Title: Improvements in method and apparatus for producing bellows folds in tubing
IPC: B21D15/06
Filed: 1928-10-25
Abstract: 324,134. Clifford, W. B. Oct. 25, 1928. Tubes.-A machine for corrugating a tube comprises a series of initially spaced dies 70, Fig. 2, within which the tube is held, the tube then being subjected to internal fluid pressure and compressed axially, while the dies slide freely in an axial direction to accommodate the changing length of the tube. The tube is closed at one end by a plug 62 which engages within a recess 54 in a screw-actuated ram 48 by which the axial pressure is applied. The other end of the tube is fitted with a cap 59 with which a ram 30 is engaged to make a fluid-tight joint at 44 this allowing fluid under pressure to be supplied by a hand-pump or by power to the interior of the tube. The thrust of the ram 30 is taken by a shoulder 103 on the head 80 engaging behind the cap 59. The dies comprise thin plates 70, 72, Fig. 6 hinged in pairs, and freely mounted on a rod 88 and on rods 84, 86, carried by hinged members 80, 82. The die pairs are normally separated by light leaf springs and are initially spaced on the work by pointed spacers 120 carried by a slide 130 which is withdrawn after sufficient internal pressure has been applied to set the dies on the tube. The dies, when closed are locked by clamps 110 to relieve the guide rods 84, 86 from thrust. Pivoted dogs 168, Fig. 4 are provided forming end stops for rods 164 on the end dies to limit the return of the dies under the influence of their interposed springs, on the dies being parted for the removal of the work. A stop 143 is also provided to limit the advance of the axial compressing ram. The work is removed from the dies by a forked member 150, Fig. 6 having a transverse pin 152 which functions as a fulcrum. The ram 30, Fig. 2, is moved up to the work by a handle which is retained by a pawl.

Filed: 1967-07-06
Abstract: 1,135,144. Photographic processing apparatus. VARITYPER CORP. July 6, 1967 [July 6, 1966], No. 31249/67. Heading G2A. The apparatus comprises a compartmented tank for processing fluid, drive means for sequentially passing the film through the compartments and an electrical actuator switch for ensuring that the drive means does not stop in a position which will prevent the tank being withdrawn from its housing. As shown in Fig.2, the housing is divided in the plane of the figure by a wall, on one side of which is a compartmented tank 30, removably held on rails, and on the other side of which is a chain drive. The chain drive turns sprockets having crank pins which are aligned, on sliding the tank 30 into the housing, with the wind pins 39 carried by tank 30 which turn sprockets 37 for advancing the film 42 through the compartments. The electrical circuit of the apparatus includes a normally open switch which, when closed will bypass the on-off switch of the apparatus, to maintain the chain drive in operation. A double-ended actuator Fig. 5 (not shown) is mounted to rotate with a drive-shaft such that it closes the by-pass switch whenever the wing pins 39 are in a position which would obstruct the withdrawal of the tank from the housing. The web 42 may be loaded in daylight from a cassette 57, which fits into a tray 58 on the housing, through an opening 61 on to a feed sprocket 41 where it may be observed through a red filter 62 positioned to determine that the web is loaded correctly. The feed sprocket 41 is linked to the drive means through an overload clutch. The web emerges through a slot having edges such that the web is held there-between by gravity.

Filed: 1959-09-14
Abstract: 893,942. Controlling jet propelled aircraft. SHORT BROS. & HARLAND Ltd. Sept. 7, 1960 [Sept. 14, 1959], No. 31250/59. Class 4. In jet lift aircraft having pitch stabilizing means in which controlling forces are exerted by the thrusts of jets of gas expelled from two directional nozzles, there is an arrangement wherein each nozzle is adjusted as to its cross-sectional area by a pair of shutters 38, 39 which are moved angularly in relation to the nozzle casing 37 towards or away from each other, and wherein the shutter assembly as a whole is rotatable within casing 37 to vary the angular direction of the jet thrust. One nozzle is located at the nose and the other at the tail of an aircraft fuselage. Fore- and-aft movement of the control column is transmitted by linkages to means for varying the apertures of the nozzles, and rotary movement of the rudder-bar column is transmitted by cords and/or linkages to the tail mounted rudder and to means for rotating each shutter assembly about a longitudinal axis, thereby controlling the yawing of the aircraft. Fig. 2, 4 and 5 are respectively a part-sectioned side elevation, a sectional plan view on line IV-IV of Fig. 2 and a section on the line V-V of Fig. 4, of the nozzle located at the tail of the aircraft. Attached to shutters 38, 39 are trunnions 381, 391, supported in bearings 371, 372 respectively, the former having attached to it a lever 40. Lever 41 is attached to the journal 392 of shutter 39. Levers 40, 41 are connected by links 42, 43 to brackets 44, 45 bolted to the arm 46 of the lever 46, 47 pivoted at 48. Arm 47 is connected by link 49 and pin 50 to a lever 21 of the linkage controlled by the control column, so that rocking of lever 21 will impart a rotational movement in relatively opposite senses to shutters 38, 39, thus varying the aperture 51. Fulcrum 48 of lever 46, 47 is carried by a bracket 52 integral with a sheave 53, mounted in bearings 54, 55 having a common axis coincident with the axis of shutters 38, 39. By means of cords attached to sheave 53 and to the linkage attached to the rudderbar column, rotary motion is imparted to member 52, 53 thereby rotating both shutters in the same sense about a longitudinal axis to adjust the direction of the line of thrust. The aircraft is provided also with wing-tip nozzles for control in roll, and the gases expelled from these nozzles and those located at the nose and tail are topped from the jet lift engines.
