Abstract: A method and apparatus are provided for data compression in a digital facile document transmission system. In accordance with the method, only alternate scan lines are transmitted, i.e., every other line is deleted in transmission, and at the receiver, the missing scan lines are interpolated from the transmitted data. This compression technique provides a fixed compression ratio of 2 to 1 regardless of the complexity of the input document. The interpolation method relies on comparing, for each picture element to be interpolated, the colors of one or more pairs of adjacent picture elements of the transmitted scan lines and making a decision as to the color of the picture element to be interpolated on this basis.

Abstract: SSICM is a missile configuration which employs spin stabilization, nutatil motion, and impulsive thrusting, and a body mounted passive or semiactive sensor to achieve very small miss distances against a high speed moving target. SSICM does not contain an autopilot, control surfaces, a control actuation system, nor sensor stabilization gimbals. SSICM spins at a rate sufficient to provide frequency separation between body motions and inertial target motion. Its impulsive thrusters provide near instantaneous changes in lateral velocity whereas conventional missiles require a significant time delay to achieve lateral acceleration.

Abstract: Improved means for the chemotherapy of malaria have been achieved with 5-oxy-primaquine analogues having the formula: ##STR1## wherein R.sub.4 represents hydrogen or a methyl grouping, and R represents an alkyl group containing 3 to 12 carbon atoms and pharmaceutically acceptable salts thereof, wherein the salt-forming acid may be organic or inorganic in nature. These primaquine-related compounds afford improvement in the chemotherapy of malaria by exerting plasmodicidal action on malaria parasites which may be present in either the blood, formed tissues, or blood and formed tissues of the mammalian host. Such broad and practical spectrum of effectiveness distinguishes the said primaquine analogues, which may be administered parenterally or perorally to infected animals.

Abstract: The guidance scheme utilizes wide beam width semi-active RF sensors, a prsion roll altitude reference, and a controlled grade pitch, yaw and roll rate gyros to deliver high quality homing guidance information to a spin stabilized controlled missile. A filtering system is utilized to eliminate errors caused by body roll signals generated due to the spin of the missiles. The nutational motion is used to calibrate the sensors. Impulsive maneuvers are utilized to intercept incoming ballistic targets.

Abstract: Disclosed is a method of microwave drying of ammonium perchlorate grinding pheres. A preferred embodiment of the method employs a tunnel oven in combination with a microwave generator having an appropriate power supply. The tunnel oven receives microwave energy through transmission ducts in communication with a channeling device to distribute microwave energy over the grinding spheres to be dried. A preheated air supply facilitates moisture removal from the tunnel oven after the moisture adhered or occluded to the grinding spheres' surfaces is evaporated from the grinding spheres as a result of molecular vibrations of the water molecules after they absorb the microwave energy. A predetermined microwave frequency range and a predetermined drying time are employed to more efficiently remove adhered or occluded moisture from carbide grinding spheres as compared to conventional convection drying.

Abstract: Ethanol is recovered from fermentation products by a countercurrent extraction process which employs diethyl ether as the extraction solvent to form a diethyl ether-ethanol mixture. The ethanol is salted out by adding calcium chloride to the mixture, and the diethyl ether layer is separated and recycled. The calcium chloride in ethanol solution is removed by adding sodium carbonate to form the solids calcium carbonate and sodium chloride which are removed by filtration. The ethanol is recovered as the filtrate.

Abstract: A typical embodiment of the invention provides a means for protecting delte instruments from damage. A flexible membrane separates two chambers in which, during ordinary operation, the fluid pressures are the same. One of the two chambers also serves as a fluid conduit in the system. Pressure loss in the system causes the higher pressure chamber to flex the membrane which closes a port in the fluid conduit chamber, thereby preventing further system pressure loss and consequent equipment damage. The membrane, moreover, can have a small bleed to permit gradual, dampened fluid pressure release.

Abstract: This invention relates to various 2-acetyl- and 2-propionylpyridine thiosemicarbazones which are substituted on the 4-nitrogen atom.

Also disclosed are several synthetic procedures used to prepare the thiosemicarbazones.

Abstract: An apparatus for measuring the strength of a bond between a lamina and its ubstrate, or the like is shown and described. Air, or some other fluid under pressure, causes a gasket to protrude from a piston to seal the atmosphere from a chamber within the piston and the adjacent exposed lamina surface. The fluid also pressurizes this chamber to pull a loading fixture and a portion of the lamina attached thereto away from the substrate. The force required to pull the lamina from the substrate is equal to the strength of the bond.

Abstract: A tomographic marking device is disposed in an electron microscope between a goniometer stage for holding a specimen and a fluorescent screen for displaying a magnified image of the specimen. The device comprises an externally geared, ring wheel, having a pair of spaced-apart, colinearly disposed pins fixed to the inner periphery of the wheel and defining a straight line parallel to both the screen and the tilt axis of rotation of the goniometer stage. Because the magnetic lenses of the microscope rotate the magnified image on the screen, means are provided to rotate the wheel and to indicate the position of angular rotation of the tilt axis of the goniometer stage located on the screen relative to the actual tilt axis of the goniometer stage.

Abstract: An integrated, completely automatic solar heating and cooling system for buildings is disclosed. The system includes a first and a second interconnectable cooling/heating subsystem each of which includes a group of solar heat collecting panels, a heat storage reservoir, and a piping network for transferring the heat exchange media, preferrably water, therebetween. A third subsystem transfers the media from one or both of the reservoirs to a heat exchanger which transfers heat to or from the building's heating and cooling distribution system. Cooling for the building is accomplished by using a fourth subsystem to chill the media in the first subsystem. In the cooling mode, the solar panels of the first sybsystem are covered and used as a heat exchanger, and the second subsystem, isolated from the first heating subsystem, is used to heat the building's hot water system and to provide building heat if required.
