Patent CA-2124775-A1 (CA)
Title: Junk separator for, and in combination with, a pulp slurry inlet chamber of a pulp handling machine
Inventor: YOUNG DOUGLAS L G
IPC: B01D21/26
Filed: 1994-05-31
Abstract: Abstract of the Disclosure In the floor of a pulp slurry inlet chamber an opening is provided.   The opening is elongate and arranged substantially tangential to the outer, bounding wall of the chamber.  Barriers of arcuate cross-section depend from the opening, at opposite ends of the opening.  The barriers are incurvate, relative to the opening.          The  opening  has  a  length  which  junk  cannot  bridge  across.          Consequently, the junk falls through the opening and is captured in an accumulator which underlies the opening.  Knots substantially bridge across the opening, and impinge upon the arcuate barrier at the far end of the  opening to be thrown upwardly for assimilation with the slurry flow coursing through the chamber.  An elutriative liquid is supplied to the accumulator, at a given flow velocity, to wash up and out of the accumulator any organic particles which, due to irregularities, pass through the opening, to return the organic particles to the chamber.

IPC: B29C48/12
Filed: 1995-03-27
Abstract: The present invention relates to a process for manufacturing frame members for picture frames and to the product of that process. The process comprises the steps of forming a plastics extrusion and cutting it into lengths and applying to the lengths of plastic extrusion a solvent based wood paste which is then moulded or otherwise shaped such that it forms ornamentation on the surface of the plastics extrusion and it is then allowed to dry. This process makes use of the low cost of extrusion plastics moulding but enables the ornamental features that would otherwise only be obtainable by injection moulding to be obtained with the extrusion moulding.

Title: Bicycle; chain strain sensing sprocket mechanism
Inventor: NEARY JOHN R
IPC: B62K23/00
Filed: 1995-04-04
Abstract: A simple automatic operating device intended to improve the operation of power assisted bicycles.  The device consists of a small free turning sprocket (chain strain sensing) mounted near one end of a short moveable arm.  The other end of the moveable arm pivots on a frame mounted bracket attached to the bicycle frame mid-way between the crank arm sprocket and the rear wheel sprocket.  A spring holds the arm up, which holds the attached sprocket against the underside of the upper length of a slightly long bicycle drive chain.  Pedal force, in excess of that required to ride on the level, increases the chain tension, forcing the sensing sprocket and arm downward.  In one application of the device, movement of the arm can be used to operate a three range variable resistor to automatically control current flow to and from an electric motor-generator of a power assisted bicycle.  In a second application, downward movement of the chain strain sensing sprocket arm can be used to automatically control the throttle mechanism of an internal combustion bicycle engine used for power assist.

Title: Traffic management and congestion control for packet-based networks
Inventor: HANSON RAYMOND H
IPC: H04L12/56
Filed: 1995-12-05
Abstract: In a packet-based communications network (100), a virtual connection is established between a source node (102a) and a destination node (102b), which may traverse one or more intermediate nodes (105).  During the flow of packets along the virtual connection in a forward direction, from the source node (102a) to the destination node (102b), each node measures the utilization of critical resources (CUF), and this utilization information is inserted into return packets flowing in the backward (return) direction, from the destination node (102b) to the source node (102b).  CUF is indicative of the maximum utilization of any resource in the virtual connection forward path.  If the network utilization information indicates that the resources of a virtual connection are under-utilized, the submission rate (SIR) of packets onto the virtual connection is increased. However, if the network utilization information indicates that the resources of the virtual connection are over-utilized, the submission rate of packets onto the network at the source node is reduced.
