Title: Improvements in or relating to surface high speed craft
IPC: B63B1/24
Filed: 1935-06-13
Abstract: 458,110. Hydroplane vessels. WHITE & CO., Ltd., J. S., East Cowes, Isle of Wight, and HAMPDEN, G. C. E., The Old Mansion, Ewelme, Oxfordshire. June 13, 1935, No. 17053. [Class 113 (ii)] In hydroplane vessels in which the hull is supported by at least three downwardly directed struts B<1>, B<2>, B<3> carrying hydrofoil sets E<1> arranged transversely of the hull, the hydrofoils are arranged in forward echelon, that is the leading and trailing edges of any foil lie respectively further forward than the leading and trailing edges of the next lower foil. The angle of incidence of the higher foil may be greater than that of the lower foil to obtain greater initial lifting power. The hydrofoils may be backwardly and/or wholly or in part upwardly inclined. The leading edges of the struts may be backwardly inclined and may be either straight or convex. The leading edge of the strut may extend forward of the leading edge of the hydrofoil sets and may extend to the rearward of the hydrofoils.

Title: Improvements relating to gas turbines and fuel pumps operated thereby
IPC: F01D21/02
Filed: 1954-06-10
Abstract: 755,892. Gas turbine plant; turbines; centrifugal pumps. GENERAL ELECTRIC CO. June 10, 1954 [June 18, 1953], No. 17121/54. Classes 110(1) and 110(3) A gas turbine comprises a nozzle diaphragm arranged to direct motive fluid to rotor blades, an additional row of blades spaced radially from the main row and guide vanes separating the additional blades from the main blades, the additional row being supplied with motive fluid under overspeed conditions of the rotor to control the overspeed conditions. The turbinedriven aircraft fuel pump shown comprises a low-pressure stage 11 and a high-pressure stage 12, separately driven by contra-rotating turbine rotors 13 and 14 respectively. The rotors 13, 14 are driven by air, which may be derived from the compressor discharge of the aircraft gas turbine plant, supplied through an inlet manifold 20 to nozzle vanes 22 and thence through rotor blades 16d and 15. The area of flow between the blades 16a and the entrance angle of the blades are both kept to a minimum to control overspeeding at low pressure ratios. At high pressure ratios, the area of flow between the blades 16a is insufficient and some of the air then flows through blades 16b, after passing through axiallyextending radial vanes 23 which suppress the swirl imparted by the nozzle vanes 22. The acceleration imparted to the air on entering the blades 16b produces a braking action on the rotor 14. An additional braking action is obtained by the air striking the backs of the blades 16a. The blades 16a and 16b are separated by a shroud 16c. The blades 16b may extend axially or in the direction opposite to that shown in Fig. 3c. Projections 17 may be provided at the back of each blade 16b to reduce the exit area; they extend only to about half the height of the blades 16b, to allow air to pass to the blades 15. Overspeeding of rotor 13 is controlled by a drop in efficiency at overspeeding and by the air striking the backs of the blades 15. The rotors need not be counter-rotating and may be separated by stationary vanes.

Title: Improvements relating to fencing
Inventor: GOODALL CHARLES
IPC: B21F27/12
Filed: 1964-04-27
Abstract: 1,098,751. Making wire fencing. SWYFTITE Ltd. July 23, 1965 [April 27, 1964], No. 17359/64. Headings B3A and B3E. [Also in Division E1] In a method of making wire fencing connecting members or droppers 11 are laid across a plurality of parallel strands of wire 10 to which they are locked by elongated locking members 14. The droppers 11 are delivered by a feed conveyer (24), Fig. 2 (not shown), from which they drop on to notches in rollers 20 with loops 12 straddling the strands 10. A locking member 14 is then pushed through the loops 12, for example, by a pneumatc pusher. A beam structure 28 then descends lowering spring- loaded tools 33 to hold the droppers in fixed tools 35, 36. Further downward movement of the beam 28 causes tools 37 to force hook portions 13 on the end of the droppers downwards and outwards over the adjacent strands 10. The fencing is then advanced a predetermined distance by rotation of the rollers 20 and rollers (16) and (38), Fig. 2 (not shown), and the process repeated to secure another dropper. The completed wire is rolled on to a collapsible drum, Fig. 4, having a plurality of circumferentially spaced tubes 45 pivoted to links, in turn pivoted to a hand wheel 46 which can be rotated on a shaft 44 to vary the radial distance of the tubes 45 from the shaft 44 enabling a roll of fencing to be slid axially from the drum.

