Title: Low molecular weight, water-soluble copolymers, process for their preparation, and detergent compositions comprising such copolymers
Inventor: HUGHES KATHLEEN ANNE
IPC: C09K23/52
Filed: 1990-07-31
Granted: 1993-12-23
Abstract: This invention is concerned with copolymers containing, as copolymerized monomer units, units of aliphatic monoethylenically unsaturated dicarboxylic acid such as maleic acid, and units of at least one comonomer selected from monoethylenically unsaturated monocarboxylic acids, such as acrylic acid, and carboxyl-free monoethylenically unsaturated monomers, such as alkyl esters of acrylic acid. This invention is particularly concerned with the use of low levels of copper ions in an aqueous emulsion polymerization process to promote copolymerization of the above-mentioned monomers at high conversion while maintaining and improving molecular weight control. The copolymers are useful primarily as antiscalants, dispersants, hard surface cleaners, detergent builders and incrustation inhibitors.

Title: High level production of bovine growth hormone
Inventor: MYERS-KEITH PAULA
IPC: C12N15/18
Filed: 1986-07-14
Granted: 1990-09-06
Abstract: A high density fermentation process for high yield production of a protein having bovine growth hormone activity by transformant E. coli strains is described. The process employs transformant strains of E. coli containing a gene coding for a protein having bovine growth hormone activity under the control of a bacteriophage lambda promoter-operator and a gene coding for the λc1857 temperature-sensitive repressor protein. In the initial growth period, the level of dissolved oxygen in the fermentation medium is maintained at about 20% to 60% saturation and the temperature of the medium is maitained at a temperature at which the λc1857 repressor protein is active. Production of the desired protein is then induced by raising the temperature of the medium to at least about 42°C. The temperature is then reduced to about 38°C to 41 °C to optimize cell growth for the remainder of the induction period, during which the level of dissolved oxygen in the medium is maintained at about 10% to 40% saturation, and the protein having bovine growth hormone activity thus produced is recovered from the transformant cells.

Title: Echo compensation by adaptive transversal filtering
Inventor: PFEIL DIRSKO VON
IPC: H04B3/23
Filed: 1987-01-29
Granted: 1988-06-30
Abstract: In a trunk circuit for digital signals, a digital subtracting circuit (3a) and an adaptive transversal filter (7) are inserted in a shunt branch between the transmitting path (6) and the receiving path (19). On the trunk circuit (6,19), digital signals are transmitted in the original frequency band from 0.3 to 3.4 kHz. A direct voltage or a digital sweep or noise signal in the original frequency bands 0 to 0.3 and 3.4 to 4 kHz, which are generated in the digital additional-signal generator (15a), are superimposed on such a received signal via a digital adding circuit (11a). This prevents the coefficients from escaping from a predetermined band. When analog/digital and digital/analog converters are inserted for digital operation of the adaptive transversal filter (7), connection to analog trunk circuits is also possible. These echo compensators are used, in particular, in international gateway exchanges. <IMAGE>

Title: Method for controlling the conversion of iron-containing reactor feed into iron carbide
Inventor: HAGER JOHN P
IPC: G01N33/00
Filed: 1991-07-23
Granted: 1995-03-23
Abstract: A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a process gas in a fluidized bed reactor (10), and the off-gas from this reaction is analyzed (56) to determine its composition and the temperature (64) and pressure (66). A stability phase diagram is generated based on the temperature. Different regions of the stability phase diagram are representative of different products being formed by the conversion of the reactor feed. Based on relative concentrations of the individual gases in the off-gas and the total pressure, a point is plotted on the stability phase diagram indicative of the favored reaction product. The process parameters can then be adjusted to insure that iron carbide can be produced from the reactor feed based on the stability phase diagram. In one embodiment, the rate of conversion of the reactor feed into iron carbide is controlled.
