Title: High Pressure Valve for Railway Car Brake Control Valve Device
Inventor: HART JAMES E
IPC: B60T15/42
Filed: 1993-10-27
Abstract: A spool type valve arrangement in which a booster spring is employed to overcome static friction of the spool valve O-rings and thereby assure prompt actuation of the spool valve member.   The arrangement is such that the booster spring is only active through a limited distance of travel from release position toward application position, this limited distance of spool valve travel being selected so  as  to  occur prior  to  any  transition  of  the  port connections controlled by the spool valve.  In this manner, the spool valve return spring force need not be increased in order to reset the spool valve sufficiently to re-establish the original spool valve port connections.

Abstract: A tubular recuperative heat exchanger structure is mounted in a housing chamber within a fuel-fired condensing furnace in the vertical flow path of supply air being flowed through the housing by a blower.  The heat exchanger structure comprises a primary heat exchanger defined by a vertically serpentined series of combustor tubes into open inlet ends of which a series of inshot-type fuel burners flow flames and hot combustion gases, and a secondary heat exchanger formed from a horizontally extending series of finned heat exchanger tubes having inlets in flow communication with the outlets of the combustor tubes and outlets in flow communication with the inlet of a draft inducer fan.  The firing rate of the furnace is correlated to the configuration and relative geometries of the primary and secondary heat exchanger tubes in a manner making the overall heat exchanger highly compact and thermally efficient in addition to reducing air blower and draft inducer electrical consumption as well as reducing the operating noise of the furnace.

If the incoming reference signal is interrupted or lost the circuit is switched to a holdover mode where the input of the primary loop is switched to the stable scaled output of the secondary loop. In holdover mode, the output, of the primary loop is phase-locked to the stable output of the secondary loop. When the reference clock signal is reestablished, the input of the primary loop is switched back to the reference clock signal.

Abstract: In the case of a process for manufacturing a window (glazing) made of laminated glass including one or more wires (4) which are arranged within a thermoplastic interlayer and are electrically connected to busbars (3), the wires (4) are heated by application of suitable energy, limited locally, at the connection points, before electrical connection to the busbars (3), in such a way that the surface layers (4A) adhering to the surface of the wires are thereby removed. Suitable energy, limited locally, is applied by means of laser radiation, by moving the focus (5) of a beam of laser radiation, oriented perpendicularly to the busbars (3), in the longitudinal direction (arrow F) of the busbars (3) along the latter. Next, the wires (4) are soldered to the busbars (3). The layers forming the laminated-glass windows are then assembled in the usual way and joined together hot and under pressure. <IMAGE>

IPC: A62D101/28
Filed: 1995-06-06
Abstract: A method, especially applicable on a continuous basis to commercial process streams, for treating unwanted by-products and/or impurities contained  in those streams. The method comprises the reaction in situ of such by-products or impurities with a reagent, preferably selected for its reactivity under ambient conditions of the process stream, to produce one or more materials which may then be separated from the process by economical means. The treated stream may be recycled to the process for further processing. While the method is not limited as to the process to which it is applied nor to the reagent or reagents used, in one convenient embodiment, formaldehyde in aqueous solution is reacted with an alkali metal sulfite or bisulfite to produce the corresponding salt, which may then be separated essentially completely by, e.g., distillation or membrane separation, etc., or its concentration  in the process may be controlled by, e.g., continuous removal of a purge stream, etc.

Title: Particle agglomeration and precipitation from a gaseous stream
Inventor: DULLIEN FRANCIS A L
IPC: B01D45/08
Filed: 1996-01-31
Abstract: The performance of a precipitator for separating liquid or solid particles suspended in a gaseous stream is improved when the particles are fine or ultra-fine, e.g. submicron, by treating the stream before it enters the precipitator to agglomerate the fine particles into larger ones.  This result is achieved by passing the stream successively through a series of screens.  Some particles entrained in the stream impact on solid portions of each screen, and become agglomerated in the process.  Subsequently, a large portion of the agglomerated particles are re-entrained in the stream and pass to the precipitator.  Since only a small percentage of the particles impacts each screen, a relatively large number of screens is normally preferred, e.g. at least 30.  An improved form of precipitator employs pleated sheets to form the surfaces on which the particles are collected.
