Title: Improvements in and relating to power plants employing internal-combustion engine gas-generators
Inventor: MUNTZ FREDERICK ALAN IRVING
IPC: F02C6/02
Filed: 1961-01-25
Abstract: 935,268. Gas turbine plant. ALAN MUNTZ & CO. Ltd. Dec. 29, 1961 [Jan. 25, 1961], No. 2974/61. Class 110 (3). [Also in Group XXIX] A power plant employing one or more internalcombustion engine gas-generators of turbine or free piston type, supplying power to a prime mover, such as a turbine, has in addition an auxiliary radial inward flow turbine, having a variable nozzle area, which is driven by power gas from the gas-generators derived from a pipe coupling the gas-generators to the prime mover in which the pressure changes as the load on the prime mover changes. A battery of free piston gas-generators G1, G2, G3, G4 delivers gas to a common gas manifold 10. A pipe 11 feeds gas from the manifold 10 to a main turbine 12 driving a ship's propeller 13 through a reduction gear 14. Gas is also fed from the manifold 10 through a pipe 15 to the auxiliary turbine 16 driving an electrical generator 17. Gas from pipe 15 enters the turbine 16, Fig. 3, at an inlet 23 and is directed by nozzle blades 24 into a rotor 25. Each of the blades 24 is pivotally mounted upon the stator and is connected by a a lever 26 and a link 27 to a pivot pin 28 fixedto a control ring 29 which is rotatable through a small angle about the rotor axis relatively to the stator. Rotation of the ring 29 serves to increase the nozzle area, a blade rotation of 24 degrees requiring a rotation of 6 degrees of the ring 29. The control mechanism, Fig. 3, for rotating the ring 29 employs an oil relay which is controlled by two separate operating pressures, namely the control oil pressure derived from the speed governor 19 of the turbine 16 applied at 31 and the gas supply pressure at the inlet 23 which is applied through a pipe 32. The control oil pressure is fed by the pipe 31 into a cylinder 33 containing a piston 34 and a spring-loaded bellows 35. The pressure in the pipe 32 is applied to a cylinder 36 containing a piston 37 and a spring-loaded bellows 38. The pistons 34, 37 are connected by a link 39 to which is pivoted a lever 40 coupled to the ring 29 and to the rod of the main relay piston 42 operating in a cylinder 43 by a link 41. The slide valve control member 44 of the relay is pivoted to the lever 40. Oil is admitted to the relay at a port 45 and passes out at 46. Movement of the pistons 34, 37 thus rotates the ring 29. To reduce the sensitivity of the control mechanism at high gas pressures, a variable rate spring may be fitted in the gas pressure bellows 38. Alternatively, Fig. 4, the lower end of the lever 40 is coupled by a link 47 to a floating lever 48. The upper end of the lever 48 is coupled to the piston 34 and its lower end bears against a cam lever 49 having its lower end mounted on a fixed pivot 50 and its upper end coupled to the piston 37. Hence as the gas supply pressure increases the lever ratio alters and the sensitivity is reduced.

The strip 2 may be of metal (e.g. aluminium): The locating strip 1 may be cut from a roll with the coated faces protected by "peel-off" layers of oiled paper: the adhesive may be based on uncured rubber embedded in silk. In the form of strip illustrated in Fig. 2 (not shown) the metal strip (2) is of laminated construction comprising two metal layers (5) interconnected by resilient material 6 which may comprise an additional layer of adhesive. Fig. 3 (not shown) illustrates a strip (1) secured to an hydraulic piston, and Fig. 4 (not shown) illustrates a strip (1) secured in a recess (11) of a disc brake yoke (8) which recess (11) also receives at least partially an indirectly actuated friction pad assembly. In Fig. 5 (not shown) the support againcomprises an hydraulic piston (7) and the strip (1) is shown received in a recess (15) in a backing plate (13) of a friction pad assembly (12): The recess may be circular (Fig. 6, not shown) or in the form of a transverse slot (Fig. 7, not shown).  In another construction (Fig. 8, not shown) strips (1) are applied diagonally to a planar face of the backing plate (13) so that the piston (7) acts on the pad assembly only over four angularly spaced contact areas (16). In the construction of Fig. 9 (not shown) a strip (1) is applied to a planar face of the backing plate (13) for engagement by a yoke. Figs. 10-12 illustrate a disc brake having friction pad assemblies 18 operable by opposed pistons 19. Between each piston 19 and the backing plate 22 of the respective pad assembly 18 is interposed a shim 23 having the form of the strip of Fig. 1 or Fig. 2. A part 24 of each shim 23 is cut-out to restrict the area of contact of the pistons 19 therewith. The shims 23 restrict and damp any relative movement, radial or circumferential between the pistons 19 and the pad assemblies 18.

