Abstract: ABSTRACT   A thin-profile multi-compartmented inflatable liner for use as an energy-absorbing device inside a protective headgear or other protective equipment. The multiple air compartments with integral intercommunicating air channels are formed of flexible plastic sheets which are dielectrically heat bonded together. The air compartments have within, resilient foam plastic co-acting bafflements with integral protrusions which interact with the intercommunicating air channels to thereby control the rate of air flow between the air compartments in response to an impact compression of the air compartments. The unique construction provides a thin-profile, light weight, high-energy absorbing liner with strength, durability and reliability to a high degree.

Abstract: METHOD FOR OPTIMIZING PROCESS PARAMETERS IN PHOTOACTIVE SEMICONDUCTOR MANUFACTURING IN SITU            ABSTRACT            Materials  and   systems   substantially   having  photoactive properties  are  produced  with  a  high  quality  output  and without  time losses in the fabrication process. To  determine the quality of the photoactive material in situ,  conductivity is  induced  in  the  material  by  exciting  charge  carriers through  irradiation, and an electromagnetic field  influenced thereby is measured, with the result of the measurement  being evaluated  by  a  computer with  a  corresponding  control  of actuating  members  such as valves  and  controllers.  Optimum process parameters are thus found and used for the process.

Abstract: FIBER OPTIC LIGHT TRANSFER DEVICE, MODULAR ASSEMBLY, AND METHOD OF MAKING                      Abstract A fiber optic light transfer device (11) has a plurality of optical fibers (12) with end surfaces (13 and 14).  A locator body (21) for the fibers has a multiplicity of parallel slots (22) through which the fibers extend and by which the fibers are located and mechanically held.  Each slot has first and second sup-porting surfaces (24 and 25) at right angles to one another in mutually perpendicular planes.  First and second reference supporting surfaces (24R and 25R) lo-cate a reference end fiber (12R) perpendicular to a third plane that is mutually perpendicular to the other two planes and a reference ribbon in the second plane. The further end fibers are located in the first plane and at equally spaced intervals in planes parallel to the second reference plane and, when adhered to the sup-porting surfaces, precisely locate and mechanically hold the fibers against movement relative to one another in three mutually perpendicular planes.  In one method a plurality of channel-shaped members, each containing one ribbon, are stacked one on another and cut on a diagonal to form two identical devices.

For the decoding of a data stream which is word-wise protected against errors by a double Reed-Solomon code with symbol-wise interleaving over the code words, first the reliability information for the constituent symbols is aggregated for a code word. The strategy is determined therefrom, entailing the number of erase sym-bols and the maximum number of error symbols to be cor-rected. The correction result is compared with a relia-bility code and on the basis thereof all symbols obtain an at least trivalent secondary reliability indication for decoding in the second code.

Abstract: ABSTRACT     A fusion pad is produced by forming a spiral groove 22 in the pad upper surface  A wire 16 is fed from a reel 18 through a hole in the pad and secured to a terminal on the pad under surface.  The pad is rotated causing the wire 16 progressively to enter the groove 22. The groove side walls have a height greater than the diameter of the wire 16 to ensure that the groove walls project above the wire 16 in the groove 22.  An electrical heating tool 26 is applied to each part of the groove 22 as soon as the wire 16 is located in that groove part to cause the adjacent groove walls 24 to melt at their upper regions.  These molten upper regions collapse inwardly onto the wire 16 therebetween and solidify to retain the wire 16 in the groove 22.

Abstract: ABSTRACT OF THE DISCLOSURE         A destructible container is arranged to maintain the components of a multi-component settable mass in separate regions until they are ready to be mixed for anchoring a fastener member in a borehole.  The container is made up of an elongated outer cartridge and an inner cartridge positioned within the outer cartridge so that a space for one of the components is formed between the inner cartridge and the outer cartridge.  The multi-component mass includes a resin component filled into the outer cartridge and a hardenable component filled into the inner cartridge.  The space within the outer cartridge is divided into two separate  regions, preferably one follow-ing the other in the elongated direction of the outer cartridge.  The resin component is present in each region, however, a thixotropic agent is included in one region but not the other so that the viscosity of the resin component is greatly increased within the one region.  Preferably, the increased viscosity component is present in the region of the outer cartridge forming the trailing end of the container when it is inserted into a borehole so that flow out of the borehole is, for practical purposes, prevented.          Accordingly, a resin component which is highly fluid prior to the mixing operation, such as methylmethacrylate (MMA) can be used.

Abstract: Abstract The present invention relates to a method of wet oxidation of organic waste materials in waste water.  The method is comprised of flowing a stream of waste water including organic waste materials into an insulated well; injecting a flow of oxygen into the flowing stream of waste water; extending the flow of waste water to a depth such that pressure in the insulated well is increased to the pressure required for supercritical water and initially heating with a control unit the waste water at the bottom of the insulated well by flowing an electric current through the water at the bottom of the insulated well to generate resistance heat for the water to initiate hydrocarbon oxidation for sustaining supercritical conditions in the insulated well.  The method further comprises the steps of oxidizing the organic waste materials in the waste water to liberate heat in the insulated well to sustain the temperature required for supercritical water wherein the initial heating step with the control unit is ended after the oxidized wastes sustain exothermic oxidation; and over a period of time, injecting the flow of oxygen into the insulated well with the waste water and also removing water from the insulated well to enable continuous oxidation of waste in the insulated well at supercritical conditions to sustain supercritical temperatures.

In order to avoid that a reverse current flows and enters into the second emitter (E2) when the cell is in the non-selected mode, a diode (D1,D2) is arranged so as to shunt the emitter/base junction of the mono-emitter transistors(T3b,T4b).
