Title: Multi-way valve
IPC: F16K11/07
Filed: 1973-10-18
Abstract: 1387950 Valves ROBERT BOSCH GmbH 18 Oct 1973 [20 Oct 1972] 48698/73 Heading F2V A multiway valve having a slide 23 axially movable within housing 21 to control working fluid flow selectively from an inlet chamber 24 to one or other load connection 27, 28 and from the latter to drain chamber 26 includes ducts 33, 35 in housing 21 forming part of a control line 18 influencing a changeover valve (17, Fig. 1, not shown) for the direct return from source to drain of working fluid, and control grooves 48, 52 in slide 23 co-operating with ducts 33, 35 in respective angular positions of the slide to render the valve suitable for use with double or single acting loads. As shown slide 23 is in its neutral position and angularly disposed for double acting control, indicated by notches 57 on its upper surface, groove 48 in slide 23 permitting flow of control line fluid from duct 33 to duct 35 to thus maintain the change-over valve (17) open so that the working fluid flows directly from source to drain. The width of groove 48 is such that should slide 23 be moved leftwards or rightwards from neutral to direct working fluid from chamber 24 to load connections 27 or 28 respectively then control line flow between ducts 33, 35 is interrupted causing changeover valve (17) to close and prevent direct flow from source to drain. For single acting control, slide 23 is rotated through 180 degrees so that notch 58 is uppermost and control groove 52 cooperates with ducts 33, 35. Load connection 28 is blanked-off by a plug (59, Fig. 5, not shown). Groove 52 is of greater width than groove 48 such that control line flow between ducts 33, 35 is only interrupted when slide 23 is moved leftwards from neutral to direct working fluid to load connection 27. Slide 23 is provided with a pressure compensating groove 49 communicating via an axial groove 51 with control groove 48, the latter connecting via radial bore 53 with control groove 52. These grooves &c. in conjunction with bores 37 in housing 21 ensure that slide 23 is pressure balanced in all positions. Exhaust of fluid from load connection 28, during double acting operation, is via a branched chamber (29, Fig. 4, not shown) in housing 21, through diametrically opposite ports 47 in slide 23 to an axial bore 46, and thence through ports 54 into chamber 26. Accidental rotation of slide 23 between its single and double acting positions is prevented by the slide actuator. Two multiway valves may be combined in parallel to form a block (10, Fig. 1, not shown), one valve (13) being set for double acting control and the other (12) for single acting.

Title: Regulating arrangement for protecting a steam generator against air deficiencz
IPC: F23N1/02
Filed: 1974-11-11
Abstract: 1478626 Automatic control of steam generators SIEMENS AG 11 Nov 1974 [12 Nov 1973] 48750/74 Headings G3N and G3R A steam generator system includes a fuel and airflow regulating arrangement which adjusts set flow values so as to prevent a deficiency of combustion air during both steady and dynamic operational states of the system. As shown, a controller 1 produces a flow control value W in response to measured steam parameters. An amplifier 5 sums the control value W with a signla XL representing actual air-flow and an adjustable threshold signal #x L  to-form a compensating quantity XdL * which is fed to a minimum value selecting circuit 6 along with the time derivative w of the control value w formed in a circuit 4. The selected value, modified during startup by a time-varying signal from a desired value source 9, is supplied to a comparator which also receives the control value W as an input and feeds a desired value to fuel flow controller 2. An actual fuel flow signal XB is also supplied to the controller 2 which is connected to combustion plant 13. A desired value for the air-flow is similarly formed and fed to a controller 3 by combining the control value W with the actual value of the fuel flow XB and a threshold signal #x B  in an amplifier 7, comparing the resulting signal XdB * with the derivative signal w in a maximum selecting circuit 8, and subtracting the selected signal from the control value W. The regulator prevents an air deficiency when the load increases by first increasing the air-flow and then adjusting the fuel supply. Similarly, if the load falls, the fuel flow is decreased first and then the air-flow is throttled.
Patent GB-488398-A (GB)
IPC: G03C7/14
Abstract: 488,398. Colour photography. LASSUS ST. GENIES, A. H. J. DE. Aug. 19, 1937, No. 22784. Convention date, March 2. Addition to 487,685. [Class 98 (ii)] In a method of obtaining a colour photograph on a lenticular support, as claimed in the parent Specification, the illumination of each of the partial images in the course of the corresponding second exposure is associated with an operation of colouring the partial image and, by diffusion on a microscopic scale, the colouring of the neighbouring partial images, in a colour complementary to that which is finally to be obtained in the transparent parts of the partial image illuminated, the density of the colour being substantially proportional to the quantity of silver reduced in the course of each partial development. As shown, a blue object has been recorded in the left-hand part of the lenticular film F and a red object in the right-hand part. In the left-hand side the parts b of the emulsion, which correspond to the blue zone of the taking filter, contain, after development in a developer containing a silver halide solvent, the reduced silver and little silver halide, while the parts v and r, corresponding to the green and red zones of the taking filter, contain little or no reduced silver and much halide. On the right hand side the parts r contain the reduced silver. The film F is then partially exposed through the lenticulations so that only the parts b are illuminated, and the image is developed in a yellow colour developer such as pyrogallol or pyrocatechin. The yellow colour J is produced only in the parts b on the righthand side, and penetrates by diffusion into the parts v and r. The parts v are then illuminated and developed to purple in a colour developer containing thioindoxyl, the purple colour P being produced on both sides of the film and penetrates by diffusion into the parts v and r. The parts r are illuminated and developed to blue-green by a colour developer containing monomethyl-1 4-dinaphthol. The blue-green colour B is only produced on the left-hand side of the film F, and penetrates by diffusion into the parts v and b. The silver is dissolved out, and the mixture of purple and blue-green on the left-hand side gives blue, and the mixture of purple and yellow on the right-hand side gives red. In a modification yellow, purple and green dyes may be introduced into the emulsion one before each selective development and are destroyed by the nascent silver. After each partial development the dyes remaining in the gelatine are stabilized by turning or by rendering the dyes insoluble. The silver may be removed at the end of the treatment or after each partial development.
