Abstract: Abstract of the Disclosure: The oscillation generator includes an oscillator circuit, a push-pull amplifier with inductive positive feedback connected in the circuit, a piezoceramic atomizer vibrator element, and a load-dependent regenerative feedback coupling connected to the circuit. The coupling is in the form of a tuneable frequency-selective sensor, such as a parallel resonance circuit, having outputs con-nected to the inputs of the amplifier. A positive feedback trans-former may be connected to the output of the amplifier and to a selective circuit which includes the vibrator element and a re-sonance circuit and which is connected in series with the parallel resonance circuit. The amplifier may be a differential, transistor amplifier. The oscillation generator is used in inhalators, fuel atomizers, humidifiers and ink atomizers, etc. As compared to prior art devices, the invention uses fewer parts, and is less affected by load changes, so that it will start reliably and will only operate at the atomizer resonance.

Abstract: PATENT APPLICATION of ARTHUR KARP    for SLOW-WAVE CIRCUIT FOR TRAVELING-WAVE TUBES                           ABSTRACT      In a traveling-wave tube for very high frequencies the slow-wave circuit is formed of four metal combs having teeth pointed toward the electron beam.  The combs are arranged in two pairs.  The teeth of the two combs in each pair extend inward from opposite sides of the beam and are axially aligned to form the electrical equivalent of a half-wave bar or ladder structure. They may or may not be joined at the tips because those are low-current points. The teeth of one pair are at right angles to those of the other pair and are displaced axially to interleave with them. Each comb is preferably made from A single piece of copper to provide better dimensional precision, low circuit loss, mechanical durability and high thermal capability.     2rbn31379             - 1 -    79-16

Abstract: ABSTRACT OF THE DISCLOSURE     A bridge plug tool is disclosed, for temporarily plugging off a well casing to perform a downhole operation, such as cementing, or acidizing.  The tool includes a mandrel having separate and spaced threaded segments thereon.  During running-in of the tool into the well casing, one threaded segment engages a set of control members to keep the mandrel in place and to prevent it from shifting longitudinally with respect to the tool. In the set position the control members are disengaged from the mandrel and the other threaded segment engages a set of lock members.  By applying a weight on the mandrel after threaded engagement of the mandrel with the lock members, a set of slip members and packing elements are caused to engage an inner surface of the casing wall to set the tool in position in the well casing.  When the downhole operation is finished, the mandrel is rotated to disengage from the lock members and to re-engage the control members.  This sequence disengages the slip members and packing elements from the casing wall so the tool can be retrieved from the casing, or re-set at another position in the casing. 28,422-F

Abstract: ABSTRACT OF THE DISCLOSURE        A digital signal transmission system whereby the plural-bits-in-one-word digital signals are transmitted serially. According to this system, when the amount of data per unit time increases and the clock frequency of data is extremely high, a word synchronizing signal is input for each word so as to effect clock synchronization of data based on the word synchronizing signal, thereby allowing easy reading of each data bit.  Detec-tion can be facilitated by differentiating the format of the word synchronizing signal from that of the data clock signal, for example by varying the pulse period or pulse width.  Further, by assembling a plural number of words into a block so that the block units are indicated with at least one bit in the words being signalled as a block flag bit, it becomes possible to treat the data in excess of the word units, allowing increase of the substantial bit number without increasing the bit number in one word.

Abstract: PROCESS FOR REMOVING CARBON BLACK FROM AQUEOUS SUSPENSIONS    ABSTRACT OF THE DISCLOSURE:    The invention relates to a process for removing carbon black from an aqueous suspension obtained by washing a gas containing carbon black with water. To this end, a gas stream comprising hydrocarbons and at least one inert gas is introduced into a suspension having a solids content of from  0.5 to 4 % by weight, at a temperature of from 10 to 80° C. In so doing, the carbon black agglomerates and collects on the surface of the suspension water from which it is separated, for example by skimming it off. The gas stream is produced by passing inert gas over the separated carbon black containing the hydrocarbons and heated to 200 to 400° C, the carbon black being converted into a dry, free-flowing material.

Abstract: ABSTRACT OF THE DISCLOSURE              The present invention provides, in combination, a drive for a boat of the outboard or inboard/outboard type, said drive having a propulsion means for producing a slipstream as it moves through the water; the drive being turnable about a steering axis to provide a steering effect on the boat, and a rudder to assist in steering the boat at speeds below a selected speed.  A mechanical coupling connects said rudder directly to said drive so that both the drive and the rudder turn together about said steering axis as the boat is steered.  The mechanical coupling between said rudder and said drive includes means defining a pivot axis generally transverse  to said steering axis permitting the rudder to pivot relative to said drive between a lowered position where the rudder can react to the slipstream of the propulsion means and a raised position where said rudder is substantially removed from the slipstream.  The pivot axis is located relative to the rudder such that forces acting on said rudder in its lowered position by virtue of the motion of water relative thereto provide a moment about said axis capable of pivoting the rudder about said axis and moving same toward the raised position as the relative speed between the water and the rudder approaches a predetermined value to make the steering of the boat substantially independent of the rudder.

Abstract: Abstract A storage container for solid particulate materials includes a source of 'lubrication' gas coupled to a fluidiser.  The fluidised particulate materials are carried from the container by a stream of transport gas.  A deflector placed over the container outlet constrains the fluid flow in a substantially horizontal path to prevent the outlet becoming blocked by the solids when the gas flow is cut off.  The proportions of particulate material can be varied by selectively varying the pressure in the container, where the container is a pressure vessel.
