Patent CA-2135807-A1 (CA)
Inventor: CORABATIR KAYA
IPC: F24F11/75
Filed: 1994-11-15
Abstract: ABSTRACT   An apparatus for temperature control in a room by adjusting supply air flow rate in response to a room thermostat in a ducted air conditioning system where a plurality of rooms are supplied by a single air handling unit. The apparatus may be installed in a plenum which is directly mounted on an air supply terminal. The apparatus is connected to a main supply duct with a branch duct, and as a result of its favourable geometry and throttling method, operates at low noise levels. The apparatus employs high aspect ratio converging nozzles to allow incoming air accelerate into a thin sheet of high velocity air stream. Air flow rate is adjusted simply by changing the nozzle area. This high velocity air stream entrains surrounding air within the plenum and slows down. Its energy is dissipated through friction with acoustically lined plenum walls. In this process, little noise generated. The apparatus, due to its special shape, allows accurate measurement of air flow rate. The apparatus incorporates a control system for adjusting the air flow rate in response to a room thermostat. The control system may further comprise means for controlling supplementary heaters or heating valves.

Title: Power laser system
Inventor: DAS PALASH PARIJAT
IPC: H01S3/04
Filed: 1993-11-09
Abstract: A housing in a laser system encloses a cathode and a displaced anode and gases ionizable and reactive chemically when a voltage pulse produces a cathode-anode electrical discharge. Moving air cools the components (capacitors, thyratron and triggering circuitry) for producing the voltage pulses. The laser gas temperature is continuously regulated at a particular value whether or note there is an electrical discharge. The concentration of one of the gases in the chamber is regulated to values alternately on opposite sides of an optimal value to provide an optimal energy in each chemical reaction of the gases. The gases are recirculated as by a fan driven on a shaft by a pair of motors and are filtered during recirculation. The shaft speed is regulated at a particular value and the motor currents are regulated to be equal. Any ozone formed in a compartment holding the high voltage terminals is purged by passing a neutral gas (nitrogen) through the compartment to the atmosphere. The neutral gas is passed into the housing through a hose which also holds a high voltage wire in insulated relationship to other electrical components. A collar arrangement at one wire end provides for the introduction of voltage from the collar to the anode of the thyratron with the hose coupled to the housing and grounds the collar with the wire decoupled from the housing. The different high voltage components are sequentially tested for their operability by a system and method unique to this invention.

Patent CA-2152102-A1 (CA)
Inventor: CUFFE JOHN M
IPC: G01N29/27
Filed: 1995-06-19
Abstract: Apparatus (10) for measuring the physical properties of an tube (T) or similar object using an ultrasonic testing method. A pulse generator (12) generates an electrical pulse having a predetermined set of characteristics. Transducers (20a, 20b) simultaneously convert the pulse to an ultrasonic waveform (W) and propagate the waveform at the tube from at least two different directions. The transducers then convert echoes (E1-E3) from the tube into electrical response pulses. Another transducer (24a) propagates a similar waveform at a reference object (B) and converts an echo from the reference object into a reference electrical response pulse. The reference response pulse is then combined with each of the other response pulses. Separate receivers (28a, 28b) receive the respective combined response pulses and converts them to digital data stored in a memory (32). A multi-channel processor (36) simultaneously, separately reconstructs each combined waveform and determines from each separate reconstruction a value representing a physical characteristic of the tube. Processing first involves performing a "real time" evaluation the combined waveform to determine if it meets threshold criteria. If so, the multi-channel processor performs linear interpolation and finite impulse responses on the digital data to precisely measure time of flight (TOF) values. A separate processor (54) includes a computing section (60) for mathematically combining the respective TOF values derived from the separate reconstructions to ascertain yet other physical characteristic values of the tube. Additionally, this processor includes a section (62) for comparing each physical characteristic value with a predetermined set of limits for each of the values to determine if the measured values fall within the limits. The results of the comparison can be displayed to an operator, and a permanent record of the values is also made.

IPC: A61K48/00
Filed: 1994-07-26
Abstract: L'invention se rapporte à une stratégie thérapeutique impliquant (1) l'identification d'allèles alternatifs de gènes codant pour des protéines vitales pour la viabilité ou à la croissance cellulaire et de la perte d'un de ces allèles dans des cellules cancéreuses due à une perte d'hétérozygosité (LOH) et (2) le développement d'inhibiteurs présentant une spécificité élevée pour l'allèle alternatif unique restant du gène vital retenu par la cellule cancéreuse après que la LOH a eu lieu. Les inhibiteurs de l'invention sont spécifiques d'un allèle alternatif d'un gène codant pour une protéine vitale pour la vitalité ou la croissance cellulaire. Le gène ciblé comprend deux alléles alternatifs, les inhibiteurs de l'invention ne bloquant qu'un des deux allèles alternatifs encore présents dans les cellules cancéreuses. L'expression à l'inhibiteur inhibe ou détruit les cellules cancéreuses ayant subi une LOH. Une protéine est encore susceptible d'être exprimée dans les cellules normales exposées à l'inhibiteur par l'allèle alternatif non bloqué. Cet effet différentiel de l'inhibiteur par rapport aux cellules cancéreuses et aux cellules normales explique l'indice thérapeutique élevé des inhibiteurs de l'invention lorsqu'ils sont utilisés comme agents antinéoplasiques.

Abstract: Image compositing apparatus and methodology for the creation, in a defined volume of three-dimensional space, of a composite organization of plural images/visual phenomena, including at least one projected real image (104), displayed in formats including (a) front-to-rear, (b) side-by-side and (c) overlapping and intersecting, adjacency. The apparatus incorporates different unique arrangements of visual sources (110, 112), and optical elements including concave refloc-tors (114), beam splitters (116) and image-forming/image transmissive scrim screen structures (334). In one important modification of the system, which does not necessarily re-quire compositing, a projected real image is derived from an image-producing data stream containing three-dimensional image cues selected from the group consisting of shading occlusion, perspective, motion parallax, size vs. depth, light (chroma value) vs. depth and definition vs. depth. In a fur-ther important modification of the invention, a system (620) is proposed which allows a viewer/user to interact directly with a projected real image, in a manner allowing the ma-nipulation of one or more characteristics or aspects of the image.
