Title: Improvements in apparatus for taking torpedoes on board and placing them in the firing tubes of submarines
IPC: F41F3/08
Filed: 1923-12-31
Abstract: 211,107. Schneider et Cie. Feb. 6, 1923, [Convention date]. Handling torpedoes.-An apparatus for receiving torpedoes on board a submarine and leading them to the torpedo tubes comprises a cradle B, Fig. 1, for holding the torpedo A, and two tracks C, D for guiding the cradle down to the tubes. The first track C is mounted on a horizontal pivot c<6>, and is initially held in a horizontal position by means of a pin passed through a hole in the rear end of the track and through the lower hole c<14> of a rear support c<12>. In this position, it receives the cradle in which the torpedo A is deposited ; and the cradle is connected by a cable to a windlass K. The track C is then unlocked from the support c<12> and tilted about the pivot c<6> to bring it in line with the second track D, which is mounted in a sloping position on supports d<3>, d<4>, d<5>; and the track C is again locked to the support c<12>. The windlass is operated to let the cradle slide or roll down on to the second track D. A pin g<1> or h' at the front end of the cradle is then engaged with a bearing G, Fig. 1, or H, Fig. 3, respectively, and the rear end of the cradle is held up by a block tackle or otherwise, while the track D is removed. The cradle is then lowered down flat on the floor or slightly above it according to the bearing G or H used. In the latter case, the torpedo is exactly in line with the tube L. The torpedo is inserted in the tube by any suitable means. The cradle may be provided with rollers for supporting the torpedo; and these rollers may be fixed in the operative position as shown at I, Fig. 8, or adapted to be moved out of action as shown at J. The cradle may be slidably carried by hooks b', Fig. 9, resting on rails c<l> on the tracks, or may be provided with rollers b<4>, Fig. 5, running on rails c<2> on the tracks. A clamping device E is provided on the cradle for securing it at any position on the tracks; and for safety in case of the windlass cable breaking, this cable f<2>, Fig. 6, is connected to an automatic brake f<1>, which grips a rail c<16> on the tracks if the tension of the cable fails.

Title: Improvements in or connected with wings for aircraft
IPC: B64C3/00
Filed: 1927-12-05
Abstract: 306,220. Choriton, A. E. L., Haig, R. A. de H., and Stieger, H. J. Dec. 5, 1927. Planes, construction of.- To take up torsional stresses on the spars of cantilever wings for aircraft, each spar, comprising two booms connected by a web, is strengthened by triangular bracings on opposite sides of the spar with the base of each triangle terminated at the booms and the apices being connected together in pairs or stayed apart and also stayed in line on each side of the spar by longitudinal bracings. Fig. 2 shows a spar having booms A, B braced by tension members to opposite ends of struts D passing freely through the web of the spar, the ends of the struts being braced also by longitudinal wires K, L. The struts D may be perpendicular to or inclined to the web. Fig. 9 shows an alternative construction involving fewer tension members. The struts D in this construction may be omitted if the triangular bracings are made capable of taking both tension and compression stresses. Fig. 5 shows a modification in which the triangular bracing is connected to points on the ribs which are strengthened by struts D, - - D4 extending respectively to points on the lower and upper sides of the rib. Two similar systems of bracing overlapping one another also may be employed. Fig. 7 shows a further modification wherein the ribs are strengthened by struts D1, D3, D5, D6, D7, D8 and braced as shown, or the outer wires E, F<x>, F<1>x may be omitted in each bay. The bracings are of heavier gauge material in the bays near the root of the wing than in the bays near the tips.

Filed: 1977-08-04
Abstract: 1537226 Valves for closing engine air inlets BR LORNE RESOURCES Ltd 4 Aug 1977 [16 Dec 1976] 32777/77 Heading F1B [Also in Division F2] In a gate valve for closing an engine air manifold in the event of an external emergency, the gate 32 is normally held open by a pair of tension springs (122) and is closed by fluid-pressure admitted along the bores 94 of a pair of fixed pistons 90 engaged in cylinders 52 fixed internally of the gate. Each cylinder 52 is closed by a plug 56 against which the actuating fluid-pressure reacts. Each side of the gate has a longer and shorter guide pad 66a, 66b, which co-operates with guide strips (62), each having a longer and shorter recess 62a, 62b into which the pads engage in the fully closed position. In the open position vibration of the gate is prevented by a spring-biased pad 78 engaging one side of the gate. In a modification the gate has a single actuating cylinder and biasing spring.

Title: A device for use in percussion mechanisms
IPC: B25D17/24
Filed: 1964-08-12
Abstract: 1,015,380. Percussive drills. K. E. A. JOELSON. Aug. 12, 1964 [Aug. 21, 1963], No. 32901/64. Heading B4C. A percussive drill comprises a working piston 8 movable in a cylinder 6 and an elastic damping means 28 to absorb the kinetic energy of the piston at the end of its working stroke if the piston is not stopped by contact with the object to be struck. The damping means is in the form of a light casing member 25 slidable on enlarged portions 26, 26 of the piston 8 so as to define a chamber 28, the member being retained on the piston by means of a split ring 30. In operation, the working piston is moved downwardly by means of a column of liquid trapped between a drive piston 4 and the working piston, the drive piston being moved downwardly by means of an eccentric 2 rotated via an hydraulic motor 2a; the motor is driven, via liquid fed from a tank 11, by a pump 14, the pump also feeding liquid via pipes 21, 22, the interior of a housing 1 and a check valve 5, into the space between the pistons. Liquid is also fed via a port 29 in the piston 8 into the chamber 28 so that if the piston for some reason does not strike the end of the tool 24 and overruns, the member 25 strikes a shoulder 31 on the housing 1 and such impact is cushioned as the liquid in the chamber 28 is forced through port 29 into a channel 19 via a port 9; the area of the port 29 may be adjustable. The drive piston is returned by means of a spring 7 and the piston 8 by means of suction drawn through a pipe 16, connected, via a valve 17, with the low-pressure side of an ejector 18 in the liquid feed pipe 21, 22.

Abstract: 670,632. Picking-motions for looms. HOUDAILLE - HERSHEY CORPORATION. Dec. 21, 1948 [July 9, 1948], No. 32947/48. Class 142(iii) A picking-motion, which moves the picker in a substantially straight line path, comprises a bracket secured to the rock shaft and a bracket secured to the picking stick, the brackets being connected by two links. A bracket 13 is attached by links 14, 15 to a bracket 12 mounted on the rock shaft 10. The effective length of the link 15 may be varied by turning an eccentric bolt 16 securing the link to the bracket 12. After picking, the inward movement of the picking stick is checked by a hydraulic device 20, described in Specification 670.634, and comprising a piston 22 and a cylinder 21 secured to the brackets 13 and 12 respectively. A torsion spring 40 then urges the picking stick outwards until a spring stop device, described in Specification 669,325, comprising a spring 41, arm 42, and fixed pin 44, holds the picking stick in a position where it will be engaged by a returning shuttle. The final outward movement of the picking stick is checked by the device 20.
