Title: Distributed control rapid connection circuit switch
Inventor: RICHARDS GAYLORD W
IPC: H04L12/00
Filed: 1988-11-23
Granted: 1993-03-30
Abstract: DISTRIBUTED CONTROL RAPID CONNECTION CIRCUIT SWITCH Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user. Distributed control of the space division switch is implemented by dividing that switch into disjoint sets of connection and switching elements and controlling each such set with a differentcontroller. These controllers communicate via a separate control network with the data switching modules which request circuit connections.

Title: System for output plane calibration of an optical correlator
Inventor: LEIB KENNETH G
IPC: G06V10/88
Filed: 1989-05-24
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE A system for calibrating the output correlation plane of an optical correlator for positional and nonlinearity information to determine the position of an input image in an input image plane of the optical correlator. The optical correlator operates on the principle of projecting the Fourier transform of an input image onto at least one matched filter having recorded thereon the Fourier transform hologram of an image of interest. The inverse Fourier transform of the correlated optical signal is then projected onto a detector to determine the correlation of the input image with the image of interest. A calibration image is positioned in the input image plane of the optical correlator, and includes a two dimensional array of substantially identical targets, with the precise location of each identical target in the input image plane being known. At least one matched filter is placed in the optical correlator, and has recorded thereon the Fourier transform hologram of the identical target. The positions of the resultant optical signals in the output correlation plane are then correlated with the position of the two dimensional array of identical targets in the input image plane to calibrate the output correlation plane of the optical correlator for positional information and nonlinearity. The calibration system of the present invention enables an optical correlator system to be precisely calibrated in a way that the system can continue to operate using the same optical computing array. The calibration system can be used with any prescribed input format, e.g. 35mm, 70mm, 5", etc.

Abstract: ABSTRACT            An arrangement in shelf, tray, drawer structures (10) or like structures of the kind which can be moved between an inserted position, for the storage of articles, e.g. packages such as drugstore packages, and a position of use in which the packages can be removed from the trays or the like. The trays or the like are mounted on brack-ets (12) which are fitted to a frame structure (22) in a manner to enable the brackets to be adjusted between mutually different positions, and optionally to be removed from the frame structure.            The trays, drawers or the like include catch means (36) which are intended to latch the trays or the like in a fully inserted position in the brackets (12). The brack-ets (12) can be adjusted on the frame structures (22) such as to extend horizontally or at an inclined angle. The trays or drawers and/or the brackets are configured so that when the brackets (12) are in their horizontal positions the trays or drawers cannot be inserted to their full extent, thereby preventing the catch means (36) from coming into operation. This can be achieved, for instance, by inclining the end wall surface of respective trays, such that the end wall will slope obliquely outwards and upwards from the bottom of res-pective trays. When the brackets (12) are adjusted to their inclined positions, the trays or the like (10) can be fully inserted and thus latched by the catch means (36).

Granted: 2011-05-24
Abstract: Disclosed are a family of synthetic proteins having binding affinity for a preselected antigen, and multifunctional proteins having such affinity. The proteins are characterized by one or more sequences of amino acids constituting a region which behaves as a biosynthetic antibody binding site (BABS). The sites comprise V H-V L or V L-V H-like single chains wherein the V H and V L-like sequences are attached by a polypeptide linker, or individual V H or V L-like domains. The binding domains comprise linked CDR and FR regions, which may be derived from separate immunoglobulins. The proteins may also include other polypeptide sequences which function, e.g., as an enzyme, toxin, binding site, or site for attachment to an immobilization media or radioactive atom. Methods are disclosed for producing the proteins, for designing BABS having any specificity that can be elicited by in vivo generation of antibody, for producing analogs thereof, and for producing multifunctional synthetic proteins which are self-targeted by virtue of their binding site region.

Abstract: A pipe of thermoplastic polymer, e.g. polyvinylchloride is extruded.The wall thickness of the pipe is controlled in order to obtain a pipe of a substantially even wall thickness. For said control the wall thickness of the extruded pipe is measured at 360 points equally distributed over the circumference and moreover the average is determined in eight measuring sectors comprising 45 measuring points per sector. The average of the measuring values of one measuring sector is compared with the circumferential average of the 360 points, the deviation of the desired wall thickness in said one sector being counter balanced by the action of the heating elements.The apparatus of the invention for executing the method of extrusion of a pipe of thermoplastic polymer comprises an extruder with an extrusion die 2 having a moulding end part 2a and heating elements 11, 11' located about said end part 2a, and a wall thickness measuring device 7 being rotatably about the circumference of the pipe. The wall thickness measuring device 7 is transmitting measurement data to a signal processing unit 9. A comparator element 10 is provided for comparing two values of measurement values averaging operations and said comparator element 10 acts upon the temperature control device 8 controlling the temperature of the heating element 11 in a temperature control sector located in the axial extension of a measuring sector as compared with the average of the total circumference of the pipe.
