An apparatus for depositing sheets (14) comprises a sheet depositing station (1,3), at least one suction roller (12.1, 12.2) to engage a sheet (14) being advanced horizontally towards the sheet deposit station (1,3), blower means (7) to blow such sheet (14) facially onto the deposit station (1,3), and suction means (10) disposed at lateral regions of upstream portions of the deposit station (1,3) ...

Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

In the production of sheets of paper from webs of paper, the longitudinal cuts and transverse cuts are made by laser beams. This method is particularly expedient when the cuts are to pass through a multiplicity of layers of paper. The laser cutting beams can be formed in their bundle in such a way that a focal line results which passes through the layers. Particularly well suited for copying purpo...

Vulcanising moulds for pneumatic tyres of vehicles are often provided with metal plates bent in a zig-zag shape and which are corrugated or which mould comparatively narrow incision-like depressions in the profiling of the tyre tread surface. In radially split moulds a problem results if the split joints between the mould segments extend in the direct vicinity of the corrugations or of the project...

A thread inserter and braking mechanism for a knotting apparatus used on spooling machines includes thread inserting and braking arms disposed on either side of the binding heads and external to the housing mounting the knotting apparatus. Brake pads disposed on either side of the housing cooperate with the thread inserter and braking arms and interact with the threads, retaining the threads to be...

Apparatus for separating sheets of piled packing material consists of a carrying device (10), a pile lifter (20) with a fork (21), temporary pile supporting fingers (32) and a singling station (40) with suction lifting devices (41). By means of a hydraulic cylinder (22) a pile (4) together with the fork (21) is lifted to the working level. The pile is reduced, one sheet at a time, at the singling ...

This invention concerns the manufacture of a layer of elastomeric material to form part of a pneumatic tire, and the manufacture of a reinforced elastomeric layer. According to the invention a layer of elastomeric material is formed as a progressive helical winding along a mandrel. The layer may be transferred in cylindrical form to a tire carcass building former to constitute an inner lining for ...

A safety ski binding includes an end piece engageable with a ski boot and horizontally pivotable on a body rotatably mounted on a pivot member carried on the surface of a ski for vertical pivotability with respect to the ski. The vertical pivot member includes two diametrically opposed cam faces movable in the longitudinal direction of the ski, each of the cam faces being engaged by a separate pis...

A sunshade having a cover which can be folded together in fan-like manner and is supported by at least three support struts, at least the outer two support struts having one end pivoted to a bearing member which is swingable around at least one horizontal axis on a stand bar and can be locked in position thereon and the outer two support struts can be pivoted via a spreading slide by one spreading...
