Abstract: ABSTRACT             A decimating filter utilizing first and second switched input capacitors for sampling an input signal on opposite phases of a first sampling clock signal.  The switched input capacitors are connected to an integrating circuit for filtering the sampling signal.  An output of the integrating circuit is sampled according to a second sampling clock signal having a frequency equal to a submultiple of the first sampling clock signal frequency.  By sampling the input signal on opposite phases, the input signal is effectively sampled at twice the first sampling clock signal frequency.  Accordingly, in applications involving high sampling frequencies, such as digital signal transmission, the input signal can be sampled at a sufficiently high frequency without requiring a prohibitively high input sampling clock frequency.        The decimating filter is of simple design and can be inexpensively implemented on an integrated circuit chip requiring small area.

Abstract: ABSTRACT     A technique is disclosed for correcting cyclic code data stored in a memory.  The data to be corrected is stored in a first area of the memory as a data packet.          The data packet has a data field and an error correction field which are comprised of a predetermined number of bits.  A timing generating means successively generates first and second timing signals with a predetermined time delay.  At the first timing signal, the data to be cor-rected is read out of the first area of the memory and transmitted along a first line of a switching means.          With respect to this data, error syndrome calculation is performed by an error syndrome calculating means.  Based on the result of this calculation, the error detecting means detects whether an error is included in data to be corrected, and outputs correction data.  Using this cor-rection data, the correction means corrects the data to be corrected, which is read, once again, out of the first area of the memory and is transmitted along a second line of the switching means at the second timing signal which is generated in synchronism with the end of error detec-tion.  The corrected data is written in a second area of the memory in accordance with a third timing signal.

Abstract: ABSTRACT OF DISCLOSURE      A pressurized cyclonic combustion method and a cylindrical burner apparatus for pressurized combustion of particulate solid fuels to produce a pressurized clean effluent gas.  In the burner, the particulate solids such as wood chip are fed tangentially into a primary combustion chamber at its inlet end and flow at high tangential velocity in a helical  path through the burner.  Oxygen-containing combustion gas such as air is supplied tangen-tially at high velocity through multiple ports spaced along the burner length to maintain and/or increase the high tangential velocity and produce high centrifugal forces on the particulate solids and provide for prolonged combustion and produce  high burner volumetric heat release rates exceeding about 400,000 Btu/hr ft3.  A choke opening is provided centrally located at the combustion chamber outlet end for promoting prolonged combustion of solid fuel particles upstream of a quench zone.  A secondary combustion chamber is provided downstream of the choke opening.  Also, a quench gas stream is introduced into the choke zone preferably in a tangential flow direction opposite to the helical flow in the burner primary combustion chamber, so as to effectively mix the quench gas with the hot effluent gas and reduce its temperature, usually to about 1400-2000° F as determined by downstream metallurgy consid-erations.  The resulting pressurized effluent gas can be further processed to remove any existing fine solids, and the clean pressurized gas can then be expanded in a gas turbine to produce useful power.

Abstract: ABSTRACT:          "Phase-control loop".     In digital systems clock signals are generated from an external clock reference signal for the purpose of synchronization with the aid of a phase-control loop 1 incorporating a frequency-controllable oscillator 2. In practice synchronization problems occur due to the phase inaccuracy of these clock signals relative to the clock reference.          By a two-level control of the oscillator fre-quency in a plurality of cycles, located within a period of the clock reference signal, using a pulse-width modulator 12, the phase accuracy of a clock signal to be derived from the oscillator output signal is improved.          In a preferred embodiment the loop 1 comprises: storage means 16, control means 17 and selection means 18 for providing in accordance with a given phase control strategy a phase-accurate oscillator output signal, this accuracy already being obtained on a small time scale.
