Abstract: 819,871. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. Jan. 4, 1956 [Jan. 7, 1955], No. 275/56. Class 87(2). Relates to moulding tubeless tyres and in particular to the elimination, from the cured tyre in the press, of water of condensation resulting from the curing medium in the tyre interior and comprises a press having separable mould halves 5, 6 ; upper and lower bead clamping member 25, 32 for clamping a tyre in the mould halves, and means to spread and hold the bead clamping members apart during opening movement of the mould halves after curing, the clamping members 32 having a central passage 52 for condensate to drain after the opening of the mould halves and jet means to blow residual condensate out of the tube through the passage. The condensate drains out over the top of the lower bead clamping member 32, which is dished at 36, through passages 52 in a sleeve 48 which carries the member and out through pipes 54, chambers 55 and conduits 57. The flange 33 of the lower bead clamping member also has openings 42 leading into passages 40 extending from bores 39 which communicate with a space in the top of the casing 12 on which the lower mould half is fitted, and some of the condensate drains through these channels and out through a pipe 16 and valve 17. As the press opens, the upward movement of the upper mould half is retarded to give time for the water to drain away. A timing device closes the valve 17 and opens a valve 20 in an air line 18, and air under pressure then passes up the pipe 16 and through the openings 42 and blows the residual condensate out of the lowermost part of the tyre and out through the passages 52 and conduits 57. The openings 42 branch fanwise from the passage 40 so that the jets are directed tangentially of the beads of the tyre and in opposite directions. The opening of the press is then completed and the cured tyre is stripped from the lower mould half. The flanges 28, 33 of the bead clamping members have concentric ribs 30, 34 to allow space for the tyre lining L to flow under the clamping pressure, small ridges then being formed where they are not objectionable. Specification 769,365 is referred to.

Abstract: 725,146. Cutting-machines. HALLDEN, K. W. Jan. 8, 1953, No. 653/53. Class 31 (1). [Also in Groups V and XXII] A device for cutting longitudinally moving paper and other sheet material into appropriate lengths includes a first rotated roller having a peripheral shear blade thereon and mounted in a fixed frame and a second rotated roller having a peripheral shear blade and mounted in a carrier movable to and from said first cutterroller by an eccentric rotated through a changespeed drive at a speed suitably selected relative to that of the cutter rollers so that the shear blades are close enough for cutting to take place only once in every n revolutions of the cutter rollers thus to cut the sheet into lengths of n units. Sheet strip 87 is fed between an upper cutter roller 24, fast on a driven shaft 27 journalled in a frame 14, and a lower cutter roller 34, fast on a shaft 33 journalled in a pair of parallel carrier plates 16 pivotally mounted about a shaft 18 secured to the frame 14. The lower cutter roller shaft 33 is driven from the upper cutter roller shaft 27 through a gear 28, fast on the shaft 27 and of lesser diameter than the cutter roller 24, gear 29 mounted on the frame 14, gear 31 loosely mounted on the shaft 18 and a gear 32, fast on the shaft 33 and of lesser diameter than the cutter roller 34, thus ensuring rotation of the cutter roller 34 for all positions of the carrier plates 16. Eccentrics 38 fast on a shaft 37, journalled in a fixed frame and driven through a change-speed drive, fit within blocks 39 slidable in the plates 16, so as to move the lower cutter roller 34 into shearing position once every appropriate number of revolutions of the cutters.

Title: Apparatus for use in a well
IPC: E21B34/00
Filed: 1973-01-04
Abstract: 1423293 Boring earth &c HYDRIL CO 4 Jan 1973 655/73 Heading E1F [Also in Division F2] A tool T adapted for connection in a drill string comprises a tubular body 10, a valve member 21 movable to open or close the bore, and a piston 30 connected to the means to urge it to the bore open condition when the pressure in the bore exceeds that in the interior of the body by a predetermined amount, the valve member 21 being moved away from its seat during this movement. The tool is connected in the drill string just above the bit to prevent blowouts through the bore of the string, the piston being urged upwardly by a spring 41 so that the ball member 21 closes the bore, a latch ring 52 being held in an upper position by a detent 55 and a detent 51 being in its upper position spaced from recesses 16i. The initial pressure of drilling fluid pumped down the string bore moves the member downwardly until the top of recesses 21c engage pins 24 carried by the piston so that the ball member 21 is not scored by the seat 25 during movement to the bore open position. The latch ring is not moved by fluid from the bore entering chambers 53, 54 since the effective upper and lower pressure surfaces of the ring are equal. Fluid from the bore in the chamber 54 is directly above the piston and fluid from the interior of the body enters a chamber 48 directly below the piston. When the pressure of fluid in the bore is sufficient to overcome the combined effects of the exterior fluid and the spring, the piston moves downwardly to pivot the member about pins 23 on the body to open the bore. Should pressure in the bore reduce or exterior pressure increase sufficiently the member rotates back to the bore closed position. The member is locked in the bore open position by lowering a locking plug (Fig. 6, not shown) into the tool bore, applying pressure to fluid in the bore and hence to the chamber 53 only to move the latch ring, detent 51, and piston downwardly so that the piston is locked to hold the member in bore open position, the locking plug then being removed. The lock may be released by means a release plug (Fig. 7, not shown). A stabbing sleeve (Fig. 8, not shown) may be screwed into the bore of the tool to move the piston and member to the bore open position, and the tool and sleeve may be screwed to the open top of a drill string. In the event of a blowout the sleeve is removed and the spring returns the piston and member to the bore closed position.

