Title: Electromagnetic contactor with control circuit for providing acceleration, coast and grab functions
Inventor: BAUER JAMES A
IPC: H01H50/34
Filed: 1988-02-05
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE An electromagnetic  contactor or  controller  is taught in which the voltage which is impressed across the electromagnetic armature accelerating coil is compared by a microprocess against a menu of memory stored voltages with related delay angles.  The delay angles are utilized to alter the conduction interval of a triac or similar gated device which is connected in series circuit relationship with the coil in question.  During an ACCELERATION interval a number of consecutive full-wave rectified half-cycles of voltage pulses are phase angle or delay angle controlled so that the amount of energy provided to the moving armature of the contactor is approximately sufficient to cause the armature to  abut  a  fixed magnetic member.   Furthermore, there is provided a separate memory menu for mid-flight adjustment  of  the  armature  to  compensate  for  unknown variations to fine tune the closing operation.  This latter correction is known as COAST.  There is also provided a GRAB function which supplies limited, relatively low level current to the armature at or near the time of abutment for preventing "bounce".  Mechanically interconnected with the armature is a set of contacts which are caused to close upon an external circuit for providing a useful function in response to the movement of the armature.

Abstract: ABSTRACT     Disclosed is a method of optimizing the structure of an electromagnet so that when its coil is energized by electrical pulses of predetermined duration and amplitude the electromagnet induces voltages of first and second predetermined magnitudes in a standardized search coil located midway between pole faces of the iron core at times corresponding to the beginning and end of the pulses.  The voltage induced in the search coil at the beginning of the pulses is measured and, if it is greater than the first predetermined magnitude, the number of turns of the coil is increased whereas, if it is less than the first  predetermined magnitude, the number of turns is decreased.  The voltage induced in the search coil at the end of the pulses is also measured and, if it is greater than the second predetermined magnitude, the gauge size of the wire forming the coil is reduced whereas, if it is less than the second predetermined magnitude, the gauge size is increased.  Also, the coil current flowing  at the end of the pulses is calculated and the point of intersection of the current with a saturation curve of the iron core is checked; if necessary, the cross-sectional area of the iron core is altered to ensure that the point of intersection is near the upper limit of the linear region of the saturation curve.

Abstract: COMPOSITE MATERIAL CENTRIFUGE ROTOR                ABSTRACT OF THE DISCLOSURE         A composite material centrifuge rotor and process of construction of the rotor is disclosed.  A rotor having high stiffness of fibers, preferably carbon, bound together with resin is disclosed.  The rotor in-cludes a top disk, a bottom disk and a spacer belt spac-ing the two disks apart to form a rotor assembly.  The top and bottom disks are fabricated by overlying multi-ple layers of tape, the tape being made from longitudi-nally extending and parallel fibers held together with resin.  The tapes are stacked in multiple layers normal to the spin axis of the rotor so as to lie within the plane of the centrifugal force exerted by the rotor. Successive layers of tape are oriented so as to vary the longitudinal direction of the fiber with respect to a preselected radius vector from the spin axis of the rotor.  When the tape is compiled in multiple layers to a thickness of the top and bottom disk, the tape is compressed between two metal plates and cured at a tem-perature well above the expected autoclave temperature of sterilization of the rotor.  Thereafter, a spacer belt consisting of a spirally wound resin impregnated and cured fiber is placed to space the top and bottom disks apart.  Thereafter, the entire assembly is wound by a peripheral belt with resin impregnated high stiff-ness fiber.  This fiber is cured and shrinks during curing to exert hoop tension around the periphery of the rotor assembly.  This hoop tension in turn radially prestresses the rotor equal and opposite to the radial tension forces of centrifugal force when the rotor is in use.     Beckman 8D-507

Abstract: RECYCLE OF OILY REFINERY WASTES                        ABSTRACT     Petroleum refinery waste stream sludges are recycled by segregating the sludges according to their oil content.  Sludges of high oil content are injected into a delayed coking unit during the coking phase so that they are converted to coke and liquid coking products. High water content sludges are used to quench the coke during the quench phase of the coking cycle, with minimal increases in coke volatile matter.  The process increases the capacity of the delayed coking unit to process and recycle refinery waste sludges and produce a coke of lower volatile content.

Title: Method for making composite articles that include complex internal geometry
Inventor: PYZIK ALEKSANDER J
IPC: C22C1/10
Filed: 1989-04-24
Granted: 1993-07-06
Abstract: ABSTRACT     A process is described for making a composite article without shrinkage, particularly of ceramic and metal wherein the article includes complex internal surfaces or cavities.  The process requires forming an insert body that includes an external surface that corresponds to an internal cavity of the article.  The insert body consists of a material having a melting temperature less than that of the article.  The process further requires forming a porous compact about the insert body wherein the compact is formed into the substantially the net shape of the article.  The compact is made of a material that is wetted by liquid insert material and has a sintering temperature greater than the wetting temperature of the insert material. The process further requires heating the article to a temperature such that the inserts substantially melts and infiltrates the porous compact forming the finished composite article.  The process produces products 36,764-F     including complex internal surfaces without the necessity of costly and sometimes technically difficult internal machining operations.     36,764-F

Abstract: ABSTRACT OF THE DISCLOSURE   In a computer system having a hierarchical file structure, a file system is provided which permits users of the system to share a file hierarchy and also have a private hierarchy in which files are automatically copied to as they are modified. Through the system of the present invention, a directory appears to the user as a single directory but may actually comprise files originating from a number of directories which are connected to one another through search links. Each directory has a search link associated with it which contains the path name of the back layer or directory behind it. The first layerseen through the system of the present invention is the front layer, private to the user. The back layers behind the front layer and connected to the front layer through the search links are shared layers accessible to multiple users. Thus transparent to the user the directory accessible comprises multiple layers comprising shared and private files. The system further provides a copy-on-writefeature which protects the integrity of the shared files by automatically copying a shared file into the users private layer when the user attempts to modify a shared file in a back layer.   82225.P051
