Patent CA-2209756-A1 (CA)
Inventor: KAUFHOLD HORST T
IPC: B61F1/10
Filed: 1997-06-25
Abstract: A connection between a draft sill and a railway wheel truck is disclosed. The draft sill has a bottom and side walls extending up from the bottom. A center pin extends downward from the bottom to an exterior end surface. A boss encircles the center pin. The boss is attached to the outer surface of the center pin and to the bottom surface of the draft sill. The boss includes a plurality of ribs extending radially outward from the center pin. The total surface area of the horizontal surfaces of the boss and the center pin is less than the surface area of a standard center plate. The horizontal surfaces of the boss and center pin do not bear any vertical load under normal conditions, and no center plate is provided. The center pin and boss can be integral, and can be made to extend upward from the truck bolster to be received in an opening in the draft sill.

Patent CA-2213878-A1 (CA)
Inventor: CONRAD KEITH JOHN SR
IPC: B44D3/12
Filed: 1997-08-26
Abstract: A paint brush container with improved fastener means comprises a pair of tray-shaped members connected together by a hinge.  A fastener means for the trays comprises protrusions on one of them and mating openings provided through the other tray, where the length of the openings is longer than the width of the protrusions.  As the hinge may wear and develop play, the trays may become out of their initial alignment.  However,  the extended length of the fastener openings easily receives the protrusions to provide a snap latch that maintains the container in the closed position.

Patent CA-2227951-A1 (CA)
Title: Fireplace having multi-zone heating control
Inventor: THOMAS MARTIN
IPC: F24B1/18
Filed: 1998-01-27
Abstract: A fireplace adapted to heat multiple heating zones of a building, controlled by a control circuit which adjusts the heat input to the fireplace, airflow through the fireplace and ducting of the airflow to the various zones individually in response to a call for heat by thermostats in the zones. The fireplace may also be adapted to provide cooled or circulated air to the zones and may also serve to provide heating to the zones in the event of an electrical power outage. The fireplace is provided with a cabinet having ducts through which air is conveyed by use of a fan to a tube-type heat exchanger, the heat exchanger also in communication with the hot flue gases exiting the combustion chamber of the fireplace. The air heated by the heat exchanger is conveyed to a multitude of fireplace outlets, each of which is provided with a damper which regulates the airflow through the outlet to one of the zones to be heated, depending on whether that zone calls for heat through its thermostat. The fireplace is also provided with an evaporator core in an evaporator case, the core being part of an air conditioning system. Air flowing through the fireplace may bypass the cabinet ducts and tube-type heat exchanger, instead being directed to flow through the evaporator core, where it may be cooled, and then to the fireplace outlets for distribution to the zones.

Patent CA-2240168-A1 (CA)
Title: Double worm system
Inventor: BECHER ULRICH
IPC: F04C2/16
Filed: 1996-07-08
Abstract: In prior art designs, single-flight cast double worms with angles of contact>  720° with large balance hollows at both ends and worm lengths of whole multiples of the operate in the medium rotation speed ranges (~3000 min-1) without imbalance. The desired use of special uncastable materials and the manufacturing complexity and the necessary dimensional stability even for extreme profile geometrics pose additional problems in balancing which are solved by the present invention. Here, it is possible, by varying the angle of contact of the worm and any balance hollows and/or by altering the contour of the worms in the medium engagement region, to reduce the size of the balance hollows, sometimes to "zero", and with the possible use of additional masses. Besides the advantage of simple raw component manufacture, worms balanced in this way also permit the use of special materials and extreme worm geometrics for fitting in pumps used in the chemical, medical and food sectors.
Patent CA-2243214-A1 (CA)
Title: Secure data broadcasting
Inventor: MOUNTIFIELD ANTHONY
IPC: H04H20/00
Filed: 1997-03-13
Abstract: The invention relates to a method and apparatus for protecting the destination addresses of data being transmitted over a digital video broadcasting channel.  If the destination addresses are clear (i.e. not encrypted), it is possible for the traffic of data being transmitted to receivers subscribing to the channel to be monitored, and commercial information relating to this traffic may consequently be exposed. The invention provides that the destination addresses are encrypted by calculation from a sequence of control words. The video signal also includes entitlement control messages (ECMs) which include the control words in encrypted form. An address flag is associated with each destination address and a control flag is associated with each control word.  At each receiver, the ECMs are processed to construct receiver addresses by calculation from the received control words and a unique receiver identifier.  The receiver has two address registers for the calculated addresses referred to as odd and even. If the control flag for an ECM indicates odd, the calculated receiver address is registered to update the odd receiver address.  If the control flag for an ECM is even, the calculated receiver address is registered to update the even receiver address. The address flags are also designated odd or even and determine which receiver address each destination address is compared with. Thus, each receiver has two dynamic addresses, one being in use and the other being updated at any one time.
