Abstract: A variable reluctance transducer includes a C-shaped assembly (10) defining a magnetic circuit, one limb of the C being longer than the other. The assembly (10) is arranged with its limbs on opposite sides of a movable member (16). A winding (14) linked to the magnetic circuit is connected to a discriminating circuit including an integrator (A, R, C) having a variable bias circuit (D1, D2, R3, R2, C2, C2, A2, R4) which ensures that the peaks of the integrator output are in a predetermined relationship to a reference voltage. A comparator (A3) compares the integrator output with the reference voltage.

Abstract: A rotary piston machine, in order to avoid losses due to compressed flows, has adjacent to a generating and/or sealing contact edge (21, 22) at least one recess (11a, 11e) and/or opening (12a, 12b) which extends beyond the contact curve (14a-14c) in at least approximately the direction of motion of the surfaces moving in relation to each other during the stroke or passage of the piston (6a'') through the shut-off driver. The spatial dimensions of the recesses and/or opening are such that the flow in it is not substantially accelerated even when the direction is changed. An opening (11g, 11g') can be closed insofar as it is located in a nonmoving ring (6b). To prevent low pressures between surfaces moving away from each other (9c, 14c) a pressure compensation space (11e) is connected to the contact line (14c) of one of the surfaces.

Abstract: The system has a flexible internal structure, protected from and effectively invisible to users, with multilevel control and stack mechanisms and the capability of performing multiple, concurrent operations, and providing a flexible, simplified interface to users.. The system comprises a plurality of separate, independent job processors (10114) and a memory (10112). Each processor includes a fetch unit (10120) and an execute unit (10122) and the fetch unit structures operands and instructions into objects. The fetch unit includes a register address generator generating unique and permanent identifier codes for the objects. The memory (10112) includes sections storing procedure objects, including a name table providing the operand addresses in the memory. The memory (10112) also includes protection tables for preventing a user obtaining access to objects private to others. The protection tables operate in association with a protection cache in the fetch unit (10120) and an active subject number register which stores a currently active number identifying the user, the procedure he is using and the type of operation instructed. The protection tables store an access control list establishing the access rights,of the subjects and the protection cache in the fetch unit (10120) controls access to the objects by comparing the currently 'active subject number with the requested object. The fetch unit includes a descriptor processor performing the opera-  I  tions required by the instructions and first and second microcode control means storing first and second sequences of microinstructions for controlling the descriptor processor, the first sequences being S-language instructions which have a uniform, fixed format in an intermediate level language.

Abstract: Zur Herstellung von mit Kunststoff beschichteten sanitären Papierbahnen mit einem tiefen rechteckigen oder rautenförmigen reliefartigen Prägemuster werden die sanitäre Papierbahn und eine Bahn aus im plastischen Zustand befindlichen Kunststoff zusammengebracht und fortlaufend unter Anwendung von Druck zwischen einem Prägewerkzeug und einer elastischen Abstützung mit dem Prägemuster geprägt und verbunden. Dabei wird von der Seite der Kunststoffbahn her gekühlt. Um in einfacher Weise eine vollflächige Verbindung der Papierbahn mit der Folienbahn zu erreichen, wird die Kunststoffbahn extrudiert und in von daher plastischem Zustand verwendet. Das Prägen wird von der Seite der Kunststoffschicht mit auf dieser Seite angeordnetem Prägewerkzeug vorgenommen, wobei das Relief des Prägewerkzeugs so ausgebildet wird und das Prägen so erfolgt, daß auch der Reliefgrund des Prägewerkzeugs den Kunststoff mit noch ausreichendem Druck gegen die auf der elastischen Abstützung abgestutzte Papierbahn andrückt und die beiden Bahnen sich so im wesentlichen vollflächig miteinander verkleben.

Abstract: A cache memory system is described that reduces cache interference during direct memory access block write operations to main memory. A control memory 36 within cache contains in a single location validity bits for each word in a memory block. In response to the first word transferred at the beginning of a direct memory access block write operation to main memory, all validity bits for the block are reset in a single cache cycle. Cache is thereafter free to be read by the central processor during the time that the remaining words of the block are written without the need for additional cache invalidation memory cycles.

Abstract: @ A coupon (10, 12) is bonded to a component (20) using a bonding agent which is capable of withstanding temperatures only up to a selected temperature above which the bonding agent no longer holds the coupon to the component. The component (20), during an operation, is intended for exposure to temperatures not above the selected temperature. An exposure of the component (20) to the elevated selected temperature is identified by the fact that the coupon (10, 12) is no longer bonded to the component after termination of the operation. When the component (20) is provided with insulation, the selected temperature is chosen to correspond to a temperature at which the insulation fails to determine the integrity of the insulation after the operation. The coupon (10, 12) may be bonded to an exterior or interior surface of the component. With an exterior bonded coupon, visual inspection is sufficient. With an interior bonded coupon, detection means such as ultrasonic instrumentation is utilized to determine the presence or absence of the bonded coupon.

Abstract: A process and composition for applying and bonding an amine curable polymer or prepolymer at ambient temperatures to the surface of a cured elastomer substrate. The elastomer article or substrate is treated with an organic oxidant such as an N-halohydantoin, N-haloamide, or an N-haioimide, for example, the various isomers of mono-, di-, and trichloroisocyanuric acid. A polyisocyanate is applied thereto. A composition of the amine curable polymer or prepolymer is prepared with an amine curing agent. To the curing agent and curable polymer or prepolymer composition is added a polar solvent which is mixed with the resulting blend or mixture and added to the treated elastomer surface; said polymer or prepolymer cures at ambient temperature and becomes bonded to said elastomer. The application is relatively easy, since the entire mixture is a liquid and can be applied in situ. The invention is particularly suitable for repairing various damaged elastomer articles such as tires (especially off-the-road), conveyor belts, hoses, preparation of caulking or sealing compounds, and especially in bonding tire lugs or tire treads to a tire carcass.

Abstract: A method of bonding a metal body to a ceramic body,particularly a method of bonding a TWT slow-wave helix (11)  !  to boron nitride support rods (13), involves depositing on one of the bodies an active metal layer, typically oftitanium, to be sandwiched between barrier layers protecting it from oxidation. The assembly is formed and then heated to a temperature sufficient to cause the active metal to migrate into the surface of the ceramic, whereupon the temperature is further raised to cause the protective barrier layers to form a braze (14) uniting the metal body to the now-metallised ceramic body.
