Patent EP-0012028-A1 (EP)
Inventor: LARSEN RAYMOND BARBER
IPC: F24S10/50
Filed: 1979-11-30
Abstract: A solar collector assembly (10) is capable of directing an extremely thin film of water in direct contact with a collector sheet (19), the film being formed and regulated by air cushion layers (20, 18 and 22) coextensive with the passage or course of water adjacent and in contact with the collector sheet; the pressure of the air cushion layers against the collector sheet and water film is closely regulated both by the pressure of air in the air cushion layers and the relative tension applied to the collector sheet and layers by the outer peripheral connector and frame assembly. A form of connector and frame assembly (16) has been devised to establish both the desired spacing and tension on the sheets (18,19,20 and 22) while permitting releasable but secure connection of the sheets and layers in place within the frame and simultaneously provide the necessary communication with water inlet and outlet headers (50,51:61,62) and air supply (40a, 40,41).

La chambre (112), qui est delimitee par des parois perforees (108, 110) interne et externe espacees coaxiales et cylindriques, tournent autour de l'axe longitudinal (119) des cylindres. La vapeur entre dans le lit, qui est maintenu a une temperature d'environ 1800 F., au travers de la paroi perforee externe et fluidifie les particules. Une chambre de combustion a lit fluidise en rotation peut etre combinee avec le gazeificateur. Dans ce mode de realisation l'air comprime et le charbon en poudre entrent dans le lit avec la vapeur au travers de la paroi perforee externe. Des conduits d'echange de chaleur (120) passent sensiblement longitudinalement au travers du lit fluidise en rotation. En cas d'utilisation avec des machines compound, les compresseurs (20) fournissent l'air comprime a la chambre de combustion et de gazeification et les gaz sortant du lit sont diriges dans des moyens d'expansion (22, 24).

Abstract: Data words encoded in a Bose-Chaudhuri-Hocquenghem (BCH) code are read from a document (14) and applied to a processor (26) and decoder (28) which check the word and correct errors therein, up to two errors being correctable in the embodiment described. Respective modules (46, 48, 50) compute power sum symmetric functions S 1 , S 2 , S 3  which are utilized to indicate the location of errors. To provide for the location of two errors, the value of S 3 /S 1  is calculated by utilizing a Galois field table (74, 76) arranged in an anti-log and log format. The Galois field table is also utilized in determining the location of a single error by utilizing S 1  as an anti-log. Errors which have been located are corrected by inverting the incorrect binary digit.

Abstract: An electromechanical scale 10 is disclosed comprising an outer ground support frame 12 and a weighing platform 14 suspended with the ground support frame by a cantilever mounted load supporting bar90. The load supporting bar has an upper 110, 112 and lower 114, 116 pair of strain gauges mounted on upper and lower surfaces 111, 115, respectively, of the bar and are vertically aligned and spaced a predetermined distance for sensing differential bending moments proportional to the applied weight of an article on the weighing platform. An articulated connection 100 between the weighing platform and the ground support frame transfers only vertical loading to the bar thus preventing extraneous loads from affecting the strain input to the gauges. The gauges are wired in a bridge circuit which has an output connected to an appropriate electrical read-out device.

Abstract: A parking tower (10) comprises a frame (11) which defines cubicles (12a-t) positioned one above the other and an elevator (16) attached to the frame (11) for conveying vehicles (36) vertically between a ground level and vertical positions adjacent to the cubicles (12a-t). Both the elevator (16) and the cubicles (12a-t) include horizontal conveyors for conveying vehicles (36) between the cubicles (12a-t) and the elevator (16). Controlling mechanisms are actuated at, or near, the ground level to cause a motor assembly (26) to move vehicles between the ground level and cubicles. The horizontal conveyors of the elevator (16) and the cubicles are driven by a motor on the elevator and are clutched together to provide driving linkages. Endless conveyors of the elevator (16) and cubicles (12) include rollers which are mounted on non- circular shafts that can be slid out of their U-shaped frames. A selectively-actuated wheel chock prevents rolling of a vehicle after it is placed on the elevator (16).

Abstract: Mit dieser Einrichtung soll der Zugriff mehrerer Mikroprozessoren auf eine Datenleitung gesteuert werden. Zu diesem Zweck sind die Prozessoren (CPU) über Interfacebausteine (IF), Logik-Schaltkreise (LS) und Bustreiber (BT) an zwei Leitern (SB-BREQ, SB-BAV) angeschlossen. Durch eine Zugriffsanforderung (BREQ) eines Prozessors wird ein Signalwechsel des ersten Leiters (SB-BREQ) hervorgerufen. Dieser Signalwechsel bewirkt die Umwandlung einer prozessorspezifischen Information in die Verzögerung eines Prioritätssignals, bei dessen Auftreten ein Signalwechsel des zweiten Leiters (SB-BAV) erfolgt. In Abhängigkeit davon tritt an einem Eingang (CTS) des Interfacebausteines (IF) ein die Verfügbarkeit des Datenleiters (SB-DATA) anzeigender Signalwechsel auf. Bei gleichzeitig eintreffenden Zugriffsanforderungen (BREQ) mehrerer Prozessoren wird der Signalwechsel des zweiten Leiters (SB-BAV) von demjenigen Prozessor verursacht, dessen Prioritätssignal die kleinste Verzögerung aufweist. Der Signalwechsel des zweiten Leiters (SB-BAV) verhindert das Auftreten der den übrigen Prozessoren zugeordneten Prioritätssignale mit größeren Verzögerungen. Bei diesen Prozessoren kann daher auch kein die Verfügbarkeit des Datenleiters (SB-DATA) anzeigender Signalwechsel am Eingang (CTS) des betreffenden Interfacebausteines (IF) stattfinden.

IPC: H01L23/48
Filed: 1981-04-14
Abstract: Gold is preferred as the conductor material in metallisation layer (4) of a semiconductor device because of its high conductivity and freedom from electromigration effects but gold is inclined to diffuse into the semiconductor substrate (1),typically silicon, so degrading the p-n junction characteristics within the semiconductor substrate and rendering the device inoperative. Previously this problem has been overcome by placing a protective barrier layer of titanium (3) between the gold layer (4) and the substrate (1). The gold/titanium interface is subject to corrosion and this corrosion adjacent the substrate (1) contrining the active areas of the device also leads to failure of the device. This is prevented by covering the gold metallisation layer (4) ofthe device on its top (5), bottom (3) and side surfaces (7) with titanium. This prevents the diffusion of the gold into any other layer (1, 2, 8) of the semiconductor device above or below it and there is no gold/titanium interface exposed adjacent any active area of the device.
