Abstract: A screen (14) is mounted in an apparatus for contacting particulate solids with a fluid. The apparatus comprises an elongate column (10) for holding a bed of particulate solids for contact with a fluid, the column being designed to be oriented substantially vertically in use and having a fluid inlet (11) near the bottom for admitting a fluid into the column and a fluid outlet (13) near the top for permitting the fluid to exit the column after passing upwardly through a bed of particulate solids in the column. The purpose of the screen (14) is to screen solids from the fluid exiting the column through the fluid outlet (13). The screen (14) comprises a plurality of vertical screen wires (15), and the screen is located within the column such that all of the fluid passing through the column passes through the screen (14) and thence through the fluid outlet (13). Each pair of adjacent vertical screen wires (15) defines a substantially vertical screen slot (20) therebetween. The opening of each vertical screen slot (20) at the surface of the screen (14) which is upstream in the sense of a fluid flowing through the column (10), passing through the screen (14), and exiting through the outlet (13) during operation of the column (10), has a width suitable for screening solids from the exiting fluid and has a length which is substantially greater than its width.

Abstract: A motor winding system having a main winding and a start winding circuit with a start winding and a PTC resistor in series therewith wherein the resistor is electrically removed from the circuit at a predetermined time after motor starting and remains in this state until motor shut off. The start winding circuit also includes a bimetallic switch in series with the resistor and a series circuit of a capacitor and an electromagnet in parallel with the resistor and switch. At motor start up, current from the main power source is applied across the main winding and the start winding circuit heats up the resistor and causes an increase in the resistance thereof. Also, current through the switch and PTC heat causes the bimetallic element to snap or move when it has reached a predetermined temperature to open the start winding circuit. Meanwhile, low current passes through the capacitor and electromagnet winding, energizing the electromagnet and causing the bimetallic element to be attracted and latched to the electromagnet after predetermined movement. After cool down, the bimetallic element will not return to the closed switch condition, thereby completely removing the resistor from the circuit. The switch remains in the switch open condition until current is removed from the electromagnet at motor shut off with removal of power from the motor windings. The current passing through the capacitor is a small fraction of the current normally present in the resistor during normal motor operating conditions after start up.

Abstract: A drop-on-demand ink jet has an ink chamber (12) coupled to a source of ink (14), and an ink drop orifice (16) with an outlet (18). An acoustic driver (30) produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop orifice and outlet (18). A high voltage electric field is oriented to accelerate ink drops along a path from the outlet to print medium (20). The electric field is time invariant and is the only electric field present along the path during drop formation and accelaration. The size of the ink drops may be varied, such as by driving the acoustic driver with varying drive signals. One preferred form of acoustic drive signal comprises of individual or combinations of plural bipolar drive pulses. The combination of energy imparted by the acoustic driver (30) and the electric field accelerates small and large drops such that the time for the drops to travel to the print medium (20) is substantially the same. The ink jet printer of the present invention may be used to print with a wide variety of inks, including phase change inks.

Abstract: Parameters indicative of gas turbine engine operational characteristics are sensed and the signals processed to derive further operational characteristic information therefrom, each information signal being compared in a subroutine to a corresponding threshold signal for exceedence thereof, the magnitude of each threshold signal being indicative of incipiency of compressor stall, a counter being incremented in the subroutine upon any threshold exceedence occurrence, the amount of counter increment depending on the ability of each information signal to predict the incipiency of stall, the higher the counter value the greater the stall incipiency. The counter is decremented during each subroutine execution, the counter value during the current subroutine execution being compared to that of the previous subroutine execution to determine the direction of stall incipiency. The counter is utilized as a bias signal to an engine acceleration schedule to vary the rate of acceleration as the counter is varied.

Abstract: Apparatus for digital switching of FM signals includes multiple functional switching circuits, each having an input for receiving an FM signal at a first frequency and each generating first switching transients in response to the FM signal. The apparatus includes a dummy switching circuit corresponding to each functional switching circuit. The dummy switching circuits generate second switching transients in response to the FM signal. The second switching transients are shifted in phase relative to the first switching transients such that a crosstalk signal resulting from the first and second switching transients has a frequency of twice the first frequency. The apparatus further includes filters for attenuating the crosstalk signal. By shifting the frequency of the crosstalk signal to twice the frequency of the FM signal, the crosstalk signal is easily filtered.

Abstract: This invention relates to a raster output scanner using, a method of switching video signals from one raster (21) to the next (22) during a scan without the creation of a visible effect. A position encoder is used to determine the position of each raster on the photoreceptor (10), a first distance above a transition point (24) between the two rasters and a second distance below the transition point, in the process direction. Above the first point the video will be supplied by the first raster, and below the second point the video will be supplied by the second raster. From the first point to the transition point the duty cycle will vary from 100 % of data from the first raster to 50% from each raster. From the transition point to the second point the duty cycle will vary from 50% to 100 % supplied by the second raster. In this way, there is a gradual, and invisible, transition from one raster to the next.

Abstract: An indexable cutting insert is disclosed in which, an insert body is formed into a polygonal plate-like shape when viewed from the front, and has a cutting face and a flank face. In the insert body, a cutting edge is formed at an intersection of the cutting face and the flank face. The cutting face is formed into an inclined face downslope toward the inner side of the front face of the insert body. A breaker face is formed on the front face connected with the cutting face. The breaker face projects outwardly in the direction of the thickness of the insert body with respect to the extended plane stemming from the cutting face. On the cutting face, protrusions projecting out from the cutting face are formed, and when viewed from the front, extend towards the inner side from the periphery of the insert body. The protrusion has a ridge portion, which extends perpendicular to the direction of the thickness of the insert body. During cutting operation, cuttings produced by the cutting edge are slightly curled by the ridge portions of the protrusion, the cuttings are guided to the inner side of the front face of the insert body, and as a result, the resistance exerted to the cuttings can be reduced and clogging of the cuttings can be prevented.
