摘要： The cartridge (10) has a bulkhead (14) carrying a housing (16) on which is mounted a hollow inlet member (20). A valve member (24) is accommodated in the housing and is attached to a valve operating rod (26) extending through the bulkhead and having a pilot control system mounted on the opposite side of the bulkhead from the housing. A valve seat (28) is supported on the inlet member, which defines with the housing an outlet (30), across which the valve member travels when moving towards and away from the valve seat. The pilot control system has an outlet tube passing through the bulkhead and communicating with the interior of the inlet member and having an outlet tube passing through the bulkhead and opening outside the housing and the inlet member. The cartridge has a slam-shut valve member (32) slidable in the lower end of the inlet member operated by a cable (42) and an actuator (46).

摘要： A percussive-action mole 10 is energized by compressed air supplied through hollow rods 36 in a string 12 connected to the mole. A hydraulic motor 18 rotates the string and mole. The mole head 30 has a slant face 32 and a transverse permanent magnet 34. After each new rod is added to the string, the air is stopped to halt the mole which continues to be rotated. The field fluctuations from the magnet are detected by a magnetometer 24 using its probe at three positions 50, 52, 54 determiend by a triangular frame 22 placed flat on the ground. Calculations using the three readings each representing the distance of the magnet from the respective position on the frame enable the position and depth of the magnet to be determined. After completion, the passage 38 can be reamed to larger diameter to receive a gas pipe or other service.

摘要： An encoder device encodes angular position in the form of electrical signals in dependence on the position of a rotatable member in relation to a series of discrete fixed contacts disposed about the axis of rotation of a rotatable member. A series of discrete fixed contacts 2a, 2b, carried by a panel 1, form a first group of contacts of a flexible switch structure which also has a second group of contacts 9 carried by a flexible sheet 7 and arranged such that each contact of the second group is located opposite to, but spaced from, one of the series forming the first group of contacts. An intermediate sheet 8 is sandwiched between the panel 1 and flexible sheet 7 and is apertured at 10 in the region of the contact sets 2a, 2b and 9. The rotatable member carries a switch actuator 14 which operates to close any of the oppositely disposed first and second contact sets, in dependence upon its angular position, the switch actuator being such that either one contact set is closed or two adjacent contact sets are closed for any angular position of the rotatable member. The output is derived from terminal areas 6 on the panel 1.

摘要： The burster has a body in two parts 10, 12 separable by pistons 20, 22, 24 in cylinders 14, 16, 18 in the part 12. The pistons have piston rods 32, 34, 36 secured to the part 10 by screws 54. The relative rectilinear movement of the parts 10, 12 is guided by the sliding engagement between the internal cylindrical surfaces 58, 60, 62 of the rings 44 and 46 and of the cylinder 18 and the external surfaces of the piston rods 32, 34, 36. Separating movement is effected by fluid fed into the three cylinders via a passage 88 and is limited by engagement between stop surfaces 66, 68 on the part 10 and stop surfaces on the part 12. Approach movement is effected by fluid fed into two cylinders 14, 16 via a passage 90 and is limited by engagement between the inner surface 64 of the part 10 and the rings 44, 46.

摘要： A service tee comprises a tubular T-piece 1 having a through-portion 2 with a flexible lower end 6 for connection to a gas or water main 70 by way of a hole in the wall of the main and a side branch portion 3 for connection to a service pipe. The end 6 of the through-portion 2 is adapted for initial insertion into the hole in the wall of the main 70 and then for subsequent radial outward expansion so that its surface sealingly engages with the edge of the hole. An expander 4 is provided for location within the end 6 of the through-portion 2 and is adapted in a first position to permit initial insertion of the end of the through-portion into the hole and on movement to a second position to cause expansion of the end 6 into engagement with the edge of the hole. A plug 5 is also provided, the plug 5 being engageable with the expander 4 and adapted to move the expander 4 from its first to its second position, the arrangement being that after expansion the plug 5 can be moved from a first position where the end 6 of the through-portion 2 is closed off from the side branch portion 3 to a second position where the side branch portion 3 and the end 6 of the through-portion 2 can communicate.
