Inventor: FLEMING JOHN STUART
IPC: F24C3/00
Filed: 1996-09-26
Abstract: This invention provides a flammable fluid fuelled heater providing a direct opening into the primary combustion chamber to provide an unobstructed view of the fire. Any circulating means such as a fan may be provided adjacent the opening so as to provide an air curtain across the opening. This may limit the flow of air through the opening to reduce overall throughput as well as reducing spillage out the opening.

Inventor: KRANTZ LEONARD A
IPC: H01R24/56
Filed: 1996-10-17
Abstract: A triax cable contact provides improved high frequency performance by terminating the outer screen of the cable to an outer contact arranged to engage a ground clip in the connector and thereby ground the outer screen to the shell of the connector rather than directly to a corresponding outer contact of a mating triax contact. This permits the distance between the inner and intermediate contacts to be increased without increasing the outer diameter of the contact.

Patent CA-2198193-A1 (CA)
Inventor: PEITZ WOLFGANG
IPC: F21S8/10
Filed: 1997-02-21
Abstract: To provide for improved light distribution of a vehicular headlight furnishing both depressed-beam and high-beam illumination, a shadow cap (9, 25) partly surrounds a main light source located in a reflector (2) which has two segments ( 14, 15 ) of different contours. The first one (14) of the reflector segments is optically associated with the main light source furnishing depressed-beam illumination, and this segment has a free-formed surface reflection contour. A second segment of the reflector is optically associated with an auxiliary light source (8, 18) which is shaded by a shadow cap. The shadow cap (9, 25 ) provides a shadow angle of between 100° and 140° with respect to light emitted from the main light source (7) to define a shadow zone (12) and a light zone (13) on the reflector. The shadow cap is shaped and positioned with respect to the auxiliary light source such that the auxiliary light source is located within the shadow zone (12). The auxiliary light source is located by an offset of between 0.25 and 2 tunes below the optical axis (A) of the reflector, and the spatial distribution of the segments is such that the reflector is associated with a light zone and a shadow zone, respectively, as formed by the shadow cap. For high-beam illumination, both the auxiliary light source and the main light source, typically filaments of a halogen incandescent lamp, are energized, so that the respective illuminations are superposed, providing spread-out illumination from the main light source (7) and somewhat diffused spread illumination as well as a concentrated beam from the auxiliary light source (8, 18).

IPC: B21D37/16
Filed: 1995-08-16
Abstract: A bodymaker (15) that transforms shallow metal cups (16) in elongated can bodies includes a reciprocated ram (20) which, during its forward stroke, drives the cups through a set of graduated circular dies (22). Ring-shaped wipers (83, 84, 85) engage the outer cylinder surface (70) of the ram and are arranged so that a first of the wipers scrapes tool coolant from the ram as the latter moves rearward and a second of the wipers scrapes hydraulic bearing fluid from the ram as the latter moves forward. The wipers are provided with flexible flaps (89) that are in relatively low pressure frictional engagement with the ram resulting in only a very low temperature rise for the wipers to increase operating life thereof at production rates of approximately 400 per minute for cans of 2.5 inch diameter.

Title: Versatile multipoint video composition and bridging system
Inventor: KUMAR ARUN
IPC: H04N21/2343
Filed: 1995-09-18
Abstract: A flexible multipoint composition and bridging system is provided for video signal composition and bridging of a plurality of geographically dispersed locations. The system includes a centrally located bridging unit (101) that receives video, audio and data signal substreams from each of the remote locations. Based on the data substreams from each location, the bridging unit (101) resizes, cuts and pastes the various images into separate video montage images for display at each of the locations. The system enables users to optionally display video images or signals from one or more of the other locations within separate display windows at their respective terminals. The display windows can be zoomed, panned, scaled, translated, and partially or wholly occluded depending on a user's preferences or needs. The video images may be composed in signal space or entirely in transform space. Further, the flexible multipoint bridging system may be used for various applications, including video conferencing and broadcasting.

Title: Method for Azimuth Scaling of Sar Data and Highly Accurate Processor for Two-Dimensional Processing of ScanSar Data
Inventor: MOREIRA ALBERTO
IPC: G01S13/90
Filed: 1997-03-12
Abstract: In a method for azimuth scaling of SAR data without interpolation,  SAR raw data in azimuth are multiplied with a phase function H5(fa;rO), where fa denotes the azimuth frequency and rO denotes the range to a target point. An azimuth modulation of the SAR data is subsequently adapted with the phase function H5(fa;rO) to that of a reference range, in a manner so that the azimuth  modulation  no  longer  depends  on  the  range  and  is transferred into a pure quadratic phase modulation in order to attain an azimuth processing with a very high phase accuracy, by using deramping with an exactly linear frequency modulation and azimuth FFT.
Patent CA-2200667-A1 (CA)

IPC: G01N21/31
Filed: 1997-03-21
Abstract: A metal vapor 12 passing through a guide duct 13 from a vapor source 10 to a steel strip 1 is sampled through a takeoff pipe 14 to a measuring chamber 15. The metal vapor is irradiated with a measuring beam 20 in the chamber 15, to detect the absorbance of luminous energy in the metal vapor. The detected value of absorbance is used for the quantitative calculation of the metal vapor 12 passing through the guide duct 13, and the opening ratio of a shutter 17provided in the guide duct 13 is adjusted on the basis of the calculation result so as to control the flow amount of the metal vapor 12 passing through the guide duct 13.  In the case where a large amount of the metal vapor 12 passes through the guide duct 13, the amount of the metal vapor 12 reaching the measuring beam 20 is reduced by partially discharging the metal vapor 12 from the measuring chamber 15. Since the deposition amount of a plating metal is directly controlled in response to the amount of the metal vapor12 passing through the guide duct 13, the amount of a deposited plating layer is controlled with high accuracy and with a quick response time in a continuous vapor deposition coating line.

Abstract: L'invention concerne des cellules mésencéphaliques porcines ainsi que des procédés utilisant ces cellules pour traiter des déficiences neurologiques dues à une neurodégénérescence. Les cellules mésencéphaliques porcines peuvent être modifiées afin de les rendre appropriées à une transplantation chez un sujet xénogénique, tel qu'un être humain. Par exemple, les cellules mésencéphaliques porcines peuvent être modifiées de sorte qu'un antigène (par exemple un antigène MHC de la classe I) sur la surface de la cellule qui est capable de stimuler une réponse immune contre la cellule chez un sujet xénogénique, soit transformé (par exemple par contact avec un anticorps anti-MHC de la classe I, ou un fragment ou un dérivé de cet anticorps) afin d'empêcher le rejet de la cellule lorsqu'elle est introduite dans le sujet. Dans un mode de réalisation, les cellules mésencéphaliques porcines sont obtenues à partir d'un porc qui ne contient pas d'organismes ou de substances pouvant transmettre une infection ou une maladie au sujet receveur. Les cellules mésencéphaliques porcines de la présente invention peuvent être utilisées pour traiter des déficiences neurologiques dues à une neurodégénérescence du cerveau d'un sujet xénogénique (par exemple un être humain atteint d'épilepsie, d'un traumatisme crânien, d'apoplexie, de sclérose latérale amyotrophique, de la maladie de Parkinson, de la maladie d'Alzheimer, ou de la maladie d'Huntington) par introduction des cellules en question dans le cerveau du sujet.
