Abstract: IMPROVED PROCESSABLE RADIATION CURABLE          POLY(VINYL CHLORIDE) RESIN COMPOSITIONS                           Abstract This invention relates to radiation-curable poly(vinyl chloride) resin compositions that can be processed to form shaped articles, coatings, and films. Poly(vinyl chloride) resins are generally characterized by low impact strength.  To remedy this shortcoming, radiation curing of compositions of poly(vinyl chloride) resins containing various plasticizers and crosslinking agents has been utlized.  However, certain cross-linking agents cause radiation-cured poly(vinyl chloride) resins to become cloudy and exude oily materials upon storage.          It has been discovered that poly(vinyl chloride) resin compositions containing an ethylenically-unstaturated compound having carbonylamino or thiocarbonylamino groups are readily convertible at low temperatures to crosslinked polymers and are radiation-curable to dimensionally stable articles and films that are clear and that do not exude oily materials.          The cured poly(vinyl chloride) resin compositions of the invention are useful in the form of such shaped articles as self-supporting films, foils, and sheets and as coatings.  The compositions of this invention are particularly useful as a sheet for a tape support for an adhesive and as coating compositions for substrates such as wire and flat cable insulation.

Abstract: Abstract The multiple pressure condenser has heating de-vices (33, 34) for the undercooled parts of the condens-ate, which devices are accommodated alone or preferably in  pairs in one or more of the condenser parts.  The heating devices (33, 34) have perforated droplet plates (50, 55) located one above the other, from which droplet plates the undercooled condensate drips downwards in steps and is heated to at least the saturation tempera-ture of the condenser space by high pressure exhaust steam flowing upwards.  The undercooled condensate arrives at the highest droplet plate via drain and rising ducts (46, 47 and 48, 49 respectively), which are con-nected to the space over the intermediate floor or floors which separate the exhaust steam spaces from the hot well.

Abstract: Abstract:    An apparatus for molecular beam epitaxy is constructed so that a substrate is introduced into a vacuum vessel with the substrate surface for epitaxial growth facing downwards. The substrate is conveyed to and transferred into vacuum chambers for performing processes necessary for the epitaxial growth while the substrate surface is maintained facing downwards and without directly touching the substrate surface.  The result is less surface contamination and a higher rate of production of successful products.

One of the casting nozzle and the crucible is movable toward the other for immersing a lower end of the casting nozzle in the molten casting material in the crucible.  The housing is connected to an inert gas source for introducing inert gas into the chamber when the casting material in the crucible is melted.  When the lower end of the casting nozzle is immersed in the molten casting material, the molten casting material is moved along the casting nozzle by the pressure of the inert gas in the chamber.  A cooling device is associated with the casting nozzle for solidifying the molten casting material when it is passed through the casting nozzle, thereby forming the elongated cast product.

By listening-in on the exchange of information between the subscriber station and an exchange over a message transmission channel a fraudu-lent user can overhear the identification and consequently utilize the services of the exchange by imitation of the external identification.  To enable the detection in the exchange of an illegally copied identification of a sub-scriber station, the exchange transmits a continuously changing encoding rule for forming the identification of the subscriber station, or the identification of the sub-scriber station is based on combining fixed and variable data.

Abstract: ABSTRACT OF THE DISCLOSURE:         A method and a device for forming objects by injecting thermoplastic materials.  When performing the method for forming objects by injecting thermoplastics into a mould, the melt of thermoplastics is injected into a heated mould, heated over the temperature of a glass tran-sition of amorphous polymers or over the temperature of melting of semicrystallic polymers.  The mould is heated by means of a heating medium, which is supplied into the space surrounding the forming space; the temperature con-trolling medium heats the forming surface before the injec-tion, and cools it down after the mould has been filled up. The apparatus for performing this method comprises espe-cially an adapted mould, the forming space of which is surrounded by forming walls, represented especially by thermally conductive foils, around which a temperature controlling space is made, being connected to a source of temperature controlling liquid.
