Patent CA-2203613-A1 (CA)
Title: Secreted .alpha.-amylase as a reporter gene
Inventor: AHLUWALIA NAVNEET K
IPC: C12N9/26
Filed: 1997-04-24
Abstract: The regulation of gene expression is of fundamental importance to all biological functions including adaptation to environmental conditions, cell division and differentiation, and the development of disease states such as cancer. The application of "reporter" gene systems, which allow changes in gene expression to be assayed quickly and easily, has contributed greatly to our understanding of the mechanisms involved in gene regulation. Reporter genes come in two basic varieties; those that encode intracellular enzymes, and those that code for secreted reporter proteins. Most reporter genes currently in use are of the intracellular variety that require manipulation of the cells, normally harvesting and lysis, prior to measurement of the reporter activity. In contrast, cells transformed with constructs that encode secreted reporter enzymes do not require manipulation or lysis of the cells for activity measurements.  Instead, aliquots of the extracellular medium are harvested and assayed directly for enzyme activity. Thus, secreted reporter genes can be used to monitor gene expression in vitro, in vivo and ex vivo. The present invention relates to a reporter gene encoding the chicken a-amylase enzyme for use in transforming mammalian cells. The use of a-amylase as a secreted reporter gene is particularly attractive because the enzyme is extremely stable over a wide range of conditions, measurement of .alpha.-amylase activity is simple, quantitative, sensitive, safe and inexpensive, and the range of electrophoretically-distinguishable variants available allows the assays to be performed in virtually any host without interference from endogenous amylase activities.
Patent CA-2203702-A1 (CA)
Inventor: FOUGERE ROBERT V
IPC: E01H5/06
Filed: 1997-04-25
Abstract: On a plow for the removal of snow, mounted to the front of a truck or other vehicle, it is known to have a horizontal axis about which the moveable portion of the plow frame may pivot, in order to raise the plow blade above the road surface for travelling, or to lower the plow blade to the road surface for plowing. It is also known to utilise a hydraulic cylinder to raise and lower the blade. It is also known to use a chain, cable or other non-rigid element as the actual member which raises and lowers the blade. Thus the blade is raised when the hydraulic cylinder places tension on the chain or cable, and it is lowered by gravity when the hydraulic cylinder releases the chain or cable from tension. In this invention, a damping device, or shock absorber, is mounted between the moveable portion of the plow blade and the headframe which is fixed to the vehicle. The shock absorber controls the motion of the plow blade in both a vertical and horizontal manner that:   (1) when travelling with the blade raised, the bounce and rebound of the blade is substantially reduced. This results in a marked decrease in the incidence of damage to the plow supporting carrier and to the suspension and steering components of the vehicle thus contributing to improved highway safety, reduced operating and repair costs.   (2) when used in the lowered position for plowing snow, the controlled motion prevents the blade from bouncing over minor imperfections on the road surface while still allowing the blade to lift over major obstructions which could cause damage and potential personal injury. This allows for superior plowing performance with fewer passes, thus contributing to improved safety, lower costs and also allows the plow to keep up with the traffic flow when the plow is in a raised condition.

Abstract: The present invention called Air/Water Filled Tubular Units are used in a variety of forms and functions taking advantage of the easy handling of the light weight large diameter tubular units that could be rolled and easily transported at distances due to their light weight, and when said tubular units are inflated; a) as water filled tubular units, said units could be easily pumped with water and stacked over each other to build an instant large volume water barrier, dyke, dam, or the like without occupying much manpower simply by pumping water through these pipes. b) small diameter, air inflated tubular units attached to impermeable membrane water barriers, used as buoyants to lift up said impermeable membranes. c) air inflated tubular units using light weight deflated tubular units as life belts around ships that would occupy little space and when a ship is damaged said tubular units are approached to the damaged area anchored to the lowest point of the ship, inflated and pressurized to a large volume that would transfer its uplifting buoyancy forces to the damaged ship to keep it afloat.   All tubular units are sub-divided internally into chambers provided with inlet/safety valves to allow pumping of the whole tubular unit from one end with provision to prevent sudden deflation in case of the rupture of a unit at one end or the other , resulting in both cases; i- in creating an instant massive water barrier ii-in providing a sinking ship with large buoyancy forces to keep it afloat with very little manpower engagement.
