Title: Method for determining compositional information of a multilayer web
Inventor: LIPPERT JOSEPH L
IPC: G01N21/35
Filed: 1992-12-08
Abstract: A METHOD FOR DETERMINING COMPOSITIONAL INFORMATION OF A MULTILAYER WEB               Abstract of the Disclosure A method for obtaining quantitative compositional information from a multilayer web containing a highly light-scattering component.  The compositional information is obtained by measuring and analyzing the transmitted or diffusely reflected infrared spectrum. The method allows for separately determining the moisture content of hydrophobic (non-hydrogen bonding) layers and hydrophilic (hydrogen bonding) layers of multilayer webs. The separate measurements of moisture content can be made simultaneously in moving webs having both types of layers present.  The method is used to determine further compositional information such as the thickness of the individual support and gelatin containing layers, plasticizer content, retained solvents content, and the presence of other components in webs, especially photographic webs.

Abstract: ABSTRACT The invention relates to a method for monitoring and controlling the data flow in a packet data net or a datagram net comprising lines and nodes, the lines via nodes connecting by the network comprised terminals between which traffic takes place in the form of data packets or datagram. Every line and every node comprises a process preceded by a certain queue of data packets/datagram. Data packets are sent in to the net from the terminal for with a given frequency during a given time interval. If during this interval no throttling order is received from the following process, the frequency is increased by a given factor. This occurs successively until a given maximum frequency is reached. If on the other hand a throttling order is received during the interval, the frequency is instead reduced by  a  given  factor which also  occurs successively until no throttling order is received during an interval.

Title: Memory write protection method and apparatus
Inventor: RAGO FRANCESCO
IPC: G11C7/24
Filed: 1992-08-03
Abstract: A write protection apparatus is disclosed. The write protection apparatus couples a data supplying device (121) to the data input of a memory device (127). The memory protection device generates a first signal (211) which triggers generation of a second signal (215). The second signal (215) is active for a first predetermined time and is coupled to the input of the memory device (127).  At any time during this first predetermined time, a third signal (209) may be generated. The third signal (209) inactivates the second signal. This third signal (209) may be triggered by numerous events including: generation of a read signal, generation of a chip select signal, or indication that the end of the data to be written to the memory device (127) has occurred.

Title: Detection of soluble alloantigen immune complexes
Inventor: POULETTY PHILIPPE J
IPC: G01N33/569
Filed: 1992-10-30
Abstract: Reactivity between alloantigen and alloantigen-specific ligand, such as HLA and anti-HLA antibody, is detectable in a sample by separating from the sample a portion of a targeted class of ligands (including such ligands complexed with alloantigen) and measuring the amount of alloantigen in such complex containing fractions.  In another embodiment of the invention, reactivity between a plurality of samples is detected by measuring soluble alloantigen in at least first and second biological samples and in a mixture of the samples. Since the formation of alloantigen immune-complexes in the mixture alters the physical and immunological behavior of soluble alloantigen, a divergence between the measured and expected concentration of the mixture indicates reactivity.

Title: Method and apparatus for detecting cataractogenesis
Inventor: THURSTON GEORGE M
IPC: A61B3/13
Filed: 1992-01-02
Abstract: A method and an apparatus are disclosed for using quasielastic light scattering to determine the degree of cataractogenesis of a lens in vivo. By collecting and analyzing light scattered from the lens, it is possible, using the temporal autocorrelation function, to produce a signature of cataractogenesis, accounting for scattering due to immobile scatterers. The components of the cataractogenesis can also be detected by comparing the values of the components of the signature of cataractogenesis to frequency distribution of the components taken from populations or by detecting changes in the values of the components of the signature of cataractogenesis as a function of time.

Filed: 1993-12-14
Abstract: Tubeless printhead-priming cap (12) and system (10) for ink jet printers are described. The system (10) is preferably implemented, using the existing printer carriage (18) drive motor, by the use of a printhead-sealing cap (12) having a rolling diaphragm in a lower region thereof that defines a chamber (20) within the priming cap (12), with the diaphragm being reciprocated, by a spring-returned lever (26) having a piston (22) on one end thereof, in synchronism with lateral and differential vertical movement of a cap-carrying sled (14). Priming is performed uni-directionally to avoid reverse priming of the printhead (16). The chamber (20) may be emptied by reversing the operation of the priming cap (12) to pump accumulated ink into a blotter (36) by positioning the priming cap (12) against an ink blotter (36) provided in a rotatable member (30) defining a multi-service station.

Filed: 1992-07-17
Abstract: A new type of holographic recording in photorefractive crystals is disclosed, termed orthogonal data storage, in which counterpropagating, reflection mode holograms are wavelength multiplexed to form gratings lying along a common axis. It is shown that this configuration provides substantial improvements in data storage capacity in comparison to prior art systems and that higher coupling coefficients are achieved. In consequence, not only storage of data but a wide range of other devices including wavelength selective filters, lenses and optical correlation systems are disclosed. Further, methods of writing and processing metastable images are disclosed which substantially improve the strength of the gratings that are permanently developed in the medium. These methods include advantageous use of electrical potentials and photovoltaic properties, together with different interrelationships during processing.

Title: Ball cap peaking and display device
Inventor: JACOBS NEIL
IPC: A42B1/00
Filed: 1994-10-12
Abstract: A peaking and display device for increasing the curvature of the brims of sports caps and visors comprises a hollow shell adapted to lie on a table or to be mounted to a wall, and a number of preferably arcuate slots,  although possibly defining an acute angle at their respective apex, defined in the shell. Each slot is adapted to receive therein a portion of the brim of a ball cap with the span of the free ends of the slot being such that side edges of the brim located  in  the  slot  are  disposed  more  closely together  than  in  the  original,  i.e.  manufactured, position thereof. The curvature radius of each slot is smaller than that of the original brim and is such that the slot plastically deforms the brim, whereby once  removed from the  device  the brim defines  at least temporarily a curvature having a radius less than  that  of  the  original  brim.  The  device  can include a series  of  slots  having different  and/or identical radii for displaying one or more caps and for possibly imparting different shapes or degrees of deformation to the brims of the caps.  A number of identical devices can be detachably connected side-by-side.
