Title: Display system
Inventor: WOLCOVITCH BRIAN
IPC: A47F5/08
Filed: 1992-07-17
Granted: 1999-06-01
Abstract: BP File No. 6989-001 ABSTRACT OF THE DISCLOSURE                       A display  system  comprises  an  elongate  arm having a flange at one end and a holder at the other end for receiving and supporting an object to be displayed, and a display panel having a generally upright front face. At  least  one  slot  is  located  in  said panel  and  is accessible from said front face.   Each slot extends at least partially across the front face of the panel.  Each of said slots are adapted to receive said flange through said front face in a compression fit to removably retain and support the holder in a spaced relationship from said front face.  Lateral extensions of the flange on an arm may act as spacers for providing a minimum lateral spacing between adjacent arms in a slot.  Where said object is an eyeglass frame, said holder includes a frame retaining means comprising a raised portion intermediate the ends of the holder to prevent the frame from sliding along the holder.

Abstract: This invention relates to a composition comprising a tramadol material and a nonsteroidal antiinflammatory drug, and its use. The compositions are pharmacologically useful in treating pain and tussive conditions. The compositions are also subject to less opioid side-effects such as abuse liability, tolerance, constipation and respiratory depression. Furthermore, where the components of the compositions are within certain ratios the pharmacological effects of the compositions are superadditive (synergistic).

Patent CA-2102328-C (CA)
Inventor: WU ALLEN
IPC: H03H17/00
Filed: 1993-11-03
Granted: 2002-10-15
Abstract: A two stage accumulator is provided for updating coefficients. The accumulator is particularly useful in an adaptive equalizer. A first stage of the accumulator receives an error word and outputs sign and carry bits resulting from the addition of the error word and an N-bit LSB portion of a larger M-bit coefficient. A second stage is responsive to the sign and carry bits for updating the (M-N) MSB's of the M-bit coefficient.        New error words are cyclically provided to the first stage during successive coefficient update cycles.      The first stage can be implemented using an N-bit twos complement adder. The second stage can be implemented using an up/down counter. A leakage function is provided by causing the up/down counter to periodically skip over increment and decrement cycles.

Title: Hydrogen/oxygen fuel cell
Inventor: STOWE GENE B
IPC: C25B9/17
Filed: 1993-03-10
Granted: 2005-05-31
Abstract: An electrolysis cell (33) is provided for use in connection with a combustion engine (10), for generating hydrogen and oxygen gases which are added to the fuel delivery system as a supplement to the gasoline or other hydrocarbons burned therein. The hazard of explosion of the mixture of generated gases is eliminated by withdrawing the gases through a connection with the vacuum line of the positive crankcase ventilation (PVC) system (45) of the engine and by utilizing a slip-fitted top cap for the electrolyses cell, which cooperates with the PVC vacuum line to prevent explosive containment of generated gases in case of accident. Use of the generated gases as a fuel supplement enables substantial increases in fuel efficiency, while at the same time reducing the emission of pollutants.

Abstract: A container base (5) is adapted to receive various types of side-boards owing to a new corner structure. The corner structure is characterized in that coupling means can be inserted in two mutually perpendicular horizontal directions and in a vertical direction. This is achieved in that a pair of pipe profiles (10, 11) has open ends to receive coupling means, and by the provision of a further pipe profile (12) which extends perpendicularly to the pipe profiles (10, 11). The further pipe section is germinated at the same level as or below the lower side wall of the substantially horizontal pipe parts and is secured to the lower wall edges of these. All pipe profiles are located in such a way that they do not prevent introduction of a coupling means into any of the pipe profiles of the corner.

Abstract: A cover (10) is for use on a multi-cylinder overhead camshaft engine (20) having a pair of projecting members (112, 120). The cover (10) has a plurality of walls (300-308) for intercepting oil sprayed from the camshaft (80) of the engine. A pair of tubular projections (328, 330) connected with one wall (300) of the cover are engageable in a press fit relationship with the projecting members to support the cover in a position adjacent to the camshaft.          A plurality of ribs (310-324) are disposed generally above the camshaft and extend parallel to the camshaft for catching and collecting oil sprayed from the camshaft and for dripping the oil down onto the camshaft. A W-shaped rib (326) on the inside of the cover collects oil flowing along the inside of the cover. The oil drips down from points (476, 486) of the W-shaped rib to lubricate selected portions (180, 206) of the engine. A multi-cylinder cover assembly (42, 60) encloses a plurality of the covers (10).          A respective cover (10) is associated with each respective cylinder assembly (30) of the engine (20). The walls of the cover (10) block flow of oil onto the joints of the multi-cylinder cover assembly (42, 60) to minimize leakage.

Granted: 2001-06-12
Abstract: To recover the sodium-sulphur compounds  following sodium-based pulp processing, e.g. the ASAM process or basic or acidic sodium sulphite processes, the waste liquor is burnt in a lye burning vat (1) with liquid slag extraction and the exhaust gases are subjected to multi-stage purification with dry fly-ash recovery and the gaseous sulphur compounds are also separated in a multi-stage washing process. The water-soluble components of the fly-ash are taken to the waste liquor to be burnt and thus the sulphur to be recovered in the slag is increased. The slag is dissolved in water and the dissolved sodium compounds are converted by multi-stage carbonisation    with a part of the purified flue gas into sodium bicarbonate and H2S. The H2S is burnt and finally converted into sodium sulphite so that the desired lye for pulping cellulose can be made up from sodium sulphite and carbonate.

Granted: 1998-12-22
Abstract: A leakproof seal arrangement is disclosed for use in the drivehead of a downholerotary pump, which pump is operated by a drive string suspended from the drivehead for rotation in a production tubing about a longitudinal axis, the drivehead having a bore in fluid communication and coaxial with the production tubing and sized to permit the passage of a polished rod attached to a top end of the drive string. The seal arrangement includes a centralizer sleeve for receiving a portion of the polished rod; a bearing for rotatably supporting the centralizer sleeve in the drivehead coaxial with the bore, whereby an annular gap is created between the centralizer sleeve and an opposite, cylindrical wall of the drivehead which gap is in fluid communication with the production tubing. The seal arrangement further includes a centering packing for sealingly and concentrically connecting the centralizer sleeve with the polished rod for simultaneous rotation about the longitudinal axis. The centering packing is sufficiently elastic to accommodate wobble of the polished rod in the centralizer sleeve while preventing leakage of a pumped liquid present in the production tubing and the centralizer sleeve during operation of the pump. The seal arrangement also includes an annular drivehead seal for sealing the annular gap which is also filled with the pumped liquid during operation of the pump, to substantially prevent leakage of the pumped liquid from the drivehead. With this seal arrangement, polished rod wobble compensation and sliding sealing of the drivehead are carried out at separate locations in the drivehead which results in a more reliable seal and reduced stress on the seal materials used and provides the seal with an extended service period.
