Abstract: ABSTRACT    A method and apparatus to cause a colored backing to be replaced by a background scene, such that the composite scene shows no loss of detail, no edge anomalies, no evid-ence of a colored backing having been present, and no evid-ence that the final scene is a composite, even when the foreground scene contains fine strands of hair, glassware, smoke, fog, or other semi-transparent subjects.  Control signals Eb and Ec are created to cause the foreground and background scenes to mutually interact in a natural manner, so that shadows on the colored backing appear as shadows on the background scene, and the luminance of the background selectively causes back and edge lighting of foreground subjects.  The hue and luminance of the colored backing are continuously and automatically tracked and removed by a subtraction process.  The background level is automatic-ally held constant even though backing illumination changes. Hue and luminance removal and background level are control-led by comparators (35,36) and digital counters (39,40). Levels set by the automatic circuits are retained when the camera pans off of the (blue) backing.  No disturbance occurs to the picture when the camera returns to the back-ing.  Digital memories have manual override (64), allowing the creation of night scenes and other special effects. Chroma and luminance removal are performed by a subtract-ion process on the encoded video signals in both the NTSC and PAL systems.  Chroma removal in the PAL system is acc-omplished by independently tracking (115, 116) the chroma of each line, and is not affected by PAL quadrature errors. The blue cast on foreground subjects caused by lens flare and secondary illumination of the subject by the blue back-ing is removed from the composite image.  Such discolor-ation of the subject may also be removed (121,122) from the subject in the foreground scene when it is not being composited.

Abstract: PROCESS FOR PRODUCING A NONWOVEN FABRIC HAVING THE APPEARANCE OF APERTURED, RIBBED TERRY CLOTH     ABSTRACT     A process for producing a nonwoven fabric having the appearance of apertured, ribbed terry cloth.  The process comprises supporting a layer of fibrous starting material whose individual fibers are in mechanical engage-ment with one another but which are capable of movement under applied liquid forces, on a liquid pervious support member adapted to move in a predetermined direction and on which fiber movement in directions both in and at an angle to the plane of the layer is permitted in response to the applied liquid forces.  The support member has alternating liquid impervious deflecting zones and liquid pervious entangling zones extending transversely to the predetermined direction.  The entangling zones are substan-tially free of raised deflecting means, and the deflecting zones include spaced deflecting means adapted to deflect liquid in a direction transverse to the predetermined direction.  The supported layer is moved in the predeter-mined direction through a fiber rearranging zone within which streams of high pressure, fine essentially columnar jets of liquid are projected directly onto the layer.  The streams of liquid are passed through the layer and the sup-port member in the fiber rearranging zone to effect movement of fibers such that spaced bundles of straight, substantially parallel fiber segments are formed in the deflecting zones, the bundles being oriented generally in the predetermined direction.  Also, spaced, parallel ribs are formed in the entangling zones, the ribs extending in a direction transverse to the predetermined direction, and the ribs comprise entangled fibers that are substantially wholly entangled throughout the ribs.          The spaced bundles interconnect the ribs and are locked into the ribs at the ends of the bundles by fiber entangle-ment.

Abstract: THERMO-MAGNETIC RECORDING OF BINARY DIGITAL INFORMATION                   ABSTRACT OF THE DISCLOSURE         A thermo-magnetic method for recording of a bit of information in each domain of an amorphous alloy thin-film layer supporting small stable domains.  Each domain in the recording layer is first magnetized in a first direction, corresponding to a first binary state, by exposure to a saturation magnetic field.  The remaining binary state is temporarily or permanently recorded in a particular domain by heating (to a lower or high temperature) that doamin volume of the recording layer above a predetermined temperature, but less than the melting temperature of the layer material, and thereafter cooling the heated domain in the presence of a bias magnetic field of direction opposite to, and magnitude less than, the saturation field.  The binary state of each domain is read by interrogation with a beam of energy and utilization of differential effects between the interrogation beam and the direction of the magnetic field in the interrogated domain.

Abstract: ABSTRACT         A method for producing an NPN semiconductor device which has a titanium-tungsten barrier metal only in the N type contact windows is disclosed.  A semiconductor wafer first undergoes the washed emitter process with the result that the N type collector and emitter contact windows are exposed to bare silicon and the P type contact windows are covered by a layer of silicon dioxide.  A layer of titanium-tungsten alloy is deposited on the surface of the wafer.  The titanium-tungsten layer is etched out of the P type contact regions using standard photolithographic techniques.  The underlying layer of silicon dioxide in the P type contact regions is then also etched away.  A layer of aluminum is then deposited across the surface of the wafer.  The conductor interconnect photolithography is used to etch away all undesired aluminum.  The remaining portions of the titanium-tungsten layer, not covered by aluminum signal lines, are then also etched away.  This results in a structure which has titanium-tungsten barrier metal sandwiched between the aluminum signal lines and the silicon in the N type collector and emitter contact windows, but not in the P type contact windows.

