Patent CA-2129917-A1 (CA)
Inventor: MCKEIGUE KEVIN
IPC: B01D3/26
Filed: 1994-08-11
Abstract: A distillation  column for separating atmospheric gases in which structured packing having varying crimp angles is utilized within at least two sections or subsections of a single section of a distillation column. In the case of the use of structured packing in multiple sections, the crimp angle of the structured packing used in the first section is greater than that of the second section and is selected such that both sections operate at the same maximum design percentage of flooding limit.  The increased crimp angle of the first section decreases  the HETP of the packing and thereby allows a column design of reduced height.  Structured packing having different crimp angles can be used in a single section of a column when such section is subjected to possible variation of vapor rate. Here the crimp angles are again manipulated so that the subsections operate at the same maximum design  percentage  of flooding  limit.   The foregoing adaptation improves turndown performance.

Patent CA-2134090-A1 (CA)
Inventor: JOHNSON LIANN M
IPC: A61F2/82
Filed: 1993-03-10
Abstract: A radially self-expanding stent (90) particularly suited for treating esophageal strictures, includes a medial region (92) and proximal and distal cuffs (94, 96) having diameters greater than the medial region (92) diameter when the stent (90) is in the re-laxed state.  A silicone coating circumscribes the medial region (92), but the cuffs (94, 96) are not coated and retain their open weave construction.  As a result, the cuffs (94, 96) remain particularly well suited to immediately contact esophageal wall tissue and resist stent migration, while the silicone coated medial region (92) provides a barrier to tumor ingrowth, and has an enhanced radial restoring force to maintain an open passageway in the esophagus.  A deployment device (16) for the stent (90) includes an interior catheter (26) surrounded by the stent (90) and having an esophageal dilation feature (28), along with an exterior catheter (18) that radially compresses the stent (90).  A low durometer sleeve (54), fixed to the interior tube (26) and in surface engagement with the compressed stent (90), tends to fix the axial position of the stent (90) relative to the interior catheter (26) whenever the exterior catheter (18) is moved axially relative to the inner catheter (26).  Consequently, precision in stent placement and the abili-ty to recapture a partially deployed stent are enhanced.

Title: Variable filter
Inventor: ERVASTI KIMMO
IPC: H03H7/01
Filed: 1995-01-23
Abstract: An advantageous embodiment of the invention is the filter of the receiver branchof the duplex filter in a multi-channel radio transmitter/receiver having reception and transmission bands composed of plural radio-frequency channels. In the first state of the filter, when the radio transmitter/receiver is only receiving radio signals, the width of the pass band of the filter corresponds to said reception band. In the second state, in which the radio transmitter/receiver additionally transmits radio signals, the pass band of the filter is switched by current control to cover only part of the reception band. By constructing the filter in the manner proposed it is possible to use current control in the first resonator in the filter of the receiver branch. Because of its power consumption current control is otherwise unsuitablefor use in e.g. the duplex filter of a portable radio-telephone.

Title: Peptide Diagnostics and Therapeutics for Spondyloarthropathies
Inventor: SCOFIELD R HAL
IPC: C07K14/74
Filed: 1993-08-31
Abstract: It has been determined that HLA B27 is related to proteins of Gram negative enteric bacteria. The proteins from enteric organisms that share sequence with B27 tend to have sequences that satisfy protein sequence motifs which are thought to predict binding to B27. These sequences (i.e. peptides) are useful for diagnostic and therapeutic purposes and can be used to design additional peptides from Gram negative enteric bacteria which are important for spondyloarthropathies. These peptides can be used to screen for antibodies and T cells which are indicative of spondyloarthropathies. The peptides alone or in conjunction with Beta2 microglobulin or soluble HLA molecules can be used to produce tolerance.

Abstract: A method and an apparatus are provided for safely testing an autotransformer of power distribution lines which has an identified centre tap ground connector, a primary winding terminal and a secondary winding terminal. The method for safely testing the autotransformer includes the steps of disconnecting the terminals and connector of the autotransformer from the distribution lines, applying a first testing AC voltage having a maximum value of substantially  one  volt  only  between  a  first  of  the terminals and the ground connector, measuring a first value of an AC voltage between the first terminal and the ground connector, and measuring a second value of an AC voltage between  the  second  of  the  terminals  and  the  ground connector.  Thereafter, the method includes the steps of applying a second testing AC voltage having a maximum value of substantially one volt only between the second terminal and the ground connector, measuring a third value of an AC voltage  between  the  second  terminal  and  the  ground connector, and measuring a fourth value of an AC voltage between the first terminal and the ground connector. Then, the method further includes steps of comparing the four  measured  values  to  predetermined  constants,  and generating   corresponding   signals   indicating   that autotransformer is short-circuited or that the same is open-circuited. When, the autotransformer being test is not short-circuited nor open-circuited, the method includes the step of generating a signal indicating that the first terminal is the secondary winding terminal or the first terminal  is the primary winding terminal,  whereby the primary and secondary terminals are clearly identified.

Title: Method of Stabilizing the Level of an Audio Signal in Television Broadcasting
Inventor: PLADEK ROBERT B
IPC: H03G3/02
Filed: 1995-07-19
Abstract: To prevent particular transmission equipment from artificially increasing low level audio signals to a predetermined allowable level, such signals are first summed with a stabilization signal having a predetermined frequency toform a composite audio signal. Moreover, the stabilization signal has a level that prevents any increase in signal level that may be artificially imposed on the composite signal during the processing of the composite signal by the transmission equipment. Once the composite signal has been so processed, then the stabilization signal is removed therefrom and the original audio signal is outputted to associated transmission media.
