Patent CA-2085048-A1 (CA)
Inventor: DOWNS ROBERT W
IPC: G01V3/10
Filed: 1992-12-10
Abstract: The apparatus of the invention is a segmented pig body having an electrical instrumentation subassembly mounted thereto. The subassembly consists of a plurality sensors for electromagnetically coupling to the inner surface of the pipeline, each of which generates a signal that varies as the localized relative permeability of the pipeline metal; an odometer assembly for generating correlating data; and an instrument for recording the signal and data for later analysis. The method of the invention comprises passing the pig through the pipeline while it is electromagnetically coupled by the sensors to the inner surface of the pipeline.      During the pass, signals varying with the localized magnetic permeability of the pipeline wall acid correlative data are generated and recorded. After the pass, the correlative data is used to correlate the signals to wall locations to locate stress occurrences.

Title: Automatic level control circuit for dual mode analog/digital cellular telephone
Inventor: DURTLER WILLEM G
IPC: H03G3/20
Filed: 1993-02-04
Abstract: An automatic level control circuit for cellular telephone transmitters which is compatible with both existing analog cellular service and. expected next generation digital TDMA service. The circuit automatically and dynamically changes modes to maintain communication when a mobile subscriber moves from one type of service to another. In a first mode of operation, which is compatible with existing analog cellular service, the circuit provides a closed loop negative feedback circuit which produces a control signal for continuously controlling the output power level of the transmitter amplifier. In a second mode of operation, which is compatible with proposed digital TDMA service, the circuit operates to alternately close the negative feedback loop during the periods when the transmitter is permitted to transmit (assigned TDMA frames) and open the loop during other periods when the transmitter is turned off. When the loop is opened, the invention temporarily stores the magnitude of the control signal. This stored value is subsequently used to quickly restore the amplifier to its assigned power level during successive frames when the loop is again closed for burst transmission.

Filed: 1992-09-30
Abstract: A method (215) of converting a current control channel for use as a communication (voice/data) channel, in order to main-tain a predetermined level of service in a radio communications system, employs a central controller (101) to allocate a limited number of communication channels among a plurality of subscriber units (108-112). After receiving (203) a request for a commu-nication channel from one of a plurality of subscriber units (108-112), the controller (101) determines (205) whether all of the communication channels are busy. The controller then temporarily converts (215) the current control channel to a communication channel.

A stationary side wall is erected along the side edge of the other end of the slat of the sliding surface section.  Cooperative action between the selected tire and the side wall causes frictional force on unwanted tires to cause them to fall back to the supply of tires.

Patent CA-2109448-A1 (CA)
Inventor: BRIGGS EUGENE C
IPC: F23K5/14
Filed: 1993-10-28
Abstract: An oil-burning furnace including a combustion zone and a nozzle block assembly through which oil and pressurized air are introduced  into the combustion  zone utilizes  an  oil pump of trochoidal design for delivering oil to the combustion zone at a metered rate and a purge control for withdrawing oil from the nozzle block assembly upon shut down of the furnace operation.  The flow rate at which the oil pump delivers the oil to the nozzle block  assembly is relatively constant regardless of the weight or viscosity of the oil burned by the furnace, and the purge control cooperates with an air compressor used for delivering air, under pressure, to the nozzle block assembly and includes an expandable zone for extracting oil from the nozzle block assembly upon a de-energizing of the air compressor.  The nozzle  block assembly also includes a block providing an air passageway through which air is pumped from the air compressor into the combustion zone and an electric heating element disposed within the air passageway for heating air routed therethrough.  Thermostats mounted within the nozzle assembly block ensure that the block is maintained within a preselected temperature range from the outset of furnace operation.

Title: Control system employing a data model in a network environment
Inventor: GARD BENGT E I
IPC: H04L12/24
Filed: 1992-08-18
Abstract: A communication network control system includes facilities for data driven control of components attached to the network. The network has an overall control function (74) and each component (58, 60, 62, 64) has an individual control function (66, 68, 70, 72).  Common component control functions (76) can be controlled via the overall control function (74) straight away. Uncommon component control functions are controlled via translation of subfunctions within the overall control function (74). Such translations are effected as required based upon information regarding individual component needs, which information is stored in a data model (86) where it may be accessed and subsequently interpreted as part of the overall control function (74).
