Abstract: Abstract of the Disclosure Apparatus is provided for generating a set of color mixture signals associated with a set of coordinate axes from a pair of quadrature related color mixture signals associated with a different set of coordinate axes supplied from a source.  Means are provided for determining the magnitude of the vector sum of the pair of quadrature related color mixture signals.  Means are also provided from determining the angle between the vector sum and one axis of the set of coordinate axes associated with the quadrature related color mixture signals.  A source of angle values provides the angles between the one axis of the set of coordinate axes associated with the quadrature related color mixture signals and the coordinate axes associated with the color mixture signals to be generated.  Means are then provided for forming the algebraic sums of the angle between the vector sum and the axis of the set of coordinate axes associated with the quadrature related color mixture signals and the angle values from the source.  Means are provided for producing trigonometric ratios associated with the algebraic sums. Finally, means are provided for producing the products of the magnitude of the vector sum times the trigonometric ratios.  The products are the generated color mixture signals.

Abstract: ABSTRACT            In a liquid crystal display based on the bistability effect,  the  distance  between the support plates is smaller that 10 µm and the total twist of the liquid crystal  is between  180° and 360°,  preferably about 270°.   Over the entire viewing area of the display, randomly distributed spacers are provided.   Because of these measures, the range of the bistable action is so narrowed that the display can be driven with operating voltages outside this range, using conven-tional multiplexing  techniques.   A high degree of multiplexing with short switching times and excellent contrast is obtained.   The range of viewing angles is  very large  and independent  of  the direction of illumination.

Abstract: ABSTRACT OF THE DISCLOSURE:            Rivets for use in the aircraft industry are made from a wrought aluminum alloy (Material No. 3.1324 in accordance with DIN).  As that alloy will precipitation-harden at room temperature, the rivets must be closed imme-diately after they have been annealed and quenched.  The time in which the rivets can be deformed can be extended to as much as one week if the rivets are stored below - 17°C.          In order to overcome said disadvantages in the processing of the rivets, 0.002 to 0.3% cadmium is added to the wrought aluminum alloy.  The resulting modified material exhibits a delayed precipitation hardening at room temperature and even when it is fully precipitation-hardened has a very high ductility.  For this reason the precipitation hardening will not impose restrictions as regards the time in which rivets made of said alloy can be closed.

Abstract: ENGINE TEMPERATURE CONTROL SYSTEM            ABSTRACT:      The operating temperature of an internal combustion engine is maintained within desired limits by employing a single coolant temperature sensor (10) for controlling and  coordinating  the operation of  three different temperature control devices  (45,46,47)  for the engine coolant.   When the sensed coolant temperature is in a relatively low range a flow control valve (45) controls the amount of coolant diverted from the engine jacket to a radiator  (48)  to dissipate heat absorbed by the coolant from the engine.   If the coolant temperature exceeds that low range, even though the control valve (45) is fully open and all of the coolant is circulated through the radiator (48), the sensor (10) then effects the opening of radiator shutters (46) to cause ram air to impinge on the radiator (48) to increase the cooling of the coolant.   If the temperature still continues to rise after the shutters (46) are fully open, the coolant sensor  (10)  causes operation of a variable speed fan drive (47) to blow a sufficient amount of air through the radiator (48) to cool the coolant back down to the desired operating range.  Such sequential operation of the three control devices (45,46,47) provides close temperature  control  within  a  relatively narrow range despite wide variations of external conditions and load on  the engine,  resulting  in higher efficiency and longer engine life.

Abstract: ABSTRACT OF THE DISCLOSURE                        The present invention is the method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500°F or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated.  The radiant heat is derived from a flat faced electric quartz infrared heater which has a surface temperature in excess of 1600°F and which maintained for fifteen to forty five seconds at a spacing of approximately one fourth to one half of an inch from the end face of the duct.  The time varies with the size of the pipe being welded; and the heater to pipe spacing may vary widely, from 0.125 inch to as much as 2.0 inches.
