IPC: C12N1/36
Filed: 1991-10-31
Granted: 1998-09-01
Abstract: Disclosed herein are methods for attenuating virulent Gram negative bacteria to produce avirulent bacteria. The methods comprise passaging the wild-type bacteria through phagocytic cells, such as macr ophages or polymorphonuclear leukocytes, or through lysosomes derived from such cells, a sufficient number of times until th e bacteria become avirulent to the animal host. The bacteria are preferably from the family Enterobacteracea and most preferably from the genus Salmonellae. The invention further comprises the avirulent bacteria produced by the methods, pure cultures of such bacteria, and methods of using the bacteria, preferably in a vaccine for administering to an animal host to induce an immune response to the wild-type Gram negative bacteria in the host.

Patent CA-2103822-C (CA)
Inventor: WEBER GERALD MARTIN
IPC: B32B37/00
Filed: 1992-01-28
Granted: 1995-10-03
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material (1) is formed of at least two plies of material (4a, 5, 6) which are either intermittenly or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies (4a) is stretchable and elastomeric, while the second ply (5, 6) is elongatable, but not necessarily elastomeric. The sec-ond ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration.  This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge por-tions of the laminate web to be incrementally stretched are subjected to restraint to restraint to substantially prevent inwardly directed slip-page or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremen-tal web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.

Abstract: A sensor (32) and method is provided for measuring one or more select components of a material (18). The method measures the components by emitting electromagnetic radiation (42) at the material (18) and detecting the intensity of the emerging radiation at the material at separate locations (36; 37) from the source (38).  The sensor (32) provides a radiation source (38) for emitting radiation (42) at a sheet (18), a plurality of detecting means (70-73, 82, 83, 90, 91, 98, 99), wherein the detecting means are offset from the source (38) substantially the same or unequally, for detecting radiation (42) after interaction with the sheet (18) and first and second reflectors (28, 30) for directing the radiation for multiple interactions with the sheet (18) when moving from the source aperture (34) to the detecting means. The invention can accurately measure the select components (e.g., moisture) of different grades of paper by eliminating the effects of the scattering power and determining absorption power at each band of the spectrum considered necessary for a particular measurement.

Abstract: A variable flow rate expansion valve designed for in-line installation in a fluid conveying conduit such as between the high pressure condenser and lower pressure evaporator of a refrigeration system includes an integrally defined restrictor disc and a closure disc for controlling the flow of fluid through the valve.  The restrictor disc has a first set of flow apertures and the closure disc a second set of flow apertures.  The closure disc is rotatably coupled to the restrictor device in a plane parallel to the plane of the restrictor disc and perpendicular to refrigerant flow.  A stepper motor is coupled to the closure disc through a linear actuator.  Movement of the linear actuator causes the closure disc to rotate relative to the restrictor disc such that the flow apertures of the closure disc are selectively brought into and out of registry with the apertures of the restrictor disc.
