Patent EP-0000422-A1 (EP)
Inventor: HUNT GEOFFREY HAROLD
IPC: G02F1/139
Filed: 1978-06-15
Abstract: An optical screen (12) is provided which can be used in conjunction with a cathode ray tube (CRT) (10) to prevent the CRT display from becoming unreadable in high ambient light conditions (such as can occur in an aircraft cockpit). The screen includes a series of parallel strips (13) each of which includes a layer (18) of an electro-optical substance such that it can be made light absorbent or transparent by varying voltage applied to the strip. 
     In use (Figure 1) the screen is positioned in front of a display face (11) of a CRT with the strips aligned with the writing direction of a raster (14). The position of the raster controls (15, 16, 17) voltages applied to the strips to ensure that each strip is transparent when the raster is writing behind it. 
     The electro-optical substance is advantageously a liquid crystal material.

Abstract: 1. Process for the transmission of data signals between a central station and at least one of a plurality of data subscribers which are connected via a junction station to a common permanently connected transmission link within an envelope structured synchronous data network, wherein each data subscriber emits the data bits which are to be transmitted combined with two control bits (status bit and synchronising bit) as envelopes and wherein, following the analysis of at least one of the control bits, the junction station allows the data subscriber which is connected to the junction station in question to be switched through to the permanently connected transmission link, characterized in that in the junction station (VZA) the envelopes emitted from the data subscriber in question (DT1 to DT4) are input into a first storage arrangement (e.g. ES1) which is assigned to the data subscriber in question and from which only the data bits contained in the relevant envelope are transferred to a second storage arrangement (ZS1), that an analysis device (SA1) which is connected to the first storage arrangement (ES1) evaluates the status bits of the envelope contained in the first storage arrangement (ES1) in such manner that only in the presence of status bits which possess a predetermined polarity ("0" or "1") are the data bits contained in the second storage arrangement (ZS1) forwarded to the permanently connected transmission link, and that when the data bits contained in the associated second storage arrangement (ZS1) are forwarded, the analysis device in question (e.g. SA1) additionally controls the envelope-correct insertion of the control bits (status bit and synchronising bit) into the data bit flow (Fig. 1 and 2).

Abstract: The manufacture of material webs of foamed plastics generally takes place by extrusion of the material in tubular form, whereupon the material whilst it is still in soft condition is calibrated, that is to say expanded by means of a mandrel, so that the desired tube diameter and thus the desired material thickness is obtained. The material tube is then cooled and cut up axially and laid flat to a web. This manufacturing procedure gives a final product with uneven surface, since the pores and craters which the material surface presents will be enlarged when the tube is expanded. Moreover, the cooling as well as the contact pressure of the material against the mandrel will be varying, which further increases the uneveness of the surface and gives the material an uneven quality. A more uniform material surface and a more homogeneous material tube is obtained in accordance with the invention, in that the material tube (3) after extrusion is pressed, by means of compressed air introduced into the tube, against an outer calibration element (5) and is cooled at the same time, so that its temperature drops below the softening temperature of the material. In this way the cooling as well as the contact pressure can be controlled, and by imparting moreover a profiled surface to the outer calibrating element, a rational manufacture of a material web of foamed thermoplastics of good quality and uniform surface is made possible.

Abstract: Convertisseur de couple hydrodynamique muni de moyens de pontage. Le piston de commande (17) est soumis à la pression de l'enceinte (22) dans la position de la figure. Le fluide hydraulique alimenté par l'arbre de transmission (12) pénètre dans l'enceinte (22) par les passages (29 et 30) et dans la chambre de commande (24) par l'orifice calibré (23). La sortie (40) de la chambre de commande (24) est bloquée par l'électrovanne (42). La pression dans l'enceinte (22) est la même que la pression dans la chambre de commande (24). Le ressort (25) entraîne donc un déplacement du piston de commande (17) l'ensemble fonctionnant en convertisseur de couple. Dans la position inverse de l'électrovanne (42), la pression régnant dans l'enceinte (22) dont la sortie (43) est obturée s'exerce sur le piston de commande (17) à l'encontre de la force du ressort (25). La pression dans la chambre de commande (24) est basse et le serrage de la garniture (18) provoque le pontage.
