Abstract: The edge (16) of the mounting cup (4) is connected to the frame edge of the container frame (2) by beading. The mounting cup (4)  is composed of an inside partial mounting cup (13) and an outside partial mounting cup (14) and it has at least one opening (11, 12) to receive closures (10). In order to attach the closure, an edge (17), projecting from the plane of the mounting cup, is moulded onto the openings (11, 12). Compared to the known curved mounting cup, more space is achieved for the arrangement of several closures and the mounting cup (4) can be used, due to the double wall 13, 14, even at high propellant gas pressures.

The total reduction amounts preferably to 0.5 to 1.5%; the annealing is preferably carried out at a temperature in the range of 350 DEG C. to 380 DEG  C. and during a period of maximum temperature of 5 to 60 seconds. By means of this method rolled steel products, such as for example tension steels, can be made in a simple and economical way, which products have ductility and mechanical properties entirely meeting the demands required for construction.

Abstract: Improvement of multilayer paper quality in the wet working section of a paper machine entails at least two different quality pulps for paper strip mfr.; collection and recycling of dilute suspension drained from a screen in quite separate containers where at least most of a first pulp is drained through a first screen, corresp. for a second pulp and where the suspensions from each screen are separately gathered and reintroduced to the corresp. pulp i.e. paper layer.  The appts. for the implementation comprises: appts. and pipework for gathering the separate dilute suspensions in accordance with quality levels and pipework for the re-introduction of the suspensions.  Where a two-layer strip is formed by passing two pulp layers through a continuous double-sided screen, the gathering of the different dilute suspensions is carried out mainly in the screens' initial zone. In the formation of a triple layer sheet where the dilute suspension extracted from a first screen originates essentially from the outer layers it is reintroduced to them, while that from a later screen is reintroduced to the middle layer. The outer layers (S1, S3) can originate from approx. the same pulp and enclose a middle layer (S2).

Abstract: A clamp (1) serves for connecting webs (2) at the edges of form panels disposed in coplanar, side-by-side relation and has for this purpose two clamping jaws (4) urging these edge webs (2) together, each clamping jaw (4) having an 10 adjusting arm (5) which is at an angle thereto and is located at the jaw-end remote from the clamping point (4a). The adjusting arms (5) in turn have points for applying an actuating or adjusting element in the form of a wedge (9), these points of application on the two adjusting arms (5) suitably being combined to form a single point for applying the wedge (9). The wedge (9) can slide along between this point of application and the edge webs (2), suitably on the abutment (12) belonging to the clamp (1), and thereby can move the point of application and accordingly the adjusting arms (5) away form the lining skin (3) and thereby close the clamping jaws (4). For reasons of space and for proper guidance a curved wedge may be provided which is movable in the plane in which the clamping jaws (4) close.

Date May 23, 1996In acquisition devices for analog measured values (Ue1 . . . Uen), there is frequently the problem that the digital processor (P) of said devices has a restricted binary word length (WP), as compared with the word length (WP) of the measured values in digitized form (AMD(Uen)). To permit unmodified rapid acquisition and digital conditioning of the measured values (AMD(Uen)), binary factors (NF, KF, VF) are preferably provided separately for each measured value (AMD(Uen)), said factors (NF, KF, VF) being combined (Equation 3) to form an element (K) which is processed by the processor (P) at an update rate which is lower in comparison with a sampling rate which is used to update the measured values (AMD(Uen)). As a result, the processing speed of the processor can be increased. It is also advantageous to provide a binary displacement factor (VF), by means of which the element (K) is expanded in a counter and the product of the element (K) and the respective digitized measured value (AMD(Uen)) is expanded in a denominator. The binary displacement factor (VF) is selected in such a way that the digital combination of the product with the displacement factor (VF) in the denominator corresponds to a loading operation of higher-order bits of the product by the processor (P).

Abstract: Key distribution system for public key certificates. By a user A, registered at a server SV1, the public key of a user Y, registered at a server SV3, can be calculated from a public key of user Y signed with the secret key of SV3 ({Pky}SKsv3), a number of cross-certificates ({PKsv3}SKsv2, {PKsv2}SKsv1), and the public key (PKsv1) of server SV1. If the user must perform such a calculation himself, that would impose a substantial load on the processing capacity of his terminal. As an improvement, it is suggested, as a service to the users, to let the servers generate key certificates of external users not registered at the same server. The key certificates are thereto recertified into certificates which are digitally signed with the aid of the SK of the own server SV1 ({PKx}SKsv1) and are made available to the local users on request.

Abstract: The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem-solving abilities. The invention redirects the conventional approach of "characterizing the froth" to "measuring the froth characteristic." The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signals received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.