Abstract: 455,332. Automatic couplings for vehicles. LEOPOLD, K., 22, Moritzstrasse, Berlin. Jan. 8, 1936, No. 685. [Class 103 (v)] In an automatic coupling for railway &c. vehicles each coupler-head comprises a casing 3 having a coupling-bar 5 adapted to enter a recess in the opposed casing and to be engaged by spring-controlled catches or pawls 6, the casing also being provided centrally with a compartment through which pass pipes 20, 21, Fig. 3, for the flow of steam and for use in the vacuum or compressed air braking systems, and also conductors 23 of the lighting system. Each casing 3 is preferably flexibly supported by means of pivoted links 2 and tension springs 4 upon the shanks of buffers 1, and uncoupling is effected by admitting vacuum or compressed air from the pipe 21 to a cylinder 19 in which slides a piston 18 operatively connected to the catches 6 by a forked member 16, Fig. 1. Communication between the cylinders 19 and pipes 21 is established by pipes 22 and valves 8 which are actuated by links 33 and control rods 7 with handles 32 at the sides of the vehicles. The pipes 20, 21 are fitted with valves 27, 28 which are automatically opened when the casings 3 approach by means of levers 29 connected to plungers 30, which normally project beyond the faces of the casings, but which are forced inwardly by impact. In a modification, the valves are associated with fixed seatings and are displaced therefrom by being attached to sliding sleeves which are normally pressed outwardly from the casings by springs, but are forced inwardly when a coupling is being effected. In a similar manner the contacts of the electric conductors may be normally held in a retracted position by springs, but are forced outwardly when the vehicles approach by means of contact plungers and levers.

Title: Differential pressure control of sealing fluid for pumps, turbines, pump-turbines and the like
Inventor: CHATFIELD VICTOR G M
IPC: F03B11/00
Filed: 1966-01-07
Abstract: 1,130,091. Centrifugal pumps; hydraulic turbines. DOMINION ENGINEERING WORKS Ltd. Jan. 7, 1966, No.814/66. Headings F1C and F1T. A pump, turbine or pump-turbine is of the type in which fluid friction on the runner 14 is reduced by introducing air under pressure through pipes 24, 25 into spaces 20, 22 adjacent the runner shrouds 17, 18. After the air has displaced the water from the spaces 20, 22, excess air escapes through peripheral gaps 45, 46 and also tends to leak past seals 26, 28. This leakage is opposed in each case by a centrifugal pressure gradient in a rotating ring of water produced by each of two radially extending rings 27, 29 which extend from the runner 14 into stationary annular recesses. To keep the centrifugal pressure gradient within predetermined limits, it is sensed through lines 30, 31 or 42, 43 and used to control the pressure at which sealing water is supplied through pipe 41 or 44. For this purpose, the lines 30, 31 are connected through a pressure transmitter 33 to a pressure controller 34 whereby air supplied by a compressor 64 via an air receiver 61 and a line 67 is applied to control a valve 39 in the pipe 41. A similar arrangement is used for controlling a valve in the pipe 44. The control of the supply of air to the spaces 20, 22 is exemplified by the arrangement shown for the space 20, wherein air is supplied continuously to the space 20 via a throttle valve 63 and pipes 62, 24. If excessive loss of air from the space allows water to enter the space, the resultant centrifugal pressure differential sensed through lines 55, 30a is applied via a pressure transmitter 56 to a pressure controller 57, whereby air supplied through a line 71 is used to open a valve 59 to supply an additional short blast of air through pipe 24 to drive the water from the space 20.