Title: Improvements in or relating to teleprinters
IPC: B41J33/60
Filed: 1958-05-30
Abstract: 880,603. Ink-ribbon mechanisms. SIEMENS & HALSKE, A. G. May 30, 1958 [May 31, 1957], No. 17433/58. Class 100(4) [Also.in Group XL(b)] In a teleprinter including a first mechanism for displacing a fork carrying an inking ribbon and a second mechanism by which the transmission of an identification signal can be controlled, the second mechanism is adapted to be changed from a first state to a second state in dependence on the change of the teleprinter from a first operating state to a second operating state, and the first mechanism is controlled by a control member controlling, or forming part of the second mechanism. When the teleprinter is in the receiving state, the operating bar I la during the movement to the left of the printing member 11 engages a projection on the lower side of a selected lever connected to the associated type lever to print the desired character. During this rearward movement of the member 11 an adjustable slotted bracket 29 engages a rod 14 secured to a lever 12 and carrying an arm 15 connected to a rotatable bell-crank 17 provided with a pin 19 engaging a slot 20 in an arm of a member 22 sliding on a rod 21 and secured to the fork 23 carrying the two-colour ribbon 24, which is raised to the position at which the characters are printed in black. In the receiving state a projection 12b on the lever 12 is not engaged by the bar 11a. When the teleprinter is in the transmitting state the operation of a transmitting member, e.g., by the character key of a keyboard, rocks an arm 4 and releases a latch member 3a on a lever 3 secured to a shaft 1 biased by a spring 2 so that the end 3b engages an extension 5b of a lever 5 which is moved downwards to free a latching projection 5a from engagement with a lateral extension 9a of a support arm 9 for a bail member 8. The shaft 1 is directly rocked by means operated when an identification signal is to be transmitted. A second support arm 10 for the bail 8 is biased by a spring 30 so that the member 8 is rocked counter clockwise and is latched by an arm 31. The bail 8 by its leftward movement engages the end 28a of a lever 28 which is rocked clockwise with the result that a pin 26 moves the lever 12 downwardly so that its projection 12b is engaged by the bar 11 a of the printing mechanism 11, and the increased travel of the pin 14 and the arm 15 raises the ribbon 24 to the position in which the characters are printed in red by the use of the lower half of the ribbon. The bail 8 is restored to its normal position in which the arm 9 is latched by the lever 5 by cams 33, 34 on the printing shaft 32 which respectively rock the latch 31 and engage an extension 10<SP>1</SP> of the arm 10.

Title: Shingling accumulator conveyer
IPC: B65G47/29
Filed: 1971-05-27
Abstract: 1329648 Transferring articles between endless conveyer belts; stacking articles EASTMAN KODAK CO 27 May 1971 [28 May 1970] 17616/71 Headings B8A and B8C Articles 12 of uniform size and each having a flange portion 11, are transferred from random spacing on a conveyer belt 14 to a shingled arrangement on a lower belt 15. As the leading article 12 topples from the belt 14 to the belt 15 it activates a light gate 18, 19. This causes extension of a stop 16 which at first supports the flange 11 of the article and subsequently engages the body of the article to hold it from further movement (Fig. 2, not shown). When the next succeeding article topples off the conveyer 14, the action of the gate 18, 19, results in extension of a second stop 16, and at the same time retraction of the first stop (Fig. 3). Further movement of the conveyer 15 brings the body of the leading article up against the second stop, and the second article then moves into close shingled abutment with the leading article. Further articles are joined to the group in this way, as further stops 16 are extended and retracted. When the last stop is retracted, no further stops are extended until when a further article is transferred, the first stop is again extended. The stops are successively extended and retracted by the action of a stepping switch (Fig. 5, not shown) connected to the output of the gate 18, 19.

Title: Film carrier for use in radiography
IPC: G03B42/02
Filed: 1958-12-02
Abstract: 915,392. Film carriers. ARVANETAKIS, K., and DONZIS, B. A. Dec. 2, 1958 [June 23, 1958; Sept. 15, 1958], No. 17736/62. Divided out of 915,391. Class 98 (1). A film carrier for use in radiographic work comprises a housing with an aperture for the entry of the radiographic rays, a supply reel and a take-up reel in said housing with means for guiding film from one to the other passing across said aperture; intensifier material, separate from but in contact with said film, is guided and fed with the film across the aperture at the same rate. In the form shown, the carrier comprises a box-like housing 6 mounted by brackets 8 so as to run on wheels 10. A supply reel 20 and take-up reel 21 are mounted on the ends of arms 19, and are urged apart by a toggle linkage 23 acted on by a spring 26. In passing from reel 20 to reel 21, the radiographic film 22 is guided by rollers 15 to pass across an aperture 7 in the housing wall. One of the rollers 15 is connected by a belt 17 to one of the wheels 10. In operation, the carrier is run along the outer surface of a pipe 12, a radioactive source being traversed along the inside of the pipe at the same rate, so that the source is always opposite the aperture 7. At the same time, the film is being unrolled across the aperture at the same rate. An endless belt 28 of intensifier material passes over the rollers 20, 21, 15, and thus is always positioned outside the film. Another endless belt 29 of intensifier material passes over rollers 15 only, and is positioned inside the film. Thus as the film passes across the opening 7 through which the exposure is made, it is contained between two belts of intensifier material. Since, however, these belts are moving with the film at the same speed, there is no relative movement between them, thus avoiding scratching of the film. Lead protector plates 30, 31 are provided within the housing, and sliding lead doors 32 can close the opening 7 when not in use.

Title: Manufacture of thorium oxide and thorium salts
IPC: C01F15/00
Filed: 1933-06-22
Abstract: A thorium oxide which readily dissolves to form salts when heated with acids is obtained by heating thorium oxalate at temperatures below 500 DEG  C.  Normal or reduced pressure may be used, and the time of heating should be so selected that "ageing" of the oxide formed is prevented.  In examples, the oxalate is heated at 300 DEG C. for 24 hrs. respectively in vacuo and at normal pressure, and thorium nitrate and chloride are produced by dissolving the oxide obtained in nitric and hydrochloric acids. In a reference to the art, it is stated that thorium oxide made by heating the oxalate to 500--600 DEG  C. is peptised by acids, and gives with nitric acid a colloidal solution of the oxide.
