Abstract: ABSTRACT OF THE DISCLOSURE          Water-soluble .alpha.-ketocarboxylic acids are continuously converted into the corresponding .alpha.-hydroxy carboxylic acids in a diaphragm reactor.  The conversion is carried out in the presence of a substrate-specific dehydrogenase and, as the coenzyme, nicotinamide-adenine-dinucleotide (NAD+/NADH) which has been increased in its molecular weight by linkage to a water-soluble polymer having an average molecular weight between 500 and 50,000.          At the same time NADH is continuously regenerated from NAD+ in the presence of a formate dehydrogenase and formate ions.  The diaphragm must have an average diameter of 1 to 3 nm.  The coenzyme is applied in a concentration of 0.1 to 10 millimoles per litre.  The reactor is continuously fed with a substrate flow containing 50 to 100% of the maximally soluble amount but not more than 2,000 millimoles/litre of the .alpha.-keocarboxylic acid to be reacted, in the form of a water-soluble salt, and 100 to 6,000 millimoles/litre of a formate.  A differential pressure of 0.1 to 15 bars is maintained across the diaphragm.  A filtrate flow containing the .alpha.-hydroxy carboxylic acid formed is continuously drawn off behind the diaphragm.

Abstract: An Apparatus And Method For Thawing Materials Stored In Gondola-Type Containers Abstract An apparatus and method for thawing particular material, such as coal, stored in gondola-type containers, such as rail cars, where-in the container is positioned in a shielded and grounded enclosure, and is engaged by a shielded hood having an open face matching the dimensions of the open face of the container to form a microwave cavity between the hood and the container.  Plural magnetrons are located in the hood, and are energized upon formation of the micro-wave cavity, to emit microwave radiation into the material in the container, whereby the material is heated and thawing thereof takes place.  Prior to formation of the microwave cavity, the top surface of the container open face is thoroughly cleaned, and during energi-zation of the magnetrons, gases released by the particular matter being heated are evacuated from the microwave cavity.  After energi-zation of the magnetron for a selected period of time, the shielding hood is removed from the gondola-type container, and the container is then processed to an adjacent discharge cite exterior to the RF shielded enclosure.  The apparatus and process is virtually entirely automated under the control of a centrally located microprocessor.

Abstract: ABSTRACT OF THE DISCLOSURE             NON-PLUGGING MINIATURE SEAL UNIT     The Non-Plugging Miniature Seal Unit is a device which is attached to the inlet connection of a pressure instrument to isolate its measuring element from the process fluid.  The space between the diaphragm and the pressure element is solidly filled with a suitable liquid.  Displacement of the liquid fill in the pressure element, through movement of the diaphragm, transmits process pressure changes directly to a gauge, transmitter, switch or other pressure instrument.      The Non-Plugging Miniature Seal is different from any other invention of this type, because it has a small diameter sensing diaphragm which can be located flush with the inside wall of a pipe to prevent plugging due to suspended solids in the fluid.  The Seal Unit can be used on low or high pressure applications.  It is self-temperature compensated, very sen-sitive and can easily be installed with standard fittings on large or small pipes as well as on vessels.

Abstract: A PARTIALLY ISOLATED AMPLIFYING GATE THYRISTOR WITH CONTROLLABLE dv/dt COMPENSATION, HIGH di/dt CAPABILITY, AND HIGH SENSITIVITY Abstract of the Disclosure A semiconductor device used for high voltage applications is disclosed.  The disclosed semiconductor device is an amplifying gate thyristor having a gate region, a pilot thyristor, a main thyristor and a compen-sation region.  The compensation region in conjunction with a circuit arrangement and contact regions disposed on the amplifying gate thyristor, supplies a bias voltage developed by dv/dt currents flowing within the compen-sation region that is of equal potential to a voltage developed within the gate region by the dv/dt currents flowing within the gate region.  The circuit arrangement, in conjunction with the contact regions, improves the dv/dt capability of the pilot thyristor without causing subsequent degradation of the dv/dt capability of the main thyristor.  The circuit may be further arranged to provide an improvement to the dv/dt capability of the main thyristor.  Similarly, the contact regions may be further arranged to provide an improvement to the di/dt capability of the pilot thyristor of the device.  The various disclosed embodiments also provide for further improvements to the gate sensitivity of the amplifying gate thyristor.

Abstract: ABSTRACT OF THE DISCLOSURE         There is described an internal combustion engine having a plurality of main suction paths each of which opens at one end into a combustion chamber provided with a piston capable of performing a suction stroke and at the other end with a carburetor.  The ends of the main suction paths opening into the combustion chamber are provided with valves to control the opening and closing thereof.  There is also included a plurality of sub-suction paths each of which communicates at one end with the combustion chamber and at their other ends with the carburetor.  The sub-suction paths open into the combustion chamber to direct incoming suction gases in a generally circumferential direction so as to generate a swirl of suction gas in the combustion chamber during the suction stroke.  This facilitates rapid burn of the fuel-air mixture supplied from the carburetor.
