Patent CA-2093180-A1 (CA)
Inventor: LYNCH R LARRY
IPC: B01F23/10
Filed: 1993-04-01
Abstract: The present invention provides a process for decreasing the relative humidity of a gaseous or vaporous process stream, while increasing the temperature thereof.  A preferred embodiment of the process of the present invention is implemented using a bleed valve, a positive displacement blower located downstream therefrom, and a control mechanism for opening and closing the bleed valve. When opened, the bleed valve preferably permits ambient air to admix with the gaseous process feed stream to form the blower feed stream.  Increased blower gas throughput results in a lower magnitude gas temperature increase across the blower.  The control mechanism used in the practice of the present invention involves monitoring the temperature of the blower effluent (or the gaseous feed to a downstream unit operation), and controlling operation of the bleed valve in accordance with that temperature reading.

Abstract: A plurality of frames associated with sequences of video source material representing a series of scene changes are digitized.  A computerized process  analyzes the digitized information and identifies one or more frames of the source material associated with and representative of each such scene change and/or sequence. The representative frames are displayed. A selected frame from the display will thereby cause automatic selection and association of a sequence of frames comprising a corresponding video sequence from which the  frame  was  selected  for  subsequent  playback.  In  a preferred embodiment,  the  entirety of  the  representative frames or a subset thereof are specified and ordered. The order  of  the  corresponding  frames  of  video  segments  or scenes corresponding  to  each  such  selected  and  ordered representative frame are thereby automatically also ordered. Simplified video  editing  is  accomplished by manipulating these  representative  frames,   each  associated  with  a different scene or video sequence.

Patent CA-2099369-A1 (CA)
Title: Dynamic pulse control for fluoroscopy
Inventor: NIELDS MORGAN W
IPC: H05G1/26
Filed: 1991-12-23
Abstract: An apparatus and method for dynamically controlling the generation of radiation pulses during pulse-type fluoroscopic imaging.  Brightness of an image produced by a pulse (200) is detected (202), converted to a digital value (204) and compared to an acceptable predetermined value range (206, 208). If the brightness is not acceptable, the pulse rate is reset (212) to a predetermined, relatively fast rate and the energy level for the next pulse adjusted up or down (210) to increase or decrease the brightness as necessary. Once the brightness is found to be acceptable, the pulse rate is returned to the original pulse rate (218). If it is determined that motion is occurring (214, 216), the pulse rate will increase (212) to the relatively fast predetermined pulse rate to provide substantially real-time imaging. If the brightness becomes unacceptable (208) for a pulse during the period of motion, the energy level for the subsequent pulse will be adjusted (210). This technique of pulse control effectively reduces patient dosage and operator exposure to radiation, provides substantially real-time imaging during periods of relative motion and provides rapid image stabilization times.

Abstract: La valve  (10)  comprend un boîtier  (20) muni d'une entrée d'air (23) fixée à l'extrémité d'un conduit d'air vicié (60) d'un appareil ménager, et d'une sortie d'air (24) vers l'extérieur. La valve (10) comprend un épaulement (41) relié hermétiquement à l'entré d'air (23). Une balle (42) logée dans le boîtier (20) s'y déplace entre une première et une deuxième position en suivant un guide (43). Lorsqu'aucun écoulement d'air ne provient du conduit (60), la balle (42) s'appuie hermétiquement et par gravité contre l'épaulement (41)  afin de prévenir la pénétration d'air extérieur à l'intérieur du conduit sous l'effet de rafales de vent. L'épaulement (41) et la balle (42) peuvent être faits en un matériau isolant afin de diminuer la perte de chaleur par conduction  vers  l'extérieur  par  temps  froid.  Lorsque l'appareil ménager est en fonction, la balle (42) se déplace à la deuxième position sous l'effet de l'écoulement d'air vicié pour permettre son évacuation. Une fois que l'appareil est arrêté, la balle (42) retourne toute seule à la première position. La valve (10) peut avantageusement s'appliquer à toute  sortie  d'air  forcé  que  l'on  retrouve  sur  des appareils,  tels  les  sorties  d'air  de  sécheuses,  de ventilateurs de chambre de toilette, d'échangeurs d'air ou de hottes de cuisinière,  afin de remplacer les clapets pivotants conventionnels.

Filed: 1994-01-25
Abstract: PHASE SHIFT DEVICE USING VOLTAGE-CONTROLLABLE DIELECTRICS                   ABSTRACT OF THE DISCLOSURE    A length of strip transmission line uses two symmetri-cally spaced center conductors between two groundplanes These conductive strips produce an even-mode electric field between the two groundplanes when excited in-phase and an odd-mode electric field when excited in anti-phase rela-tionship.  For the latter case, the phase velocity of the odd-mode is significantly affected by the electric field in the gap region between the conducting strips.  By varying the relative dielectric constant of a material located in the gap region, e.g., by means of a voltage-controllable dielectric such as barium-titanate compositions, the phase velocity and,  hence,  the phase  shift of an RF signal propagating through the strip transmission medium can be controlled.

Abstract: In order to improve the productivity of pressure-resisting bottles by reducing the blow time from 4-5 seconds in a conventional bottle molding method to not more than 3 seconds, and mold pressure resisting bottles free from the occurrence of crazing and bottom-breakage, a biaxially stretched blow molded bottle (1) of a synthetic resin having a big foot type petaloid bottom is produced in a blow time of not more than 3 seconds, and after the product has been released from the mold, the bottom portion (3) has become not higher than 70°C, whereby the shortage of the capability of the metal mold of cooling the bottom portion (3) is supplemented.  This allows both the prevention of the irregular deformation of the central part (6) of the bottom portion, and the molding of the bottom portion (3) of high pressure resisting strength and mechanical strength with a sufficient height H of the central part (6) of the bottom portion ensured.
