Title: Method of winding strips
Inventor: SHIBUYA SATOSHI
IPC: B21C47/00
Filed: 1999-09-22
Abstract: A method of winding strips wherein in order to prevent a preceding strip from lingering at the outlet side of winding pinch rolls and prevent the front end of a following material from lingering at the inlet side of the winding pinch rolls, a strip fed out of a rolling mill is cut to a predetermined length by snip shears (102) and the cut strip is wound on the mandrel (107) of a winding device (104) via winding pinch rolls (105) disposed at the outlet side of the strip shears (102), the peripheral speed of the winding pinch rolls (105) after the tailing end of the strip to be wound on the mandrel (107) via the winding pinch rolls (105) has been cut by the strip shears (102) being higher than the speed at which the following material is transferred immediately after the cutting and lower than the winding speed at which the strip is wound on the mandrel (107).

Title: Air entrainment with polyoxyalkylene copolymers for concrete treated with oxyalkylene sra
Inventor: WILLIAMS BRENT S
IPC: C04B28/02
Filed: 1999-06-14
Abstract: The present invention relates to a method and air entraining admixtures (AEAs) for achieving satisfactory levels of air entrainment in a hydraulic cementitious composition, such as concrete or mortar, in which an oxyalkylene shrinkage reduction admixture (SRA) is used with, or to be used in combination with, a water soluble salt, such as a calcium salt. Addition of exemplary polyoxyalkylene copolymers, preferably nonionic and substantially di-block in structure, and preferably having a molecular weight of at least 1,000 and more preferably at least 2,000, are described for controlling air entrainment.  Increased air entrainment effect is further realized when such polymers are used with conventional AEAs, such as tall oils and vinsol resin.

Patent CA-2336575-A1 (CA)
Inventor: KOLLER ERWIN
IPC: H04B10/2513
Filed: 2001-02-14
Abstract: The present invention relates to a method for transmitting binary data at a rate of R bits per second via an optical conductor of length d. A transmitter produces pulses of duration ~, which is considerably shorter than the bit period 1/R associated with the rate R. Owing to the dispersive characteristics of the optical conductor, these pulses are broadened on their path to the receiver to a value which is approximately equal to the bit period 1/R. One advantage is that there is no a priori need to use a laser with a narrow spectral width to achieve a long transmission distance d.

Abstract: L'invention porte: sur des composés se fixant à des toxines associées à des infections à entérobactéries, sur des compositions comprenant ces composés; sur des procédés de neutralisation de toxines chez un patient, et sur des méthodes de diagnostic des infections bactériennes et virales. Les toxines auxquelles se fixent les composés comprennent des toxines pentamères telles que les SLT, par exemple celles de la salmonella, du camylobacter et d'autres bactéries, les vérotoxines du E. coli, les toxines du choléra, les toxines des clostridium difficile A et B, le pili bactérien du E. colientéropathogénique (EPEC) et du E. coli entérotoxigénique (ETEC) ainsi que des lectines virales telles que les hémagglutinines virales. Ces composés comportent une molécule noyau liée à plusieurs bras de liaison, à leur tour liés à plusieurs fragments de pontage, à leur tour liés à un ou de préférence plusieurs ligands qui se fixent à la toxine. Parmi les ligands idoines se trouvent des fragments de di et trisaccharides se fixant eux-mêmes aux SLT. La présence des différents dimères pontés des ligands est responsable de l'affinité accrue de liaison des composés vis-à-vis des ligands eux-mêmes. Dans l'une des exécutions, les composés administrée à temps à un patient souffrant d'une infection à E. Coli, l'empêchent de dégénérer en syndrome de Gasser.

Title: Methods and apparatus for crossing vascular occlusions
Inventor: MILO CHARLES F
IPC: A61B19/00
Filed: 1999-08-27
Abstract: Methods and apparatus for crossing totally to substantially occluded blood vessels by passing a redirectable wire such as a guidewire from a relatively  proximal point past the occlusion within a subintimal space formed between t he intimal layer and the adventitial layer of a blood vessel wall. The wire may  be advanced to a point distal to the occlusion, and thereafter deflected bac k into the blood vesel lumen, typically using a deflecting catheter which is advanced over the guidewire after it has been positioned within the subintim al space. The deflecting catheter may include a flapper valve assembly or preformed actuator wire for redirecting the guidewire. After the guidewire i s returned to the blood vessel lumen, the deflecting catheter may be withdrawn , and the guidewire may be available for introduction of other inverventional and diagnostic catheters for performing procedures such as stenting.
Patent CA-2342051-A1 (CA)
Title: Semiautomatic control system and method for vehicles
Inventor: FRANKE RUDIGER
IPC: B61L3/00
Filed: 2001-03-26
Abstract: The present invention relates to a semiautomatic control system or control method for ensuring a driving method which is as energy-saving as possible. In this system, there is both manual inputting of control data, for example a definition of a vehicle speed specified value, by the driver of the vehicle and automatic determination of the most energy-saving vehicle speed as a function of predefined peripheral conditions, for example a general travel schedule, the topology of a route, vehicle-specific peripheral conditions and the like. An inference system is used to determine which of these two values is smaller, and is therefore used to make possible safe and at the same time energy-saving travel (or journey).      Additionally, a safety check of the manual travel speed input value and of the automatically determined travel speed specified value can also be carried out in order to reliably prevent a maximum permissible travel speed value from being exceeded.

Title: Apparatus for and method of stacking articles
Inventor: WOODY CLARK
IPC: B65H31/10
Filed: 2001-05-30
Abstract: An apparatus for and method of stacking flexible articles of a non-uniform thickness involves the use of a stacking table including separately movable first and second support surfaces. An actuator moves the stacking table through a range of motion relative to a stationary cam plate. A cam follower is mechanically coupled to the second support surface and engages the cam surface when the stacking table is moved through at least part of the range of motion. When the actuator moves the stacking table and the cam follower engages the cam surface, the second surface is displaced relative to the first support surface. Preferably, the cam plate is repositionable to vary a distance by which the second support surface is displaced relative to the first support surface.

Title: Improved process and apparatus for preventing oxidation of metal
Inventor: SWANNIE MARK
IPC: C23F13/00
Filed: 2001-12-10
Abstract: An apparatus for prevention of corrosion in metal objects uses a capacitively coupled fastener or pad attached to a metal body being protected from corrosion. The metal body and the negative terminal of a source of DC voltage (battery) are grounded. The positive terminal of the source of DC voltage is connected to electronic circuitry that imparts pulses of low voltage DC through the capacitor to the fastener. These pulses of electrical current inhibit the oxidation of the metal object by providing a source of electrons to the oxidizing chemicals in contact with the metal. The electronic circuitry includes a reverse voltage protector to prevent the application of reverse source voltage. The circuitry also includes a power conditioner to supply a constant DC  voltage to a microprocessor. The microprocessor generates pulses of DC signals that are amplified by a pulse amplifier and imparted to the conductive facing of the pad. For larger objects, a first and second cable are attached to a metal object. A phase compensated signal is applied to each cable to provide a phase synchronous signal at the metal object. The invention also includes a battery voltage monitor and a power indicator to indicate battery level. When the battery voltage drops below a reference level, the microprocessor senses this low voltage condition and shuts off operation of the pulse amplifier, thereby conserving battery power.
