Patent CA-2192325-A1 (CA)
Title: Washer for use in mining
Inventor: FERGUSSON JEFFREY ROBERT
IPC: E21D21/00
Filed: 1995-06-09
Abstract: The washer is of frusto-conical shape as viewed externally and consits of a body (21) and a tapered flange (23) depending therefrom. When the lip (28) of the flange rests on a flat surface and the washer is subjected to a predetermined compressive load (26) the tapering of the flange leads to its deformation radially outward. This expansion acts as a visual indication that the predetermined load has been applied. The flattening of the flange which also accompanies its deformation increases the contact area of the washer with the underlying surface and thereby reduces contact stresses. When used in rockbolting, hole (22) receives a rock bolt and the void defined by the flange (23) can accommodate a raised portion of a load plate. The recess (30) receives a bearing assembly or a domed element (the latter compensates for misalignment of the bolt with the surface) so as to transmit tightening loads from the nut of the rock bolt to the washer, etc.

Title: Method of Producing Tooth Flank Surface Modifications
Inventor: STADTFELD HERMANN J
IPC: B23F19/00
Filed: 1995-09-15
Abstract: A method of producing flank surface modifications in gear teeth by controlled removal of stock material from a work gear with a tool. The method comprises providing a gear producing machine with the tool (42) and work gear (50) being movable with respect to one another along and or about a plurality of axes. A  theoretical basic machine is provided comprising a plurality of machine settings for relatively positioning and moving a tool (24) and work gear (26) with respect to one another. Each of the machine settings is defined as an active setting with each active setting being represented by a function. A  desired tooth flank surface modification is determined and defined by a set of coefficients for each of the active settings. The function for each active setting is then determined based upon the respective coefficents for each active setting and the functions are transformed from the theoretical machine to the axes arrangement of the gear producing machine. By this transformation, active settings movement defined on the theoretical machine is carried out on one or more of the axes of the gear producing machine to remove stock material from the work gear (50) with the tool (42) in accordance with the active setting functions of the basic machine.

Patent CA-2214208-A1 (CA)
Title: Latch for a wire gate
Inventor: SROKA SHANE WALTER
IPC: E05B65/00
Filed: 1997-08-27
Abstract: A latch for a wire gate includes a frame defining a post confining enclosure.  The frame is clamped to a fixed fence post in a substantially horizontal orientation.  One of the sides of the frame is pivots about a substantially   vertical axis.   A spring biases the pivotally mounted side toward a closed position against the frame.  A guide channel is provided for directing a movable fence post between the pivotally mounted side and the frame.  The latch, as described above, enables a person to close a gate with one hand by pushing a movable fence post into the guide channel.  As the post passes along the guide channel, the biasing force of the spring is overcome sufficiently to move the pivotally mounted side to an open position and allow entry of the post  into the post confining enclosure.

Abstract: A running/setting tool for packers is disclosed which can release in several different ways. The tool can be pumped through for normal release. The tool may be hydraulically released by dropping and pumping a ball to a seat and subsequent pressurizing. A frangible member is provided so that if circulation is impeded, it can be established by breaking the frangible member to allow a ball to be pumped to a seat. Finally, a shear release technique is provided which allows release by breaking a shear pin or shear ring or other frangible member, which unsupports collets to allow for removal. A support shoulder is provided on the tool to prevent the collets from becoming stressed on the trip out of the hole if the tool encounters a collar or other internal obstruction.

Title: Air abrasive particle apparatus
Inventor: BRUNS CRAIG R
IPC: B24C7/00
Filed: 1996-05-09
Abstract: This invention is a method and apparatus for an air abrasive unit such as those used in the dental field. This method and apparatus utilizes an internal vibrator motor (32) with vibration transmitters (33) which transmit the vibration throughout the abrasive jar (11). The abrasive pickup assembly uses pressure differentials to suck up abrasive (16) through a screen (30) which controls the flow rate and particle size of the abrasive flowing through the system. The system can utilize a photo-optical detection system to detect the abrasive level. Alternatively, a pressure/pulse detection system may be used to measure abrasive level. Dilution of the air/abrasive mixture and "air only" modes are possible with the present system. De-pressurization and mere reductions of pressure can also be accommodated. The invention also includes a system for easily modifying the content of an air abrasive stream exiting the mixing chamber.

Abstract: La table de voies logiques (LCT) dans laquelle des voies classiques ou composites sont utilisées, permet le mappage entre un numéro de voie logique (LCN) représentant un service et le numéro de courant de transport TSID)/numéro de programme (PN) auquel on peut trouver le service. L'entrée de la table de voies logiques contient un indicateur de voies composites qui, lorsqu'il est sur 1 indique que la voie sélectionnée est une voie composite et indique ainsi la voie locale de la voie composite. La LCT fournit la table de voies composites (CCT) au décodeur (10) de sorte que le syntonisateur (12) puisse être renvoyé au programme réel désigné dans la CCT pour une visualisation en cours. Chaque entrée dans la CCT associe un numéro de voie composite (CCN) à un LCN et représente la définition présente pour la voie composite. Dans le temps, le CCN est utilisé comme indicateur pour le LCN qui est le service actif en cours pour la voie composite. Ces tables fonctionnent avec des définitions MPEG-2 standard pour décoder les courants de transport multi-service.
