Patent EP-0160377-A1 (EP)
Inventor: GHOSH CHUNI LAL
IPC: H01L31/10
Filed: 1985-03-19
Abstract: 57 A semiconductor device is fabricated on a substrate by initially forming a layer (2) of n-type InGaAs on one major surface of the substrate (1), followed by formation of either a layer or a gate (3) of p-type InGaAs, p-type InP or n-type InP on such n-type InGaAs layer, application of gate metallisation (4) to the layer or gate, removal of the material surrounding the gate, and formation of source and drain contacts (6 and 7) on the n-type InGaAs layer at mutually opposite sides of the gate. The semiconductor device can be used as a photodetector for light penetrating through the other major surface of the substrate toward the gate region.

Abstract: The water level in a boiler 9 is monitored by a probe 15 driven by an AC source 11. If the water is high, the water resistance Rw completes a first current path i1 which charges C1 via D1 on alternate half-cycles and alternately charges and discharges C2 on successive half-cycles. C1 then transfers its charge through R2 to C3 via path i2, which has a long time constant (20 sl. When C3 is charged, amplifier A1 energizes relay RL1, which closes contacts RL1/1, so modifying the characteristics of current loop i2, and closes contacts RL1/2, closing fuel valve 44 and allowing boiler 9 to be heated. If the water level falls, charging of C1 via loop i1 ceases: charging of C3 via the loop i2 (which now has R2 shunted out) ceases; and C2 discharges through D2 and R4 via loop i3. When the voltage on C3 falls enough, amplifier A1 output changes, de-energizing relay RL1, so opening contacts RL1/2 and turning off the boiler flame, and also opening contacts RL1/1 and so re-establishing the original characteristics of C3 charging current loop i2.

Abstract: A gate valve includes a frame (23) to which are secured inlet and outlet body portions (21, 22) with annular valve seats (49, 50) thereon. A gate assembly (24) is movable between open and closed positions, within the frame and between said body portions, and carries first and second pairs of sealing rings (42, 43; 45, 46) in opposite faces thereof. The first pair (42, 43) is adapted to be brought into sealing relationship with said valve seats when the valve is open, whilst the second pair is adapted to be brought into sealing relationship with the valve seats when the valve is closed. The body portions (21, 22) have a plurality of bolts (56) passing therethrough which are adapted to threadably engage the sealing rings to uniformly draw the rings toward their respec­tive valve seats to clamp a gasket structure (51, 52) between a ring and its seat in positive seating relat­ionship. The bolts are adapted to be withdrawn from the rings to permit the gate assembly to be moved between open and closed positions. The bolts (56) have washers (62) associated therewith which engage the gasket structure (51, 52) when the bolts are withdrawn from the sealing rings, to move the gasket structure out of contact with the gate assembly to prevent abrasion of the gasket structure when the gate assembly is moved.

Abstract: Un matériau en fusion, en particulier des métaux, peut être transformé directement en fibres en laissant un courant de matériau en fusion s'écouler en travers d'une rampe (12), formant ainsi une fine couche (20) de matériau en fusion sans appliquer une pression hydrostatique. A une extrémité de sortie de la rampe, une roue (24) portant une pluralité d'arêtes passe au travers de la couche mince (20) de matériau en fusion, tirant ainsi une pluralité de filaments. L'appareil élimine le problème de la formation de bandes rencontré dans les appareils de l'art antérieur qui utilisent une pluralité d'arêtes à espacement serré.

Abstract: An apparatus for distributing charge material to a shaft furnace is presented which effectively reduces the segregation of the particles in a storage housing positioned above the shaft furnace. In the present invention, the storage hopper and the distribution device are movable about the vertical axis of the shaft furnace and are mounted inside a sealed chamber. Above the chamber are arranged at least two locks which are each provided with upper and lower sealing flaps. Preferably, the storage hopper and the bottom of each of the locks are in the configuration of tapered funnels, the conical wall of which forms an angle of less than or equal to about 30 DEG  with respect to the vertical axis of the furnace. The storage hopper is preferably supported by support and guide rollers which move on a circular rail integral with the wall of the sealed chamber and is subjected to the action of a drive mechanism for rotation about the vertical axis of the furnace. Anti-segregation boxes are preferably provided both in the locks and in the hopper, to ensure better filling and guarantee a more uniform distribution of the particles of differing granulometry.

Abstract: A fluid catalytic cracking unit equipped with multiple feed injection points along the length of the riser is operated such that portions of the same fresh feed are charged to different feed injection points. Preferably, the hydrocarbon fresh feed can be split into two or more non-distinct fractions, with one fraction charged to the bottom injection point along the length of the riser reactor, and the remaining fractions charged to injection points progressively higher up along the length of the riser reactor. Unconverted slurry oil boiling above 650°F can be recycled to one or more of the various injection points along the length of the riser. Steam in excess of levels typically employed for dispersion is used at the bottom of the riser to help lift the regenerated catalyst. Other inert gases can be used in place of, or in conjunction with, steam to accomplish lifting of the catalyst in the riser.
