Title: Optical recording card and method of reading the same
Inventor: KAKINUMA YUJI
IPC: G11B7/0033
Filed: 1987-08-07
Granted: 1992-04-07
Abstract: Abstract of the Disclosure The invention relates to a scheme for correctly reading data pits with a reader even if an optical recording card is fed slantwise.   If the optical recording card is slanted relative to a line sensor for reading the card, the line sensor may ride on two or more data pit columns. However, discriminator pits are formed at the start and end of each data pit column so that the data can be processed after deciding if the optical recording card is disposed slantwise or not.   A relatively short data pit column with discriminator pits formed at the start and end thereof is used. A plurality of data pit columns are disposed with a guide bar interposed therebetween. A readout signal from the discriminator pits is used for deciding if the data pit column has been read correctly, whereas a strobe signal read from the guide bar is used for initiating a memory selector.

Title: Highly efficient calcination of gypsum to hemihydrate
Inventor: DOZSA OTTO L
IPC: B01J6/00
Filed: 1987-08-13
Granted: 1993-04-13
Abstract: Abstract of the Disclosure Hydrodynamic pumping of the fluidized calcining mass in a kettle is set up by the continuous flow of the mass to and from heating rods immersed therein which are constantly emitting at least about 1 British Thermal Unit of heat per minute per square inch of the surface of the rods.  The transfer of heat from the walls and bottom of the kettle is enhanced so that more of the available heat is actually absorbed than in a kettle lacking such heating rods.  The rate of calcination may be increased while the rate of heat input is decreased.

In the preferred embodiment, the second bracket includes an upwardly extending portion having a wedge-shaped slot and an outer arcuate bearing surface. The upwardly extending portion receives a bolt for supporting cantilevered formwork and the bolt is retained within the slot by a nut which rests against the arcuate bearing surface.  The retained bolt can be pivoted throughout a range of angular orientations relative to the second bracket at the circumstances of use may require. The first and second brackets each include a through bore for receiving additional formwork supporting bolts that are oriented substantially perpendicularly to the threaded connecting rod.

Title: Raster scan digital display system
Inventor: MOREL JEANNE E
IPC: G09G1/16
Filed: 1987-09-24
Granted: 1991-11-19
Abstract: RASTER SCAN DIGITAL DISPLAY SYSTEM                      ABSTRACT            An all  points  addressable  raster  scan  graphics display system is operable in two modes.  In the first mode, data is extracted from a refresh store, serialized, modified,  and  applied  to  a  display device at a first frequency.  In the second mode, data  is   extracted   from  the  refresh   store, serialized and partially modified  at  said  first frequency,  but  it  is  then  further modified  and passed  to  the  display  device  at  an  even  sub harmonic, for example half, of the first frequency.          The further modification includes concatenation of successive   groups   of   display   data   bits.    Accordingly, with the raster scan device operating at  a  constant  scan  velocity,  the  first  mode provides  a  high picture  element  definition  but relatively low color definition display,  and the second  mode  provides  a  display  with  an  even submultiple, for example half, the picture element definition   but   considerably   greater   color definition.

Abstract: ABSTRACT OF THE DISCLOSURE     A  method  for  separating liquids, particularly hydrocarbons from water,  whereby  a  small  amount of a high molecular weight polymer is dissolved  in the hydrocarbon to render it viscoelastic.  A hydrocarbon layer  is  then  mechanically  removed from the water in a manner which causes  rapid  stretching of the hydrocarbon with attendant development of  elastic  properties  in  the hydrocarbon layer.  The polymer may be applied  to  the surface of the hydrocarbon as droplets of a relatively concentrated  polymer  solution  or  as  solid  particulates  having  a polymer  core   covered   by   a  powdered  solid  material  which  is non-reactive toward the polymer.

Title: Fuel cell power plant reformer
Inventor: COHEN RONALD
IPC: B01J8/00
Filed: 1988-02-03
Granted: 1991-11-26
Abstract: Abstract Fuel Cell Power Plant Reformer The reformer is designed for use with a large fuel cell power plant capable of producing megawatts of power, as, for example, would be used by a public utility.  The catalyst tubes in the reformer have their upper ends at staggered elevations so as to be capable of having their temperatures individually monitored by infrared temperature sensors.  The catalyst tubes are mounted on a floating support within the reformer housing so as to be free to undergo expansion and contraction during periods of internal temperature variation as the reformer is operated.  The floating support is preferably formed from fuel manifolds suspended in the reformer housing.  Baffles are included in the reformer housing for evenly distributing heat to the catalyst tube arrays.  The reformer has a long burner tube which is approximately the same length as the catalyst tubes.

Granted: 1992-12-08
Abstract: ABSTRACT OF THE DISCLOSURE         Predetermined limits are attained for the peak loads encountered when a composite assembly of workpieces is secured with a swaged collar fastener, by disposing cavities in the cylindrical wall of the fastener collar to receive material flow during the swaging operation.  Rotation between the collar and pin of the fastener is precluded by disposing abutting portions on the pin, which interface against the swaged material of the collar. Fastener cost reductions axe achieved by decreasing the volume of a post-swage scrap portion on the pin and by concurrently fabricating grooves thereon with a rolling die, for various functional purposes. Swaging tool malfunction is avoided by eliminating land surf aces adjacent to grooves on the pin through which pull is applied thereto with the tool.
