Abstract: An apparatus for pulling a tubular film down over a large object has at least two guide and roller assemblies each flanking the object and each movable vertically along the object. Each assembly has a guide, an outer roller and an inner roller. The film is gathered by positioning the assemblies in an upper position, orienting the inner rollers generally below the outer rollers, and rotating the rollers while gripping the hood between them to pull the tube down and form it into folds beneath the roller assemblies. The film is pulled down over the object by orienting the inner rollers generally above the outer rollers, and then shifting the roller assemblies downward while rotating the rollers so as to pull the tube up and unfold it.

Abstract: A circuit for detecting the presence, position or the approach of an object in an observation area, the circuit has a sensor electrode assembly with an electrode that forms part of a capacitor system whose capacitance relative to a reference potential (e.g. ground) is dependent on the presence, position or approach of objects in the observation area. An evaluation circuit coupled to the sensor electrode detects a phase shift of the capacitance of the condenser system. An LC network is coupled to the capacitor system, and an oscillator connected to the electrode applies a frequency to the system formed by including the electrode and the LC network at a frequency within the range of a parallel resonance frequency of the LC network.

Abstract: A headrest has a generally stationary support, a headrest body having a forwardly directed front face and positioned such that a head of a user seated in front of the support is generally level with the body, and a guide securing the body to the support for vertical movement relative to the support. A drive can vertically shift the body relative to the support. A sensor assembly has at least three horizontally elongated and vertically spaced electrodes carried on the front face. A controller connected to the electrodes and to the drive means detects a vertical position of the user's head relative to the body and displaces the body so as to centrally align with the user's head.

Abstract: A metal strip is stretched as it is moved longitudinally generally continuously between an upstream traction-roll set and a downstream traction-roll set. The roll sets are differentially driven—with the downstream set moving at a slightly higher peripheral speed than the upstream set—so as to apply to the strip in a region between the sets a tension generally equal to a stretch limit of the strip. The strip is locally heated or cooled at an upstream location in the region between the roll sets so as to set in the strip in the region a temperature distribution that is nonhomogeneous transversely across the strip at least immediately downstream of the upstream location.

Abstract: An apparatus for sealing a cover film to a blister film having blisters holding respective small objects has a feed roll rotatable about an axis and formed with an array of radially outwardly open recesses arrayed like the blisters of the blister film. The blister film passes over the feed roll with the blisters in the recesses. A sealing roll is rotatable about an axis generally parallel to the feed-roll axis and presses the cover foil down against the blister foil on the feed roll. The feed roll is rotated to pull the films in a travel direction between the rolls so that the cover film is sealed to the blister film between the blisters thereof. A sensor detects movement of the sealing roll transversely of the feed-roll axis. A controller generates an output when the detected movement exceeds a threshold.

Abstract: The invention relates to a method for joining cathode metal sheets to form crude strips that can be coiled and rolled and for the production of metal strips of a constant thickness from crude strips that have been produced from cathode metal sheets of varying thicknesses. The aim of the invention is to produce metal strips of a high purity that are devoid of non-metallic inclusions. The method can be used whenever highly pure and/or inclusion-free metal in strip or foil form is required in large quantities. The application of said method is only limited by the fact that the metal is deposited electrolytically on cathodes, and if permanent cathodes are used, must be separated from said cathodes without fragmentation. This is possible with the following metals: lead, zinc, tin, copper, nickel, cobalt, cadmium, iron and gold.

Said insertion opening is produced by at least one pair of lamella (8a, 8b), formed on the side walls, the lamella tapering towards one another in the manner of a funnel and forming an expandable funnel slot. The protective housing (102) comprises two housing parts which can be inserted into each other. The inner housing (2a) comprises the pair of lamella (8a, 8b) and an outer housing (11), which surrounds the inner housing (2a), is embodied as a sleeve that is less elastic than the inner housing (2a).

The tape forms a loop to a side of the buckle opposite the outer end. Structure forms an eye through which the loop passes and through which the tape can slide.

Abstract: The invention relates to a method for expanding the use of a coiling and uncoiling station (coilbox) located between the roughing train and the finishing train for rolled strip material in hot-rolling mills. The use of said coilbox is expanded by impinging the coil that is to be uncoiled with a pressing force (F) which acts in the direction of the roller table (4) and/or placing the coil in a depression of the roller table in order to process smaller coil weights in a spikeless coilbox, and/or by combining, in a chronological and weight-related manner, the active transfer and passive transfer of a coil from a first coiling station to a second coiling station in order to increase the throughput especially at average coil weights in a spikeless coilbox, and/or by supplying heat to the strip upstream or downstream of the spikeless coilbox and/or thermally insulating the strip or the coilbox in order to variably increase and homogenize the strip temperature.
