Abstract: Un echafaudage mobile possede une plateforme de travail reglable verticalement et des jambages disposes par paire consistant chacun en deux parties mobiles l'une par rapport a l'autre. L'un des problemes relatif aux echafaudages de travail de ce type reside dans le montage et le demontage qui sont difficiles et prennent du temps; en grande partie ceci est du au fait que les echafaudages connus consistent en un nombre relativement important de pieces qui doivent etre assemblees et demontees a chaque fois que ces derniers doivent etre montes et demontes. De maniere a resoudre ce probleme la presente invention propose qu'un cric (16) soit dispose entre les parties superieures et inferieures des jambages (10) de chaque paire de jambages au moyen duquel la plateforme de travail (3) est elevee et abaissee et que des etais detachables (23, 24) de maintien des paires de jambages soit disposes entre la plateforme de travail (3) et les parties superieures (10a) des jambages, une charniere (11, 12) etant prevue pour leur liaison avec la plateforme de travail de facon telle que la jambe (10) puisse pivoter autour de la liaison vers la plateforme de travail (3) apres desserrage au moins partiel de ladite liaison.

Abstract: A gear cutter (1) for cutting crown wheels and similar gears has a number of cutting edges (4) which project in the axial direction. After each edge has made its working stroke it passes under a brush (15) which removes any swarf which may adhere to it. The brush is free to rotate on a horizontal arm (12) clamped to a pillar (10) so that the position of the brush can be adjusted to suit the position of the cutting edge.. Swarf adhering to a cutting edge may damage the surface of a gear tooth during the following working stroke. The brush eliminates this risk.

Abstract: This invention relates to hot bending a metal pipe to small radius, and especially relates to the method to keep heating temperature substantially constant while radius of bending is changed gradually from large to small at the start and from small to large at the end of bending in order to make change of pipe wall thickness very gentle and smooth. 
     In orderto change radius of bending graduallythe ratio of relative speed of heater to the pipe to angular speed of bending is changed gradually, and then the method to keep heating temperature constant is required, 
     Two methods are given for it, one is to keep ratio of relative speed of heater to the pipe to heating power supply constant and the other is to keep each of them constant separately.

Abstract: Bei dieser Rückströmsperre ist wie bei bekannten Rückströmsperren auf dem Schneckenkopf (3, 24) zwischen einem vorderen und einem hinteren Anschlag ein frei verschiebbarer Druckring (6, 21) vorgesehen, der mit seinem Außenumfang an der Zylinderinnenwand (1) geführt ist, an seinem Innenumfang einen Durchlaßspalt (11, 36) für das zu verspritzende Material frei lässt und dessen mit dem hinteren Anschlag zusammenwirkende Fläche als Dichtfläche (9, 35) ausgebildet ist. Um insbesondere bei der Verarbeitung von dünnflüssigen Materialien ein rascheres Ansprechen der Rückströmsperre ohne Masseverluste zu ermöglichen und stets ein konstantes Schußgewicht zu erhalten, ist nach der Erfindung diese Rückströmsperre so ausgebildet, daß im vorderen Bereich des Druckringes (6,21) ein den Durchlaßspalt (11, 36) gegenüber einer Rückströmung verschließendes Rückschlagventil (14,22) angeordnet ist. Das Rückschlagventil kann eine Ringscheibe (14) oder ein Ventilring (22) sein, die aufgrund ihrer im Verhältnis zum Druckring (6,21) geringen Masse erheblich schneller beim Spritzhub der Schnecke (2) in die Schließstellung gelangen und den Massestrom nach hinten absperren.

Abstract: Method and apparatus for treating fibrous plant material, preferably straw, with aqueous alkali solution, preferably soda lye. The straw is supplied at the bottom of a container (1) filled with aqueous alkali solution which is characterized in that it has no uniform alkali concentration but an alkali gradient such that the alkali concentration is highest at the bottom of the container (1) and lowest at the top thereof. While rising upwardly in the container by its own buoyancy, the straw is thus treated with aqueous alkali solution of successively decreasing concentration. Finally, the straw is removed from the top of the container (1) and flushed, ln the flushing operation only so much fresh flushing water is supplied as corresponds to the liquid absorbed by the straw. As a result, a closed system in respect of thetreating liquid will be obtained. The container has supply means (2) for supplying plant material (3) and lye of high concentration (5) at the bottom and a grid (9), conveying means (11) and flushing means (13,16) forthe plant material at the top. Besides, the container has at least one levelling vessel (17) between the top and the bottom for adjusting the liquid level in the container upwardly and downwardly by supply and withdrawal, respectively, of liquid and resultant control of the level of the straw column in the container.
