Abstract: A method of manufacturing polychromatic artificial yarns incorporating liquid crystals is provided.According to this method, a transparent film sheet of plastic or other suitable material having a row of a plurality of longitudinally extending grooves on its outer surface is prepared and then coatings of micro-encapsulated liquid crystals, and particles of an ultra-violet light adsorbent are applied onto the grooves. After these processes, the entire outer surface of the film sheet is coated with a thin layer of carbon black and is then covered adhesively with another transparent film sheet of the same material. The entire material is finally cut out, across the second and first mentioned film sheets, longitudinally along the grooves to produce linear strips to be spun into yarns.

Abstract: A memory device and method is disclosed wherein positions of ions associated with a film are varied locally with respect to the film's surface by an electric field. A writing and erasing field is created by voltage modulating the film's conducting substrate in synchronization with low intensity electron bombardment of a local area of the film's surface by a scanning electron beam.The ion's position in the film varies the film's surface potential and alters the angular distribution imparted by its surface to primary diffracted and secondary emitted electrons. In the invention's read mode a scanning electron beam, combined with a detector discriminator, analyzes these emitted electrons to determine the surface potential at each address on the film thus reading out data stored in the film. A second means of reading out stored information utilizing detection of low energy electrons selectively diffracted by ions near the film's surface is disclosed.

Abstract: An apparatus for the periodic transverse welding and severing of longitudinally advanced superposed wrapper sheets has two oppositely rotating, cooperating welding shoes, at least one of which is provided with a heater and at least one of which is displaced towards its rotary axis by virtue of the engagement between the welding shoes during each revolution thereof. One welding shoe has a tapered terminal head which includes leading and trailing flanks as well as a cutting edge. The other welding shoe has a counterface cooperating with the cutting edge and two elastic, rod-like members arranged adjacent and parallel to the counterface. As the welding shoes simultaneously engage the superposed wrapper sheets from opposite sides, the leading flank of the tapered head, cooperating with one of the elastic rod-like members pinches the wrapper sheets and provides a first transverse weld seam.

Abstract: A strip of rubber base bonding material for use in cold bonding a prevulcanized tread strip to a tire contains both a low-temperature vulcanizing agent and accelerators. The bonding material is compounded by a special technique which stabilizes the vulcanizing agent and the accelerator thereby avoiding prevulcanization during storage. In use the bonding material is interposed between the tread strip and the tire, and the assembly is heated to less than about 300.degree. F under pressure to effect vulcanizing of the bonding material.

Abstract: Apparatus for laminating film strips to a transport web, the laminating apparatus adaptable to handle film strips of different sizes having different perforation formats. The laminating apparatus comprises a module for positioning a film strip of a particular film size with respect to the transport web. The film strip and the transport web are then advanced through a laminating station where they are laminated together with a tape. The laminating apparatus is designed to interchangeably receive the positioning module. Thus, film strips of different film sizes may be laminated using the disclosed laminating apparatus by interchanging the positioning module to suit the particular film size to be laminated.

Abstract: In the fabrication of integrated circuits, a method is provided for forming dielectrically isolated regions in a silicon substrate comprising initially introducing conductivity-determining impurities into the substrate to form at least one region of one-type conductivity at the surface of said substrate. Then, a mask comprising a composite of a bottom layer of silicon dioxide and a top layer of silicon nitride is formed over at least a portion of the surface of said introduced regions. The substrate is then subsequently thermally oxidized to an extent sufficient to form regions of recessed silicon dioxide abutting and thus laterally defining said region of one-type conductivity. In this manner, it is ensured that the recessed silicon dioxide will abut introduced region irrespective of the extent of the "bird's beak" normally associated with thermal oxidation utilizing silicon dioxide-silicon nitride masking.

The pipe section is joined to the fitting by heating the pipe end sufficiently to soften it, heating the insert portion of the fitting so as to soften its exterior wall, inserting the fitting so that the end edge of the pipe section substantially abuts the shoulder portion of the fitting and crimping to cause fusion of the pipe to the fitting. For additional strength, the fused pipe joint assembly may be provided with an externally positioned sleeve.

Abstract: Method for splicing optical fiber cables which applies to those cables having an axial core and fibers disposed around the core, parallel to the cable axis or having a slight slant with respect thereto. At the places where splicing will have to be made, when the cable is laid down, the jacket of the cable is removed the fibers are glued on the core and two half-shells are disposed round the glued fibers and encase them. The half-shells are bonded to the core and fibers by gluing under pressure. When the glue has set, the half-shells together with the fibers and cable core are sawn perpendicularly to the cable axis which gives two half-shell segments. These segments have registering bores and splicing is achieved by inserting calibrated columns or pins into these bores.

Abstract: Sheaths for covering battery electrodes are produced by introducing inner and outer layers of sheath material onto a plurality of adjacent mandrels. As the layers pass along connector sections of the mandrels, they are connected together to form interconnected tubes. The connector sections have an elongate cross-sectional configuration to facilitate such connection. Thereafter, the layers pass along reshaping sections of the mandrels which have a cross-sectional configuration that is different from that of the connector sections and which corresponds to the desired final shape of the tubes.BACKGROUND AND OBJECTSThe present invention concerns the manufacture of a type of sheath for tube electrodes used with electrical accumulators or batteries; it comprises two layers. One of the two layers, the actual or inner sheath wall, comprises a layer of fibrous material, preferably glass fiber. The sheaths comprise another layer outside the fibrous material.
