Filed: 1948-08-16
Abstract: 643,241. Jet propulsion engines. WEST INGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 16, 1948, No. 21594. Convention date. Sept. 17, 1947. [Class 110(iii)] In a jet propulsion engine having a turbine with speed control means and a variable area propulsion nozzle adjustable by means of a movable component, this component and the speed control means are controlled by a common control member so that during initial movement of the member, with the nozzle area at a predetermined value, the speed of the turbine is gradually increased to a maximum and during further movement of the member the nozzle area is reduced to increase the thrust. The speed of the gas turbine plant shown is regulated by a governor 24 which controls the fuel supply to the combustion chamber or chambers 14. The area of the propulsion nozzle is regulated by a movable tail cone 20 actuated by a reversible electric motor 30 controlled by a controller 31 so that there is one position of the tail cone 20 for each position of the lever 32. The governor 24 and lever 32 are actuated by the followers 34,. 35 of the cams 36, 37 which are so arranged that until the throttle lever 38 is brought to the full speed position the tail cone 20 remains stationary in a position in which the nozzle area A is larger than that required for full thrust at full speed and further movement of the lever 38 past that position reduces the area of the propulsion nozzle and so increases the thrust.

Abstract: 784,013. Generating combustion products under pressure. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 27, 1955 [July 28, 1954], No. 21730/55. Class 51 (1). [Also in Group XXVI] A jet propulsion engine comprising one or a number of pulse jet engines arranged within a ram jet nacelle having at its inlet a diffuser and at its outlet a discharge nozzle in which the exhaust pipes of the jet engines are arranged to discharge each into an ejector tube arranged to suck air which has passed over the pulse jet unit or units has supplementary fuel injected into the gas flow from the combustion chambers of the pulse jet units upstream of the outlet orifices of the ejectors. A ram jet nacelle 1 having an inlet diffuser 5 and a discharge nozzle 3 surrounds a number of pulse jet units p1, p2. The inlets of the pulse jet units which are formed by aerodynamic valves 4 are located at the downstream end of the diffuser 5. The exhaust pipes 7 of the pulse jet units discharge into the ejectors 8 which are arranged to suck air which has passed over the pulse jet units. Supple- .mentary fuel is injected at 10 into the exhaust .pipes 7. This fuel is ignited automatically as soon as the supply valve 11 is opened by the hot gas discharged from the pulse jets. The fuel injectors may be arranged in the front portion of the ejectors. The wake created by the ejectors stabilizes the flame, but stabilizing screens may be provided, if required. The fuel injectors may be arranged between the outlet of the exhaust pipes 7 and the inlet to the ejectors 8, or inside the divergent portion of the ejectors. Due to the turbulence in the ejectors 8 the fuel may be injected at low pressure and without vaporization and the fuel injectors may be arranged to face other than in the transverse direction. The outlets 12 of the ejectors are preferably arranged at a distance upstream of the discharge nozzle 3 which is great enough to allow of completion of the combustion before the nozzle and before the commencement of che convergent portion 13. The ram jet nacelle 1 is partitioned between the planes containing the inlet and outlet orifices of the ejectors. The partition has a fixed part 15 on which are pivoted movable shutters 16. The movable shutters 16 are operated by manual control or automatically as a function of the dynamic pressure of flight so that at low aircraft speeds all of the air passing through the cowling passes through the ejectors and at high speeds is by-passed round the ejectors direct to the discharge nozzle 3. The pulse jet engines are mounted in the nacelle by radial arms 19 attached to the aerodynamic inlet valves 4 and by radial arms 21 provided with collars 20 that support the exhaust pipes. Specifications 715,323, [Group XXVI], 743,492 and 743,498, [Group XXVI], are referred to.

Abstract: 573,257. Indicating liquid levels. SIMMONDS DEVELOPMENT CORPORATION, Ltd. Dec. 29, 1943, No. 21790. Convention date, March 9. [Class 123 (i)] A liquid level or contents indicator is actuated by hydrostatic pressure down to a predetermined level, and below that level by floatoperated means. A bellows 18 is supported on an annular partition 17 in a casing 14 mounted on the bottom of a tank. The bellows contains a helical spring 22 and its interior is open\to the air at 28. A float 40 on an arm 38 pivoted at 34 acts on a rod 30 carried by the bellows. A pivoted arm 52 actuated by a link 48 moves over a resistance 56 to operate an indicator in known manner. When the liquid level rises, the indicator is operated by the float until its arm reaches the stop 44, and thereafter by the hydrostatic pressure on the bellows. In a modification, the resistance is carried by a pivoted plate which is actuated by the float, the arm 52 being actuated by the bellows as before. The float may cause larger movements of the indicator than the bellows, for the same change of head. Specifications 471,224 and 482,802 are referred to.

Title: Improvements in and relating to the solidification of hot liquid resinous material
Inventor: CRESPIN GEORGE THEODORE FLOR
IPC: B01J2/24
Filed: 1959-06-25
Abstract: 860,174. Solidifying hot liquid resins. SHELL RESEARCH Ltd. June 25, 1959, No. 21837/59. Class 87(2). Hot liquid resinous material is fed through the nip of two co-operating rolls 7, 9 rotating toward each other (as viewed from above), the roll 9 being internally cooled and having at its periphery a series of annular grooves and ridges, the solidified resinous material removed from the groove roll 9 as a continouus longitudinally-moulded sheet 14 comprising longitudinal strip portions held together by thin webs, transverse imprints (e.g. incisions or indentations) formed in the moulded sheet, and the sheet finally subjected to mechanical treatment to cause breakage along the webs and imprints. In the apparatus illustrated the resinous material is supported in contact with the grooved roll 9, for a length of travel of the roll which is only a minor portion of its circumference, by an endless belt 6 which passes with the resinous material through the nip of the rolls. The belt 6 then conveys the material between an imprinting roll 17 provided with longitudinal ribs 18 and a plain roll 19. The moulded sheet is subjected to further cooling provided by the nozzles 20 which spray coolant liquid against the underside of the belt and, if desired, this can be supplemented by blowing air from the dust-like cover 21 over the upper surface of the sheet. The longitudinal webs of the sheet being thinner than the transverse imprints, the cooled sheet is first broken longitudinally by its passage between rubbercovered breaker rollers 15, 16 and then transversely by striking against a deflector plate 24. The imprinting roll 17 may be adjusted vertically with respect to the belt 6 by means of an adjustable stop 31 attached to the machine structure and a piston and cylinder mechanism 32 arranged to exert a downward force on the roll and thus hold it in the position determined by the setting of the stop. The invention is of special application for resins, particularly epoxy resins with melting points between 65‹ and 155‹C., which are brittle when solid and which do not fracture cleanly on being subjected to the action of a rotating cutter but shatter into powder and small fragments. Specification 860,173 is referred to.
