IPC: G03B17/34
Filed: 1925-10-12
Abstract: 242,256. PathÚ CinÚma, Anciens Etablissements PathÚ FrÞres. Oct. 29, 1924, [Convention date]. Change-boxes, selfcontained. - A film pack casing for flexible films provided with traction bands comprises (1) an envelope which contains the films and their bands and is foldable about a middle line to form front and rear compartments enclosing respectively the films and the bands, and (2) an independent removable partition plate to be inserted in the fold, and adapted to press the films against an exposure aperture in the front compartment. The envelope is intended for use once only; but the plate may be used repeatedly. In the form shown, several films each backed with paper extended to form a traction band 8 of narrower width, are inserted in a long black paper envelope 1 having an exposure aperture 2 with reinforced edges and a light-trapped withdrawal slot 4. In use, the envelope is folded as shown in Fig. 5, a metal partition plate 10 having a cylindrical end 11 and wire springs 12 is inserted in the fold, and the pack so formed is inserted in a holder formed of hinged parts 13, 14. The springs 12 abut on the part 13, with. out interfering with the rear compartment of the folded envelope 1, and press the films against the exposure aperture 2. Each film, after exposure, is drawn by its band 8 in the usual manner from the front to the rear compartment round the end 11. To facilitate removal of exposed films for development, a tab 15, Fig. 6, projecting through a slot in the back of the envelope 1. is connected to a slotted member 16 surrounding the bands 8 inside the envelope near the withdrawal slot 4. On pulling the tab in the direction indicated, the exposed films are pushed back halfway into the compartment containing the unexposed films owing to the engagement of the part 16 with shoulders 19 on the film backing 7, and maybe removed therefrom through the exposure aperture 2.

Title: Gyro Compasses
Inventor: CURTIS NORMAN
IPC: G01C19/38
Filed: 1966-06-08
Abstract: 1,183,034. Gyroscopic apparatus. SPERRY RAND Ltd. May 18, 1967 [June 8, 1966], No.25501/66. Heading G1C. A gyrocompass of the kind having a rotor mounted inside a sphere 11 the sphere having angular freedom about a vertical axis with respect to a vertical ring 12 which is in turn mounted with freedom about a horizontal axis in a follow-up ring 14, this follow-up ring also being rotatable about a vertical axis is provided with a follow-up motor 20 which in normal use rotates the vertical ring 12 to maintain this ring in a predetermined attitude with respect the sphere 11 as sensed by a pick-off 18, but which during start-up conditions may be used, under control of switches 23, 24, to rotate the follow-up ring 14 to bring the gyro rotor spin axis into approximate alignment with the meridian and then to the required tilt angle dependent on the ambient latitude. Stops 17 are provided to limit the angular movement between the sphere 11 and ring 12 and stops 25 limit movement between the rings 12, 14. Under start-up conditions the rotor is run to speed and the switch 24 set to the position marked "level". The switch 23 is operated and this causes the motor 20 to rotate the ring 14 to bring the rotor spin axis into approximate alignment with the meridian, as shown by an indicator mounted on the ring 14. During this movement the vertical ring 12 will tilt to the limit provided by the stops 25, i.e. about 45 degrees from the horizontal. The switch 23 is released and levelling commences to bring the rotor spin axis into the required tilt relative to the horizontal. In this procedure the motor 20 is provided with a signed dependent on a tilt signed from an electrolytic level 27 on the ring 12, a biasing signal related to the latitude derived from a computer 26 and an attenuated signal from the pick-off 18. The motor 20 rotates the ring 12 and sphere 11 through the stops 17 with a much smaller torque than used during operation of the switch 23 until the rotor spin axis reaches the desired tilt angle dependent on the signal supplied to the motor 20. The attenuated signal from the pick-off 18 prevents overshoot during this procedure and after setting for about one hour the compass is ready for use. Speed and latitude errors are corrected electrically by signals derived from a computer and fed to a torque 21 on the ring 12. The compass is made north seeking by the provision of a liquid ballistic with its centre of gravity displaced to the west side of the vertical axis of the sphere 11 to provide damping and the compass parts are preferably floated in an oilfilled chamber.

Title: Improvements in apparatus for controlling the delivery or discharge of high pressure air or gases
IPC: A61M16/10
Filed: 1921-09-29
Abstract: 190,807. Adams, F. H. Sept. 29, 1921. Inhalers. - In apparatus for administering anaesthetics the delivery of high-pressure air or gas from a container or other source is controlled by apparatus of the kind having a load-controlled valve which cuts the supply off when the pressure of the discharged gas rises unduly, the gas passing through. this valve passing to the outlet through an intermediate regulating chamber having outlets controlled by a second valve operated by the mechanism which operates the first valve. The valve is controlled by a diaphragm, and the gas passes to an expansible bag the inlet to which is automatically cut off on rise of pressure. In the apparatus shown, an intermediate receiver 10, Fig. 1, communicates through a valve-controlled tube 2 and a union tube 100 with a storage cylinder (not shown) of compressed gas, and communicates also through a pipe 30 controlled by a hand valve 55 with a bag 32, Fig. 4, connected with the pipe by a coupling 95. A valved pipe 86 leading from the receiver 10, and a valved pipe 88 leading to the pipe 30 communicate with a device for mixing the gas with chloroform or ether. The union 100 is formed with conical ends and with its nuts 17, 18 is reversible. The tube 2 is formed with inlet ports 66 controlled by a spring-pressed hollow valve 65 containing a reversible block 3 controlling the port 101 of the union 100. The valve is automatically closed by rise of pressure in the receiver 10 through a lazy-tongs pivoted at one end to a rod 7 secured to a diaphragm 19 covering the receiver and at the other end pivotally connected to a nut 6 screwed on the tube 2. The pressure at which the valve is closed is determined by springs 15, 16 surrounding the rod and abutting against a transverse member 71 of a gland 12 through which it passes. The valves may be positively actuated by Bowden wire mechanism in which the cable 75 is secured to the top of the rod 7 while the flexible tube is secured to a pillar 20, motion being communicated by a lever or a spring-controlled bolt having a pin entering one of a series of notches. The gas bag, Fig. 4, is enclosed within levers 33, 34 connected to a forked member 38 operating an inlet plug valve 44 through a link 42 in opposition to the action of levers 36 pressed by adjustable springs 39. The gas enters the bag through a stopped perforated silencing pipe, and passes out by a second pipe and a passage in' the valve casing to a mouthpiece connection. A spring-controlled piston or collapsible bellows. may replace the diaphragm, and the rotary plug valve of the gas bag may be replaced by a, valve of another kind.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03C21/00
Filed: 1964-06-23
Abstract: In the manufacture of flat glass, particularly in ribbon form, on a bath of molten tin at least some of the tin ions in the glass surface which has been in contact with the molten tin are replaced by hydrogen ions and then at least a proportion of the hydrogen ions are substituted by ions of another element.  The substitution of the tin ions is effected by treating the glass surface with a strong acid such as HCl for 1 minute at 100 DEG  C.  The hydrogen ions are then preferably replaced by ions having a similar ionic radius to the tin ions, such as lithium, calcium or zinc ions.  This latter substitution is effected by contacting the first treated glass surface with a saturated solution of the inorganic salt, e.g. calcium chloride, zinc chloride, for about five minutes at 130 DEG  C. If required this final salt may be one which upon further heat treatment of 500-600 DEG  C. develops a colour in the glass surface due to stannous ions still in the surface, such as manganese, copper or silver, or silver salts may be used to give a silvered surface. Copper or other elements may be used to form an electrically conducting layer.
