Title: Extrudable thermoplastic hydrocarbon compositions
Inventor: LAVALLEE CLAUDE
IPC: C08L23/08
Filed: 1996-08-13
Abstract: Briefly, in one aspect, this invention provides a melt-processable composition comprising, in admixture: (1) one or more melt-processable thermoplastic hydrocarbon polymers as the major component of the com-position by weight, and, as a minor component of the composition by weight; (2) an effective amount of a chemically-resistant, fluoropolymer process aid to improve the processability of the composition. The fluo-ropolymer process aid contains at least about 50 weight percent of flu-orine and comprises one or more fluoropolymers which are essentially completely ethylenically saturated and consist essentially of interpolymer-ized units derived from the following monomers: (a) one or more fluori-nated olefin monomers having the following general formula: CF2=CXR1 wherein X is a hydrogen or a halogen atom; and R1 is a halogen atom or is an alkyl, cyclic alkyl, or aryl group having from 1 to 10 carbon atoms, and preferably it is either a halogen atom or a group having 1 to 2 carbon atoms; R1 groups may contain one or more heteroatoms such as nitrogen or oxygen and may be partially-, fully- or non-halogenated, provided, however, that whenever X is a hydrogen atom, R1 contains an allylic carbon atom relative to the .alpha.-unsaturation and that allylic carbon atom is not perfluorinated; (b) one or more olefin monomers of the gen-eral formula: CH2=CXR2 wherein X is a hydrogen or a halogen atom; and R2 is a hydrogen or a halogen atom with the proviso that R2 and X are not both fluorine; R2 may also be an alkyl, cyclic alkyl, or aryl group having from I to 10 carbon atoms, and preferably is a hydrogen atom or a group having 1 to 2 carbon atoms; and R2 may be partially-, fully- or non-halogenated and may contain one or more heteroatoms such as oxygen or nitrogen; and (c) 0 to 15 weight percent, of the total weight of the fluoropolymer, of one or more monomers that produce an acidic hydrogen on the backbone of the resulting fluoropolymer after polymerization. Component (2) has a Carreau-Yasuda Equation m1 parameter of about 0.7 or less, and the ratio of the melt viscosity of component (2) to the melt viscosity of component (1) is between about 0.01 and 100 at the melt processing conditions of the composition. The above-described admixture of components (1 and 2) may also be admixed with other conventional additives and adjuvants, such as fluorinated and non-fluorinated process additives, light stabilizers, antioxidants, fillers, antiblocking agents, and pigments. In another aspect, the present invention provides compositions such as those described above that further comprise one or more poly(oxyalkylene) polymers. Methods using these compositions to improve the processability of a melt-processable thermoplastic hydrocarbon polymer are also disclosed.

Title: An adiabatic process for producing dinitrotoluene
Inventor: WASTIAN DIETMAR
IPC: C07C201/08
Filed: 1998-10-08
Abstract: Dinitrotoluene (DNT) is produced by the adiabatic nitration of toluene with nitric acid at a temperature of from about 60 to about 200°C and at a molar ratio of toluene to nitric acid of from about 1:1.5 to about 1:3Ø The reaction mixture thus-obtained is concentrated to a water content of up to 30% by weight. The dinitrotoluene which is present in the reaction mixture is at least partially (if not completely) removed from the reaction mixture either before or after concentration of the reaction mixture. The DNT which is still present in the vapor generated during the concentration of the reaction mixture is kept liquid by the addition of a solvent to the vapors generated during concentration of the reaction mixture. The solvent added to vapor, together with any DNT present in the vapor is recovered. This solvent/DNT mixture may be recycled directly to the reaction vessel. The solvent/DNT mixture may also be separated. The separated solvent may be recycled to the solvent addition step. The separated DNT may be combined with the recovered DNT product or it may be recycled to the nitration reaction mixture.

Patent CA-2252413-A1 (CA)
Inventor: MATTEY DAVID E
IPC: E06B9/322
Filed: 1998-02-09
Abstract: An inventive bottom stop mechanism uses one of the lift cords (5) to operate.  While the cord (5) is unwinding from the shaft (9), the cord (5) leaves the shaft (9) along a line tangent to the shaft (9). As the last turn of cord (5) in unwound from the shaft (9), and the point of attachment of the cord (5) to the shaft (9) passes that point of tangency, the angle of the cord (5) with respect to the shaft (9) changes. This change in angle of the cord (5) is used to raise a pawl (15) which engages a ratchet wheel (13) to stop the shaft (9) and prevent further rotation in that direction. When the direction of the shaft (9) is reversed to again start winding the cord (5) thereupon, the cord angle returns to its prior value, releasing the stop.

Abstract: La présente invention concerne, non seulement un procédé permettant de conférer de la persistance directionnelle de pliage à une feuille, mais aussi l'appareil correspondant. Cette invention convient particulièrement à la fabrication d'éléments de structure, d'éléments de rembourrage et d'autres produits formant bloc pour l'emballage, et ce, à partir d'une feuille de papier ou d'autres matières recyclables. Le procédé comporte une troisième opération consistant à décaler les différents outils de pliage disposés sur une face ou sur les deux faces, la longueur du décalage suffisant à permettre le pliage de la feuille selon les divers traits de pliage. Le procédé comporte également une quatrième opération consistant à rétrécir les écarts entre les différents outils de pliage selon un rapport uniforme fonction de la valeur apparente du rétrécissement selon le sens de la longueur tel qu'il découle du décalage, et ce, en restant synchrone avec la troisième opération. La persistance directionnelle du pliage peut être conférée à la feuille le long des lignes de pliage avec précision et à l'occasion d'un processus industriel.

Patent CA-2254851-A1 (CA)
Inventor: HAUG WERNER
IPC: G07B17/00
Filed: 1998-03-10
Abstract: The invention relates to a facility for posting postal items which can be used by customers on a self-service basis. The measuring device integrated into said facility determines the volume of the postal item by lightly pressing a transparent plate onto the item from above. A digital camera determines the cross-sectional area of the item through the plate. At the same time, as soon as the plate applies the required pressure to the item, the height of the item is determined optically by means of a height code reflected into the optical system of the camera. Placing the plate onto the item largely prevents measurement errors possible with easily deformable items and, for example, when string or pieces of wrapping paper project from the parcel. The volume data obtained in this way can be taken into consideration in the postage calculations together with other variables (weight, distance to destination, etc.) that can influence the postage payable.

Title: Procedure and moulding unit for moulding pieces into a tire tread
Inventor: MERINO LOPEZ JOSE
IPC: B29K105/24
Filed: 1998-12-15
Abstract: The mold employs an insert with two types of section, one forming a support, another keying with it. When positioned on a section of the tire mold, the support projects from it. When located for molding, each key is assembled in its support. The mold is closed and the tread is molded. The keys are then extracted from the support(s). Finally, mold sections are retracted to the open position to extract the support(s). Independent claims are included for: the tire tread, made as described; the mold used, and the mold insert (10). Each key (16, 17) part-delimits an opening (20-23) of the insert. Each can be moved in a direction other than that of mold (11) opening or closing. The arrangement allows removal of the insert from the mold, without damaging the molding produced. Other preferred features of the insert are detailed. Preferred features: In the method, each key to be freed from its support in the molding insert, is moved in a direction differing from that of opening/closing of the mold section carrying the insert.
