Patent CA-2214937-A1 (CA)
Title: Zero bounce switch
Inventor: GAROFFOLO NICHOLAS
IPC: H01H1/50
Filed: 1997-09-08
Abstract: To prevent the contacts of an electrical switch bouncing when the switch is operated, with the attendant arcing and contact erosion, spring mass mechanisms are added adjacent the spring arms and contacts to engage such spring arms and contacts and transfer the vibrational energy to such spring mass mechanisms and permit the spring arms and contacts to operate without any contact bounce. An energy absorber can be used alternatively to absorb the vibrational energy. A combination of spring mass mechanism for one spring arm/contact assembly and an absorber for the second spring arm/contact assembly can be employed.

Patent CA-2228201-A1 (CA)
Inventor: SPRAGUE HUGH H
IPC: C10B45/00
Filed: 1998-01-29
Abstract: A system for transporting and burning under negative pressure in a boiler a raw coke oven gas to produce steam energy. The system comprises the usual battery of coke ovens and corresponding ascension pipes connected to a collector main. Flushing liquor is sprayed into the hot coke oven gases to effect cooling in the collector main. A transport main delivers the cooled raw coke oven gases and flushing liquor to a burner of a steam producing boiler where the transport main includes a downcommer for separating the raw coke oven gas from the flushing liquor. The coke oven gas is burned in the boiler where a suction fan is provided at the exhaust of the boiler to develop a negative pressure in the system where the boiler has reinforced walls to withstand the negative pressure. A change in negative pressure in the system is detected and monitored by a controller system which varies draw of the suction fan in response to a detected change in negative pressure in the system. The system is readily retrofitted to existing coke ovens and in turn replaces the usual by-products plant. The generated steam may be used in the co-generation of electrical or mechanical energy. The system may be controlled in a manner to minimize and/or eliminate surplus flushing liquors.

Patent CA-2239925-A1 (CA)
Title: Fluid treatment system and process
Inventor: MAARSCHALKERWEERD JAN M
IPC: B08B9/02
Filed: 1994-03-04
Abstract: A fluid treatment system includes one or more radiation sources arranged in an irradiation zone within a treatment zone through which fluid to be treated passes and is irradiated. The irradiation zone has a closed cross-section to maintain the fluid within a predefined maximum distance from the radiation source. Preferably, the irradiation zone comprises a reduced cross-sectional area perpendicular to the direction of fluid flaw and thus the fluid flow velocity is increased through the irradiation zone. This allows the fluid to enter the treatment zone at relatively law speed, traverse the irradiation zone at high speed and exit the treatment zone again at relatively low speed to minimize the loss of hydraulic head throughout the system. Fluid entering the treatment zone passes through an inlet transition region wherein the cross-sectional area is reduced prior to entering the irradiation zone and fluid exiting the irradiation zone passes through an outlet transition region wherein the cross-sectional area is increased. Each transition region is designed to reduce hydraulic head losses as the fluid flow velocity is increased and decreased. In the irradiation zone, radiation sources are mounted on radiation modules which are arranged to provide improved accessibility for maintenance. The radiation modules may also be provided with cleaning assemblies which are operable to remove materials fouling the radiation sources in situ while the radiation sources are in the irradiation zone.

Patent CA-2243752-A1 (CA)
Inventor: LIVINGSTON PETER M
IPC: F41G3/04
Filed: 1998-07-22
Abstract: An image tracker (10) that tracks an object (16) targeted for engagement by a laser weapon (12).  The tracker (10) includes receiver optics (31) that receive radiation (30) from both a detected target (16) and a laser beam (14) incident thereon, and a polarizing beam splitter (44) that splits the radiation into a first beam of reflected laser radiation (46) and a second beam of detected target radiation (47).  The polarizing beam splitter (44) reflects the first beam of reflected laser radiation (46) in a first direction for imaging purposes and linearly polarizes the second beam of detected target radiation (47).  A beam polarizer (60) circularly polarizes the second beam of detected target radiation.  A micromirror array (66) reflects the circularly polarized detected target radiation back through the beam polarizer (60) to linearly polarize the second beam of detected target radiation (47).  Tracker electronics (33) adjust the reflectivity of the micromirror array (66) to ensure that the radiation incident on the array is at or below a predetermined irradiance threshold level.  Therefore, the reflected laser radiation does not affect the imaging of the targeted object. The linearly polarized detected target radiation beam is then reflected by the beam splitter (44) in a second direction for imaging purposes.  The tracker of the present invention enhances the probability of a target kill, as the actual laser beam hit spot (20) on the target is tracked relative to the target position.

Title: Cryptographic method and apparatus for restricting access to transmitted programming content using program identifiers
Inventor: WOOL AVISHAI
IPC: H04N7/16
Filed: 1998-07-28
Abstract: A system for restricting access to transmitted programming content is disclosed, which transmits a program identifier with the encrypted programming content. A set-top terminal or similar mechanism restricts access to the transmitted multimedia information using store d decryption keys. The set-top terminal preferably receives entitlement information periodically fr om the head-end, corresponding to one or more packages of programs that the customer is entitled to for a given period. Each program is preferably encrypted by the head-end server prior to transmissio n, using a program key, KP, which may be unique to the program. The set-top terminal uses the recei ved program identifier, p, together with the stored entitlement information, to derive the d ecryption key necessary to decrypt the program. Each of the k-bit program keys, KP, used to encrypt transmi tted programs is a linear combination of a defined set of k-bit master keys, ml .... mn. The head-e nd server preferably generates a new set of master keys for the matrix, M, once per billing period. S ince each program key. KP, is a linear combination of the set of master keys, M, a customer desiring r programs, obtains access to the smallest linear subspace of programs, U, that contains those r pro grams. In addition, a package consists of (2i - 1) program identifiers for some i less than n, which n eed not all be assigned to programs. An optional check matrix, C, allows the set-top terminal to determi ne, in advance, whether a received program is in the entitled subspace, U.
