Patent EP-0046689-A1 (EP)
Inventor: MCGINNIS HEBERT E
IPC: B65G15/34
Filed: 1981-08-25
Abstract: A belt conveyor system has a stretchable belt reinforced by a layer of stretch fabric (16) which includes crimped high strength warp cords (17) woven around transverse cords (18). Low strength warp cords (19) are woven around the transverse cords (18) in an opposite direction to hold the high strength cords (17) in the crimped condition prior to and during molding of the belt. Upon installation the belt is stretched at least 5 percent and the low strength warp cords (19) are broken. The high strength warp cords (17) are then straightened out which results in a substantial increase in the resistance of the belt to further stretching after installation on the conveyor.

Abstract: Un appareil de contrôle et d'indication (10) du niveau de la tension comprend un convertisseur tension/fréquence (12), un circuit de conditionnement d'entrée (16) qui décale les signaux de tensions reçus à partir de différentes sources de tension vers le même niveau d'entrée pour le convertisseur (12) qui produit alors un signal de fréquence de sortie proportionnelle, un micro-processeur (40) qui est programmé par logiciel pour produire des données de niveau de tension en réponse au signal de fréquence de sortie provenant du convertisseur (12), et un affichage (42) qui affiche une série de chiffres en réponse aux données de niveau de tension. Les appareils de l'art antérieur ne sont pas basés sur des microprocesseurs de l'état de la technique et nécessitent différentes conceptions lorsqu'ils sont couplés à des sources de tension différentes. La présente invention se base sur les microprocesseurs et possède le même circuit de conditionnement d'entrée qui peut être couplé à différentes sources de tension essentiellement dans le but d'indiquer des niveaux de tension de batterie sur des chariots élévateurs électriques.

Abstract: The light fitting is constructed in two parts, so that the part (1) supporting the reflector can be pivoted with respect to the fixed housing (2, 2') which accommodates the essential electrical components. As a result, it is also further possible to adjust the light cone on the mounting. It is advantageously possible for the two housing parts (2, 2') to be sealed with respect to one another in a dust and watertight fashion despite the pivotability. <IMAGE>

IPC: H01L29/267

Abstract: In a transistor capable of operation at very high speed, the emitter comprises an outer region (8) having a normal energy level for charge carriers of the higher mobility type (electrons) and an inner region (9) providing a barrier having a height greater than the aforesaid normal energy level and being sufficiently thin to permit the higher mobility charge carriers to quantum mechanical tunnel therethrough. The base (3) has an upper energy valley for the injected charge carriers substantially at the aforementioned normal energy level in the outer region of the emitter and is sufficiently thin to permit rapid transport therethrough of the injected charge carriers. The collector comprises an inner region (12) providing a barrier having a height at least as high as the upper energy valley in the base and an outer region (13) having a normal energy level for the injected charge carriers lower than the normal energy level for those charge carriers in the outer region (8) of the emitter. Because the injected charge carriers cross the base in an upper energy valley, the probability of energy loss is reduced. The switching time of the transistor is of the order of 10- 12  seconds.

Abstract: Gd 2 0 3  and Ga 2 0 3  are currently used for the fabrication of Gd 3 Ga 5 O 12  (GGG) wafers which are employed as substrates for bubble domain memory devices. In the processing, in the order of 25% of the starting material ends up as process "saw kerf" contaminated with variable amounts of iron, nickel, magnesium aluminum, zirconium, iridium and silicon. 
     The process "saw kerf" produced from slicing the crystal boule is dissolved in HCI, treated with H 2 SO 4 , and the resulting sulfates separated. Metathesis with (NH 4 )  2  C 2 0 4  resulted in conversion of the sulfates to the ammonium oxalates which were calcined at 850°C to form Ga 2 0 3  and Gd 2 0 3  of purity >99.99%.

Abstract: An improved process for the preparation of urea from carbon dioxide and excess ammonia at elevated temperature and pressure. The urea solution from the urea synthesis zone is heated and stripped at an elevated pressure to decompose a portion of the ammmonium carbamate contained therein and the ammonia and carbon dioxide containing off-gas produced is condensed in a first condensation zone. The stripped urea solution is heated at a reduced pressure in a decomposition zone to decompose a further portion of ammonium carbamate, and the ammonia and carbon dioxide containing off-gas thereby produced is condensed in a second condensation zone to form an aqueous ammonium carbamate solution. A portion of this aqueous carbamate solution is introduced into a desorption zone so as to produce an off-gas more concentrated with respect to ammonia and carbon dioxide than the ammonium carbamate solution, and the off-gas from this desorption zone is condensed into a further portion of such aqueous ammonium carbamate solution in a third condensation zone, maintained at a pressure between the pressure in the decomposition zone and about 40 bar, to form a more concentrated ammonium carbamate solution which is recycled to the urea synthesis zone.
