Abstract: A spring-containing device comprises a housing including a removable end plate (2). A plurality of screw-threaded tie rods (7) have nuts (28) holding the end plate (2) in assembly in the housing. A safety plate (14) is disposed within the housing at a fixed spacing from the end plate (2) but short of a movable spring-retaining plate (8) at its closes approach to the end plate (2). The safety plate (14) is fast on a shaft (15) rotatable in the end plate (2) and adapted (at 16) to be turned from outside. The safety plate (14) has keyhole-shaped openings through which the respective tie rods (7) extend and the tie rod (7) have safety collars (18) which can only pass through the keyhole-shaped openings when the safety plate (14) is in a certain angular position.

Abstract: The arrangement comprises a stop bar (1) formed from a cylindrical rod having a lengthwise slot therein. The stop bar (1) is secured to a fixed support within an actuator casing (7). A stop plate (15) is slidably secured in the slot and presents upper and lower stop edge portions (16, 17) for engagement with spaced limbs (23) of arm means for converting linear motion into angular motion. The position of the stop edge portions (16, 17) relative to the stop bar (1) is adjustable by means of replaceable shims (21) in the slot.

Abstract: A ball valve is provided especially for use between adjacent sections of a pipe line conducting an inflammable fluid and comprises a valve housing, a valve ball (2) in the housing and having a through passage, a trunnion in the housing projecting into a first socket in the ball, and a control shaft projecting into and drivingly engaging a second socket in the ball diametrally opposed to the first socket. A pair of annular valve seat members (4) spaced axially of the pipe line carry sealing rings (8), spring means (9) urging the seat members towards the ball. Each seat member at its end adjacent the spring means has a frusto-conical portion (11) which tapers from a shoulder (12) on the seat member towards the end face (4A) of the latter. A graphite ring (13) is fitted between the frusto-conical portion and the adjacent peripheral wall of the housing and a first spacer ring (14) is located between the graphite ring and the shoulder. Furthermore, an annular pressure plate (15) is located between the end face of the seal member and the spring means and is abutted by the latter and has an annular lip (15A) abutting the graphite ring. Additionally, a second spacer ring (16) is provided between the end face of the seat member and the pressure plates. In the event of fire in the pipe line, the sealing ring and spacer rings disintegrate so that the spring means pushes the seat member.
