Abstract: PCT No. PCT/EP85/00502 Sec. 371 Date May 22, 1986 Sec. 102(e) Date May 22, 1986 PCT Filed Sep. 28, 1985 PCT Pub. No. WO86/02175 PCT Pub. Date Apr. 10, 1986.This invention relates to a process and a device for adjusting a photographic color enlarging or copying apparatus. By means of the measuring device that uses copying light of the enlarging apparatus to be adjusted as the measuring light, the color densities of a test copy made of a test original and of a reference copy which represents a satisfactory picture reproduction of the test original are measured selectively in the colors red, green and blue and are compared with one another. Corresponding to an existing deviation, adjusting control means at the enlarging apparatus that color-selectively influence the amount of copying light are readjusted until the deviation is balanced, and another test copy is made with the new exposure conditions and is measured.

Abstract: Axially-extending troughs (22) in a bark (18) of an internally threaded collar (10,200) receive setting balls (32) of a driver (30) that apply a torque to the collar (10,200) through the balls (32) bearing on the walls of the troughs (22). At a predetermined pre-load, the balls (32) fail the bark (18) and plow through it to develop circumferential furrows (114,206,208), and the torque application on the collar (10, 200) ends. A second torquing with balls (32) at a different axial plistion fails the bark (18) again at the same pre-load to compensate for any relaxation after the first torque application.

Abstract: The present invention is related to a liquid fuel rocket engine of the type that a liquid fuel is boosted in pressure by way of a booster means, thus-boosted liquid fuel is gasified within a fuel cooling jacket of a fuel combustor means with an expansion pressure of thus-gasified fuel being adapted to energize the booster means, and the gasified fuel is sent to the fuel combustor means so as to be combusted therein to produce a combustion gas to be discharged outwardly serving as a propulsive effort of the rocket engine. An expansion nozzle cooling jacket means is arranged around the circumference of a high expansion nozzle. 
     Part of the gasified fuel from the combustor cooling jacket means is directed into the expansion nozzle cooling jacket means to be reheated therein resulting in an increased potential energy to be utilized for driving the booster means. The remaining major part of gasified fuel from the combustor cooling jacket means is fed directely into the combustor means, so that it may be combusted to be discharged as propulsive force so pressure loss of the gasified fuel Is held to a minimum, while establishing a potential energy made available for driving the booster means.

Abstract: An apparatus for selectively feeding measured lengths of at least two different weft threads for the weft thread carriers of a multiple shed loom with pneumatic weft thread supply has a rotatably mounted revolving measuring drum (3) to which is assigned, for each weft thread, a pressure roller (11) which is adjustable between an inactive rest position and an operating position. In the operating position, the respective pressure roller presses against the circumferential surface of the measuring drum, and the associated weft thread (18) is conveyed. The pressure rollers have all been pretensioned individually in the direction of their operating position by one pretensioning force at a time, and are arrestable by actuators (28, 22) in their rest position from which they are releasable by selective actuation of the actuators. Moreover, the pressure rollers (11) are associated with a return device (30) which is controlled as a function of the movement of the weft thread carriers and which returns the pressure rollers into the rest position by ending the weft thread feed. <IMAGE>

Abstract: Matériau composite lié grâce à la réaction d'un nitrure de silicium et de zircone en utilisant du zircone non stabilisé. Les matériaux ci-décrits possèdent une bonne résistance et un retrait limité pendant la production, ce qui permet de réduire au minimum les opérations d'usinage de finissage. Ces céramiques binaires se composent de 10 à 80 % de nitrure de silicium. Ces matériaux permettent de résoudre les problèmes posés jusqu'à présent par l'adhérence de revêtements de zircone sur un matériau céramique en vrac. Le silicium et la zircone en poudre sont mélangés et ensuite compactés, et cette poudre compactée est chauffée dans une atmosphère d'azote. La phase de nitruration est un processus multi-étape au cours duquel la poudre compactée est successivement chauffée a) pendant 10 heures à 1150°C, b) pendant 5 heures à 1200°C, c) pendant 5 heures à 1250°C, d) pendant 10 heures à 1300°C, e) pendant 60 heures à 1350°C et finalement f) pendant 10 heures à 1425°C. De manière avantageuse la céramique composite possède au moins de 18 à 20 % de nitrure de silicium, étant donné que l'on a découvert que ces matériaux ne présentent pas de retrait lors de la liaison du nitrure de silicium par réaction pendant la phase de nitruration. Outre la bonne résistance et la stabilité dimensionnelle dans la plage mentionnée de proportions de nitrure de silicium, ces matériaux présentent des conductivités thermiques beaucoup plus faibles que celles des céramiques à base de nitrure de silicium lié par réaction ou à base de nitrure de silicium fritté et comprimé à chaud, ce qui permet de les utiliser à la place des céramiques à base de zircone lorsque des propriétés de faible conductivité thermique sont requises.
