A method and apparatus for reliably assembling battery cell elements having relatively large numbers of electrode plates separated by a single interleaved spacer. The apparatus includes a rotatable element-assembly drum formed with a plurality of plate receiving slots at circumferentially spaced intervals about the periphery thereof, a first plate supply station for directing first electrode plate...

A resectoscope device comprises a sheath body having an elongated hollow sheath to be inserted into a urethra. A handle part has a slider connected to the sheath body and slides in the axial direction. An observing scope is inserted into the sheath through the handle part and sheath body. An electrode is inserted through the sheath, and is removably connected at the rear end to the slider. The ele...

A collapsible lamp shade includes a pair of resiliently compressible channel-defining members projecting inwardly from the interior surface of the shade cover to engage the periphery of a shade frame in a channel having an opening which is wider than the frame thickness. A structurally independent arcuately biased wire is selectively threaded into a sleeve at the lower edge of the cover to rigidif...

LAYING A PIPELINE IN ARCTIC OFFSHORE WATERS The present invention provides a method and apparatus for laying a pipeline in Arctic offshore waters with the use of a directional drilling technique, wherein pipeline segments (2, 6 and 9) are placed along arcuate underground paths, thereby minimizing exposure to ice gouging and eliminating the hazards associated with unstable permafrost. A special dri...

A tire curing system in which a number of mobile curing units, each designed to house a respective green tire, are selectively and independently fed along a loop circuit having at least two parallel branches, the ends of which branches are connected to a common section extending through a station for loading and unloading tires on and off respective curing units; each curing unit incorporating a m...

A hot tire forming method whereby at least some of the elements constituting each tire are formed starting from respective masterbatches, which are mixed with given chemical compounds inside respective continuous mixers to obtain respective final mixes, which are hot-fed to respective continuous production means, such as extruders, for obtaining semifinished products, which are hot-fed onto a fini...

Carboxymethyl cellulose (CMC) with a moisture content in the range of 12 to 25 weight percent water can be formulated with hydrocarbon oils, anionic surfactants and suspending agents to provide stable suspensions. The suspended CMC does not tend to settle out and/or compact during extended periods of storage.

A thermosetting organosiloxanic composition for protective coatings consists of a solvent and of the reaction product of four components, each one selected from one of following classes: (a) aminoalkoxysilanes; (b) formaldehyde or substances able to release formaldehyde; (c) alkyl- or alkenyl-acyloxy-silanes; (d) water; and is obtained by interreacting metered amounts of (a) and (b) components, by...

Low density particles or beads of polyphenylene ether or polyphenylene ether-polystyrene blends are provided by incorporation of a suitable blowing agent such as pentane into the resin mixture, flowed by expansion of the resin particles by exposure temperatures near the Tg of the blend.

Disclosed are hot-melt adhesive compositions comprising discrete particles of polyester adhesives, discrete particles of polyester containing a halogenated organic compound and discrete particles containing an antimony compound. Also disclosed is a method of incorporating both a halogenated organic compound and an antimony compound into a polyester adhesive composition.

The present invention relates to new water-soluble copolymers based on acrylic acid derivatives and their use as building material auxiliaries.

Cyclic polycarbonate (or thiol analog) oligomer mixtures are prepared by the reaction of bishaloformates or their thio analogs, or mixtures thereof with dihydroxy or dimercapto compounds, with alkali metal hydroxides and various amines. The oligomer mixtures may be converted to polycarbonates or their thiol analogs by a method which is particularly adaptable to integration with polycarbonate proce...

A power converter apparatus for a DC power transmission system or a frequency conversion system includes a control apparatus that functions such that during the operation of converters, when the output voltage of a constant reactive control circuit reaches the output voltage of a margin angle limited control circuit, a shunt reactor is interrupted or a shunt capacitor is closed, and when the outpu...
