Title: Pressure vessel closure device
Inventor: FRUCHTBAUM JOSEPH
IPC: F27D1/18
Filed: 1993-04-13
Abstract: Abstract of the Disclosure There  is  disclosed  a  flange  or  pressure  vessel closure device and method for deheading a coke drum.  The coke  drum  deheading  device  has  an  annular  retaining element spring biased from a lower flange of a coke drum, and a plurality of hooks which extend from the retaining element  to  engage  a  cradle  holding  the bottom  head against the flange.  When it is desired to disengage the head from the flange, the hook retaining element is moved by a first set of cylinders toward the flange to release tension from the hooks so that they can be disengaged from the bottom head by pivoting them outwardly using a second set of cylinders or other hook pivoting means. The bottom head can then be disengaged from the flange, lowered and moved laterally away from the coke drum on a hydraulic table.

Title: Cover fabric with latex foam backing and integrally foamed article using the same
Inventor: OGAWA TARO
IPC: B32B5/20
Filed: 1991-08-27
Abstract: A B S T R A C T     A composite cover material to be used for making an inte-grally formed article comprises a permeable fabric (10) and a thin layer of latex foam (15) strongly bonded via bondding zone (17) to said fabric. The latex foam layer (15) is made by applying high molecular latex material such as rubbers or synthetic resins as coating to back surface (12) of said fab-ric, and permitting said latex material to foam and cure. The latex foam has relatively fine mechanical open cells (18) in its internal part and further fine open cells (20) near its outer surface skin (22) which is permeable by virtue of minute holes (21) formed therein.  The skin (22), though permeable by minute holes,  can serve as substantially flat and smooth bar-rier surface agaist liquid foamable mixtures poured directly onto said skin for making body foam (25) so as to guide slid-ingly said mixtures therealong and also prevent substantial impregnation into said latex foam.

Patent CA-2098626-A1 (CA)
Title: Apparatus for discharge surface liquid
Inventor: YAMAMOTO HIDEO
IPC: E02B15/04
Filed: 1993-06-17
Abstract: A base fixed to a Liquid-containing tank and a float disposed above the base are liquid-tightly secured to lower and upper ends, respectively, of a flexible member comprising a bellows cylinder. The base, the float and the flexible member define a liquid reservoir.      The float rises when there is a large quantity of liquid in the reservoir and falls when there is a small quantity of liquid in the reservoir, so that a damming plate provided on the float is moved above and below the surface of the liquid in the tank. When the damming plate is moved below the liquid surface, the liquid on the surface flows into the reservoir through a liquid inlet formed in the float, and the liquid that collects in the reservoir is discharged to the exterior of the tank by a liquid discharge pipe. As the float rises, the damming plate is lifted above the surface of the liquid in the tank, thereby cutting off the flow of surface liquid into the reservoir. This operation is performed repeatedly to remove the surface liquid from the tank.

Title: Pupil-tuned multifocal ophthalmic lens
Inventor: ROFFMAN JEFFREY H
IPC: G02B3/10
Filed: 1993-12-07
Abstract: An ophthalmic lens provides a cumulative ratio of distance to near focal length that is predominantly distance correction under high illumination, nearly evenly divided under moderate illumination, and favoring again distance vision correction under low level illumination. The lens is specifically adjusted to match the patient's pupil size as a function of illumination level, in the preferred embodiment by applying pupil size parameters as a function of age. This lens has the properties of matching both the distribution of near and distance focal vision correction to the type of human activity typically undertaken in various illumination conditions, as well as matching particular lens dimensions to suit the size of the pupil as a function of illumination intensity.

Title: Multiple access coding for radio communications
Inventor: DENT PAUL W
IPC: H04J13/00
Filed: 1993-04-08
Abstract: Individual information signals encoded with a common block error-correction code are assigned a unique scrambling mask, or signature sequence, taken from a set of scrambling masks having selected correlation properties. The set of scrambling masks is selected such that the correlation between the modulo-2 sum of two masks with any codeword in the block code is a constant magnitude, independent of the mask set and the individual masks being compared. In one embodiment, when any two masks are summed using modulo-2 arithmetic, the Walsh transformation of that sum results in a maximally flat Walsh spectrum. For cellular radio telephone systems using subtractive CDMA demodulation techniques, a two-tier ciphering system ensures security at the cellular system level by using a pseudorandomly generated code key to select one of the scrambling masks common to all of the mobile stations in a particular cell. Also, privacy at the individual mobile subscriber level is ensured by using a pseudorandomly generated ciphering key to encipher individual information signals before the scrambling operation.
