Granted: 1999-06-22
Abstract: The initial stages in the manufacture of a glass-like mineral fiber suitable for a multiplicity of industrial uses are essentially conventional; a charge of raw minerals (igneous rock, basalt, slag from a blast furnace or other metal working furnace, phosphate slag, etc.) is melted, then spun and collected to produce a fibrous mineral "blanket".          The "blanket" is chopped up, separated, and screened, producing a prilled material constituting a multiplicity of mineral fiber pellets of given average size.  These pellets are subjected to brief, rapid acceleration, as by contact with a high-speed toothed rotary wheel, to accelerate and stress the pellets into an industrially usable material constituting a multiplicity of shredded, flake-like mineral fiber elements, at least one such element for each pellet.

Title: Pattern recognition with a tree structure used for reference pattern feature vectors or for hmm
Inventor: WATANABE TAKAO
IPC: G10L15/32
Filed: 1994-06-01
Granted: 1999-09-14
Abstract: Preferably using frame vectors, a reference memory (13) keeps feature vectors of a set as a tree comprising a root node, leaf nodes farthest from the root node, and intermediate nodes with the frame vectors assigned respectively to the leaf nodes. A calculator (17) calculates cluster distances between each feature vector of an input pattern and a subset assigned among the set to each daughter node of a mother node which is first the root node. From the intermediate nodes with the mother node successively selected along each branch of the tree, a selector (19) selects at least one daughter node that gives a shortest possible cluster distance. Controlling the calculator and the selector to use the cluster distances starting at each node selected nearest to the root node and proceeding along the branches to one of the leaf nodes that are used as daughter nodes of mother nodes selected nearest to the leaf nodes, a pattern distance calculator (15, 23) calculates pattern distances between the input pattern and reference patterns represented by the set. If the branches do not reach such leaf nodes, the cluster distances are used to the mother node last selected.      Frame distributions of HMM may be used instead of the frame vectors.

Patent CA-2128086-C (CA)
Inventor: SHELBOURNE KEITH HOWARD
IPC: A01D75/18
Filed: 1993-01-12
Granted: 2002-09-24
Abstract: A crop stripper has at least one drum (6a, 6b) with several axially extending series of stripping teeth (8). The drum is rotat-ably in end supports. The tooth roots (26) at the ends of the drum have an edge profile inclined radially away from the adjacent supports to deflect plant stems which contact these profiles during the operation of the stripper away from the supports, so redu-cing the tendency for the stems to become trapped between rotor and support. A  capping (32) on the support overlaps the adja-cent tooth roots to assist this effect. A pair of drums can be arranged end to end with an intermediate support (14) between them and be similarly arranged to deflect plant stems away from the intermediate support. This allows increase of the operating width of the crop stripper while minimizing the risk of blockage from stems trapped between the intermediate support and the drums.

Title: Method and apparatus for transporting plastics in a melted state
Inventor: SCHWOCHERT HANS
IPC: B29C49/04
Filed: 1994-11-10
Granted: 1999-07-20
Abstract: A method and apparatus is provided to transport parisons from the extrusion die to a second location. The parison is extruded and a collar means is provided to contact the parison near its upper end and create a holding geometry whereby the parison is retained by the collar means without pinching the parison. The parison is then transported vertically or horizontally to the mold unit without closing or pinching the parison. The holding geometry is created by slightly deforming the parison wall near the collar means. The parison is therefore transported to the second location, for example a mold unit, instead of moving the mold unit, to the parison.

Abstract: An improved, elongate, flexible corner for trimming a curved surface, such as a cylindrical surface of a building column, comprises an elongate angle extruded from a relatively hard but flexible, polymeric material and an elongate strip extruded from a relatively soft but pliable, polymeric material.  The elongated angle and the elongate strip are coextruded respectively from polyvinyl chloride having different durometer hardnessess.  The elongate angle has a first, relatively wide, relatively thick flange with a distal edge and a proximal edge and a second, relatively narrow, relatively thin flange with a distal edge and a proximal edge, which is unitary with the proximal edge of the first flange. The second flange extends from the first flange, approximately at a right angle relative to the first flange when the flexible corner is unstressed.  Each of the first and second flanges has an inner surface and an outer surface and the inner surfaces define approximately a right angle relative to each other.  The elongate strip is attached to the elongate angle, along the flexible corner.  The elongate strip is configured so as to have a proximal portion covering the outer surface of the second flange, as far as the outer wall of the first flange, and a distal portion extending beyond the distal edge of the second flange, approximately at a right angle relative to the first flange when the flexible corner is unstressed, and so as to have a recess receiving the second flange.
