Patent CA-2201257-A1 (CA)
Title: Apparatus for feeding foil stock in a process for making sealed sterile packages
Inventor: DEY CLIFFORD A
IPC: B65B57/02
Filed: 1997-03-27
Abstract: Automated packaging of surgical needle-suture assemblies includes a framing operation in which adjacent sheets of polymer coated aluminum foils are conveyed through a sequence of steps in an apparatus which produces frames containing plastic packets of needle-suture assemblies. The apparatus pulls a web of foil off a large diameter feed roll and maintains web alignment as it travelsdown line through the apparatus by a system that optically detects transverse movement of the web as it is fed into the apparatus and adjusts the position of the feed roll relative to the centerline of travel using a bi-directional stepper motor. Discontinuities in the polymer coating on the top surface of the web of foil areautomatically detected so that remedial steps can be taken to avoid processing defective sections of the web. A vision system having video cameras connected to a specially adapted computer enables monitoring the product travelling through the apparatus to detect various defects in the product formation. Upon detectionof a defect, the computer system can either identify and separate rejected product from good product or shut down the apparatus. A servo drive system enables rapid and controllable advancement of the web down line in the apparatus.

Filed: 1997-06-06
Abstract: A method and an apparatus for defibering and screening recycled fibre material. In the method, fibre mass is defibered in a primary pulper that is a vertical pulper operating at a high consistency. From the primary pulper the fibre mass is supplied along a transfer conduit (4) to a secondary pulper that is correspondingly a vertical pulper operating at a low consistency. The apparatus comprises a primary pulper that is a vertical pulper operating at a high consistency, and a secondary pulper that is a vertical pulper operating at a low consistency. Between the primary pulper and the secondary pulper there is a transfer conduit (4) along which the fibre mass flows from the primary pulper to the secondary pulper solely by the action of the pressure difference produced by the difference in the fluid levels of the pulpers.

Abstract: A ventilation system for a metal-air battery having a housing for enclosing at least one metal-air cell (10). The housing (20) has at least one air inlet opening (30) and at least one air outlet opening (35). A fan (40) is positioned to force air into the air inlet opening and out of the air outlet opening when the fan is turned on. The openings are sized with a length in the direction through the thickness of the housing being greater than a width in the direction perpendicular to the thickness of the housing. The openings are unobstructed and are sized to eliminate substantially the air flow into the air inlet opening and out of the air outlet opening when the fan is turned off. According to another aspect of the invention, a fan (80) within the battery housing (72) is positioned to distribute air to two separate sets (76-79) of metal-air cells at the same time. In this configuration, all cells of both sets of cells receive air quickly, and the air received is richer in oxygen because the air paths are shorter than in previous configurations utilizing the same number of cells.
