Title: Fuel cell thermal control and reforming of  process gas hydrocarbons
Inventor: BAKER BERNARD S
IPC: H01M8/0612
Filed: 1979-12-04
Granted: 1983-04-05
Abstract: Abstract Thermal control and fuel processing in fuel cell opera-tion is effected through sensible heat of process gas and hydro-carbon reforming by supplying process gas in common to a flow pas-sage in communication with the cell electrolyte and an additional gas flow passage which is isolated from the cell electrolyte and includes catalyst promoting endothermic reforming of hydrocarbon content of the process gas.  Flow level in the electrolyte-communication flow passage is selected based on desired output electrical energy and flow level in the additional gas flow pas-sage is selected in accordance with desired cell operating tempera-ture and desired extent of fuel processing.

Title: Parallel ring and ring extension support  system for dynamoelectric machines
Inventor: FIDEI FRANK P
IPC: H02K3/50
Filed: 1980-01-25
Granted: 1982-09-07
Abstract: 16                       46,870 ABSTRACT OF THE DISCLOSURE A dynamoelectric machine having a casing struc-ture which includes a thin cylindrical member, circumfer-entially separated axial gussets attached to the cylindri-cal member's interior, at least two axial rows of arcuate structural segments connected between the axial gussets, a cylindrical stator core, and a stator winding distributed on the stator core and having phase terminals.  Conductor rings and ring extensions protruding therefrom are sup ported within the casing structure at one axial end there-of by  conductor  ring  clamp  systems  and ring extension clamp structures respectively.   Circumferential posi-tions of the ring extensions correspond to the circumfer-ential  positions  of  the phase  terminals.   Phase  leads which  electrically  connect  the phase terminals and the ring  extensions  have  standard  lengths.   The number of phase lead standard lengths equal the number of different radial distances the phase terminals are displaced from the  stator  core's  axis.   Attaching  the  conductor ring clamping systems to the arcuate structural segments per-mits clamping system disposition at the circumferential positions corresponding to the ring extensions' positions. The ring extension clamp structures connect to the conduc-tor ring clamp systems and provide optimum rigidity to the ring extensions.   The conductor ring clamp systems each include two blocks which each have indentations in one edge.  The indentations on one block are juxtaposable with the indentations on the other block so as to cooperatively provide openings  for the reception and retention of the 17                  46,870 conductor rings.  The ring extension clamp struc-tures are similarly configured, but usually have only one indenta-tion in each block for receiving and retaining the ring extension.

Abstract: (U.S. 974,070 etc.) ABSTRACT OF THE DISCLOSURE         A continuous solvent dewaxing process wherein a waxy oil is prediluted with a non-autorefrigerative solvent, such as ketone and then passed, at a temperature above its cloud point   to the top of a chilling zone (fig. l (26)), which is an autorefrigerant chilling zone operating on a continuous basis, and comprises a vertical, multi-staged tower, operating at constant pressure.  In this chilling zone, wax is precipitated from the oil to form a waxy slurry and the so-formed slurry is further chilled down to the wax filtration temperature by stage-wise contact with liquid propylene which is injected into a plurality of said stages and evaporated therein so as to cool the waxy slurry at an average rate  of between about 0.1 to 20°F. per minute with an average temperature drop across each stage of between about 2 and 20°F.  Some of the propylene remains in the oil which serves to further dilute and reduce the viscosity of the slurry. The dewaxed oil-containing slurry may then be fed directly to wax filters without having to pass through scraped-surface chillers and filter feed drum.          In a preferred embodiment the non-autorefrigerant solvent is employed cold so as to partially solvent dewax the waxy oil to a temperature within from about 30 to 110°F. of the final wax filtration temperature before being contacted with autorefrigerant in the auto-refrigerant chilling zone to be chilled down to the desired wax filtration temperature.

Abstract: UNIDIRECTIONAL FORCE GENERATOR                      ABSTRACT          A device (8) for producing a unidirectional force may be used to propel a vehicle (10) or other body in one direction or to serve in other applications requiring such a force,  The device uses at least one centrifugal force generator (20, 22, 24, 26) which repetitively provides al-ternately occurring prolonged centrifugal forces of opposite direction along a line fixed relative to the generator,  As these forces are produced the generator is turned relative to a supporting carriage (12) so that each time such a force occurs it has a generally forward direction relative to the carriage.  Two or more centrifugal force generators may be mounted on a single carriage and operated in synchronism and in proper phase relationship to one another to produce a forwardly directed force of relatively steady magnitude and/or to cancel force components directed perpendicular to the forward direction.

Abstract: Abstract of the Disclosure Garbage to be converted is fed into the upper end of a vertical chamber.  A gas collection chamber is provided around the upper end of the chamber and a blower is used for lowering the pressure in this gas collection chamber.  The lower pressure causes a draw within a combustion zone defined at the lower end of the garbage chamber.  This draw promotes combustion of garbage in the combustion zone much in the same manner that the draw by a pipe smoker will promote combustion within the bowl of his pipe.  The gas collected in the gas chamber is delivered through a water filled cleaner or filter.  The gas discharged from the upper end of the filter is ready for use in a power device or a furnace, or it may be collected and compressed or even liquified, into a storage container, for easy mobility and later use.

Abstract: METHODS AND APPARATUS FOR FEEDING AND HANDLING ELECTRICAL PHASE INSULATORS    FOR DYNAMOELECTRIC MACHINES   ABSTRACT OF THE DISCLOSURE           Methods are disclosed of intermittently advancing a chain of insulators to a severing and transfer mechanism loading station while guiding end turn insulating portions along guide means while applying a frictional restraining force to the insulators.  After the transfer mechanism is loaded with a leading insulator from the chain; the leading insulator is severed from the chain, the transfer mechanism is conditioned to receive the next leading insulator from the chain, and the loading and severing sequence is repeated.  The loaded insulators are then wrapped about the transfer mechanism by spinning the mechanism and insulators and deflecting portions of the insulators projecting from the mechanism into close proximity to the mechanism.  The wrapped insulators are then moved along the bore of a stator, released, unwrapped, and transferred to the stator.  Apparatus disclosed herein includes material supply means, guide means, adjustable for differently sized insulators; insulator advancing and severing means; insulator transfer means, including an arbor and end insulator retainers; arbor spinning means; insulator wrapping means; arbor moving means; and arbor actuating means for positively transferring insulators from the arbor to a stator.

Abstract: A COMPATIBLE  AM STEREO BROADCAST SYSTEM                               ABSTRACT      A compatible AM stereo broadcast system has a pair of carriers in quadrature are separately modulated with stereo information.  The resulting signal is multiplied by the cosine of an angle 0, the angle between the vector sum of the two carriers and a line that bisects the angle between the carriers in quadrature.  The signal envelope contains the sum of the information on the two channels, thus providing compatible monophonic reception.  In a stereo receiver the two carriers in quadrature can be restored by dividing the signal by the cosine of the angle 0.  The original modulation can be obtained from each channel by product detection.
