Abstract: Disclosed is a multiplexing method and apparatus that allows holograms to be spatially multiplexed with partial spatial overlap between neighboring stacks of holograms. Each individual stack can additionally take full advantage of an alternate multiplexing scheme such as angle, wavelength, phase code, peristrophic, or fractal multiplexing, for example. An amount equal to the beam waist of the signal beam writing a hologram separates individual stacks of holograms. Upon reconstruction, a hologram and its neighbors will all be readout simultaneously. An filter is placed at the beam waist of the reconstructed data such that the neighbors that are read out are not transmitted to the camera plane. Alternatively, these unwanted reconstructions can be filtered out with an angular filter at an intermediate plane in the optical system that has a limited angular passband.

Abstract: A method for monitoring diffraction while reading a hologram includes: illuminating a holographic medium with a reference beam to generate a data beam for a hologram that has been recorded at a set diffraction efficiency with a first polarization, the reference beam having a second polarization; and measuring an offset component in an output arm of the data beam.

Abstract: A process for the isolation and purification of (RR,SS)-2-?(dimethylamino)methyl!-1-(3-methoxyphenyl)cyclohexanol and its salts from a Grignard reaction mixture which includes the (RR,SS) isomer, the (RS,SR) isomer and Grignard reaction side products. An aqueous solution of HBr is added to the reaction mixture to effect the selective precipitation of the (RR,SS) hydrobromide isomer from the mixture while the (RS,SR) isomer remains in solution. The precipitated (RR,SS)-2-?(dimethylamino)methyl!-1-(3-methoxyphenyl)cyclohexanol hydrobromide is converted to (RR,SS)-2-?(dimethylamino)methyl!-1-(3-methoxyphenyl)cyclohexanol hydrochloride.

Abstract: A lock guard (10) for use with a padlock (200) and a conventional tractor trailer door latch system (100). The lock guard (10) comprises a main housing unit (11) dimensioned to cover the door latch system (100) and including an exterior auxiliary housing unit (13) provided with a cut-out (61) dimensioned to receive a padlock (200) and an interior center piece unit (13) having an aperture (42) dimensioned to receive a portion of the padlock for captively engaging portions of the trailer door latch system.

Abstract: An apparatus for releasably clamping a substrate to a support platform, or other support means, at a face of the substrate is described. In one embodiment, a retractable clamp holds a substrate near its edges on a support platform when the clamp is in its fully extended position. One or more leaf springs are mounted to the clamp and apply force to the substrate at respective points in the event the substrate adheres to the clamp, thereby releasing the substrate from the clamp. In a preferred embodiment of the present invention, one or more activators are positioned in cooperative relationship to the leaf springs to cause the leaf springs to retract into recesses in the clamp when the clamp is extended against the substrate. In their retracted position, the leaf springs do not contact the substrate so as to minimize the generation of particle contamination and the chance of the release leaf springs themselves adhering to the substrate.

Abstract: A method for the rapid cooling of a raw egg in a shell, the shell egg being warm and having an internal temperature typically of about room temperature or higher. The method preferably involves placing the shell egg for about 1 to about 5 minutes in an atmosphere of cryogenic gas at a temperature of about -60.degree. F. (about -51.degree. C.) to about -120.degree. F. (about -84.degree. C.), whereby the internal temperature decreases sufficiently to inhibit residual pathogenic and/or spoilage microorganisms, such as Salmonella and/or Pseudomonas, respectively, present inside the shell egg. Also a cool raw shell egg in a shell that has been rapidly cooled in an atmosphere of cryogenic gas after having been warmed, typically to where the shell egg had an internal temperature typically of about room temperature or higher. The cool shell egg that has been so subjected to rapid cooling has fewer viable residual pathogenic and spoilage microorganisms, i.e.

Abstract: A modular lighting system is described comprising a plurality of elongated light modules which are selectively connected in an end-to-end relationship to achieve the desired light length. Each of the light modules have a female plug portion on one end thereof and a male plug portion on the other end thereof. The desired number of light modules may be secured together in an end-to-end relationship by inserting the male plug portion of one light module into the female plug portion of an adjacent light module. The light modules are provided with a plurality of light bulbs mounted thereon and a reflector positioned at one side thereof.

Abstract: An externally applied urinary collection and diverting device for incontinent females; including a substantially closed housing having an opening for an ingress conduit with a flexible cup-like diaphragm to fit over the urethral opening to direct urine to the interior of the housing which has a further opening along the length thereof to direct the urine to a collection receptacle without leakage along the vulva area; the housing is of such relatively small size as to be substantially self supporting by entrapment by at least partial covering thereof by the labial folds when positioned for use, and the housing may have attached thereto a perineal pad for similar entrapment thereof in the fourchette area for further support; and with ambulatory females, the housing is shaped to removably and adjustably receive a vaginal insert for still further stabilization and support of the device.

Abstract: A method of forming membrane covered laminate strips of a desired predetermined length from an elongated porous strip wherein said strip is impregnated at spaced predetermined sections with a fluid seal material to preclude fluid flow through such sections and is also coated on each face with a suitable membrane forming coating material to thereby form a laminate strip suitable for reverse osmosis and/or ultrafiltration usage. The resulting laminate strip is provided with a punched hole in a portion of the impregnated section to effect a fluid passageway opening therethrough and, additionally, is cut transversely through an intermediate portion of such section to result in the formation of a multiplicity of predetermined length laminate strips. A plurality of stacked strips, with the punched hole positions staggered in adjacent strips, or groups of strips, provides a simplified form of apparatus with an elongated serpentine flow path therethrough for separating the constituents of a fluid feed stream.
