Abstract: ABSTRACT           Apparatus for exchanging a pouring tube in communication with the outlet valve of a metallurgical vessel includes a pivot arm which is mounted to pivot about a vertical axis and a hori-zontal axis.  One end of the pivot arm carries a mounting for supporting the pouring tube and the other end cooperates with a toggle lever mechanism.  A pivotally mounted actuating lever is positioned to contact the toggle lever mechanism to exert a force on a spring assembly carried by the pivot arm and thus to exert a torque on the pivot arm about the horizontal axis.

Abstract: ABSTRACT              METHOD OF COATING METALLIC SURFACES      Metallic surfaces, especially of ferrous metals, are coated by passing an electric current at a voltage of at least 15V between the metallic surface as anode and a cathode in contact with a composition comprising (A) an epoxide resin, and (B) a salt of formula   where Ay+ denotes a cation which is a metal, a metal complex an organometallic, a heterocycle, a sulphoxonium, ammonium, a substituted ammonium or a phosphonium ion, y denotes 1, 2, or 3, Z-denotes an anion selected from perchlorate, trifluoromethane sulphonate pentafluorohydroxoantimonate, and the complex anions of formula MQd-, M represents a boron, phosphorus, antimony or arsenic atom Q represents a halogen atom, and d is 4 or 6 and is one more than the valency of M, whereby polymerised epoxide resin is deposited on the metallic surface.      Typical salts (B) include sodium, potassium, magnesium, ammonium, substituted phosphonium and substituted ammonium trifluoromethane sulphonates, perchlorates, tetrafluoroborates, hexafluorophosphates, hexafluoroarsenates, and hexafluoroantimonates.      This process gives a very rapid coating on the metallic surface without the need for special formulations to render the epoxide resins electrodepositable.

Abstract: SYSTEM FOR SPRAY COATING SUBSTRATES A system for spray coating a substrate such as a plastic container with a gas barrier coating of a polymer dispersion. The system includes a spray coating booth or chamber including spray nozzles dispensing a spray of a coating material onto the surface of a series of containers continuously moving into and out of the coating chamber, an oven for drying the wet coating to remove the water from the coating to form a dried film on the container without distorting the container, and a conveyor for transferring the containers into the coating booth into proximity to the spray nozzles such that on actuation of the nozzles a stream of coating material coats the surface of the bottles with a wet coating layer and, thereafter, to the oven where the wet coating is dried. Means are provided for rotating the bottles during coating, during transport between the spray coating booth and the oven, and while in the oven. The coating booth includes a system for containing and removing both airborne and liquid overspray from the booth, and a dual delivery system for delivering the coating material to the spray nozzles and for reverse flushing the delivery system. The system operates to provide a continuously moving series of containers with a spray coating at production rates suitable for commercial applications.

Abstract: ABSTRACT      Water is separated from an oil emulsion containing a surface active agent by passing the emulsion through a polymeric porous membrane cross-flow ultra-filter.  Either the oil emulsion feedstock or the membrane is treated with a hydrophilic colloid so that the effective pore size of the composite membrane so formed by the colloid will be reduced as the surface tension falls in the presence of the surface active agent in the oil emulsion.  The hydrophilic colloid is selected according to the chemical ionic classification of the surface active agent.

A set of configuration parameters is defined for both an asynchronous and telephonic  communication function set.  Additionally, a set of interrupt conditions is defined for both the asynchronous and telephonic communication function sets.  These parameters and interrupt conditions control the interaction of the software applications across the interface with the system hardware.  Means are provided for directing commands coming from a software application across the interface to the system hardware.  Likewise, means are provided for generating interrupts and handling these interrupts from the system hardware across the inter-face back to an interrupt routine within the software application.

Inventor: BUEHLER FRITZ
IPC: E01B31/17
Filed: 1987-01-22
Granted: 1990-05-01
Abstract: ABSTRACT     By means of several measuring sensors , the distances            from several generatrices of the rail-head profile to a reference base are measured and are compared as actual values with pre-determined desired distance values.  The grinding heads, which are set to a specific generatrix and which grind a facet at an angle of inclination corresponding to the position of each generatrix, are always lifted off auto-matically when this facet reaches the position corres-ponding to the desired distance value in relation to the reference base.  Because the distance to a particular generatrix, on which is located the vertex line of two adjacent facets of a pair of facets, is measured as an actual value, any two adjacent facets can be checked simultaneously by means of one and the same measuring sensor           .  The two facets of a pair of facets are ground by means of a double grinding head set to the vertex line and having two grinding wheels, the grinding planes of which form a predetermined working angle (.alpha.) with one another which corresponds to the desired pro-file.  The control of the grinding heads therefore mere-ly involves a simple comparison between desired values and actual values of distances; furthermore, double the number of facets can be checked by means of a specific number of measuring-sensors, and consequently the rail profile can be approximated as closely as possible.

Abstract: ABSTRACT OF THE DISCLOSURE         A power interface circuit includes a low voltage control chip and a separate, high voltage power chip contained in a common package.  The high voltage power chip includes a power switching semiconductor de-vice, such as a thyristor or power MOSFET, and is con-trolled under the influence of the control chip.  Oper-ating power for the low voltage control chip is pro-vided from an auxiliary portion of the high voltage power chip.  Such auxiliary portion comprises a voltage regulator, which derives its power from a high voltage lead in the power device.  The high voltage lead may comprise a lead on which high voltage power is supplied for power switching purposes.  The low voltage control chip may include a high degree of "intelligence", or logic functions, for controlling the power switching device, since the low voltage device may be a micropro-cessor or other device that can be fabricated with a high density of control elements.
