IPC: G01R27/18
Filed: 1988-05-11
Abstract: The device consists of a circuit 14 for injecting an alternating reference signal and an electronic detection circuit 16 having means for discrimination of the components of a measuring signal proportional to the insulation impedance Z formed by a leakage resistance Rf in parallel with a stray capacitance C. A synchronous detector 30 has a pair of static inverters 32, 34 for processing the first component depending on the current IR passing through the leakage resistance Rf and the second component depending on the current IC flowing in the capacitance C. A convertor 36 combines with the generator 20 to deliver two signals C1 and C2 in quadrature for controlling the inverters 32, 34 respectively. A display unit 58 gives an accurate indication of the value of the leakage resistance Rf.

Abstract: Selon les procédés connus, la poussière déposée sur la surface extérieure des éléments de filtrage (2) est enlevée par des impulsions de gaz sous pression appliquées à l'intérieur des éléments de filtrage (2) et qui sont declénchées uniquement lorsqu'une pression différentielle est mesurée à travers les éléments de filtrage. Selon ces procédés, les impulsion de nettoyage sont declénchées de manière précoce et inutile dans certains circonstances, lors de changements du débit volumique. Afin de faire dépendre le nettoyage de la quantité réelle de poussière déposée, on détermine le débit volumique pour chaque conteneur (1), outre la pression différentielle à travers les élements de filtrage, et l'impulsion de nottyage est déclenchée lorsque le rapport croissant dans le temps lors de la formation d'une couche de poussière entre la pression différentielle et le débit volumique atteint au moins une valeur limite inférieure (S1) déterminée par des essais. Ce procédé convient en particulier au dépoussiérage de gaz de fumée dégagés par des couches fluidisées de combustion sous pression ou atmosphérique.

Abstract: Une tablette sans eau forme, lorsqu'elle est mâchée dans la bouche, une pâte auto-moussante contenant du fluorure stanneux. Ladite tablette contient moins de 50% environ en poids d'une composition produisant du bioxyde de carbone lorsqu'elle est mélangée avec la salive dans la bouche et plus de 35% environ en poids d'une composition de charge et de polissage sensiblement insoluble ainsi qu'une composition d'humectage et de stabilisation de la mousse qui forme la pâte. La composition de charge et de polissage comprend de préférence plus de 50% environ de ladite tablette et ladite composition produisant du bioxyde de carbone comprend moins de 25% environ en poids de ladite tablette. Ladite tablette ne contient pas d'eau afin d'empêcher la dégradation du fluorure stanneux avant l'utilisation. On mâche une telle tablette pour former la pâte. On fait circuler la pâte dans la bouche et entre les dents, afin d'obtenir une action de nettoyage mécanique et pour placer le fluorure stanneux en contact avec la surface des dents. La tablette est ensuite avalée. En utilisant une telle tablette deux fois par jour, on obtient un effet anti-carie et anti-plaque supérieur à ce qui est obtenu avec n'importe quel produit d'hygiène dentaire existant.

Abstract: A process and arrangement 
are provided for the efficient genera­
tion of energy from coal, while at the 
same time providing for a relatively 
inexpensive step in processing of ir­
on or steel, and the extraction of val­
uable materials such as oils from 
coal. An advantage to the process is 
that relatively low quality coals can 
be utilized, since the coal is pretreat­
ed before any burning operation. 
Generally, the process involves three 
interacting stages. In the first stage, a 
coal liquefaction/pyrolysis proce­
dure is utilized to drive off volatiles, 
and form a very low volatile char. 
The volatiles can be collected and ut­
ilized as a valuable oil product, such as for diesel fuel or the like. The char material is preferably pelletized and utilized as 
a reductant, in a second stage of iron reduction and melting. Preferably the iron reduction and melting operation is con­
ducted in a pressurized cupola and the high pressure hot product gases are utilized directly and/or indirectly, to generate 
electricity in stage three, and to produce hot steam for use in drivig certain portions of stages one and two. High pressure 
product gases have a greater energy content than gases at atmospheric pressure and facilitate more efficient production of 
electricity in stage three. Problems of handling molten iron from a pressurized cupola are solved using the pressure to 
drive the molten iron up a vertical tap mechanism. The weight of the metal offsets the pressure as the metal rises so that the 
metal is driven up to a point at which the metal's pressure is decreased to atmospheric pressure. Also, preferably steel is 
formed from the reduced iron product of stage two. Preferred arrangements for generating steel are shown.

