Abstract: \            Abstract The process according to the invention is related to the production of high alpha-cellulose pulps suitable for chemical processing and special papers by means of a multi-stage cook.            Steamed chips are prehydrolyzed by using a strong acid, e.g. sulfuric acid, whereby 20 to 30 % of the dry matter of the wood is dissolved under suitable process conditions. The pre-hydrolysis liquor is removed from the cooker by means of a counter-current wash, whereafter the chips are conveyed to the actual sulfate cook.        The hydrolysate is separated with a high dry matter content and efficiently. In addition to this, the process is charac-terized in that the furfural content of the prehydrolysis liquor is very low, which makes the further processing of the prehydrolysis liquor easier.

Abstract: Abstract The present invention provides a process for upgrading a hydrocarbon material in the presence of a molten salt in a manner which reduces the requirements for expensive ceramic materials to withstand the corrosive nature of the salt.  A molten salt containing carbon is introduced into a heat generation zone which is located in a lower portion of an upwardly extending elongated reactor.  Oxygen is introduced into the heat generation zone in an amount sufficient to react with substantially all of the carbon and to heat the molten salt to a desired temperature.  The heated molten carbon-oxygen reaction flows upwardly through the reactor to a hydrocarbon material reaction zone which is located within the reactor and above the heat generation zone.  The hydrocarbon material to be treated is introduced into the reaction zone and into the molten salt where it produces gaseous reaction products and unreacted carbon entrained in the flowing molten salt.  Thereafter the molten salt is introduced into a quench zone which is located above the reaction zone and into which there is introduced a quenching medium to reduce the temperature of the molten salt to a temperature below that at which expensive materials of construction, such as ceramics, are required.

Abstract: Abstract Recovery of germainium from the effluent of optical fiber manufacturing processes depends on the realization that the germanium is to a substantial extent in gaseous form.  Thus, to separate the germanium effectively appropriate measures are taken to separate not only particulate matter but also gaseous germanium compounds.  This separation is done through among other steps an appropriate solvation and precipitation to remove the gaseous germanium material.

Abstract: NON CONTACT ISOLATED CURRENT DETECTOR                      ABSTRACT          A receiver for sensing track currents includes a toroid coupled to the track rails via a single conductor.  The toroid has an air gap in which a linear Hall sensor is inserted.  The voltage of the Hall sensor is applied to signal processing circuitry including a low pass filter, amplifier and level detectors.  In one embodiment of the invention comprising a track occupancy detector, second and third windings coupled to the toroid are selectively energized from a potential source to provide MMF's in the toroid  of one and another polarity, and of a level less than the MMF provided by an occupied track section.  The amplifier includes first and second channels for amplifying signals of opposite polarities.  Each channel of the amplifier is coupled to a pair of level detectors, one of the level detectors in each pair is a vital level detector with the threshold set at about 50% of the threshold of the other level detector in the pair.  A lack of occupancy is indicated when, during normal operation, level detectors trip in pairs. Lack of failures is checked by opening the conductor to the track rails and sequentially energizing the second and third conductors, and noting that one level detector in each pair trips in response to energization of the second or third conductors, respectively.  Another embodiment of the invention is used as an approach detector by comparing current level in the rails with a fixed threshold, as current increases above the threshold an approach indication is given.

Abstract: ABSTRACT OF THE DISCLOSURE  Multiple copies of a foreign DNA I coding for the production of a protein may be introduced into eucaryotic cells by cotransforming suitable cells with foreign DNA I and with foreign DNA II which includes a functionally deficient, amplifiable gene coding for a selectable or identifiable trait, preferably carried on the same DNA molecule as a foreign DNA III, which includes a functional, amplifiable gene coding for another selectable or identifiable trait.  The cotransformation is carried out under suitable conditions permitting selection or identification of cells expressing the gene on DNA I or that on DNA III, but not that on DNA II.  The cotrans-formed cells so identified or selected are recovered and cloned under conditions where the functionally deficient gene on DNA II is expressed.  Cells expressing the gene on DNA II are recovered.  They  contain multiple copies of DNA I.  This method can be used to produce mRNA tran-scripts or protein products such as human and animal growth hormone, insulin and the like.

Abstract: AUTOMATIC LIGHT CONTROL SYSTEM            Abstract of the Disclosure A system is disclosed for automatically con-trolling the light intensity of a light source as a function of the amount of light received by a photo-sensor.  In a preferred embodiment the light source illuminates a reference background which, in turn, reflects the light incident thereon to a photosensor in a video camera.  In response to this reflected light, the photosensor produces a video signal which is pro-portional to the amount of light reflected thereon.  A first means is responsive to the reception of the video signal over a preselected period of time for providing a first signal which is proportional to the amount of reflected light received by the photosensor over that preselected period of time.  A second means is respon-sive to the first signal for generating a control signal to automatically cause an adjustable power supply to change the voltage applied to the light source as a function of the amplitude of the control signal.
