Abstract: HIGH SWEEP EFFICIENCY STEAM DRIVE OIL RECOVERY METHOD                              ABSTRACT     In a steam flood oil recovery process wherein the oil-containing formation has a natural brine salinity concentration within the range of 10 to 20% by weight, sweep efficiency is improved by injecting steam until steam breakthrough occurs at the production well after which a mixture of steam, a noncondensible gas, and a surfactant comprising a C12 alpha olefin sulfonate is injected into the formation.  The C12 alpha olefin sulfonate forms a stable foam with the formation oil at formation conditions that reduces the permeability of the highly permeable steam swept zones thereby diverting the steam to other portions of the formation containing unswept oil.  If the formation does not contain a natural brine salinity concentration when the salinity of the mixture of steam, noncondensible and surfactant is controlled to a concentration of about 10% by weight by adding a salt thereto.

Title: Hybridization assay with immobilization of hybrids by anti-hybrid binding
Inventor: CARRICO ROBERT J
IPC: C12Q1/68
Filed: 1984-12-12
Granted: 1989-02-21
Abstract: ABSTRACT OF THE DISCLOSURE      A nucleic acid hybridization assay wherein the hybrid formed between the polynucleotide sequence to be detected and the probe is immobilized by binding of an immobilized or immobilized form of an antibody reagent selective for binding such hybrid.  Preferred antibody reagents are selective for DNA?RNA or RNA?RNA hybrids or for intercalated duplexes.  The immobilized hybrid is detected preferably by use of a labeled form of a second such antibody reagent or a labeled form of the probe.  The method dispenses with the need to immobilize either the probe or sample nucleic acids and permits hybridization to proceed between the sequence to be detected and the probe in solution, resulting in rapid rates of hybridization.

Abstract: CYLINDRICAL BALE-FORMING PRESS WITH TORQUE-LIMITING DEVICE     Abstract of the Disclosure This cylindrical bale-forming press comprises sets of belts, bands or the like which define a chamber for forming a bale by rolling up crop products.  At least one stationary roller drives the belts and is itself driven from a main drive shaft.  Some of the guide rollers are movable and are subjected to a biasing action by hydraulic cylinders so as to maintain the belts under tension.  According to the invention, a torque sensor is provided on the main drive shaft of the press and operates to provide an electrical output signal which is operatively connected to electrically responsive valve means in the hydraulic circuitry for controlling the hydraulic cylinders so as to reduce or eliminate the tension in the belts when an excessive resisting torque on the main driving shaft is sensed. In one embodiment wherein the hydraulic cylinders are associated with an expansion valve, the torque sensor is operatively connected to the expansion valve so as to lower the threshold of response of the valve in response to an excessive torque being sensed.  According to a variant, an electrically responsive shunt valve which is movable to a position wherein it interconnects the opposite ends of the hydraulic cylinders may be connected in parallel with the hydraulic cylinders for actuation in response to the output signal of the torque sensor.

To increase the dry residue of the bitumen and to improve the burning-off properties of the mass, 0.3-2 wt-% of additives can be added, in particu-lar Al, Al2O3, B, B2O3, Si and/or SiO2.     The production of the carbon paste is such that the solid fraction is mixed at 130-180°C to a homogeneous mass then the hart bitumen, followed by the soft bitumen added slowly in a highly fluid form accompanied by intensive stirring.          The paste is then intensively mixed further and, after re-moving from the mixer, cooled.

Abstract: SIMPLIFIED RECOVERY OF DATA SIGNALS FROM QUADRATURE-RELATED CARRIER SIGNALS            Abstract A technique is presented for simplifying the recovery of two synchronous data signals having a common symbol rate after each signal has respectively modulated a different one of a pair of quadrature-related carrier signals. In the transmitter, the data signal which modulates one of the quadrature-related carrier signals is delayed relative to the data signal which modulates the other quadrature-related carrier signal. This delay is related to an IF frequency chosen at the receiver. After passing through a noisy transmission channel, the quadrature-related carrier signals are coupled in the receiver to a serial combination of an equalizer and analog-to-digital converter. This combination outputs multiple, substantially distortion-free samples of the data signals each symbol interval. The two data signals are then recovered by selecting a subset of the samples provided each symbol interval.
