Abstract: An electric welding muff for joining thermoplastic line elements comprising a welding sleeve and an electrical resistance heating wire. The sleeve is formed of thermoplastic material. The heating wire is wound in a plurality of turns and embedded in the sleeve adjacent one of its lateral surfaces and has peripherally spaced deformation points diverging from the general course of the turns. During manufacture and welding, the heating wire remains in its predetermined position since expansion of the wire is absorbed at the deformation points.

Abstract: Pipe components, i.e., pipes, adapting members and fittings made of weldable plastic, are interconnected by electrically weldable joints. The welding process is made possible by a welding sleeve 3 being connected to the output 4 of the device. A switch-on monitor 11 permits the switching on of a switch stage 7 of the welding current circuit. The thermal energy is determined by square-law simulation of the welding or mains voltage in a pulse generator 9, which produces a pulse frequency which is dependent on this value and whose pulses are summed in a counter 10. Once a count value that corresponds to the thermal energy has been reached, the switch stage 7 is switched off. If the count value is not reached a function monitor 5 gives a warning signal.

The slats have end fittings which are selectably insertable in the slots with the bottom of each slat resting on the one below so that the slats define a generally curvilinear surface having predetermined curvatures. Devices for holding straps and pads to apply lateral forces in a predetermined manner are also provided. Specific slat structure and full adjustability is provided.

Abstract: A highway median barrier construction is disclosed wherein the barrier is formed as integral U-shaped shell sections of polymer concrete which are placed end-to-end at the construction site and are then filled with hydraulic concrete or other ballast through filling holes which are then capped with polymer concrete.

Abstract: A locking assembly for normally separable apertured structures which protect business fronts against burglary. The locking assembly includes a sturdy, straight pin which penetrates all apertures, and is part of a sturdy bracket which overlies a fixed standard or post. The arrangement is such as to permit a key operated locking device to lie flatly and directly upon the bracket so as to prevent removal of the bracket and its above mentioned pin. The overall arrangement is such as to guard against burglary by an unauthorized person using forceful tools, and to prevent access to the pin for the purpose of destroying or cutting it.

Abstract: A hinge assembly which allows pivotal movement between first and second panels of at least 90.degree. and which allows separation of the two panels anywhere along the pivotal movement. The assembly has a hinge member formed of a single piece of bent sheet metal. The hinge assembly comprises a first portion located on the first panel, a lip extending substantially perpendicularly from the first portion, and a hinge member rigidly coupled to the first panel and having an intermediate portion extending substantially perpendicularly from the first panel and a leg extending substantially perpendicularly from the intermediate portion towards the lip. The distal edge of the lip and the distal edge of the leg define a slot which receives a second portion located on the second panel to thereby pivotally couple the first and second panels.

Abstract: A tool for forming a pipe joint of the type wherein a ring with a frusto-conical inner surface is forced over the belled one of two telescopically assembled pipes includes a jaw assembly having two pairs of jaws which are axially movable toward each other, one pair to engage the bell shoulder and the other to engage and push the ring. A pressure clamp has two forks shaped to engage the ends of the jaw assembly and a piston and cylinder assembly to linearly move one fork toward the other, thereby moving the jaws and forming the joint. The size of the jaw assembly can be selected according to pipe diameter.

Abstract: There are disclosed thermoplastic and thermosetting polymers which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the polymer by reacting a monomer or polymer containing at least one free carboxyl group with a reaction product of tungsten or molybdenum and pyrrolidine.

Abstract: A lock with a stator and a rotor having a key slot or channel for receiving a flat key has four tumbler rows with pin tumblers, the rows extending in the axial direction of the rotor. The planes containing two of the tumbler rows are inclined by identical angles on opposite sides of the median longitudinal plane of the key and intersect a narrow edge surface of the key adjacent the corners so that the recesses in the key to receive the pin tumblers open on both the narrow side and the flat side key, making it possible to reduce the constructional size of cylinder lock.

Abstract: Working sails, typically headsails and mainsails, are furled while aloft by providing flexible sheet material extending along the sail from head to foot, at least preliminarily furling the sail from leech to luff, progressively forming the flexible sheet material into a tubular bag extending from head to foot and enclosing the furled sail, and progressively securing the bag against opening.

Abstract: Electric welding sleeves used more particularly with larger pipe diameters have a heating wire winding which is under compressive stress due to the shrinkage of the sleeve member. This compressive stress and the elongation of the resistance heating wire occurring during the welding process can lead to a lateral displacement and contact with adjacent turns. The welding apparatus (4) used for welding such sleeves obviates these difficulties in that the overall welding time of the electric welding sleeve (15) is subdivided into a preheating time and a welding time. During the preheating time a partial power is used and during the welding time the full welding power. If the welding power is taken from an alternating current system the welding process can start with half the power by arranging a diode (8) in the welding circuit (2) and at the end of the preheating time the diode is bridged by a switching stage (10).