Title: Improvements in or relating to the twisting of textile yarns
Inventor: SCRAGG FREDERICK
IPC: D02G1/08
Filed: 1958-02-05
Abstract: 857,872. Crimping yarns, twist tubes &c., yarn guides. SCRAGG & SONS Ltd., E. Nov. 27, 1958 [Feb. 5, 1958], No. 3705/58. Classes 120(2) and 120(3). Apparatus for false-twisting yarn e.g. in a crimping process, comprises at least one surface conforming to a figure of revolution and having a high coefficient of friction relative to the yarn, means for producing relative movement between the yarn and the surface so as to rotate the yarn, and a resilient constraining device acting on the yarn in the vicinity of the surface to maintain not less than a predetermined pressure therebetween. As shown in Fig. 1, yarn 13 fed by roll 14 is passed through rotating cylindrical friction members 11, 12 (so that it is engaged and twisted by portions 11a, 12a) by a roller 16, carried on a spring 19, and rollers 15, 17. In the apparatus of Fig. 4, yarn 13, travelling upwardly through members 21, 22, is traversed circumferentially around engaging surfaces 21a, 22a by a constraining guide eye 26 on a resilient wire 29 carried on a wharve 30 rotated by a belt 31. In a similar apparatus, Figs. 5 and 6, comprising the stationary bushes 21, 22, a rigidly mounted guide 36 on rotating wharve 37 co-operates with a double, resilient, lagging member comprising eyes 38, 39, carried on wire portions 40, 41, mounted on a support 42 which is freely rotatable around the bush 22 on a bearing ring 43 and is dragged by tension in the yarn. Another embodiment, Figs. 7 and 8 (not shown) corresponds to the apparatus described in Specification 857,875. Specification 464,981 also is referred to.

Title: Device for copying sheet-like originals
IPC: B65H9/10
Filed: 1974-01-28
Abstract: 1401416 Feeding sheets OCE-VAN DER GRINTEN NV 28 Jan 1974 [29 Jan 1973] 03852/74 Heading B8R [Also in Division G2] As the original is fed towards the exposure station in a photo-copying machine, any axial or rotational movement away from the correct position is detected and a restoring movement applied. The machine (Fig. 1, not shown) is of the type in which the original and copy sheets are passed in contact around a printing cylinder (30), with an internal light source (31). After leaving the exposure station the sheets are separated, and the copy sheet passed to a developing station. The original may be passed out of the machine, or recycled for further copying. Upstream of the exposure station it passes between a pair of rollers 10, 11, and one edge bears against a lateral guide 2. The lower roller 11 is mounted on a shaft 81 supported by plates 84, 85. On shaft 81 are mounted sliding bushes 86, 87 which support a cylindrical tube 88, the arrangement being such that tube 88 can move axially along shaft 81. A pin 89, fixed in shaft 81, extends through openings 90, 91 in tube 88, so that rotation of the shaft is transmitted to the tube. On the outside of tube 88 are a number of rubber rings 92, on which the upper roller 10 rests. At one end of bush 86 is a circumferential groove 93, in which engages one end 94 of a lever 85. The other end of the lever is attached at 102 to the core of a solenoid 97, and another point 101 near the end is attached to the core of another solenoid 99. Both cores are spring-loaded, as shown. Thus when only solenoid 97 is energized, spring 100 pulls the lever 95 clockwise, so that the rollers are pushed to the right. When only solenoid 99 is energized, spring 98 pulls the lever anticlockwise, so that the rollers are pushed to the left. As seen in Fig. 2, three detecting elements 70, 71, 72 are positioned near the rollers. Element 70 is just before the nip of the rollers, and elements 71, 72 on either side of the desired position of the left hand edge of the original sheet. As soon as element 70 detects the leading edge of the approaching sheet, the drive to rollers 10, 11 is temporarily arrested. The sheet is still pushed forward by preceding pairs of rollers, so that if the sheet has been slightly skewed out of position, its leading edge locates in the nip between rollers 10, 11 and it straightens itself again. After a predetermined time the drive to rollers 10, 11 starts again. When the sheet is correctly located, element 72 is actuated but element 71 is not. If both elements are actuated, the sheet is too far to the left, and if neither element is actuated it is too far to the right. The elements are in circuit with the solenoids 97, 99, and if the sheet is too far to the left or the right the appropriate solenoid is energized to apply a correcting movement to the rollers.
