Title: Diesel-electric locomotive engine waste heat recovery system
Inventor: GODING DAVID J
IPC: B61C7/00
Filed: 2005-06-08
Abstract: A locomotive diesel engine waste heat recovery system for converting waste heat of engine combustion into useful work. A thermoelectric module is connected to the hot engine exhaust to provide a high temperature heat source, and the engine coolant system is also connected to the thermoelectric module to provide a low temperature heat source.

Patent CA-2511366-A1 (CA)
Inventor: MOREAU THIERRY
IPC: H04L9/08
Filed: 2005-06-30
Abstract: In the field of public key cryptography, e.g. a public key infrastructure, the distribution of trust anchor keys to end-user systems is difficult when the time comes to change the public key, either because a compromise of the private key counterpart is suspected, or as a cryptoperiod policy enforcement. With the present invention, the central organization (from which the trust anchor key originates) is given the opportunity to distribute at once a number of trust anchor keys, in advance of their respective intended period of use, and without exposing the individual public keys to brute force attacks before their actual period of use. At a later time, the central organization distributes unlocking information that enables the use of a public key distributed according to the present invention. The preferred embodiment makes use of an hidden selection of a cryptographic function among a function family.

Title: A control system for a vertical vane covering for architectural openings
Inventor: THOMSON EUGENE W
IPC: E06B9/36
Filed: 1997-09-30
Abstract: A control system for a vertical vane covering for an architectural opening includes a new and improved symmetric headrail having uniquely designed carriers for suspending individual vanes wherein the carriers are designed to minimize skewing relative to a tilt rod as they are moved along the headrail. A pantograph system is utilized to interconnect the carriers, and is connected to the carriers in alignment with the tilt rod so as to minimize skewing. The carriers have pockets formed therein through which the traverse cord extends so that the traverse cord, which moves the carriers along the tilt rod, is secured to a lead carrier closely adjacent to the tilt rod to, again, minimize skewing. Light blocking rails are also attachable to the headrail to substantially bridge the gap between the headrail and the top of the suspended vanes to prevent light from passing therebetween. The tilt rod is keyed to gears in the carriers to facilitate assembly of the control system with all vanes properly aligned.
