Abstract: SENSING SWITCH FOR A MAGNETICALLY   COUPLED COMMUNICATIONS PORT         ABSTRACT OF THE DISCLOSURE           A magnetically coupled communications port includes a switch for providing an enable signal upon coupling of a detachable magnetic coupler assembly to a fixed coupler assembly.  The switch is magnetically activated and is positioned on the fixed coupler assembly in proximity to one end of a cylindrical slug of a magnetically conductive material.  The opposite end of the cylindrical slug is positioned co-planar with an external face portion of the fixed coupler assembly.  When the detachable magnetic coupler assembly mates with the fixed coupler assembly, contacting the face portion and the co-planar surface of the cylindrical slug, magnetic flux from the detachable magnetic coupler is concentrated through the slug causing the magnetically activated switch to switch from an inactivated position to an activated position.

Abstract: ABSTRACT    A release mechanism is provided  for releasably joining two objects such as straps, cables, ropes, or the like as well as two rigid members such as pipes, tubing, beams, columns, or the like.          The  mechanism  is  usable  for  releasing  loads  which  are  under tension and, in certain embodiments, also transmit compression and torsional  forces.   One  mechanism  includes  a  pair  of  pivoting plates connected to the ends of a bifurcated strap.  The plates engage  elongated  surfaces  on  a  root member  connected  to  an opposite strap.   An indexing arrangement is provided to prevent relative  sliding  movement.   The  plates  are biased  for  outward movement.  Outward movement is prevented by releasable securement links or straps.  An alternative form of securement is provided in the form of a sliding enclosure.   An alternative embodiment for flexible or rigid members is provided in the form of a central root surrounded by outwardly pivoting  leaves.   Pivoting members connected to the leaves engage projections on the root member.  A latch and release mechanism controls the movement of the leaves.          A  rope  release mechanism has  a pair  of  plates  received by  a transverse root connected to one rope.   The plates are connected to  the  bifurcated  end  of  the  other  rope.   The  root  has  a circumferential  groove  which  receives  a  rubber  band  which releasably secures the bifurcations.  The ends of the plates are releasably secured together.

Abstract: SUPERCRITICAL FLUID MOLECULAR SPRAY FILM     DEPOSITION AND POWDER FORMATION                    ABSTRACT OF THE DISCLOSURE Solid  films  are  deposited,  or  fine  powders formed,  by dissolving  a solid material  into  a super-critical fluid solution at an elevated pressure and then rapidly expanding the solution through a short orifice into a region of relatively low pressure.  This produces a molecular spray which is directed against a substrate to deposit a solid thin film thereon, or discharged into a collection chamber  to collect  a  fine  powder.   Upon expansion  and  supersonic  interaction  with  background gases in the low pressure region, any clusters of sol-vent  are  broken up and  the  solvent  is  vaporized  and pumped away.   Solute concentration  in the  solution is varied  primarily  by  varying  solution  pressure  to determine, together with flow rate, the rate of deposi-tion and to control in part whether a film or powder is produced and the granularity of each.  Solvent cluster-ing and solute nucleation are controlled by manipulating the rate of expansion of the solution and the pressure of the lower pressure region.  Solution and low pressure region temperatures are also controlled.

Abstract: HYDRAULIC PROXIMITY PROBE          ABSTRACT:       An  hydraulic  proximity  probe  arrangement  for determining the spacing of the surface (26) of a rotat-ing body (10) from another fixed body as it rotates in a fluid medium.  The body is provided with a plurality of circumferentially and equally spaced surface irregular ities  (12) of like size and shape, such as indentations or projections, and at least a pair of probes (18,20) are circumferentially spaced around the body, each being axially spaced an equal distance from the body's sur-faces when at rest.   The probes pick-up pulsations in the  fluid medium caused by the rotating body,  the amplitudes of which are indicative of the spacing of the surface of the rotating body from the end of the probes. These pulsations are signalized (28,30) and the resul-tant signals are compared with calibrated deviation signals to provide data indicative of the spacing of the body's surface from a reference point during rotation of the body.

Abstract: ABSTRACT           An  improved  pipe cleaning machine of the  type  which uses an elongated,  flexible coil spring or plumbers snake formed of   helically  wound  spring  wire  which  is  housed  within  a rotatable,  hollow spring storage reel and is withdrawn therefrom for  insertion into the pipe to be cleaned.   The machine of  the present  invention  embodies a novel one-piece  rotatably  driven drum  or  housing having a forward guide portion for guiding  the dispensing  and retraction of the spring and a partitioning  wall which  partitions the drum into a first portion in  communication with the forward guide portion and a second portion which closely contains the spring in a coiled configuration.   The partitioning wall  terminates in an end portion which is spaced from the  rear wall of the drum a predetermined distance to define a  restricted guide  passageway communicating with the spring storage  compart-ment.   The  restricted  size of the storage compartment  coupled with  the  restricted size and location of the  guide  passageway effectively  prevents  backlooping  and tangling  of  the  spring within the storage compartment.

Abstract: ABSTRACT OF THE DISCLOSURE    A fixed bed layer of a reactor column for the execution of anaerobic decomposition processes, which column is divided by screen partitions into segments one above another with intermedi-ate spaces for gas discharge from the column through discharge funnels into one or more corresponding, ascending pipes.  Addi-tional devices for the introduction of liquid or gas into the individual fixed bed segments produce turbulence and remove excess sludge from the fixed bed layer.  Annular guide elements project from the inner wall of the column underneath the funnel and have a constricted cross section which defines an annular channel to the next column segment.  Thus, a liquid stream is not blocked during optimal gas collection in the funnel.  The funnels are preferably installed in the screen floor of the subsequent column segment.

Abstract: Abstract of the Disclosure A pattern matching vocoder includes first and second reference pattern memories, a pattern matching processor, and a frame selector.  The first pattern memory stores reference vector patterns clustered by a distribution of the number of times of occurrence for spectral envelope vectors of an input speech signal.  The second reference pattern memory stores reference vector patterns clustered by pole frequencies, pole bandwidths and a bandwidth of the input speech signal.  The pattern matching processor divides the bandwidth of the speech signal into frequency regions and performs pattern matching using, as spectral envelope vectors, power ratios between the frequency regions.  The frame selector performs frame selection using, as an evaluation value, a total distortion consisting of a vector distortion caused by pattern matching and a time distortion caused by frame selection with a DP scheme.

Abstract: ABSTRACT OF THE DISCLOSURE A drive system for a down hole oil well pump includes a cylinder assembly which defines first and second cylinders.  A pump rod which includes first and second pistons, each disposed in a respective one of the cylinders, is coupled to the down hole pump.  A hydraulic accumulator supplies a resilient biasing force to one of these pistons to counter the weight of the ram interconnecting the pump rod and the down hole pump.  A hydraulic pump supplies pressurized hydraulic fluid which is alternately directed against upwardly facing and downwardly facing piston faces of the pump rod to cause the pump rod to oscillate, thereby driving the down hole pump.  Fluid level sensors deactivate the hydraulic pump when the oil level in the oil well falls below a pre-set level.
