Potassium 2,6-naphthalene dicarboxylate can be isolated from a Henkel reaction mixture in which it occurs together with potassium carbonate, potassium naphthoate and other potassium dicarboxylates by extracting the other potassium salts with an extract system comprising a major amount of water soluble organic solvent and a minor amount of water, the extract system is evaporated and the extracted salts are recycled to the rearrangement to form additional product.

Methods of preventing neural tissue damage caused by excitotoxicity due to increased release of excitatory amino acids by increasing extracellular concentrations of adenosine in and around the neural tissue are provided. These methods are especially useful in treating neurodegenerative diseases such as Parkinson's Disease, Alzheimer's Disease, Amyotrophic Lateral Sclerosis or Huntington's Disease.

In an RF system which measures the level of materials, the probe includes a measuring electrode and a guard shield. The guard shield is interposed between the electrode and a conductive member, commonly the container for the material, throughout the body of the probe.

A system for setting photographing conditions in which a switch means is engaged with a respective mechanism for setting various photographing informations and converts set values into signs or symbols, and digital information are obtained by selective change-over of the switch means in order to introduce digitalized photographing informations to an operation device.

Thermal conditions inside an oven are measured by a transducer device (1) having plates providing heat absorbent and heat reflective surfaces (2,4) and a thermocouple for measuring the temperature difference between them as a measure of radiant heat. The plates are mounted on a thin thermally insulating layer secured to a heat sink in the form of a copper mass (7,9), and a second thermocouple measures the temperature difference between the heat absorbent surface and the heat sink as a measure of...

A method is disclosed for treating an ischemic condition. The method comprises coadministering topically and internally a vasodilator to a patient having the condition for treating the condition.

A method is disclosed for the analysis of gene expression in human biopsy that is useful in the diagnosis and prognosis of disease and evaluation of risk for disease. The method comprises the steps of compiling data regarding the level of expression of certain individual cloned gene sequences from patients having defined pathological conditions and from normal patients and thereafter identifying sequences that characterize the pathological condition. The data regarding the expression of the indi...

Methods of treating atmospheric conditions including dispensing in the atmosphere surfactants, water-soluble polyelectrolytes or mixtures thereof, methods of dispersing fog by dispensing fog-coalescent materials around an unstable spot in the fog and by dispensing fog-coalescent materials in a substantially straight path through an area to be cleared, and methods of increasing rain by dispensing surfactants, water-soluble polyelectrolytes or mixtures thereof around an unstable spot in a cloud.

A piston-type valve operated by air or other gas characterized by an input supply port and an input control port to which equal pressures are applied, a first signal output port communicating with the supply port when the control pressure decays below a predetermined value, and a manually operated spool valve moveable to a position for disestablishing communication between the supply port and first signal port and also establishing communication between the supply port and a second signal output...

The conditions of hyperkinesis are alleviated by administering an effective amount of caffeine to subjects exhibiting such conditions.
