Abstract: Abstract The organ transplants are intended to be used as a replacement (prostheses) for organs or parts of organs, for examples arteries or veins, which have undergone pathological change or are functionally impaired,    The organs, which are taken from a fish, bird or higher mammal, are subjected to crosslinking of the amino groups and of the alcoholic hydroxyl groups of the peptide chains of the intercellular matix by means of a di-, tri- or poly-carboxylic acid     It is advantageous subsequently to treat the crosslinked product with a dialdehyde, in order to bind amino groups which have not reacted, or to free the crosslinked product from material which poten-tially may act as an antigen, by hydrolysis with ficin, papain or a protease having a similar action,     After the hydrolysis, a comprehensive crosslinking is appro-priately ensured using a dialdehyde or a di-, tri- or poly-carboxylic acid,    The resulting prostheses are distinguished by chemical stability, biophysical and biochemical properties similar to those of the natural material and the absence of rejection reactions.

Abstract: ABSTRACT         An apparatus is provided for treatment of organic contaminant containing waste water such that the oxygen demand of the waste water is reduced and methane is produced.  The apparatus comprises an anaerobic digester or filter.  The digester is packed with a media which provides a substantial growth surface area to microorganisms contained within the digester.  The digester also includes recirculation means whereby fluid in the digester below the media is recirculated directly to an upper portion of the digester.  Further-more, the digester has effluent overflow outlets which outlets include a trap to prevent oxygen from entering the digester from the atmosphere.  Fluid to be treated in the digester enters the upper portion thereof passes downwardly through the media, is recirculated by the recirculating means to an upper portion of the digester, and exits the digester after treatment by the micro-organisms therein through the outlet.  Means are provided to withdraw methane produced in the digester therefrom, and to store it, forward it for utilization, or return it to the digester in the lower portion thereof to agitate biomasses of microorganisms within the digester.  The apparatus is further provided with means for adding nutrients for the microorganisms to the digester influent and for adding buffering solution thereto in order to control pH within the digester.

The output of transmitter (26) is connected to one input of a selector (30), the other input of which is connected to a function transmitter (32) in turn connected to the output of controller (16).   The output of selector (30) acts on controller (16).   A disturbance indicator (34) is also connected to the signal transmitter (26), and acts on the selector in such a manner that as soon as the output signal of the signal transmitter (26) falls below a bottom threshold or exceeds a top threshold at the disturbance indicator (34) the controller (16) is influenced by the function transmitter (32) instead of by the signal transmitter (26).

Abstract: A METHOD FOR REGULATING THE POWER SUPPLY TO A DIRECT-CURRENT MOTOR AND A DEVICE      FOR THE APPLICATION OF SAID METHOD     Abstract of the Disclosure The power supply to an electric actuating motor is regulated by reducing the differences between current intensity or voltage and a reference value.  Two trans-ducers measure the current intensity and the voltage.  A selection stage chooses the higher of the two values and a comparison stage delivers a difference signal with respect to the reference value established by a stage of the potentiometer type.  A regulator produces an action which is compared within a comparator with a sawtooth signal emitted by an oscillator.  Depending on the sign of the comparison, a control stage supplies the motor during a variable fraction of the period of the oscillations.

Abstract: Abstract of the Disclosure A process of reducing the oxygen content in gas mixtures to 0.0 - 1.5% by volume is described, in which process the gas is contacted with a solution containing anthrahydroquinone derivatives capable of being oxidized with molecular oxygen under formation of hydrogen peroxide. The supply of oxygen is so adjusted that the amount of oxygen supplied, upon quanti-tative formation of hydrogen peroxide, stoichiometrically corresponds to not more than 90%, preferably 50%, of the sup-plied amount of anthrahydroquinone derivative. The hydrogen peroxide content at the contact surfaces between the solution and the gas must not exceed 100 millimols per liter at a si-multaneous oxygen gas pressure of not more than 100 millibars.   The oxygen-poor gas mixture in accordance with the process of this invention may be used as a protective or inert gas in chemical process industries where use is made of inflammable gases.
