Title: Radiographic film cassette with flexible foil cover
Inventor: STIEVENART EMILE F
IPC: G03B42/04
Filed: 1977-06-13
Granted: 1980-09-23
Abstract: ABSTRACT  OF  THE  DISCLOSURE      A radiographic cassette comprises a bottom and a cover capable of being locked together.  The cover has a part of its normally rigid structure replaced by a flexible foil which, when vacuum is applied to the interior of the cassette, exerts a pressure upon the film/screen combination contained within the latter.  In this way an intimate contact between the film and the screen is established and in the mean time the distance between the film/screen combination and the object to be radiographed is reduced to a minimum due to the small thickness of the foil.    The cassette may be used in the field of high-definition radiography especially for mammography.

Abstract: ABSTRACT:         By making the bridges in n few rows of apertures situated at the edge of the shadow mask of a colour display tube at least 20 % wider, the mask is not so readily des-troyed during drape drawing.         In addition, by keeping the width of the bridges in a row constant and increasing it regularly, preferably substantially linearly per row from a row through the centre of the shadow mask to a row at the edge of the shadow mask, a continuously varying brightness distribution is also obtained.         The reproduction mask for the manufacture of such a mask can be obtained in a simple manner by rotating the pattern of bridges between two exposures necessary for printing on photo-sensetive material and combination of the resulting copy with a pattern of stripes.

Granted: 1980-01-15
Abstract: Abstract of The Disclosure Ventilating apparatus having an exhaust hood for mounting in a room and normally above a stove, grill, or other apparatus from which fumes arise.  Ambient air from outside the room being ventilated is forced into an insulated intake chamber through a relatively narrow longitudinal slot at the bottom of the intake chamber, thence directed rear-wardly and upwardly across a fume collection chamber, through a grease filter, and into an exhaust chamber from which the fumes are exhausted to the atmosphere by a fan. The outside air is forced through the slot in a fast moving narrow stream to form an air curtain across the fume collec-tion chamber with minimal mixing of the fume laden air and the air curtain.  Tempered air is introduced into the room being ventilated adjacent the exhaust hood to provide a minimum influx of tempered air from the room being ventilated into the hood to prevent dissipation fumes into the room, and to facilitate collection of such fume laden air by the exhaust hood.
