Patent GB-2466385-A (GB)
Title: A pipe liner
Inventor: SANDERS SIMON
IPC: B29C63/36
Filed: 2009-12-21
Abstract: An evertable extended liner 5 comprising a liner 1 and an extender-tube 6 that are joined to form a continuous tubular entity. A pressurising fluid is introduced into the interior of the extended liner 5 causing it to evert and extend progressively, the uneverted part of the liner 1 passing through the interior of the extended liner 5, being drawn progressively in direction forwards towards the point of eversion. By this process the liner 1 and the extended liner 5 may be caused to evert into a pipe being lined where the liner 1 may subsequently be formed against the inner surface of the pipe by means of fluid pressure which may be applied directly or by a separate pressurisable tube, following which means for applying fluid pressure are removed and the extender-tube 6 is detached from the liner 1.

Inventor: LUBECK KARL HILDING OSSIAN
IPC: B60L7/12
Filed: 1919-04-22
Abstract: 125,988. Lubeck, K. H. O. April 20, 1918, [Convention date]. Brakes and retarding apparatus for winding and paying-out apparatus. - Electrically-driven lifts and cranes are, on braking, caused to drive an electric generator g which supplies current to run the motor m as a generator, the generator g being in parallel with the field winding of the motor. The generator g is connected by a variable transmission device with the motor shaft a. A friction drive is shown comprising a brake disk c with a plane outer face engaged by a wheel e movable on the generator shaft d by a lever f. The friction disk may be recessed at its centre, and the shaft d may have a universal joint i. The lever f is connected by spring v and rod l to a lever n carrying a pedal p. The lever n also has a rod u provided with a stop z which engages a lever s coupled at one end to a brake band r on the disk c and at the other end to a switch w in the main circuit. In operation, the pedal p moving from 1 to 2 carries the wheel e across the disk c from 9 to 10 where it has the greatest velocity. An arm k on the lever f then bears against an abutment x, and the stop z bears against the lever s. On further movement of the pedal p, the switch k is first opened and then the brake band r is applied to the disk c. The Specification as open to inspection under Sect. 91 (3) (a) states also that the method of first applying an electrical brake and then a mechanical brake may be used with other regenerative systems. This subject-matter does not appear in the Specification as accepted.

Abstract: 493,088. Blowpipe burners. LINDE AIR PRODUCTS CO. April 16, 1937, No. 10841. Convention date, May 19, 1936. [Class 75 (i)] In a blowpipe burner nozzle, the end 29 of an inner member B projects into the orifice 17 of an outer member A to provide an annular outlet 30 and the members are secured together by wedging longitudinal tapered ribs 34 on the inner member into a conical portion 18 of the bore of the outer member so as to maintain uniform the width of the outlet 30. As shown in Fig. 3, the end 29 is reduced to provide a gas chamber 32 and a boss 38 on an integral apertured flanged collar 36 of the member B engages in a deeper counterbore 20 in the member A to centralize the rear end of the member B and form a gas chamber 43. The nozzle is secured by a cap nut N to a head H, conical sealing surfaces 48, 49 being provided. In the modification shown in Fig. 8, the inner member B is of uniform internal diameter and is formed with an external annular groove 55 opposite a cylindrical portion 54, of the bore of the member A<1> to provide the chainber 32<1>. When used for cutting metals, a mixture of acetylene and oxygen may be supplied to the annular outlet 30 and the cutting oxygen through the central passage. For welding or flame hardening, the combustible mixture is supplied through the central passage and another gas, such as an inert gas, to the annular outlet.

Abstract: 802,704. Metal strip feeds. PRESS EQUIPMENT, Ltd. April 10, 1957 [April 10, 1956], No. 10884/56. Class 83 (4). [Also in Group XVI] Strip is fed to abut against a stop beyond the tools or dies of a machine which operate on the strip and as it reaches the stop the strip actuates a switch associated with or adjacent the stop to arrest or slow down the feed and to set the machine in motion to operate on the strip. Strip is fed from a reel 12 by feeding and straightening rolls 14 through a press 10 to abut the stop 24 which determines the length to be cut. The stop 24 consists of a housing 31 carrying the stop member 30 and mounted on a bell-crank lever 45 pivoted on a bracket 34 adjustably secured to a frame 21. A threaded rod engaging the housing 31 and a boss on the bell-crank lever 46 provides a fine adjustment of the stop. When the strip engages a flap 44, the switch 41 is actuated to slow or stop the feed and providing the press ram is at top-dead centre to pneumatically actuate a one-revolution clutch controlling the press. Just after the strip is sheared, a cam on the crank-shaft of the press actuates a valve to pass compressed air temporarily to cylinders 47, 53 which serve respectively to raise the stop-member 30 and to operate a pushbar which pushes the severed strip into a bin 26. The switch 41 releases and the feed rate is returned to normal. When the switch merely slows the feed rate the strip forms a hump 11 on the feed side of the press and this hump may be used to control an arm 83 to vary or stop the feed as an additional control during normal working or to stop the feed should the strip jam in the press. In a press used for blank punching, the stop engages the edge of an opening formed in the strip by a previous operation and is momentarily retracted during the feeding of the strip to clear the web between adjacent openings.

Pivoting-adjustments for the joints of windscreens of motor vehicles, particularly side screens, in which to lock the parts in adjusted positions a split sleeve is expanded by cones upon one member of the pivot into frictional holding engagement with an external tube on the other member. Each support for the main screen is fitted with brackets 2 to which the side screen 3 is pivoted by a vertical rod 4 passing through holes in the brackets and arranged to pass through a vertical tube 5 fixed at its ends to shoes 6 secured to the metal framing of the side screen. The lower end of the rod 4 has a head 7 and a square shank fitting in a square hole in the lower bracket so that the rod is prevented from turning, and its upper end is threaded and fitted with a nut 8. Around the rod fit two tubular locking-members 9 having conical ends engaging conical seatings 11 on a split sleeve 10, the bottom tubular locking-member resting on the lower shoe, and the upper one, which passes through a hole in the upper shoe, having projections engaging grooves in the upper bracket so that it cannot rotate. Upon tightening the nut 8, locking is effected between the rod, the brackets, and the outer tube. In a modification the lower locking member may be dispensed with, the split sleeve being arranged to engage a shoulder formed on the central rod.
