Abstract: Abstract of the disclosure:     Microbial polysaccharides can be quantitatively precipitated from their aqueous solutions, in particular directly from the fermentation solutions, in an acidic medium in the form of an adduct with a tertiary amine which has a long-chain alkyl radical.  It is advantageous to add the amine to the polysaccharide solution and then to carry out the precipitation, in particular by adding the dispersion obtained to an acidic coagulation bath.          The adducts are suitable for use as thickeners and for preparing the free polysaccharides.

Abstract: ABSTRACT This invention relates to improvements in palladium-carbon catalysts for the production of hydrogen peroxide from a mixture of hydrogen and oxygen in the presence of an aqueous liquid capable of inhibiting the decomposi-tion of hydrogen peroxide. The improvement comprises pretreating the catalyst with an aldehyde or ketone, and, preferably, also pretreating the catalyst with a dilute solution of hydrochloric acid. Improved catalysts are obtained by reducing a soluble palladium compound deposited on a high surface area non-graphitic carbon base, in the form of a dried powder, with hydrogen at 27-200°C.

Abstract: ABSTRACT          A method and apparatus for the transmission, recording, and playback of color television signals is provided. A luminance signal (Y) and a relative thereto narrow band chrominance signal (R-Y, B-Y) in each case are time-compressed and are transmitted successively during the line scanning period. The luminance signal togther with the horizontal synchonizing pulse and the front and back porch are time-compressed before the transmission. The signals are time expanded for reproduction such that they become time  congruent for  the  picture  reproduction.  The simultaneous compression of luminance signal and line synchronizing pulses renders the method independent of the respective television standard, since the transmitted signal is changed back to the original signal.

Abstract: P-1327.     Title of the Invention Optical Character Reader Abstract of the Disclosure An optical character reader which radiate the light onto a form in which characters or symbols are entered, receives the reflected light from the form by an image sensor, images the characters or symbols on the surface of the image sensor, outputs from the image sensor electric signals corresponding to the characters or symbols image-formed, and optically read the characters or symbols on the basis of the electric signals, so that in a case where the image sensor moves away from the form and the reflected light is scarcely received, a current flowing in a lamp (a light source lamp) for radiating the light is reduced, and also, when the image sensor is positioned completely on the form and the value of electric signal becomes smaller than the preset value, the current flowing in the lamp is increased until the quantity of the reflected light is of optimum value, thereby prolonging a life span of a lamp and largely improving a correct read percentage for radiating the characters or symbols to be read in an optimum quantity of light.

Abstract: ABSTRACT OF THE DISCLOSURE         A drive pinion disengaging device for use in rack and pinion hoists includes an outer section of rack having toothed portions above and below, an at least potentially toothless portion, and a bridging rack section adapted to be removed at said toothless portion by said drive pinion when under a predetermined load to permit the latter to disengage the rack in case of malfunction.  This permits the large rotational inertia to be dissipated without injury to the drive mechanism.  The point of disengagement is such as to occur preferably only when the hoist is engaged by the safety landing buffers (since the drive pinion is normally the only effective support for the hoist).      The bridging section rack may be in the form of a sliding rack maintained in a longitudinal slot in the main rack (extending across the toothless portion and slightly up into the toothed portion above) and normally secured in place across an actually toothless portion by a shear pin, detent, and the like; or may be a rack having shearable teeth (preferrably thinner than the main rack, or optionally of a softer material).

Abstract: CULTURE FLASK            ABSTRACT OF THE DISCLOSURE        A culture flask comprises a top wall, a bottom wall and a continuous side wall joining the top wall and the bottom wall.  A neck originates at an inter-secting portion of the top wall and the side wall and projects outwardly therefrom at an angle directed away from the bottom wall.  The neck has an opening therethrough to provide access to the interior of the flask and is adapted to cooperate with a separate sealing member.   A relief wall extending between a portion of  the bottom wall and the side wall defines a recess in the flask. This recess is large enough to allow stacking of individual flasks whereby the recess of the upper flask in such a stack pro-vides clearance for the neck on the next lower flask in the stack so that the bottom wall of the upper flask freely contacts the top wall of the lower flask.

Abstract: ABSTRACT       A novel enzyme of bilirubin oxidase and a conventional enzyme of laccase oxidize bilirubin to biliverdin without formation of hydrogen peroxide. Conjugated bilirubin in biological fluid may be caused to react with the bilirubin oxidase of a microorganism of genus Myrothecium origin, while total bilirubin in biological fluid may be caused to react with the bilirubin oxidase or laccase under the presence of specific additive compound.  In the conventional enzymatic methods of quantitative determination of glu-cose, cholesterol, neutral fats, free fatty acids, phospholipids or uric acid all existing in biological fluid, the interference of such determination by bilirubin coexisting in said fluid may be prevented by adding bilirubin oxidase or laccase together with said specific additive compound to the reaction system.

Abstract: STABILIZED ACTIVE HALOGEN-CONTAINING            DETERGENT COMPOSITIONS AND METHODS          Abstract of the Disclosure A detergent composition containing a stabilized active halogen source is disclosed.  An active halogen source, such as a hypochlorite, in aqueous solution, is stabilized by combining it with known anhydrous or partially anhydrous builders, as well as fillers, defoamers, polyelectrolytes, and hydroxides to form a solid detergent composition.          Preferably, the aqueous solution of the active halogen source is first combined with at least one sulfonamide.  It is found that inclusion of the sulfonamide further improves stability, particularly at higher temperatures and permits the active halogen source to be stabilized as a slurry.  The destaining activity of the halogen remains effective even after a prolonged storage period.