Abstract: Abstract of the Disclosure A plasma jet ignitor apparatus for generating plasma from a plasma medium such as hydrogen and for discharging the plasma as a jet into the combustion chamber of an internal combustion chamber.   The apparatus has a plug which has an electrode from which a high energy spark is generated.  The spark causes hydrogen which is introduced into the plasma generation cavity by a fuel line to become plasma.  The plasma generation cavity is defined by magnetic field generation means.  The cavity has an inlet opening adjacent the plasma generation location and an outlet orifice.  The plasma is ejected as a plasma jet from the cavity from the orifice.  The magnetic field generation means is disposed as a magnetic field coil wound about the cavity.  The magnetic field is charged by the discharge of a capacitor at the time of the formation of the plasma in the cavity.  The magnetic field accelerates the plasma out of the cavity through the orifice so that the plasma exits as a high velocity jet and achieves effective penetration.  Timing means are also included for timing the introduction of hydrogen into the cavity  the discharge of the plasma generating spark and the triggering of the magnetic field.

Abstract: TEMPERATURE CONTROL SYSTEM FOR    INTERNAL COMBUSTION ENGINE            ABSTRACT:      When  additional  heat  exchangers,  such  as oil coolers (11) and turbocharged air coolers (12), are mounted in front of or within the normal coolant heat exchanger or radiator  (10)  of an internal combustion engine, a variable speed fan drive (14) may be employed to blow air through all of the heat exchangers to cool the various fluids flowing through those heat exchan-gers.  Since the different fluids usually have different desired operating temperature ranges for optimum engine performance,  controlling the variable speed fan drive (14) only in response to the temperature of the engine coolant can result in overheating of at least one of the other fluids.   This is avoided by temperature sensing (16,31,37) the different fluids and effectively determi-ning which one of them has the highest relative temper-ature in its operating range.   The fan drive is then controlled in response to the sensed temperature of that particular fluid.   In this way, all of the fluids will be maintained within their desired operating temperature ranges.   If the condenser (13) of an air conditioning system is also positioned in front of the engine coolant radiator (10), the compressor discharge pressure in the system may be monitored (66) and if it exceeds a preset maximum allowable level the fan is automatically driven at full speed to maximize the air pulled in through the condenser, and of course through all of the other heat exchangers, to quickly decrease the refri-gerant temperature and thus the discharge pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         The specification discloses a method and apparatus for concentration of vapours present in trace quantities in the atmosphere in a continuous and rapid manner.  It relates especially to a device to enhance the concentration of trace vapours to such a level that they may be more readily analyzed by appropriate instrumentation.  This is of considerable value in connection with the detection of certain vapours which are associated with explosive devices and bombs.  These are of considerable importance now in connection with security at airports and the like.  The specification discloses a method and apparatus for the continuous concentration of trace gases in a gaseous medium, such as air, comprising the steps of bringing the air into intimate contact with a suitable free-flowing adsorption powder in an adsorption region, passing the air containing the treated powder and adsorbed vapours through a cyclone separator to produce a substantially powder-free air stream and a powder containing adsorbed vapours, then passing the powder through a desorption region whereby the powder carrying trace vapours is heated in a heating zone in the presence of a carrier stream at a temperature sufficient to release the adsorbed trace vapours of interest, and thus to produce a vapour-enriched carrier gas stream.  The powder is then normally recycled into the air inlet stream.

Abstract: ABSTRACT OF DISCLOSURE     A secondary containment system which may be manufactured in a factory, shipped and installed in a reasonably low cost and fully usable manner.  In one embodiment, a large membrane of material, completely lines a collection and containment pit along with radiating trenches which drain into the collection pit.  There is a substantial amount of membrane bulk which enables it to bunch in the corners and to provide slack which conforms to irregularities on the earthen walls and floor of the pit.  Thus, localized stresses do not occur at places where the membrane bridges protections formed on the walls, in the corners, or the like.  In another embodiment, the membrane covers a tank in the pit and drapes down to form deep areas where liquids may collect.          A perimeter steel cable surrounds the hole.  The membrane is attached to this cable so that the membrane is mechanically strong enough to meet the shoring requirements of the various occupational safety laws.  Plastic zippers are used to close and to join the various membrane sections.  A cement or sealent may be placed in confronting surface areas of the zipper to preserve the integrity of its seal over the long years that an installation may be expected to remain in the ground.
