Title: Improvements in or relating to friction clutches
IPC: F16D45/00
Filed: 1958-11-06
Abstract: 864,521. Friction clutches ratchet clutches; slip couplings gearing for stopping and starting machinery. FRANCAISE DU FERODO S.A. Nov. 6, 1958 [Nov. 9, 1957], No. 35740/58. Class 80 (2). The driven disc 24 of a clutch for a motor car &c. is connected to an output shaft 11 through torsional vibration damping friction rings 71 in parallel with the usual helical springs 33, arranged tangentially in holes 32 in the disc and in holes 34 in a slip coupling disc 36 mounted upon a ratchet clutch 45 carried by a hub 26 keyed to the output shaft, the ratchet clutch overrunning when the output shaft 11 tends to drive an engine shaft 10, as during engine braking of the motor car, braking torque then being transmitted from the shaft 11 through a slipping friction coupling 46 in parallel with the ratchet clutch 45 to the friction disc 24. The slip coupling comprises a frusto-conical friction lining 47' carried in a disc 48 splined on the hub 26 and biased by a spring 50 into engagement with a corresponding frusto-conical periphery 46, interrupted by slots 60, on the disc 36. In a modification, Fig. 5 (not shown), the frustoconical lining is mounted upon the disc 36 and engages a co-operating peripheral surface upon the disc 48. As shown, the engine shaft 10 of the car is fast with a casing 21 which can be connected by the disc 22 of an auxiliary clutch to a carrier 19 supporting pivoted masses 18, which when rotated fly radial outwards to engage a a cam surface upon a thrust plate 17 connected by a bearing 16 to an engaging plate 15 transmitting clutch-engaging force through springs 14 to a pressure plate 13 fast for rotation with the engine flywheel 12. On energization of a stationary solenoid 23, during a ratio shift, the auxiliary clutch disc 22 is withdrawn from engagement with the rotating clutch casing 21 and is brought to rest, together with the carrier 19, so that the masses 18 move radially inwards and disengage the main clutch 12, 13, 32. The driven clutch disc 24 carries a ratchet gear 52 having teeth 53 engaged, when the engine shaft 10 and flywheel 12 are at rest, by pivoted centrifugal pawls 54, so that the motor car engine can be started by towing. As soon as the engine starts, the pawls 54 are biased by centrifugal force to a position where they are clear of the ratchet teeth 53 on the gear 52, and guards 54a move outwards to cover the teeth. Shocks caused by engagement of the centrifugal pawls 54 with the teeth 53 when the motor car engine stops suddenly are thereby avoided. The ratchet clutch 45 comprises spring-biased clutch rollers 45a alternating with bearing rollers 45b.

Title: A Head for Filling Containers
IPC: B65B31/00
Filed: 1968-07-29
Abstract: 1,174,080. Head for filling containers; dispensing measured quantities of liquid. COSTER TECHNOLOGIE SPECIALI S.p.A. 29 July, 1968 [29 July, 1967], No. 36010/68. Headings B8N and B8T. A head for filling containers, such as aerosol containers, with a predetermined amount of fluid, particularly a propellant, comprises a cylinder 1, a hollow chamber 3 in communication with the cylinder, conduit 10, a body member including parts 13, 14, 15, 16 movable with respect to the chamber, and a passage extending through the body member and terminating in a mouth which is intended to co-operate with the container. When the head is at a rest condition pressurized fluid is admitted to the chamber 3 via conduit 10 and further to the cylinder 1 via hole 4. The fluid cannot flow out of the head because radial holes H in body member 25 are located below the central fluid passage. For filling a container the head is lowered, such as by a cam, whereupon a compression of spring 30 allows the upper end of sleeve 29 to bear against member 14 and the radial holes H to be positioned above sealing element 28. As the lowering of the head still continues, hole 20 in cup 18 aligns hole 4 so that the passage is shut-off from the pressurized fluid source via conduit 10 but brought into communication with fluid in cylinder 1. A piston 5, Fig. 1 (not shown), movable in cylinder 1, forces fluid from the cylinder into the container, the piston being activated by pressurized fluid acting on its upper face. When the head is lifted the elements revert to their rest condition.

