Abstract: 608,459. Helicopters. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Feb. 25, 1946, No. 5755. Convention date, Feb. 26, 1942. [Class 4] The hub of a helicopter rotor is connected to the fuselage by a ball joint and a flexible connection permitting tilting of the rotor, the flexible connection transmitting the sustaining forces while the ball joint transmits only the lateral forces. In the construction shown in Fig. 1, the hub 4 rotates on a sleeve 5 mounted by a ball joint 7, 8 on a member 8a integral with the aircraft structure. The flexible tie member 10 is secured at its upper end to a ring 11 and at its lower end to the member 8a. Tilting of the rotor is effected by control rods 6.

Abstract: 608,461. Liquid-fuel supply. LUCAS, Ltd., J., and IFIELD, R. J. Feb. 25, 1946, No. 5766. [Class 75(i)] [Also in Group XXVI] Liquid-fuel controlling means for a prime mover comprises a manually operable valve d for controlling the flow of fuel to a-main burner, a bye-pass valve m for controlling the flow of fuel to a pilot burner and also an idling supply to the main burner, and pressure responsive means k for controlling the bye-pass valve m. The valve d may be operable through a rack and pinion g, Fig. 1, and when the valve is open fuel may be supplied to the main burner from a passage b and through a passage c, some fuel also passing through a passage p to a chamber j and passage q to the pilot burner. The bye-pass valve m may be supported -by a capsule k or by a spring loaded piston or diaphragm so that if the pressure exceeds a predetermined amount, the capsule k moves to close the valve m and shut off the fuel supply to the pilot burner. If only sufficient fuel to maintain combustion at the main burner is required, the pilot burner may be cut off by a valve and the valve d closed, so that fuel is supplied through the passage p to the chamber j and passes to the main burner through a passage r controlled by a non-return valve s. A relief passage t controlled by a non- return valve u may be provided in communication with the chamber j. In the modification of Fig. 2, fuel is supplied to the inlet b through piping w, some being bye-passed to the passage p and the valve m which may be controlled by a bar 2 pivoted at one end and attached at the other end to a pressure responsive capsule k, the method of operation of this form being exactly similar to that of Fig. 1.

A transport apparatus has a frame with a front closure member 16, a rear member 14 and side members 10, 12 defining, with a blanket 18 connected between at least the sides 10, 12 of the frame, a space which is supplied with pressurized air to form an air cushion so that the blanket 18 flexes to provide bottom and at least partial side support for cargo carried by the apparatus while the air cushion supports the cargo. To increase stability strut side support members 24 are attached to the opposite sides of the side members 10, 12 from the blanket attachment. In use, to transport a ship, the front gates 32, 34 are opened and the transporter apparatus is run down a ramp so that the blanket is positioned under the hull. The front gates are closed and the excess water above the blanket pumped out. Air pressure is then built up under the blanket until there is sufficient cushion pressure to lift and support the ship. The framework is provided with wheels 26 to enable the transporter to be moved on rails or on a relatively smooth surface either by engines contained in the frame or by pulling or pushing by, for example, diesel engines. The area under the blanket may be subdivided into compartments at slightly different pressures.

Abstract: 1534179 Preparing cyclohexenylethyl silicon compounds CHEMIEWERK NUNCHRITZ VEB 17 Feb 1976 [24 Feb 1975] 06136/76 Headings C3S and C3T Organo-silicon compounds containing 2 - (cyclohex - 4 - enyl) - ethyl groups are prepared from silicon compounds containing SiH groups, e.g. silanes and siloxanes by a process wherein an SiH group containing silicon compound is reacted in the presence of hexachloroplatinic acid as addition catalyst at atmospheric pressure and at a temperature of from 20‹ to 200‹ C. with vinyl cyclohex-4-ene to give a 2-(cyclohex-4-enyl)-ethyl silicon compound. The amount of catalyst used is from 0À0001 to 5 ml. of 0À1 M hexachloroplatinic acid dissolved in an organic solvent, e.g. isopropanol, per mol. of vinyl cyclohex-4-ene. Suitable starting materials may have the general formula HSi(R) 3  wherein the radicals R are the same or different and are halogen atoms or alkyl, cycloalkyl, cycloalkenyl, aryl, alkoxy, carboxy or aroxy radicals. Other starting materials are siloxanes containing SiH groups, e.g. methyl silicone oils. The process may be carried out continuously. In an example a mixture of 5 mol. of vinylcyclohex-4-ene, 5 mol. trichlorosilane and 0À25 ml. of 0À1 M hexachloroplatinic acid in isopropanol is passed, over the course of one hour, through a 2 metre packed column the upper third of which is initially at ambient temperature; the middle third at 75‹ C.; and the lower third at 50‹ C. During the addition reaction the temperature in the column rises to 120‹ C. and at the end of the reaction a 96À5% yield of 2-(cyclohex-4-enyl)-ethyl trichlorosilane is obtained. The 2 - (cyclohex- 4 - enyl) - ethyl silicon compounds obtained by this process when incorporated in silicon lacquers impart air drying properties to the lacquers.
