Title: Arrangement for switching concentrated telecommunications packet traffic
Inventor: HEMMADY JAYANT G
IPC: H04L12/56
Filed: 1988-11-22
Granted: 1993-03-30
Abstract: ARRANGEMENT FOR SWITCHING CONCENTRATED TELECOMMUNICATIONS PACKET TRAFFIC                  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. The data switching modules each use a synchronous data ring for transporting data packets between data link handlersand a plurality of memory access controllers and their associated memory modules.

Granted: 1992-09-22
Abstract: TITLE: MASS SPECTROMETER AND METHOD WITH IMPROVED        ION TRANSMISSION                   ABSTRACT OF THE DISCLOSURE            In  a  mass  spectrometer  system,  ions  travel through an orifice in an inlet plate into a first vacuum chamber  containing  AC-only  rods,  and  then  through  an orifice into a second vacuum chamber containing a stan-dard quadrupole.   The second vacuum chamber is held at low pressure, e.g. .02 millitorr or less, but the product of the pressure in the first chamber times the length of the AC-only rods is held above 2.25 X 10-2 torr cm, pre-ferably between 6 X 10-2 and 15 X 10-2 torr cm, and the DC voltage between the inlet plate and the AC-only rods is kept  low,  e.g.  between  1  and 30  volts,  preferably between 5 and 10 volts.  This produces a large enhance-ment  in ion signal, with less focussing aberration and better sensitivity at high masses,  and also allows the use of smaller, cheaper pumps so the system can be more easily transportable.

Granted: 1993-01-12
Abstract: ABSTRACT OF THE INVENTION            Method and means for drawing a convex geometric figure to framebuffer storage sequentially addressable as a plurality of update arrays of determined origins which tile the framebuffer.  An array comprises pixel storage sites, each specifiable by an offset from array origin.  The sites are concurrently updatable.  A figure is specified as a set of directed lines; the line segments between mutual intersections comprise the figure boundary; the segments perambulate the boundary in a single sense.           For an update array, concurrently for each pixel site, and concurrently for each directed line, the sidedness of the pixel is evaluated with respect to the line to derive a one-bit line discriminant signal.  For each site, the line discriminant signals are ANDed to derive a result discriminant signal; a first value specifying outsidedness of the pixel with respect to the figure prevents writing to the site. The process is repeated for further arrays to tile the figure to be drawn.

Abstract: Abstract A process is described for producing an aluminum grain refiner, such as Al-Ti-B grain refiner.  Molten aluminum is continuously flowed as a bottom layer along a substan-tially horizontal or slightly inclined trough.  Titanium or boron compounds reducible by aluminum  or a mixture of such compounds is added to the surface of the aluminum layer such that a discrete separate layer of these is formed on top of the aluminum layer.  Reaction between the aluminum and the titanium and/or boron compounds occurs along the interface between the layers and this reaction may, if desired, be aided by providing relative movement between the layer of molten aluminum and the layer of titanium and/or boron compounds.  A surface layer of spent reaction product is removed and a stream of aluminum alloyed with titanium and boron is collected.

Abstract: The invention relates to a corrosion protection element comprising a laminate consisting of two spaced high-purity zinc foils, a layer or an elastic adhesive sealing material between said foils, and a coat of a permanently elastic adhesive on the side of one of said zinc foils facing away from the elastic adhesive sealing material layer, said latter adhesive coat being covered by a strippable adhesive-protecting liner.  After the liner has been withdrawn, the corrosion protection element may be applied by placing it with its self-adhesive coating down on the surface of one of two parts in the area where they are to be connected.  Because of its permanent deformability, it will provide an optimum seal at the juncture between the parts as they are being connected; at the same time, it provides long-term protection from corrosion as the high-purity zinc foils of the laminate provide cathodic anticorrosive action.  Relative movements of the connected parts will in no way impair the sealing and anticorrosive effects the inventive corrosion protection elements affords.

Abstract: ABSTRACT     A device for controlling a cursor on a data terminal display screen.  The device is in the form of a headset and includes an orientation sensor which provides an electrical signal related to the orientation of the device without it being adjacent to any fixed surface.  The orientation sensor includes a hollow spherical housing having at least one light source/detector pair mounted opposingly in the inner wall, along an axis extending through the center point of the housing.  The housing is half-filled with a transparent liquid having a specified viscosity and index of refraction and half-filled with air.  Light beams emitted from the sources are refracted upon passing through the boundary between the air and the liquid.  As the orientation sensor rotates with respect to the vertical axis, the changing refraction angle of the light beam causes the detector to sense changing intensities of light, which are representative of the angle of rotation. Multiple light source/detector pairs spaced within the spherical housing allow measurement of direction and magnitude of angular change.  Integral with the input device is a speaker independent voice control circuit which recognizes short isolated command words ending in voiced or fricative sounds for controlling display functions.
