Abstract: A DEVICE FOR STOPPING A LEAK IN A STRAIGHT PORTION OF A HEAT-EXCHANGER TUBE     Abstract of the Disclosure An axial mandrel having good electrical con-ductivity is fitted with conical metal washers and in-sulating pastilles in alternate sequence.  A nut applied against an insulating support at the lower end of the mandrel exerts a compressive stress on the washers, the peripheral edges of which are applied against a lining sleeve placed within a leaky portion of a heat-exchanger tube.  Each washer thus exerts a radial force which applies the sleeve in intimate contact with the tube along a number of circular lines corresponding to the number of washers.  An electric current is passed through the mandrel, the washers, the lining sleeve, thus uniting the tube and the lining sleeve by means of circular resistance welds.

Title: Means for enhancing uniformity in  electron beam spot size in television  picture tubes
Inventor: MIDLAND RICHARD W
IPC: H04N3/26
Filed: 1979-05-25
Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE           This disclosure depicts means for providing greater spot size uniformity across the screen of cathode ray picture tubes. A beam-current-control signal is derived from the horizontal scansion circuit means in which the amplitude of the signal varies monotonically as a function of the distance of the beam spot from the minor axis of the faceplate.  Means for receiving the beam-current-control signal for modulating the luminance signal are provided.  The beam-current-control signal has such characteristics that the modulation causes a predetermined gradational reduction in beam current at least from the minor axis to the minor sides of the faceplate to inhibit beam spot enlargement in faceplate side zones and thus provide greater spot size uniformity across the screen.

Title: Process for recovering bitumen from oil  sand
Inventor: KRUYER JAN
IPC: C10G1/00
Filed: 1979-08-13
Granted: 1982-09-28
Abstract: ABSTRACT OF THE DISCLOSURE   Bituminous sand such as oil sand or tar sand is mixed with steam and water in a tumbler to produce a slurry.  Oversized particles are removed and the slurry is transferred into a water bath containing a submerged moving, apertured, separator, such as an endless belt having an oleophilic surface and top and bottom flights.  The slurry falls through the water onto the top flight of the belt where the bitumen is attracted to the apertured oleophilic surface and adheres thereto.  The adhering bitumen is then removed from the belt.  Mineral particles in the slurry and the remaining bitumen pass through the apertures of the top flight and fall through the water onto the bottom flight of the belt.  The remaining bitumen of the slurry is attracted to the apertured oleophilic surface of the bottom flight and adheres thereto.  The adhering bitumen is then removed from the belt.  The mineral particles of the slurry and a very small amount of remaining bitumen pass through the aper-tures to fall to the bottom of the water bath for subsequent removal.  The process gives a good recovery of bitumen product which has acceptable quan-tities of solid and water contamination.  Compared with the prior art it has the feature that the oleophilic apertured surface does not have to be removed from the water bath to collect bitumen there from.

Title: Welding method for longitudinally seam welding a pipe  blank from the inside using the metal arc welding process
Inventor: KOSHIGA FUSAO
IPC: B23K9/12
Filed: 1979-12-05
Granted: 1981-03-17
Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in longitudinally seam-welding a pipe-blank for welded steel pipe from the inside along a groove or cleft by the metal arc welding process.  That process comprises using direct electric current supplied to a plurality of consumable electrodes in tandem through at least one current supply cable as the welding current.  An even number of consumable electrodes are used.  Half of the even-numbered consumable electrodes are connected in the reverse-polarity manner, i.e., to be posi-tive in polarity, and are used as leading electrodes, and the remaining half are connected in the straight-polarity manner, i.e., to be negative in polarity, and are used as trailing electrodes.  The GMA welding process is applied on the side of the reverse-polarity consumable electrodes which are the leading electrodes.  The submerged-arc welding process is applied on the side of the straight-polarity consumable electrodes which are the trail-ing electrodes.  By this technique magnetization of the pipe-blank and the resulting magnetic arc blow of the welding arc is substantially prevented by causing lines of magnetic force produced by the direct electric currents for welding flowing through the current supply cables introduced into the pipe-blank to cancel each other.  This technique also substantially pre-vents spattering of molten droplets from the straight-polarity consumable electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE           A manifold system for a two stroke cycle vertical shaft internal combustion engine   A series of horizontal bores are perpendicular to the vertical shaft.  A piston located in each bore establishes a combustion chamber and a fuel-air mixture supply chamber therein.  A passage connects the supply chamber to the combustion chamber and a manifold  system connects the supply chamber to a mixing chamber.  Each mixing chamber is connected to an independent fuel supply and to a common air supply.  A valve is located between the mixing chamber and the supply chamber to control the communication of a fuel-air mixture between the mixing chamber and the supply chamber.  When the piston moves toward the combustion chamber a fuel-air mixture therein is compressed and at the top of the stroke ignited to produce combustion.  As the piston moves toward the combustion chamber, the supply chamber expands and draws in a fuel-air mixture.  When combustion occurs, the piston moves toward the supply chamber causing the valve to close and compress the fuel-air mixture now in the supply chamber.  After the piston has travelled a predetermined distance, the combustion chamber is communicated to the surrounding environment and the passages opened to allow the fuel-air mixture therein to flow into the combustion chamber.  At the bottom of the exhaust stroke, the piston again moves toward the combustion chamber to initiate the compression stroke in a cycle of operation.  In order to assure that the fuel-air ratio of the mixture supplied to each supply chamber is substantially identical a dam is located between the mixing chamber and the common air supply.  The dam intercepts and retains any fuel delivered to the mixing chamber hut not communicated into the supply chamber thereby preventing fuel from adjacent mixing chambers being intermingled during a compression stroke  Thus, the fuel-air ratio for each piston remains substantially constant for each piston in this internal combustion engine.

Abstract: APPARATUS AND METHOD FOR CONTAINER RECOGNITION                 Abstract of the Disclosure Apparatus and method for observing containers which are transported through an illumination station, and generating a recognition signal on the basis of leading edge scanning information.  Leading edge scanning information is produced by a trigger photo-detector and a plurality of vertically arranged registration photodetectors.  A container which is to be recognized is carried through the illumination station by a conveyor, and the conveyor generates conveyor clock pulses corresponding to actual move-ment of the container through the illumination station.  The trigger photodetector senses the leading edge of the container, and it generates a trigger signal which enables a counter to begin counting conveyor clock pulses.  The registration photodetectors are positioned downstream from the trigger photodetector and are connected for termina-ting the counting of conveyor clock pulses upon detection of the container leading edge at their respective positions.        There is also disclosure of a vertically progressing arrangement of height detecting photo-detectors positioned above and upstream from the trigger photodetector.  The height detecting photo-detectors perform a height classification at the instant of activation of the trigger photodetector. The system includes a plurality of recognition cir-cuits for recognizing different classes of containers, and the weight classification is used for selecting those recognition circuits to be employed for recognition of the particular container being observed.
