Abstract: In the embodiment shown is a handle to be mounted on a door stile, wherein the handle houses a latch plate, a bowed leaf spring interlocked with the latch plate, and a cam bar for moving the latch plate from one to the other of two positions, the cam bar being of such a length that one end thereof extends beyond one end of the handle when in one position and the other end thereof extends beyond the other end of the handle when in its other position. In both positions of the latch plate, its face is in a plane parallel to and confronts the stile. The latch plate has portions at one edge engaging an inner wall of the housing formed by the handle, and an elongated portion extending from such one edge passes through an opening in the wall and has a lip for latching to a jamb. When the door is closed, the cam bar in one position overcomes the spring to force the latch plate away from the jamb, and in the other position to permit the spring to position the latch plate wherein the lip thereof latches to the jamb.

Abstract: An improved articulated ball connector for use with pipelines as disclosed. In the illustrated embodiment, a sphere is attached to the end of a pipeline. A collar is fitted about the sphere. The collar has a surface contoured to match the surface of the sphere and its rotates or deflects through a designated angle. The collar has an encircling outer groove. A cup shaped receptacle receives the curved surface of the ball. The collar is abutted against a transverse shoulder on the cup shaped receptacle. The ball is pivoted relative to the cup shaped receptacle and the collar. A ring having a cross section which is U-shaped latches about the cup shaped receptacle and the collar. The U-shaped cross section includes upper and lower shoulders which protrude inwardly and engage the cup shaped receptacle and the groove in the collar. The ring is squeezed radially inwardly to clamp the cup shaped receptacle and the collar together.

Abstract: This improved gland assembly is primarily for use with mineral insulated cables. The same gland body and lock nut is used for cables regardless of the cable diameter. The dimensions of the compression ring are the same, except for the ring bore, which matches the diameter of the cable. The lock nut bottoms on a shoulder to prevent overtightening of the nut and risk of fracturing the sheath of the cable.

Abstract: An adaptor assembly is disclosed in two embodiments. Each embodiment is for connecting a tubing to a fitting of different size. The alternate embodiment is similar to the first embodiment except that it cooperates with a male fitting as opposed to a female fitting. In the embodiment for connection to a female fitting, a hollow threaded nut drives a tapered spool into a tubular seat, and the tubing is placed on the interior of the nut, spool and seat. All of this is placed in a hollow threaded adaptor which abuts a larger tapered spool, all of which threads into the female fitting. When the components are threaded together, they squeeze and clamp the tubing. The tubing, once clamped, is held securely and cannot be pulled free. The threaded adaptor has a wall thickness enabling it to mate with a fitting of any suitable size.

Abstract: A breech block connector for use in securing wash pipe sections together comprising sleeve means, pin means, box assembly means and locking means.

Abstract: A door lock for motor vehicles, in which a lock cylinder is connected with a lock tumbler by way of an insertable entrainment rod, whereby the lock cylinder is inserted together with a door handle into an aperture provided in the outer body panel of the door; an anti-theft device which is connected with the lock cylinder, engages from behind a locking projection provided at the door.

Abstract: A hydraulic coupling device for drawing and connecting two pipe flanges together, comprising a pair of clamps one of which is adapted for bolting the coupling device to one of the pipe flanges, and the other of which is movable towards and away from the first clamp by actuation of a hydraulic motor. An externally threaded spindle is connected to the motor and extends through an internally threaded bore in a sleeve on which the movable clamp is mounted, so that actuation of the motor causes the sleeve and movable clamp to slide lengthwise in the body bore as the spindle rotates. When the motor is reversed, the movable clamp swings radially away from the pipe to facilitate disconnecting the two pipe flanges. The coupling device also includes a hydraulic bypass switch to disable the hydraulic motor when the movable clamp arrives at a predetermined position.

Abstract: A beaded plastic tubing joint comprises:(a) relative flexible and tough plastic tubing having a rolled end portion forming a bead, said plastic being a high molecular weight polymer with characteristics of polybutylene, and(b) relatively rigid annular structure at opposite sides of the bead and pressurizing the bead annularly and through the wall thickness thereof to form an annular seal, and to retain the bead in position.
