Title: Improvements in automatic stabilizers for air craft and water craft
IPC: B64C17/00
Filed: 1920-09-16
Abstract: 173,040. Vance, A. T., and Abbott, F. J. Sept. 16, 1920. Submarine vessels, special apparatus for steering. - Aircrait and watercraft (such as submarines) are balanced for lateral and longitudinal inclinations by automatic fluid-containing means which act through the usual hand-control lever when cable-sheaves mounted on the lever are locked against rotation thereon. As applied to aircraft, the hand control lever 3 can be turned about an axis 4 to operate the elevator through wires 7, 7', and about an axis 5 to operate the ailerons. For longitudinal balance, there is a tubular vessel 16 containing water, oil, or other fluid, bearing floats 25, 26 in its front and rear bent-up ends. The air spaces above the floats are connected by a pipe 23. Cross-heads 28, Fig. 6, on the float stems 27 are connected by a cable 29, which passes over pulleys 30 on the vessel 16 and has an interposed chain portion 31 passing around a sheave 32 on the hand-lever 3. When a lever 36 is released, so that a spring-controlled detent 34 engages teeth upon the sheave 32 and locks the sheave to the hand-lever 3, relative movement of the floats 25, 26, due to pitching of the craft, will result in movement of the handlever to adjust the elevator. For lateral balance there is a laterally-arranged vessel which is similar to the vessel 16 and mav be made in one with it so as to form a cross. The cable connecting the float-stems of the laterally-arranged vessel passes over a sheave 46, which can be locked against rotation on the hand-lever 3 by a detent 49 in one with the detent 34. The craft can be set to ascend or descend at a given angle, or to pursue a spiral course, by causing the detent 34 or 49 respectively to engage the appropriate notch on its sheave.

Abstract: 412,243. Fuel-injection pumps. SIMMS MOTOR UNITS, Ltd., and ATTWOOD, S. H., Percy Buildings, Gresse Street, London. Sept. 23, 1932, No. 26519. [Class 102 (i).] In a fuel-injection pump the plunger 1, Fig. 6, is formed with two diametrically opposite ports 3, 4, 5 of triangular shape. These ports communicate with the compression space by radial passages 6 and an axial passage 7 in the plunger, and the inclined edges 5 of the ports cooperate with inclined spill slots 12 in the barrel discharging into a space 13. The suction may take place from the space 13 through the slots 12 and an internal groove in the barrel communicating with the slots 12. Alternatively, the suction may take place from a separate suction chamber 11 through a port 14 in the barrel communicating with an internal groove in the barrel, which co-operates with the bases 4 of the plunger ports. The plunger is rotatable by means of a rack 15, Fig. 2, gearing with a wheel 16 having a splined engagement 17 with the plunger. In a multicylinder pump the rack is mounted in eccentric bearings 18 to permit disengagement for individual adjustment of the plungers.

Filed: 1934-09-17
Abstract: 427,077. Control systems for vacuum &c. discharge lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Sept. 17, 1934, No. 26683. Convention date, Sept. 25, 1933. [Class 38 (iv)] [See also Group XL] In order to reduce the warming period of a lamp containing the vapour of a difficultly vaporizable metal such as sodium, cadmium, magnesium, thallium or zinc, the lamp is connected in series with a lamp which has a shorter warming period and is temporarily short-circuited. As shown, the lamp 1, containing neon and sodium vapour, is connected in series with an inductance 3 and a lamp 4, which contains neon and is shunted by a switch 5 controlled by an electromagnetic time-lag relay 6. At starting the lamp 4 is short-circuited by the switch 5, so that a heavy current passes through the lamp 1 and reduces its warming period. At the end of that period the switch 5 is opened. A high impedance 7, in parallel with the lamp 4, prevents the lamp 1 from being extinguished when the switch 5 is opened.

Title: Sectional double-walled metal flue pipes
Inventor: STONE RICHARD LEHMAN
IPC: F16L9/18
Filed: 1966-06-15
Abstract: 1,093,662. Pipe joints; flue pipes. WALLACE MURRAY CORPORATION. June 15, 1966, No. 26726/66. Headings F2G and F2P. [Also in Division F4] A metal flue comprises a plurality of double walled pipe sections 10, 10a, adjacent sections being interconnected by mating female and male elements on the adjacent ends of said sections wherein the female element is formed by radially inwardly and outwardly extending interconnected annular grooved portions 20 and 21 in the outer and inner walls 12 and 11 respectively, and downwardly extending skirt portions 26 and 28, and the male element is formed by a return bend 19 at the end of the outer wall which is lapped by the flaired end 32 of the inner wall. The male element fits into the female element, the return bend 19 of the male element making a line contact with the outer wall groove portion 20. The joint is then secured by screws 37 passing through slots 38 in the female element into those holes of a plurality of holes 36 in the male element which register with said slots, Fig. 5 (not shown). The seamed or seamless tube forming the outer wall 12 of each section is preferably of galvanized iron and may be tapered slightly from the male element end to the female element end by forming it from a suitably shaped blank. The tube forming the inner wall is preferably of aluminium. Since the only positive connection between the inner and outer walls occurs at the female element end, the inner wall is free to expand due to  thermal changes at the male element end. Furthermore, the inner walls of the stacked pipe sections are not interconnected and hence do not act as weight or load-transmitting walls. In a modification, Figs. 6-8 (not shown), the annular grooved portions 20 and 21 on either or both the inner and outer walls of each pipe section may be replaced by spaced peripheral recesses (25). As illustrated in Figs. 9-15 (not shown), the stacked flue pipe sections are secured in a building structure at spaced intervals by pairs of rectangular plates (72) having semicircular cut-outs (74) which embrace the peripheral grooves 20 in the pipe sections, said plates having overlapping extension pieces 76. The plates are also provided with downwardly dependent lugs (78) which are bolted together to secure each pair of plates around the appropriate pipe section. The peripheral edges of the plates are then nailed, screwed or otherwise secured to transverse structural members of the building. The coaxial spaced wall flue construction eliminates the inherent fire hazard of hot flue pipes.