Abstract: An expert system wherein the rules are of three classes: 1) 
retrieval rules (210), which each associate one of several attri­
butes to an object in accordance with the values of inputs; 2) an­
alysis rules (220), which selectively associate an attribute with an 
object, and which are somewhat analogous to the natural-lan­
guage inference rules which would be used in communications 
between domain experts; and 3) action rules (230), which selec­
tively carry out the output and control actuation options, based 
on the attributes associated with objects by the other rules. This 
system permits certain rules to be revised at any time without re­
quiring the specialized skills of a 'knowledge engineer'. The ex­
pert system can be used in conjunction with an integrated system 
for process control (150), which itself can exist as a separate, dis­
crete entity. This integrated system for process control contains a 
process supervisor procedure (130) (which is preferably the top-­
level procedure) which can define parameters for one or more 
controller systems (or control procedures). The supervisor proce­
dure can also be configured as a modular software structure with 
modules which can be revised by a user at any time, without sign­
ificantly interrupting the operation of the process supervisor. Us­
ers can define or redefine modules by editing highly constrained 
templates (115,812).

Abstract: Disclosed are novel thermoplastic polyurethanes capable of being produced in a range of physical properties. The novel feature resides in the combination of a minor amount of a polyol with a particular difunctional isocyanate reactive compound having a molecular weight of from 350 to 550 and itself being present in minor proportions, in reaction with an organic polyisocyanate and a conventional extender. 
     One of the advantageous features is that polymer properties can be altered particularly to higher modulus values without requiring an increase in conventional extender concentration. This means that the expensive isocyanate component need not be increased in order to toughen the plastic.

Abstract: The invention is related to a method of cooling a hot synthesis gas containing solids under conditions which permit removal of solids from solid gas. The hot synthesis gas is passing at initial high temperature downwardly through a first contacting zone, thereby passing a film of cooling liquid on walls of said first contacting zone that is cooling said synthesis gas; the so cooled synthesis gas is passing a body of aqueous cooling liquid in a second contacting zone; the further cooled synthesis gas containing a decreased content of solid particles is withdrawn upwardly from said second contacting zone through a annular third contacting zone to a vapor-liquid desengagement zone with an arcuated path terminating the gas stream with a substantial downward component of velocity whereby the non-gaseous components contained therein are downwardly directed toward said body of aqueous cooled liquid thereby forming a synthesis gas stream of lower solids content; 
said synthesis gas stream of lower solids content is passing again upwardly. Said cooled synthesis gas will be recovered.

Abstract: In an ink jet printer, a print head (1) comprises a front nozzle member (2) having a front channel (3), a housing (4) secured to the front nozzle member, and a rear nozzle member (7) which defines with the housing a liquid chamber (5) and further defines with the front nozzle member a laminar airflow chamber (10a). The rear nozzle member has a forwardly projecting nozzle (8) and a rear channel (9) extending from the liquid chamber through the projecting nozzle in axial alignment with the front channel (3) to form a meniscus at the front end. The airflow chamber is connected to an air supply for directing air to a point between the front and rear channels (3, 9) so that it creates a sharp pressure gradient along a path therebetween. A dead air region is created in a location adjacent the exit end of the rear channel to cause the meniscus to take a dome-like shape which is stabilized against vibrations and transients. An electric field gradient is established between the front channel and the meniscus to cause the latter to extend toward the front channel and expelled through the front channel. A portion (2a) of the front nozzle member is liquid-repellant to prevent the field distribution from being seriously disturbed by an ink layer formed on it by stray ink particles.

Abstract: A transient flow capillary viscometer is provided for establishing a measure of the viscosity of a highly viscous test fluid. More particularly, a capillary tube (12) filled with test the fluid is provided. The viscometer relies upon inducing a step change in the differential pressure across the ends of the capillary tube, which causes the fluid to flow therein. The resultant decrease in pressure drop as a function of time, i.e., the half-life of pressure decay, is monitored and provides an approximate measure of the viscosity of the fluid.
