Patent CA-2075442-A1 (CA)
Inventor: DESROSIERS JEAN-CLAUDE
IPC: A01K63/10
Filed: 1992-08-06
Abstract: ABSTRACT OF THE DISCLOSURE              The   system  comprises  breeding   and sedimentation tanks both made of flexible material impervious to solid wastes.  The fish breeding tank is lowered in a body of water and comprises a bottom outlet connected to an inlet of the sedimentation tank, also comprising an outlet.   The sedimentation tank is immersed in the body of water beneath the breeding tank.  Floatation members maintains an upper portion of the breeding tank above the level of water in the body, this upper breeding tank portion defining a top opening.  Water is supplied to the breeding tank through the top opening to form a water head that causes a flow of water from the breeding tank to the sedimentation tank.  Water is flowing downwardly in the breeding tank to efficiently carry solid wastes from the breeding tank to the sedimentation tank, where they settle to the bottom.  The upper portion of the breeding tank is of smaller cross sectional area to reduce the volume of water in this tank above the level of water in the body and thereby reduce the load supported by  the  floatation  members.    The  water supplied to the breeding tank is preferably pumped from the body at a deepness where the temperature is optimal for fish growth.  A major advantage of the system is that sedimentation is carried out in a tank separate from the breeding tank whereby contamination of the fish by solid pollutants is minimized.

Title: Energy absorbing mounting systems for motor vehicle windows
Inventor: RAYMOND PAUL J
IPC: B60J10/00
Filed: 1993-11-02
Abstract: ABSTRACT   The invention describes plastic automobile windows that are safe during side impact collisions, including a method for installing the windows into the motor vehicle. The mounting system and window material will contain an occupant in a vehicle at low to moderate head impact velocities. The occupant is not subjected to head injuries. The occupant is not subject to lacerations. The window design uses a high modulus transparent thermoplastic, having an abrasion resistant coating. The window is attached to the window opening in amotor vehicle by using one of several mounting techniques as described herein. For fixed windows, the mounting systems will bond the window to the vehicle under normal operating conditions and provide a weather seal. For a movable window, the window frame will be equipped with a sliding track and provide a weather seal. A groove or notch in the window material inward from the edge in combination with the mounting systems enhance a safe release of the plastic window. By choosing the thickness of the window and specific mounting technique, the plastic window can be made to be pushed out, so that the window remains intact and no injury is made to the impacting occupant's head. The mounting system is designed so that the window will be pushed out and be released from the vehicle in a safe manner. The breakaway zone in the window will break along a notch cut or molded into the window. The window will break and any fragments will be safely released from the window frame by a notch breaking.

Title: A dna sequence and encoded polypeptide useful in the diagnosis of hepatitis disease
Inventor: RYAN TERENCE E
IPC: C07K16/00
Filed: 1993-02-03
Abstract: A novel cDNA clone, 20E, has been isolated and characterized as encoding a previously unknown polypeptide antigen recognized by antibodies in the serum of certain patients with non-A, non-B  hepatitis (NANBH). The nucleic acid sequence is not represented in the genome of the Hepatitis C Virus (HCV). Neither is the nucleic acid sequence represented in the human genome. The data suggest that the RNA sequence corresponding to clone 20E is contained within the genome of an external infective agent other than HCV, and therefore may represent an additional etiologic agent or contributing factor to the development of NANBH in human patients. The 20E  nucleic acid and corresponding polypeptide and respective variants thereof will be useful in a variety of procedures directed at prevention and diagnosis of NANBH.
