Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides a magnetic flux sensing instrument for locating bodies generating a magnetic flux and/or distorting the earth's magnetic field.  The instrument comprises first and second Hall effect devices, each of which generates an electrical signal proportional to any such anomalous flux to which each device is exposed with the devices themselves being spaced apart from one another, such that when approaching a body, the first Hall effect device is positioned for a different exposure to the anomalous flux and generates an electrical signal different from the second Hall effect device.  The instrument further includes first and second field bucking members for offsetting effects of the earth's magnetic field on the two Hall effect devices and controlled by a processor receiving the electrical signals from the Hall effect devices to induce first and second bucking fields for opposing the anomalous flux at the first and second Hall effect devices, respectively.  The processor, in turn, provides first and second flux related signals, representative of the level of bucking required at each of the first and second Hall effect devices and a means for comparing the magnitudes of the first and second flux related signals with an output for showing differences therebetween indicating presence of the body.

Abstract: ABSTRACT OF THE DISCLOSURE          In the production of mechanical pulp, a refiner (defibrator) is driven by a steam turbine. The steam supply for the turbine comprises process steam generated in the refiner during the refining action, which steam is preferably passed through a reboiler.  Some make-up energy is necessary to provide all of the power for driving the refiner, the make-up energy being preferably provided by clean steam from an accessory source introduced to the turbine by a steam ejector.  A portion of the process steam, and the steam discharge from the turbine, can be used for presteaming the chips (comminuted cellulosic fibrous material) before introduction into the refiner.  Any condensate from the turbine may be fed to the reboiler.  Reduction gears are provided between the turbine and the refiner drive shaft so that the refiner is driven at optimum rpm for the particular material being treated.  A wide variety of other structures, such as a mechanical steam compressor, and hydraulic units, can be utilized to obtain optimum desired characteristics.  To increase efficiency, the system can be used in association with a boiler for the co-production of electricity and steam.  Process steam from the defibrator, after passing through the reboiler, is super heated by a heat exchanger associated with the boiler.  The boiler provides energy for driving a turbine connected to an electric generator, as well as providing additional steam input to the steam turbine for driving the refiner.

Abstract: Abstract of the Disclosure A controlled descent apparatus for lowering a person from an elevated place includes a cable which is wound on a drum and is unwound from the drum by the weight of the person to effect the descent.  To limit the rate of descent, the drum turns as the cable is unwound and drives a positive displacement pump the output of which is through a flow control valve.  The latter is set to permit a preselected maximum rate of flow so that the drum turns at a correlated maximum speed and thus limits the rate at which the cable is paid out during the descent.  In the unlikely event that the valve fails to limit the speed of the drum, a centrifugally operated brake is automatically energized at a somewhat higher speed of the drum whereby the descent continues at a faster but still a safe rate.  The cable is guided through an opening, such as a window, in an outside wall by an arm which is formed by inner and outer sections pivotally connected to each other with the inner arm pivotally connected relative to the wall so that the arm may be placed in a compact stored condition.  To use the apparatus, the outer arm section first is swung down and latched to the inner arm section in a ready position and then the arm is swung to an active position in which the outer section projects through the window.  The apparatus also includes alternative power and manual means to rewind the cable on the drum for the next descent.

Abstract: A B S T R A C T          A process for reading-out information from electrically polarizable data carriers by means of electron beams The information recorded in the data carrier in the form of a locally variable electric polarization is scanned and selected by means of an electron beam.  For this purpose, the secondary electrons produced on the surface of the data carrier are used.   The data carrier is simultaneously either periodically heated by radiating electromagnetic waves or charged with ultrasonics.   Potential fluctuations of equal frequency thereby arise on the surface of the data carrier dependent on the local polarization, which fluctuations result in a modulation of the secondary electrons.   The secondary electron flow thus receives information via the polarization conditions stored in the data carrier.   To recover this information, the secondary electron flow is frequency-selectively amplified and electronically evaluated according to amount and/or phase. A polyvinylidene fluoride film (PVDF) is preferably used as data carrier.

Abstract: ABSTRACT OF THE DISCLOSURE    One or a series of different size tote boxes may be extended in  height  by  securely fastening a ring on top of it  or  them, which  ring  is  preferably  snapped to the top  of  the box  by opposing hook-shaped tabs or interlocking elements.   The ring is of a height to effectively change the height of the box, and if a series of different height boxes are involved,  the height of the ring   is such as to change a lower height box into a higher  box of a size  not  to be found  in  the  series. By  effectively constructing  the top of the ring in a manner similar to the  top of the box,  with respect to interlocking,  rings may be  stacked one  upon another to increase the height of the  boxes.  Interior partitioning,  particularly  for  circuit boards,  is  such  that spacing between boards may be readily changed in a secure manner. slotted circuit board holders have edges for insertion in opposed vertical slots,  which edges are offset with respect to the plane of  symmetry  of such holders so that the holder may be  removed, rotated 180° about a vertical axis and reinserted to provide  for a  change in spacing less than the spacing between slots in which the board holder is inserted.

Abstract: ABSTRACT: Computer tomography apparatus including a combined recur-sive and convolution filter.         In a computer tomography apparatus in accordance with the invention the advantages of the convolution cal-culation are combined with the advantages of recursive filtering. The processing unit for the measurement data in-cludes a convolution filter which has only 64 convolution factors and which performs the central part of a convolution calculation (the number of measurement data amounts to, for example 512 or 1024) and a parallel-operating recursive filter which approximates the rests of the convolution cal-culation situated outside the central part by recursive fil-tering of the measurement data. Using five different multi-plication factors and a corresponding number of attenuation factors, ample accuracy is achieved. By variation of only the 64 convolution factors, a large number of different filters can be realized, without it being necessary to change the factors for recursive filtering.
