Title: Pivoting table with power tool
Inventor: GARUGLIERI ANDREA
IPC: B23Q1/54
Filed: 1993-08-16
Abstract: ABSTRACT                        PIVOTING TABLE WITH POWER TOOL       A table (16) is pivotable about an axis (41) with respect to a frame (14) between two working dispositions. A power tool working assembly (20) may be mounted on the table. A working head (eg blade 32) of the assembly (20) is positionable through an aperture in the table so that it can work on workpieces supported above either side of the table.      The table is connected to the frame through an intermediate member (46) which is pivoted to the frame. The table has a first wheel (40) fixed thereto and a belt passes around the first wheel and around a second wheel (50) fixed to the frame (14) around the pivot (51) of the intermediate member. Pivoting of the intermediate member relative to the frame rolls the first wheel inside the belt and rotates the table between bench mode (Figure 2) and snip-off mode (Figure 3).

Patent CA-2106410-A1 (CA)
Title: Ablation electrode with insulated temperature sensing elements
Inventor: EDWARDS STUART D
IPC: A61B19/00
Filed: 1992-11-05
Abstract: An ablation electrode (16) carries a temperature sensing element (94) for measuring the temperature of the tissue being ablated. A thermal insulating element (88) associated with the sensing element blocks the transfer of heat energy from between the temperature sensing element (94) and the electrode (16), The temperature sensing element therefore measures temperature without being affected by the surrounding thermal mass of the electrode (16).

Patent CA-2114271-A1 (CA)
Title: Spinel-carbon refractory
Inventor: KNAUSS RICHARD J
IPC: C04B35/52
Filed: 1994-01-26
Abstract: SPINEL-CARBON REFRACTORY          ABSTRACT OF THE INVENTION      The problems associated with the low thermal shock resistance of conventional refractories utilized in continuous casting operations are overcome by a spinel-carbon refractory which provides improved thermal shock resistance.  The spinel-carbon refractory of the present invention includes either a sintered spinel, a fused spinel, or a mixture of sintered and fused spinel in combination with a source of carbon, such as flake graphite.  Spinel (magnesium aluminate, Mgo.A12O4) imparts into the resultant refractory a lower overall thermal expansion which improves the thermal shock resistance of the shape.  Minor additions of alumina, magnesite, zirconia or combinations of these materials can be added to the spinel based mix of the present invention without significantly compromising-the overall decrease in thermal expansion of the base mix.  Additionally, metallic additions, such as aluminum, silicon, magnesium, or various alloy mixtures can be added to the base mix to enhance oxidation resistance and hot strength.  It is believed that magnesia-enriched spinel, stoichiometric spinel (72 wt.          % alumina and 28 wt. % magnesia), and alumina rich spinel can be used with equal or near equal results.          The spinel grain used in the spinel-carbon refractory of the present invention should be free of impurities, that is, it should contain less than 1 wt. % lime and less than 2 wt. % silica.

The morcellator is adapted to be inserted through a laparoscopic port site and directly fragment and aspirate tissue from within a patient's body.      Alternate  embodiments  of  the  present  invention  provide different cutting head extension and retraction devices.  The morcellator of the present invention allows removal of tissue without the need for large entry incisions.

Title: Remote file transfer method and apparatus
Inventor: PYNE CHARLES F
IPC: H04L29/08
Filed: 1995-01-12
Abstract: Remote file transfer applications often involve a situation where a receiving computer (22) contains a reference file (48) that may be similar, or perhaps even identical to, a source file (46) to be transmitted by a sending computer (20). Disclosed is a file transfer method that identifies and isolates the differences between the two files, and transmits only those differences to the receiving computer.  The method divides the data in the reference file into a plurality of blocks and associates each block of data with a key value. The key values are then sent to the sending computer in the form of an array. At the sending computer, a block of data at the source file is identified, its key value computed, and the key value is then compared to the keys in the array. If a match is found, an indication of such is sent to the receiving computer. Otherwise, a byte of data from the data block is sent to the receiving computer. and a subsequent block of data is identified and analyzed. The latter steps of the method are repeated until a representation of the source file is present at the receiving computer.
