Abstract: A packaging material which comprises a simultaneously coextruded film comprising a conductive ethylene-ethyl acrylate copolymer resin layer containing more than 50 wt.% of ethylene-ethyl acrylate copolymer resin of which content of ethyl acrylate is more than 6 wt.%, 7 to 20 wt.% of carbon black and 0.01 to 1 wt.% of a lubricant, and a polyolefin resin layer. 
     The packaging material of the invention is superior in antistatic property, moistureproofness, light-shielding, tear strength, impact puncture strength, slipping character and heat sealing properties. Its production is easy because of superior moldability, and generations of blocking, fish eye and pin hole are rare. The packaging material of the invention can be made thinner than the conventional packaging material, and expensive metal foil is not necessary. Accordingly, this packaging material is inexpensive.

Abstract: The present invention relates to a process for the manufacture of monopotassium phosphate using solvent extrac. tion technique. According to the invention, the reaction occurs between phosphoric acid and potassium chloride at a temperature between 0 and 100 degrees C. in the presence of an organic solvent comprising long chain primary, secondary or tertiary amine, each chain containing between 6 and 28 carbon atoms. The lower phase containing the monopotassium phosphate is cooled by at least 10 degrees less than the reaction temperature whereby pure crystals of monopotassium phosphate are separated and removed. The upper phase which contains the organic solvent, amine-hydrochloric acid as well as most of the impurities originally present in the starting reagents, is treated with a base at a temperature in the range of 20 to 100 degrees C. whereby the amine is regenerated and recycled to the process. Typical examples of suitable bases are calcium oxide, calcium carbonate or mixtures thereof. The monopotassium phosphate obtained is characterized by its high purity.

Abstract: A pressure switch having mechanical and sol­id state components. The switch includes mechani­cal components that are arranged so the mechanical components provide the electrical connections be­tween a motor and an electric source for the motor. The mechanical components include a fluid pres­sure responsive mechanism which causes contacts of the switch to move with a snap action in response to pressure variations in a fluid system. The solid state components detect variations in the motor cur­rent, voltage and power factor as well as the dura­tion of the intervals during which the motor is ener­gized and interrupts or prevents energizing of the motor when at least one of the variations exceeds a preprogrammed value. The switch includes a cali­bration switch which programs the switch operation for use with the particular motor controlled by the switch and coded diodes that function to indicate the cause of a malfunction detected by the switch.

Abstract: A multilayer semiconductor structure, formed of two or more separate layers of different materials can be selectively intermixed so as to become compositionally modified, such that the distinction between the different original materials is lost, at least partially. This intermixing process employs irradiation with a pulsed or rapidly scanned laser or electron beam, generally at ambient conditions of temperature and pressure, at energy levels which avoid physical damage to the layered structure. The intermixing may be more complete when multiple pulses from the laser or electron beam are employed.

Abstract: In a process and equipment for treating circulation water of open circulation cooling systems, preferably in cooling tower circulation systems, a solution is to be found which simplifies the monitoring and treatment of circulation water of open cooling systems and, in particular, makes this possible over a long period without laboratory analysis and manual monitoring. 
<??>This is achieved in the process according to the invention by arranging that at a preferred location at least a part of the flow is continuously diverted from the circulation water and flows through a compact and standardised modular unit for the treatment of circulation water, in which successively and automatically, the pH of the partial stream of water is determined and, if necessary, depending on the measured pH, acid is metered in to establish a desired pH, the conductivity of the partial stream of water is determined, preferably inductively and, if necessary, depending on the measured conductivity value, a clarifying unit is activated, corrosion protective agent is added, if necessary, to the partial stream of water as a function of the amount of additional water added to the circulation water to make up for losses, at phased intervals organic and/or inorganic biocides are separately added to the partial stream of water through further metering devices and the partial stream of water is filtered in a filter with automatic back washing, and subsequently the partial stream of water is fed back continuously to the circulating water.

Abstract: The picture control signals, in particular colour picture control signals for representing a picture on a representation device, for example of a colour picture tube, must have a specific structure independent of this representation device. The information for the picture to be represented can come from various sources, e.g. viewdata over a telephone line. The conversion of this varying picture information supplied from outside into the picture control signals is normally performed by means of a processor and a further special circuit. The proposed device aims at a rapid conversion accompanied by substantial relieving of the processor, and to enable the user to change such pictures easily. The device according to the invention in each case converts the picture information supplied into code words which are such as to be capable of being converted as rapidly and simply as possible into the picture control signals for the required device in the event of cyclically recurring readout from the refresh memory. In this arrangement these code words are pixel-orientated and thus always relate to the direct pixel information, so that more easily aimed changes of a picture are therefore possible. In addition, an autonomous address calculation ensures a furthest reaching relief of the processor. Conversion, in particular of viewdata and graphics/picture information into control signals for, for example, colour picture tubes. <IMAGE>
