Title: Two-dimensional crystallization technique
Inventor: KORNBERG ROGER D
IPC: C07K16/00
Filed: 1983-11-09
Granted: 1987-08-13
Abstract: Methods and compositions involving two-dimensional ordering of organic polar solvent soluble organic macromolecules. Lipid monolayer forming molecules are bound covalently or non-covalently to organic macromolecules soluble in polar solvents, whereby the macromolecules are allowed to become oriented in two-dimensions to form an ordered, low free energy, including crystalline, layer of macromolecules. The macromolecules may then be further combined with other moieties to create additional layers, to be cross-linked or otherwise modified, andlor separated from the lipid monolayer. The resulting ordered layers can be used for a variety of purposes, in crystallographic techniques for structure determination and structural relationship determinations, in optics, as polymers, films, and the like.

Title: A method and apparatus for sewing mitered corners on a split needle bar sewing machine
Inventor: MARTELL CHARLES RONALD
IPC: D05B35/10
Filed: 1984-02-22
Granted: 1988-07-21
Abstract: A semi-automatic split needle bar sewing machine (10) includes a sewing machine (12) which is driven by a motor (26) that drives a left needle (22) and a right needle (23). A presser foot (24) is operated by presser lift actuator (30). The needles (22) and (23) can activate in unison or independently by use of fall out actuators (41) and (43), respectively. A control chassis (50) includes a microprocessor controller (51) that is programmable through an input panel (44). An edge detector (40) detects the edge of the material to provide feedback for the microprocessor controller (51). The microprocessor controller (51) is operable to sew a decorative pattern with mitered corners by sensing the pivot point of the mitered corner and automatically disengaging one of the needles (22) or (23). The microprocessor controller (51) then continues single needle sewing around the apex of the mitered corner by counting a predetermined number of stitches and varying the length of the stitches such that the needle is in the correct position when the single needle sewing again arrives at the pivot point on the other side of the mitered corner. In this manner, it is not necessary for the operator to manually adjust the length of the stitches around the apex of the mitered corner.

Title: Trilevel sandcastle pulse encoder
Inventor: HETTIGER JAMES
IPC: H04N9/44
Filed: 1984-12-13
Granted: 1988-07-21
Abstract: In a color TV receiver incorporating automatic kinescope bias (AKB) control circuits, a first train of monolevel pulses with timing suitable for retrace blanking purposes and a second train of monolevel pulses with "backporch" timing appropriate for burst gating purposes are applied to a circuit serving to generate at a first terminal a train of bilevel pulses exhibiting a first voltage level during periods of overlapping of the pulses of the first and second trains, and exhibiting a second, lesser voltage level during the remaining, non-overlapping portions of the pulses of the first train. A resistor interconnects the first terminal with a second terminal. A keyed voltage source, responsive to a third train of monolevel pulses timed to indicate recurring kinescope bias control intervals, develops a voltage of a third level, intermediate the first and second voltage levels, at the second terminal during the recurring control intervals. The keyed voltage source exhibits, during the control intervals, an output impedance significantly lower than the impedance exhibited by the interconnecting resistor. During periods intervening successive ones of the control intervals, the voltage source is effectively disabled and exhibits an output impedance significantly higher than the impedance exhibited by the resistor.

Title: Constant tension hoisting system
Inventor: CHRISTISON S GRANT
IPC: B66D1/52
Filed: 1985-09-12
Granted: 1989-03-02
Abstract: A constant tension hoisting system is provided for raising and lowering an object between a platform and a surface undergoing vertical motion relative to the platform, such as raising and lowering a lifeboat from a seagoing vessel to the sea in rough weather. The system operates in a normal hoisting mode to raise or lower the object, and in a constant tension mode when the object is supported on the surface. The system is changed from the normal hoisting mode to the constant tension mode at the moment when the object being lowered is first supported by the surface, and a slack condition exists in the cable. The changeover from the normal hoisting mode to the constant tension mode, is performed by a solenoid-operated mode selector responsive to a proximity switch operated by a lever arm engaging the cable. The hoisting system is operated by a single, manually-actuated control lever, which mechanically activates the proximity-type control switches. An auxiliary motor connected to a ring gear of a planetary-type final drive operates the hoisting system in the constant tension mode, while a main motor operates the system in the normal hoisting mode.

Abstract: A method for determining the presence of a polynucleotide analyte in a sample suspected of containing the analyte is disclosed. The method comprises combining in an assay medium the sample and first and second polynucleotide reagents complementary to the analyte. Each of the first and second reagents hybridize with a different region of the analyte. The first reagent contains means for rendering the first reagent non-covalently polymerizable. The second reagent contains means for rendering the second reagent detectable. The sample and the first and second reagents are combined in the assay medium under conditions for polymerizing the first reagent wherein the second reagent becomes bound to the polymerized first reagent only when the analyte is present in the sample. A determination is then made as to whether the second reagent has become bound to the polymerized first reagent. The method has broad application for determining the presence of a polynucleotide analyte such as DNA, RNA, the genomes of viruses, bacteria, molds, fungi, and fragments thereof, and the like. Preferred means for rendering the first reagent non-covalently polymerizable includes a repeating oligonucleotide sequence covalently bound to the first reagent.
