Date Apr. 4, 1991.An aluminosilicate gel containing an ST structuring agent whose composition is suitable for crystallization into a zeolite of the faujasite structural family is prepared. The gel then undergoes crystallization in order to form a zeolite precursor which consists of the zeolite containing the ST structuring agent in its cavities and channels, the zeolite being produced through the calcination of the precursor. The ST structuring agent consists of at least one compound from the alkylene polyoxides of formula (1) <IMAGE> (I)  in which R and R', identical or different, each represents H or an alkyl radical in C1 to C4, X designates H or OH, m is equal to 2 or 3 and can differ from one pattern to another, and n is a number from 1 to 12. The zeolites thus obtained have a Si:Al ratio which is greater than 1 and which can go beyond 3, and show a cubic symmetry. The zeolites can be used, directly or after cation exchange, as adsorbants or as catalyst constituents.

Abstract: An instrument for measuring the respiratory capacity (pneumotachometer), consisting of a housing (1, 12) having two openings (14, 11) for the inlet and outlet of expired air, as well as a spring-loaded swivel arm (3), which is mounted rotatably in the housing and can be moved by the tidal air and whose swivel angle is displayed by a connected pointer/scale measuring device (9, 10), is to be improved to the effect that no initial build up of pressure is required and that the progressive enlargement of the width of the passage for the expired air occurs not at the outlet end of the instrument but in its interior, so that given a constant size of the outlet opening from the start onwards it is not possible for the movement of the air flow to build up in the instrument. This is achieved when the housing - apart from an inserted funnel-shaped mouthpiece - is constructed in the shape of a cuboid, the openings for the inlet and outlet of the expired air are arranged in two opposite housing walls, and the swivel arm projecting into the air throughflow channel is dimensioned so large that in its starting position (zero-point position) it does not completely seal the free cross-sectional surface of the air throughflow channel. <IMAGE>

Abstract: A metallization system for an integrated circuit is disclosed. This metallization includes a film of an alloy of aluminum, copper and silicon (16), which is sputtered onto the surface of a wafer having active semiconductor elements therein, to provide an interconnection. A barrier layer (14), for preventing the diffusion of metal atoms such as aluminum into the underlying silicon, can be provided under the aluminum alloy film (16). It has been observed that the presence of copper in aluminum metallization, while reducing the electromigration failure rate, increases the susceptibility of the aluminum film to corrosion. Doping the aluminum with silicon, in addition to the copper, has been observed to reduce the corrosion susceptibility of the aluminum alloy film.

Abstract: An eye movement analysis system injects imaging light (6) to an eyeball (3) for a time duration ( o ) short enough so as not to create blurring. Image data is then recorded (20) onto a recording medium. The image data is then read out of the recording medium and used to calculate (22) positional data concerning the eyeball's present location. At a later time, image data of the eyeball is again recorded in the recording medium and read out to calculate positional data concerning the eyeball's new location. The two sets of positional data are used to calculate eye movement data for use in diagnosing the causes of vertigo and/or disequilibrium.

Abstract: The invention relates to a transmission system for transmitting packets which comprise an information word group and a control word group, the control word group comprising an identification of the packet type (such as an identification of the virtual transmission channel and/or of the group of virtual transmission channels via which the packet is being transmitted), which transmission system comprises access control means for granting or refusing packets access to the part of the transmission system situated downstream of the access control means, depending on the incoming volume of packets. The invention provides for recording packets not admitted to the downstream part (T) of the transmission system by the access control means (2, 3) by an error reporting device (4). Preferably, provision is made that the error reporting device (4) for the packets not admitted records the number for each packet type (vci), and moreover, that the error reporting device (4) delivers an error report (c4) as soon as the number of packets not admitted exceeds a particular threshold value for a packet type.
