Title: Protective liner system and method for installing same
Inventor: SMITH KENNETH GERALD
IPC: B60R13/01
Filed: 1992-12-22
Granted: 1996-12-03
Abstract: A protective liner system and method for installing the same on a structure such as a dump truck hopper are disclosed.          The protective liner system comprises a plurality of  sheet members securely fastened to the otherwise exposed surface of the structure.  The edges of adjacent sheet members are joined by an overlapping sliding joint wherein the sheet members are in first-edge to second-edge facing relation such that the first-edge of one sheet member is spacially opposed the second-edge of a second sheet member so as to form a gap therebetween.  A first spanning member contacts the first faces of the sheet members and is securely  fastened  to  the metal  structure  so  as  to  be in intimately contacting sliding relation to the first faces of the sheet members.   The sheets are also placed in first-end to second-end juxtaposed relation such that a downwardly sloped portion of the first-end of one sheet functionally contacts a second-end on the first face of the other sheet, so as to create a joint that is substantially flush at its top face.   The protective  liner  system thus  configured allows  for  lateral expansion of the sheet members so as to preclude buckling of the sheet members during expansion and loss of sealant placed between adjacent ends of the sheet members.

Title: Method and apparatus for training a neural network
Inventor: WOOD DAVID CHARLES
IPC: G06N3/08
Filed: 1991-11-08
Granted: 1999-02-16
Abstract: A method of training a neural network (2) having dynamically adjustable parameters controlled by a controller (10) which determine the response of the network (2). A set of input vectors (I l to I n) are input to network (2) at an input port (4). The corresponding set of output vectors (O'l to O'n) provided by the network (2) are compared to a target set of output vectors (O l to O n) by an error logger (12) which provides to the controller (10) a measure of similarity of the two sets. The controller (10) is arranged to alter the dynamic parameters independence on the average number of occasions the output vectors are different from the respective target output vectors. Measuring the similarity of the whole of the output set and target set and adjusting the parameters on this global measure rather than on the similarity of pairs of individual vectors provides enhanced training rates for neural networks having a data throughput rate that can be higher than the rate at which the parameters can be adjusted.

Title: Automatic on-line monitoring and optimization of optical network switching nodes
Inventor: FATEHI MOHAMMAD T
IPC: H04B10/29
Filed: 1993-06-18
Granted: 1997-03-18
Abstract: An on-line technique which allows the monitoring and adjustment of switching node control parameters within an optical network. More specifically, a technique wherein a low-frequency modulation is induced upon an optical signal as it passes through a node within a switch or sub-system by varying the control voltage applied to that node about what is assumed to be the optimum control voltage level, the optical signal at position downstream from the node is analyzed to ascertain the amplitude, frequency, and phase characteristics of the induced low-frequency modulation, and a determination is made, on the basis of the amplitude, frequency, and phase information, as to the whether the control voltage which was assumed to be optimal is indeed at the correct level to insure proper operation of the node. The amplitude of the induced low-frequency modulation may be maintained at low level so as not to interfere with the transmission of the primary information and data carried by the optical signal. Analysis of the amplitude, frequency, and phase of the modulated signal may be performed at a single fixed location within the network. Furthermore, multiple switching nodes may be monitored simultaneously from a single location within the network by modulating each node at a unique frequency. This allows each modulated signal received to be differentiated from all others, and readily identified as having originated at a particular node.

Title: Differential gear
Inventor: MIMURA KENJI
IPC: F16H48/12
Filed: 1995-03-03
Granted: 1998-05-26
Abstract: A   small,   inexpensive,   comparatively   simple differential  gear,  having  reliable  revolution  difference restricting effects includes a rotary casing and a retainer having a common rotation axis.  Torque is transmitted to a groove of a pair of rotary members via rolling elements so the rotary members rotate with the casing. When a revolution difference occurs between the rotary members, rolling elements retained in guide slots of the retainer roll along the grooves of the rotary members so there is reciprocal movement within the  range of the guide slots.   When a  force causing a revolution difference between the rotary members is applied from the   side of only one of the rotary members,  the resulting reaction force restricts the revolution difference between the pair of rotary members.   This is because the rolling elements which come to the following side when the revolution difference exists trail the groove which comes to the  leading side when a revolution difference occurs in response to their own movements. Reliable torque-sensitive revolution difference restricting effects are provided without a  special  mechanism  to  obtain  a  revolution  difference restricting effect.

Granted: 2000-05-09
Abstract: The present invention relates to a paint roller capable of applying paint to inner corners, edges, and along or adjacent straight lines while still being appropriate for large area surface painting. The roller has an angled end face which spaces the end away from adjacent surfaces, while the contact surface of the roller applying paint can reach up to the inner corner. The construction includes an axle having a straight portion and an angled portion attached to one end by a fixed offset link. The straight portion carries a cylindrical roller body, while the angled portion carries a frusto-conical roller body of a size to extend the substantially linear contact surface of the cylindrical roller. The cylindrical roller has an open end partially containing the frusto-conical roller.      Both roller bodies are encased by a tubular covering having pile fibres for carrying paint. The covering is elastic at least in the direction parallel to the straight portion of the axle. Therefore, as the frusto-conical roller rotates it will displace the tubular covering in the longitudinal direction. A handle is provided on the straight portion of the axle having an angular locking means for adjustment.