Filed: 1952-12-24
Abstract: 760,389. Waveguide accessories. DECCA RECORD CO., Ltd. Dec. 24, 1953 [Dec. 24, 1952], No. 36067/55. Divided out of 760,317. Class 40 (8). A microwave transmission limiter comprises a waveguide 118 having a short-circuited stub 119 containing a piece 121 of ceramic dielectric material of the high dielectric constant type such as barium titanate. Materials of this type have a dielectric constant dependent upon the magnitude of an applied electric field. Hence the position and size of the element 121 may be chosen so that changes in the dielectric constant due to changes in amplitude of the incident microwave field vary the effective position of the short-circuit to limit the power passing along the waveguide 118 past the stub. The effective position of the short-circuit may be adjusted by applying a control potential to the element 121 in the manner described in Specification 760,317. The element may be matched to the stub guide as described in the above mentioned Specification. Specifications 760,386, 760,387 and 760,388, [Group XL (c)], also are referred to.

Filed: 1971-10-02
Abstract: 1372236 Processing 3D data CONTINENTAL OIL CO 2 Oct 1971 [5 Oct 1970] 36222/71 Heading G4A A multiprogrammed data processing system in conjunction with an output plotter is arranged to process three-dimensional data for output in the form of a contour map. The processing system includes a central processor with internal core storage, external disc and tape backing stores, and I/O units such as a punched card reader. The programs used include an executive program which is initially loaded into the core store and which selects one of a number of operational programs stored in the backing store, causes the selected program to overwrite the executive in the core, the executive having been copied into the backing store. When the selected program has been executed it is overwritten by the executive which is brought back into the core storage to select the next operational program. Two operational programs may be linked so that the first, A, calls the second, B, into the core. When B finishes a return is made to A and subsequently to the executive. The input data may relate to geophysical parameters and may be in one of two basic forms, viz. regular and irregular. Regular data consists of specified Z co-ordinates each corresponding to a point on a defined two dimensional X, Y grid. Irregular data is processed by an appropriate "gridding" program to convert the data to regular data. A program is provided to form contours from the data. The contours are plotted by the output plotter and may be displayed on a C.R.T.

Abstract: 935,363. Roller mills. E. CAVALIERI. Nov. 2, 1959, No. 37079/59. Class 59. [Also in Groups XXIX and XXXIV] In a refining machine, particularly for chocolate and like substances which comprises a series of refining rollers adjustable with respect to a fixed refining roller, each of the adjustable rollers is movable towards an adjacent roller by hydraulic means and away from an adjacent roller by mechanical means, each of the hydraulic means having coupled thereto a hand-operated device for controlling the supply of pressure fluid thereto and the arrangement being such that when a roller is moved towards an adjacent roller, the remaining rollers are moved automatically to maintain unaltered the pressures existing between the remaining rollers. The machine shown comprises refining rollers C 1  to C 4  having journals P 1  to p 4  rotatable in supports S 1  to S -4  of which the support S 1  is fixed to a frame 1. Pressure chambers a 2  to a 4  are respectively connected to the supports S 2  to S 4  and pistons b 1  to b 3  are respectively connected to the supports S 1  to S 3 . Each pressure chamber, e.g. a 3 , has coupled thereto by means of a conduit, e.g. 7C 3 , a cylinder, e.g. 3C 3 , having a pressure gauge 4 and a piston 5 micrometrically adjustable by means of a hand wheel 6. If, for example, it is desired to reduce the distance between the rollers C  2  and C 1 , hydraulic liquid is passed through conduit 7C 2  into chamber a2 and since piston b 1  is fixed, chamber a 2  is lowered together with roller C 2 . It also follows that the whole assembly C 2  to C 4  will be lowered since the chambers a 3  and a 4  are lowered with supports S 3  and S 4  by an amount equal to the displacement of the chamber a 2 . Movement of a roller away from an adjacent roller is effected by means of return springs 8. In a modification, the chambers a 2  to a 4  are connected to the corresponding supports S 2  to S 4  by connecting elements having in their upper parts windows for the passage of brackets connected respectively to the supports S 1  to S 3 . Each bracket has a corresponding piston b 1  to b 3  respectively in the lower centre part. Return springs are mounted between adjacent supports. Reference has been directed by the Comptroller to Specifications 677,729 and 744,478.
