Patent CA-2242431-A1 (CA)
Inventor: DE VLAAM HENK
IPC: B65B13/02
Filed: 1998-07-06
Abstract: For strapping substantially parallelepipedic objects or stacks which are conveyed into a strapping position (U) and out of this position after strapping, a strapping tape (3/3') extending in a starting position substantially straight from one side of the conveying path to the opposite side is formed into a tape bow with the help of two tape positioning means (6 and 6') arranged on the two opposite sides of the conveying path. Then, the object to be strapped is conveyed into the tape bow and the tape is tensioned around the object and is closed around the object and cut off the tape supply in the region of its starting position such that the object is strapped and the tape (3/3') is again in its starting position. By adapting the size of the tape bow according to the format of an object to be strapped, the tape does not have to be pulled back for tensioning it around the object or stack. Therefore, the device is simple and the time required for strapping is short.

Patent CA-2248047-A1 (CA)
Inventor: ADAMS MICHAEL A
IPC: A61K48/00
Filed: 1997-03-13
Abstract: The mechanism of hypertension following acute NO synthase blockade is via endothelin-mediated vasoconstriction. Thus, NO appears to inhibit endothelin activity by blocking its expression and not as a chronic direct acting vasodilator. Administration of an endothelin antagonist to a patient in a 'normal' physiological state may result in specific regional vasodilation.  This treatment finds utility in the treatment of erectile dysfunction.

Patent CA-2253425-A1 (CA)
Title: Trileaflet heart valve
Inventor: MORE ROBERT B
IPC: A61F2/24
Filed: 1998-11-04
Abstract: A trileaflet heart valve includes a generally annular valve body having an interior wall of nominally circular cross-section into which three wedge-shaped projections radially extend to provide three pairs of flanking flat surfaces between which three leaflets are pivotally supported. The valve body has an outwardly flaring upstream entrance end that, together with the configuration of the leaflets, assures streamlined flow and low transvalvular pressure drop. Wing sections extend laterally in both directions at angles between about 30° and 50° from flat central sections of the leaflets to create V-shaped cross-section leaflet bodies having short flat edge sections along the lateral edges of both wing sections that create a wide open central flow passageway.  The three leaflets assume an orientation parallel or nearly parallel to the central axis in full open position.  Leaflet movement from open to closed position is partially defined by upstream retainers aligned with the flat central sections of each leaflet and by surfaces formed in or on the side walls of the projections along which the leaflets slide. Radially interior edges of the leaflets are tapered to effectively eliminate cavitation.

Title: Apparatus for continuous purification of liquids, dewatering and drying of the separated solids
Inventor: BELCHEV BELCHO ALEXANDROV
IPC: C02F11/123
Filed: 1997-10-08
Abstract: The invention discloses an improved apparatus for continuous purification of liquids, dewatering and drying of the separated non-filtering solids. The apparatus is intended to be applied for the purification of industrial or household waste liquids, as well as water from natural sources, by separating and drying of non-filtering solids. The apparatus can be applied successfully for dewatering and drying of various slurries without the emitting of vapours, dust and other detrimental substances in the atmosphere. The apparatus includes a belt filter (1) with an incorporated filter sector and an elastic thermo-filter press (35). The belt filter ensures a continuous purification of water from different sources by separating the non-filtering solids and detrimental ion components comprised in the water, and ensures their bacterial sterility. The separated non-filtering solids are permanently accumulated in the belt filter, and are mixed with the water fed to be purified forming together a slurry. The thickness of the slurry is permanently increasing. After reaching a definite value of thickness, the slurry is pumped by a thickening cone mounted under the filter sector, and is compressed to be dewatered and dried in the elastic thermo-filter press. The cake compressed in the chambers of the elastic thermo-filter press is dewatered and dried in two stages: The first stage is effected by the pressure of a combined vacuum pressure pump, and the vacuum generated by a second vacuum pressure pump. The second stage is realized simultaneously by the longitudinal shrinkage of the elastic thermo-filter press which squeezes the cake, by the extraction of the residual capillary moisture under the action of a "steam jacket" generated by the partially evaporated residual liquid phase, and by the vacuum created by the second vacuum pressure pump. The apparatus can be used successfully for dewatering and drying of different types of slurries, and the power consumption is substantially reduced.

Title: Single-piece piston for use in a pneumatically-activated pump
Inventor: WECH MICHAEL J
IPC: F04B53/14
Filed: 1999-08-16
Abstract: A single-piece piston used in a pneumatically-activated pump or other metering device for metering predetermined amounts of liquids. The piston is disposed within a metering device body chamber. The piston includes a head portion and a cicumferentially-disposed channel for containing a sealing member. An adjacent stem section includes means for providing a fluid-flow connection with the angled channel. Lateral movement of the piston causes the sealing member to shift and block and unblock the fluid-flow connection means, allowing liquid to flow out the head of the piston's grooved end and to an adjacent pump chamber.      The piston operates in association with an assembly for regulating the amount of liquid metered by the lubricator, a valve assembly for evacuating the liquid from the pump chamber into an outlet fitting, and a mechanism for regulating the flow of air into the outlet fitting to atomize the liquid. The piston operation can be calibrated for precise liquid metering.
