Patent CA-2018970-A1 (CA)
Title: Rockbolt load indicator
Inventor: FRIESEN GORDON R
IPC: E21D21/02
Filed: 1990-06-13
Abstract: ABSTRACT      This invention is a system for monitoring changes in load on mechanical  rockbolts  used  for  ground  support  in underground mines.  It is intended to serve  as a safety device  to provide warning  of  stress  changes  or  impending  ground  failure.  It consists of  a series of  Belleville washers,  or disc  springs, mounted  on  the   protruding  end  of   a  rockbolt.  A   linear relationship  exists  between  the amount  of  flattening  of the Belleville washers and the load change. The unique aspect of this system is the  device used to indicate the  amount of flattening, and hence, the load change. Two alternatives for  load indicators are  presented,  namely   RBM1  and  RBM2,  which   are  distinct variations on  the same principal  of reflecting a change  in the height of the stack of washers as the load changes. RBM1 uses the number of threads required to reset the spring-loaded device back to  its original position, to quantitatively measure load change. RBM2  is intended  to  qualitatively  reveal  that  changes  have occurred, to serve as a warning device.

Patent CA-2031934-A1 (CA)
Inventor: COLE GARY B
IPC: H04J3/06
Filed: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE      A system that provides a signal in an assigned time slot of a multi-time slot repetitive frame, the assigned time slot being determined by input data that changes only on occasion, includes a flywheel circuit for reducing the chance that intermittent errors in the data input may cause the signal to be provided in an incorrect time slot.  The flywheel circuit includes a time slot counter synchronized to provide a zero count during the assigned time slot and to initiate an output signal whenever the zero count occurs.  The timing of a particular count of the counter is compared to the timing of the signal from the system during each frame, and if the timing does not correspond in a predetermined manner for a predetermined number of consecutive frames, the counter is re-synchronized to the timing of the signal from the system.

Abstract: A supervisory circuit for optical repeaters has a selective decoder circuit for selecting and decoding either one of control signals for monitoring which are separated from individual transmission signals being propagated over the own channel and the other channel.          When noise ascribable to a fault occurs on the own channel, a signal path connecting to the selective decoder circuit for inputting a control signal from the own channel is interrupted.  Noise of this kind is detected in terms of an input signal level which does not lie in the frequency band of control signals.

Title: Method for detection of viral rna
Inventor: LIU JIANG J
IPC: C12Q1/68
Filed: 1991-03-22
Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a process for detecting an RNA virus in a sample, e.g. clinical, suspected of containing the virus.  The process comprises treating the sample with heat for denaturing protein coating the RNA in the presence of a non-proteinaceous RNase enzyme inhibitor such as diethylpyrocarbonate (DEPC).  RNA freed from the protein coat is protected from destructive RNase activity upon cooling of the sample by addition of a proteinaceous RNase inhibitor, such as RNadeTM or RNasinTM when the temperature of the sample is below the denaturation temperature for the inhibitor.  RNA can then be detected, for example by reverse transcription (RT) to form cDNA and then applying the polymerase chain reaction method to amplify the amount of cDNA to detectable levels.   Detection of cDNA so amplified confirms the presence of RNA virus in the initial clinical sample.

Abstract: COMPACT HIGH PERFORMANCE SCANNING APPARATUS            Abstract of the Disclosure A compact optical scanning apparatus includes a motor driven hollow drive shaft through which scanning light beams are projected.  A mirror mounted on one end of the drive member deflects the light beams to the side of the drive member, said light beams impinge on the interior surfaces of a conically shaped ring of mirrors.  The ring of mirrors will deflect the light beams downwardly towards a circular mirror mounted horizontally which reflects the light beams towards a ring of pattern forming mirrors mounted perpendicular to the circular mirror. The pattern forming mirrors will reflect the light beams through an aperture in the scanning apparatus in the form of a scanning pattern.  A gear mechanism mounted between the ring of mirrors and the drive shaft rotates the ring of mirrors in a direction opposite to that of the drive shaft.
