Title: Novel unsaturated aldehydes
IPC: C07C47/19
Filed: 1963-08-21
Abstract: The invention comprises unsaturated aldehydes of general formula <FORM:1031076/C2/1> in which R is a hydrogen atom or an acyl group derived from a carboxylic acid, R may be, for example, formyl, acetyl, propionyl, butyryl, valeroyl, phenacetyl, benzoyl, nitrobenzoyl or anisoyl. The compound in which R represents hydrogen may be prepared as follows: 3,7 - dimethyl - octyn - (1) - diol - (3,7) is partially hydrogenated in the presence of a catalyst to produce 3,7-dimethyl-octen-(1)-diol-(3,7) which is then oxidized, for example by chromic acid in one stage or in two stages by first converting the diol into a 1-halo-3,7-dimethyl-7-hydroxy-octene-(2) and then oxidizing this by nitronic acid oxidation.  The compounds in which R represents an acyl group may be prepared by converting a carboxylic acid diester of formula <FORM:1031076/C2/2> in which R1 and R2 each represent an acyl group to the corresponding allemic diester [3,7 - dimethyl - 1,7 - diacyloxy - octadiene-(1,2)] in the presence of a re-arrangement catalyst, e.g. silver carbonate, silver acetate, silver trifluoroacetate, silver nitrate, silver fluoroborate, silver perchlorate, copper powder or copper acetate, followed by partial saponification of the re-arrangement product.

When the pump outlet 4 has reached the vicinity of the coupling unit 5 of the stationary discharge pipe, a projection 16 on the outlet comes into contact with a support 9. Thereafter, as it is lowered still further, the pump pivots about this contact until each member 11 comes against an inclined plane 13 of a stop 12. The point of contact 14 between the member 11 and the inclined plane 13 is at a distance a below the line of action of the force R exerted on the pump casing by the pump pressure, whereby the resultant clockwise torque on the pump casing presses the member 11 further downwards against the inclined plane to intensify the force pressing the self-aligning surfaces 7, 8 of the coupling unit 5 and outlet 4 into sealing engagement. In a modification the surfaces 7, 8 are transposed.

Title: Improvements in Helicopter Engine Air Inlets
IPC: F02C7/052
Filed: 1968-08-30
Abstract: 1,192,503. Cyclone separators. GENERAL ELECTRIC CO. 30 Aug., 1968 [29 Sept., 1967], No. 41489/68. Heading B2P. [Also in Division F1] The invention relates to air intake structure for a gas turbine engine which constitutes the power plant of a helicopter. A cowl defining an air intake is provided axially aligned with and forward of the engine intake, the cowl having a plurality of filters extending radially therethrough, the filters serving to remove dust and like particles and passing essentially clean air to the interior of the cowl when there is air flow therethrough. Closure doors are provided which are movable between a first position in which air may flow axially through the cowl to the engine intake, and a second position in which such air flow is prevented. A valve is associated with each filter element, the valve closing when air flows axially through the cowl when the closure doors are open, thus preventing flow of air through the filter elements, and opening when such axial air flow is prevented by closing of said doors. The helicopter shown is provided with two gas turbine engines E, each having a cowl 14 axially aligned with the engine intake. The cowl 14 comprises an outer screen 22, an outer panel 24 and an inner panel 26. A plurality of vortex type filters 28 are associated with the panels 24, 26 each filter comprising a vortex tube 30 and a frusto conical outlet 32. A flap valve 36 is pivotally mounted at 37 adjacent the outlet 32, being shown in the open position in Fig. 6 and in the closed position in Fig. 7. A pair of closure doors 34 is mounted at the forward open end of the cowl. In normal operation the doors 34 are open and air flows axially through the cowl thus acting to close the flap valves 36 so that no air enters through the filters 28. When operating in dust-laden conditions the doors 34 are closed so that no air flows axially into the cowl and the flap valves 36 now open, and air flows 'radially inwardly through the filters 28, dust particles being separated out and clean air passing into the engine intake 16. The dust particles separated out pass between the panels 24, 26 and are discharged through outlet 35, Fig. 2 not shown.

Abstract: 1,047,743. Air cushion vehicles. SOC. BERTIN & CIE. Oct. 22, 1963 [Oct. 27, 1962], No. 41636/63. Heading B7K. In a ground-effect platform supported by a plurality of air cushions, an air supply apparatus comprises at least one air pump having an outlet duct for the air under pressure, a pipe connected to said outlet duct and provided with multiple branches which each connect with an air cushion and a pivoted flap valve in each branch provided with means for preventing complete closure of the valve when the pressure in the corresponding air cushion becomes momentarily close to the ambient air pressure. A fan 7 (Fig. 1, not shown) driven by engine 6 delivers air to a pipe or duct 5 from which branches 3a, 3b extend into downwardly-extending supports 13a, 13b for flexible skirts 2a, 2b. The opening into each branch carries a pivoted flap valve 8a, 8b respectively which is urged by a spring 9a, 9b into the open position against a stop 11a, 11b. A stop 10a, 10b prevents the valve from closing completely. In operation, if the vehicle passes over a depression so that the pressure in a cushion such as 1b drops suddenly the valve 8b will be closed against the action of spring 9b thereby preventing excessive loss of air from duct 5. When the pressure in the cushion returns to normal the valve will automatically open. In a further embodiment each valve may be pivoted intermediate its ends and biased by two springs against the action of a servo-jack which opens and closes the valve in response to ambient conditions.
