Abstract: Process for the preparation of polyester resins Abstract The invention relates to a process for the preparation of polyester and alkyd resins from bifunctional and/or polyfunctional carboxylic acids and/or derivatives there-of and from bifunctional and/or polyfunctional alcohols.          The reaction is carried out in stirred kettle reactors which are operated discontinuously and equipped with rec-tifying columns.  During the entire reaction an entrain-ing agent is introduced into the reaction mixture below surface level, with thorough distribution, by means of a delivery device in order to improve the transport of the products of the condensation reaction.  In addition, the condensation reaction is carried out under an absolute pressure of 1.5 to 10 bar at least until the maximum re-action rate has been reached.  The pressure is then re-duced to atmospheric pressure at a gradient of -0.05 bar/ hour to -5 bar/hour in a second reaction phase.  The re-action is continued under normal pressure until the pro-duct exhibits the desired properties.  The reaction temper-ature is between 180 and 320°C.     The process times, in particular are shortened as a re-sult of this process, and the process products, which are exposed to heat for a correspondingly shorter time, are distinguished by improved properties.

Abstract: ABSTRACT         The invention provides a method and an apparatus for discharging a substance contained in a cartridge or the like from said cartridge. The substance is prevented from flowing out by a sealing member provided at the outlet of the car-tridge. To open the cartridge, a relative displacement between the cartridge and a coupling means mounted on the connection piece of the cartridge is effected to thereby open the sealing member by means of a cutting means provided in the coupling means. The sealing member is opened at least to such an extent that it releases the flow path of the substance contained in the cartridge fully or partially due to the pressure exerted on the sealing member by the substance contained in the cartridge during an initial phase of the discharge operation.

Abstract: The invention relates to a beam for window frames or the like in which a spar for connecting to the beam has on its side facing the beam at least one slot extending in the direction of the longitudinal extension of the spar. According to the invention, such a beam is to be so constructed that a load acting on the window frame can be received more securely, and it should be possible for the beam to be produced more cheaply and to permit reliable sealing against moisture and better thermal insulation. This is achieved according to the invention if the beam (1) consists of two identical flat profiles (9) which are, however, arranged to form a mutual mirror image, having two hollow chambers (7, 8) which run parallel to one another at a distance and in the longitudinal direction and are each open to the outside by means of a longitudinal slot (6, 6'), the flat profile (9) having associated with each slot (14, 15) of a spar (13) at least one spacing crosspiece (10, 11) which can engage in the said slot (14, 15).

Abstract: An improved method and apparatus for powering and controlling the operation of large diesel-electric off-road haulers of the type in which hauler drive wheels are propelled and retarded by DC electric wheel motors powered from on-board generators, optionally supplemented by DC power, from external trolley lines. In the disclosed system, thyristor-type converters connected into the system AC power grid are used to receive supplemental external power from DC trolley lines and supply it into the AC power distribution grid in the propel mode. The use of such thyristor-type converters makes possible the use of supplemental trolley line power without provision of separate switching or control gear to operate the DC wheel motors when trolley line power is received. Thyristor-type converters also may be used to supply current generated by wheel motors in the retarding mode to retarding resistors, making possible the use of the initial electrical power generated by the wheel motors to replace load requirements of the diesel engine, resulting in substantial fuel savings.