Title: Hydraulically operated indexable tool turret assembly
IPC: B23Q16/10
Filed: 1969-05-27
Abstract: 1,274,711. Tool turrets. KOVOSVIT. 27 May, 1969 [27 May, 1968], No. 26794/69. An hydraulically operated tool turret for indexing and locking a shaft carrying a plurality of tool holders 28 comprises an hydraulic cylinder 1 with hollow piston 10 therein and through which extends the shaft 6, a member 17 located in the piston is axially and rotatably movable on the shaft under hydraulic pressure when fluid is admitted to either of the ports 3 and 4 in the cylinder assembly. In operation hydraulic pressure moves the piston axially of the shaft 6 to engage a dog clutch constituted by engaging portion on the end of the member 17 and a member 23 secured to the shaft 6. Further axial displacement of the piston 10 causes axial displacement of the shaft, to disengage a further dog clutch 7, 8 until a thrust bearing 22 on the shaft abuts the end member 5 of the cylinder. Continued hydraulic pressure moves the piston relative to the shaft 6 and causes release of the spring ball locking means 18, 19 and 20 and the rotary movement of the member 17 by a roller 15 carried on the piston and engaging in a helical slot 16 in the member 17. The rotation of the shaft effects the indexing of the tool holders to present a fresh tool to the operative position where it is retained by the spring and ball 18, 20 engaging in the detent 29 in the member 17. The reversing of the fluid flow effects the reengagement of the dog clutch 7 and 8 and the subsequent disengagement of the clutch 17, 25 and the ball 18 from the detent 29 whereby the piston and member are returned to their original position, the spring ball locking means subsequently engaging in the detent 20.

Filed: 1971-04-19
Abstract: 1346925 Seaming non-metallic sheet material TELLEBORGS GUMMIFABKIKS AB 19 April 1971 [16 April 1970] 27115/71 Heading B5K [Also in Division B8] In a method of manufacturing from an elastomer, an endless conveyer belt of a thickness which is large in relation to the intended radius of curvature of the belt around the drive and end pulleys thereof, long lengths of conveyer belt material are manufactured and cut into short separate belt lengths the ends of which are spliced to form an endless conveyer belt having a carcass consisting of at least one longitudinally tension-reinforcing ply 15 and several transversely tension-reinforcing plies 17-19 and having a wear resistant cover 20 fixed to the transversely tension-reinforcing plies of the carcass. The invention is characterized in that in the manufacture of the carcass of the long conveyer belt lengths, the longitudinally tensionreinforcing ply or plies are made in continuous lengths while the transversely tension-reinforcing plies are made shorter lengths and are spaced apart along the longitudinally tension-reinforcing ply or plies, each space 10 between the lengths of the transversely tension-reinforcing plies corresponding to a splicing area 14 when the short belt lengths are spliced together in a series to form the manufactured endless belt. A further feature of the invention is that the longitudinally and transversely tension-reinforcing plies are vulcanized with spacer pieces 13 placed in the spaces and are removed after the vulcanization. Upon splicing the short belt lengths formed by cutting the long conveyer belt lengths and intended for the manufactured endless belt, a butt joint is formed between the ends of the longitudinally tension-reinforcing ply or plies. A piece of a tension-reinforcement ply 23 which with regard to strength, substantially corresponds to the longitudinal tension-reinforcement of the remaining part of the belt, is placed in each of the spaces between the ends of the transversely tension-reinforcing plies. While omitting at least one transversely tension-reinforcing ply, such a number of transversely tension-reinforcing ply pieces 24, 25, are inserted on top of each other in each of the spaces that the conveyer belt carcass has a substantially uniform thickness within all parts of the composite conveyer belt. In cutting the long conveyer belt length into short lengths, the longitudinally tension-reinforcing ply or plies are cut obliquely across the conveyer belt. Fig. 2 shows two ends of two belt lengths in alignment for splicing and it shows the alignment of the inserted reinforcement ply 23, the additional transversely reinforcing ply pieces 24, 25, and the portion of the wear resistant cover 20 which covers over the joint. In addition there are thin rubber interlayer portions 21, 22, and 26, inserted in, and covering the joint.
