Abstract: Abstract Process for the preparation of N-.alpha.-alkoxyalkyl-carbox-amides, and some representatives of this class of compounds and secondary products obtained therefrom N-.alpha.-Alkoxyalkyl-carboxamides are prepared by reacting primary or secondary amides of aliphatic, araliphatic or aromatic carboxylic acids, or cyclic carboxamides (lactams) which are not capable of forming an aromatic system, with open-chain .alpha.-halogenoalkyl ethers with at least 3 C atoms per molecule, in the presence of tertiary amines.    N,N-Bis-.alpha.-alkoxyalkyl-carboxamides can also be obtained from the primary carboxamides.    The reaction products, of which the compounds V and VI:                              (V)               (VI), wherein R4 = C1-C4-alkyl and R5 = CH3 or C2H5, are new, are intermediates mainly for the preparation of N-alkenyl- or N-vinyl-carboxamides, of which, in turn, the compounds VII are new:                                       (VII), The N-alkenyl- or N-vinyl-carboxamides can them-selves be processed to give valuable homopolymers and copolymers.

Title: Method and apparatus for drying tobacco

Granted: 1984-05-01
Abstract: 1934-356a ABSTRACT OF THE DISCLOSURE             A continuous stream of tobacco particles is conveyed through a conditioning zone wherein the stream is agitated and is directly contacted by a current of hot air. The moisture content of the thus dried tobacco particles is measured downstream of the conditioning zone and the temperature of hot air is changed when the measured moisture content of dried tobacco particles deviates from a desired value.  A second parameter of hot air (e.g., its initial moisture content) is varied when the temperature of freshly dried tobacco particles deviates from a preselected temperature.  This ensures that the moisture content of tobacco particles does not fluctuate subsequent to cooling which follows the drying operation.

Abstract: ABSTRACT OF THE DISCLOSURE         The efficacy of a high pressure sodium arc discharge lamp is increased by reducing the wall loading and/or current density of the arc tube.  Adequate arc tube wall temperature of at least about 1100°C is maintained by the use of radiant or thermal insulation or infrared reflection films or by the use of an arc tube material having a low thermal radiant emittance.  The lamp is constructed from a non-vitreous arc tube having electrodes sealed into its ends.  A metal framework provides support for the arc tube and an electrical path to the upper electrode.

Abstract: FIXED-CONTACT STABILIZER                 ABSTRACT OF THE INVENTION    A drill string stabilizer in which the wall-contacting wear elements or blades are secured in their accommodating pockets by a lateral interference fit.  One embodiment includes recess-and-projection connections between end-to-end aligned, individual wear elements, the surfaces of mating parts permitting rotation.  Cap screws and locking blocks are also employed in some embodiments.  Surfaces of the locking block and the pocket permit its insertion without longitudinal movement.  An alternate embodiment not using a plurality of elements or a locking block employs a transverse thrust surface which is slightly angled to permit rotation fitting into the accommodating pocket.  The blades are made to assure uniform side pressure within their respective accommo-dating pockets by slight inward dimension tapering or by longitudinal underneath blade slotting to provide a leg structure that flexes, the tapering or slotting acting in opposition to natural loosening that would occur if a uniformly dimensioned and non-flexible blade were pressed into a uniformly dimensioned pocket.

Abstract: ABSTRACT OF THE DISCLOSURE           For a multi-strand continuous casting installa-tion there is proposed accomplishing the transverse conveying or transfer of the cut strand sections, not as was heretofore conventional practice by means of a single clearing or removal movement occurring over the entire width of the installation, rather by means of a number of successive partial conveying strokes or movements, wherein the strand section is displaced from its starting position either through the distance (s) or the distance (s'). Consequently, there is required for each strand section a number of shorter partial conveying strokes or displace-ment movements corresponding to the ordinal number of the strand from which it is derived, and thus, during cutting of shorter strand sections the clearing time can be better accommodated to the cycling of the cutting operation.  The displacement paths, depending upon the technique employed, amount to either s = d. (N - 1) / N or s' = d. N / (N + 1), wherein N constitutes the number of strands and d their spacing. The apparatus for performing the method contains transport carriages possessing pivotable pawls which perform the displacement paths driven by a lever mechanism.

The cavity within the cylinder is divided into two working chambers by a piston unit. The piston unit is connected to a piston rod extending through the piston rod guiding and sealing unit. The cavity within the cylinder is filled with a damping liquid. The compensation chamber defined radially between the cylinder and the container is partially filled with damping liquid and partially filled with gas. adjacent the piston rod guiding and sealing unit, there is provided a by-pass connecting the working chamber adjacent the piston rod guiding and sealing unit and the compensation chamber.          This by-pass defines a  throttling flow cross-sectional area. This flow cross-sectional area is defined by a temperature sensitive member having a high coefficient of thermal expansion, such that the throttling flow cross-sectional area is reduced in response to increasing temperature. By this reduction the reduction of viscosity is compensated for, such as to maintain the damping characteristic of the shock absorber unit approximately invariable within a predetermined range of operational temperatures.

The wedge assembly, when the operating structure is displaced away from the jaw ends of the levers, is operative to spread the other pair of ends of the levers apart, the operating structure being effective to apply a high wedging force-to-pull force ratio during initial movement of said operating structure away from the jaw ends of said levers and to progressively diminish the aforementioned ratio as the operating structure is displaced further away from the jaw ends of the levers.
