IPC: C08F4/54
Filed: 1999-09-08
Abstract: The process and catalyst system of this invention can be utilized to synthesize a highly random styrene-butadiene rubber having a high traps content by solution polymerization. The styrene-butadiene rubber made by the process of this invention can be utilized in tire tread rubbers that exhibit improved wear characteristics. This invention more specifically reveals a catalyst system for use in isothermal polymerizations which consists essentially of (a) an organolithium compound, (b) a calcium alkoxide and (c) a lithium alkoxide. The subject invention further discloses a process for synthesizing a random styrene-butadiene rubber having a low vinyl content by a process which comprises copolymerizing styrene and 1,3-butadiene under isothermal conditions in an organic solvent in the presence of a catalyst system which consists essentially of (a) an organolithium compound, (b) a calcium alkoxide and (c) a lithium alkoxide. An amine can also be added to the catalyst system to increase the molecular weight (Mooney viscosity) of the rubber.

Abstract: An apparatus and system for automated operation of the brakes on a towed vehicle, in particular the conventional hydraulic brakes on an automotive vehicle, by controlled actuation of its own brake pedal or other such conventional operating component which is normally manipulated by the operator of the vehicle. The preferred embodiment of the system utilizes a power-actuated tension member such as a cable which is attachable to the towed vehicle brake pedal to pull it downward and thus apply the vehicle brakes in controlled response to commands from a controller mountable at a remote location such as on the towing vehicle, and the controller preferably includes, and operates in response to, an inertia sensor and related system which monitors deceleration of the towing vehicle caused by application of its brakes etc., as well as a manual control for selective optional braking of the towed vehicle by the tow vehicle driver at any desired time. The apparatus and system further includes a power unit typically mounted on the towed vehicle (e.g., under the hood) has a drive motor that operates through a controllable slip clutch, preferably a magnetically engageable and controllable clutch device, for generating the pulling force applied to the towed vehicle brake pedal by the cable/tension member. Also, the power unit preferably includes a vacuum pump or other power assist unit coupled to the towed vehicle power brake system unit, to enable use of that system when the brake pedal is pulled down by the cable during the remotely controlled braking process.

Title: Stabilized turf for athletic field
Inventor: LINVILLE STEVE
IPC: E01C13/08
Filed: 1998-06-08
Abstract: A stabilized turf (10) particularly suitable for athletic fields includes a mat (18) interposed between upper (24) and lower (16) layers of growth media, the mat (18) having a horizontally disposed, substantially biodegradable backing (22) and generally upwardly extending non-biodegradable fibers (20) secured thereto, wherein the fibers (20) extend above the upper layer (24) of growth media. Natural grass plants (26) extend upwardly above the upper layer (24), with the roots extending down through the backing (22) and into the lower layer (16). The mat (18) stabilizes root growth, particularly during initial grow in. The substantial biodegradability of the backing (22) results in a loss of all or most of its horizontal structural integrity within a predetermined time period. The backing (22) may be treated with a decomposition agent to control the predetermined time period. Aerating helps to reorient and distribute the non-biodegradable fibers (22) within a subsurface vertical band (22a) greater in vertical dimension than the fibers (22) themselves. The stabilized turf (10) can also be topdressed. Thus, this turf (10) is adapted to accommodate both aeration and topdressing, two well-recognized and advocated turf management practices.

Filed: 1999-12-30
Abstract: A system and method for controlling production fluid flow from a chamber extending between a casing disposed in a downhole bore and tubing disposed in the casing. A plurality of valves are disposed in respective openings formed in the tubing, and a passage is formed in each valve for connecting the chamber and the tubing interior. The valves are selectively closed to prevent any fluid flow through the passage, and selectively opened to permit fluid flow from the chamber, through the passage, and into the interior of the tubing. Thus, the volume of fluid passing from the chamber, through the valve members, and to the interior of the tubing is controlled.

IPC: A61P25/24
Filed: 1999-04-12
Abstract: A method for drying anhydrous paroxetine hydrochloride characterized by comprising: (A) drying anhydrous paroxetine hydrochloride, which has been obtained by reacting a paroxetine compound with hydrogen chloride in the presence of isopropyl alcohol to thereby crystallize the same, in a substantially moisture-free atmosphere at 60 °C under atmospheric pressure until the isopropyl content is reduced to 15 % by weight or less; and (B) then further drying the anhydrous paroxetine hydrochloride under reduced pressure of 20 mmHg or below at 80 to 110 °C until the isopropyl content is reduced to 5 %  by weight or less. By using this method, the isopropyl alcohol remaining in anhydrous paroxetine hydrochloride, which has been crystallized in the presence of isopropyl alcohol, can be efficiently reduced within a short time without resort to any large-scaled apparatus.

Abstract: A display object designed to communicate a message either by imprint of a suitable legend on the display object or by shaping the display object to convey a familiar gesture. The intent of the message becomes apparent by positional change of the display object under the influence of an air-stream, of suitable velocity, such as that generated by vehicles moving at speed. The transformable display has a body adapted for suspension upon a carrying vehicle or a stationary support. A connector has a first end that is configured or constructed to be fixed upon an extending support that is transportable upon a carrying vehicle and an opposite second end coupled to the body. To provide action to the character, the body and the connector are arranged together so that the character ornament is transformable between a fist position and a second position responsively to external forces imposed upon the character ornament as a consequence of the speed of a carrying vehicle. The transforming force typically being the relative wind passing over a traveling vehicle. Typically, the extending support is already mounted exteriorly upon the carrying vehicle with the first end of the connector fixed thereupon. Conveniently, the extending support may be an antenna such as that used for radio reception. The character ornament may be configured to resemble a popular figure such as an athlete or an animal. The connector, or an element thereof, may be configured as one or more limbs such as an arm or a leg of the figure.

Patent CA-2307198-A1 (CA)
Inventor: CLARKE ALASTAIR ROBERT
IPC: A61M5/172
Filed: 1998-10-23
Abstract: An inhalation device which contains powdered medicament in the form of a medicament compact is provided with a seal comprising a partial ring between the outer wall and inner mandrel of the medicament compact chamber. The medicament is dispensed by abrading the medicament compact by turning the compact relative to the inner mandrel against a blade. Despite only extending around part of the circumference of the mandrel the seal prevents leakage of loose powder from the compact chamber to the rest of the device. The sealing means also provides a frictional braking force on the medicament reservoir sufficent to prevent movement of the medicament reservoir when the drive mechanism for the reservoir is returning to its starting position without making the device difficult to operate by a child or infirm adult.
