Patent CA-2140267-A1 (CA)
Title: Improved plant germplasm
Inventor: BRIGHT SIMON W J
IPC: C12N15/82
Filed: 1993-07-29
Abstract: A recombinant plant genome contains a gene cascade such that it is incapable of producing a mature plant but requires the presence of a chemical inducer. The gene cascade includes a gene switch which is inducible by external application of a chemical inducer and which controls expression of a gene product which affects expression of a second gene in the genome. Survival or development of the plant is dependant upon either expression or non-expression of the second gene and application of the indu-cer, therefore, selects whether or not the plant develops. In one example the second gene encodes a cytotoxic molecule and ex-pression of that gene is fatal to the plant. In another example the second gene encodes a desirable characteristic which may be excised selectively by applying or withholding chemical application. The second gene may be placed under control of a develop-ment regulated promoter.

Title: Railroad Car Brake Cylinder Piston Travel Indicator and Mount Therefor
Inventor: KRAMPITZ MARK S
IPC: B60T17/18
Filed: 1995-05-23
Abstract: A visual brake cylinder piston travel indicator for a railroad car having a brake cylinder device located remotely from a convenient viewing area. An indicator rod is suitably sized and configured to extend from the remote brake cylinder device to the viewing area where the brake cylinder piston travel may be determined by the relationship of the indicator rod end with respect to a reference point. At the brake cylinder device, the indicator rod is connected to the piston hollow rod by a bearing assembly that includes the hollow rod collar. The bearing assembly provides for relative rotation between the indicator rod and hollow rod, while concurrently transmitting axial movement of the piston to the indicator rod, such relative rotation being necessitated by the fact that the piston and hollow rod typically rotate during reciprocal movement between a brake application and brake release position, due to torsional forces imparted by the piston return spring.

Title: Composite method and apparatus for fabricating garments
Inventor: RAJALA GREGORY JOHN
IPC: B29C65/00
Filed: 1995-06-21
Abstract: This invention pertains to methods and apparatus for use in constructing a garment including a stretched elastic. Specifically, the invention contemplates incorporating stretched elastic into a continuous web, including one or more segments which exert retractive forces in directions counterproductive to the function of either the web, the garment, or both, and nullifying that portion of the stretched elastic which would be counterproductive. The elastics may be cut at appropriate loci. The stretch may be intermittently reduced or eliminated on one or more selected ones of the elastics as the elastics are incorporated into the web. A special coating may be used on the processing rolls to maintain the width dimension of the web at loci disposed after incorporation of elastic stretched across the transverse dimension of the web. Transverse bonds may be formed on the web using a rotary carrying drum, and energy application devices which rotate with the drum, to increase bond forming time.

Patent CA-2159378-A1 (CA)
Title: Hydronic heating system
Inventor: MACDUFF JIM
IPC: F24D3/14
Filed: 1995-09-28
Abstract: A hydronic heating system for radiantly heating habitable space is disclosed. The radiant heating system uses heated fluid circulated through under-floor or in-wall endless pipe loops and heat radiation fins which clip onto the pipe loops. The system permits heated fluid to be circulated at boiler temperatures, obviating a requirement for mixing valves, heat exchangers or buffer tanks, because the endless pipe loop is spaced away from the wall or floor and all heat is exchanged through convection by air surrounding the heat radiation fins. The advantages include a more affordable heating system due to less pipe, fewer components and faster installation. As well, the system provides a more even heat distribution and the eliminates hot spots. Furthermore, the endless pipe loops are spaced from the floor or wall surface, and thereby protected from danger of puncture by a nail or screw driven through the surface.
