Patent CA-2186291-A1 (CA)
Title: Office chair base without castors
Inventor: DEMERDJIEV PETER GUEORGIEV
IPC: A47C3/00
Filed: 1996-10-07
Abstract: All office chairs have to ensure fast and smooth horizontal movement in all directions.  This problem has so far been resolved with the use of castors as part of the architecture of the chair base. In this invention the castors are eliminated and replaced by a freely rotating, centrally located ball and supporting legs with rotating tips.  This is an entirely new approach to resolving the problem and a new aesthetic concept.  This invention also secures independent rotation of the top and bottom parts of the chair base.

Title: Customizable folio system
Inventor: SCHWARTZ DANIEL SOLOMON
IPC: B42D3/04
Filed: 1996-10-23
Abstract: The present invention provides a new customizable folio system that is useful for presenting selectable optical characteristics to one face of a folio cover. The selectable optical characteristics are presented at one face of the folio cover as the result of selective replacement of insert sheet(s) that are placed into a pocket formed between the outer folio cover sheet and an inner backing sheet. Either the outer front face of the folio cover, or the inner backing sheet has at least one cutout section(s) therein, of any desired shape or design, through which selective part(s) of the insert sheet(s) can be viewed. The insert sheet(s) have optical characteristic(s) that are different from those of either the outer front face of the folio cover or the inner backing sheet, at least in those areas of the insert sheet that can be seen through the cutout section(s). The different optical characteristics may include color and/or texture, as well as printing and/or designs that are added to the insert sheet(s) by the folio user, using any suitable imaging method. The different optical characteristics may further include textual, pictorial, and/or graphic material attached to the insert sheet(s) by the folio user.

Title: Methods and apparatus for directionally drilling a bore and placing pipe
Inventor: CRAIGMILE MURRAY P
IPC: E21B7/04
Filed: 1996-12-27
Abstract: The present invention provides an apparatus and method for directional drilling and a method and apparatus for placing pipe in a directionally drilled bore. The present invention provides a launch tube which is placed into unstable soil. The tube is fitted with a unique cutting shoe which forces soil both into and out of the tube to prevent the tube from becoming obstructed. Preferably, the launch tube extends to bedrock or stable soil. Once the launch tube is placed a directional drill is moved through the tube and into the bedrock so that the bore may be directionally drilled in the bedrock. Once the bore is established a pipe, or a plurality of pipes, may be placed into the tube using known techniques.
Patent CA-2194623-A1 (CA)
Inventor: ANTOSHKIW WILLIAM THOMAS
IPC: A61M25/00
Filed: 1997-01-08
Abstract: A catheter designed for improved patency characteristics under forces normally exerted upon the catheter during use. The catheter features an inner wall having one or more protuberances running lengthwise in a manner parallel with the central axis of the catheter. The protuberances include a tip, a root defined along the inner wall, and a pair of sidewalls extending between the tip and the root. The roots of adjacent protuberances are spaced from one another. A fluid path is established between the inner wall and the opposed sidewalls of adjacent protuberances. The opposed sidewalls can be straight. Alternately, at least one of the opposed sidewalls includes a non-linear portionalong its length. In response to a force normally exerted upon the catheter during use, the spacing between adjacent roots and, if so provided, the non-linear portion of an opposed sidewall prevents the opposed sidewalls from entering into total contact with one another, thereby preventing occlusion of the fluid path. If desired, to strengthen the catheter against occlusion by a medical adapter attached to the proximal end, one or more support elements may be incorporated at the proximal end of the inner wall.

Patent CA-2202814-A1 (CA)
Title: Control arrangement for a multilevel convertor
Inventor: FITZ PHILIP JOHN
IPC: H02J3/18
Filed: 1997-04-16
Abstract: A control arrangement for a multilevel convertor employs an AC reference signal which is locked to the AC system frequency and is compared with a number of DC threshold levels. Intersections of the reference signal and threshold levels triggers the firing and turning-off of GTOs within the convertor to produce the desired multilevel voltage output. Normal changes in system voltage, for example, are compensated by variation of the phase relationship of the reference signal with respect to the system voltage, and/or of the voltage values of the threshold levels. Sudden and drastic changes, especially reductions, in system voltage level are sensed and used to alter the amplitude of the reference signal so as to reduce the difference between the convertor multilevel voltage and the system voltage, thereby reducing the stress on the GTOs during faults.
Patent CA-2204680-A1 (CA)
Title: System and method for dynamic time division access
Inventor: BENZIMRA ALBERT
IPC: H04L12/56
Filed: 1997-05-07
Abstract: The present invention is a system and method for providing wireless packet data transmission without dependence on a fixed time slot access method or central timing mechanism. An available radio frequency (RF) channel in a communications network is divided into time frames which are further divided into time slots, wherein corresponding single time slots in each frame define a logical channel for carrying user packet data. The network includes a plurality of nodesdivided into at least two time domain groups, wherein the time domain groups aredivided into segments. Each of the time domain groups includes an independent timing source for synchronizing the time slots of logical channels within a timedomain, wherein communication between nodes is accomplished through a data messaging scheme, such as a token passing scheme. Buffer segments interface between the time domain groups. The buffer segments maintain logical synchronization for communication between interconnected time domains by dynamically reassigning the token from the logical channel of a first time domain to an unused time slot of another logical channel in response to a given offset condition. The logical channel for dynamic reassignment is chosen such that the time slot of a first time domain does not overlap the logical channel used by a second time domain.
Patent CA-2206627-A1 (CA)
Title: Dab receiver, apparatus and method for a format conversion of a dab data sequence
Inventor: SPIERO RICHARD CEES
IPC: H04H40/27
Filed: 1996-09-25
Abstract: A DAB receiver, an apparatus and a method are introduced for converting a first sequence of data having a fixed frame structure, wherein locations within the frame are reserved for predetermined data types, into a second sequence of data, having a different frame structure. The data belonging to the respective data types are grouped in separate sequences with a frame type identifier attached to the sequences for identifying the different sequences. This allows an easy identification of the different sequences of data within the second sequence without the need of prior knowledge of the exact location of the sequences within the second sequence. An example of such a conversion is the conversion of the channel decoder output of a DAB receiver into a format suitable for embedding in the IEC958 format.

IPC: A61K48/00
Filed: 1996-05-23
Abstract: Vaccines based on one or more combinations of majorly abundant extracellular products of pathogens and methods for their use and production are presented. The most prevalent or majorly abundant extracellular products of a target pathogen are selected irrespective of their absolute molecular immunogenicity and used as vaccines to stimulate a protective immune response in mammalian hosts against subsequent infection by the target pathogen. The majorly abundant extracellular products may be characterized and distinguished by their respective N-terminal amino acid, amino acid, or DNA sequences. As the vaccines may comprise different combinations of the extracellular products, subunits thereof, or encoding nucleic acids, a broad range of effective immunotherapeutic compositions are provided by the present invention. In addition to other infectious agents, the vaccines so produced can be used to stimulate an effective immune response against intracellular pathogens and in particular Mycobacterium tuberculosis.
