Title: Control system for a power producing unit
IPC: F01K13/02
Filed: 1974-09-03
Abstract: 1486569 Controlling boilers BABCOCK & WILCOX CO 3 Sept 1974 38463/74 Heading F4A [Also in Division G3] A power generating system comprising two boilers and a single turbine has each boiler controlled by a demand signal produced by providing a total desired output signal and a ratio controller responsive to this total signal to generate the individual boiler demand signals. In the arrangement shown in Fig. 1 the boilers are shown as A and B and include a furnace 20, primary and secondary superheaters 21, 12 and an interstage reheater 13. The turbine 8 has a high pressure stage 9 and a low pressure stage 10 and drives a generator 11. The steam after passing through the low pressure stage is condensed and pumped through low pressure heater 16, de-aerating heater 17 to the feed pumps 18 for the respective boilers. In the control system shown in Fig. 3, a demand signal is generated corresponding to the desired energy output and this is converted in master controller 30 into a total boiler demand signal. The ratio control 32 provides a demand signal for boilers A and B which are used in the respective feed water, firing rate and reheat flow controls. In general  there are limits on the various parameters which are used in the boiler operation and by a "least wins" arrangement, the actual individual boiler demand signal is limited and the output of the other boiler will be increased to compensate. If the operation of the limiting factors on both boilers means that the total demand cannot be met then after a time delay the demand signal in system 28 is reduced to meet the actual system operation condition. The temperature of the steam at the turbine throttle valve may be used to modify the response of the individual boilers to their own demand signal. The monitoring and control of the feedwater supply is described and also forms the subject of Specification 1,486,570. Details of the firing rate and reheat controls are given.

Title: Improvements in or relating to a Method of Winding Wire helically on to a Tube
IPC: B29D23/00
Filed: 1967-08-23
Abstract: 1,157,034. Coiling helices. CONTINENTAL GUMMI-WERKE A.G. 23 Aug., 1967 [30 Aug., 1966], No. 38833/67. Heading B3E. [Also in Division F2] A method of covering a mandrel-supported tube with helically wound wire comprises securing a number of wires to one end of the mandrel, uniformly distributing the wires over the periphery of the tube and cutting them to a length longer than the tube, extending the wires parallel to the tube, passing them through axially displaceable wire guiding means surrounding the tube, uniformly tensioning the wires and securing the cut ends so that they are yieldable in the axial direction on a predetermined tension being exceeded, whilst being freely rotatable on their own axes and effecting the helical winding of the tube by bringing the wires into contact with the rotating tube in response to the longitudinal displacement of said wire guiding means. The flexible rubber tube 1 is drawn on to a mandrel 2 which is gripped at one end by a headstock chuck 3 and at the other end by a chuck in a tailstock 4. Both chucks are driven at the same speed. A number of wires 17 which have been previously cut to length are equally spaced around the mandrel and are held in a clamp 15. The clamp consists of a sleeve on the mandrel which has a number of axial bores corresponding to the number of wires. Each wire is passed through one of the bores and the wires are clamped against the mandrel by a tapered sleeve and a nut. The wires pass through holes in a guide plate 8 mounted on a carriage 9. A motor 11 drives the carriage along the bed and a hand wheel 12 is provided for making adjustments. The free ends of the wires are taken back to a clamping ring 13 in which are holes corresponding to the holes in the guide ring 8. Each hole contains a bush in which is a spring finger which resiliently grips the wire. To prevent the wires sagging between the guide ring 8 and the clamping ring 13 a support ring 24 is provided which is generally similar to the clamping ring 13 but has holes through which the wires pass freely. Both the clamping ring and the support ring are able to pass over the tailstock 4. The carriage on which the clamping ring is mounted is movable on the bed against an adjustable friction brake. To prevent the tube and mandrel sagging supports 10 are positioned along the bed and are lowered as the guide ring 8 passes.

Filed: 1972-08-21
Abstract: 1401311 Camera mechanism EASTMAN KODAK CO 21 Aug 1972 [21 Aug 1971] 38932/72 Heading G2A A camera for use with film having one metering perforation per frame has film transport and shutter cocking mechanism including a sensing member for engaging the metering perforation, and is characterised in that after an exposure the sensing member is moved out of the perforation by shutter-actuated means. The mechanism is similar to that described and shown in Specification 1395992 in which a spring-loaded slider 6 is moved in direction A twice in succession, the first movement cocking the shutter and the second actuating the film transport. The present arrangement includes an exposure aperture 18 and associated sliding shutter elements 19 and 20. Fig.2 shows the mechanism after shutter cocking and film transport, ready for an exposure. Shutter element 19, under the action of a spring 16, closes the exposure aperture, and shutter element 20 is held in the position shown by a part 20b which hooks on to a detent 21. On pressing the shutter release, lever 7 is pivoted clockwise, releasing the tensioned drive lever 1 which also pivots clockwise. Arm 1a of lever 1 strikes a lug 19a on shutter element 19, driving it to the left and so uncovering aperture 18. After a period of time controlled by an electronic timing device a magnet 22 is energized. This attracts the detent 21, thus releasing shutter element 20, which is pulled to the left by spring 17, so closing aperture 18 and terminating the exposure. During this movement element 20 pivots pawl 23 to disengage from control lever 8, which hence pivots clockwise under spring 24 to engage the sensing member 4. Member 4 hence pivots anti-clockwise on its mounting pin 28 and its sensing finger 4a is drawn out of the film perforation 5a. By delaying this withdrawal until after the exposure has been completed, no undesired film movement can take place after film transport or during the exposure.
