Granted: 1991-01-15
Abstract: Abstract A process is described for two-stage coprocessing of coal and a heavy hydrocarbon, such as bitumen from tar sands.  A slurry of the bitumen and coal is passed upwardly through a coal dissolving and hydrogenation zone and the top discharge from the coal dissolving zone, containing partially solubilized coal and ash, is passed through a confined hydrocracking zone.  The effluent emerging from the hydrocracking zone is sepa-rated into a gaseous stream containing a wide boiling range of material and a liquid stream containing heavy hydrocarbons.  This process permits maximum yields from both coal and bitumen, while suppressing coke formation during hydrocracking.

Title: Signal processing circuits
Inventor: TRETT JOHN
IPC: H03K17/16
Filed: 1987-02-05
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE         A detection system for a sliding lift or elevator door comprises at least two sensors for monitoring the door opening.  The sensors are arranged to detect the presence of moving irregular shape (e.g. the human form) in the doorway to reverse the opening action of the door or, if already open, to prevent the door from closing.  A signal compensation circuit is provided to process the output signals from the sensors in a sense to maintain the outputs equal under steady state conditions.  This is achieved by using the output of a first sensor as a quasi reference signal.  A comparator compares the output of a second sensor with a quasi reference signal and through a feedback loop modifies the output of the said second sensor in a sense to equal the output of the first sensor.  The feedback loop contains a delay circuit which is switchable between a long and a short delay.  for slow changes in the output of the second sensor the long delay is effective but for fast changes the delay circuit is switched to provide a short delay.          The compensation circuit is effectively desensitised against errors due to drift and other slow varying influences.
