Title: Improvements in or relating to Photo-Flash Devices
IPC: G03B15/04
Filed: 1966-05-24
Abstract: 1,154,352. Photographic cameras; photoflash sockets. EASTMAN KODAK CO. May 24, 1966 [May 24, 1965], No.21221/66. Heading G2A. A photographic camera (20, Fig. 1, not shown) having a rotatable socket (23) for a flash-cube (24) is further provided with means operatively connecting the film wind and shutter cocking mechanism with socket drive means so as to tension the drive means during film wind, the drive means running down to rotate the socket after an exposure has been made. A flash-cube is inserted in the socket so that the centre post (28) of the flash-cube receives a stabilizing spindle 56 Fig. 8 of the socket, two V-shaped retaining springs engage a pair of lugs on the centre post, and the base of the flash-cube depresses a control pin (60, Fig. 3, not shown) to automatically adjust the diaphragm aperture and the shutter speed for flash operation. An unexposed film frame is moved on to the picture taking axis by turning a lever 30 to the position shown in dotted lines. Rotation of this lever rotates the film take up spool (not shown) by means of gearing 33, 34, and also cocks the shutter by means of a foot 35 cocking a shutter striking plate 36. Simultaneously, a socket driving ring 100 is rotated 90 degrees counter-clockwise Fig. 8 by means of a hook 102 of a winding arm 50 engaging a pin 101 of the ring 100 and rotating it to the dotted line position shown against the bias of a helical drive spring. At the end of this rotation, the ring 100 is held in position by engagement of a tab 106 of a lever 107 with the skirt 108 of the ring 100, the lever 107 being held in position by engaging the plate 36. During rotation of the ring 100 a tab 115 of an indexing lever prevents rotation of the socket assembly (23) and an inserted package. The winding lever 30 is then returned to the solid line position by a spring 47. In making an exposure, a member 31 is depressed to the position of Fig. 10, thereby releasing the striking plate 36 to strike an ear 45 of the shutter blade, which thus uncaps the diaphragm aperture. The plate 36 also strikes a switch 97 to complete the flash circuit. Depression of the member 31 also causes an extension 121 thereof to move the tab 115 downwardly out of a notch 116 of the socket assembly (23). The socket does not rotate since a stop surface 109 of the extension 121 prevents the lever 107 from rotating out of engagement with the ring 100. After exposure, the upward movement of the member 31 disengages the surface 109 from contact with the lever 107 which therefore rotates out of contact with the ring 100, which in turn rotates clockwise Fig. 8 carrying with it the socket assembly (23). An arm 123 engages the next succeeding notch 116 and prevents the socket rotating through more than 90 degrees. When the member 31 is in its up position, and the socket assembly fully indexed, the tab 115 enters said succeeding notch 116, thereby displacing the arm 123 to take up the position shown in Fig. 10.

Title: Valve construction
IPC: F16K3/02
Filed: 1949-08-16
Abstract: 669,933. Valves. GROVE, M. H., and GROVE, J. E., (trading as FLUID CONTROL ENGINEERING CO.). Aug. 16, 1949 [Aug. 28, 1948], No. 21318/49. Class 135. A valve comprises a body having a flow passage, a ported valve member 17, Fig. 4, an annular sealing ring 60 surrounding the passage and slidably urged against the valve, an annular space 68 defined by radially spaced cylindrical surfaces on the body and sealing ring, and opposed shoulder faces on these two members, further sealing means 69 located in the annular space and screwing to prevent leakage between the sealing ring and body, the contacting surface 61 between the sealing ring and valve having a mean effective diameter corresponding to the mean effective diameter of the ring 69, and the latter is urged against one or the other shoulder face by line pressure or by pressure in the space 16 in the body about the sealing ring. The invention is applicable to rotary conical, cylindrical, or spherical valve constructions but is shown applied to a sliding gate valve 17, Fig. 2, wherein the sealing ring and valve contacting surfaces 61 are lapped. The fluid in the flow passage 11 or in the space 16, whichever is at the higher pressure, can flow past machined surfaces 63 or 67 and into the space 68, and the net pressure acting on the sealing ring 60 forces the latter against the closure element 17. Leather washers 71, 72 and a resilient, e.g. synthetic rubber, sealing ring. 69 are placed in the space 68, the ring 69 being slidable in the space according to the direction of the higher fluid pressure. Belleville washers 76 urge the ring 60 against the gate 17. The latter slides in guides 83 which are pressed against the edges of the gate by rubber bands 84. The gate is actuated by a handle 46 which engages in an apertured block 38 pivoted at 37 to brackets 36 upstanding from the valve casing, the plate being connected to the valve stem 21 by pivoted links 42. A spring-pressed ball detent engages depressions 49, 51 in the block 38 to hold the gate in the opened or closed positions. To balance the fluid pressure acting on the stem 21, the lower end of the gate constitutes a cylinder slidable over a piston 53 of the same diameter as the stem, and the space 59 between the piston and cylinder communicates with atmosphere through a passage 58. In a modification in which the gate is screw-actuated, a thrust ring is interposed between the casing and the sealing ring 60, and an annular wire spring of zig-zag form is interposed between the thrust and sealing rings.

Patent GB-906770-A (GB)
Title: Process and apparatus for removing sulphur from naphthalene
IPC: C07C7/148
Filed: 1960-06-17
Abstract: Naphthalene containing sulphur compounds is purified by treating with a Friedel-Crafts catalyst containing a metal under conditions which preclude cracking but result in the formation of organometallic compounds from the sulphur compounds and Friedel-Crafts catalyst, treating with water to convert the organometallic compounds to higher molecular weight products and separating these and recovering the naphthalene.  The process may be effected continuously.  Melted naphthalene is stirred with about 2% of aluminium chloride and reacted at about 120 DEG C. for 30 minutes e.g. in a heated coil then mixed with water, preferably an alkaline solution e.g. 10% sodium hydroxide.  The hydrocarbon phase is separated and distilled. Alternatively the naphthalene is treated in solution, e.g. benzene, for 5 minutes at about 60 DEG C. with 0.2% aluminium chloride and 5% of bleaching earth.  Water already present in the naphthalene and bleaching earth is sufficient and the solution is filtered and distilled.
