Abstract: MEMBRANE PACK Abstract of the Disclosure A membrane pack is constructed, which includes a highly porous carrier sandwiched between a pair of membrane structures that must be kept continuously wet, the pack having a hole and being sealed around the hole to prevent the passage of polluting liquid lying in the hole, into the porous carrier of the pack.  The membrane pack is constructed by impregnating the carrier with a flowable polymer which can solidify, to leave a thin layer of the polymer on either surface of the carrier, and by then welding the polymer layers to membranes at either face of the carrier. Ultrasonic welding of the membrane structures to the carrier is performed while the membrane structures are wet, the ultrasonic welding dissipating moisture lying at the interface between the carrier and membrace structures to permit even hydrophylic polymers to be utilized.

Title: Process for the determination of the ph value in the  interior of a cell
Inventor: RUHENSTROTH-BAUER GERHARD
IPC: G01N33/84
Filed: 1982-01-26
Granted: 1985-10-08
Abstract: ABSTRACT           The determination of the pH value in the interior of a cell is accomplished through measurement of the fluores-ence emission of a fluorescent substance which is absorbed by the cell through incubation in a solution containing the fluorescent substance.  The fluorescent substance is a substance whose emission spectrum has a pH-dependent frequency at maximum emission, and is employed in the form of a derivative adapted to penetrate the cell membrane and to be split in the cell by enzymes present in the cell such that the fluorescent substance is liberated inside the cell and fluoresces as a function of the pH value therein.  The frequency at which the fluorescence emission maximum occurs is determined through measurement of the fluorescence of the liberated fluorescent substance.  A fluorescent substance particularly suitable for this purpose is 2,3-dicyano-1,4-hydroquinone.  Suitable membrane-penetrating derivatives are 1,4-diacetoxy-2,3-dicyanobenzene, 1,4-dibutyryloxy-2,3-dicyanobenzene and 1,4-di-(tert-butyloxycarbonyl-1-alanyloxy)-2,3-dicyanobenzene.

Abstract: A CONTINUOUS PROCESS FOR THE PRODUCTION        OF ORGANIC ISOCYANATES              ABSTRACT OF THE DISCLOSURE Organic mono- or poly-isocyanates are produced on a continuous basis by phosgenating the corresponding amines.  A solution of the amine to be phosgenated is continuously sprayed through a smooth-jet nozzle into a solution of phosgene continuously flowing through a mixing chamber.  The mixing chamber is maintained at a temperature of 120 to 300°C and a pressure of from 10 to 1000 bars.  The molar ratio of phosgene to primary amino groups is generally from 2:1 to 30:1.

Abstract: Abstract of the Disclosure A large size pneumatic rubber tire for bad or rough roads comprises a number of main grooves in a tread of the tire arranged on both sides of a center circumferen-tial line of the tread and in parallel with one another substantially equally oblique to the center circumferential line and a number of auxiliary grooves in the tread substantially in parallel with one another oblique in a direction opposite to the direction of the main grooves to connect the two main grooves adjacent in a circumferen-tial direction.   The main and auxiliary grooves have comparatively wide  groove widths,  respectively,  and divide the tread into a center zone and two side zones.          These zones respectively consist of circumferentially arranged respectively substantially same shaped center blocks and side blocks defined by the main and auxiliary grooves.  The tire according to the invention can effec-tively eliminate extraordinary temperature rise in the tire without sacrificing the required performances such as wear-resistance, even if under severe operating condi-tions.

Abstract: TILTING SYSTEM FOR ADJUSTABLE HOSPITAL BED            Abstract:   Independently operable adjusting or lifting mechanisms (16,18) are provided at the head and foot ends of the fixed lower base frame (10) of an adjustable hospital bed in order to facilitate independent height adjustment of the head and foot ends of the bed's movable upper frame (12), on which is mounted a mattress supporting structure (14).          Logic circuitry (197-203,207-211,282,248-252, 257,67,258,68,218-222,181,182) controls the actuation of the adjusting mechanisms to position the bed as desired.  When trendelenburg positioning is desired, and is so commanded by the operator, the logic circuitry causes the head and foot adjusting mechanisms to automatically function as necessary to tilt the upper frame directly to a trendelenburg position regardless of its position at the time the command is issued.  Conversely, in response to a reverse trendelenburg command the upper frame is automatically tilted directly from its present position to a reverse trendelenburg position. with such direct and immediate access to trendelen-burg and reverse trendelenburg positions, considerable time can be saved. Moreover, only simple steps are required on the part of the operator.

Abstract: PHOTOLUMINESCENCE METHOD OF TESTING DOUBLE HETEROSTRUCTURE WAFERS            Abstract Under photoluminescence (PL) excitation, the lateral spreading of photo-excited carriers can suppress the photoluminescence signal from double heterostructure (DH) wafers containing a p-n junction.  In any DH with a p-n junction in the active layer, PL is suppressed if the power of the excitation source does not exceed a threshold value.  This effect can be advantageously used for a nondestructive optical determination of the top cladding layer sheet conductance as well as p-n junction misplacement, important parameters for injection lasers and LEDs.

Abstract: METHOD AND APPARATUS FOR IMPROVING THE OPERATION           OF A HEAT GENERATOR                 Abstract of the Invention A method and apparatus for improving the efficiency of a heat generator in which combustible fuels such as fossil fuels, refuse, or other materials are burned is described.  Flue gas generated in the heat generator and combustion air are passed in heat exchange relationship in a heat exchanger.  The heat exchanger is selected so that it removes a substantial amount of heat from the flue gas, whose temperature is consequently lowered to a level where a corrosive pollutant such as SO3 in the form of H2SO4 is likely to condense out.  A pollutant removing liquid is selectively applied onto the portion of the heat exchanger where the flue gas passes through, both to scrub the flue gas and protect that portion of the heat exchanger from cor-rosive effects from condensed pollutants.  Particulates and gaseous pollutants are removed from the flue gas and the heat exchanger by the liquid, which may be a neutralizing liquid such as an alkaline solution to provide a protective sheath for the heat exchanger against the effects of corrosive pollutants.  In the described illustrative em-bodiment, the invention is shown in use with a thermal section for a large scale power plant.
