The invention concerns a method for manufacturing of square pipes from coated steel strips. Both sides of the strip are coated with metal, say zinc or aluminium. The strips also can be industrially painted e.g. with PVC-plastics directly upon the steel surface or upon the metal-coated surface. The shaping is carried out in a continuous roller shaping device by at first shaping a profile (6) with a...

A description is given of a lead storage battery having at least one separator made of filled polyolefin with which the formation of coloured, generally dark and frequently sticky deposits encountered in practice is reduced in terms of quantity. This is achieved because one or more non-ionic surfactants having a certain structure and an HLB value of at least 5 are present in the storage battery. A...

Prodn. of a shrinkable sleeve made of polymer material, includes extruding a base member, wetting, stretching and cooling. Wall protrusions are formed by the partial bringing together of longitudinal wall sections. The protrusions are shrunk by heat treatment. The base member is pref. coated with adhesive on the inside, and the adhesive is activated by heat treatment. ADVANTAGE - The sleeves can b...

A yarn splicer employs aero-dynamic forces through air channels in an outer block serving sections in the inner yarn channel, which splay the yarn ends, then opposing tangential twist is applied above and below the splay, which joins the ends together. The inner block (4) has a yarn entry slot (3) into the tubular splicing channel (2). Connected to this channel are two slots with air entry at (12...

The cage portion of a cage and roller assembly has two annular end rims joined by cross-bars around the periphery of each rim. The rims and cross-bars define multiple pockets which hold the rollers. The cross-bars are configured to contain the rollers within these pockets; in addition, coined ramp surfaces and land surfaces on the cross-bar outer surfaces extend radially outward farther than the o...

PURPOSE:To prevent display quality from lowering due to light reflection with a spacer by oppositely disposing a pair of substrates provided with a plurality of electrodes with a spacer interposed in between, and making the spacer an opaque glass ball by devitrification. CONSTITUTION:A pair of substrates with at least one of their surfaces provided with electrodes 13, 14 are oppositely disposed on...

PURPOSE:To restrain deterioration of a light emitting layer caused by permeated moisture so as to achieve long life of a distributed electroluminescence element by covering the side face of a laminated body by means of the peripheral portion of a water collecting layer, the laminated body comprising a transparent electrode, the light emitting layer, a dielectric layer and a back electrode. CONSTIT...

PURPOSE:To prevent lowering of luminance of a thin film electroluminescence element by introducing two kinds of specific mixing gases into a reactor while preventing them from making contact with the injection opening of a nozzle, and then mixing them together, and accelerating their vapor phase growth chemically so as to form a film. CONSTITUTION:A mixed gas containing an organic zinc compound an...

Each transport device contains at least two drive wheels which are driven at individual speeds VA and VB and which are pivotable by related steering angles alpha and beta . Identical servo-drive units are associated with the drive wheels and their mode of operation and mutual coupling is adapted by switch devices to the steering angles alpha and beta such that the required speed adjustment ...

A generally cylindrical wall member (14) of resilient material has an opening (22) extending axially of the container (10) for inserting beads (12) into individual compartments (54) in the container (10). Axially extending sides (30) of the wall member (14) are resiliently movable radially outwardly to grip and hold the beads (12) during transporting. The curvature of the sides (30) is such that a...

The invention concerns a microprocessor with a watchdog circuit which monitors the correct progress of the processor programme. The watchdog circuit must be addressed at given time intervals by the microprocessor since it will otherwise execute an operation such as resetting the microprocessor to the beginning of the programme. In order to symplify the design, it is proposed that, when an error fu...

The circuit has a trigger input (E1) coupled via a capacitor (C3), resistor (R11, R12) and diode (D1) to one input of a comparator (S2).
