Inventor: VOGT HANS-GUENTER
IPC: C08F236/12
Filed: 1997-02-25
Abstract: Latices based on conjugated dienes are produced using emulsion polymerisation by introducing the monomers to be polymerised into the initially introduced seed latex in the presence of a free-radical forming activator and an emulsifier in such a manner that the ratio of the monomer polymerisation rate to the monomer feed rate is less than 0.7:1 and by performing polymerisation up to a monomer conversion of >= 95% at temperatures of 10 to 85°C, wherein the addition of the emulsifier is controlled in such a manner that the final particle size (TG L) of the latex to be produced is governed by the following equation:        TG L = TG S × (m L/D L)1/3/(m S/D S)1/3, in which D L =  density of the latex particles in the latex to be produced D S =  density of the particles of the seed used m L =  mass of the latex particles in the latex to be produced m S =  mass of the particles of the seed used TG L = particle size of the latex to be produced TG S = particle size of the seed used.

IPC: H01H47/32
Filed: 1996-07-22
Abstract: Electronic drive circuitry for a solenoid that utilizes a pulse width modulation scheme is disclosed. The solenoid is connected in series with a transistor and a sense resistor. The voltage across the sense resistor is compared to a reference value to determine if an over-current condition exists within the solenoid. The circuitry operates on a repetitive time window scheme in which current is allowed to flow through the solenoid at the beginning of each time window, regardless of whether an over-current condition exists. If an over-current condition was detected at any time during the time window, then the current will be shut off to the solenoid during the next time window after the initial portion of that window. Conversely, if no over-current condition was detected during a time window, current will be allowed to flow during the entire duration of the next time window. Wraparound circuitry is also provided for sensing an open-coil condition during a latter portion of one of the time windows after a plurality of such windows has elapsed.

Title: Connectivity matrix-based multi-cost routing
Inventor: SEID HOWARD A
IPC: H04L12/56
Filed: 1997-07-02
Abstract: Connectivity matrix-based multi-cost routing includes defining a generally additive operator which is able to add traditionally (arithmetic) additive cost factors and which takes into account cost factors which are not additive, the generally additive operator being defined such that distributive and communicative properties are applicable, and wherein the generally additive operator is applicable to connectivity matrix-based factors for determining the relative costs of paths within a network, particularly with respect to multi-cost factors.      Connectivity matrix-based multi-cost routing is performed by first defining cost functions and establishing a criteria for prioritizing cost functions such that a composite multi-cost function includes the cost functions in the priority order defined by the criterion. A connectivity matrix is established including ordered n-tuples of cost factors corresponding to the priority established by the criterion, and a shortest path matrix determination is made by using the generally additive operator to apply the composite multi-cost function to the connectivity matrix. When links within a network support various functionality, a mask of a required functionality may be used to define a cost function for a given shortest path matrix determination. A correcting method is provided for a routing determination when, after a shortest path matrix determination, a routing choice is not provided which would otherwise satisfy a multi-cost requirement, the correcting method including the determination of a primary path and secondary paths between a source node and a destination node.

Title: Purified stat proteins and methods of purifying thereof
Inventor: VINKEMEIER UWE
IPC: C12Q1/68
Filed: 1997-10-15
Abstract: The present invention describes methods of producing milligram quantities of three forms of puriried Statl protein from recombinant DNA constructs. In addition, the Stat proteins may be isolated in their phosphorylated or nonphosphorylated forms (Tyr 701). The proteins can be produced in baculovirus infected insect cells, or E. coli. A compact domain in the amino terminus  of Stat .alpha. was isolated and found to enhance DNA binding due to its abiliry to interact with a neighboring Stat protein. A relatively protease-resistant recombinant truncated form of the Stat protein was isolated in 40-50 mg quantities. Purification of the Stat proteins were performed after modifying specific cysteine residues of the Stat proteins to prevent aggregation. Activated EGF-receptor partially purified from membranes by immunoprecipitation was shown to be capable of in virro catalysis of the phosphorylation of the tyrosine residue of Statl known to be phosphorylated in vivo. Techniques are enclosed to separate the phosphorylated from the nonphosphorylated Stat proteins. The techniques disclosed are general for Stat proteins and may be used to isolate large quantities of purified Stat 2, 3, 4, 5A, 5B and 6. Methods for using purified Stat proteins, truncated Stat proteins, or Stat N-terminal fragments for drug discovery are also disclosed.
