Title: Jet propulsion nozzle
Inventor: DENNING RALPH MURCH
IPC: F02K1/09
Filed: 1968-09-14
Abstract: 1,246,136. Jet propulsion nozzles-variable geometry. ROLLS-ROYCE Ltd. Sept. 12, 1969 [Sept. 14, 1968; Jan.30, 1969], Nos. 43825/68 and 5266/69. Heading F1J. A jet propulsion nozzle is of rectangular crosssection and of convergent - divergent form, the downstream portion comprising four rectangularly disposed walls one of which is supported for movement between a first position in which it co-operates with the remaining three walls to enclose the downstream part and a second position in which the wall is disposed adjacent the upstream part so that one side of the downstream part is open to ambient atmosphere. The nozzle shown comprises a centre-body 39 having upstream and downstream surfaces 34, 41 which divides the nozzle into two convergent - divergent nozzles 31, 40 each in accordance with the invention. The assembly comprises two parallel side walls 35 between which the centre-body 39 extends and upper and lower walls 33 which together with the surfaces 34 of the centre-body define the convergent portions 31. The walls 33 terminate just downstream of the throat 36. Vanes 37 extend between the walls 33 and the centre-body. The divergent portions 40 are defined by upper and lower walls 42 and the surfaces 41 of the centre-body, the walls being mounted for movement between an operative portion A and a retracted portion B see Fig. 2, each divergent portion being open to ambient atmosphere when the wall 42 is in the retracted position. Each wall 42 is of outwardly curved form and is mounted at its two sides in a re-circulating roller bearing 45, see Fig. 5. A bracket member 50 is secured at each edge of the wall 42 and the rollers cooperate with the bracket and with a track member 46 secured to the side wall 38. A cable 60 passing round pulleys 61, 62 is secured to each side of each wall 42 by means of a fitting 63 and the forward pulleys 61 at each side are interconnected by cable 67. A shaft 64 inter-connecting the upper pulleys 61 is drivable by means of an air motor 66 Fig. 3 (not shown) whereby the walls 42 may be moved axially between the operative and retracted portions. Fairing members 80 are provided over the convergent nozzle portions each fairing having extensions 85 which terminate at points 86. When the walls 42 are in the retracted positions ambient air may flow into the wedgeshape spaces 87 which are formed when the pressure in the divergent portions 40 is not significantly above ambient, the outer surface of jet stream being indicated at J 2 .

Filed: 1928-02-21
Abstract: 312,129. India Rubber, Gutta Percha, &. Telegraph Works Co., Ltd., and Avery, W. L. Feb. 21, 1928. Springs, arrangement of.-Relates to mountings for the wheels of vehicles and particularly aircraft, of the kind in which resilient suspension members are carried within the wheel mounting. The resilient members are extended or compressed in a direction parallel to the wheel axis by levers pivoted to the mounting from which they extend laterally for connection to the body of the vehicle, the levers being movable in planes at right or other angles to the plane of rotation of the wheel. In the form shown in Fig. 1, the mounting comprises circular flanged plate 3, 4, carrying a cylindrical shell 15 and eccentrically fixed to a tube 1 secured to the axle 2 by a split clip 6 integral with the plate 4. The end of the tube 1 is split so that the clip 6 secures the plate 4 to the tube and the tube to the axle. The wheel 12 rotates on bearings 10, 11. The springs 18 are mounted between the fixed plate 3 and the flange 17 of a collar 16 sliding on the tube 1, the springs being located by pins 19, 20. A pair of L-shaped levers 24, arranged one on each side of the tube 1, are each pivoted at one end on a pin 28 carried by lugs on the plate 3 while their other ends project through vertical slots in the plate 4, and are connected by a strut to the body of the vehicle. The levers are connected at 32 to links 34 which are pivoted to the collar 16, the links being normally horizontal. Longitudinally arranged radius rods are provided to constrain the movement of the axle relatively to the body. In the modification shown in Fig. 4, the plates 53, 54, tube 51 and shell 65 are substantially the same as the corresponding parts in Fig. 1 except that the plates are concentric with the tube 52. The resilient elements comprise indiarubber rings 68 and metal separating plates 69, arranged between the fixed plate 53 and the flange 67 of the collar 66 sliding in the tube 51, the rings 68 and plates 69 being formed with inter-engaging annular ribs and grooves 70, 71. The levers 74 extend through vertical slots in the plate 54, are pivoted at 77 to the collar 66, and are connected at 84 to links 82 pivoted at 80 to brackets 79 extending inwardly from the plate 54. Recoil buffer-rings 85 are arranged between the flange 67 and a fixed flange 87. Two of the above described mountings may be used in conjunction with a single wheel, the levers extending on opposite sides of the wheel. In this case, an axle need not be provided, but a short axle may be used with the radius rods connected to its ends.

