Abstract: Abstract A buffer amplifier suitable for use as an input amplifier for an oscilloscope comprises a hybrid FET-bipolar transistor source follower input stage and a complementary emitter follower output stage. Both the input and output stages include bootstraps to elimi-nate  thermal  transient  response  aberrations,  to  in-crease input impedance, and to maintain standing cur-rent in the output stage. Other attributes include a very short response time for high bandwidth operation, and high linearity.

Abstract: ABSTRACT OF THE DISCLOSURE A procedure Is provided for the recovery of precious metal lost from precious metal-containing catalysts, for example, the precious metal-containing catalysts which are used in the production of nitric acid by ammonia oxidation.  In more detail, a getter for recovery of precious metal lost from a precious metal-containing catalyst operating at elevated tempera-ture comprises an agglomeration or assemblage of unwoven, randomly oriented, fibres made from a  metal selected from  the group consisting of ruthenium, palladium, iridium, platinum, gold, silver, and rhodium or alloys contain-ing one or more of these metals.  The fibre agglomerate so provided has been found to give a performance at least equivalent to, and generally better than, that of conventional getter gauze packs in the manufacture of nitric acid. Further, use of the agglomerates showed considerable metal saving compared with the use of standard getter guazes.  The use of fibres overcomes the tedious and expensive process of fine wire drawing and weaving.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to sulfonated thermoplastic polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits, and lift cuttings from the holes in the drilling opera-tion for oil and gas wells.  The sulfonated thermoplastic polymers have 5 to 100 milliequivalents of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion.  A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated polymer, wherein the polar cosolvent increases the solubility of the sulfon-ated polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved pump for lifting water from an underground source utilizes a wind motor for driving an oil-less air compressor eliminating oil contamination of ground water which is forced to the surface.  The wind motor is movable to face the wind by means of a novel swivel assembly which also eliminates the formation and freezing of condensate within the airline from the compressor.  The propeller blades of the wind motor and the tail section are formed from a pair of opposed convex air foil shaped surfaces which provide the propeller blades and the tail section with fast sensitivity to slight changes in wind direction and speed.  A novel well tower for supporting the wind motor and compressor and for lifting the water from the underground source is an optional modification which requires no welding and eliminates the problem of condensate freezing in the airline going to the wall. The wind driven air pump disclosed is lightweight, can be easily installed, is relatively inexpensive to produce and is virtually maintenance-free and capable of operating in winds exceeding 100 miles per hour.

Abstract: Abstract:    The invention relates to a terminal box for the motor-compressor of a refrigeration device.  The terminal box contains internal divisions for the starting relay and the thermal protection relay employed with such refrigeration devices.  The internal division are separated by walls that thermally isolate the two relays.  The electrical terminals are located on a wall of the box that, when installed on the motorcompressor located inside a suitable cabinet, face the service operator for ease of attachment and removal of the electrical connectors.  The box is suitably shaped that it does not project outwardly by a significant distance from the motorcompressor when attached thereto.  The terminal box conveniently houses all of the external elements of the motorcompressor in a space-saving manner while allowing for easy access.

An RF coil coccal surrounds the tube and is driven by an RF generator.  The total wire length of the coil is approximately 0.7 to 1.3 (depending on specific electrical properties and volume of the treated material) times the wavelength of a basic driving frequency provided by the generator.  The output of the generator is supplied to the coil via a 50-ohm coaxial cable and a matching impedance.  The coil may be driven by frequencies corresponding to integral multiples of one-half the basic wavelength, to enable shifting the heat focus volume along the coil axis from the normal centered location on the axis produced by full-wave excitation.

Abstract: ABSTRACT OF THE DISCLOSURE         A dispenser package for flowable substances of the type where the flowable product is contained within a flexible pouch adhered to a relatively stiff material and may be opened along a fault line or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends toward one another into a "V" shape containing one or more dimples, pyramidal shapes or other protrusions on the fault line or fault area.  The protrusion not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed.  The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed.  A sponge-like material also may be compressed within the package shaped so that a portion will project from the package on opening for use as a swab for application of the contents.

A closure anvil is movable under the die. The die is mounted with a small clearance in the die holder and has an indentation along one generatrix of the outer surface. Thus, the die will be ruptured along the generatrix line during the compression stroke. This does not jeopardize functionality but rather makes die replacement easier. The vertical arrangement eliminates eccentric wear as due to the weight of the horizontally moving elements of known briquetting machines, and facilitates the intaking of the pre-compressed material.

Abstract: ABSTRACT OF THE DISCLOSURE         A combination weighing machine has a plurality of scales that are periodically dumped and reloaded with pro-ducts from a bulk container.  In each cycle of machine opera-tion, the loaded scales are surveyed, and a combination of the scales which most accurately yields a desired target weight is duped into a single package.   The dumped scales are then reloaded and the process is repeated.  Each of the scales has an associated vibratory feeder and accumulator which receives the product from the bulk container and dis-penses the product to the scale as needed.  In order to feed the scales with loads that provide a large selection of com-binations close to the target weight, a control for the vi-bratory feeders regulates the duration and amplitude of the vibrations in accordance with the loads measured in preceding machine cycles.
