摘要： A multi-bladed propeller and shaft assembly is provided in which air can be fed to the propeller blades to reduce the effects of cavitation. A shaft (10) leads to a multi-bladed propeller (15) and carries a sleeve (18) formed with inlet passages (20) and axial and radial passages (21, 24) leading to the respective blades (17). A slip ring (45) supported in an anti-rotation device (62) allows the shaft sleeve (18) to rotate within axially spaced bearings (46, 47) of the slip ring (45). Axially spaced air seals (49, 50) together define with the body (48) of the slip ring an annulus (51) within which inlet passages (20) rotate. Each seal (49 or 50) is formed as a multiplicity of arcuate segments (80) resiliently biased towards the sleeve (18) and having movably selaed end face portions (81, 82) to maintain pressure tightness. The body (48) further has a radial flow passage (57) for admission of air under pressure to the annular space (57) and a flexible fluid connector (56) connects the radial flow passage (57) to an air supply line (54) leading from the hull structure. The present shaft delivery slip ring avoids the need to feed air down the whole length of the propeller shaft or to feed air into the hub through a slip ring making wiping contact with the hub, which is structurally more complex.

摘要： A thermal sleeve for a gun barrel is in the form of a cylinder of a substantially rigid thermally insulating material (2,4,6) with a series of longitudinally and circumferentially spaced spacer members (20) disposed on the inner face of the cylinder. The spacer members (20) engage with the gun barrel and define an annular gap between the cylinder and the barrel. The sleeve (18) further includes means (28) for sealing the annular gap as well as means (32) for securing the cylinder on the barrel to ensure pressurised contact of the spacer members (20) with the barrel.

摘要： @ A plate is prepared by uniformly coating a substrate with a powdered material which is capable of being melted by the action of laser light. The plate is then image-wise exposed with a laser to melt the coating in selected areas. The exposed plate is used in lithographic printing plate manufacture. Thus the non-melted powder may be removed from the substrate to leave a lithographic printing image constituted by the laser light struck areas of the plate. Alternatively, the non-melted powder may be transferred and fixed to a transparent substrate which is then used to expose radiation sensitive material to form a lithographic printing plate.

摘要： A photoconductive composition comprises a photoconductor and a sensitiser. The sensitiser has the formula
wherein R represents alkyl; R1 represents H, alkyl or aryl; R2 represents the atoms required to complete a hetero or carboxyclic ring ; A represents an anion ; and n represents the valency of the anion. The composition is sensitive to both laser light sources and tungsten light sources and is useful in electrophotographic reproduction.-

摘要： Changes occurring in the electrical conductivity of liquids used to process image-wise exposed radiation sensitive devices are used as a measure of the deterioration in effectiveness of the liquids. This deterioration is compensated for by varying the processing conditions, such as temperature, time, scrubbing action and processing liquid composition, in accordance with the change in conductivity.

摘要： On décrit un système de commande de stabilisateur amélioré à aileron, qui comprend un système de commande automatique de gain (CAG) utilisant la différence entre les ordres établis selon des lois de commande et les angles réels de l'aileron pour calculer un facteur de gain et réduire le niveau des signaux d'ordre jusqu'à ce que les non-linéarités aient pratiquement disparu. Si plus d'une loi de commande est utilisée pour générer un ordre, les lois de commande peuvent être hiérarchisées et la puissance d'actionnement disponible est ainsi repartie de façon mesurée. En particulier, le sous-système de commande automatique de gain (CAG) de chaque loi de commande surveille les mouvements des ailerons afin de détecter, pour chaque aileron, si celui-ci obéit ou pas aux ordres des lois de commande. Il ajuste le gain de la loi de commande de façon à réduire les effets dus aux limites de vitesse de pivotement et d'angle d'aileron. Bien que le sous-système de commande automatique de gain permette de réduire le gain de la boucle de loi de commande, il limite les mouvements du bateau davantage qu'une loi de commande classique, parce que le retard de phase entre les angles d'aileron commandés et les angles réels est ainsi diminué et que la génération des harmoniques de l'angle d'aileron commandé est aussi considérablement diminuée.
摘要翻译： 一种改进的副翼稳定器控制系统，它包括一个自动增益控制（AGC）系统，利用根据控制规律建立的指令之间的差异和副翼的实际角度来计算增益系数。 并降低命令信号的电平直到非线性实际上消失。 如果使用多个控制律来生成订单，则可以对控制法进行分层，并且可用的操作功率以一种可测量的方式进行分配。 具体而言，每个控制法则的自动增益控制（AGC）子系统监视鳍的移动，以便为每个鳍检测其是否服从控制法则的命令。 它调整控制律的增益，以减少由于旋转和飞角的速度限制所造成的影响。 尽管自动增益控制子系统允许减少控制律回路的增益，但它比传统的控制律更限制了船的运动，因为相位滞后 因此减小了实际角度，并且受控机翼角度的谐波的产生也大大减少。

摘要： A printing press comprises a rotatable cylindrical surface (6) carrying a gravure printing image and ink is applied to the surface by an inking unit comprising a pressurised ink duct. The ink duct is bounded by the surface (6), a doctor blade (12) and a sealing member (11). ink is supplied to the duct under pressure from a source and excess ink is returned to the source. The image may be on a plate mounted on a plate cylinder (6) in a readily removable manner. The press may be produced by conversion of a letterpress printing machine for newspaper production.
