Abstract: ABSTRACT OF THE DISCLOSURE                     METHOD AND MEANS FOR SEGMENTALLY REDUCING                      HEAT OUTPUT IN A HEAT-TRACING PIPE   This invention relates to an improvement in a heat-generating pipe made up of a ferromagnetic pipe having an insulated conductor ex-tending through it to a given point so that both the pipe and conductor may be connected in series with a power source of alternating current.           The invention is directed to both a method and means for reducing the heat output over a desired segment of the pipe by reducing the magnetic field created by the alternating current flowing in the insulated con-ductor and that segment of the pipe.  The means may be:  a second electrical conductor internal and parallel to the heat reduced segment; a segment of nonferromagnetic electrically conductive pipe; an electrically nonconductive pipe extending throughout the desired segment shunted by a second conductor; or a portion of the insulated conductor that is exterior to the ferromagnetic pipe along the segment so that  it is magnetically decoupled from the pipe in which a reduced heat output is desired.  The method comprises the requisite steps of connecting an electromagnetic field-decreasing means in the series circuit to reduce the alternating magnetic field produced in the pipe by the alternating current flowing through the conductor inside the pipe.

Abstract: ABSTRACT OF THE DISCLOSURE A composition is disclosed of a solution of a resinous carrier and at least two compounds which thermoparticulate at different temperatures between 60 and 200°C.  A coating is made by applying the com-position to a portion of an electrical apparatus ex-posed to a gas stream.  As the temperature of the coating increases the compounds therein thermoparticulate.  The time between which the compounds thermoparticulate indi-cates the rate of rise of the temperature and analysis of the products of thermoparticulation indicates the location of the coating in the electrical apparatus.  Alternatively, the coating can consist of several layers with a thermo-particulating compound in each layer which thermoparticulates at different temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE In an electrostatographic copier in which imaging material is transferred from an image support surface to an overlying copy sheet in a transfer station, by electrical transfer charges, the variable leakage conduction of these transfer charges by the copy sheet away from the transfer area (to contacting conductive members) changes the available trans-fer field strength, thus affecting transfer efficiency and quality.  Here the conductive members contacting the copy sheet while it is in the transfer station are electrically isolated from ground and connected to feed back the sheet leakage currents to circuitry providing a compensatory change in the applied transfer charges.

Abstract: Abstract of the Disclosure: The present invention relates to monocomponent insulin purified to such a degree that it shows only a single component when analyzed by amide gel electrophoresis using a gel containing 15% poly-acrylamide.  It, furthermore, relates to a method of preparing such insulin from an insulin containing raw extract prepared from pancreas glands, consisting in the working up of the extract in such a manner that the insulin is maintained in dissolved state during the whole processing, without change of phase, until the final recovery of the insulin, the undesired substances being from the beginning of the process until the end removed from the different solvents used.  A preferred method comprises removal of fat from the extract by cooling to a temperature below -25°C and separation of the crystallized fat, concentration of the extract and simultaneous removal of impurities present in the extract, both substances having a larger molecule than insulin and substances having a smaller molecule than insulin, by means of reverse osmosis plant for removal of colouring substances and salts, further purification by means of ion exchange and recovery of the insulin from the concentrated purified solution resulting from the ion exchange treatment by precipitation with metal ions under strong cooling.  The monocomponent insulin may be used in insulin preparations of any kind for clinical use.
