Patent CA-2054156-A1 (CA)
Title: Low torque centralizer
Inventor: KELLER STUART R
IPC: E21B17/10
Filed: 1991-10-24
Abstract: ABSTRACT OF THE DISCLOSURE     An improvement to a centralizer that may reduce the torque required to rotate a casing in a borehole during primary cementing is disclosed.  In a first embodiment, the improvement is adapted to a bow spring type centralizer having intermediate fixed and slidable sleeves with each sleeve circumscribed by an end band.          The end bands are connected to each other by a plurality of bow springs.  The improvement includes interposing a sleeve bearing between each end band and its respective intermediate sleeve.  The sleeve bearings may be attached to the intermediate sleeves to permit their rotation with the casing relative to the stationary end bands and bow springs.  Alternatively, the intermediate sleeves may be eliminated and the sleeve bearings interposed directly between the outer surface of the casing and inner surfaces of their respective end bands.

Abstract: ABSTRACT OF THE DISCLOSURE       A TDMA (Time Division Multiple Access) radio communication apparatus having a receive frequency mixer and a transmit frequency mixer. The receive and transmit frequency mixers are implemented by a single frequency mixer. Signal selecting means is connected to each of the input and output of the single frequency mixer for separating a high frequency signal and an intermediate frequency (IF) signal.  When a received high frequency signal is fed from a receive high frequency filter to the mixer, the resulting IF signal from the mixer is delivered to a demodulator. When an IF signal to be transmitted is fed from a modulator to the mixer, the resulting high frequency signal from the mixer is applied to a transmit high frequency filter. The received IF signal and the IF signal to be transmitted are prevented from leaking into the modulator and the demodulator, respectively.

Title: Automotive engine
Inventor: STONE CYRIL O
IPC: F01P3/00
Filed: 1992-09-10
Abstract: ABSTRACT         The engine for which I claim to be the sole inventor is much lighter and smaller than any of the usual piston engines in use in most vehicles today.  Present engines have become so complicated and full of expensive materials and have required so much complex matching that they are more of a curse than a blessing.  The exhaust gases from present cars is causing people all sorts of illnesses.  It is only about one tenth the weight of piston engines and has no complicated parts that are so accurately and expensively machined and should have far less friction than these engines.  In this way alone it performs far more efficiently than other automotive engines and since it is continually washed with soap and water is is quieter and less polluting than these engines.  No expensive alloys are used in my engine and no oil is needed since no parts rub or slide against any others.  I expect is to have a long life and it will have few parts which should ever require repairs or re-placement.

Abstract: Apparatus  for  detecting  and  measuring  relative concentrations of pollutants such as HC, CO and CO2 in the exhaust emissions from passing vehicles includes an infrared (IR) beam  source  for  directing  an  IR  beam  through  a  vehicle's exhaust plume and a detector disposed on one side of a roadway and a lateral transfer mirror (LTM) disposed on the other side of the roadway for  lateral reflecting of the IR beam back through the vehicle's exhaust plume and onto the detector.  The LTM allows for close spacing and precise alignment between the emitted and reflected beam paths and permits the IR beam source and detector to be disposed in a single module.   Compensation for  temperature  variation  in  the  temperature-sensitive  IR detectors  as  well  as  for  a  range  of  vehicle  operating conditions  is  provided  by  adjustable,  computer-controlled potentiometers,  while audio and/or visible light feedback of the detected IR signal allows a single operator to precisely align the optical components of the apparatus.  The IR detector module includes a rotating mirror arrangement for directing the reflected IR beam in a pulsed manner onto a plurality of spaced detector  elements,  each  adapted  for  detecting  a  specific pollutant,  with  the detector  elements  calibrated with  each detected IR pulse to reduce errors arising from circuit drift.
