Patent GB-593972-A (GB)
Title: Control of change-speed mechanism
IPC: F16H61/02
Filed: 1945-06-21
Abstract: 593,972. Variable-speed gearing. LEA-FRANCIS CARS, Ltd., (formerly LEAFRANCIS ENGINEERING (1937), Ltd.), and RIDLEY, J. C. June 21, 1945, No. 15827. [Class 80(ii)] A control valve unit for a hydraulically-operated speedchanging mechanism of the kind described in Specification 408,059, in which the gear is first put into neutral by a hydraulic neutraliser and the selected gear is then engaged by a hydraulic actuator, comprises a rectangular block in which six parallel plunger valves 12 (one only being shown) are arranged, these valves corresponding to speeds 1 to 4, neutral and reverse. The plunger bores all intersect a passage 15 which is connected at one end 16 to receive a pressure-fluid supply and at the other end 18 to an exhaust conduit. A cross-passage 29 near the inlet 16 leads from the passage 15 to act upon the head 28, Fig. 2, of a plunger 21 working in a bore 36, which has a connection at 20 to the hydraulic neutraliser (not shown). With all the selector valve plungers 12 in the inoperative position shown a waisted portion 17 on each plunger allows the free passage of the hydraulic fluid to exhaust so that no pressure is built up and the plunger 21 is maintained by a spring 22 in the left-hand position shown. If one of these plungers is depressed, however, the portion 32 of the plunger blocks the passage 15 and creates a build-up of pressure which acts through passage 29 on the head 28 of plunger 21 which moves to the right. On initial movement the plunger 21 covers up a breather and feed port 34 in the bore 36 and forces hydraulic fluid out through connection 20 to operate the neutralising device. On further movement a waisted portion 24 uncovers the port 34 to release the pressure in the neutraliser, through axial and cross bores 26 in the plunger 21, which thereupon returns to its normal inoperative position. On final movement onto a stop 27 the plunger 21 uncovers a passage 41 to the pressure fluid from passage 29 from where it passes to a passage 42 parallel to passage 15. This passage has cross-ports 43 communicating with all the plunger bores, except the neutral one, and controlled by the portions 32 of the plungers so that whichever one is depressed uncovers its port 43 to allow the pressure fluid to pass to an opposite port 45, Fig. 3, leading to the selected actuator (not shown) to engage the desired speed. When the operation is completed the operated plunger is released and all the various parts of the control valve unit return to their original positions, the ports 45 to the actuators being opened to exhaust through passages 48 into an exhaust passage 49. The pressure build-up when one of the plungers is depressed may also be utilised to actuate a vehicle clutch by connecting a clutch actuator to the supply end of passage 15, and a tail end coupling of the type, for example, described in Specification 593,973 may also be provided. This coupling may be also hydraulically actuated in parallel with the main clutch.

Filed: 1948-06-12
Abstract: A de-aerator for boiler-feed water comprises two or more compartments through which the feed water is sprayed in countercurrent to a flow of steam, the compartments communicating with one another so that water in the base of succeeding compartments can flow into the first compartment and a pump being provided <PICT:0638198/III/1> <PICT:0638198/III/2> to withdraw water from the first compartment and discharge it as spray into the succeeding compartments.  The de-aerator (Fig. 1) comprises a shell 1 divided by partitions 2 into two or more compartments 3, 4 provided with spray nozzles 5, 51. Feed water, under the control of a float valve 6, is delivered to a chamber 7 which feeds nozzles 5 and water from the well of chamber 3 is withdrawn by pump 10 and delivered to chamber 12 feeding the nozzles 51 in compartment 4.  De-aerated water is withdrawn from the well 13 of chamber 4 by extraction pump 14 and discharged to boiler feed pump 15.  Pump 10 is operated at a constant capacity which is higher than that of pump 14 so that more water is circulated than is withdrawn and a difference in water-level is obtained in compartments 3, 4, the water in compartment 4 flowing over a weir into compartment 3.  Steam enters the de-aerator at S and is directed by partitions 2 in countercurrent to the spray of water from nozzles 5, 51. Non-condensable gas is withdrawn at 8, 16, additional spray nozzles 9, 17 being provided at these points to serve as devaporizers. Perforated spraying trays 18 are provided in each compartment.  In a modification (Fig. 2), feed water is discharged to compartment 3 under the control of a float valve 19 influenced by the water-level in compartment 4. Means are also provided to short-circuit the de-aerator and draw water direct from the feed tank 20 in case of emergency.  In further modifications, the de-aerated water is collected in a storage tank to obviate the use of float-gear; the compartments of the de-aereator are superimposed upon one another in a vertical cylindrical shell.
