Title: Improvements in or relating to back-pressure bottling apparatus
IPC: B67C3/26
Filed: 1958-01-28
Abstract: 838,918. Bottling. KAISER, B., and HOLSTEIN & KAPPERT MASCHINENFABRIK PHOENIX G.m.b.H. Jan. 28, 1958 [Jan. 31, 1957; June 22, 1957], No. 2852/58. Class 125(2). In a rotating counterpressure bottling machine having filling heads 1 disposed around an annular reservoir 31 and including liquid and gas valves 7, 17 and a gas tube 11, 18 extending through liquid valve 7, the gas valve 17 is located within the liquid valve, i.e. at a low level, to diminish the volume of gas tube below the gas valve and hence to diminish the amount of liquid running from the gas tube when a filled bottle has been snifted. The upper part 11 of the gas tube is integral with valve 7 and has a flange 27 on which bears a compression spring 8 which opens valve 7 when the pressures in the bottle and reservoir are equalized. Valve 17 is carried on the lower end of a longitudinally grooved rod 12 within tube 11 and terminating in two spaced flanges 13. Valve 17 is normally held closed by the reservoir pressure but is held open by a spring 30 after it has been lifted by a lever 23 moved by a fixed trip to bear on the upper flange 13. A spring arm 24, in this position of lever 23, bears on an abutment 25 carried by flange 27 and prevents opening of valve 7 until the bottle has been fully counterpressured. In operation, a bottle is raised to engage a sealing gasket 21 in the head and then lever 23 is actuated to lift rod 12 and the gas valve, the bottle being counterpressured. Lever 23 is then moved to a middle position, thus freeing arm 24 from abutment 25 and liquid valve 7 is opened by spring 8. Liquid runs into the bottle, being directed in an annular sheet by conical surfaces 50, 20 on gas tube 18. When filling is complete, trapped gas is prevented from rising into the reservoir from the bottle neck through the liquid passage by a fine screen 6 and lever 23 is lowered to close the gas valve. Snift valve 22 is then actuated, the bottle is lowered, and lever 23 is restored to an intermediate position. Fine passages 56, 57 allow complete draining of the reservoir after removal of the filling heads.

Title: Improvements in resilient telescopic devices for aircraft alighting gear
Inventor: NICHOLL EDWARD JAMES
IPC: F16F5/00
Filed: 1950-02-06
Abstract: 685,469. Replenishing liquid - springs. DOWTY EQUIPMENT, Ltd. Feb. 6, 1951 [Feb. 6, 1950], No. 3032/50. Class 108 (iii). [Also in Group XXIX] A liquid spring, which may be of the kind described in Specifications 560,047 and 560,048, communicates with an external source of liquid pressure via a loaded valve 27, which is urged to unseat by the combined pressures of the load and of the external source, and is caused to seat under the action of rapid increased pressure within the liquid spring, there being a restricted passage 33 across the valve 27 when the latter is unseated, which permits seepage of liquid from the spring to the external source or vice-versa. In the constructions shown, as applied to an aircraft landing gear, the valve 27 is loaded by the action of a spring 31 and plunger 30, and has an annular resilient seating 28. At 25 is connected a pipe-line from the external source of liquid pressure, which may comprise the usual aircraft hydraulic system pump and reservoir. A combined reducing and relief valve (see Group XXIX) may be provided to bring the pressure of the system down to the normal pressure within the spring under airborne conditions. This valve also permits liquid to escape from the spring to the reservoir if more than a predetermined pressure exists in the spring, but if the hydraulic system pressure is equal to the normal spring pressure, it may be replaced by a relief valve. The body 17 of the valve 27 is connected by a passage 16 through the liquid-spring plunger 13 with the pressure cylinder. In operation, when the aircraft is airborne, the combined pressure of liquid from the line 25 and spring 31, maintains the valve 27 open, in opposition to the action of liquid pressure in the liquid-spring cylinder. Liquid can thus pass from the line to the spring to make good any pressure loss in the latter due, for example, to temperature changes. If the pressure in the spring is above a predetermined amount, the relief valve permits flow from the spring to the reservoir of the hydraulic system.
