Patent CA-2135640-A1 (CA)
Title: Flooring system
Inventor: KONGSGAARD BJARNE
IPC: A01K1/015
Filed: 1993-05-13
Abstract: A flooring system consists of a number of frames (1) equipped with a toothing (9, 10) on opposite lateral edges (7, 8). The toothing consists of teeth (12, 13) connected, at each tip, with a downward lateral wall (19) which delimits a U-shaped track (11). The lateral wall (19) is, at its upper side, projected from either side of the tip of the tooth (20) so that surfaces (21) pointing up-wards are formed. These surfaces may be used as contact surfaces for engagement under the roots (22) of teeth of an adjacent grate (1). Due to the engagement of the contact surfaces (21), a grate will not be able to loosen unintendedly from a floor, and consequently such a flooring system will be particularly well suited for use in pigsties.

Title: A method for manufacturing low bark content wood chips from whole-tree chips
Inventor: SEPPANEN VELI
IPC: B07B15/00
Filed: 1993-06-08
Abstract: The object of the invention is a method for manufacturing low bark content wood chips from whole-tree chips, in which method there are two or more sequential separation stages, which can be di-vided into pre-separation with a bark content of less than 10 % and final cleaning, and in which the pre-separation consists of at least pneumatic separ-ation and the final cleaning includes sorting based on colour difference. According to the invention, before pneumatic separation the bark is removed from the chips by grinding, which simultaneously reduces the particle size of the bark.

Patent CA-2150154-A1 (CA)
Inventor: KO YA-TIEN
IPC: H04L29/06
Filed: 1995-05-25
Abstract: A method and apparatus for generating a conformance test data sequence of minimal length to verify that a device conforms to a protocol entity which can be characterized by a simplified extended finite state machine. The method generates an expanded directed graph of the protocol wherein each state is represented by a state vertex and a dummy vertex which are connected to other similar state and dummy vertices by directed edges in a configuration corresponding to the operation of the machine. The directed edges are then assigned traversal numbers corresponding to the minimum number of times a respective directed edge need be traversed in order to test values in a predetermined test data set. The traversal numbers of the expanded directed graph are balanced to form a symmetric expanded directed graph. An Euler tour and a corresponding unique input-output sequence of the last state of the Euler tour are generated to form the conformance test data sequence. The generated conformance test data sequence exhaustively tests the values in the test data set, and achieves an efficiency in conformance testing by minimizing the amount of time required to perform the conformance test.

Title: Process for the production of dinitrotoluene
Inventor: KLINGLER UWE
IPC: C07C205/06
Filed: 1995-08-07
Abstract: Dinitrotoluene is produced by nitrating toluene with nitrating acid under adiabatic conditions in a manner such that some mononitrotoluene is present in reaction mixture. The nitration reaction mixture is then treated to remove at least 5% by weight of water before the reaction mixture is separated into an acid phase and an organic phase.
