Abstract: AUTOMATIC CONTROL SYSTEM     WITH GAIN SWITCHING        Abstract of the Disclosure An automatic control system wherein repetitive pulses, the frequency of which is responsive to a remote condition, such as prime mover RPM, are converted to a DC voltage level.  The voltage level is compared to a reference by a difference ampli-fier to produce an error signal.  Further signals are produced from the error signal which are ultimately used to control the remote condition.  The gain of the amplifier is externally adjustable depending upon conditions relating to the prime mover load conditions.

Abstract: CATHODIC WATER TREATER                 ABSTRACT OF THE DISCLOSURE      An improved unit is disclosed for treating water containing dissociatable mineral salts which tend to accumulate on surfaces exposed thereto wherein the unit is of the type that has an ion neutralizing electrostatic energy producing generator made up of a series of soft iron bars around the water outlet for the treater housing, a plate connected to the ends of the bars and a fine mesh bronze screen surround-ing the bars for subdividing the water into fine streams as it flows into the generator past the iron bars.  The water inlet and outlet of the treater and the housing are arranged and configured to cause the water flowing through the gener-ator in a spiral pattern.  Unexpectedly better results are obtained in this type of water treating unit by providing an aperture in the plate closing the bottom of the generator substantialy at the axis of the spiral water flow pattern and closed by a disc of copper tinned with silver solder on the face thereof remote from the interior of the generator.

Abstract: FLUID-COOLED ELEMENT Abstract A fluid-cooled element for partially defining a hot gas flow passage extending upstream and downstream of a minimum area throat. A serpentine conduit in fluid communication with a coolant source routes cooling fluid within the downstream portion of the element wall bounding the hot gas passage to an internal pocket upstream of the throat. The coolant is thereafter exhausted upstream of the throat as a film over the wall. The upstream wall portion is cooled by the known impingement and film-cooling technique resulting in an element wherein all of the coolant enters the hot gas passage in a low Mach number region upstream of the throat, thereby minimizing momentum losses due to mixing, In the preferred embodiment, the passage throat is defined by a plurality of turbine nozzle vanes, the fluid-cooled element comprising a nozzle band thereof. Flanges support the nozzle within a gas turbine engine and are located upstream of the nozzle throat so as to provide a barrier which minimizes coolant leakage downstream of the throat.

Abstract: ABSTRACT     A pulse signal conditioning circuit.  Repetitive pulse signals can be sharpened and freed of accompanying, unwanted noise manifestations by means of a network of steering diodes and constant current diodes feeding a comparator circuit producing sharp, uniform pulses.

Abstract: MICROCAPILLARY NEBULIZER AND METHOD    Abstract of the Disclosure A pneumatic microcapillary nebulizer adapted to accept a supply of flowable liquid, such as water, and reduce the liquid to an ultrafine dispersion of particles in a propellant gas, such as air.  The microcapillary nebulizer comprises a mixing element having a liquid conduit comprising a microporous capil-lary element having a multiplicity of liquid passages and exit orifices, a gas conduit having a gas orifice and a filming-surface having an edge comprising said gas orifice and communi-cating with said liquid exit orifices.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of using a locking device, which includes a case hardened bolt and a nut which can easily be hand threaded onto it, is provided.  The shank of the bolt above a threaded outer portion is of a reduced diameter such that the nut can turn freely with respect to the bolt.  This portion of reduced diameter is at least as long as the width of the nut.  In use, the bolt is passed through at least two hasps which are to be locked in position with respect to each other.  The nut is threaded onto the bolt to have position in alignment with the portion of reduced diameter.  The threads on the bolt immediately adjacent the nut are then deformed using a hammer and blunt chisel making it impossible for the nut to be removed from the bolt.  When it is desired that the hasps be unlocked with respect to each other, the bolt is destroyed by using a bolt cutter on the shank at a location between the head and the threaded outer portion, and the shank portions are removed from the hasps.
