve 46. The piston 32 and valve member 36 are loaded by separate springs 34, 37 and the piston receives an arm 33 secured to the cam. In operation, fuel pressure from the feed pump is fed through passage 42 to chamber 31 and acts on the end of the valve member 36. When this pressure overcomes the spring 37 the valve moves to connect groove 48 with a passage 49 in the piston and fuel is fed to a chamber surrounding the valve to act on the left-hand side of piston 32. The piston 32 moves until the passage 49 is closed to the groove 48 and thus rotates the cam. If the pressure in chamber 31 drops, the valve member 36 is moved to the left by the spring 37 and the passage 49 is opened to drain causing corresponding movement of the piston 32 to the left. In a modification, the valve 36 is replaced by a piston valve without the axial passage, a branch from the passage 42 or separate fluid supply being provided which, under the control of movements of the piston valve, is admitted to or exhausted from the left-hand face of the piston, the supply passage includes the non-return valve. As shown, the piston valve extends into the chamber 31 through a sleeve member 36 which is capable of slight transverse movement to allow for misalignment. When a piston valve is used, this may be formed in two parts.

Abstract: 741,643. Hose couplings. COMPOFLEX CO., Ltd., and USHER, R. A. Oct. 18, 1954 [Oct. 29,1953], No. 29919/53. Class 99(1). In a coupling for a hose 10 comprising a body 15 of rubberised fabric or other flexible material, with or without an embedded wire helix, and having helical corrugations at least on the internal surface thereof, an insert 20 provided with an external screw-thread 21 having a pitch corresponding to that of the corrugations is screwed into the hose and a sleeve 18 holds that portion of the hose engaged in the screwthread of the insert in compression, a sealing ring 19 preventing leakage of fluid from the hose and along the insert. As shown in Fig. 1, the insert 20 and sleeve 18 each have doublestart screw-threads 21, 22 appropriate to the pitch of the internal and external wire helices 17, 16, the root diameters of the screw-threads being equal to the internal and external diameter of the helices. The first few turns of the helix 16 are removed to bare the end portion 23 of the hose body 15 and the sleeve 18 is screwed onto the helix, a tapered, rigid sealing ring 19, which may be integral with the insert 20, being accommodated in a recess 24 in the sleeve and disposed over the portion 23. The insert 20 is screwed into the helix 17 and the coupling is completed by turning the sleeve and insert in opposite directions thereby squeezing the portion 23 between the ring 19 and the exterior of the insert. Where the hose lacks resiliency a U-shaped strip of rubber is inserted over the portion 23 to assist in making a fluid seal. If the helix 16 is removed after manufacture of the hose thus leaving a groove between alternate turns of the helical corrugations in the hose body, the sleeve 18 is formed with a single start thread, the crests of that thread accommodating the space left by removal of the helix ; similarly, the insert has a single-start thread when the helix 17 is removed. The sleeve is provided with inner circumferential serrations or ribs when the hose has a smooth external surface. In modifications, (a), the insert 20, Fig. 2, has a groove 27 into which is fitted a rubber sealing ring 26 of circular cross-section, and a similar ring 28 is disposed over the portion 23 of the hose body, a nut 29 being screwed onto the end of the sleeve 18 to compress the ring 28 between the end of the sleeve and a rigid ring 19, (b), the form shown in Fig. 1 incorporates a rubber sealing ring 26 as shown in Fig. 2, and (c) the hose is compressed onto the insert by swaging the sleeve 18, or by a band clip.
