Title: Reforming of fuel inside fuel cell generator
Inventor: GRIMBLE RALPH E
IPC: H01M8/06
Filed: 1987-07-09
Granted: 1991-04-09
Abstract: ABSTRACT OF THE  DISCLOSURE Disclosed is an improved method of reforming a gaseous reformable fuel within a solid oxide fuel cell generator, wherein the solid oxide fuel cell generator has a plurality of individual fuel cells in a refractory container, the fuel cells generating a partially spent fuel stream and a partially spent oxidant stream.  The partially spent fuel stream is divided into two streams, spent fuel stream I and spent fuel stream II.  Spent fuel stream I is burned with the partially spent oxidant stream inside the refractory container to produce an exhaust stream.   The exhaust stream is divided into two streams, exhaust stream I and exhaust stream II, and exhaust stream I is vented. Exhaust stream II is mixed with spent fuel stream II to form a recycle stream.  The recycle stream is mixed with the gaseous reformable fuel within the refractory container to form a fuel stream which is supplied to the fuel cells.           Also disclosed is an improved apparatus which permits the reforming of a reformable gaseous fuel within such a solid oxide fuel cell generator.  The apparatus comprises a mixing chamber within the refractory container, means for diverting a portion of the partially spent fuel stream to the mixing chamber, means for diverting a portion of exhaust gas to the mixing chamber where it is mixed with the portion of the partially spent fuel stream to form a recycle stream, means for injecting the reformable gaseous fuel into the recycle stream, and means for circulating the recycle stream back to the fuel cells.

Title: Forms of transition metal dichalcogenides
Inventor: MORRISON S ROY
IPC: C01G35/00
Filed: 1987-09-08
Granted: 1991-04-09
Abstract: NEW FORMS OF TRANSITION METAL DICHALCOGENIDES   ABSTRACT Novel single layer materials of the form MX2, where MX2 is a layer-type dichalcogenide such as MoS2, TaS2, WS2, or the like, exfoliated by intercalation of an alkali metal, and immersion in water, are disclosed.  MoS2 has been exfoliated into monolayers by intercalation with lithium followed by reaction with water.  X-ray diffraction analysis demon-strates that the exfoliated MoS2 in suspension is in the form of one-molecule-thick sheets.  X-ray patterns from dried and re-stacked films of exfoliated MoS2 indicate that the layers are randomly stacked.  By adsorbing monolayers or precipitating clusters of vari-ous species such as compounds of Co, Ni, Pb, Cd, Al, Ce, In and Zn, on MoS2 while the sulfide is suspended as single layers and then recrystallizing, a new group of inclusion compounds can be formed.  In the re-crystal-lized or re-stacked materials, the inter-layer spacing can be expanded or contracted compared to MoS2.

IPC: B65H39/115
Filed: 1987-10-08
Granted: 1993-10-19
Abstract: Abstract A collating station for a machine intended to insert first and second documents into an envelope.  Prior to the insertion operation, the first and second documents are advanced serially in a common plane.  At a predetermined location, each first document is intercepted and lifted above the common plane and, in a positive fashion, moved to a holding platform spaced above the common plane.  The holding platform has a transverse terminal edge downstream from where the first document comes to rest.  Thereupon, the first document resting on the holding platform and a following second document which continues to advance along the common plane as the first document travels toward the holding platform  are advanced together, now in a parallel spaced relationship, toward a downstream station.  As the first and second documents are advanced, the first document drops off the terminal edge of the holding platform and onto the  second document  thereby completing the collating operation.  The operation insures that information presented on the face of the first document desirably remains visible throughout the operation and upon  the completion of the operation.  Additionally, movement of the first document is positively controlled as it is guided to locations above the common plane, thereby assuring proper collation of the first and second documents.   The desired sequence of events performed by the various components can be achieved by means of a variable computer control,  or by a fixed timing sequence built into the machine,  or by sensors and associated activating devices, or by a combination of these expedients.

Granted: 1992-03-10
Abstract: Abstract A method for efficient generation of compiled code is presented in accordance with the preferred embodiment of the present invention.  In order to gain significant performance advantage with a minimum of code expansion, out-of-line code sequences are used.  An out-of-line code sequence is a series of instructions that are invoked by a simplified calling mechanism in which almost no state-saving is required.          Additionally, out-of-line code sequences is designed so that a single copy can exist on a system and all processes running on that system can access it.  A series of out-of-line code sequences can be generated, each member of the series being tailored to a particular combination of compile-time information.

Title: I-q channel adaptive line enhancer
Inventor: BULLOCK SCOTT R
IPC: H03H21/00
Filed: 1988-03-25
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE      An I-Q channel adaptive line enhancer has bandpass filters with passbands that can be widened to well beyond the band that is actually being processed by the adaptive line enhancer.  This eliminates the requirement of filtering one of the sidebands as is required in  single channel adaptive line enhancers, in which the sum and difference sidebands are generated on up-conversion.          Band limiting is done with lowpass filters, and the local oscillator may be made variable so that any part of the band that is passed by the bandpass filters can be processed by a single I-Q channel adaptive line enhancer.  This type of I-Q channel adaptive line enhance can process any one of a large number of possible banks without tunable bandpass filters, or without banks of adaptive line enhancers which have been preset to adjacent sub-bands.

Abstract: ABSTRACT          A method of deploying a cable or other line in a fluid transportation pipeline whilst in normal operation full of and transporting a fluid under a positive pressure.  A collapsible centralising device is attached to the loading end of the cable and is then fed in a collapsed state into the pipeline via a first fluid scaling means at the cable entry position.  That device maintains the cable end centralised in the pipeline cross section whilst the cable is fed into the pipeline. Magnetic sensing means disposed near the cable exit position sense the presence of the cable end and control the cable infeed so as to position the cable end in a predetermined cable retrieval position. A tubular lance is fed into the pipeline through a second fluid scaling means disposed at the cable exit position, and a grab housed in the nozzle of the lance is ejected to engage and capture part of the centralising device and cable end, whereafter the grab closes on being drawn back into the lance.  The lance is then withdrawn through the second fluid scaling means so as to draw with it the grab and the captured centralising device and cable end.            Refers:  Figure 2.

A group reply signal is sent back to the inter-rogation unit from any transponder having, in the field being interrogated, a bit matching that required by the interrogation signal.  The interrogation unit is arranged to determine, from the series of received reply signals, the identity of each and every valid transponder within range.