IPC: C23C2/10
Filed: 1915-08-10
Abstract: 101,128. Mark, C. Aug. 10, 1915. Coating by dipping.-In coating iron or steel articles with an alloy containing zinc, for example one of the lead, zinc, and tin or antimony allovs described in Specification 11557/15, a small quantity of zinc is added at intervals to the molten bath to maintain the desired proportion (preferably not more than 5 per cent.) of zinc in the alloy. The additional zinc is preferably added in a molten state, this permitting of the use of a bath at a temperature below the melting-point of zinc. The temperature is preferably between 650 and 850‹ F., but may be increased beyond the highest limit, particularly when antimony is used in the alloy. By adding the zinc in slight excess, some of it collects on the surface and affords an indication as to the proportion of zinc in the alloy.

Abstract: 559,682. Unsaturated ketones. SHELL DEVELOPMENT CO. April 28, 1942, No. 5714. Convention date, June 23, 1941. [Class 2 (iii)] Unsaturated ketones are produced by contacting the vapour of a lower ketone with an alkali or alkaline earth metal salt of a weak amphoteric inorganic acid at above 250‹C. Suitable catalysts are sodium, calcium, barium, magnesium and beryllium aluminates, sodium, calcium and caesium borates, potassium and calcium zincates, magnesium and lithium plumbates, potassium and strontium stannates, sodium and magnesium antimonates, calcium aurate, sodium, rubidium and calcium arsenates, and potassium titanate. The preparation of catalysts consisting of calcium aluminate, calcium metaborate and of sodium aluminate on pumice respectively is described. Tabular particulars are given for the production of mesityl oxide and isophorone from acetone under various conditions. To obtain mainly isophorone, the mesityl oxide produced may be recycled, thus reducing the further production of this substance. Instead of acetone other ketones may be employed, especially methyl ketones, but including also cyclopentanone, cyclohexanone, and acetophenone. Specification 552,706 is referred to.

Abstract: 511,301. Refrigerating. ELECTROLUX, Ltd. Feb. 24, 1938, No. 5880. Convention date, Feb. 24, 1937. [Class 29] Absorption systems.-A continuous-cycle inert gas system having low and high temperature evaporators 16, 18, Fig. 1, and the usual heat exchanger 14 for the weak gas mixture passing from the absorber 11 to the low temperature evaporator and the strong gas mixture flowing to the absorber is provided with a second exchanger 15, where the weak gas before entry into the low temperature evaporator is cooled by the gas mixture flowing from the low temperature evaporator to the high temperature evaporator. In the embodiment for a cabinet the evaporators are supplied from main and auxiliary condensers 27, 40, Fig. 3, the first receiving vapour from the generator through a conduit 25 and rectifier 26. The condensers become effective in turn at successively higher cooling-air temperatures, and the condensate collected in a U-seal 28 flows through a conduit 30 to a precooler 31 the vapour space of which is connected to the heat exchanger 14. A further condenser 42 for abnormal conditions is connected to the top of the seal and condensate therefrom drains at 39 to the rich gas space of exchanger 14. The precooler 31 is preferably arranged within the insulation of the usual removable wall element 51, Fig. 4, of the cabinet carrying the evaporators. The low temperature cooler is formed with ice-making recesses and is insulated except at the front by a layer of sponge rubber 57 having ribs 48, Fig. 6. It is located close to the cabinet top and occupies the whole width so as to have little influence on the storage air circulation.
