Abstract: ABSTRACT A nozzle assembly for casting continuous metal strips includes a nozzle for extruding molten metal. The nozzle has a nozzle body, a nozzle inlet opening, a nozzle exit orifice and a nozzle mounting surface located proximate to the nozzle inlet.  A reservoir contains the molten metal and is in fluid communication with the nozzle.  The reservoir has a reservoir outlet opening for flowing molten metal therethrough and has a reservoir mounting surface located proximate to the reservoir outlet.  The reservoir mounting surface is adapted to mate with the nozzle mounting surface and allow a relative, sliding-type movement therebetween due to a differing thermal expansion of the nozzle relative to the reservoir.  A heat resistant seal between the nozzle mounting surface and the reservoir mounting surface minimizes molten metal leakage therebetween, and a force mechanism resiliently urges the nozzle mounting surface toward the reservoir mounting surface to mate the nozzle and reservoir together.

Abstract: ABSTRACT OF THE DISCLOSURE            A steam generator is disclosed which is provided with wall tubes (6,7) through which the working medium flows.  The tubes are supported exteriorly on girders (20) to prevent the buckling of the walls.  The girders are connected at their ends with tension bands (21) through connecting elements (10, 11, 22, 24, 25).  The bands, in turn, are secured each to that wall which is adjacent to the wall (7) supported by the respective girder.  The connection is so formed that the force transmitted from the respective tension band (21) to the girder (20) does not develop any factor in the next tension band (21).  The invention reduces the production cost of the bands and of the connecting elements.

Abstract: ABSTRACT OF THE DISCLOSURE            The oxidation of carbon fibers from pitch is carried out directly by winding the spun fiber on to a spinning spool or bobbin, said spool comprising an open ended, porous, non-expanding or collapsible spool. The spun carbon fibers are wound on such a spinning spool so as to leave open areas between fiber bundles. A mixture of an inert gas such as air or nitrogen con-taining a minor amount of oxygen is used as the oxi-dizing gas. Oxidation is carried out in a closed zone, e.g. an oven, for a period of time of at least 4 hours at a temperature that is initially below the glass transition temperature of the carbon fibers and is slowly increased over the oxidation time to a maximum of about 340°C. The gaseous oxidation atmosphere is continuously recycled and passed through the spool to ensure that the fibers are essentially completely oxidized.

Abstract: RAPID ANNEALED BORON IMPLANTED DIODES                   ABSTRACT OF THE DISCLOSURE           An improved process in making a polysilicon resistor suitable for use as a load resistor in a static  memory  wherein  after  the  doping  of  the polysilicon, the device is annealed by exposing it to a  rapid  increase  of  ambient  temperature  (up  to between 900 and 1200°C), maintaining the high ambient temperature for a controlled time (about 5 seconds) and then lowering the ambient temperature at a rapid rate.   This decreases  resistance by one order of magnitude and significantly decreases the temperature activation  energy of  the  resistor.   This permits static memory cells to retain data even though the cell  has high  leakage  currents,  thereby  improving final test yields.

Abstract: ABSTRACT OF THE DISCLOSURE     One set of circumferentially juxtaposed axial surfaces of the motor magnets of a wet motor gerotor pump are separated circumferentially by a tunnel device having a central bridge portion radially just clearing the rotating armature and bounded by a pair of leg portions extending radially outwards from the central bridge portion to establish a substantially lami-nar flow path for the fuel.  The tunnel device further spaces the armature relative to the gerotor pump cavity.  A vent valve is provided in the outlet housing of the pump.  A spring biases a ball valve against an imperfect seat encircling the inlet passage to provide a permanent vent bypass passage therebetween.  The spring seats the ball valve against the imperfect seat to permit fuel vapors to vent through the vent outlet passage until liquid reaches the ball valve.  The liquid then overcomes the bias of the spring to seat the ball against an outlet seat encircling the outlet passage to close the same.

Title: Sludge bed clarification device for solid-containing liquids
Inventor: CONDOLIOS ELIE
IPC: B01D21/00
Filed: 1985-07-31
Granted: 1989-09-05
Abstract: A cloudy liquid to be clarified is inserted, after twice receiving flocculation additive, into the bottom of a belt of sludge (4a) in a clarification chamber (4) via a plurality of injectors (22) distributed over the area of said chamber. Uniform distribution of overall flow between these injectors is ensured by internal head loss. The clarified liquid is removed via an upper overflow (4b). Each injector is constituted by a flat cyclone and forms a jet which is highly diverting from its vertical axis in such a manner that the injected flowrate spreads out over an expansion zone belonging to said injector and meeting the expansion zones of adjacent injectors. Further, these jets set up swirling motion which prevents the formation of a layer of sludge having insufficient permeability. The sludge formed in the chamber (4) is directed via a central well (7) towards a secondary clarification sludge (3) situated beneath said chamber and supplying both clarified liquid and dense sludge.

Abstract: LIQUID LEVEL SENSOR ASSEMBLY                 ABSTRACT      An oil level sensor assembly adapted for installa-tion in an automobile engine crankcase at the level corresponding to "low oil".  The sensor assembly util-izes the principle that air is expandable whereas oil is not.  Accordingly, when it is desired to sense the oil level, a predetermined amount of fluid is trapped within a chamber sealed by a diaphragm.  If the oil level is adequate, then the sensor will be below the oil level and the trapped fluid will be oil.  However, if the oil level is low, the trapped fluid will be air. After the fluid is trapped, a spring operating on the diaphragm attempts to expand the chamber.  If the admit-ted fluid is air, the chamber can be expanded and a switch contact will be made, to provide an indication of low oil level.  On the other hand, if the chamber is filled with oil, the chamber will not expand and the switch contact will not be made.
