Title: Procede de blanchiment d'une poudre vegetale micronisee
Inventor: DEVIC MICHEL
IPC: D21C9/16
Filed: 1995-12-28
Abstract: La  présente  invention  concerne  un  procédé  de blanchiment d'une matière végétale, sous forme d'une poudre micronisée, par le peroxyde d'hydrogène en présence d'une base.   Dans ce procédé,  on imprègne une poudre végétale micronisée par deux solutions distinctes A et B de façon à ce que les deux solutions soient totalement absorbées par la poudre qui reste ainsi à l'état de poudre solide, A étant constituée par une solution aqueuse de peroxyde d'hydrogène, B étant constituée par une solution aqueuse basique contenant un agent alcalin.  Ce procédé présente notamment l'avantage d'être  particulièrement  adapté  pour  traiter  des  poudres végétales micronisées à des coûts relativement faibles.
Patent CA-2167101-A1 (CA)
Title: Long-timber chipping machine
Inventor: SCHAFER KARL
IPC: B27L11/02
Filed: 1996-01-12
Abstract: Along-timber chipping machine has a timber feed channel for receiving longitudinally arranged timbers, advanced using a timber-advancing device to a vertically movable chipping device positioned at the downstream end of the feed channel. The chipping device has a rotatable cutter ring equipped with chipping cutters on its cylindrical inner wall, which defines a chipping chamber. The chamber is aligned with the downstream end of the feed channel. To improve the chipping, a curved timber-receiving plate projects into the chipping chamber from the downstream end of the feed channel, which also has a matching curved base. The curvature of the plate and the base match the curvature of upper cylindricalinner wall of the cutter ring so that the upper cylindrical inner wall can be lowered closely to the plate, leaving only a very small clearance and exposing all of the timbers to the chipping cutters. To better guide the timbers into the chipping chamber, the chipping device includes two vertical side walls attached to the housing that shields the chipper ring. These side walls extend into the chippingchamber and spaced apart so that the plate is positioned between the side walls and allow the side walls to move as the chipping device is vertically displaced.

Ce perfectionnement a l'avantage de permettre un passage à la catégorie de certification immédiatement inférieure sans nécessiter l'emport d'une plateforme inertielle qui est un dispositif coûteux à la fois à l'achat et à la maintenance.
Patent CA-2170252-A1 (CA)
Title: Twisting apparatus
Inventor: PHILLIPS DAVID GRAHAM
IPC: D02G1/08
Filed: 1994-09-15
Abstract: Apparatus for twisting a traveling strand includes a rotary structure rotatable about a rotational axis X--X and a series of pulleys mounted on the structure in an array disposed about the rotational axis X--X with each pulley in the series mounted on the structure for rotation about an individual axis of pulley rotation which is generally parallel to the axis X--X and moves around that axis on rotation of the structure. An input strand guide pulley guides an input strand to be twisted onto a path in which it will successively engage the pulleys and a strand exit guide pulley guides the strand from that path into an exit path along the axis X--X. The rotary structure is driven through a drive shaft and the pulleys are rotated by gearing.

Title: Cap Assembly
Inventor: ELLETT JAMES RICHARD
IPC: H01H13/14
Filed: 1996-06-06
Abstract: A cap assembly for a device operated by a button switch, in which the cap assembly includes a housing having a device side and an exterior side. The device side includes threads for attaching the housing to  the device. The  housing has  an  interior bore extending from the device side to the exterior side.

The telescoping spring loaded plunger has  an exterior  cap on the  exterior side of  the housing, an interior cap on the device side of the housing and an interior spring resisting longitudinal movement of  the  interior  cap  in  relation  to  the exterior   cap. The   interior   cap   has   limited longitudinal travel in relation to the plunger. A stop on the device side limits longitudinal movement of the plunger towards the exterior side.  A stop on the exterior side to limit longitudinal movement of the plunger towards the device side. The interior spring has a force constant such that force acting on the button switch through the spring is sufficient to trip the button  switch but  insufficient to damage the button switch. The degree of longitudinal travel of the  interior  cap  is  selected  such  that when  the exterior cap has reached the limit of its longitudinal travel towards the housing, the interior cap has not penetrated so far towards the device to damage the device.

Abstract: A dental implant is provided that can be firmly fixed in an oral cavity, even if the amount of bone required to embed the implant is small. A necessary amount of bone can be provided by generating new bone so that the fixture part of the implant can be fixed in the bone. The fixture part of the implant includes several members which are movably connected to each other so that the fixture part is adjustable in length. The fixture part includes a first member which is made up of an uppermost member, a middle member, and an end member. It is preferred that the middle member be cylindrical or rod-shaped with male screws extending radially-outwardly from an outer circumferential periphery thereof. The fixture part also includes a second member which is a hollow cylinder. It is preferred that the hollow cylinder have a tapped hole on one end with female screw on an inner periphery thereof so that the middle member of the first member can be screwed into the second member. A continuous stimulating force which is formed by the embedment of the implant into bone and the lifting up of the mucous membrane by extending the fixture part of the implant, contributes to the osteogenesis around the implant

Inventor: FRANK STEPHEN JEFFREY
IPC: F42B10/06
Filed: 1996-10-08
Abstract: It is known to use a rigid cone to provide stability to a body being towed by an aircraft. However, such cones are useful over a limited range of speeds.  The invention provides a drag-producing aerodynamic device in which the cross-sectional area of the structure producing drag is variable.  The cross-sectional area of the structure producing drag decreases as the towing speed, and hence the dynamic air pressure acting on the structure producing drag, increases and vice versa.

Inventor: VAN WYK ROBERT A
IPC: A61B17/32
Filed: 1997-04-10
Abstract: A process for simultaneously shaping and sharpening a cutting widow at the distal end of a tubular member of a rotary blade assembly. The assembly is provided with a stationary. elongated outer tube, having a cutting window at its distal tip and includes a rotatable elongated inner tube having a cutting means at its distal tip. The window in the outer tube has a curvilinear profile defined by a peripheral rim surrounded entirely by a land surface which is inclined relative to the rim.      The inclination of the land produces an area which tapers from a full thickness, where the land is adjacent to the cylindrical wall of the outer tube, to a sharp edge around the periphery of the window. The curvilinear window is produced by a manufacturing process which creates the window opening with a sharpened periphery at the same time that the land surrounding the opening is inclined. A preferred embodiment utilizes electrochemical grinding of the distal ends of the tubular member by a tool having a rotatable wheel with a perimeter in the shape of a groove of predetermined arcuate profile.
