Title: Improvements in photographic roll-film cameras
IPC: G03B19/04
Filed: 1929-02-22
Abstract: 329,051. Peters, W. A. Feb. 22, 1929. Cameras, roll-film.-In a folding camera of the type i n which the bellows are secured to a frame which is retracted into the casing when the camera is closed, and in which the film is contained in casings in a pocket at the base of the camera, locking means are provided to retain the rear door of the camera closed when the bellows are folded and when the film is extended, and to prevent the film casings being withdrawn from the pocket when the rear door is open. The locking means for the door comprises a lever 43, Fig. 3, pivoted at the base of the door frame and having an upturned end 47 held by a spring 50 under a stud 49 on the door. The outer end of the lever is provided with a thumbpiece 45 in a recess in the wall of the camera, and bears an upward projection 62 having a notch 63 and an extension piece 67. The bellows frame, 14, Fig. 1, is mounted on a swing- ing guide rail 30 which rests in a bracket 36 when the bellows are closed, and is then pressing on the extension piece 67 so that the lever 43 cannot be moved. When the film casing 25 is lifted from the pocket, a projection on it moves clear of the bell-crank lever 73, Fig. 3, which is moved outwards by an extension of the spring 50, causing a detent 78 on it to enter the notch 63 on the lever 43. To prevent the film casings being moved when the door is open, a projection on a spring- urged pivoted lever engages the upper casing. When the door is closed, an arm on the opposite end of the lever engages with the door and moves the projection out of the path of the casing.

Patent GB-1410976-A (GB)
Title: Valve actuators
IPC: F16K31/524
Filed: 1972-02-09
Abstract: 1410976 Valves TURNER MFG CO Ltd 6 Feb 1973 [9 Feb 1972] 6102/72 Heading F2V In a valve actuator for a tanker cargo valve 61 a cam plate 49, the position of which is controlled by a valve actuating rod 28 via a screw threaded sleeve 47, engages the end of a valve spool 65 in a control valve 53 which controls the supply to a fluid motor 25 which drives the valve actuating rod 28. The cam has three steps a, b and c and when the valve 61 is in its mid position flow of fluid to the motor is unrestricted. When the valve 61 is fully closed the cam face a sets the control valve spool in a position in which flow to the motor by-passes the spool, lifts ball valve 85 and flows via the restrictions formed by the end of a sleeve 86. Maximum pressure is thus available to unseat a stuck valve but the restricted flow allows the motor 25 to move only slowly until the cam face b engages the control valve to set it for unrestricted flow. When the valve 61 nears its fully open position cam face c engages the control valve which then cuts off all flow to the motor. The supply of fluid to the control valve 53 is under the control of a further valve 57, operated either manually or by solenoids 58, 59. For opening the cargo valve 61, valve 57 is set to position 1 shown in Fig. 3. When the valve is fully open valve 57 is set to position 2 which locks the actuator. To close the cargo valve, valve 57 is set to position 3 whereupon a reversed direction flow passes direct to the motor via line 94 but returns via line 89. Valve 53, however, will be in the position set by cam face c in which return flow is via a spring-loaded ball valve 76 and a restriction formed by a sleeve 80. Full pressure is thus available to move a valve stuck in the open position but again the restricted flow allows the motor 25 to move only slowly. When cam face b is engaged full flow is available through the spool to move the valve 61 quickly but when cam face a is engaged only a restricted flow is available to close the valve slowly on its seating. The maximum pressure applied to the motor is set by the adjustment of the spring loading on the ball valve 76 to a valve at which damage to the valve seat will not occur. Fig. 2 (not shown) illustrates a deck stand incorporating the valve actuation. The motor 25 drives the shaft 28 via reduction gears and a dog clutch for disengaging the motor drive so that a manual actuator can be applied to a keyed end of the shaft. The shaft 28 drives a reciprocating valve operating rod (23) via a rotary nut (18). Also incorporated are two microswitches (54), (55) for remotely indicating the position of the valve. The control valve 57, not shown in Fig. 3, may be mounted on the outside of the deck stand.

Title: Apparatus for throwing projectiles from aircraft
IPC: B64D1/04
Filed: 1926-03-08
Abstract: 248,777. Alkan, R., and Lesourd, G. March 9, 1925, [Convention date]. Bomb-dropping. - A main device for releasing a bomb from an aircraft is combined with an auxiliary device, which, according to its setting before the main releasing device is operated, determines whether the bomb drops with its fuze armed or unarmed. As shown, the bomb 18 is held by a hook A controlled by a cam 1, the spindle of which is provided with a crank 7 connected by a link 8 to a crank 6 on a main spindle 5. The safety member of the fuze is attached to a ring 19 held by a hook 2 in conjunction with a spring lever 3. the hook 2 being connected by a rod 4 to a spring 12, which maintains the hook 2 closed. The main spindle 5 has an eccentric 21 with a connecting rod 9 jointed to a lever 10 pivoted at 11 to the rod 4. An auxiliary spindle 13 has a crank 14 carrying a roller 15 normally maintained away from the path of the lever 10 by a spring 16. When the auxiliary spindle is in that position. and the main spindle is operated by a pull in the direction 22 on a crank 20 on the spindle, the cam 1 is operated and the bomb 18 dropped; but the lever 10 moves idly and the honk 2 remains closed, with the result that the safety member is pulled out of the fuze when the bomb drops, the fuze being thus armed. If, before the main spindle 5 is operated, the auxiliary spindle 13 is turned by means of a crank 23 and set to a position where the roller 15 lies m the path of the lever 10, then, when the spindle 5 is operated, the lever 10 bears on the roller 15 and moves the rod 4 and with it the hook 2, thereby releasing the ring 19. The bomb 18 is released immediately after this and drops with its fuze unarmed.

