Patent CA-2102324-A1 (CA)
Inventor: BLACKBURN CLAUDE
IPC: F16H55/56
Filed: 1993-11-03
Abstract: The variable speed transmission is for transmitting a torque produced by an engine to a belt. The transmission comprises a shaft connected to the engine, a fixed flange and a movable flange slidably connected to the shaft and substantially  rotatable  thereon.   The  flanges  define therebetween a groove for receiving the belt. A pressure device is rigidly connected to the movable flange.   The pressure device has a pair of pressure units diametrically opposed for  pressurizing  fluids.  Each  pressure  unit comprises a first fluid chamber , a second fluid chamber, a radially  movable  partition  separating  the  first  fluid chamber from the second fluid chamber, resilient means for applying a return force toward the shaft counterbalancing the  centrifugal  force,  and  a fixed  partition  rigidly connected to the shaft. The fixed partition also separates the first fluid chamber from the second fluid chamber. As the centrifugal force urges the movable partitions away from the shaft, the fluids in the first fluid chambers are urged to circulate away from the shaft, and the fluids in the second fluid chambers are urged to circulate, generating a sliding movement of the pressure device and of the movable flange toward the fixed flange. This sliding movement causes a variable transmission of torque from said engine to the belt.

In the event the voltage applied to the electrode and workpiece exceeds the zener diode breakdown voltage, indicating the arc has rectified, an SCR disposed between the resonant circuit and one of the electrode and the workpiece is turned on, thus connecting the source of high voltage to the electrode and workpiece.
Patent CA-2116744-A1 (CA)
Title: Joint Connector
Inventor: CHISHIMA MASAMITSU
IPC: H01R31/08
Filed: 1994-03-01
Abstract: This invention aims to provide a joint connector which makes it easy to insert a tool therein upon detaching a female terminal therefrom and prevents a locking finger from being deformed and impacted.  A locking finger (1d) is arranged inwardly below an outer face of a side wall (1b) of a connector housing (1).  The side wall (1b) is provided on an outer face with an outwardly slanted portion (1h) which inclines and extends outwardly from an end face (1e) opposite to a distal end of the locking finger to the outer face.  The slanted portion (1h) guides a tool (5) to insert it into the connector housing (1).  An upper end of the slanted portion (1h) becomes a fulcrum for the tool and thus a distance between the fulcrum and an acting point of the tool becomes longer.  In order to prevent a short-circuit due to a leak between branched circuits, a coupling portion (25a) of a shorting plate (60) abuts on a distal end of a side wall (12) of the connector housing (1) so that the distal end limit an insertion position of the shorting plate (60).  The connector housing (1) includes first side walls (12a, 12b, 12d) the distal ends of which abut on the coupling portions (25a) of the shorting plates (60A, 60B) for a divisional shorting use and a second side wall (12c) the distal end of which abuts on the coupling portion (25a) of the shorting plate (60) for an all pole shorting use.  In order to avoid interference upon connecting alternately electrical wires directed in opposite directions, a joint chamber (115) is provided between piled terminal accommodating chambers (13), which are communicated with the joint chamber through apertures (112).  The shorting plate (60) is inserted into the joint chamber (115) to confront a given aperture (112).  A female terminal (2) is provided with a tongue piece (22c) which elastically contacts with the shorting plate (60) through the aperture (112).  When the terminal (2) is inserted to the terminal accommodating chambers (13) having openings (131) directed alternately in the reversed directions, the tongue piece (22c) contacts with the shorting plate (60) to electrically interconnect them.  Since the chamber (13) may be arranged through the aperture (112) adjacent to the joint chamber (115), the chamber can be directed in any direction.  In order to use electrical wires having different diameters, the connector housing (1) is provided with terminal accommodating chambers (13) having different sizes so that the housing can simultaneously accommodate electrical wires (91 and 92) with large and small diameters.  Since a contacting portion (22) of each terminal (2) has a common shape, the chamber (13) can accommodate either large or small diameter wires.

Title: A feeding device
Inventor: RASMUSSEN HANS
IPC: A01K5/02
Filed: 1993-01-08
Abstract: A feeding device for feeding animals, such as pigs or hogs, comprises a tubular feed reservoir (16) having a feed discharge opening at its lower end (17). The feeding device also comprises a base member (10) defining a feed support surface (12), which is closely spaced from the lower end (17) of a discharge tube (27) communicating with the reservoir (16). Troughs (11) may be arranged adjacent to the feed support (12), and the bottom surfaces (13) of the troughs are located on a lower level than the feed support surface (12). The reservoir (16) is suspended at its upper part in a pendulum-like manner and transverse movement of the reservoir is restricted by an encircling ring member (18). Animals being fed may push the lower end of the feed discharge tube (27) so that the lower end thereof is moved transversely. The lower length (31) of the feed discharge tube (27) is elastically flexible such that it may be flexed by larger pigs or animals, whereby the lower end of the feed discharge tube (27) may be moved further relative to the base member (10). Thus, the discharge rate of feed adapts itself to the size of the animals being fed.

Title: Pattern recognition adaptive controller
Inventor: SEEM JOHN E
IPC: G05B13/02
Filed: 1993-10-25
Abstract: 2125694 9410613 PCTABS00032 A pattern recognition adaptive controller (20) configured to dynamically adjust proportional gain and integral time control parameters to minimize integrated absolute errors between a setpoint and a monitored controlled variable. The pattern recognition adaptive controller (20) receives a sampled signal representative of the controlled variable, and determines a smoothed signal based on the sampled signal. The controller (20) characterizes a disturbance in the smoothed signal by a damping factor and a closed loop response time. When a significant load disturbance or setpoint change occurs, the controller (20) estimates an optimal gain based on the damping factor, and an optimal integral time based on the response time. The estimated optimal gain and estimated optimal integral time are used to determining a new gain and a new integral time values, to which the control parameters of the controller (20) are then set.

Patent CA-2141233-A1 (CA)
Inventor: ANDERSON NEAL R
IPC: G04G7/02
Filed: 1995-01-27
Abstract: Timing signals are transmitted from reference transmitters through antenna/receivers (antenna preamplifier nodes) to collector nodes (C-Nodes) and to a central computer. The times of arrival of the signals at the various C-Nodes are measured by the C-Nodes, relative to each C-Node's clock. The time of arrival signals at each C-Node must be based upon a common time reference to be useful for positioning. Therefore, the central computer determines the offsets of clocks relative to a selected reference C-Node clock. The time of arrival signals are then calibrated against one another and used to adjust the time of arrival signals so that all time-of-arrivals are relative to the same reference and can be used for position determination and the clocks of the collection nodes are effectively synchronized.
