Patent CA-2151351-A1 (CA)
Inventor: KASHIWAGI HIROSHI
IPC: B29C45/14
Filed: 1995-06-08
Abstract: Method and apparatus for manufacturing an elongate composite insulator with a satisfactory dimensional accuracy.  A core rod composed of a fiber-reinforced plastics is arranged within a mold cavity, and an unvulcanized polymeric material is injected into the cavity to integrally mold a sheath which covers the core rod over substantially the entire length thereof and a plurality of sheds which are spaced from each other in the axial direction of the core rod.  The polymeric material is injected into the cavity from a gate, with an injection pressure which acts in a first radial direction perpendicular to the center axis on a mold parting plane.  The core rod during injection of the polymeric material is supported from a second radial direction which is perpendicular to the center axis of the core rod and the first radial direction.  The deflec-tion of the core rod during the injection of the polymeric material is thereby minimized to realize a satisfactory dimensional accuracy of the product.

Patent CA-2153450-A1 (CA)
Inventor: LAZARECK JACK
IPC: B29B17/04
Filed: 1995-07-07
Abstract: A method is provided for processing a mixture raw automobile shredder residue, and virgin and/or contaminated synthetic plastic material, e.g., raw post consumer plastic waste. By means of this method, automobile shredder residue produced by a conventional automobile shredder is formed into a first stream by being ground in a first granulating zone to a reasonable small granular size using conventional equipment. A second stream comprising virgin and/or contaminated synthetic plastics material is ground in a second granulating zone. The two streams are combined to provide a processable mixture. The processable mixture is introduced into a high intensity mixer. The processable mixture is transformed into a semi-molten discharge stream by the kinetic energy imparted to the processable mixture by the mixer, while the mixer is substantially-simultaneously vented to remove and recover particulates therefrom. The particulates so recovered are recycled to an inlet which is upstream of the mixer. The semi-molten mixture emerging from the mixer is introduced into an extruder, or a press, where it is formed into a mass of the desired shape, and is cooled. This method allows for the production of useful, shaped masses from two different classes of materials which have been otherwise treated as waste.

Title: Process for the production of dinitrotoluene
Inventor: KLINGLER UWE
IPC: C07C205/06
Filed: 1995-08-07
Abstract: Dinitrotoluene is produced from toluene and nitric acid in the presence of sulfuric acid in a two stage process. In the first stage, toluene and nitric acid are reacted under isothermal conditions in amounts such that mononitrotoluene is produced. The reaction mixture is then separated into an organic phase and an acid phase. The organic phase is then further reacted with nitric acid under adiabatic conditions to produce dinitrotoluene. The reaction mixture is then separated into an organic phase and an acid phase. Dinitrotoluene is recovered from the organic phase. After at least 5% by weight water is removed from the acid phase and sufficient nitric acid to replace that consumed during the nitration reaction has been added, the acid phase may be recycled.
