Abstract: .beta.-Al.sub.2 TiO.sub.5 protective coatings have been developed for both dense and porous ceramics such as SiC and Si.sub.3 N.sub.4 using a chemical solution processing method involving the hydrolysis and condensation of aluminum tri-sec butoxide and titanium butoxide. The solution viscosities, pH values, H.sub.2 O/alkoxide molar ratios, and dip coating withdrawal rates required for crack-free .beta.-Al.sub.2 TiO.sub.5 are 1.0 to 6.2 cP, pH 1-4.5, molar ratio 1.5-10, and withdrawal rate of 2.2-8.0 cm/min, respectively. Conversion of the amorphous coating to crystalline .beta.-Al.sub.2 TiO.sub.5 is achieved by a succession of calcination below 450.degree. C. and a final heat-treatment at 1300.degree. C. for ten hours with controlled heating and cooling rates.

Abstract: A twisted stem helical internal abrading and finishing tool is formed from abrasive containing plastic strips having transverse offset slits along the lateral edges and a longitudinal middle unslit portion. The strips may be stacked with the longitudinal middle unslit portions aligned with the longitudinal axis of a cotter pin, one end of the stack being placed in the bight of the cotter pin. The cotter pin is twisted about its longitudinal axis to form a helical twisted stem from which the slit lateral side or edges extend forming rectangular abrasive fingers uniformly helically arranged. The end of the cotter pin opposite the bight may be inserted into the chuck of a drilling or turning machine to hold and rotate the tool about the axis of the stem.

Abstract: A gooseneck hitch is latched to a trailer platform by a pin which may be shifted linearly to an unlatched position against the bias of a spring so as to permit removal of the gooseneck from the platform. A first detent unit holds the latch pin in its unlatched position once the pin has been moved to that position and as long as the gooseneck remains in an installed position on the platform. As the gooseneck is removed from the platform, a second detent unit releases the first detent unit from the latch pin but continues to hold the latch pin in its unlatched position. Upon re-installation of the gooseneck, the second detent unit is automatically released from the pin and permits the spring to automatically shift the pin to its latched position.

Abstract: The present invention relates to electronic chassis installed on aircraft. More particularly, the present invention relates to a safety locking system for establishing the presence of the mechanical-electrical integrity of a chassis. More specifically, disclosed is a safety locking system for conditionally permitting or disallowing mating of an external connector with a mating chassis connector dependent upon whether or not the chassis is fastened to a support frame.

Abstract: A data path aligner transfers data from an input having N byte lanes with byte enable bits to an output having N byte lanes. The aligner includes first stage having N-1 selector/registers, and a second stage having N selector/registers. Each of the N-1 selector/registers S1(i) in the first stage has inputs including input lanes L(j) for j going from i+1 to N. Each of the selector/registers S2(i) in the second stage has inputs including input lanes L(k) for k going from i to 0, and for selector/registers S2(i) for i less than or equal to N-2, the inputs include the output of a first stage selector/register S1(i). The outputs of the second stage selector/registers supply data selected from the respective inputs to output segment lanes. All of these selector/registers are controlled by a common select signal derived from a data path offset, and all selector/registers are clocked by a common clock.

Abstract: A piano lift and dolly has an upper H-frame that engages a piano and a lower H-frame that is supported on wheels. Four posts extend vertically upwardly from the lower H-frame and are received in downwardly extending tubes connected to the upper H-frame. A jack has its base mounted on a cross beam of the lower H-frame and its jack RAM mounted directly to a center point of the cross beam of the upper H-frame. Two beams of the upper H-frame engage the underside of the piano at different heights with respect to a floor on which the dolly is supported. As the jack is raised, the RAM raises the upper H-frame with respect to the lower one to lift a piano off of the floor. In this way, the piano is moved without the legs of the piano engaging the floor.

Abstract: Efficient transmission and reception of electromagnetic radiation are achieved by an antenna on a substrate. An antenna is fabricated on the top surface of a substrate which includes a periodic dielectric structure. The antenna operates at a frequency within the band gap of the periodic dielectric structure. Radiation emitted by the antenna cannot propagate through the structure and is therefore emitted only into space away from the substrate. When the antenna is receiving, radiation striking the device does not propagate through the substrate but is concentrated at the antenna. A phased array with isolated elements is achieved by fabricating the array elements on top of a substrate having a periodic dielectric structure and by surrounding the circuits associated with each antenna element with the periodic dielectric structure. Radiation from an element or associated circuitry at a frequency within the band gap of the structure cannot propagate into the substrate to interfere with other elements.

Abstract: A system and method of precision automatic scrolling for use in an image display system. Upon selecting a displayed entity having an off-screen end or other point which is desired to be brought into view, the entity's definitional vector coordinate characteristics are compared to the coordinates of the selection point on the display screen. The results of the comparison provide the XY coordinates of the entity which are furthest from the point of selection. The resulting XY coordinates are then made the new center point of the area in view. The current level of magnification is maintained during this operation. The present system and method thus eliminates the need for manual panning/scrolling or demagnification to bring the desired endpoint into view. The present system and method can also be applied to locate and display a nearest endpoint or a closest point of intersection between two entities.

Abstract: In a method of cutting plant tissue for micropropagation, a container (42) containing plantlets (43) Is rotated on a turntable (19). A laser beam (35) is focused on a side wall (36) of the container below the level of a nutrient medium (45). The container (42) is rotated while the laser (35) cuts free an upper portion (36) of the container (12). After cutting, plant material is cut in a subsequent step by the same laser. Preferably the container is inverted during cutting of container and plantlets.

Abstract: A radiometer is described which coherently detects the thickness of oil films on water by converting continuous-frequency microwave or millimeter-wave brightness temperature versus frequency measurements from the frequency/wavenumber domain to the oil-film-thickness domain (received power versus film thickness) using Fourier-transform signal processing.

Abstract: A memory part (10), with memory (14) subarrays arranged in different ways, provides one data input and output path for normal operation and another data input and output path for test mode operation. The part furnishes one data output multiplexer (40) connected between the memory (14) subarrays and the data output buffers (24) for normal operation. The part furnishes another data output multiplexer (52) connected between the memory (14) subarrays and the data output buffers for test mode operation. Test mode circuits (30) on the memory part select operation of the one and the other multiplexer. Data input gating circuits connect between the data in buffers (22) and the memory (14) subarrays and connect all or one of the data input leads D0-8 to the memory subarrays in response to operation of the test mode circuits.
