Patent CA-2057256-A1 (CA)
Inventor: KUSCHEL DAVID
IPC: B65G47/26
Filed: 1991-12-09
Abstract: A clutch and declutch assembly is disclosed for live conveyors that is particularly suitable for conveyors having sections or zones.  The clutch assembly has a clutch biasing spring and nut assembly which causes inner and outer driven clutch members to frictionally engage the driving clutch member.  The clutch also has a torque limiting feature and a declutching feature.  Declutching is performed by expanding a bladder or a hydraulic cylinder, causing a clutch release plate to axially move the outer driven clutch member to disengage with the driving clutch member.  A zoned live conveyor is obtained by using at least one live roller, sensor and valve in each zone. When the presence of a load unit in a zone is sensed, a sensing signal is sent to a central control unit, which in turn operates a valve to expand a bladder or cylinder that axially move the clutch release plate to declutch the roller.  A variety of control logics can be programmed into the control unit and are easily changed.

Title: Apparatus and method for generating a transition between the on and off states of a radio frequency transmitter
Inventor: WALCZAK THOMAS J
IPC: H03G3/30
Filed: 1992-06-19
Abstract: An apparatus and method generates a shaped transition between the minimum and maximum output power levels of a transmitter (500). When the transmitter is turned on a stepped transition (415) is generated at the beginning (3) of the transition region (409) followed by a shaped transition (417) to the end (6) of the transition region (409). When the transmitter (500) is turned off a shaped transition region (417') is generated at the beginning (162) of the transition region (411) followed by a stepped transition (415') at the end (3) of the transition region (411). The stepped transition (415 or 415') is generated by adjusting a voltage controlled attenuator (545) and the bias of a power amplifier (545) in the transmitter (500). The shaped transition (417 or 417') is generated by processing transmitted information through finite impulse response filters (507 or 509) before or after the time slot permitted for transmitting information.

IPC: F16K11/044
Filed: 1993-03-12
Abstract: VALVE AND OPERATOR THEREFOR                      Abstract of the Disclosure A valve including a valve member having two different stable positions,  and a valve operator for shifting the valve member between its two stable positions and holding the valve member in those positions.  The valve operator includes a shuttle moveable between two extreme positions corresponding to the two stable positions, respectively, of the valve member.  A first spring urges the shuttle toward one of its extreme positions and a second spring, stronger than the first spring, urges the shuttle toward the other of its extreme positions, these movements of the shuttle being transmitted to the valve member.   A device,  such as an electric  solenoid,   selectively  renders  the  second  spring ineffective with respect to the shuttle, so that when the second spring is ineffective the first spring causes the valve member to assume one of its stable positions, and when the second spring is not ineffective, the second spring causes the valve member to assume the other of its stable positions.

Filed: 1993-08-26
Abstract: ABSTRACT OF THE DISCLOSURE         A probe 10 and method for measuring a gaseous material, such as air, entrained in a solution (S) has a protective sheath member 14 having an ultrasonic transducer 18 encased therein and a reflecting member 42 spatially separated from the active area of face 20 of transducer 18.  Upon activation of transducer 18, ultrasonic waves are emitted from transducer 18 that reflect off the gaseous material in the form of bubbles 48 and reflecting member 42 thereby producing correspondingly associated backscattered signals therefrom.  Accordingly, the backscattered measurement is operative at low entrained air levels when only a few bubbles or gas 48 are present.  Scattering from reflecting member 42 is useful at higher entrained air levels, approaching foam.

Title: Control system using an adaptive neural network for target and path optimization for a multivariable, nonlinear process
Inventor: GRAETTINGER TIMOTHY J
IPC: G05B19/02
Filed: 1993-09-13
Abstract: ABSTRACT OF THE DISCLOSURE A control system having four major components: a target optimizer, a path optimizer, a neural network adaptation controller and a neural network.  In the target optimizer, the controlled variables are optimized to provide the most economically desirable outputs, subject to operating constraints.  Various manipulated variable and disturbance values are provided for modeling purposes.  The neural network receives as inputs a plurality of settings for each manipulated and disturbance variable.  For target optimization all the neural network input values are set equal to produce a steady state controlled variable value.  The entire process is repeated with differing manipulated variable values until an optimal solution develops.  The resulting target controlled and manipulated variable values are provided to the path optimizer to allow the manipulated variables to be adjusted to obtain the target output.   Various manipulated variable values are developed to model moves from current to desired values.  In this case trend indicating values of the manipulated and disturbance variables are provided to produce time varying values of the controlled variables.  The process is repeated until an optimal path is obtained, at which time the manipulated variable values are applied to the actual process.  On a periodic basis all of the disturbance, manipulated and controlled variables are sampled to find areas where the training of the neural network is sparse or where high dynamic conditions are indicated.  These values are added to the set of values used to train the neural network.
