A method is disclosed utilizing the optically pure (S) configurational enantiomer of metoprolol for treating cardiovascular disorders while reducing undesirable side effects associated with the administration of beta-blockers.

Abstract: The optically pure R(-) isomer of albuterol, which is substantially free of the S(+) isomer, is a potent bronchodilator for relieving the symptoms associated with asthma in individuals. A method is disclosed utilizing the optically pure R(-) isomer of albuterol for treating asthma while minimizing the side effects associated with chronic administration of racemic albuterol.

Abstract: Methods and compositions are disclosed utilizing optically pure R(-) ketoprofen for the treatment of pain including, but not limited to, pain associated with toothaches, headaches, sprains, joint pain and post-surgical pain, for example dental pain and ophthalmic pain, while substantially reducing adverse effects including, but not limited to, gastrointestinal, renal and hepatic toxicities, and leukopenia, which are associated with the administration of racemic ketoprofen. Optically pure R(-) ketoprofen is also useful in treating pyrexia while substantially reducing the adverse effects associated with the administration of racemic ketoprofen.

Abstract: The optically pure isomer of nitrendipine having anti-hypertensive activity, is a potent anti-hypertensive drug for reducing blood pressure in individuals without the undesirable side effects associated with administration of a racemic mixture of nitrendipine. A method is disclosed utilizing an optically pure isomer of nitrendipine for treating hypertension while reducing undesirable side effects associated with nitrendipine.

Abstract: A method for maintaining switchover between a backup and degrading active processor, which switchover is transparent to a terminal accessing the active processor with atomic transactions. The backup processor prepares for an outage by the active processor by synchronizing, tracking, and monitoring the active processor's log entries. When the active processor fails, the backup processor performs the necessary recovery processing and takes over user-transactions processing as the new active processor.

Abstract: Disclosed is a method of inducing and maintaining anesthesia while avoiding concomitant liability of adverse effects comprising administering by inhalation to a warm blooded animal in need of anesthesia an amount sufficient to induce and maintain anesthesia but insufficient to cause said adverse effects, of (S)-isoflurane or (S)-desflurane, substantially free of its (R)-stereoisomer. Also disclosed are novel compositions of these compounds for use in the above disclosed method.

Abstract: A method and composition are disclosed utilizing the pure S(+) isomer of fluoxetine, which is a potent antidepressant substantially free of adverse toxic or psychological effects, having a rapid onset of action and a high response rate.

Abstract: An improved air treatment device that will reduce or eliminate exhaust pollutants of internal combustion engines, by treating air prior to its introduction into the carburetor with ultra violet rays and heat, resulting in more complete combustion. The device provides an improved pre-heater for the air by utilizing the circulation of existing fluid as a heat source.

Abstract: A log unloading apparatus for a batch former in which a receiver platen is moved by a batch of logs as they are pushed out of the batch former. The logs are supported intermediate their lengths by an intermediate log support member which initially is abutting the batch former, but, upon movement of the logs from the batch former, can be drawn out with the receiver platen to provide support for the logs intermediate their length but also providing two spaces or gaps sufficient to receive the forked tines of a grapple.

Abstract: Exhaust pollutants of a vehicle are reduced by providing dry, substantilly moisture-free air which is mixed with the fuel. The conventional air filter is removed and replaced by a housing containing a plurality of sealed glass tubes having inert gas therein which treats the air by subjecting it to ultraviolet rays and additional heat. The air has been initially heated to remove the moisture and subjected to an ultraviolet treatment before it reaches the housing.

Abstract: A torque transmitting drill string tool is provided that includes an outer member and an inner member telescopically arranged. Spline means between said outer member and said inner member transmits torque. A spring means is positioned between the outer member and the inner member. Means are provided for adjusting the position and/or pre-load of the spring means without disassembling the tool.

Abstract: A drill string reamer-stabilizer includes a main body adapted to be connected as an element of a rotary drill string. Individual bearing shafts are mounted axially along the exterior of the main body supporting roller cutters that engage the wall of the borehole. Seal units are positioned around each bearing shaft between each roller cutter and bearing shaft to define a lubricant space. The seal units retain lubricant in the lubricant space and prevent contaminating fluid and materials in the borehole from entering the lubricant space. At least one seal unit comprises an annular cup-shaped elastomer seal member with an annular lip mounted in an annular seal gland in the roller cutter. The seal gland has an inner side adjacent the lubricant space and an outer side exposed to the fluid and materials in the borehole.

Abstract: A hydraulic jarring tool includes a system for externally adjusting the sleeve valve flow rate mechanically. The jarring tool includes an outer member and an inner member telescopically arranged. Spline means between said outer member and said inner member transmit torque. A hammer and anvil system provides a jarring effect upon actuation of the tool. An upper seal and lower seal provide fluid seals between said outer member and said inner member. A working fluid is maintained in a working fluid chamber between the upper and lower seals. A detent means provides a tripping action to produce the jarring effect. The detent means includes a sleeve valve with an internal needle valve that is adjustable to change the fluid restriction. An exterior port allows a wrench or tool to be inserted to adjust the needle valve and provide a selectable size passage that produces the detent action by the slow metering of hydraulic working fluid.

Abstract: A method is described for significantly reducing Douglas-fir beetle (Dendroctonus pseudotsugae Hopk.) attacks on felled trees, through the use of the Douglas-fir beetle anti-aggregative pheromone, 3-methyl-2-cyclohexen-1-one (MCH), a highly volatile and water soluble material. Controlled release formulations of MCH can prevent the buildup of outbreak population of beetles in susceptible trees. Five controlled-release granular formulations were developed that eluted 3-methyl-2-cyclohexen-1-one (MCH) in the laboratory at a rate .gtoreq.0.5 .mu.g/hour for 60 days. The inert components of these formulations consisted either of a wax-coated molecular sieve, polyethylene emulsion-coated ground corncob or dimer acid polyamide beads. These formulations and a liquid standard were applied 9 May (1975) just prior to Douglas-fir beetle (Dendroctonus pseudotsugae Hopk.) flight to plots containing single, freshly felled Douglas-fir (Pseudotsuga menziesii var. glauca) trees.

Abstract: Chemically and physically stable herbicidal, water-emulsifiable, liquid concentrates containing 4-amino-6-t-butyl-3-(methylthio)-1,2,4-triazin-5-one (metribuzin) and 2-chloro-N-(2,6-diethylphenyl)-N-methoxymethylacetamide (alachlor) are dissolved with an appropriate emulsifying agent in alkylbenzenes, especially xylene. The presence of the amide ingredient in about 3 to 5 times the weight of the triazinone ingredient permits the triazinone ingredient to be dissolved to the extent of as much as 12% by weight in xylene compared with only 4% in the absence of the amide.
