Patent CA-2063823-A1 (CA)
Title: Pitch guidance system
Inventor: GLOVER J HOWARD
IPC: G05D1/06
Filed: 1991-03-26
Abstract: A pitch guidance system for an aircraft utilizes inertially derived pitch information to provide the pilot with information defining the optimum pitch angle for maximum climb during a wind shear condition. The system utilizes a pitch reference modulator (22) that receives a stall warning discrete from a stall warning system to reduce the commanded pitch angle upon the occurrence of a stall warning to reduce the possibility of stalling the aircraft during degraded performance conditions such as tail winds and engine-out conditions. The system utilizes inertially derived pitch information rather than air mass derived angle of attack information to avoid transients in the angle of attack vane signal, and the commanded pitch angle is biased as a function of altitude (70) and vertical speed (58) to optimize the pitch angle for different altitudes and descent rates.

Patent CA-2067235-A1 (CA)
Title: Modified biological material
Inventor: WHITE DAVID J G
IPC: A61K38/00
Filed: 1990-10-12
Abstract: Conventionally, animal tissue from one species can only be transplanted into another species when the species are concordant;  otherwise, hyperimmune rejection ensues. In this invention, donor tissue is modified, for example by being transgenic, to express or otherwise be in association with one or more substances, referred to as homologous complement restriction factors (HCRFs), which are active in the recipient species to prevent the complete activation of complement and therefore rejection. The invention is in part based on the discovery that the alternative pathway of complement activation, rather than the classical pathway, is responsible for hyperacute discordant xenograft rejection.

Title: Continuously self-compensating hydraulic positioner
Inventor: PORTER CLYDE R
IPC: F16F9/00
Filed: 1992-11-25
Abstract: ABSTRACT OF THE DISCLOSURE    A hydraulic positioner has a cylinder.  There is a piston chamber in the cylinder closed at one end by an axially displaceable gland.  A piston is reciprocable in the chamber.  There is a rod connected to the piston and slidable through the gland.  The rod is moveable with the piston between an extended and a compressed position.          The piston chamber contains hydraulic fluid and there are valve means in the piston actuatable to allow flow of the fluid across the piston.  The valve is normally closed for locking the piston and the rod against movement in the cylinder.  A spring urges the rod to the extended condition.  A further spring urges the gland against the fluid to compensate the changes in fluid volume in the chamber.  The positioner is able to compensate for thermal expansion and contraction of the hydraulic fluid without the necessity to move the cylinder to a particular position after use.  The cylinder of the positioner is also able to compensate for the change in effective piston chamber volume which occurs as the piston rod moves in and out of the chamber during the stroke of the piston.
