Abstract: ABSTRACT OF THE DISCLOSURE         An improved thermoplastic pipe stub end for welding to thermoplastic pipe is disclosed.  The stub end has a flange portion integrally joined to a neck portion which has inner and outer surfaces and terminates at a welding face.  The improvement resides in the reduction of the length of neck portion such that it extends from the flange a distance in millimeters of not greater than 1.5  , where O.D. is the outer diameter in centimeters of the neck portion at the weld-ing face.  The improved stub end permits higher strength heat welds to be made by butt fusion between the thermoplastic stub end and a thermoplastic pipe to be joined thereto.

Abstract: ABSTRACT OF THE DISCLOSURE A puffer-type circuit interrupter comprises a cylinder coupled to the conductive contact rod of the inter-rupter and a floating piston within the cylinder that is relatively movable with respect to the cylinder to pressurize fluid in the cylinder, which pressurized fluid is used for arc-extinguishing purposes.  Means effective during an interrupting operation is provided for forcing current flowing through the rod to follow a loop-shaped path, electrically in series with the rod, that extends through the piston.  This current has a magnetic effect while flowing through said loop-shaped path that acts to drive the piston within the cylinder through a fluid-pressurizing operation.

Abstract: ABSTRACT            The invention relates to a device which is for use as or as part of mechanical handling apparatus. It includes an elongate body, and, in the embodiment described, a support for supporting the load and an internal member housing rollers and which is movable above and below the support by an in-flatable device in the form of an air bag.  The body member is elongate so that it forms a kind of track and it includes a stop in the form of a plate which can be moved between a position in which a load can be moved along the track and a position where it prevents or hinders movement along the track.  The track can thus be kept "live" during all loading and unloading operations and the stop keeps loads in their desired positions on the track both during handling and trans-port.

Abstract: CURRENT CONFINEMENT IN SEMICONDUCTOR DEVICES     Abstract of the Disclosure Current confinement in semiconductor device by means of buried high resistivity zones is described.          For example, in a stripe geometry, semiconductor, junction laser the laterally separate, high resistivity zones, which confine current flow in a narrow channel between the upper and lower electrical contacts, are buried below the upper contact. This configuration permits current to flow from the upper contact into the body of the semiconductor over greatly increased area before it enters the channel.  The current density at the interface between the upper contact and the semiconductor body is thereby reduced, making the quality of that interface less important.  Several processes which employ proton bombard-ment for fabricating the laser are also described: (1) in one the normal sequence of Zn diffusion and proton bombardment is reversed, and (2) in the other the profiles of Zn doping and proton damage are suitably tailored.                              - i -
