Abstract: Novel processes for preparing a heat shrinkable film by first forming a polyolefinic film on a three-roll calender in which the second and third rolls rotate at about the same speed and the first roll rotates at a slower speed, the top roll is heated to a temperature above the melting point of the polyolefinic material, the middle roll is heated to an elevated temperature below its melting point, and the bottom roll is chilled relative thereto; thereafter subjecting one surface of the resulting film to irradiation from a low energy electron beam at a voltage such that the irradiation dose at the half-depth of the film is approximately one half the dose at the irradiated surface and at a current to film surface speed ratio such that the surface dose would effect crosslinking sufficient to impart to said film a 100% modulus at 150°C of from about 10 to about 100 pounds per square inch, if the dose at any depth in the film were substantially equal to the surface dose; and then subjecting the opposed surface of the film to irradiation from a low energy beam at a voltage and at a current to speed ratio substantially equal to that in the preceding step, such that the 100% modulus at 150°C of the film as a whole is about 10 to about 100 pounds per square inch and the film is characterized as being substantially uniformly crosslinked throughout its thickness.  In the preferred embodiment of this invention a per se known adhesive layer may be applied to provide a heat shrinkable adhesive tape.

Abstract: Method and apparatus for applying a programmable pattern to a succession of moving objects, comprising a microprocessor for storing a user defined value representing the length of the pattern, a clock for generating a series of pulses and a photo-eye for detecting the presence of the succession of moving objects.  Upon detecting the presence of a first one of the moving objects, a set-up mode gate is enabled for transmitting the clock pulses to a first divider circuit.  The first divider circuit divides the number of transmitted clock pulses by the user defined value and in response generates and stores a first count value.  Upon detecting the presence of subsequent moving objects, a run mode gate transmits successive predetermined numbers of clock pulses to a second divider circuit.  The second divider circuit divides the successive predetermined numbers of clock pulses by a first count value and in response generates successive further count values.  A microprocessor compares the successive further count values with the user defined value and in the event the values are equal initiates application of the programmable pattern to the succession of objects, and in the event more than a predetermined number of the successive further count values are not equal to the user defined value the microprocessor re-initiates the setup mode procedure.

Abstract: PLASTIC PIPE WITH LOCKING INTEGRAL END CONNECTION          ABSTRACT OF THE INVENTION    Plastic, such as polyolefin, pipe having a locking integral end connection. The pipe is fabricated with male and female end connections in order that the pipe may be press-fitted together with the interior and exterior forming a flush uninterrupted surface. One or more radial ribs and grooves are formed on the interior of the female connection while a registering series of ribs and grooves are formed on the exterior of the male connection. The ribs and grooves are of an interfitting wedge shaped   configuration to provide a locking engagement to resist any tendency for separation. Interfitting corners of the ribs and grooves may be rounded to distribute stress and minimize damage when the pipe ends are fitted together.          The ends of the pipe are bevelled in order that the ends pressed together engage and by the slight resiliency of the polyolefin pipe construction permit the slight expansion and contraction of the ends to provide a locking interfit of the respective ribs and grooves in the two ends. A reinforcing sleeve may be used over the coupling for additional strength.  The wall thicknesses of the end connection and width of the ribs and grooves are particularly dimensioned in order that the male end may be inserted to a complete lock position without premature engagement.

Abstract: The present invention comprises a method of preparing vinyl chloride polymers or vinyl chloride copolymers suitable for the preparation of plastisols. The method can be used at polymerizations, wherein a pre-emulsion of a substance having a very low solubility in water, is caused to swell by the vinyl chloride monomer, whereafter the monomer emulsion abtained is subjected to polymerizing conditions. According to the invention the emulsion is stabilized, and, by polymerizing in the presence of an stabilizing latex, it is possible to avoid, that the obtained latex becomes instable. In this way it is possible to prepare polymers having a particle size and a particle size distribution giving a product with low viscosity at the preparation of plastisols.

Patent NL-92723-C (NL)
IPC: C09K23/00
Abstract: Dyeable films, fibres and fabrics are made by treating with a strong oxidizing agent, preferably in an acid medium and at an elevated temperature, a shaped article made from a polyacrylonitrile or copolymer of acrylonitrile substituted by a group containing bivalent sulphur (see Group IV (a)).  The introduction of the bivalent sulphur group may be effected on polymers whilst in shaped form and this method of operation may be used to produce locally oxidized structures, e.g. a fabric made from fibres of a copolymer of acrylonitrile containing halogen alkyl agroups is printed with a thiourea or thiocyanate in the presence of thickening agents such as methyl or carboxymethyl cellulose and then reacted by heating, followed by treatment with an oxidizing agent; alternatively a fabric made of an acrylonitrile polymer containing bivalent sulphur groups may be oxidized locally by means of an oxidizing agent in the presence of a resistant or thickening agent such as sodium polystyrene sulphonate.  The products of the process show affinity for dyestuffs, particularly basic dyestuffs such as Astra Cyanine B, a triphenylmethane dyestuff.ALSO:Dyeable shaped structures are made by treating with a strong oxidizing agent, preferably in an acid medium and at an elevated temperature, and prior to or after a shaping process, a polyacrylonitrile or copolymer of acrylonitrile substituted by a group containing bivalent sulphur which is either linked directly to a saturated carbon atom of the chain or is linked to the chain by another saturated carbon atom and in which group another carbon atom, adjacent to the sulphur, is linked by more than one valency to another sulphur atom or to oxygen or nitrogen.  The sulphur containing groups may be incorporated in the polymer molecules (a) by copolymerizing acrylonitrile with vinyl thioacetate in a dioxane solution with azodiisobutyronitrile as a catalyst, or (b) by causing polyacrylonitrile or copolymers of acrylonitrile to react with compounds such as sodium and ammonium thiocyanates, sodium alkyl xanthates, alkali thio- or dithio-carbamates, ethylene thiourea, N-butyl ethylene thiourea and mercaptobenzothiazole; preferred polymers are copolymers of acrylonitrile with monomers containing reactive groups such as vinyl chlorethyl ether, chloracrylonitrile, chlorethyl methacrylate, hydroxyethyl acrylamide benzene sulphonate, bromobutyl acrylamide and vinyl chloroacetate, and, optionally, other monomers such as methyl acrylamide, vinyl acetate and vinyl pyrrolidone may also be present.  Specified oxidizing agents are chlorine or bromine in the presence of water, hypochlorous or hypobromous acid, benzoyl peroxide peracetic or perbenzoic acid, N-chlorurethane and N-chloroxazolidone, the action of which may be accelerated by means of oxygen carriers such as anthraquinone or anthraquinone sulphonic acid.  The oxidation reaction is preferably carried out on the polymeric material in the form of fibres or films which may then be dyed, particularly with basic dyestuffs.
