Patent CA-2067527-C (CA)
Inventor: LADOUCEUR HAROLD A
IPC: B23P19/06
Filed: 1992-04-29
Granted: 1996-09-17
Abstract: A die member for joining a fastener to a panel includes a generally rectangular opening defined by two spaced apart opposed end walls, which receive the end walls of a pilot portion of a fastener. The end walls of the opening terminate into arcuate corners and are adapted to sheer and deform the pilot end walls of the fastener thereby forming bearing panel support abutments capable of providing a liquid tight seal between the panel and the fastener. The die member also includes clinching lips on opposed sides of the die opening. The clinching lips preferably include a top portion and tapered wall which deform the panel edges into grooved openings in the fastener thereby providing a liquid tight seal. The die opening is surrounded by a generally planar surface having an outer generally rectangular perimeter having generally arcuate corners. The generally arcuate corners form arcuate depressions within the panel when the die member operates on the fastener to attach it to the panel. The arcuate depressions resist stress fracturing of the panel when the panel and fastener assembly is subjected to high vibrational environments.

Title: Continuous production of iron-carbon alloy using iron carbide
Inventor: GEIGER GORDON H
IPC: C21B13/14
Filed: 1991-10-09
Granted: 1997-03-11
Abstract: A process for the continuous production of an iron-carbon alloy utilizing an enclosed reactor (10) capable of limiting the ingress and egress of atmospheric gases and gas reaction products respectively.  A solid mineral material (20) containing iron carbide and at least trace amounts of iron oxide, and having a weight ratio of at least about 2:1 or greater, is fed into a molten bath (12) of metallic material in the reactor (10).  The molten metallic material is simultaneously reacted with oxygen at a temperature sufficient to generate carbon monoxide as a reaction product.  The oxygen is preferably injected into the molten metallic material to facilitate the reaction of the oxygen with carbon from the iron carbide to form the carbon monoxide.  The carbon monoxide subsequently enters a vapor space (17) of the reactor (10) above the molten bath (12), and further reacts with oxygen to generate carbon dioxide and heat.  Products of the described method are also disclosed including a continuous supply of molten iron-carbon alloy.  The system or equipment utilized in the present process is also disclosed.

Title: Method and apparatus for improving vertical sharpness of picture tubes
Inventor: HACKETT ANDREW DENYS
IPC: H04N3/30
Filed: 1991-09-06
Granted: 2001-06-12
Abstract: Large format TV tubes must produce a high peak brightness in order to be acceptable to the user. This results in a large beam current in bright areas of the picture and in a subsequent defocussing of the resulting spot on the display and in a loss of the sharpness of vertical and horizontal transitions. The apparent sharpness of a vertical transition is gained by modifying the deflection of the TV receiver such that, at vertical transitions, the line on the bright side of the transition is deflected away from the transition region. Advantageously the amount of vertical scan modulation corresponds to a multi-level control signal and de-pends on the grey levels of the transition.

Patent CA-2100542-C (CA)
Inventor: DERBY JEFFREY HASKELL
IPC: H04L12/66
Filed: 1993-07-14
Granted: 1999-02-16
Abstract: Access agents in nodes at the LAN/WAN interface are formed into a group of access agents so that the access agents may be managed by the WAN as a group. The group must maintain group operation integrity in that if communications between agents  in the  group  are broken,  the  access  agents will coalesce   into    subgroups    and   continue   performing communication jobs as a group activity.  Each of the access agents contains a finite state machine to perform the tasks of  group  formation  and  maintenance.   The  formation  of interconnected access agents into a group is accomplished by one access agent being identified as a group leader.  All other  access  agents  communicating with the  group  leader within the LAN may then join the group.  The maintenance of group  activity  integrity  is  accomplished by detecting  a break  in  group  communication  integrity  and  thereafter reforming  the  group  into  multiple  smaller  groups.   The maintenance of group operation integrity also includes the merger of small groups into a large group when a bridge is added between LAN segments.

Granted: 1998-04-28
Abstract: A thermostat and method for controlling the overshoot and undershoot of the temperature in a zone that are caused by an air conditioning system responsive to a change in the setpoint of the thermostat is disclosed.  The thermostat includes a sensor for detecting the temperature in the zone and being adapted to generate a signal representative of the temperature.  A processor for controlling the air conditioning system is communicatively coupled to the sensor and receives the signal representative of the temperature of the zone therefrom.  A setpoint input device for changing the setpoint of the thermostat is communicatively coupled to the processor and is adapted to provide a signal representative of the changed setpoint to the processor.  The processor controls the air conditioning system in a static condition mode during normal operations and switches the air conditioning system to a full on mode responsive to a setpoint change.  The processor is adapted to generate a time based target temperature curve and to compare the target temperature with the temperature in the zone at certain time intervals after the input of the setpoint change.  The air conditioning system is switched by the processor from the full on mode of operation to the static condition mode of operation when the sensed temperature in the zone equals the temperature of the target temperature curve.
