Abstract: The invention relates to a distance-dependent control valve (77), particularly for controlling a belt brake. The piston rod (65) of an hydraulic cylinder (63) is displaceable against the action of a spring (95) and connected to a control rod (45) which is applied to a belt brake (11). The control valve (77) comprises a control slider (97), the position of which within the valve is determined by an equilibrium of forces between a pressure signal and a spring force. The latter varies in dependence on the cylinder actuation. By controlling the position of the control slider (97), pressure fluid can enter in a controllable volume into the hydraulic cylinder (63) or flow out of it, in such a manner that the actuation of the hydraulic cylinder (63) is dependent on the variations of the said pressure signal. <IMAGE>

Abstract: A fluid drop recording apparatus generating multiple drop streams (2) is described in which at least every other deflection electrode (19, 20, 21, 22) includes a gutter or drop collection device (28) inside the electrode (19,21). Associated with each of the multiple drop streams (2) is a pair of deflection electrodes thereby leaving minimal lateral and forward space for the gutter device (28). The gutter (28) is hidden. That is, the mouth to the gutter faces downstream and is not accessable by drops in flight. Rather, drops first impact collision surfaces (35, 36) on the sides of a gutter deflection electrode (19, 21). The resultant fluid surface stream flows around a curved end surface (43) of the gutter deflection electrode (19, 21) and enters the gutter (28) through the downstream facing mouth.

Abstract: A rinse conditioner containing cationic surfactant and optionally other surfactants or fatty materials is prepared to relatively high viscosity at which it is stable. The process step necessary to achieve this is first to prepare a relatively mobile dispersion of the active materials and to thicken this mobile dispersion with a nonionic or weakly anionic thickener.

Abstract: Die Erfindung betrifft ein Verfahren zum Zuführen von Garnen mit verschiedenen Farben (a bis d) zu einer konventionellen Strickmaschine (1) zur Herstellung gestreifter Waren (Ringelwaren). Der erste verfahrensgemäße Schritt besteht darin, daß in Abhängigkeit von dem gewünschten Streifenmuster ein vorbestimmter Längerabschnitt in einer Garnfarbe ausgewählt und bereitgestellt wird. Danach findet eine Verbindung der Längenabschnitte, die zuvor ausgewählt und dargeboten wurden, zu einem fortlaufenden Garnstrang (7) statt. In einer dritten Verfahrensstufe wird aus dem fortlaufenden Garn aus zusammengesetzten Abschnitten intermittierend ein Zwischenvorrat gebildet, aus dem in einem vierten Verfahrensschritt das Garn der Strickmaschine (1) positiv zugeführt wird, d.h., mit einer konstanten Geschwindigkeit, die mit der Antriebsgeschwindigkeit der Strickmaschine synchron ist. Das Zuführen des ununterbrochenen Fadenstranges erfolgt bei dem jeweiligen Stricksystem (3) der Maschine. Das Verbinden der unterschiedlichen Garnlängsabschnitte zu einem fortlaufenden Garnstrang wird synchron mit den Arbeitstakten der Strickmaschine (1) ausgeführt, so daß der Zwischenvorrat mit einer Geschwindigkeit gebildet wird, die mit dem Garnverbrauch pro Maschinenumdrehung der Strickmaschine korrespondiert. Es können dabei die Verbindungsstellen zwischen den Garnlängsabschnitten mit hoher Genauigkeit so plaziert werden, daß sie bei jeder Umdrehung der Strickmaschine (1) im selben Bereich (16) des Nadelbettes (1a) zu liegen kommen. Die Erfindung ist auch auf eine Vorrichtung zum Durchführen des Verfahrens gerichtet.

Abstract: An optical storage medium for storing binary data adapted to be written upon by a laser forming an array of encoded spots is composed of a substrate (10) preferably covered with a mirror layer (15) and including a matrix of a transparent dielectric material (14) such as a polymer upon which a vacuum deposited discontinuous film (11) on nucleated metallic islands is deposited having thicknesses of less than about 100. The particles extend up to 1000 A transversely generally parallel to the surface of said substrate (10). The islands are separated by a short distance for facilitating coalescence of particles together to effect writing of spots at low energy by the lateral motion and gathering of the Islands during heating of the islands by a laser beam or the like. Each spot represents a data bit in a binary position code. The matrix material has low thermal conductivity and preferably a low melting point to facilitate writing at low energy.

Abstract: A method of extending the lipid content of a grown microbe comprises treating the microbe with an organic lipid-extending substance so that the substance is absorbed by the lipid and is retained passively in the microbe. An encapsulated material may be produced by treating a grown microbe with the lipid-extending substance and a material which is soluble or micro-dispersible in the substance. Suitable substances may be selected by tests stated in the specification. Examples of substances are some liquid alcohols, esters, aromatic hydrocarbons and hydrogenated aromatic hydrocarbons. The method is particularly suitable for producing encapsulated dyes for use in carbonless copy paper.

Abstract: The present invention provides a method of electric discharge machining by means of a wire electrode for cutting a workpiece into a commanded shape by producing an electric discharge between the workpiece and the wire electrode and moving the wire electrode relative to the workpiece along a commanded path. The method includes steps of previously storing, in a computer memory, sets of machining conditions which differ depending upon workpiece material and thickness, reading out of the memory a predetermined set of the machining conditions in response to a machining condition selection instruction issued in a machining program at the time that the workpiece is being machined, and performing electric discharge machining in accordance with the read set of machining conditions. The invention also provides a control device operable to produce the method. The machining is carried out on an electric discharge machine (107) and the control device comprises a processor (103) and a memory (106) in which the sets of machining conditions are stored. Machining is controlled by the processor (103) in dependence upon a paper tape (101) fed into a tape reader (102).

Abstract: Nouvel immunogène pouvant être utilisé pour la protection immunologique contre les maladies diarrhéiques aiguës provoquées par des souches entérotonigènes d'Eschérichia coli. Le nouvel immunogène est obtenu par réticulation de l'antérotoxine stable à la chaleur de l'Eschérichia coli avec l'entérotoxine instable à la chaleur de l'Eschérichia coli (soit l'holotonine complète soit uniquement la sous unité B de cette toxine) par un procédé de conjugaison en présence d'un agent de conjugaison, d'une manière caractéristique le carbodiimide soluble dans l'eau, le 1-éthyle-3-(3-biméthyle aminopropyle) carboiimide. Ce procédé permet d'obtenir une nouvelle molécule se caractérisant en ce que les propriétés toxiques de chaque toxine individuelle sont sensiblement réduites, la toxine instable à la chaleur (ou sa sous unité B) garde son antigénicité, et la toxine stable à la chaleur acquiert une immunogénicité en fonction de la réaction. L'immunisation au moyen de l'immunogène réticulé confère une protection immunologique aux mammifères contre la sécrétion d'eau induite par des souches d'Eschérichia coli qui produisent les entérotoxines instables à la chaleur ou stables à la chaleur, soit séparément soit ensemble.
