Patent CA-2168092-A1 (CA)
Title: Manufacture of paper
Inventor: CUTTS PAUL KENNETH
IPC: D21H23/76
Filed: 1995-06-01
Abstract: Paper is made by forming a thick stock cellulosic suspension, flocvulating the thick stock by adding a relatively high molecular weight and relatively low cationic charge density polymer, diluting the flocculated thick stock to form a thin stock and then draining the thin stock to form a sheet. Usually coagulant is added to the thin stock before drainage and best results are achieved by adding coagulant followed by anionic colloidal material such as bentonite. The process can be operated to give good retention and good formation and, if the thick stock is dirty, to minimise pitch problems.

Patent CA-2172432-A1 (CA)
Inventor: WOODMAN STUART D
IPC: A62C35/68
Filed: 1996-03-22
Abstract: A master/slave discharge valve assembly for pressurized fluid containment systems includes a primary valve chamber, for connection to a fluid pressure source, formed by an eccentrically disposed first longitudinal bore and a secondary valve chamber defined by a second bore generally parallel to that of the primary chamber, communicating at one end with the primary valve chamber and at the other end with a discharge port.  A displaceable primary valve member is positioned within the primary valve chamber.  A slave valve member and an actuating piston are positioned within the secondary valve chamber.  A predetermined pressure in the discharge port displaces the actuating piston to open the slave valve member and permit a holding portion of pressurized fluid to vent to the atmosphere, thereby permitting the pressurized fluid to open the first valve member and allow pressurized fluid out the discharge port.  A master/slave valve assembly according to the invention is of lower cost to manufacture as well as simpler and sturdier in construction than known valves for carbon dioxide fire suppression systems.

Patent CA-2179817-A1 (CA)
Inventor: BIRCHENOUGH CHARLES W
IPC: B60W30/18
Filed: 1995-11-17
Abstract: A control system (30) is provided for vehicle regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system (30) includes separate microprocessor based engine and transmission controllers (32, 34) which communicate via a data link (36). When a shift is initiated the transmission controller (34) delays a first period of time CTSDELAY sufficient for the transmission (14) to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller (34) continues to produce the CTSSPEED signal for a second period of time CTSDUR which corresponds to the time required for the transmission (14) to engage the new gear ratio. The control system (30) preferably includes means for sensing a lockup time period corresponding to the time required for the transmission (14) to lock up in the new gear ratio. The control system (30) is capable of modifying the second time period CTSDUR as a function of the sensed lockup time period.

Patent CA-2183248-A1 (CA)
Inventor: PUTTERMAN SETH J
IPC: G21B1/00
Filed: 1995-02-21
Abstract: La sonoluminescence est un phénomène de déséquilibre dans lequel l'énergie d'une onde sonore résonnante dans un liquide est fortement concentrée, afin de produire des éclairs de lumière. La conversion du son en lumière représente une amplification d'énergie équivalente à 11 ordres d'amplitude. La phase initiale de la focalisation de l'énergie est réalisée par les oscillations non linéaires d'une bulle de gaz piégée dans le liquide en question. Pour obtenir des pressions d'attaque suffisamment élevées, une onde de choc implosive est projetée dans le gaz par la bulle qui se dégonfle. La réflexion du choc à partir de son point focal produit des températures et des pressions élevées. Des formes d'énergie différentes de la lumière peuvent être obtenues à partir de l'énergie acoustique convertie. Lorsque le gaz contient du deutérium et du tritium, on peut réaliser la fusion comme autre forme d'énergie, c'est-à-dire une forme d'énergie générant des neutrons.

Abstract: In a flexible meshing type gear device (1), the amount of radial flexing (w) in a basic section defined perpendicular to the axis of the flexible external gear (3) at a prescribed point on the tooth trace of the flexible external gear (3) is def fined to be an amount of negative deviation flexing smaller than the normal amount of flexing (W0) The rigid internal gear (2) and the flexible external gear (3) are both spur gears and the number of teeth of the flexible external gear (3) is 2n (n being a positive integer) fewer than that of the rigid internal gear (2).      The working tooth profile of one of the gears (2, 3) is defined to be a convex curve whose shape is or approximates a convex curve (L2(O,B)) obtained by similarity transformation of a peak portion (L1(O,A) of the rack-approximated moving path (L1) of a tooth of the gear with respect to the other gear in the basic section of the tooth trace perpendicular to the axis, the portion being convex relative to the other gear, at an enlargement ratio (.lambda.) using the apex of the moving path as the origin. The working tooth profile of the other gear is defined to be a concave curve whose shape is a concave curve (L3(O,C)) obtained by similarity transformation of the same portion of the moving path at an enlargement ratio (.lambda. + 1) using the apex of the moving path as the origin. The meshing of the two tooth profiles is pass messing enabling continuous contact in the basic sector perpendicular to the axis and the ability to retain a lubricating oil film between the tooth surfaces is enhanced.

Title: Sealed relay device
Inventor: PERREIRA G STEPHEN
IPC: H01H51/06
Filed: 1995-03-03
Abstract: A sealed relay (1) of the high-vacuum type, or which may be backfilled with a dielectric gas such as hydrogen-nitrogen mixture for improved arc suppression when switching high-voltage DC currents. The relay (1) uses controlled fixed contacts (22) which enable use of a reduced diameter disk-shaped movable contact (21), thus permitting optimal placement of external arc-supporting permanent magnets (30) on a ceramic relay housing (3) in close proximity to the enclosed fixed and movable contacts (21, 22). A staggered or offset position of the fixed contacts (22) makes the relay polarity insensitive for bidirectional switching of high-voltage DC currents.

The encoded polypeptide is surface exposed on the bacterial surface, it is highly conserved, and is thus potentially useful as a vaccine agent and as a diagnostic agent in the diagnosis of infections with B. burgdorferi as are the characteristic nucleic acid fragments of the invention. Also disclosed are methods of producing the polypeptide antigen according to the invention as are antibodies directed against the antigen.
