Patent CA-2267726-A1 (CA)
Title: Suspension for a mowing unit
Inventor: FRANET ROGER
IPC: A01D43/10
Filed: 1999-04-15
Abstract: A mower-conditioner includes a header suspended from a mobile, main transverse frame by a pair of lower links, a single upper link and a pair of counterbalance springs. The upper link incorporates a threaded spindle to which a crank is coupled for changing the effective length of the upper link which extends between respective bearings carried by the main frame and the header and in this way pivots the header about the horizontal transverse axis defined by the bearings at the forward ends of the lower links so as to change the cutting angle of the cutter bar incorporated in the header. The upper link is mounted for sliding through the bearing carried by the header so as to permit the header to pivot upwardly about the axis in response to the cutter bar coming into contact with an obstacle during cutting operation. A coil compression spring is received on the upper link and biases it to its full effective length, the spring acting to cushion any impact of the cutter bar with an obstacle tending to tilt the header and acting to return the header to its original position once the obstacle is passed. Counterbalance springs are: coupled between opposite ends of the main frame and opposite sides of the header, the springs being substantially vertically oriented with their lower ends coupled close to the bearings at the fronts of the lower links which bearings are in turn displaced only a short horizontal distance from the center of gravity of the header so as to minimize the moments about the bearings due to the weight of the header and the force of the counterbalance springs.

Title: Manually operated fluid pump for dispensing lotion and the like
Inventor: NELSON PHILIP L
IPC: B05B11/00
Filed: 1997-10-06
Abstract: A manually operated reciprocating fluid pump comprising a pump housing (22), a plunger (24), a piston (82), and a priming valve (92). The pump housing (22) has an inner surface (30) and a pump chamber (38) defined at least in part by the inner surface. The pump chamber (38) extends axially through the pump housing (22). The plunger (24) extends axially into the pump chamber (38). The piston (82) is reciprocally and axially slidable via the plunger (24) and within the pump chamber (38) between a bottom stroke position and a top stroke position. The priming valve (92) is configured to be open and thereby permit fluid to flow upward through the pump chamber (38) when the piston stroke moves the piston (82) from the top stroke position toward the bottom stroke position and configured to be closed and thereby prevent fluid from flowing through the pump chamber (38) when the piston stroke moves the piston (82) toward its tip stroke position. At least part of the priming valve (92) and at least part of the piston (82) are a single monolithic piece.

Abstract: An IP facsimile technique which establishes a real-time IP connection for facsimile transmissions without the use of dedicated facsimile servers. A receiving facsimile device converts a given destination address, e.g., a electronic mail address and/or a telephone number, into a particular IP address associated with a sending facsimile device and utilizing the IP address establishes a direct IP connection between the sending and receiving locations for transmitting the facsimile message. Advantageously, the IP  facsimile communication is made without requiring intermediate message conversions, i.e., hops, and does not require a dedicated facsimile server located in close proximity to the receiving destination.

Patent CA-2272906-A1 (CA)
Inventor: BURDA TIMOTHY PAUL
IPC: B65D85/07
Filed: 1997-11-19
Abstract: In accordance with the present invention, products may be contained within a continuous sleeve which is unitarily formed or joined to itself to form a cylindrical sleeve in a low- or no-tension condition. Products may be inserted into the interior of the sleeve after formation or captured within the sleeve during its formation. The sleeve forms a continuous path encircling the product(s) in at least one plane through the products and package, defining an axial direction normal to the plane and a circumferential direction around the product(s) within the plane. One or more axially-extending pleats are unitarily formed from the material comprising the cylindrical wall of the sleeve, such that the circumference of the cylindrical sleeve is reduced. By reducing the circumference of the cylinder the interior volume of the sleeve, and thus the finished package, is reduced, thus subjecting the products within the package to a compressive force.

Title: Valve prosthesis for implantation in body channels
Inventor: CRIBIER ALAIN
IPC: A61F2/06
Filed: 1997-12-31
Abstract: The present invention is aimed to provide a valve prothesis (IV) especially used in case of aortic stenosis, which structure is capable of resisting the powerful recoil force and to stand the forceful balloon inflation performed to deploy the valve and to embed it in the aortic annulus. A valve prothesis (13) for implantation in a body channel according to the invention comprises a collapsible valvular structure (14) and an expandable frame (10, 10') on which said valvular structure (14) is mounted. The valvular structure (14) is composed of a valvular tissue compatible with the human body and blood, the valvular tissue being sufficiently supple and resistant to allow said valvular structure (14) to be deformed from a closed state to an opened state. Said valvular tissue forms a continuous surface and is provided with guiding means (17) formed or incorporated within, said guiding means creating stiffened zones which induce said valvular structure (14) to follow a patterned movement in its expansion to its opened state and in its turning back to its closed state. The valvular structure can be extended to an internal cover (19) which is fastened to the lower end (15) of the valvular structure to prevent from regurgitation.

IPC: H05B1/02
Filed: 1999-09-07
Abstract: A screwplug type water heater (10) has a heating element (12) immersible in a water heater tank (T) to heat water (L). Electrical terminals (28) on the outer end of the heater connect the heating element into a heater circuit (H) for a control unit (14).  The control unit also includes a sensing circuit (S) for the unit to be responsive to water temperature inputs to turn-on the heater to heat water to a desired temperature and maintain it there. A thermistor ( 16) provides a temperature input to the control circuit. The thermistor is encapsulated in a bracket (32) mounted in, or integrally formed with, the screwplug to sense water temperature. Terminals (36) on the outer end of the heater allow the thermistor to be connected into the control circuit. By integrally forming the thermistor and its support structure, the heater, the entire assembly can be installed or removed as a single unit. Also, the thermistor can readily be made to be removable from the heater, so that it can be removed without removing the heater.

Abstract: A disk scraper system for an agricultural implement includes a tubular member slidably supported by the implement frame adjacent a gang assembly having a plurality of disks. Scrapers are fixed to the member and project into scraping relationship with the disks to remove dirt and debris from the surfaces of the disks. A hydraulic cylinder is connected between the frame and the tubular member and connected through a pressure control valve assembly to a source of fluid under pressure to bias the member so the scrapers are urged into scraping relationship relative to the disks. The pressure control valve assembly may be remotely adjustable to vary the scraper pressure on-the-go as conditions change. The system maintains the selected scraper bias even as the gang assembly moves vertically and from side to side relative to the frame with changing contour and soil conditions.
