Abstract: A biopsy probe is provided for the collection of at least one soft tissue sample from a surgical patient. The probe comprises a frame having distal and proximal ends. The probe further comprises an elongated piercing element attached to the distal end of the frame. The piercing element has a sharpened distal end for piercing tissue, and a port located proximal to the sharpened distal end for receiving a portion of tissue mass positioned adjacent to the port. The probe further includes an elongated cutter having proximal and distal ends. The cutter is disposed coaxially and slideably relative to the piercing element and has a cutting blade on the distal end for cutting the portion of tissue protruding into the port of the piercing element' when the cutter slides distally past the port, thereby depositing the portion of cut tissue within the cutter lumen of the cutter proximal to the cutting blade. In one embodiment, the probe further includes a tissue remover disposed in the cutter lumen of the cutter and having a structure on the distal end for obstructing the cutter lumen so that a tissue sample protruding into the port and severed by the cutter is prevented from moving proximally through the cutter lumen. In another embodiment, the probe further comprises a distal frame seal, a proximal frame seal, and a proximal cutter seal for substantially preventing the passage of fluids through a first, a second, and a third radial space, respectively, within the probe. In a preferred embodiment, a valve is provided on the proximal end of the tissue remover for the releaseable attachment to a reservoir.

Patent CA-2284310-A1 (CA)
Title: Programmable network element for packet-switched computer network
Inventor: COHEN ARIEL
IPC: H04L12/56
Filed: 1999-09-29
Abstract: A programmable network element (400) operates on packet traffic flowing through the element in accordance with a gateway program (404, 405, 406) which is dynamically uploaded into the network element or unloaded from it via a mechanism separate from the actual packet traffic as the element operates.  Such programmable network element can simultaneously operate on plural packet flows with different or the same programs being applied to each flow. A dispatcher (402) provides a packet filter (403) with a set of rules provided by one or more of the dynamically loaded and invoked programs. These rules define, for each program, the characteristics of those packets flowing through the network element that are to be operated upon in some manner. A packet that flows from the network through the filter and satisfies one or more of such rules is sent by the packet filter to the dispatcher. The dispatcher, in accordance with one of the programs, either sends the packet to the program for manipulation by the program itself, or manipulates the packet itself in a manner instructed by the program. The processed packet is sent back through the filter to the network for routing to its destination.
Patent CA-2284684-A1 (CA)
Title: Cnc machine having interactive control of corner tolerance
Inventor: DE CAUSSIN GLENN F
IPC: G05B19/4093
Filed: 1998-03-18
Abstract: A CNC machine is programmed to redefine the corner tolerance as a function of the corner angle based on a recognition that corners having angles not equal to 90~ have effective corner tolerances that are equal to the corner tolerance specified by the operator divided by the sine of the corner angle. An increase in machining speed is achieved, because, at corner angles not equal to 90~, the redefined corner tolerance is larger than the operator-specified corner tolerance and the CNC machine is permitted to machine the corner at an earlier time than conventional CNC machines. The CNC machine is also programmed to provide the operator with an interactive control of the parameters that control the speed and accuracy of machining. With this feature, the operator is able to observe the effects of changing the control parameters on the speed and accuracy of machining, and to customize the control parameters to a particular type of tool or application based on the observations.

Title: A process for producing liquid and, optionally, gaseous products from gaseous reactants
Inventor: SILVERMAN ROY W
IPC: C07C/
Filed: 1998-07-14
Abstract: A process for producing liquid and/or gaseous products from gaseous reactants comprises feeding (14) them, at a low level, into a slurry bed (40) of particles suspended in a liquid, to react as they rise therethrough to form the products, the reactants and any gaseous product assisting in maintaining the suspension. The liquid product forms, together with the suspension liquid, the liquid phase of the bed. Any gaseous product and unreacted reactants rise from the bed into a head space (44). Slurry passes downwardly in the bed through downcomers (22, 32) located respectively in first and second downcomer regions {20, 30) of the bed, thereby redistributing solid particles within the bed. The second downcomer region is spaced vertically with respect to the first downcomer region. Any gaseous product and unreacted reactants are withdrawn (16) from the head space (44) and liquid phase is withdrawn (18) from the bed. Preferably a Fischer-Tropsch synthesis takes place with the gaseous reactants being in the form of a synthesis gas stream comprising mainly carbon monoxide and hydrogen.
