Abstract: RCA 72,96 ABSTRACT OF THE DISCLOSURE In the novel method, the widths of the parallel luminescent stripes of a luminescent viewing screen are scanned by a beam of ultraviolet light whereby the stripes are excited to emit light along the path of scan. The emissions of the light in an identifying spectral band are sensed with respect to the position of the light beam on the screen and converted to a train of electrical signals.  Then, the average width of the stripes identified by the spectral band is calculated from the distance over which the intensi-ties of the signals are continuously above an assigned value.

Abstract: Abstract: -In single family house oil heating, it is common to recommend caulking of exterior cracks to minimise air infiltration or "air change". More recently, in attempts to improve furnace efficiency, stack dampers have been proposed, but have various disadvantages including illegality in many jurisdictions. In this invention, the oil burner (air inlet) is enclosed by a duct, at the side or end of which a damper hangs freely in a closed position. When the burner is not in operation, the enclosure and damper minimises the volume of air drawn through the burner etc, from within the house by chimney draft. When the burner is operating, the damper is opened by suction from the burner fan, permitting normal combustion air to enter the burner.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous loop transmitting winding assembly is disposed in one panel and a vertically oriented figure eight receiving coil winding assembly is disposed in a second panel, the two panels being mounted on pivots for swinging gate type movement straddling the pathway to be controlled by a magnetic surveillance system.  This arrangement confines the surveillance field to the pathway and tends to follow the passage of an object bearing a marker therealong.  No marker detecting backfield is generated.  Alternatively, one winding assembly is moveable while the other is stationary thereby similarly confining the field.         Special winding configurations are used to reduce interference from third harmonic signals produced in adjacent metallic counters.  The arrangement also imposes immunity to signals emanating from cash registers, motors and the like.         Door and single gate mounted magnetic and microwave surveillance systems are also disclosed.

Abstract: ABSTRACT        A METHOD OF RECOVERING VISCOUS OIL FROM A                  SUBTERRANEAN FORMATION          The vertical conformance of a steam drive process is improved by conducting the steam flood process in two stages.  In the first stage, steam is injected into the lower portion of the formation via an injection well and oil is recovered from the upper portion of the formation via a spaced apart production well.  Once there is a breakthrough of steam at the production well, injection of steam and production are terminated.  In the second stage, the roles of the injection well and production well are reversed.  A thermal recovery fluid comprising steam or hot water is injected into the lower portion of the formation via the production well and oil is recovered from the lower portion of the formation via the injection well until the oil recovered contains an unfavorable amount of steam or water.

Abstract: ABSTRACT A system for ultraviolet curing of ink on exteriors of articles such as plastic bottles employs a conveyor means to transport an upright row of bottles through an elongated curing station between opposing ultraviolet lamps while spinning the bottles about their axes.  The preferred means for spinning the bottles includes a fixed bar and a moving belt which frictionally engage the necks of the bottles and impart motion to them due to the relative motion of the belt with respect to the fixed bar.  The apparatus is adjustable to accommodate bottles of various sizes, and is enclosed in a housing to control emission of ultraviolet radiation.  An exhaust fan is employed to remove hot air and ozone, which axe produced by the ultraviolet radiation.

Abstract: ABSTRACT OF THE DISCLOSURE:             A roller bearing for endless linear motion wherein a casing mounted on a track rail makes linear motion through a plurality of rollers circulating endlessly.  A circulating path for the rollers is constructed by load track, return hole and direction changing path.  The load track and return hole are straight, parallel to each other and approximately square shape in cross section, respectively. The center of the return hole does not lie in the horizontal bisecting plane of the right angle V groove of the load track.  The return hole is symmetric to the load track with respect to the perpendicular bisector of the segment line joining the centers of the rollers in the return hole and the load track.  The direction changing path is a cylindrical surface or revolution which is approximately square shape in cross section and which is formed by revolving 180° between the load track and the return hole, the axis of revolution being the perpendicular bisector of the segment line joining the centers of rollers in the return hole and the load track.  Thus the most compact roller bearing for endless linear motion having smooth motion and high strength is obtained.
