Title: Clock recovery for serial data communications system
Inventor: DAVIES DAVID C
IPC: H04L7/033
Filed: 1990-06-27
Abstract: CLOCK RECOVERY FOR SERIAL DATA COMMUNICATIONS SYSTEM            ABSTRACT OF THE DISCLOSURE   In a serial data communications system, an embedded clock is recovered from a data signal by incrementally controlling the frequency (thus phase) of a voltage-controlled oscillator in response to the difference in phase between the incoming data signal and the clock oscillator output. A transition of the data signal is detected and used to initiate a control pulse which is terminated upon the next transition in the clock oscillator output. A reference pulse is also generated which has a width about equal to a half cycle of the clock. These pulses are used to generate the voltage control for the oscillator, so that the phase relationship varies to seek an equilibrium where the pulses are of equal width and the transitions of the clock are at midpoint of potential transitions of the data signal. The control can tolerate relatively long periods where there is no transition of the data signal. The control circuitry includes a counter for counting transitions of the clock to inhibit another detect operation from starting until three transitions after one has begun.

Patent CA-2027073-A1 (CA)
IPC: B09C1/00
Filed: 1990-10-05
Abstract: ABSTRACT A method for disposing by incineration of oil contaminated waste material after removal of solids of various kinds by performing multiple steps in its handling wherein the composite material is first subjected to a first classification step for extracting a high percentage of contaminant free material.  After subjecting the material to a second classification cyclone where the gases that are used to transport the ground matter can be separated while the solids are subjected to classification by the use of a vibratory screen where the paper, fluffy waste, and similar material can be separated from the smaller and harder particulate components.  The separated components are subjected to individual impact grinding steps prior to being recombined in the combustor where incineration takes place.  The gases separated in the cyclone step for moving the residue of material into an incinerating combustor, and ambient air is delivered to the incinerator for establishing sufficient oxygen to support combustion at a temperature that will sanitize and destroy odors in the waste material and after the sanitizing step in the incinerator, the gases are exhausted through suitable heat exchangers and filtering medium while the residue material is fused at high temperature into stable pellet form.

Abstract: Précis La présente invention est un nouveau concept de propulsion aérodynamiquenécessitant deux corps. Le premier est axisymétrique tournant sur son axe et ledeuxième est un corps fixe, dirigeable et pouvant épouser une partie de la surface extérieure du corps précédent (Ex. cône et demi-cône creux). Avec un ordre de grandeur de quelques millimètres les séparant, les deux corps appartiennent a unmême système. Ce principe de propulsion est différent des autres de part son angle d'attaque inexistant. De plus, il permet une force de propulsion perpendiculaire à la surface cachée du premier corps (surface déterminée par l'utilisateur) ce qui donne la possibilité de décider de la direction du déplacement. Et finalement ce concept a un rendement supérieur à 1 lors d'un mouvement horizontal du système. En ce quia trait a l'utilité, ce principe s'applique à tout appareil propulsée par une force éolienne.

Title: Process for the hydrogenation of a carbon containing feedstock, in particular coal and/or heavy oil
Inventor: WUERFEL HELMUT
IPC: C10G47/36
Filed: 1990-12-20
Abstract: ABSTRACT           A process for the hydrogenation of a carbon compound containing feedstock,  such as coal and/or heavy oil,   by reaction with hydrogen  at elevated pressure and temperature in a reactor.  The feedstock is introduced under pressure into the upper part of the reactor and passes downwardly through the latter, first through a heating or prereaction zone and then through a main reaction  zone,   while  the required hydrogen passes upwardly in countercurrent  through the  reactor.      The  hydrogenation  products  are withdrawn at the top and the residue is withdrawn at the lower part of the reactor.   Part of the contents of the reactor,  which flows downwardly through the reactor is continuously recirculated from the main reaction zone into the heating or prereaction zone. The recirculation of  the  contents  of  the reactor takes place by means of an agitator provided for that purpose.  The feedstock fed under pressure is divided into  two  components  depending  on  the  required temperature.   One component flow is introduced into the  heating  zone  and the  second  component  is introduced into the main reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE A fibrous electrically-conductive filler comprises fibrous aluminum borate as a core material and a layer of a electrically-conductive substance which covers the core material or comprises fibrous aluminum borate as a core material, a layer of titanium oxide which covers the fibrous aluminum borate and a layer of a electrically-conductive substance which covers the titanium oxide layer. The fibrous electrically-conductive filler can be prepared by a process comprising the step of directly forming a layer of a electrically-conductive substance doped with antimony or fluorine on the surface of fibrous aluminum borate, or the steps of forming, on the surface of the fibrous aluminum borate, an intermediate layer of titanium oxide in an amount ranging from 2 to 50% by weight on the basis of the weight of the fibrous aluminum borate and then forming a layer of a electrically-conductive substance doped with antimony or fluorine on the surface of fibrous aluminum borate. The filler has a low volume specific resistivity and is substantially excellent in electrical conductivity-imparting effect per unit weight thereof when it is added to a basic material such as a resin.          The electrically-conductive substance coated on the filler surface is not peeled off and hence the filler does not cause loss of the electrical conductivity when it is incorporated into a basic material such as paper, a plastic, a rubber, a resin or a paint. The filler per se is white or transparent and, therefore, the color tone of such a basic material may be arbitrarily changed by the addition of a coloring agent.

Abstract: DEMAND APNEA CONTROL              ABSTRACT OF THE DISCLOSURE     An apparatus and method for the control of both central and obstructive sleep apnea using electrical stimulation on a demand basis.   Implantable sensors monitor  the  respiration  cycle  and  determine  the occurrence of apnea events.  Central apnea is sensed by the passage of an escape interval of time without the sensing  of  an  inspiratory  event  and  a  concurrent decrease in blood oxygen saturation.  Obstructive sleep apnea is sensed as an abnormal pressure differential across  the  airway.    The  diaphragm  is  electrically stimulated  upon  sensing  of  central  apnea.     The musculature  of  the  upper  airway  is  electrically stimulated upon sensing of an occurrence of obstructive sleep  apnea.    Stimulation  of  the  upper  airway  is provided whenever central apnea is sensed.
