Title: Improvements in gas-analysing apparatus
IPC: G01N7/08
Filed: 1926-08-24
Abstract: 257,609. Svenska Aktiebolaget Mono. Aug. 28, 1925, [Convention date]. Gas analysis. - In a gas-analysing apparatus, particularly for testing flue gases, in which an oscillating column of mercury is employed to drive a measured quantity of the gas under test into a liquid by which some of the constituents of the gas are absorbed, the absorption liquid serves as a sealing liquid for the gas bell which measures the amount of gas remaining after absorption, and is used also in the pump which effects the movements of the mercury, the renewal of the absorption liquid in the measuring- vessel after each analysis being effected by the pump. As shown in the figure, absorbing liquid, e.g. caustic potash, in a tank 29 is driven by a pump 1 through a throttle valve 2 into a chamber 3, connected through a mercury seal with chambers 4, 5, and having therein a chamber 8 containing mercury into which dips a tube 9 leading through the top of the chamber 3 into the chamber 4. The chamber 5 is connected by a pipe 7 to the source from which the gas is to be drawn, and through a pipe 15, mercury seal 16, pipe 17, reversing device 18, stove 19, and pipe 20 with a measuring-vessel 11 fitted with a measuring- bell 24 and connected by a pipe 10 with the chamber 4. As the absorbing liquid is pumped into the chamber 3, the pressure therein rises, mercury is driven therefrom into the chambers 4, 5 and into a pipe 6 communicating therewith, whilst the mercury in the chamber 8 is driven through the tube 9 into the vessel 4. When the chamber 8 has emptied, the absorbing liquid has access through the pipe 9 to the chamber 4, which it fills, the syphon tube 10 then supplying fresh absorbing liquid to the vessel 11, that displaced over the rim 28 being returned through a pipe 13 to the chamber 29. The pressure in the chamber 3 having now fallen, the mercury in the chambers 4, 5 and in the pipe 6 begins to flow back into the chamber 5 through the pipe 7, until the level of mercury in the chamber 3 having risen above the syphon 14, the chamber 8 is refilled, and pressure again rises in the chamber 3, whereupon the mercury, again rising in the chamber 5, forces a quantity of gas through the connections 15 - - 20 into the vessel 11, through the absorbing liquid, and by way of the pipes 21 - - 23 into the atmosphere, until the rise of mercury in the pipe 6 seals the outlet 23. The bell 24 then rises to an extent determined by the amount of gas not absorbed, and the cycle of operations is complete. The whole apparatus, as far as is practicable, is made of metal.

Abstract: 422,405. Projectile fuzes. SOC. ANON. ARTURO JUNGHANS FABBRICA D'OROLOGERIA, Gindecca, Venice, Italy. July 17, 1934, No. 20904. Convention date, Nov. 24, 1933. [Class 9 (i)] In combined clockwork and directimpact percussion fuzes, the directaction percussion bolt c is arranged to release the spring striker of the clockwork fuze independently of the clockwork. As shown, the clockwork fuze comprises in known manner a spindle d provided with an arm e adapted to bear on the rim of the timing disc a and adapted, when the arm falls in a notch in the timing disc at the appointed time, to release a lever f, which in turn releases the spring striker (not shown). Now, the lower end of the spindle d is mounted in a plate g which is normally held in place by a spring hook h. When the bolt c is driven in by direct impact, its inner pointed end bears on a conical piece h<2> on the spring hook and deflects this hook away from the plate g, whereupon centrifugal force causes the spindle d to move outwards and release the lever f.

Title: Photographic reflex camera
Inventor: STEISSLINGER KURT
IPC: G03B19/12
Filed: 1964-05-22
Abstract: 1,075,652. Photographic reflex cameras. EASTMAN KODAK CO. May 22, 1964, No. 21173 / 64. Heading G2A. A single lens reflex camera is provided with a device for locking a cover flap on mirror in an operative position, which device comprises a latch 53 urged away from its locking position by a first spring 56, and actuating means coupled to the latch 53 through a lost motion connection and including a second stronger spring 60, the actuating means being movable between a first position in which the spring 60 holds the latch 53 in its locking position and a second position in which the spring 60 is disabled so that the weaker spring 56 can move the latch 53 into its unlocking position. The actuating means comprises a lever 64 coupled by a pin and slot connection, to an arm 59, the lever 64 being pivotally mounted and the arm 59 and the latch 53 being fixedly mounted on a common shaft 51. The spring 60 arranged between the lever 64 and the arm 59 rotatably urges these members towards each other. The locking device is incorporated in the single lens reflex camera disclosed in Specification 1, 075, 651 and is operated, on movement of the control slide 34, by a pin 34c mounted on the slide 34 and engaging the lever 64. As the control slide 34 moves down, the lever 64 follows the pin 34e under the action of the spring 60, until the pin 67 on the arm 59 reaches the end of the slot 68 in the lever 64. The spring 60 is thus rendered ineffective and the spring 56 moves the latch 53 away from its locking position. On the return, upward movement, of the control slide 34, the pin 34e moves the lever 64, the arm 59, the shaft 51 and the latch 53 as a unit against the bias of the spring 56 until the latch engages the cover flap or mirror. The final portion of the upward movement of the slide 34 pivots the lever 64 so that the end of the slot 68 is withdrawn from the pin 67. The arm 59, the shaft 51 and the latch 53 are then urged towards the cover flap or mirror by the spring 60.

Abstract: 757,303. Automatic gramophones. HANSEN, H. C. Sept. 10, 1951 [May 12, 1951], No. 21331/51. Class 40(2) In an automatic gramophone for playing records of mixed sizes, a record-size feeler moves in a path in engagement with the surface of the next record to be supplied to the playing position, and is adapted to be subjected to resistance against its movement in such portion of its travel path that lies in the orbit of the edge of the particular size record with which the feeler is in contact. The automatic gramophone described is substantially the same as that described in Specification 757,379 but differs in the respect that the pick-up arm 112 is provided with a low-friction roller 400 having a surface rising above that of a high-friction member 403. During an outward movement of the arm 112 under the control of a cam-disc 144, the arm 112 moves outwardly without resistance until the roller 400 leaves the edge of the lowermost record of the stack. Should the said lowermost record be of one of the two smaller sizes, the movement of the arm 112 is arrested, so that the cam-follower 252 pushes aside spring 284 1  or 284 2  at the entrance of the cam track appropriate to the size of record detected. At this stage the arm 112 is moved outwardly a small amount, so that the high-friction member 403 passes beyond the edge of the record, whereupon an inward movement which follows unseats the record from the centre post.
