Abstract: An improved method of casting an article decreases the time required to cast the article without affecting the quality of the article. When a directionally solidified (DS) casting is made, molten metal is poured into a mold cavity. One end of the mold cavity is exposed to a chill plate which initiates solidification of the molten metal. As the metal solidifies, a dendritic structure grows upwardly into the mold cavity. Molten metal is disposed in the interstices of the uppermost portions of dendritic structure. As the metal in the mold cavity cools, the molten metal in the interstices solidifies and the dendritic structure, including a region containing some molten metal in the interstices, continues to grow upwardly toward the upper end of the mold cavity. The directional solidification of the metal in the mold cavity is promoted by slowly withdrawing the mold from a furnace as the molten metal solidifies.

The apparatus and process are especially designed for detecting leaks in small components, such as the hermetic seals of electronic components.

Abstract: Television camera apparatus for generating auxiliary signals such as a VITC signal, an alphanumeric character generating signal, and a window signal for use in gating video related signals to camera adjustment circuitry. The apparatus includes a memory for storing data words representative of auxiliary signals to be generated, a microprocessor for accessing the data words from the memory, and a parallel-in/serial-out (PISO) shift register for receiving the accessed data words in parallel and for shifting them out bit serial so as to thereby generate the auxiliary signal. A first-in/first-out (FIFO) register interfaces the PISO shift register to the microprocessor and memory. The microprocessor uses an internal "refresh" register, normally used to refresh dynamic memories, to access data words for loading into the FIFO. The same circuitry is used for generating plural auxiliary signals.

After each marking, the feed roller feeds the tape corresponding to the remaining length and the tape is cut. The sequence can be preset in a program.

Abstract: Trip devices are disclosed for attachment to existing utility meters to detect revolutions of a dial arm of the meter. Two embodiments are disclosed, each including a spring-biased shaft extending through a base and a shoe on the end of the shaft. As the dial arm rotates, it catches and deflects the shoe, thus rotating the shaft. The shoe then slips off of the dial arm and returns to its original position under the urging of the spring. In one embodiment, shaft rotation is detected using a magnet and reed switch arrangement. In the other a mercury switch is instead used.

Abstract: A microscope having a first mirror located below its stage, such mirror being rotatable and bodily shiftable to selected positions to reflect light at various angles with respect to the optical axis so as to provide for various degrees of dark-field illumination of a specimen on the stage. Said mirror is also shiftable to a position to reflect light coincident with the optical axis to provide for bright-field illumination. This mirror has a mounting which is slidable within a horizontal slot in a side wall of the base of the microscope, the mounting permitting rotation of the mirror at any position along the slot. A second mirror, which may be used to spotlight the specimen being examined, is carried by a mounting block on which the lens body is supported, the block being vertically movable for the purpose of focusing the lens system. The second mirror is pivotal about a horizontally-disposed axis and adapted to reflect rays from a light source onto a specimen on the stage.

Abstract: A glassware package formed from a foldable blank has a top wall, a bottom wall, a pair of end walls, and an open front and back. The top and bottom walls include means for retaining a plurality of glassware items therein. Each end wall includes a flat end wall panel and a pair of support panels extending inwardly therefrom. The support panels are joined to each other at a location spaced inwardly from the end wall panel and are supported off the end wall panel. The end wall panel and support panels together form a beam-type end wall which abuts the top and bottom walls and resists relative movement of the top wall toward the bottom wall. When the blank is printed on one surface only and folded so that the printed surface forms the outer surfaces of the package, the visible sides of the support panels, and thus the insides of the end walls, are formed from the printed surface of the blank, thereby allowing the insides of the end walls to have printed matter thereon.

Abstract: A burner for use in a heat regeneration system for a combustion furnace. The burner includes a burner shell having two internal chambers, wherein the first chamber is disposed on the flame axis of the burner, and the second chamber surrounds the radial perimeter of the first chamber. A gas permeable, annular regenerative bed separates the first and second chambers such that gas flow between the first and second chambers must travel through the regenerative bed in a direction which is generally radial with respect to the flame axis. The burner has "flue" and "fire" modes of operation. Valving elements are included for supplying combustion air to the second chamber under pressure when the burner is in the fire mode, and for exhausting products of combustion (POC) from the second chamber when the burner is in the flue mode. In the disclosed embodiment, the burner valving elements are annular and integral with the burner body.

Abstract: A rotary actuator is operable under the influence of fluid pressure to rotate a driven member. The rotary actuator includes a drive member which extends into a chamber in a housing. Helical splines interconnect a piston and the drive member to rotate the drive member upon axial movement of the piston in the chamber. The piston is held against rotary movement relative to the housing in one embodiment by a pair of rollers that engage tracks disposed on opposite sides of the piston and in another embodiment by a corresponding oval-shaped configuration of a portion of the piston and an internal portion of the chamber in the housing. In one embodiment of the invention, a rack gear on the piston rotates a pinion to actuate a valve and restrict fluid flow to the chamber when the piston is approaching an end-of-stroke position. A one-way clutch may be connected with the drive member so that the driven member is only rotated in one direction rather than being oscillated upon back and forth movement of the piston.
