Title: Improvements in and relating to devices for adjusting the blades of a screw propeller
IPC: B63H3/08
Filed: 1944-03-27
Abstract: 594,124. Fluid-pressure servomotors. ROESCH, F. March 27, 1944, No. 5629. [Class 135] [Also in Group XXXIII] In a variable pitch propeller, an auxiliary motor is built into the propeller shaft 1-3, the piston 7 and cylinder 8 of the motor and the pitch-adjusting part 4 being constructed as a screw-thread gear, straight-line guiding means being provided between the pitchadjusting part and the piston, or between the piston and the cylinder. In the form shown in Fig. 1, the piston 7 is provided with a groove 6 to engage a longitudinal feather 5 on the part 4, and with projections to engage helical grooves 9 on the cylinder 8. The angle of inclination of the thread 9 is approximately equal to or smaller than the sum of the angle of friction of the thread and an angle corresponding to the static friction of the parts moving during the adjustment of the blades, so as to prevent unintentional. change in the setting of the blades. Pipes 18, 19 convey pressure medium to and from the cylinder 8 which is formed as a liner for the part 2 of the shaft in which it slides and is carried round by tongues 22 engaging gaps 23 in the part 3 of the shaft. In the form shown in Fig. 6, the motor casing 28 is bolted to the two parts 26, 33 of the propeller shaft and contains a liner 35 which is turned by means of tongues 76 and a second casing 29. The piston 36 is displaceable axially without turning by means of a longitudinal feather 37 and groove 38, and is threaded internally to engage a thread 42 on a shaft 41. One end of the shaft 41 is connected by a sliding coupling 44 to the pitch-adjusting part 46, whilst a steep pitch thread 60 on the other end engages a cross-head 61 connected by bolts 63 to a sleeve 65 rotatable with the propeller shaft and turnable in a stationary adjusting ring 66. The latter carries levers 68 connected to a pitch-adjusting rod 71 and to a valve 57 which controls the passage of pressure oil to and from the cylinder spaces 39, 40. Operation of the rod 71 moves the valve 57 in one direction, the pitch-adjusting shaft 46 is turned by the piston 36, and the cross-head 61 then moves in the same direction to restore the valve 57 to its original position, and the piston 36 is brought to rest. A chain wheel between the shaft flanges 31, 32 may drive a gear-wheel pump below the valve 57 for the supply of the pressure oil. In modifications, the control valve is arranged coaxially at one end of the servomotor and is adjusted by the adjustable pressure of an hydraulic or pneumatic transmission system which includes a hand wheel operated by a steersman. For showing the setting of the blades, an indicator may be geared to the hand wheel, or one or more pressure gauge indicators may be operated in accordance with the travel of the servomotor piston.

Title: Improvements in or relating to steam superheaters
IPC: F22G5/20
Filed: 1927-03-01
Abstract: 291,507. Hancock, P. H., and Twinn, H. C. March 1, 1927. Controlling superheat.-The temperature of the steam flowing from a superheater is controlled by a valve 5, Fig. 1, which allows the steam after passing through some of the elements 4 to pass in varying proportions either directly from the collector 2 to the' outlet 19 or through further heating elements 4<a> connected to the outlet through a header 3. Separate valves controlling the flow from the headers 2, 3 may be used in place of the mixing valve 5. The steam temperature may be controlled by means of flap valves 7.8, Fig. 3, fitted inside the headers. The upper and lower headers may be made in sections which may be connected by pipes fitted with the control valves. The valves are so constructed as to allow the passage of a small quantity of steam even when the valves are fully closed.

Filed: 1931-02-26
Abstract: 376,273. Sifting-apparatus. ROSS, W., Eversley House, Eversley Road, Surbiton, Surrey. Feb. 26, 1931, No. 6082. [Classes 59, 82 (ii), and 117.] In screening apparatus of the kind comprising spaced parallel members disposed transversely to the flow of material, the screening element consists of a pair of members one of which is a roller &c. which exerts an upward tractive effort on the material in the screening aperture for discharging the oversize constituent. Figs. 1 and 7 show one form of apparatus consisting of two rollers 2, 3 positively driven in the same direction and providing a screening space 3a to which the material is fed by a plate 6. The roller 3 is driven at a greater speed than the roller 2 so as to provide a resultant upward tractive force on the material lying in the screening aperture for the purpose of preventing the material jamming therein. Alternatively, the surface of the roller 3 may be made rougher than that of the roller 2, or a chain associated with the feeding device, Fig. 4 (not shown), may be provided to press the material against the roller 3. The clearing of the aperture may also be provided for by making the surface of the rollers of corrugated or irregular formation, or by vibrating them longitudinally. Preferably adjustment of the size of the screening aperture is provided for by mounting the bearings 23 of one of the rollers on threaded rods 24 passing freely through fixed blocks 25 and secured by nuts 26 and springs 28. In further modifications, the rollers may be driven in opposite directions so as to have a rising movement in the screening aperture, or the roller at the feed side of the aperture may be freely mounted or may be replaced by a plate 17, Fig. 5, fixed or oscillated or free to oscillate. The roller 3 may be associated with a rolling, reciprocating, or stationary element for crushing the oversize material, and means, such as spraying nozzles may be provided for washing the material with water or other liquid medium. According to the Provisional Specification, the screening apparatus may comprise a series of rollers rotating in the same direction at different speeds and disposed in a plane or on the surface of a cylinder. Associated with the rollers there may be provided a flexible belt which travels with the material.

[Class 52 (iii)] A typewriter &c. platform 26 is mounted in a desk on bell - cranks 18, and is shown in an intermediate position ; in its lowest position the arms 18 depend vertically from their pivots 16, and in its highest position the arms extend vertically upwards. The front being opened, a pull on a handle at the front edge of the platform 26 causes it to slide forwards on a frame 25, which is mounted on four arms 23 on the four bell-cranks 18, which are pivoted at 16 in side bars 15. These bell-cranks are connected in pairs by two transverse bars 17, which are connected by a central strip 20. The rear part of this strip is connected by a spring 21 to a transverse rod 19 also fitted between the side bars 15. As the platform 26 in its lowest position is pulled forward, an incline on it disengages a spring bolt from coinciding apertures in the bell-cranks 18 and the arms 23; a further pull forward causes the arms 18 to rotate on their pivots 16, gradually raising the platform to working position, in which position a rod 28 immediately beneath the platform 26 is moved by a handle at the front so that a finger at the other end engages with a fitting 31 attached to the side wall.
