Abstract: An improved First-In, First-Out data buffer and method of operation incorporates a plurality of arrays of random-access memory cells in column and row orientation per array in which all the cells in a row of one array are precharged simultaneously as memory cells are accessed for read or write operations in another array. Also, all the cells in a row of the other array may be precharged as the memory cells in the one array are accessed independently for read or write operations. Accesses to memory cells in addressed rows alternate from one array to another so that the signal conditioning of the memory cells in one array can take place before access in needed and while memory cells are being accessed in another array. Improved status logic unambigously designates the conditions of empty, half full and full, independent of the sequence of data read and write operations. Data signal driver circuitry controls the rate of change of data output signals for improved noise performance and compatibility with external circuitry.

Abstract: Ceramic articles having improved fracture tough­ness properties are prepared by a powder metallurgical process wherein ceramic particles having an average parti­cle size of between about 0.5 and about 60 micrometers in diameter, are injected with a beam of accelerated metallic ions to produce a supply of metallic ion-containing ceramic particles. The metallic ion-containing ceramic particles are cold compacted into a form by applying pressure there­about. The form is then heated at a temperature of at least about 800°c in an atmosphere comprising a gas such as oxygen, nitrogen, and mixtures thereof, whereby the gas reacts with such injected metal ions to produce a metal-gas reaction product which is dispersed throughout the form.

Abstract: In a bending magnet comprising a core (1) which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles (3a, 3b) are formed and a vacuum chamber (4) for storage of a charged particle beam (5) is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils (2a, 2a′; 2b, 2b′) for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion (7a) of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion (7b) of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam. With this construction, the magnetic flux density becomes uniform in the gap between magnetic poles where the magnetic flux passing through the inner and outer circum­ference side portions is concentrated and the magnetic flux distribution is uniformed in the orbital direction in the gap, thereby eliminating adverse influence upon the charged particle beam, and the bending magnet can be very effective for use in a synchrotron or a storage ring.

Abstract: A rotary processor (10) has enclosed processing passages defined by channels (40) in the rotor (12) and a stationary coaxial closure (16). At least one processing passage (41) is used as a stabilizing passage and another (43) as a metering passage, whose volume and cross section are less than the stabilizing passage. A feed of plastic or polymeric material enters the stabilizing passage (41) and may be subject to fluctuations or disturbances arising in external upstream equipment or within upstream stages of the processor itself. Substantially all material in the stabilizing passage (41) is diverted through a first transfer passage to an entrance into the metering passage (43). An adjustable metering (throttling) element allows a controlled first flow of material to be carried downstream through an adjustable gap between this metering element and the bottom of the metering passage. This controlled first flow is discharged for providing material having uniform flow or at least a marked reduction in such fluctuations and distrubances. The excess material which does not pass through the adjusted gap forms a recycled second flow which is returned back through a second transfer passage into said stabilizing passage for recycling. A modified embodiment shown as metering pumping apparatus includes pairs of stabilizing and metering passages sharing in handling throughput with adjustable throttling means for each metering passage. Interconnecting transfer passages equalize operation among these pairs. A transfer passage is also shown extending from an upstream processing passage to and past a metering passage to a stabilizing passage.

Abstract: The present invention provides an expandable ECL matrix shifter which has very few interconnecting wires. The shifter can perform a multicolumn right shift or a multicolumn left shift in one cycle, and it has independent wrap and fill capabilities. Two 2 to 1 multiplexers are provided for each bit position of the input signals. The input signals provide one of the inputs for both of the multiplexers. The second input of each multiplexer is a signal indicating what type of fill is desired. The shifter has horizontal data input lines, vertical data output lines, and diagonal select lines. A bipolar transistor is located at each intersection of a data input line and a data output line. These transistors selectively connect the data input lines to the data output lines in response to signals on the diagonal select lines. Each horizontal data input line is divided into two parts. The division of the data input lines into parts is along a major diagonal of the matrix. The parts of the data input lines on one side of the major diagonal are activated by the output of one of the multiplexers, and the parts of the data input lines on the other side of the major diagonal are activated by the outputs of the second multiplexer.

Abstract: It is proposed for a process for separating liquid parts and fine granular parts from a sugar suspension to obtain the control variables for controlling the centrifuge from measurement of the surface density of the filtercake which is produced in the centrifuge during the centrifugation process. A radiometric measurement can be used for this in particular. It is possible to derive from the time course of the surface density plots based on such a measurement of surface density the relation with the physical composition of the filtercake at the time of measurement, from which in turn the control variables can be derived, for example for the addition of water and the length of the washing phase. 
<??>The control of a process of this type is therefore possible completely automatically and with optimal quality in a straightforward manner with a single continuous measurement.
