Title: Cardholders incorporating keepers
Inventor: GODFREY RICHARD LAWRENCE
IPC: B42D107/00
Filed: 1990-07-19
Granted: 1996-01-02
Abstract: In the technical field of known cardholders for devices such as cards with magnetic stripes on which is encoded informa-tion and/or data in the form of patterns of magnetism, the known cardholders offer no method of 'keeping' (in magnetism ter-minology) the magnetic patterns. The present invention is characterised by incorporating into the cardholders, keepers (1) in the form of sheets of magnetically soft ferromagnetic material with high resistance. The benefit of the invention is obtained when de-vices are placed with the reading surface of their magnetized stripes in close contact with the surface of the ferromagnetic materi-al which, making use of known properties of the material, then acts as keeper of the magnetic patterns.

Granted: 1997-01-14
Abstract: A method and apparatus is provided for encoding and decoding. In encoding, bits (202) are encoded (204) into symbols (206) such that maximum likelihood decoding is facilitated. Groups of symbols (206) are translated by either interleaving by group each group within a block (208) and subsequently deriving an orthogonal code from each group (212) or deriving an orthogonal code from each group and subsequently interleaving by code each code within a block.  In decoding, groups of samples (228, 229) are transformed by either generating metrics and index symbols (242) for each group of samples (232, 234, 236, 238, 240) and subsequently deinterleaving by group each group of metrics within a block (244) or deinterleaving by group each group of samples within a block and subsequently generating metrics and index symbols for each deinterleaved group of samples. Each metric represents the confidence that a group of samples is a particular orthogonal code. Subsequently, maximum likelihood decoding (266) generates an estimated bit (268) from the index symbols and metrics (260).

Abstract: A continuous process for the manufacture of strong discontinuous fibres from a polyolefin is disclosed. The process comprises feeding a solution of polyolefin dissolved in an organic solvent at a pressure that is at least autogenous pressure to a spinneret.      Plexifilamentary film-fibril strands are formed by flash spinning, by passing said solution through the exit of the spinneret and into a tunnel at a lower pressure and temperature than the solution, the temperature being greater than the boiling point of the organic solvent.      At or subsequent to the exit from the spinneret but inside the tunnel, the strands and solvent are contacted in the tunnel with an inert fluid that has a liquid and a vapour phase, the amount of inert fluid being such that the ratio of the total volumetric flow rate of solvent vapour plus inert fluid vapour to the mass flow rate of the polymer is greater than 4.5 m3/kg in the tunnel. The temperature of the inert fluid in the tunnel is 2-40°C lower than the melting point of the polymer. Strong discontinuous fibres are recovered. The fibres, especially in the form of a pulp, may be used as part of thermally bonded blends with cellulose, as a filler and in the form of sheet.

Title: Systems and processes for pyrolyzing contaminates on foundry sand and combusting the resulting gas
Inventor: BURY ROLAND P A G
IPC: F23G5/00
Filed: 1994-10-28
Granted: 1998-09-29
Abstract: The invention relates to combusting contaminants on foundry sand in a container (13) rotating about an axis (A) at a particular angle with a particularly placed oxygen-fuel burner (32).  As the container (13) rotates about the axis (A), the oxygen-fuel burner (32) fires a flame and excess oxygen at a particular angle to enhance pyrolysis of the contaminants.  The amount of excess oxygen is such that the resulting off gas contains at least 2% oxygen by volume, thus preventing or substantially minimizing products of incomplete combustion from leaving the container (13).  After having pyrolyzed the contaminants, the firing of a flame and excess oxygen from the oxygen-fuel burner (32) may be replaced with oxidant dispersion at the bottom of the foundry sand. The resulting off gas from the container (13) may be treated in a post combustion furnace (7), a flue gas cooling means (8), a filtering device (9) and/or a pollutant removing means (11).

Patent CA-2138503-C (CA)
Inventor: TAPPER ULF ANDERS STAFFAN
IPC: G01N23/05
Filed: 1994-12-19
Granted: 2004-10-12
Abstract: Particles are classified according to the presence or absence in the particles of a particular substance. In one example, kimberlite particles (16) are analysed for the presence of diamond (36). In the method, each particle (16) is irradiated with a beam (20) of fast neutrons at a resonant energy level for the particular substance. For each particle an image is derived which is representative of transmission of the beam by the particle. The particles are then classified according to whether or not the derived image is indicative of the presence in the particle of the particular substance. The method can be enhanced by irradiating the particles with neutron beams at resonant and non-resonant energy levels, and a resultant image is derived from the transmission spectra at both energy levels. The classification is then made from an analysis of the resultant image.
