Abstract: PCT No. PCT/US87/01462 Sec. 371 Date Feb. 22, 1988 Sec. 102(e) Date Feb. 22, 1988 PCT Filed Jun. 18, 1987 PCT Pub. No. WO88/00278 PCT Pub. Date Jan. 14, 1988.An acidizing composition and method for slowly dissolving siliceous material by the slow production of very low concentrations of hydrofluoric acid is provided by this invention. The continual generation of very low concentrations of hydrofluoric acid is accomplished by the hydrolysis of hexafluorotitanate-containing compounds. The acidizing composition is particularly useful and advantageous for the solubilization of siliceous clay in or adjacent the pores of subterranean hydrocarbon formations thereby increasing the permeability of said formations. Because of the very low concentration of hydrofluoric acid in the acidizing composition solubilization of siliceous clay deposits is possible at relatively large distances from the point of injection into the formation, for acidizing formations which are too sensitive for more reactive acidizing compositions, for acidizing formations containing chlorite clays, and/or for acidizing formations having an elevated temperature including formation temperatures of 125 DEG  C. or higher.

Title: Monitoring method for metallurgic containers
IPC: F27B3/28
Filed: 1988-07-28
Granted: 1991-09-04
Abstract: A method of detecting leaks on metallurgical vessels delivered with refractory material and equipped with cooling elements. Whereas major leaks can be detected by monitoring the flow quantities in the individual circuits of the entire cooling circuit of the furnace vessel, no method has so far been disclosed according to which even the smallest leaks, during which less than 250 cm<3> down to the quantity of a drop escapes, can be located. The method according to the invention is distinguished by the fact that cooling liquid escaping during a leak is collected as vapour and is fed to a moisture indicator and recorded. For this purpose, perforated vapour-collecting tubes (5) are installed below the cooling elements (3). A moisture indicator is attached to the outlet of each vapour-collecting tube (5) outside the furnace vessel (1). The method and device are suitable for electric-arc furnaces, reduction furnaces, etc. <IMAGE>

Abstract: Traffic jams (1) can be relieved (5) if vehicles (2) reduce their speed (3) below the currently possible value (4). For this purpose, vehicles (6) are counted during a counting interval (7) in order to derive a waiting time (8) in relation to the time (9) required by the vehicles to pass the region (10) of the potential traffic jam. The target speed (3) is obtained by dividing the waiting time (8) by the section (11) or by the driving time (12). If the actual speed (13) is greater than the target speed (3), a lower value (14) than the target speed is transferred to a speed-regulating device (15). If the actual speed is too low, a higher value is transferred. The speed is controlled at a plurality of potential traffic jam regions. The vehicles obtain equivalence values. Allowance is made for fluctuations in traffic flow at intersections. Differences in speed between sections are reduced by the process. Additional control sections are employed in peak traffic. The speed-regulating devices also influence the energy supply and the direction of motion. Vehicles are diverted if this results in shorter driving times. Aircraft obtain individual waiting time values, which they reduce in function of flight time, and are released for takeoff only if this does not cause additional major traffic jams.

Abstract: Un système d'alimentation en eau purifiée (10) comprend une unité d'osmose inverse (12) qui reçoit de l'eau (22) du robinet et produit de l'eau purifiée (26) et de l'eau de rejet (28). L'eau purifiée est ensuite acheminée dans une chambre d'eau purifiée (34) à l'intérieur d'un récipient de stockage (14), dans lequel la chambre d'eau purifiée est séparée d'une chambre d'eau de rejet (42) par une barrière mobile (41). Une ou plusieurs vannes de robinet (16) sont ouvertes pour ouvrir un circuit de décharge (70) permettant à l'eau purifiée de s'écouler ensuite par un bec de décharge (72). Un ensemble vanne de régulation (18) amène l'eau de rejet soumise à une pression suffisante jusqu'à la chambre d'eau de rejet, pour obliger l'eau purifiée provenant du récipient à traverser le circuit de décharge, et maintient un niveau de pression à l'intérieur du récipient sensiblement inférieur au niveau de pression de la conduite d'eau du robinet, afin de permettre l'utilisation d'un récipient de stockage léger et économique. Dans certains modes de réalisation, lorsque le circuit de décharge est fermé, la vanne de régulation allège sensiblement la pression à l'intérieur du récipient pour réduire au minimum la contre-pression dans l'unité d'osmose inverse.

Abstract: In a wax-moulding plant with a vacuum wax injector, the operating parameters (wax-moulding pressure, wax- moulding duration, contact pressure) are set by these operating parameters being provided on the rubber mould in the form of defined reliefs which either remain free or can be closed off by a suitable insert. A certain number of such (closed or open) reliefs form a coding field in the form of a binary number, which is sensed by the sensing members of the pressing plate of the wax-moulding plant. As a result, the predetermined operating parameters are taken over by the wax-moulding plant and the corresponding setting and controlling members are actuated. By this automatic setting, once a combination of operating parameters, and thus the wax-moulding result, has been predetermined, it can be reproduced with high accuracy. In addition, more than one person can work on a wax-moulding plant, which increases productivity.
