Patent CA-2140065-A1 (CA)
Title: Solid state motor speed control
Inventor: NEIGER BENJAMIN
IPC: H02P25/14
Filed: 1995-01-12
Abstract: A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly, eliminating annoying buzzing noises that would otherwise be generated by the motor's windings. The invention provides for motor speed control with infinitely variable speed control settings. Rather than use triacs that generate RFI noise and cause motor windings to buzz due to their inherent avalanche switching, the invention utilizes power FETs or IGBTs to provide the switching function to control power delivery to the motor load.  The power switches are controlled by an oscillator that generates a pulse train with a duty cycle controllable by the user. A filter shapes this signal into a trapezoidal control signal that drives the gate input of the power FET or IGBT switch. A kick start circuit turns the motor on initially for two to three seconds to overcome the inertia of the motor and its load. A zero crossing detector prevents the motor from being turned on except at a zero crossing of the AC source to further reduce noise.

Title: Torque control device for rotary mine drilling machine
Inventor: MOORE RICHARD E
IPC: E21B17/07
Filed: 1995-02-15
Abstract: A device reducing the deleterious torque in a shock absorbing, rotary drive coupling unit used with a rotary mine drilling machine comprising: a drive plate connectable to a drive shaft of the rotary drilling machine, a driven plate connectable to a driven shaft which has a drill bit, a center portion for coupling the drive plate to the driven plate wherein the center portion includes a deformable shock, vibration and torque-absorbing member, and torque-relief means comprised of a first engagement member(s) connectable to the drive plate and a second engagement member(s) connectable to the driven plate. When the drill bit snags or jams during the operation of the rotary drilling machine, the torque-absorbing member deforms and absorbs some of the torque generated therefrom. When the torque generated from a snag or jam reaches a predetermined level, the engagement members of the drive plate physically contact the engagement member(s) of the driven plate causing the drive plate to directly drive the driven plate thus preventing any additional torque from being applied to the torque-absorbing member. An optional tensile-force relief member is provided which is mounted to the driven plate and is positioned above the drive plate. The drive plate physically contacts the tensile-force relief member in response to a predetermined amount of lifting force applied to the drive plate thereby limiting the distance the torque-absorbing member stretches when the torque control device is lifted from a blast hole.

Patent CA-2154252-A1 (CA)
Inventor: LIEDBERG NILS PER KE
IPC: H03K5/13
Filed: 1994-02-04
Abstract: The invention relates to a signal processing circuit for delaying a binary period input signal (S0). Three series-connected delay devices (D1-D3) produce output signals (S1-S3) which are delayed in relation to the input signal (S0). The delay of the delay devices (D1-D3) can be controlled to a very high degree of accuracy, in that the delay devices (D1-D3) include a plurality of mutually identical series-connected delay elements (20A-24A) which are manufactured at one and the same time by common process steps in one and the same semiconductor process. A control means (1) compares in a phase detector (2) the phase of the input signal (S0) with the phase of the output signal (S3) from the last delay device (D3), and on the basis thereof delivers control signals (V0-V4) to the delay devices. These control signals control the delay devices (D1-D3) in a manner such that an equal number of delay elements (20A-24A) will be activated in each of the delay devices (D1-D3), such that the delay devices will have mutually the same delay. The total delay between the input signal (S0) and the last output signal (S3) exceeds one-half but is less than one and a half periods of the input signal (S0) in a first regulating sequence, and the total delay reaches to one period of the input signal (S0) in a second regulating sequence.

Abstract: An automatic signal analyzing system for identification and analysis of facsimile signals in telephone signal transmission includes a switch unit, a service trunk, a signal identification trunk, a facsimile communication determination unit, and a control unit. The signal identification trunk restores a facsimile control signal from a modulated and encoded signal on the set speech path and performs collection of communication state information and detection of a start of facsimile communication on the basis of the restored facsimile control signal. The facsimile communication determination unit permits operation of the signal identification trunk when the classification result from the service trunk represents a type other than the voice signal and analyzes the communication state information from the signal identification trunk. The control unit performs switching/connection control of the switch unit, connects the service trunk and the signal identification trunk, both of which are in an idle state, to the set speech path upon setting of the speech path, disconnects the service trunk from the speech path when the classification result is output, and disconnects the signal identification trunk from the set speech path when the classification result from the service trunk represents the voice signal and when a call corresponding to the set speech path is ended.
Patent CA-2156209-A1 (CA)
Title: Electrical Isolation Device
Inventor: TACHICK HENRY N
IPC: H02H9/04
Filed: 1995-08-16
Abstract: An electrical isolation device is connected at input terminals in lines between a structure to be cathodically protected and a ground, or between two cathodically protected structures, to block selected low levels of DC voltage while freely conducting normal AC currents and all fault currents.  The device has two diode stacks, formed of layers, and the stacks are connected in parallel with one another in opposite polarity and in parallel with a capacitor across the input terminals of the device.  Each diode layer include a junction wafer and a conducting metal disk.  The layers in each stack are preferably pressed tightly together and to metal bus conductors by a clamp to maximize the contact of the diode layers to each other and to the conductors to minimize contact resistance.  AC currents are conducted (e.g., to ground) through the capacitor while low level DC voltages are blocked by the cumulative threshold voltages of the plural diode layers connected in series in each of the stacks.  When a large AC or DC fault occurs, the voltage across a stack exceeds the turn-on voltage of the stack so that fault currents are conducted to ground through the diode stacks.  The number of diodes in each stack may be selected to provide a continued cathodic protection voltage in the presence of large AC fault currents.  The diode stacks may also be connected together in a bridge structure to reduce the number of diodes required.

Abstract: A so-called "ELAN contronect network" is employed to interconnect sub-ELANs to form an ELAN. More specifically, the "ELAN contronect network" is a separate network for interconnecting the servers of the sub-ELANs, where a sub-ELAN is a part of an ELAN having its own LES and BUS that may also be configured as a stand-alone ELAN.  Each of the sub-ELANs is connected to the ELAN contronect network via a point-to-point connection-oriented connection, e. g., an asynchronous transfer mode (ATM) connection and the ELAN contronect network is configured to present itself to each of the servers of the sub-ELANs as clients thereof. In a particular embodiment of the invention, the ELAN contronect network includes an address server, a broadcast/route server, a configuration server, multimedia servers, and at least one LAN hub interconnected over a high-speed backbone. The address server contains an address data base for performing address resolution between the at least two addresses of each ELAN end-point in response to requests for such translations. The broadcast/route server receives data packets for broadcast to a different sub-ELAN from which the packets originated and broadcasts the received data packets to at least one other sub-ELAN. The broadcast/route server also recognizes that a packet which is a broadcast packet at layer 2 is actually a request for an address resolution at layer 3.If so, the broadcast/route server collaborates with the address server to perform the necessary address resolution and insures that a response is sent only to the client originating the request.
