Abstract: In a pulsed coherent Doppler radar, a Q-switched laser source (12) develops a laser beam to have a high intensity pulse portion (16) and a substantially lower intensity trailing tail portion (18). An acoustic-optic modulator (20) upon which the laser beam is incident directs substantially all of the energy of the pulse portion along a first propagation path (22) towards a target, such as atmospheric aerosols, and substantially all of the energy of the tail portion along the second propagation path (24). The target reflects the pulse portion as a received signal (26). A heterodyne detector (28) upon which each of the received signal and the tail portion is incident, determines the Doppler shift of the received signal with respect to the tail portion. The detector uses the tail portion as the local oscillator. The acousto-optic modulator (20) also upshifts the frequency of the tail protion (18).

Abstract: A family of logic circuits using nonhysteretic superconducting quantum interference devices (SQUIDs) connected together to perform various functions using a common operating principle. Each circuit has an output line, first and second power supply lines having first and second voltage states, and input lines that can have one of the two voltage states. A pull-up circuit, having at least one SQUID, is connected between the output line and the first power supply line, and the input lines are coupled to the pull-up circuit in such a manner as to pull the output line to the first voltage state only if the input lines conform with a selected combination of voltage states. A pull-down circuit, also having at least one SQUID, is connected between the output line and the second power supply line, to pull the output line to the second voltage state only when input lines do not conform with the selected combination of voltage states. A single configuration of SQUIDs can be connected to perform any of six different basic Boolean logic functions on signals applied to the input lines. Additional SQUIDs allow the performance of more complex logic functions. A slightly different arrangement of SQUIDs operates as a two-port random access memory cell.

Abstract: A cache memory control apparatus for controlling a virtual address cache memory includes a main storage provided with a table in which task codes of (m+n) bits are sequentially set with respect to tasks of 2 m+n  (m is 0 or a natural number and n is a natural number) selected from a plurality of tasks which can be executed by a processor. An index of a virtual address outputted from the processor is applied to a cache memory as a lower address thereof. An ID number of a task intended to be executed by the processor is set in a first register, and a task code (or a lower n-bits thereof) set in the table correspondingly to the ID number is applied to the cache memory from a second register as an upper address. Therefore, the cache memory is divided in accordance with the task code (or the lower n-bits thereof). In addition, in order to specify data for a task of the ID number in a divided area, an upper m-bits of the task code is stored in a tag memory together with a tag of the virtual address, and the tag of the virtual address outputted by the processor and the upper m-bits of the second register are compared with a tag read from the tag memory.

Abstract: A process for the valorisation of waste materials is described, in which unsorted refuse is subjected to at least one high-temperature treatment. In this case, the waste material is first compressed batchwise to compact packs, while including any liquid fractions present and retaining its mixing and compound structure. While maintaining the action of pressure, it is then introduced in constant shape into a channel heated to over 100 DEG C and held therein, being pushed in frictional contact with the walls of the channel, until the initially present liquids have evaporated and mechanical restoring forces of individual waste components have subsided. An at least partial thermal degassing takes place. The lumpy solid conglomerate pushed out of the channel in this state of stable form or structure is introduced into a high-temperature reactor held at a temperature of at least 1000 DEG C and forms therein a gas-permeable bed. In a process variant, the liquid residue materials are, if necessary after separating off at least a part of the metallic components, transferred into a second high-temperature melt, using the energy of the gases obtained in the degassing of the waste materials. Entirely inert, high-grade industrial products in a semi-finished and/or finished form are obtained from this melt with a substantial part of their inherent energy.

Abstract: In a well known way an orthogonally sampled television picture of standard definition can be converted into a pattern with the double density of picture elements by separately interpolating new picture elements both horizontally and vertically, whereby diagonal lines do not remain intact. According to the invention the process is such that first the orthogonally sampled picture is converted into a quincunx sampling pattern by interpolating new picture elements between the original lines. Then the quincunx pattern is converted into an orthogonal pattern by interpolating between these picture elements other new picture elements. The method is particularly applicable to display a television of standard definition in a high definition television.

Abstract: Read column conductors (44) and write column conductors (34) of a memory array (12) are addressed by respective triggerable sequential pulse generators (40,30) which, upon receiving respective trigger pulses (RP,WP), provide respective read and write address pulses to respective column conductors of the array. Data to be stored is written in parallel to cells of the memory a column at a time at a rate determined by the write sequential pulse generator (30) and is recovered a column at a time at a rate determined by the read sequential pulse generator (40). Advantageously, (1) the ratio of the read and write rates may be selected (28) to provide time compression, time expansion or constant delay of video data; (2) additionally data may be written and read concurrently without bus contention and (3) addressing is simplified by a timed application of trigger pulses to the pulse generators whereby there is no need for application to the memory of binary addressing data.

Abstract: A high-sensitivity superconductive digitizer (10) which utilizes a dc superconducting quantum interference device (SQUID) (38) to convert an input current or magnetic flux into a frequency signal which is converted by a counter (60) into a digital representation of the input. This measurement requires that the SQUID (38) be operated in a linear region of its periodically varying output. To insure locking the system into a fixed point in the periodic signal, a digital flux-locked loop is employed which utilizes a digital integrator (70) and digital to analog converter (72) in a feedback loop. A waveform generator (46) produces a dithering modulation waveform in the SQUID (38) and an up-down counter (60) finds difference signals between alternating waveforms. This difference signal is then fed to a digital integrator (70) and converted to analog by a digital to analog converter (72) and fed back to the SQUID in a feed-back loop to lock the SQUID (38) to a fixed operating point.) The analog to digital converter (10) of the present invention offers very high sensitivity with low power dissipation and very high speed.
