摘要:
An external indicator device presents parameters associated with stimulation therapy generated by a pulse generator, which may be associated with an external or implantable stimulation device. In this manner, the external indicator device enables a user to visualize stimulation parameters without actually delivering stimulation therapy to a patient via implanted electrodes. The electrical stimulation parameters may include electrical amplitude levels, pulse widths, pulse rates, electrode combinations, and electrode polarities for stimulation generated by the pulse generator.
摘要:
An implantable medical device includes a control circuit for controlling the operation of the device and for obtaining physiological data from a patient in which the medical device is implanted. The implanted device also includes a communication circuit for transmitting the physiological data to an external device. A first power source is coupled to the control circuit and provides power to the control circuit. A second power source is coupled to the communication circuit and provides power to the communication circuit.

Emulsifiers are disclosed which comprise the reaction product of component (I) with component (II). Component (I) comprises the reaction product of certain carboxylic acids or anhydrides, or ester or amide derivatives thereof, with ammonia, at least one amine, at least one alkali and/or at least one alkaline-earth metal. Component (II) comprises certain phosphorus-containing acids; or metal salts of said phosphorus-containing acids, the metals being selected from the group consisting of magnesium, calcium, strontium, chromium, manganese, iron, molybdenum, cobalt, nickel, copper, silver, zinc, cadmium, aluminum, tin, lead, and mixtures of two or more thereof. These emulsifiers are useful in water-in-oil explosive emulsions.
摘要:
An explosive composition is disclosed which comprises a discontinuous oxidizer phase comprising at least one oxygen-supplying component, a continuous organic phase comprising at least one water-immiscible organic liquid, and an emulsifying amount of at least one nitrogen-containing emulsifier derived from (A) at least one carboxylic acylating agent, (B) at least one polyamine, and (C) at least one acid or acid-producing compound capable of forming at least one salt with said polyamine. These explosive compositions can be water-in-oil emulsions or melt-in-oil emulsions. They can also be explosive compositions derived from such emulsions wherein at temperatures below that at which the emulsion is formed the discontinuous phase is solid or in the form of droplets of supercooled liquid.

摘要:
Magnesium-containing complexes are prepared by heating a mixture of magnesium hydroxide, magnesium oxide, hydrated magnesium oxide or a magnesium alkoxide; a carboxylic acid, a sulfonic acid, a pentavalent phosphorus acid, or an ester or salt of any of these; water; and an organic solubilizing agent (which may be liquid or solid at ambient temperature) for the acid or ester. The amount of magnesium is such as to provide a basic composition. The resulting complexes may be obtained in liquid (which may be thickened) or solid form, and are useful as additives for lubricants and fuels and as protective coating compositions for metal surfaces (such as automotive undercoats and frame coatings)..[.This application is a continuation-in-part of copending application Ser. No. 681,627, filed Apr. 29, 1976 and now abandoned..].
