Patent EP-0546210-A1 (EP)
Inventor: CRAFTON SCOTT P
IPC: B22D29/04
Filed: 1991-12-11
Abstract: 5 n7 An improved method and apparatus for heat treating metal castings with sand cores provides for removal of the sand core and recovery of the sand core material for reuse. The method and apparatus eliminate the need for removing the sand core from the casting prior to heat treatment and thus eliminate the labor, expense, and possible damage to the casting incidental to conventional core removal techniques such as chiseling and shaking. The method involves heating the casting with sand core therein to a temperature sufficient to burn off the binder component of the sand core. The sand comprising the sand core is then blown out of the casting by directing a flow of air over the workpiece. The sand thus dislodged is then collected for reuse. According to the disclosed apparatus, the castings are heated in a furnace (11) having fans (44) for directing a flow of air over the workpieces. The sand dislodged from the castings falls into a trough (50) in the lower portion of the furnace, where it is collected and conveyed to a central collection (60) bin for reuse. In another aspect of the disclosed apparatus, the castings are subsequently immersed in a quench tank. The quench tank includes agitation means for agitating water over the castings to dislodge remaining sand. The sand falls to the bottom of the tank, where the sand and a portion of the water are removed from the tank. A major portion of the water is then removed from the sand so that the sand can be reused.

Abstract: An electron-beam test probe system (400) in which a pulsed laser-beam source (404) and a photocathode assembly (430) are used with an electron-beam column (426) to produce a pulsed electron beam at a stabilized repetition frequency. A pulse picker (414) allows the pulse repetition frequency of the pulsed electron beam to be reduced to a submultiple of the pulsed laser repetition frequency. A test pattern generator (416) is programmable to apply a desired pattern of test vector patterns to an electronic circuit to be probed, the test vector patterns being synchronized with the stabilized laser-beam pulse repetition frequency. A timebase circuit (412) allows the test vector patterns to be time-shifted relative to the pulsed electron beam. The electronic circuit under test can thus be probed at any desired point in the applied test vector pattern by control of the pulse picker and by time-shifting the test vector pattern.

Abstract: An apparatus for winding into a roll a knitted fabric (W) produced in a circular knitting machine and for conveying the roll to the outside of the knitting machine. A knitted fabric (W) hangs below the knitting machine and is wound around a pair of horizontally aligned takeup shafts (20) that are shiftable away from each other and toward each other until they are thrust against each other. At the start of the winding operation, the takeup shafts (20) are shifted toward each other, and when the shafts approach positions to leave a gap between inner gripping ends (27, 29) of these shafts (20), a knitted fabric insertion link mechanism (30, 31, 34) provided alongside the takeup shafts is extended toward the gap, and a fabric thrust arm (39) on a distal end of the link mechanism pushes and insert a portion (Wa) of the lower starting end of the hanging fabric into the gap. Thereafter the gap is closed so that the lower starting end of the fabric is firmly gripped between the gripping ends (27, 29) to enable start of the winding operation.

Inventor: WHITE BRADLEY E

Abstract: A biosensing system is described which determines whether a measured current is varying in accordance with a predetermined Cottrell current relationship. The system includes a test cell with at least a pair of electrodes which extend into a reaction zone, which reaction zone includes analyte reactants. An analog signal detector, in combination with a microprocessor, take plurality of current measurements between the electrodes over a plurality of succeeding measurement times, after a sample is placed in contact with the analyte reactants in the reaction zone. The microprocessor also stores a plurality of succeeding cpmparison constants which are derived by taking the inverse ratio of the square root of a measurement time divided by the square root of a subsequent measurement time. The microprocessor selects a pair of succeeding measurement times; derives a ratio of the currents measured at those times; and then compares the ratio of those currents with the comparison constant previously derived for the pair of succeeding measurement times. If the comparison indicates that the measured current ratio is dissimilar from the comparison constant, an indication is developed that the current between the electrodes is not varying in accordance with the Cottrell relationship. The plurality of current measurements are also used to calculate total charge transferred, Q. Q can then be used as a second means of calculating the final result.
