Abstract: An electrode for measuring the pH of a liquid at high temperatures and pressures comprises a first hollow electrode formed of the ceramic which exhibits a pH-dependent potential thereacross and a second electrode provided with a porous ceramic junction. Two flexible-walled members are in fluid communication with the hollow interior of the two electrodes and are surrounded by a chamber whose pressure is kept substantially the same as that to which the electrodes are exposed. However, the chamber is thermally insulated from the hot solution whose pH is being measured. The interiors of the hollow electrodes and the flexible-walled members are filled with the same buffered solution and measuring electrodes are disposed within each of the flexible-walled members. The construction enables the measuring electrodes to be kept at substantially room temperature, thereby reducing chemical attack thereon and eliminates errors in potential measurement due to streaming and thermal diffusion potentials.

Abstract: Apparatus for pumping a liquid from a well comprises a drive unit on the surface, a well-bottom pump unit, two supply lines interconnecting the drive unit and the pump unit and a liquid discharge line extending from the pump unit to the surface for discharge of liquid. The pump unit has a drive piston which is reciprocated within a drive cylinder by applying pressure alternately by means of a changeover valve to the two supply lines. The drive piston drives a double acting driven piston which pumps oil from a well. The changeover valve is controlled by a logic unit which receives signals from sensors measuring the pressure and/or flow rate in a return line.

Abstract: An apparatus for controlling the operation of a door provided with a door closer comprises a body of ferromagnetic material mounted on a portion of a building adjacent the door, an electromagnet mounted on the door (the positions of the electromagnet and body may be reversed), a power supply, an actuator and a timer which connects the electromagnet to the power supply upon actuation by the actuator and disconnects the electromagnet from the power supply after a predetermined interval, thereby allowing the door closer to close the door.

Abstract: Apparatus for supporting a working platform on a roof comprises hook members for engaging the roof cap, a cable extending downwardly from the hook member and a support unit attached to the lower end of the cable and provided with a winch so that it can be moved up and down the cable. The apparatus is used in pairs or larger numbers with an elongate working platform supported on the support unit of each apparatus. The support units can roll up and down the roof on balloon tires and are provided with a chassis section lying close to and parallel to the roof so that if the support units are overloaded the balloon tires will deform and the chassis section will come into contact with the roof, thereby spreading the load and reducing the risk of damage to the roof.

Abstract: Electrochemically generated chromophores are measured by passing a beam of electromagnetic radiation parallel and close to the surface of the electrode at which they are being generated, and collecting the diffracted radiation. The response is so rapid (.about.0.025 sec.) that modulation is practicable and the path length, which is set by the thickness of the electrode, is much greater than in optically transparent electrodes, thus rendering the method very sensitive to weak chromophores or low concentrations.

Abstract: 2-alkyl-5,6-dialkoxy (or 5,6 alkylenedioxy) indenes and indane-1-di- or trialkylammonium salts are useful as calcium antagonists, for example in arrhythmia. The compounds are prepared from the known corresponding 2,5,6-substituted indene-1-dimethylammonium salts by alkylation and/or hydrogenation.

Abstract: To avoid the problem of instrumental drift encountered when using an open-split interface between a temperature-programmed gas-liquid chromatography column and a mass spectrometer, the inert gas supplied to the open-split interface and the interface itself are heated to a temperature above the maximum temperature attained by the chromatography column during the analysis.

Abstract: A container of water is mounted on a motor vehicle and a means for dispensing that water into a passenger compartment of said vehicle is provided. The water will be delivered in the form of vapor. An electrical circuit is formed with a humidity sensing device within the passenger compartment for purposes of actuating the vapor forming and dispensing apparatus. When actuated, water is permitted to flow by gravity from the water container to a heating vessel, where the vapor is formed, from which the vapor may flow through a valved outlet tube to a vehicle heating duct.

Abstract: A process for producing a tri-osmium heteronuclear metal carbonyl compound comprises establishing a reaction mixture comprising an electron deficient cobalt, nickel, iron, molybdenum or rhodium carbonyl, H.sub.2 Os.sub.3 (CO).sub.10 and a solvent in the presence of gaseous hydrogen and recovering the tri-osmium heteronuclear metal carbonyl compound from the reaction mixture. Some of the cobalt, molybdenum and rhodium carbonyls produced are new.

Abstract: Diborane is produced by reacting lithium or sodium borohydride with boron trifluoride in the absence of a solvent, thereby avoiding the dangers associated with the ether solvents previously used in similar reactions. The reaction appears to proceed via hydride abstraction from the borohydride, rather than via the hydride-halide exchange mechanism in the corresponding reaction in ether solution. Yields of about 95% can be achieved.

Abstract: Disclosed is a method for substantially maintaining glycerophospholipid production by cells and for suppressing consequent free fatty acid proliferation in said cells wherein injury or disease has caused normal glycerophospholipid production of said cells to become retarded. Such method comprises presenting said cell with CDP-ethanolamine, CDP-N-methylethanolamine, CDP-N,N-dimethylethanolamine, mixtures thereof or mixtures of these compounds with CDP-choline . Injuries or diseases to which the method has applicability include ischemia, heart disease, stroke, and spinal cord injury. The CDP-compounds may be administered either before or after the onset of the injury or disease.

Abstract: Modified hormones or fragments of hormones are useful in producing antibodies when administered to an animal. Said antibodies in turn cause neutralization of endogenous natural protein hormones. The modification may be accomplished by attaching various kinds of modifying groups to the hormone or fragment. Modification may, for example, be achieved by chemically coupling diazosulfanilic acid groups to the hormone or fragment. The protein hormones to which this procedure can be applied are mammalian protein reproductive hormones such as, for example, Follicle Stimulating Hormone (FSH), or Human Chorionic Gonadotropin (HCG). These modified polypeptides may be administered to animals for the purpose of contraception, abortion, or treatment of hormone-related disease states and disorders, including hormone-associated carcinomas.

Abstract: Apparatus for washing an article, especially an automobile, comprises an article through which the article can pass, nozzles mounted on the framework, a tank provided with means for maintaining pressure therein and connected to the nozzles, a valve for controlling the flow of liquid from the tank to the nozzles and a timer. Upon actuation, the timer opens the valve for a predetermined interval, thereby allowing liquid to flow from the nozzles and wash the article passing through the framework. The pressure within the tank ensures that at least a predetermined quantity of liquid is sprayed during the interval fixed by the timer, even if the pressure in a water main supplying the apparatus fluctuates.

Abstract: Horticultural crops may be stored in an acidic aqueous liquor at a temperature not exceeding about room temperature wherein the pH of the liquor is sufficiently low and the storage conditions are adequately starved of molecular oxygen to retard spoilage of the stored product. Following termination of the storage, the stored product is preferably at least partially neutralized at a temperature of between about 40.degree. and 60.degree. F. with a neutralizing agent to raise the pH of the stored product. When green horticultural crops are thus stored and thereafter boiled, a strong green coloration is produced and green pigments can be separated by solvent extraction.

Abstract: Implants, microbeads and microcapsules suitable for injection into an animal body comprise cross-linked but physically-native albumin and a non-albumin substance, for example a steroid or an enzyme. The microcapsules are formed under mild conditions (not above 37.degree. C. and pH 4-10) from either a native albumin and a non-denaturing bi-functional cross-linking agent or a self-polymerizable albumin derivative. The method may be used to immobilize living cells such as yeast.

Abstract: Method, apparatus and system for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. Conveyor belts transport the objects to be sorted along the zone for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilience are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of the sorting zone oscillatory surfaces, a multistage sorting system is made available.
