Non-return valves V1, V2, V3 are provided on the inlet 11, the outlet 12 and the outlet 15. The portion 141 of piston 14 is of smaller diameter than portion 142 to provide a chamber B which is connected to the inside of the cylinder above the portion 142 by a number of holes 143 provided in the member 142. In operation valves V1, V2 are opened and V3 closed, the piston 14 is reciprocated so that the oil is circulated from the transformer, and when the cylinder 13 is filled with oil the piston 14 is stopped in the position indicated P, valves V1, V2 are closed and V3 opened. The piston is then pulled down slowly so that the oil in chamber B is forced up through the holes 143 and becomes degasified. On the up stroke of the piston the released gas is forced through outlet 15 and via valve V3 to a gas analyser GC. When sufficient gas has been collected the operation is complete. The piston may be replaced by a bellows and a silica gel filter may be arranged in series with valve V3. The various components may be assembled in a single unit which can be assembled with the transformer. A motor or electromagnetic means may be used to operate the device.

Filed: 1958-12-29
Abstract: 855,255. Lifts. OTIS ELEVATOR CO. Dec. 29, 1958, No. 41851/58. Class 78 (3). [Also in Group XXV] In an automatic lift system movement of the car doors to a position in which they are nearly closed discharges a capacitor through a relay which starts the car before the doors finally close, and movement of the car to a position in advance of a landing at which the car is stopping discharges another capacitor through a relay which commences opening of the doors before the car has stopped. Contacts DCL1, DOL, DEL and DCL2 are operated by movement of the door closing motor. Motor DMA, DMF effects movement of the doors, and motor GF, GA, MA operates the winding sheave HS which is subjected to the action of a magneticallyreleasable brake B. Assuming a car to be standing at a floor and the doors to be closing relay GS is energized over contacts DCL2, thereby closing contacts GS1 and causing capacitor C2 to discharge through and temporarily energize relays UX, HX. The consequent closing of contacts UX2 energize relays U and H, thereby energizing the hoist motor field winding GF over contacts U2 and releasing brake B over contacts H1. When the doors are fully closed switch DCL1 opens, thereby deenergizing relay DC which open-circuits the armature DMA over contacts DC2, DC3. As the car moves contacts GS1, 2E2 are opened and contacts GS2, 2E1 are closed (by means, not shown), thereby charging capacitors C1 and C2. When the car approaches a floor at which it is to stop, contacts 2E2 are closed, thereby causing capacitor C1 to discharge through and temporarily energize relay DO which, over contacts DO2, D03 starts the door operating motor DMA. In the event of the capacitor C1 discharging before the car reaches a predetermined position adjacent the landing or capacitor C2 discharging before the doors fully close, the door or car movement is terminated. The Specification describes a door-operating mechanism (see Group XXV). Specification 711,515 is referred to.
