Abstract: In a process and an apparatus for the biological purification of water with the aid of a closed trickling filter which is operated with pure oxygen and/or air, and with a downstream upwards filter with floating matter and intermittent flushing, the saturation of the gas blanket which mainly contains oxygen in the pressure trickling filter is controlled by choosing the operating pressure so that the oxygen supply on the one hand corresponds to the biochemical oxygen demand of the water, and the on the other hand a residual oxygen content dissolved in the water makes continuation of a biological final purification in the upwards filter possible, and thus replaces conventional final clarification. <IMAGE>

Title: Flat cathode ray display tubes
Inventor: CAPLE ADRIAN
IPC: H01J29/02
Filed: 1986-09-09
Abstract: A flat cathode ray display tube has an envelope (12) divided into front and rear portions by a partition (20) carrying frame deflection electrodes (42) with an electron gun (30) and line scanning deflector (34) positioned in the rear portion, the electron beam (32) being directed initially parallel to a flat faceplate (14) of the envelope, turned through 180° by a reversing lens (36) into the front portion and then deflected by electrodes (42) towards a screen (16) on the faceplate. In addition to the electrodes (42), the components (30), (34) and (36) are all also mounted on the partition forming a sub-assembly whereby correct mutual positioning is ensured and assembly facilited. A spacing structure (55, 58) accurately spaces the sub-assembly from the faceplate and supports also an electron multiplier (44) for beam current amplification. Respective elements of the partition and spacing structure engage each other and envelope side walls for location purposes.

Abstract: An architecture security fuse circuit is disclosed for secur ing the architecture of a configurable programmable logic device. The storage element of the circuit is a floating gate transistor cell 124. Data stored in the cell is determined by the amount of charge trapped within the oxide-isolated polysilicon floating gate region. The security fuse is initialized (erased) during device fabrication to allow access to device architectural data. Such initialization is accomplished by a technique that the device user cannot duplicate, via an extra probe pad P21 accessible only during wafer probe. To deter the effects of floating gate charge loss which may occur during subsequent fabrication steps, the fuse circuit is adapted to provide a reduced memory cell read voltage, thus providing greater margin against thermally defeating the security fuse. A regenrative feature is provided to strengthen the erased cell during every device «clear» cycle. Once the security fuse is programmed, the data defining the device architecture may not be interrogated or altered, and the memory cell 124 is unchanged by the regenerative feature.

Abstract: A plurality of side rails, cross rails, side and corner legs are prefabricated from a square, tubular, 12 gauge steel material. Separable side and corner connecting members formed of substantially the same tubular steel material include projecting arms and bridging members that are inserted into the open ends of the side rails, cross rails, side and corner members to assemble the table. The connections are secured by bolting the structural frame members to the connecting members. Tubular rectangular side tracks are secured to the upper surface of the side rails in certain installations to provide support for wheeled carriages that are adapted to move longitudinally of the table. The side connectors and corner connectors are, in general, fabricated identically, then utilized in the assembly by slightly different orientation, hole patterns, and the use of the different bridging members.

Abstract: A technique for recognizing hand-drawn graphic symbols operates on vectorized graphic data, including lines, arcs, and circles, that have been produced by an automatic drawing recognition system. The user creates segmented rule bases for recognizing various symbols by describing the geometric structures of recognizable symbols and subsymbols. The rule bases each are compiled into a respective decision tree. Fetched input vectors and entities are placed in software "blackboards", and more particularly, into appropriate symbol slots and subsymbol slots thereof. The growing symbol and subsymbols on the blackboards are continually restructured until they form closed loops or the blackboards are filled. The decision tree then is applied to all possible permutations of the symbols and/or subsymbols to accomplish partial or complete recognition. An inference engine subsystem controls application of the decision trees to limited bits of the symbols and subsymbols, matching decision subtree segment labels to attributes associated with the blackboard data, and orders the matched data according to degree of matching to effectuate application of the decision tree to the linked lists.

By using such error frames, a decoded word is generated for each frame, the probabi­lity that a decoded word actually is the transmitted word is calcu­lated and the decoded word, whose probability value satisfies prede­termined criteria, is emitted as decoded message. A device for carrying out the method is also provided.
