Abstract: ABSTRACT OF THE DISCLOSURE         L-proline is produced from the methyl or ethyl ester of the L-pyroglutamic acid which is reacted with at least twice the molar amount of phosgene to form the corresponding 1-chloro-carbonyl-5,5-dichloro-proline ester, the corresponding 2-chloro-1-chloro-carbonyl-pyroline-(2)-carboxylic ester is produced therefrom by splitting off hydrogen chloride and the latter ester is catalytically hydrogenated to the corresponding N-chloro-carbonyl-proline ester which is then acidically hydrolized to L-proline.  The L-proline is obtained in large yields.

Abstract: Abstract A brake apparatus is provided for tape recorders, particularly of the coaxial reel type, in which a single brake pad, mounted on a brake arm, engages a pair of adjacent coaxially disposed drive wheels for coaxial tape reels.  The brake arm is biased by a spring into braking engagement with the drive wheels.  A solenoid is operable to withdraw the brake arm, thereby disengaging the brake, when energized. The solenoid is controlled to be energized whenever a drive motor for the tape reels is powered, and to be deenergized when the drive motor is not powered.  The disclosed structure provides automatic braking for the tape reels whenever the drive motor loses power or is shut off, thus providing positive mechanical braking both in a power loss condition and in a parking condition for the tape reels.

Abstract: ABSTRACT                  The alkylangelicins according to the invention are obtained starting from an umbelliferone,  in which the 6-position is already substituted by an alkyl group; in such a way the 7-allyloxy or 7-acyloxy umbelliferone intermediates can form by transposition of the allyl  or acyl group only  the 8-allyl  and 8-acyl  derivatives,  and therefore  the presence,  even in traces, of psoralens is absolutely excluded in the subsequent synthetic steps.                  The    6-alkylangelicins    thus    obtained    are particularly  usable for the photochemotherapy of psoriasys and of other skin diseases characterized by cellular hyperproliferation, as well as for the photochemotherapy of vitiligo and of alopecia aerata.

A television camera comprising a solid-state pick-up device having pick-up elements arranged in rows and columns, wherein a charge transfer can be effected in the columns by means of control electrodes and an associated control circuit. To have the pick-up device generate in a simple way a single or multiple interlace picture signal without specific measures being required due to the structure of the pick-up elements, the control circuit supplies during at least one field scanning period out of a number of field periods forming a picture period, a charge transfer signal for effecting a single charge transfer between all the consecutive pick-up elements in each column of pick-up elements. Possible use: in field transfer devices which must produce an interlaced picture signal. Figure 1.

Abstract: PATENT APPLICATION OF                Alexander Kowalski and Martin Vogel for SEQUENTIAL HETEROPOLYMER DISPERSION AND A PARTICULATE MATERIAL OBTAINABLE THEREFROM, USEFUL  IN COATING COMPOSITIONS AS AN OPACIFYING AGENT                    Abstract of the Disclosure The present invention is concerned with the production and use of water-insoluble particulate heteropolymers made by sequential emulsion polymerization in dispersed particles of which a "core" of a polymeric base is at least partially encased in a "sheath" polymer that is permeable to an acid, such as acetic acid, adapted to cause swelling of the core by neutralization.  The aqueous dispersion of the acid-swollen, base-containing core/sheath particles is useful in making water-base coating compositions, microvoids being formed in cores of the swollen particles in the film during the drying thereof.  Thus, the heteropolymer dispersion can serve as an opacifying agent in coating compositions, such as water-base paints, as a supplement or replacement of part or all of the pigmentary material or extenders that would otherwise be used in such coating compositions.     For convenience of description herein, the terms "core", "sheath", and "core/sheath polymer" are frequently used to refer to the distinct functional components of the individual polymer particles of the essential "mode" of the heteropolymers of the present invention even though in actuality, the components of the polymer particles thereof may not have the precise arrangement implied by this terminology.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method for aligning sheets which are fed via a sheet feeder to a sheet-processing machine.          A side aligning device takes hold of the underside of the sheet which has already been aligned by its front edge.          Then the side aligning device is controlled in such a way that the sheet is moved transversely to the sheet conveying direction into the in-register side position.  The side aligning device holds the sheet in this desired position until sheet-conveying means accept the sheet in-register.          The method according to the invention and the device for implementing this method not only render superfluous a side pulling device with stops, but also permit reliable lateral movement of the sheet into the in-register position.

Abstract: ABSTRACT      A well  cementing  composition  and method  are shown  in which a hydraulic cement, water, and a heat actuated matrix control admix are mixed together to provide a cement slurry composition having improved cementing characteristics over a broad  temperature  range.   The  admix  contains  a  polyvinyl acetate-polyvinyl alcohol polymer which is insoluble in the slurry  composition  at  ambient  temperatures  and  which has greater than about 95% acetate groups converted to hydroxyl groups.   As the circulating temperature rises  in the range from about 90 to 140°F, the polymer begins to solubilize and gradually  thickens  the  slurry  to  combat  thermal  thinning, fluid loss and settling.  A companion cellulosic fluid loss material can be utilized, which is soluble in the slurry at ambient temperatures, to provide initial fluid loss control.
