Title: Improvements in and connected with bulkhead and like door installations for ships
IPC: B63B19/00
Filed: 1921-06-04
Abstract: 185,503. Pike, F. J., and Neville, H. June 4, 1921. Operating doors hydraulically, by floats and the like, by weights, and by toothed-gear mechanism; checks.-In door-operating mechanism for ships' bulkhead doors of the self-closing type in which a clutch in the door-opening mechanism is under the control of a piston, the cylinder of the piston is in communication with a source of pressure due to a static head, such as by a pipe communicating with the sea through the skin of the ship, or with an elevated tank or reservoir belonging to one of the water services of the ship. By means of a control valve, manually or float controlled, the clutch may be disconnected from the dooroperating mechanism and allowed to fall or close by gravity or under the action of weights. Fig. 1 shows a control arrangement for a single door. The door is lifted into the open position by a hand-operated worm shaft h gearing with a wormwheel g loose on the door-operating shaft f but operatively secured to it by a clutch member k. The member k is slidably keyed to the shaft f and maintained in engagement with a clutch element on the worm-wheel by a spring s'. In this position, the valve w is put to exhaust and the spring s forces the link o downwardly, the head m on the rod n compressing the spring s<1>. To close the door, the valve w is moved either locally or from a central control station 8 to place its port in communication with a sea-pipe y and with the cylinder r. The piston q is thereby lifted, operating the link o to relax the pressure on the spring s'. The door is now free to fall. its closing movement being checked by the usual dash-pot check 4, 5. The door-opening mechanism is restored to operative position by moving the valve w to the exhaust again. The plug cock w may be duplicated, a second control valve leading to a series of other doors which may be similarly controlled. A slide valve may be substituted for the plug cock. In a further modification, the piston q may be directly connected with the member m. A modification is also described in which the lever connected to the member m is operated by a piston, the cylinder of which is in communication with an oil chamber, a slide valve controlled from the bridge admitting pressure fluid to the control piston. This arrangement also provides for local hand-control. The arrangement shown in Fig. 6 provides for the door to be opened by the hand-gear after the door has been closed by the exercise of the central or other control. By raising the hand-lever 25, the rod p is moved down against the action of the spring 23 to close the clutch, and with the parts in this position the door can be raised by the manual operation of the door-opening mechanism. The door may also be closed by a float operativelvconnected with the valve controlling the supply of pressure fluid to the clutch-operating piston. An alarm switch or signal may be used to give warning of the mechanism being moved into the door-closing positions. Specification 29310/11 is referred to.

Title: Method and apparatus for high vacuum distillation
IPC: B01D3/26
Filed: 1948-06-16
Abstract: <PICT:0663754/III/1> <PICT:0663754/III/2> <PICT:0663754/III/3> <PICT:0663754/III/4> <PICT:0663754/III/5> Fractional distillation wherein pressures below 10 m.m. Hg. may be attained at all points in the system, is effected by contacting the vapour with a countercurrent stream of reflux-liquid in a series of stages wherein the flow of liquid leaving each stage is restricted so as to broaden the surface of the stream of liquid in each stage, and flowing the vapour from each stage into the next stage in a constricted stream directed against the broadened surface of liquid in said next stage so as to agitate the liquid without passage of the vapour-stream through the body of the liquid.  In Figs. 1 and 2, a still 16 is connected to the lower end of a column 14 inclined at 5 degrees to 10 degrees to the horizontal, and provided with a heat-insulating jacket 15.  The column is divided into stages by thimbles 19 sealed to the walls of the column; and an orifice 21 for the passage of vapour is formed in the lower wall of each thimble.  The upper end of the column is connected through condenser 24 to receiver 29 and a source of vacuum 35.  Part of the condensate is returned to the column via line 31 and valve 30.  The reflux flows down through the column via tubes 22, the flow being restricted and broadened out beneath each orifice 21 from which vapour impinges against the broadened surface. The volume of liquid in the column may be adjusted by changing the inclination of the column.  In an example, hexadecane was separated from octadecene by fractionating the mixture in a 12-stage column of the above type, inclined at 6 degrees to the horizontal, the diameter of the column being 6 cm. and that of the orifices, 3 cm.  The pressure in the still was 0.5 m.m. Hg. Another example describes the purification of diallyl phthalate by distillation in the above 12-stage column.  The vapour passing from the thimbles may be subdivided into a plurality of streams, e.g. by providing the vapour outlet from the thimbles with baffles 43, Fig. 6.  The column in this modification has saw-tooth ridges 44 over which the reflux-liquid cascades while flowing beneath the vapour orifices of the thimbles. In Fig. 11, the column is vertical, and is divided into stages by trays 51 connected by liquid overflow pipes 54, each tray being supplied by two pipes and being drained by two pipes, Fig. 13.  The feed is introduced through line 59 or line 76.  Vaporization is effected in reboiler 55 which is supplied with steam through valve 56 governed by temperature-controller 57.  The apparatus is evacuated via line 75, and, if necessary, a booster vacuum may be applied at one or more intermediate points.  The ascending vapour is blown down on to the surface of the liquid on each tray by risers 52 situated on the same sides of the trays as the two overflow pipes 54 draining liquid from the trays, Fig. 13.  Part of the bottoms are withdrawn through valve 64 governed by liquid level controller 65. The distillation of fatty acids is referred to.
