A method of treating topical inflammation in mammals by the administration of triamcinolone acetonide-21-valerate in a pharmaceutically acceptable carrier.

A method for shaping gemstones comprising the steps of placing a template in contact with a grinding wheel and locking against translational movement an element holding the template; removing the template from adjacent the grinding wheel and placing the template on the locked holding element at a position spaced from the grinding wheel; placing a guide plate in contact with the template and retaining the guide plate against movement; releasing the locked holding element and permitting movement o...

A correlator comprising a plurality of sets of multivibrators, each set bg serially connected to form a shift register, each multivibrator having a set and a reset output lead, indicating its binary state. The plurality of shift registers comprise a J number of signal shift registers and, in the simplest embodiment, one reference shift register. Each multivibrator is connectable to a clocking source for shifting the states of the multivibrators. One of the multivibrators of each set, at one end ...

An aircraft of VTOL or STOL type is provided with at least one vertically extending duct in the fuselage containing an upper and a lower fan. Air valve means between the fans divide the duct into upper and lower regions and control the air from the upper fan to flow downward and/or into a duct extending rearwardly from the upper region. Other air valve means control the flow of air from a front duct into the lower region.

A pyrometric sensor using a thermistor which is highly resistant to vibrations and heat, comprising a heat-sensing unit formed by inserting a pyrometric thermistor into a metallic protecting tube, connecting lead wires of the thermistor to the protecting tube and a center electrode, and packing a heat-resistant insulating material into said protecting tube. The section of the heat-sensing unit where the thermistor is not located is partly inserted into a hole of an adapter for receiving the prot...

The method of isolating serum or plasma from the formed elements of blood comprising steps of effecting precipitation of the formed blood elements to the bottom of a container, inserting a plug into the container, said plug having normally closed valve means which are openable when pressure within the container is greater than atmospheric pressure. A handle for manipulating the plug functions as a container to collect and remove serum or plasma. In a second embodiment, the handle is removably at...

A light amplifier using a semiconductor, in which an elongated single semiconductor PN junction is used for amplifying an input light injected at an input face provided at one end of the PN junction along the junction plane of the PN junction. The semiconductor PN junction is driven by bias signals applied at a common ohmic electrode and a plurality of ohmic electrodes respectively provided at opposite sides of the PN junction with respect to the junction plane. A plurality of the ohmic electrod...

Using a primary head of water, e.g., from natural source and flowing the water by gravity through an aspirator, a vacuum is produced which is utilized to lift a part of the water from the same source through multiple stages to any desired elevation. The stages may be operated in alternating sequence by selective connection to a common aspirator. Alternatively, by use of multiple aspirators two or more stages may be operated simultaneously for continuous flow. A series of reservoirs arranged with...

Strippers for removal of organic films and deposits, such as the polymeric etch resists employed in the manufacture of semiconductors from inorganic surfaces commonly encountered in the electrical and electronic industries, are composed of solutions of chromium trioxide in mixtures of strong nitric and sulfuric acids containing about 2 percent to about 20 percent water.

The disclosure describes apparatus for instantaneously determining the concentration of a predetermined substance that absorbs radiant energy within a predetermined band of wavelengths in the presence of other interfering substances that also absorb radiant energy in the region of the predetermined band. The determination is made by generating multiple wavelengths of radiant energy. The radiant energy is then sequentially transmitted in a single path through the substances, and the transmission ...
