Abstract: An improved annular seal includes a resilient seal ring (32), a first follower (36), a second follower (38) threadedly connected to the first follower, threads (44) on the first follower for setting movement of the followers, and a shear pin (40) for releasably securing the second follower to the first follower. The first follower (36) has a lower rim for engaging the resilient seal rings (32) and, the second follower has a lower extension (64) for exerting a loading force on the resilient seal ring. The area of engagement of the first follower (36) with the seal ring is substantially larger than the area of the second seal ring exerting the seal ring loading force. In one form the second follower includes a lower rim extending around the exterior of the first follower into engagement with the seal ring. In a modified form the first follower includes a plurality of openings through its lower rim and the second follower includes a plurality of pin ends extending in the openings to exert a force on the seal ring.

Abstract: An apparatus for mixing materials, including a fluid, in a vessel (20), which apparatus includes a hollow elongated shaft (22) mounted so as to be driven at one end (30) for rotation about its longitudinal axis within the vessel, the other end (28) of the shaft in the vessel being open. A planar baffle plate (40) extends across the vessel intermediate the ends of and transversely to the shaft so as to divide the vessel's interior into two zones joined by the fluid pervious clearance (42) around the edge of the plate. The open end of the shaft (28) is located in one of the zones (38); the walls (46) of that portion of the shaft located in the second of the zones (36) are perforated (54) to permit fluid flow between the second zone and the shaft interior. A turbine impeller (56) is also mounted on the shaft adjacent the open end (28) of the latter so as to be rotatable with the shaft for creating a relatively low pressure in the volume of materials and fluid disposed immediatly adjacent the open end of the shaft.

Abstract: A known portable data carrier (D) exhibits a visual display area which can be driven by the terminal and which is constructed as liquid-crystal display. Without energy supply, the display is only retained for a short time in a liquid-crystal display. According to the invention, the visual display area (AZ) is constructed as a foil with a layer which can be changed into the transparent and, respectively, non-transparent state by means of different temperatures. If the read device of the terminal is provided with a corresponding deleting and writing device, the display area of the data carrier can be filled with information items which are retained for an unlimited time. The invention can be used in all conceivable chip and magnetic cards, in which residual units or residual amounts can be visually displayed for the user. <IMAGE>

Abstract: At the beginning of an address operation for a request to be executed, an identification code (TID) is generated and transmitted with the applied address (ADR) from the requesting subscriber (for example TN1) to all other subscribers via the line system (SPBUS). Each subscriber, even the transmitter itself, is provided with storage devices (BUFM,SYNC-QU) for accommodating the address transmitted in each case and the request identification code (TID) also supplied. At the same time, the addresses stored in the storage devices (SYNC-QU) are monitored in checking devices (for example CCAE-CTR) of the subscribers for assigning the line system (SPBUS) for further transmissions, and after all subscribers have been monitored, a synchronisation signal (SYNC) and, if necessary accompanying signals (SHA,INT,ABORT,ACT) are set for ending or continuing a request. When they are continued with a data operation, a correlation of the data operation with its corresponding address operation can be achieved by transmitting back the associated request identification code (TID) together with the data (DATA) to the requesting subscriber, which correlation allows data responses to occur outside the order defined by the initialisation of the individual address operations. <IMAGE>

Abstract: An optical particle analyzing apparatus includes a flow cytometer in which laser (10) light and lamp (26) light having a wavelength shorter than that of the laser (10) light are used simultaneously when particles in a blood specimen or the like are analyzed by the flow cytometer. Scattered light emitted by a particle due to irradiation with the laser (10) light and fluorescence emitted by the particle due to irradiation with the lamp (26) light are detected. A signal indicative of the scattered light is used as a timing signal to detect the fluorescence. This arrangement makes it possible to reduce the size and cost of the apparatus.

Abstract: The invention relates to a surgical device (1, 2) for applying wound staples (6), which consist essentially of two branches (7, 8) and a bridge (9) connecting the branches, and which are moved one after the other from a magazine (10) onto a bottom die (15) and can be deformed there using an upper die (19). The upper die (19) is lowered from a rest position in the direction of the staple (6) to be applied in each case and is displaced further in order thereby to close the staple, by bending it around the bottom die (15), and to insert the branches (7, 8) of the staple into the tissue. In order to achieve a perfect and symmetrical deformation of the staples (6), a holding-down device (18) is provided, which can be lowered onto the bottom die (15) and which, during the deformation of the staple (6) to be applied, presses its bridge (9) onto the bottom die (15) and prevents the staple (6) from being moved sideways on the bottom die (15) during the deformation process.

Abstract: By a method of fabricating an integrated circuit chip including insulated gate field effect transistors, a recess (106) may be formed in the chip under a photoresist layer (102) such that the photoresist overhangs the recess. A metal film (110) is cold-sputtered, filling the recess and covering the photoresist. The metal film in the recess (110) is separated from the metal film  (112) covering the recess because of the overhang. A second photo­resist layer (114) is applied, then etched to expose a corner of the metal film over the overhang. The metal is etched to expose the underlying photoresist (102). Finally the underlying photoresist (102), and the portion of the second photoresist layer (114) over the metal film (110) in the recess, are removed.

Abstract: An apparatus for inspecting vessels for the presence of foreign matter inspects the vessel as it undergoes a reverse rotation which follows a forward rotation. A receptacle on which the vessel is driven for rotation is mounted on a rotatable body for conveying the vessel along a circular path, and the receptacle is driven by a control motor for rotation about its vertical axis in the forward and the reverse directions. A controller which controls the control motor detects any change in the speed of conveyance of the vessel, and responds to such change by controlling the motor so that a given, predetermined permissible inspecting condition of the vessel is maintained in the presence of a change in the speed of conveyance of the rotatable body.

Abstract: Un circuit de mélange à fréquence intermédiaire (10) incorporé dans un récepteur sous forme de circuits intégrés, utilise une paire de mélangeurs à double équilibre (22, 46), l'un recevant un signal de référence local en phase pendant que l'autre mélangeur reçoit la phase en quadrature du signal de référence. Un circuit de décalage de phases (42) ajoute un décalage de phase de 90° à la sortie du deuxième mélangeur (46) et les signaux en phase et hors phase sont soumis à un circuit d'addition (40) pour atténuer les produits de mélangeur indésirables et renforcer le signal de fréquence intermédiaire recherché. Les éléments en équilibre du circuit de déphasage à 90° (42) emploient un transistor (61) doté de résistances égales pour l'émetteur et le collecteur, un transistor en série à une diode (63) avec la résistance de charge du collecteur (65) et une capacité collecteur à base (67) qui offre un décalage de phase d'amplitude constante dans une unité de structure de gain, indépendante du courant, pour produire un déphasage précis de 90°. Le courant de l'émetteur est réglable pour compenser la variation de la production en valeur absolue de la résistance fixe, par exemple, en faisant varier le courant dans le transistor et dans la diode la résistance dynamique déplace la variation de la résistance fixe.
