Abstract: An apparatus and method for the recovery of small plastic tissue sections described. A container having parallel sides is rotatably supported on its ends. Slides are placed in the container at an angle. The container is filled with a liquid and the histologic specimens are floated on the liquid within the receptacle. The container is then tilted so that the slides are horizontal and the sections are floating over the slides. A valve allows release of the liquid from the container into a trough. When the water level falls just below the level of the slides the valve is closed and the slides are removed for further processing.

Abstract: A system for locating forward observation posts with respect to a base ston. A continuous electromagnetic wave with frequency f.sub.o is transmitted from an artillery projectile or missile in flight. In addition, a relative time code is transmitted on the same or a separate carrier frequency either from the projectile or from a ground station. The frequency f.sub.o of the electromagnetic wave from the projectile or missile is doppler shifted above or below its basic frequency due to the velocity of the projectile. This doppler signal f.sub.d always goes through its basic frequency f.sub.o or zero doppler at a point which is representative of and identifies an observer's position in the horizontal or subtrack direction of the projectile. This occurs regardless of the observer's distance away from the subtrack. Thus, all observers on a given perpendicular to the subtrack observe f.sub.o or zero doppler at the same time. To locate a specific observer, two projectiles or missiles must be fired.

Abstract: Disclosed is a method of providing an ingition system for substantially sltaneously and uniformily igniting all the internal burning surfaces of a large propellant grain of the internal burning grain type that is employed in an upper stage advanced missile interceptor. The propellant grain to be ignited is also of the type which requires support for reinforcing the grain during high acceleration loads especially before the interceptor stage motor is pressurized. The means for igniting the large propellant grain is comprised of high-velocity deflagration compositions which are derived from cesium dodecahydrodecaborane and which are extruded or formed in a variety of shapes. These shaped high-velocity deflagration compositions are then bonded to a consumable casting mandrel, or to a grain support tube which also serves as a casting mandrel.

Abstract: A thermometric transducer device is provided for use in measuring the temperature of a dielectric, such as human tissue, during exposure of the dielectric to microwave radiation. The system includes a transducer electrode sub-assembly which is partially inserted into the dielectric and comprises a thermistor mounted on one end of an elongate substrate and thick film conductors which extend along the length of the substrate and which are tapered so as to provide electrothermal matching of the heat produced in an equivalent volume of the dielectric so that the transducer electrode serves neither as a heat source or a heat sink. The transducer sub-assembly is connected to measurement instrumentation by a transmission line formed by ultra-thin thin film conductors whose thickness relative to the skin depth of the microwave field in the conductors is such that the conductors are a poor medium for microwave conduction and are thus microwave decoupled.

Abstract: A method and apparatus for adjusting an exposure of a negative image having incremental areas to enhance the contrast of a print resulting from the negative image. The incremental areas of the negative image to be printed are initially scanned providing corresponding sensor signals which are directed to a processing circuit which separates the sensor signals into amplitude ranges according to the amplitude of the sensor signal and according to the amplitude range of the sensor signal as compared to an average sensor signal. Each range is inputted to a signal generator which provides a corresponding signal having an adjusted wavelength determining contrast and an adjusted amplitude determining intensity of exposure, each dependant upon the corresponding amplitude range and amplitude of the sensor signals, respectively. If the sensor signals are at an amplitude which is less than the average sensor signal, the corresponding signal has a proportionally increased intensity.

Abstract: Remote interrogation of biological targets is accomplished in accordance h the present invention by method and apparatus wherein a microwave signal is generated which varies in frequency from a first frequency to a second frequency in a predetermined time period. The signal is divided into two signals, one of which is propagated through a test channel comprising a transmitting antenna for transmitting the signal through the target, and a receiving antenna for receiving the signal transmitted through the target, and the other of which is propagated through a reference channel providing a fixed time delay of propagation. The propagated signals are detected and mixed to produce a time delay spectrum wherein the frequency of each spectral line represents the instantaneous difference in the frequencies of the detected signals.
