Abstract: A cellular automaton part is provided with cellular automata each including a plurality of cells.  Each cell is provided with a growth period state deriving circuit for growing a cell column and a stable period state deriving circuit for stabilizing the cell column.  An input/output part carries out input/output in/from the cellular automata in relation to a target problem, and outputs the same also to an evaluation part.  The evaluation part operates the degrees of application of the cellular automata with respect to the target problem, so that an evaluation reflecting part decides next initial states of the cellular automata and operations of the growth period and stable period state deriving circuits on the basis of evaluation values of the evaluation part.

Abstract: The present invention relates to a process for manufacturing frame members for picture frames and to the product of that process. The process comprises the steps of forming a plastics extrusion and cutting it into lengths and applying to the lengths of plastic extrusion a solvent based wood paste which is then moulded or otherwise shaped such that it forms ornamentation on the surface of the plastics extrusion and it is then allowed to dry. This process makes use of the low cost of extrusion plastics moulding but enables the ornamental features that would otherwise only be obtainable by injection moulding to be obtained with the extrusion moulding.

Title: Pulse based cable attenuation measurement system
Inventor: BOTTMAN JEFFREY S
IPC: G01R31/02
Filed: 1995-11-29
Granted: 1999-05-25
Abstract: A pulse-based cable attenuation measurement system provides a measurement of attenuation characteristics of a cable over a wide frequency spectrum. A main test and troubleshooting unit of a cable test instrument applies stimulussignals via a selected one twisted pair in a LAN cable to a pulse receiver in a remote unit that in turn causes a pulse generator to produce a specified pulse of known amplitude and duration that is applied as a measurement pulse to a separate but adjacent twisted pair within the same bundle or cable. A measurement system analyzes the measurement pulse after it reaches the main unit and provides attenuation versus frequency information to determine whether the amount of signal loss due to attenuation in the cable is acceptable or not.

Abstract: The present invention concerns a method of separating variable ores containing copper,  lead, zinc and the like as the refining material for non-ferrous metals and gangue minerals such as pyrite, quartz, feld spar and the like from dug out ores and, particularly, it relates to a  flotation method.     For obtaining non-ferrous metal valuable ores as concentrates from ores by a flotation method, flotation is conducted by using gaseous sulfurous acid or aqueous sulfurous acid as a depressant for controlling the floatability of pyrite.  The flotation method comprises measuring the redox potential of an ore solution before and after the addition of gaseous sulfurous acid or aqueous sulfurous acid and determining an optimum addition amount by utilizing a proportional relationship present between the difference of the potential and the valuable quality enhancing rate.     According to the method, it is possible to judge the effect of depressing pyrite, that is, the effect of sulfurous acid for enhancing the valuable quality without complicate analysis or test and, further, when the method is applied to automatic control, an utmost economical merit can be obtained by quality control of concentrates or saving of wasteful consumption of the reagent.

Abstract: A method is described of encoding pixel colour values for a digital video image frame in which each different colour within the image is assigned a colour value. A predominant colour is identified for the image frame and, in a first embodiment, each pixel having a colour other than the predominant colour is separately coded as its respective colour value (0010 to 1111), with runs of three or more successive pixels of the predominant colour being run-length encoded. A further code (0000 0011 cccc), similar in arrangement to that indicating a run, is provided to allow a change in the specified predominant colour during the course of a frame. In a further embodiment, runs of all colours are run-length encoded but with a shorter coding scheme for runs of the predominant colour or, in a still further embodiment, a small range of predominant colours. A principle use for these coding schemes is to improve efficiency of coding for certain classes of image material.
