Abstract: 259,997. Fr÷b, W., (Assignee of Kreyser, K. W.). Oct. 16, 1925, [Convention date]. Sliding valves; casings.-A slide stop valve is provided with tubular sliding seats i, Figs. 1 and 3, which close upon opposite sides of the valve disc b in its closed position, as shown in Fig. 3, and upon each other in the open positions, as shown in Fig. 1, in order to provide a smooth passage. For this purpose the stem f of the valve is formed with a quick pitch screw-thread engaging an internal thread in the operating spindle e. The sliding seats i are connected bv levers and links p, o with a nut m having a thread of slower pitch engaging an external thread on the spindle e. In the closed position a stop pin u on one of the sliding seats engages an aperture in the valve disk b as shown in Fig. 3. In the opening movement the initial rotation of the hand wheel d causes the spindle e to move downwards under the action of the spring t, and the nut m to move upwords relatively to the spindle c but a slower rate, and consequently downwards relatively to the casing, thereby separating the sliding seats in opposite directions. When the downward movement of the hand wheel d is arrested by the bridge member r further rotation draws up the valve disk b quickly to the open position accompanied by an upward movement of the nut m which causes the sliding seats to move inwards and abut upon each other, as shown in Fig. 1. The reverse action takes place in closing the valve.

Abstract: 364,582. Bottling in inert atmospheres. DEHN, F. B., 103, Kingsway, London.-(Mallinckrodt Chemical Works; 3600, North 2nd Street, St. Louis, Missouri, U.S.A.) Sept. 1, 1930, No. 26077. [Class 125 (ii).] Relates to machines for filling cans &c. with ether &c. in an atmosphere of inert gas. According to the invention the cans are introduced into an atmosphere of inert gas and evacuated, filled and closed in said atmosphere. The apparatus employed comprises presses P, K on a table T, a main shaft 7 and crank shaft 5 interconnected by gearing, and a cam shaft C chain driven from loose gear 13, having a clutch 19. A chambered ring R is intermittently driven from the shaft C through a ratchet and pawl M. An airtight evacuating and charging shoe S co-operates with the ring R, and keeps the chambers in the ring fluidtight. The cans &c. move intermittently with the ring R which is enclosed in a chamber B filled with nitrogen &c., and are repeatedly evacuated and recharged with the gas before they are filled with ether by the filling machine F. The cap shaping and punching press P is operated from the shaft 5. In operation the valve 31 is opened to admit nitrogen to the chamber B and air is forced out at the trap 35. Ether &c. enters the filler F, through the inlet 155 and is maintained at constant level by the overflow 157. Delivery and take-off conveyers 121, 273 are now started. Cans enter through a pipe 119 and a pedal 69 is operated to close the clutch 19. The presses P, K operate once for every revolution of the cam-shaft C. Closure of the clutch 19 causes intermittent movement of the ring R and delivery of cans N into pockets therein. As the cans reach positions V, W, X they are evacuated and filled with nitrogen under the shoe S and then they pass out from under the shoe to automatically fill with ether from dippers 165. The filled can then moves to the press K where it is provided with a loose cap, and thence to the press P for sealing. At the position Z under the shoe S the capped and filled cans are dropped through a tube 269 to the conveyer 273. One further movement of the ring R brings an empty chamber 81 to the position where it is again loaded. All the operations of filling, capping and closing are synchronized from the cam-shaft C. The evacuating pipes 147, 149, 151 are connected to a suitable exhausting device {not shown), and are connected to openings A, E, O in the shoe S. Specification 345,001 is referred to.
