Title: A method of forming metal matrix composite bodies by a spontaneous infiltration process and products produced therefrom
Inventor: AGHAJANIAN MICHAEL K
IPC: C22C21/00
Filed: 1989-11-06
Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum.

Title: Time variant suppression of coherent noise signals in a seismic section
Inventor: CRIDER RICHARD L
IPC: G01V1/36
Filed: 1989-12-08
Abstract: ABSTRACT         Time-invariant multichannel seismic data filters are applied to seismic data traces for rejecting coherent noise signals within a time-space window.  In one embod-iment, these filters are applied for rejecting all signals having the same trace-to-trace slopes as the coherent noise signal.  Segments of the filtered traces that are within the time-space window are added to corresponding segments of unfiltered traces outside of the time window for producing reconstituted time-variantly filtered traces.  In another embodiment, these filters are applied for rejecting the coherent noise signals and passing all other signals within the time-space window and passing all signals outside of the window for producing time-variantly filtered traces.

Inventor: WILCHER FIONA P
IPC: B01J35/10
Filed: 1990-03-23
Abstract: A novel solid phosphoric acid catalyst of controlled porosity and process for using this catalyst is disclosed.  The catalyst com-prises a combination of solid phosphoric acid and a refractory oxide binder to make a porous catalyst system having 25.0 volume percent or less of the total catalyst pore volume consisting of pores having a diameter of 10,000 Angstroms (.ANG.) or greater.  An improvement in catalyst stability is observed when such a catalyst is utilized in a hydrocarbon conversion process of the type that have traditionally used solid phos-phoric acid catalysts such as catalytic condensation of olefins to make a desired oligomer or alkylation of aromatic hydrocarbon with an olefin-acting agent.

Title: Loss of neutral or ground protection circuit
Inventor: ZYLSTRA HENRY J
IPC: H02H3/16
Filed: 1990-05-07
Abstract: ABSTRACT     A  loss  of  neutral  or  ground  protection  circuit  is disclosed which uses a simple capacitive circuit which discharges through the neutral or ground leads in normal conditions, and in the event of loss of neutral or ground charges  sufficiently to trip a circuit breaker.   The protection circuit may include other circuits such as ground fault detection circuits and may be in a one or three  phase  system.    By  virtue  of  the  fact  that  a capacitive circuit is used to trip the circuit breaker, an inherent time delay is involved and thus the circuit breaker will  not be tripped as a result of a momentary loss  of  neutral  or  ground.    This  is  particularly important where continuity of  operation of a load is important.     c:\spe\square.d3d

IPC: C01F7/02
Filed: 1990-05-08
Abstract: Abstract In order  to  avoid  the  decomposition of  the calcium  carbonate  by  the  solutions  of  acid-reacting aluminum salts used for the precipitation and fixing of the resin size in the sizing of calcium carbonate-con-taining papers with resin size dispersions, the procedure is as follows:       An  aqueous  colloidal  solution of  homogeneous aluminum hydroxide is prepared which contains 0.1 to 50 g/liter of aluminum hydroxide and has a pH of 6 to 8.          This colloidal solution is mixed with the paper pulp or the resin size dispersion under turbulent flow conditions during or immediately after its formation.       To prepare the colloidal solution,  an aqueous solution which contains  1 to 40 g/liter of an acid-reacting aluminum salt can either be mixed under tur-bulent flow conditions in a stoichiometric ratio with an aqueous solution which contains 1 to 50 g/liter of at least one alkaline-reacting substance,  or it can be passed over an anion exchanger in the OH form.

Filed: 1990-05-14
Abstract: QUICK CHANGE STRUCTURE FOR TRIM DIE     Abstract of the Disclosure A quick change apparatus for a trim die assembly is provided to reduce die set-up and change-over time.  The trim die assembly is provided with lift hooks for the forks of a forklift truck to carry it between storage and the press and to eliminate potentially damaging contact between the keyways in the bottom of the die and the forks.  Locating pins and stops are provided between the press and die assembly to permit quick and positive positioning of the die assembly above the press bed.  The connecting post between the part locator member of the trim die and the press has been modified to eliminate its projection beneath the die assembly and therefore eliminate damage to the post during set-up, movement and/or storage.  The modified post is also adapted to assist in the positioning of the die assembly on the press bed.

Title: System and method for heat recovery in a combined cycle power plant
Inventor: LEE RICHARD M
IPC: F01K23/10
Filed: 1990-05-31
Abstract: 55,160 ABSTRACT         A system and method are provided for recovering heat from the exhaust gas of a gas turbine operating in a combined cycle power plant.  Heat is recovered by transferring it to feedwater supplied to a heat recovery steam generator.  The heat recovery steam generator generates steam for expansion in a steam turbine, thereby producing additional rotating shaft power, and injection into the combustor of the gas turbine, thereby reducing nitrogen oxides in the exhaust gas.  Feedwater from the condenser is entered directly into a feedwater heater in the heat recovery steam generator, thus avoiding the use of steam for feedwater heating.  Acid corrosion is avoided by regulating the heat transferred from the exhaust gas to the feedwater heater in the event high sulfur fuel is burned in the gas turbine combustor.

Abstract: CIP of RD-19502 PREPARATION OF LINEAR POLYCARBONATES FROM             CYCLIC OLIGOMER COMPOSITIONS USING              SALICYLIC ACID SALT AS CATALYST                  Abstract Cyclic polycarbonate oligomers are converted to linear polycarbonates by the catalytic action of a monobasic metal salicylate.  The polymerization reaction takes place only at relatively high temperatures, typically above about 220°C, and rapidly only at temperatures above about 250°C, and is therefore particularly useful in such operations as resin transfer molding.  The catalyst may be coated on a fibrous reinforcing material used for composite formation.

A ground fault carrying conductor is passed through the toroid window and connects the neutral of the breaker panel to an earth ground.  A test button on the adapter housing completes a circuit for supplying current to a test winding on the toroid to simulate a ground fault condition.  The trip coil has two independent windings that are individually connected to the load contacts of the breaker such that either winding can operate the trip coil.
