Title: Process and device for conditioning bulk material
Inventor: HEDERER HARTMUT
IPC: F26B3/22
Filed: 1987-11-26
Granted: 1991-10-22
Abstract: Abstract Bulk material such as lignite, hard coal, peat, waste wood, clarifier sludge, waste sludge, contaminated earth, catal-ysts, zeolites and filter cake containing vaporizable ingredients, is conditioned by means of a vibrating plate conveyor divided into a heating zone and a drying zone, using an indirect heat exchange.          The aim of the process is to condition bulk materials composed of particles of different sizes, ensuring a low energy consumption and minimizing the need for the required equipment.  The bulk material is heated in the enclosed heating zone in the presence of the remaining steam pressure and at the final temperature under with-drawal of the vapour from this zone.  In the downstream enclosed drying zone, the content of the vaporizable fractions contained in the bulk material is further reduced by indirect heating under the vapour withdrawal.  The bulk material is separated several times into coarse and fine fractions, the fines being remixed with the coarse fractions which has a higher water content.  The bulk material is mixed several times while being heated in said zones.          The device required for the above process is a vertical vibrating-plate drier (1) which has a plurality of horizontal double-wall plates (2) and an external enclosure.  A particular feature of said device is that some of the plates (6) in the drying section 8 have at least one slotted grid (21) required for separating the fines from the coarse fractions.  Said process and device are suitable for drying hydrous bulk material such as crude lignite, the water content of which is reduced from 58 to 18%.

Title: Method and apparatus employing adaptive filtering for  efficiently communicating image sequences
Inventor: ERICSSON S STAFFAN
IPC: H04N19/70
Filed: 1988-01-07
Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for encoding and transmitting and/or decoding and receiving a sequence of image frames employ selectively a measure of motion displacement for generating a motion compensated image and filter selection data.  The motion compensated image, together with an error signal, provides the receiver with full detail regarding the next frame of a sequence.  In some instances, however, the motion displacement data is inaccurate for portions of the next image frame.  In those instances, the method and apparatus of the transmitter determine whether filtering of a portion of the motion compensated image provides a lower error energy for the resulting prediction of the image.  If a lower error energy can be achieved by low-pass filtering, the data regarding the additional processing of the motion compensated reconstructed image is transmitted to the receiver.  In those instances, at the receiver, the method and apparatus determine from the filter selection data that filtering of a portion of a previously received image provides a lower error energy for the resulting prediction of the image.  If a lower error energy is not achieved by low-pass filtering, the data from the communications path regarding the motion displacement enables the receiver to reconstruct at least a block portion of the image frame.

Title: Irradiation plant
Inventor: BOSSHARD ERNST
IPC: G21K5/02
Filed: 1988-01-21
Granted: 1991-12-17
Abstract: ABSTRACT         The irradiation plant comprises an irradiation chamber (1) with a radiation source (2) and a conveyor system.  The path taken by each conveyor unit is individually preselectable by control elements secured to the unit.  Articles for irradiation are loaded on to conveyor units and brought along tracks (10,11) and shift devices (8, 8a) of two transverse tracks (4, 4A) to end from the irradiation tracks (3).  When a radiation track (3) is loaded or unloaded by the shift devices (8, 8A), there is always a shift device (8, 8A) for each transverse track (4, 4A) at each end of the irradiation track (3). Sensors are present at the branches and transitions between the tracks of the conveyor system and are supplied to a control system which ensures that after each process of loading or unloading an irradiation track (3), not more than one of the two facing shift devices (8, 8A) is loaded.  By means of this irradiation plant, smaller quantities of differently-irradiated articles can be irradiated simultaneously and the plant seldom needs resetting. Operation of the plant is much more economic than for known irradiation plants.         (Fig. 1).

Abstract: FREQUENCY COUNTING APPARATUS AND METHOD       Field of the Invention A device and method for measuring the frequency of an input signal by measuring the number of cycles of the input signal that occur in a sample interval between successive sampling times tn. An integer counter determines an estimated integer number of input signal cycles, and fraction counters determinefractional counts by counting cycles of a clock signal during time intervals between a first measurement time before the sampling time and a second measurement time after the sampling time. A correction circuit refines the fractional counts by determining the phase relationships between the clock and input signals at each measurement time. The correction circuit includes a constant current source, a capacitor, a first switch connected between the constant current source and a reference potential, a second switch connected between the constant current source and the capacitor, and a control circuit forthe switches. The control circuit disconnects the current source from the reference potential at each measurement time, and disconnects the current sourcefrom the capacitor upon the next occurrence of a periodic characteristic of the clock signal that occurs after the measurement time. The voltage on the capacitor then provides the required phase relationship.