Title: Improvements relating to means for detecting gas leaks
IPC: G01M3/06
Filed: 1954-03-05
Abstract: 752,250. Testing gas meters. NORTH WESTERN GAS BOARD, and GODWIN, J. G. March 7, 1955 [March 5, 1954], No. 6459/54. Class 54. Means for detecting gas leaks comprises a device 11 for insertion between a gas supply and a meter, having ducts 14, 15 leading to a water container 16 and a cock 10 for diverting the gas flow to the container, the presence of bubbles indicating a leakage. The ducts 14, 15 are connected, e.g. by flexible tubes, to tubes 18, 19, respectively, mounted in a screw cover 17 for the container 16. When the cock 10 is rotated clockwise through 90 degrees from the position shown gas can flow from a connection 12 on the supply pipe to a connection 13 with the meter inlet and the pressure is the same in both ducts 14, 15. With the cock 10 in the position shown, however, gas can flow to the meter only through the container 16 so that if the meter outlet is closed bubbles indicate a leak in the meter. Opening the meter outlet enables leaks in the house fittings to be detected. The ducts 14, 15 may have different finishes, e.g. in brass and chrome, to match corresponding finishes on the tubes 18, 19. In an alternative embodiment, the water container is rigidly secured to the housing of an ordinary on-off cock and is connected by crossed ducts to, opposite sides of the latter.

Title: Improvements in matrix-composing and type-line casting machines
IPC: B41B11/52
Filed: 1939-02-27
Abstract: 525,742. Type-bar-making machines. TYPOGRAPH GES. Feb. 27, 1939. No. 6475. Convention date, Sept. 24, 1938. [Class 100 (iii)]  Moulds.-Relates to the casting of " finished " type-bars, which do not require trimming at the base owing to the base being formed by a longitudinal ledge 12, Fig. 8, at one side and two transverse feet at the ends, and the runner or waste-piece being sunk with respect to its point of attachment to the base. According to the invention the transverse feet 19 are not formed at the ends of the type-bar, as heretofore, but at points spaced from the ends, and, in the case of short type-bars, a single foot is formed at the centre. Imperfect casting of the ends of the line is thereby avoided, and a greater capacity for adjustment of the length of the line with the same mould is obtained. The transverse feet are formed by one or more waste-piece ejectors 17, Figs. 3 and 7, mounted in vertical recesses 16, Fig. 6, in the slotted intermediate plate 9, in which the tapered waste-piece is formed. The ejectors'17 are suitably formed on one face to produce the transverse feet, and have on the opposite face a wedge-shaped recess 18, into which the metal enters. After the casting, the intermediate plate 9 rises, to shear off the wastepiece, and to bring the ejection slot 14 for the type-bar in line with the mould. The wastepiece ejectors 17 are at first raised with the intermediate plate, but are arrested by a ledge on the mould. During the further rise of the intermediate plate" the inclined surfaces of the recesses 18 on the ejectors push the waste-piece out of the slot in the plate. The ejectors are formed with tapered portions 22 above the recesses 18 to avoid binding of the waste-piece on their sides.

Abstract: 443,464. Cutting-out presses. COOK, J. A., 75, Victoria Street, Westminster.-(Sachsische Cartonnagen-Maschinen.-Akt.-Ges. ; 21, Blasewitzer Strasse, Dresden, Germany) March 4, 1935, No. 6719. [Class 31 (i)] [See also Group XVI] In a cutting-out press a plurality of blanks are cut out from a single sheet of cardboard or like material at a single stroke by a rule-tool cutter and are left attached to the waste by small lugs. The cutter moves to and from a cooperating platen in a straight line with a short stroke and the sheets are fed to and from the cutting station simultaneously by automatic feeding means. The sheets are fed from a storage station 1 to a positioning station 1a by suckers and thence to the cutting station 2 and delivery station 3 by grippers 4. The grippers are mounted on a reciprocating rod 6 and are moved to and from the sheets by a rod 5 mounted on oscillating cranks 7, 8. The rod 6 is connected to a reciprocating bar 11 by a pin on the rod engaging a slot in a sleeve 11a and urged to the middle of the slot by springs. The gripper jaws 4a, 4b are closed by a spring 14 and the upper jaw 4b is opened at intervals by a bar having an inclined part which co-operates with a fixed wedge to lift the bar against a pin 16 on the jaw 4b when the bar is moved. A spring 22 holds the sheet 21 in place during cutting. In the form shown in Fig. 8, a sheet from a pile 39 passes between guides 1d into a vertical position in which it is positioned by stops 1b, 1c controlled by cams 23, 28. After cutting, the sheet passes to the delivery station where it is seized by swinging grippers or suckers 33, 34 and moved into a receiving-box 40.
