Title: Apparatus for propelling one or two clay targets
Inventor: PATENAUDE STUART W
IPC: F41J9/30
Filed: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE   Clay target/pigeon throwing machines/traps used is the activity of sport shooting. The clay targets being circular and somewhat disc shaped. More particularly, the clay target throwing machine is adapted to optionally and automatically throw, simultaneously, two (2) targets. When the machine is set to throw one (1) target it is designed so that each successive target which is thrown is directed in a direction which is randomly generated so that the target direction is not predictable by the shooter as he/she is triggering the throw of the target by the machine. Additionally, a plurality of targets may be loaded into an indexing carousel which automatically indexes either one or two of the targets to the load position and stays in position while an "elevator" lowers the target or targets into the firing or throwing position. When in the dual throw mode, a device is provided which positions each of the clay targets one relative to the other to get consistent throws and to reduce breakage while the targets are being propelled by the throwing arm of the machine. The machine is operated by one bidirectional hydraulic motor which provides the indexing and the power to, in effect load the spring that provides the energy to the throwing arm to propel the target. A specially designed hydraulic piston assembly provides for the dampening of oscillations of the carousel when the carousel and the throwing assembly randomly position prior to the throwing of the target. The elevation angle of the target trajectory is adjustable with a cam and latching assembly.

Title: Method for burying optical waveguide paths
Inventor: BEGUIN ALAIN M J
IPC: G02B6/134
Filed: 1992-12-01
Abstract: Abstract of the Disclosure Optical waveguide paths are formed under the surface of a glass substrate by a method comprising (a) forming by ion-exchange a dopant ion path on a first substrate surface, (b) applying an electrode to the second surface, (c) contacting the first surface with a molten salt bath, and (d) applying an electrical field across the substrate to drive the dopant ions deeper into the substrate.  The current resulting from high fields can overheat the substrate, thereby causing substrate warping and burying of paths to uneven depths.  One aspect of the invention involves cooling the substrate by flowing the molten salt along the first surface of the substrate at a sufficient rate of flow to adequately decrease its temperature and by rapidly flowing the furnace atmosphere over the surface of the substrate.  A further aspect of the invention involves initially applying a voltage Vi across the substrate, allowing the current to increase to a predetermined level Im, and maintaining the flow of current at the predetermined level Im by decreasing the applied voltage at a rate necessarry to maintain the current at level Im.  The electrical field remains for a predetermined period of time to bury the ion path a predetermined depth.

Abstract: Un coussin thermique flexible permettant un transfert de chaleur à un membre d'une personne. Le coussin consiste en une enveloppe de tissu (préférablement du coton), enfermant une masse de grains de céréales, préférablement de l'avoine. Préférablement, le contenu en eau de l'avoine sera contrôlé de façon précise de façon à pouvoir évoluer à l'intérieur d'une fourchette de 9 à 14%  en poids du poids total de l'avoine. La quantité de grains d'avoine à l'intérieur de l'enveloppe de coton doit être telle qu'elle permette d'obtenir une distribution bien répartie d'avoine à l'intérieur de l'enceinte déterminée par l'enveloppe de coton, après sa déformation, de sorte que la formation localisée de vides sans grains de céréales soit sensiblement empêchée. Le coussin est soumis à un pré-chauffage pendant environ deux minutes, à  l'intérieur d'un four à micro-ondes, au degré maximum, pour pouvoir être utilisé. L'inertie thermique de l'avoine permettra alors une diffusion continue de chaleur sur le membre, pendant environ une demi-heure. Une autre application du coussin serait de le placer dans le congélateur pendant au moins quatre à six heures, afin de viser la résorption d'une région  démateuse d'un membre de mammifère par lente diffusion du froid.

Title: Method and electromagnetic security system for detection of protected objects in a surveillance zone
Inventor: GRANOVSKY MOISEI S
IPC: G08B13/24
Filed: 1993-03-17
Abstract: ABSTRACT            The transmitter antenna coils  (3,4)  provide an oscillatory electromagnetic field in a surveillance zone  (1) wherein a security tag of easily saturable magnetic material originates a  tag  signal.    The  original  tag  signal  deteated by  the receiver  antenna  coils  (6,7)  is  modified  to  obtain predetermined characteristics of an AC-pulse.   The modified tag signals are further processed in a signal processor (18) by  methods  of  synahronous  deteation  and  synchronous accumulation which not only increase a signal to noise ratio but also provide rejection of external periodic noises.   The controller  114)  provides  a  time-domain  blanking  for  the cyalic operation of the system.   The interrogation field is periodically made weaker, which allows to separate true tag signals from those originated by other magnetizable objects.          The noise level is also determined periodically during time intervals in which no tag signal can possibly exist.   This noise level is used as a dynamic reference which effectively prevents false alarms. if at the end of every surveillance cycle predetermined conditions are met a decision regarding an alarm is made.   46 Claims, 18 Drawing Figures

Abstract: Fuel is burned in accordance with a burning method and apparatus in two stages (62,64) and in the presence of first and second oxygen-containing gases, respectively. The second oxygen-containing gas (B) has a higher concentration of oxygen than the first oxygen-containing gas. The fuel stream is burned in a first (62) of the two stages at a first equivalence ratio sufficiently greater than 1.0, so that thermal NOx formation is inhibited, a more heat transfer effective luminous flame is achieved and a combustible mixture comprising unburned and partially oxidised fuel and fuel radicals is are produced for combustion in the second (64) of the two stages. The combustible mixture is burned in the second of the two stages at an equivalence ratio of no greater than about 1.0 so that maximum heat is transferred to the first of the two stages to stabilise combustion therein, and the fuel radicals are sufficiently oxidised by the second oxygen-containing gas to inhibit formation of prompt NOx. <IMAGE>

Patent CA-2097198-A1 (CA)
Inventor: SIREVAG GUNNAR
IPC: B09B1/00
Filed: 1991-11-20
Abstract: The present invention relates to a method for treating drill cuttings during oil and gas drilling, in particular in connection with oil and gas wells below water. This invention aims at a secure and permanent deposition of drill cuttings without risking environmental pollution. This invention is based on the philosophy that there is made a dispersion or emulsion of drill cuttings in water, as the particles of drill cuttings, including all present contamination, are disintegrated to obtain particles being so small that they may be dispersed in a relatively small amount of water. As no particle has a size above a predetermined tiny value, this dispersion may be pumped into most existing sub-sea structures and are thus permanently disposed of. The method is based on a continuous crushing and cleaning process, preferably including several stages, and where the process comprises several feedback paths and circulating loops, resulting in the fact that portions of the treated material run through the process several times until the desired, stable dispersion has been reached.

Abstract: A control  voltage  coarse adjustment  circuit including a  D/A converter voltage generator is provided on a load side of a capacitor in a  loop filter included in  a phase  locked  loop.       For this  structure,  a coarsely adjusted voltage  is generated to be added to a voltage which is  generated by the capacitor of the loop filter  for   the  switch-over  of   channels  during  a communication frame.         The added voltages  are applied  to a  voltage controlled  oscillator to  change  a frequency  for  the switch-over of  channels.      Consequently, the  charge and discharge  of the  capacitor  is  carried out  in  a short time  to  suppress  the  influence  of  dielectric absorption current.    Thus,  the intermittent operation of the phase locked  loop in which the phase locked loop is  closed and opened intermittently is  carried out for the saving of electric power consumption, and a  carrier frequency is stabilized  in the open  phase locked  loop by an  electric charge voltage  of the  capacitor in the loop filter.
