Title: Improvements connected with pressure vessels
IPC: B21C37/28
Filed: 1934-04-12
Abstract: 426,155. Expanding tubes into seatings. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.-(Assignees of McAllister, A. R. ; 240, Storer Avenue, Akron, Ohio, U.S.A.) April 12, 1934, No. 11098. Convention date, April 25, 1933. [Classes 83 (ii) and 83 (iv)] In expanding a tube 11 into a pressure vessel, the sides of the hole are first cold rolled or expanded as at Fig. 3 to raise the yield point and increase hardness so that less expansion of tube and hole is subsequently required to make a tight joint. When the pressure vessel is an oil heater made of corrosion resisting alloy steel, e.g. of 18 per cent chromium, 8 per cent nickel and À12 per cent maximum of carbon, the reduced deformation thus lessens the damage to its corrosion resistant properties. The tube is expanded into position through the hand holes 14 of a return header bend. The hardness diminishes away from the periphery of the hole.

Filed: 1969-03-04
Abstract: 1,256,122. Axial-flow compressors; jet propulsion plant. GENERAL ELECTRIC CO. March 4, 1969 [March 6, 1968], No. 11449/69. Headings F1C, F1J and F1T. A compressor, e.g. in a turbofan engine as shown, comprises a rotor 34 having a row 36 of relatively long blades extending to an outer duct wall 38, and a row 62 of relatively short blades extending to a splitter ring 54. Air discharged at relatively low energy from the inner portion of blade row 36 is guided by vanes 56 into the blade row 62 where it received additional energy. Air discharged at relatively high energy from the remaining portion of the blade row 36 passes through flow straightening vanes 70, struts 72 and a propulsion nozzle 15. Flow straightening vanes 64 are inclined as shown in Fig. 3 with their concave surfaces facing generally towards the inner wall 80, to encourage the air to flow inwardly into inlet 46 of high-pressure compresser rotor 24. The leading edge of nacelle 42 forms a second splitter. During deceleration of the engine, the rotor 24 decelerates more rapidly than the rotor 34 and therefore is incapable of receiving all of the air leaving the vanes 64. However, the excess is readily diverted into nozzle 15 without substantial increase in back pressure and consequent stall at the vanes 64.

Title: Improved printing plates
IPC: B41C3/08
Filed: 1957-04-09
Abstract: 862,960. Printing-surfaces. PRINTING PLATES RESEARCH Inc. April 9, 1957 [April 9, 1956; April 8, 1957], No. 11562/57. Class 100(2) [Also in Group 1V(a)] A method of forming a printing plate comprises: providing in an impression mould of an original type forme a shell having a printing surface and an opposite surface; casting an epoxy resin composition having a viscosity not greater than 2000 centipoises at 25C. against the opposite surface; and curing the epoxy resin at a temperature below 125F. while retaining the mould against a substantially flat plane and separating the plate from the mould. This method gives a printing plate of the electrotype kind. An all plastic printing plate can be made by a modification of the method which comprises making a resin impression of an original type forme; separating the impression to give an impression mould; applying a parting agent to the impression mould; applying an epoxy resin composition having a viscosity not greater than 2000 centipoises at 25C. and curing the resin at a temperature below 125F. in the mould while retaining the mould against a substantially flat plane; and stripping the mould from the resulting epoxy resin printing plate. In one method of making the electrotype kind of plate, an impression mould 13a (Fig. 2B) having grained extremities is formed from a type forme having metal bearers 20 with grained faces. About one half inch of the bearer area 21 of the mould is masked off with tape 22 and a thin layer of silver is deposited chemically and then electroplated with copper 14a. Zinc, brass, aluminium or coarse copper electrodeposit is then applied or the copper is treated with ammonium hydroxide to increase the adhesion of the resin. The masking tape is removed and the cleared areas of copper are turned up along four edges to form a tray. The copper is treated with a sensitising agent (a liquid of lower specific gravity than the resin composition, for example ethyl or isopropyl alcohol) and the resin composition is poured into the tray which is maintained on a vacuum table until curing is effected. After the gelling stage the casting may be stripped from the mould and hardened at temperatures up to 200-220F. The all plastic plate can be prepared by taking the resinous flat impression mould, turning up the edges to form a tray, applying a parting agent (such as silicone, graphite lubricants, waxes, polyvinyl alcohol) and then casting and curing the epoxy resin. In making the impression mould there may be used waxes, latices, natural gums and resins such as poracumarone, vinyl acetate-vinyl chloride copolymers and modified alkyd resins. The epoxy resin compositions may contain a reactive diluent such as another epoxy resin, a polysulphide polymer, an allyl or phenyl glycidyl ether or alkyd polyamide and vinyl resins suitable fillers are aluminium, lead, zinc and iron powders, metal oxides and polyamides.

Abstract: 494,582. Telegraph exchange systems. LORENZ AKT.-GES., C. April 23, 1937, No. 11683. Convention date, April 23, 1936. [Class 40 (iii)] In a telegraph automatic exchange system, faulty setting of the selectors by telegraphic signals is prevented by arranging that if a selector receives more than ten impulses the test circuit is opened and the partially-established connection is released. In the system shown, closure of the calling key AT, Fig. 1, operates relays E, R causing the preselector, Fig. 2, to rotate until an idle group selector, Fig. 3, is reacted. Test relay T operates in series with relay C (i) and energizes H. The operation of contact t2 reverses the direction of current over wire b<11> causing the operation of relays S, N which reverse the. current over the calling loop a<1>, b<1> causing relay P<1> to operate and start the motor Mo. Impulses from dial contacts nsi are repeated by relay E to relay I (i), Fig. 3, to operate the vertical magnet H'. At the end of the digit, relay P (iii) releases and hunting takes place under the interaction of rotary magnet D' and relay I (ii) until relay P (i) (ii) again operates over wiper c. If a train of more than ten impulses is received, originating, for example, at transmitting key SK, contacts ko operated at the 10th step switch the lead a<11> over to relay Y (i) which operates on the 11th impulse to open the circuit of test relay P and to reverse the current over wire b<11> so that relays S, N, P<1>, E, R, T, C and the group selector release and motor Mo is stopped.
