Abstract: 1,130,399. Centrifugal separators. PENNSALT CHEMICALS CORP. 14 March, 1967 [17 March, 1966], No. 11833/67. Heading B2P. In a centrifuge for separating a viscous liquid component from a liquid mixture, wherein the component accumulates in an annular pocket 32 on top of the centrifuge bowl 12 and is discharged therefrom by means of a stationary skimmer 38-52, accidental discharge of the viscous component direct from the pocket 32 to the outside of the bowl via the annular passage between the bowl drive shaft 14 and the skimmer 38-52, is prevented by means of an axially extending baffle 74 on the skimmer which projects into an annular groove 72 in the bowl or as shown, in a member 66 associated therewith, and which deflects any of the viscous component, which would otherwise be discharged directly, downwardly into the groove 72 and against adjacent radial vanes 68 which throw the viscous component back into the pocket 32. The member 66 is screwed to a vaned centre tube 16a rotating bodily with the bowl 12 and carrying frustoconical discs 16 and serves also to deflect diluent, e.g. hot water, supplied through a nozzle 64-64a, into the pocket 32 to facilitate discharge of the viscous component. As shown, the viscous component is constituted by the light liquid component while the separated heavy liquid component passes from the interior of the bowl into a pocket 26 from which it is discharged by means of a skimmer 36. The skimmers are provided with annular ribs 60, 62, 60<SP>1</SP>, 62<SP>1</SP> which serve to deflect back into the respective pockets any liquid flowing inwardly past the skimmers. Rotation of the liquid in the pockets 26, 32 is insured by vanes 28, 30a, 34. A shield 63 on the underside of skimmer 36 serves to control turbulence. A number of concentric baffle-groove arrangements similar to 74-72, may be provided. The viscous component may be constituted by the heavy liquid component in which case the arrangement 74-72 would be applied to the pocket 26.

Patent GB-123519-A (GB)
Title: Improvements relating to Fluid Pressure Braking Apparatus.
Inventor: WALTER VICTOR TURNER
IPC: B60T13/66
Filed: 1918-07-25
Abstract: 123,519. Turner, W. V. Feb. 20, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Fluid-pressure.-To permit rapid and more uniform charging of railway train brakes, certain of the vehicles distributed throughout the train are fitted with air compressor equipment adapted to be connected to the train-pipe by valve mechanism electrically controlled from the locomotive or other point. Electrically controlled equalizing discharge valve mechanism for effecting gradual application of the brakes may be combined with the charging valve mechanism and an electrically controlled emergency vent valve may also be added. The equipment includes a compressor 1. main reservoir 2, and a valve mechanism 3 comprising a slide valve 17, the chamber 14 of which is in communication with the pipe 4 and feed valve 5 with the reservoir 2. The slide-valve 17 when moved to the left by energizing the valve magnet 12 connects the chamber 14 with the train-pipe 8 and also with the upper chamber 19 and reservoir 22 of an equalizing discharge valve 18, the lower chamber of which is connected to the train-pipe 8 by passage 23 and has an exhaust port 25. The chamber 19 is adapted to be vented to apply the brakes by the passage 21 controlled by the magnet valve 26. When the valve magnet 12 is deenergized, the valve 11 connects the passages 10, 38 leading respectively from the piston and valve chambers 9, 14 of the slide valve 17 which therefore assumes the lap position shown under the influence of the spring 39. In charging the system, the valve magnet 12 is energized whereby the piston chamber 9 of the slide valve 17 is vented through the passage 10 and port 40 and the slide valve therefore moves to the left and uncovers the passage 20 allowing air to flow from the chamber 14 to the equalizing discharge valve chamber 19 and by passage 21 to the reservoir 22. The slide valve cavity 42 connects the passage 24 and 41 also so that air can feed into the train-pipe 8 from the chamber 19. To effect a service application of the brakes the valve magnet 12 is deenergized to return the slide valve 17 to lap position and the valve magnet 26 is energized to open the chamber 19 to exhaust by passage 21 and port 28, whereby the equalizing valve piston 18 is actuated in the usual way to vent the trainpipe by passage 23 and port 25. To release the brakes, the magnet 26 is de-energized and the magnet 12 energized to recharge the train-pipe and effect the return of the triple valves throughout the train. An emergency application of the brakes can be obtained by energizing the valve 7 adapted directly to vent the piston chamber 30 of the triple valves. A passage 46 with a check valve 47 enables the equalizing reservoir 22 to be charged from the train-pipe in the event of failure of the main reservoir pressure on a car and permits the apparatus to operate in making a service application of the brakes.
