Inventor: KAPLAN J-P
IPC: C07D207/08
Filed: 1977-08-04
Abstract: The optically active pyrrolidines of formula: <IMAGE> are obtained from (R)- or (S)-glutamic acid, by formation of an aldimine with an aldehyde R''CHO, reduction of the imino group to an amino group, cyclisation by the action of an acid, esterification of the carboxyl, conversion of the ester to an amide and reduction. The compounds can be used in the synthesis of optically active benzamides, which have a therapeutic activity, of formula: <IMAGE> To this end, they are condensed with a 2-methoxy-5-X-benzoic acid or one of its derivatives. None of the reactions affects the absolute configuration of the asymmetric carbon; thus, (S)-glutamic acid leads to an (S)-amine I and to an (S)-benzamide II. The symbols R', R'' and X are defined in Claims 1 and 8.

Abstract: A hydraulic steering system has two steering conduits (3, 4) leading from a manually actuable steering valve (6) to the opposite ends of the steering cylinders (1, 2). A pressure medium actuator (29) can also actuate the steering valve in dependence on the operating pressure fed to each steering conduit (3, 4). A frequency-responsive hydraulic circuit (40, 43, 45-53) is interposed between the steering conduits (3, 4) and the actuator in such a way that only pressure oscillations above a pre- determined frequency, such as caused by rapid setting of the steering valve, are transmitted to the actuator, which in turn counteracts the manually chosen valve setting until the pressure oscillations have been dampened. <IMAGE>

Abstract: The gear machine, e.g. a gear pump, especially for high pressures, or a gear motor, comprises a ring gear (4) which is rotatably mounted in a casing (1) and has at least nine and at most fifteen teeth (6), and further comprises a pinion meshing with the ring gear. An approximately crescent-shaped filler piece (10) is provided which, on the pinion side, is bounded by the addendum surface (17) of the pinion and, on the ring gear side, is bounded by the addendum surface (15) of the ring gear. The tip diameter of the ring gear is smaller than that of the pinion. The pinion has two teeth (9) fewer than the ring gear. The cylindrical surfaces of the filling piece terminate at the end situated in the gear wheel revolving direction (36) in such a way, that the trailing edges of the crest of one tooth each of the ring gear and of the pinion simultaneously disengage at the corresponding addendum surface. As a result, the gear machine has a long service life and produces little noise. <IMAGE>

Abstract: A scarifier tooth assembly of the type used on earth excavation equipment for digging furrows in the ground which comprises a replacement point and a clamp member for securing the point to a conventional tapered and grooved shank carried by the bucket of the earth excavating equipment. The point is of a forged integral construction and includes a tapered forward digging portion and a shaft portion extending rearwardly therefrom. The shaft portion defines a flat lower bearing surface adapted to abut a flat bearing surface on the shank and a curvilinear upper bearing surface adapted to abut an interior curvilinear bearing surface of the clamp member. Ear members project laterally from the rearward most end of the shaft portion of the point and fit about the shank for preventing relative lateral movement between the point and shank. The clamp member is generally of an inverted "U"-shaped configuration and defines an inner curvilinear bearing surface and inwardly projecting lateral flanges at the open end thereof. Upon slighting the clamp over the point and shank, the projecting flanges fit within the locking grooves in the shank while the curvilinear bearing surface presses against the upper mating bearing surface on the shaft portion of the point, wedging and securing the point tightly between the clamp and shank.
