Abstract: A tension leveling system for thin metal strip has between a brake roll set and a tension roll set, additional two-roll bridles in which one or more inlet stretch leveling regions are followed by an elastic deformation region and the latter is followed by one or more stretch leveling regions. The stretch leveling regions can effect plastic deformation.

Abstract: A weld button for garments, i.e. a button, snap or interlocking fastener has fastener halves on two parts of a garment which are releasably joined and in which each of the fastener halves is affixed to the garment by welding two parts of the respective fastening half together.
Abstract: A household-use receptacle has a one-piece glass body having a side wall forming an annular upper edge defining an upwardly open mouth and having an inner surface and an outer surface and a floor unitarily joined to a lower edge of the side wall and forming with the side wall an upwardly open and laterally closed interior. The side wall is formed with at least one horizontally throughgoing hole having an annular inner edge. A decorative jewel is fixedly secured in the hole and projects horizontally past one of the side-wall surfaces.

Abstract: A downdraft boiler has a ceramic burner plate overlying a horizontal-tube heat exchanger at least the upper tubes of which each have an internal turbulator preventing premature vaporization of the water traversing the heat exchanger. The turbulator can consist of a twisted metal strip whose edges lie along helices.
Abstract: A motor-vehicle antenna has a monopole formed by a rigid circuit-board having a conductive trace, a socket for connecting a coaxial cable to the monopole, and a ground plane formed of rigid sheet metal or a circuit board and fixed to the monopole.

Abstract: A holding net having a net component, mesh or weave made of several pluralities of threads and an edge which is at least partially formed by an edge girth. The edge of the net has its edge girth made of the same material as the net mesh and threads or strands of the net mesh are woven into the girth.
Abstract: A hardened steel part of complex shape is made from a workpiece by first heating the workpiece to an annealing temperature. Then, while the workpiece is still at the annealing temperature, the workpiece is rapidly deformed by a machine into an intermediate shape. The deformed workpiece is then moved from the machine to a press, and, while the workpiece is still at the annealing temperature, it is deformed in the press to the complex shape and then held in the press to harden the workpiece.
Abstract: A bending press for bending metal plates for the production of large diameter pipe has an articulation for the upper die member which reduces bending moments as applied to the bending sword or ram. The articulation can be between the upper die and the foot of the bending sword and a second articulation can be provided between the bending sword and the head of it affixed to the head of the press.
Abstract: An apparatus for producing a melt blown web in which the collecting screen upon which the filaments are deposited passes over a plurality of suction regions or areas which have respective suction blowers and controls for the suction force and air throughput.

Abstract: The invention relates to an electromagnetic braking device for the steel melt running within the continuous casting ingot in a continuous casting unit. The electromagnetic brake device comprises at least one coil (3) with a ferromagnetic core (5), arranged on the broad side of the ingot and at least one yoke (7) provided on the above. In order to reduce the oscillating masses on the ingot components and to permit the retro-fitting of electromagnetic brakes to conventional continuous casting machines, the electromagnetic brake, comprising yoke (7), coil (3) and ferromagnetic core (5), is embodied such as to pivot inwards or outwards, preferably by means of two unequal length, non-parallel levers in or on the continuous casting ingot, using an actuator (6).
Abstract: The invention relates to biocidal polymers based on guanidine salts characterized in that they are representatives of a number of polyoxyalkylene guanidines and their salts and are a product of a polycondensation of guanidine salts with diamines which include two amino groups and polyoxyalkylene chains therebetween. In addition to a high bactericidity, these new polymer products are provided with a relatively low toxicity, an increased hydrophily, a quick and complete dilution in water, increased values of relative molar mass, and distinct characteristics of polymer surface active substances.

Abstract: A machine for cross cutting a material web has a main frame part unitarily formed with a pair of transversely spaced main sides and with at least one main traverse extending transversely between the main sides and a secondary frame part unitarily formed with a pair of transversely spaced secondary sides and with at least one secondary traverse extending transversely between the secondary sides. The main frame part is formed at its sides with a seat on which the respective sides of the secondary frame part fit complementarily with the main and secondary traverses extending parallel to each other. Two blade drums rotatable about respective transversely extending drum axes have ends journaled in the sides at the seat. Fasteners secure the frame parts together at the seat to opposite sides of the drum ends.

Abstract: The invention relates to a method and device for sandblasting, especially removing in a precise manner and/or compacting and/or coating solid surfaces, such as removing defective spots of paint from coats of lacquer, smoothing out soldered and welded joints, removal of contaminated concrete coatings or rust coatings, hardening, planing or coating metal surfaces, wherein a sandblasting agent is added by means of gravity and/or due to the effect of an injector to a carrier air flow produced by an underpressure, conveyed in a flexible hose- line system (13) to a jet lance (14) before being guided via a processing surface subject to low pressure by a sandblasting chamber, whereupon it is returned in the air flow, purified and returned to the circuit, whereby acceleration of the sandblasting agent is produced by the low pressure and the sandblasting chamber is displaced from one processing surface to another.
Abstract: An extruder drive has a housing, at least two extrusion worms each having a drive shaft extending into the housing, and at least one drive motor including at least one cylindrical stator fixed in the housing and a cylindrical rotor cooperating with the stator so as to be rotatably driven by the stator. The rotor surrounds the drive shafts, and each of the drive shafts is independently connected to the rotor for driving thereby.
