Abstract: ABSTRACT              A process is disclosed for producing hydrogen and oxygen gasses from water which includes having water in a cavity which has a selected resonant frequency and applying of voltage potential to exciter elements in contact with the water in the cavity so that one elements maintains a positive charge and the other a negative charge.  The voltage potential is pulsed at a frequency matching the resonant frequency of the cavity.  The apparatus includes      a spherical shell which is a first exciter element formed of an electrically conductive non-reactive material and defines the boundary of a cavity. The cavity has a pre-determined resonant frequency and a second exciter element of the same material as the first exciter element is located within the cavity in selected spaced relationship therewith.  Water can flow into the cavity and gasses produced outflow from the top of the cavity, such gasses being obtained from the water in the cavity when an electrical pulsating potential is applied to the exciter elements.

Abstract: ABSTRACT OF THE DISCLOSURE An upstanding side wall comprises wood plank members having opposite planar outwardly facing vertical surfaces. The longitudinal side edges are bifurcated symmetrically with respect to a vertical central plane bisecting the two planar surfaces.  The bifurcations are curved in horizontal cross-section to form a pair of curved tongues with an intermediate concave curved recess between the tongues.  Each recess receives a mating tongue of an adjacent vertical plank member.  Each member is symmetrical about the central plane and also about a midplane perpendicular to the central plane and midway between the bifurcations.  Alternate members may comprise members corresponding substantially to a half of such a member cut along the central plane.  A low density soft foam sealant is applied in a groove at the bottom of each recess.

Abstract: Abstract of the Disclosure Synthetic seaweed for use in inhibiting coastal erosion comprises an elongate anchor with strips of flexible non-woven material connected to the anchor.  The strips may be buoyant with or without tabs of closed cell, low density foam affixed to the free end portions thereof to enhance the buoyancy of the strips whereby they maintain a generally upright position under water.          Also, the strips are treated to inhibit or prevent marine growth from forming on the surface of the strips.  Such treatment may include an antifouling agent or a smooth film, applied to the strips as a laminate or extruded directly onto the strips, for example.  In use, the anchor rests upon the bottom of the sea and the submerged flexible strips of non-woven material extend upwardly therefrom.  The strips sway in the ocean water thereby reducing currents in the surrounding water which permits accretion of suspended sand and promotes sedimentation of solid particles.

Abstract: ABSTRACT OF THE DISCLOSURE           An inertial measuring unit gyroscope wheel dynamic braking and sequence inhibiting circuit is disclosed.  The circuit comprises a first counter for counting a specified time interval and digital logic circuitry for applying an in-phase signal to the phases of a multiphase electric induction motor driving a gyroscope wheel during the time interval, for example, a vertical gyroscope motor wheel.  By placing in-phase signals on the inputs of a multiphase electric induction motor, the motor is brought completely to rest in a short time by dynamic braking.          In a preferred embodiment, a second counter counts a second specified time interval after the first time interval has term-inated, during which second time interval a second electric induction motor is dynamically braked, for example, an azimuth gyroscope  wheel motor.  During the time period when the motors are braking, a signal is fed back to an automatic sequencing circuit to inhibit further sequencing of the inertial measuring unit.

Abstract: ABSTRACT OF THE DISCLOSURE        A system for mooring a ship-shape floating production system using a riser tensioned by a weight type motion compensation system.  The riser is attached to the ship by a rocking beam that has a weight attached at one end of the beam to balance the vertical load component of the riser attached at the other end of the beam.  A rocker arrangement is used whereby the beam support point moves to compensate for the inertial forces of the weight caused by the vertical accelerations of the tanker.  Thus the high load fluctuations and hence poor riser fatigue life usually associated with weight type motion compensators is minimized.  A gear arrangement is used to transmit horizontal loads.  The overall arrangement provides a totally self-contained motion compensation and riser handling system that requires minimal ship  modifications and is independent of significant self-induce wave loading.

Abstract: ABSTRACT           There is described an arrangement for truncating two's complement numbers in a symmetrical manner so that truncated values of both positive and negative numbers tend toward zero.  Symmetrical truncation is performed by discarding the least significant bits (LSB's) of positive values and by algebraically adding "one" to the truncated negative value when at least one of the discarded LSB's is a logical "one" value.  An illustrated arrangement to perform an N bit truncation includes an incrementer, a two input AND gate and an N-input OR gate.

Abstract: ABSTRACT OF THE DISCLOSURE     A  linear detector  (61)  for use in  a coarse positioning servo system of an optical system.  The linear detector produces an error signal  having an  amplitude  linearly proportional  to  the distance that  a relatively narrow strip of  light  energy  (63)  falls  on  a collection surface (62) of the detector as measured relative to a fixed  reference point on  said collection  surface.   Two  reference signals  (65,  66)  are  derived  from  circuitry  associated with the collection surface.  A first reference signal (65) has an amplitude proportional to the intensity of the focused light energy and the location  that  said  light  energy falls  on  the  collection  surface relative to a first reference point.  A second reference signal (66) has an amplitude proportional to the intensity of the focussed light energy  and  the  location  that  said  light  energy  falls  on  the collection surface relative to a second reference point.  The sum and difference of the amplitudes of the first and second reference singles  are  derived  to  produce  sum  and  difference  signals, respectively.  The difference signal is divided by the sum signal to produce the desired error signal  (67), which error signal  has an amplitude that is substantially independent of the intensity of the focused light energy.

Abstract: Abstract Method and Apparatus For Accelerating a Particle Beam A travelling wave resonant ring accelerator method and apparatus is disclosed which includes a generator of radio frequency source energy and a low dispersion accelerator waveguide interconnected by a microwave bridge network that combines said source energy and said accelerator remnant energy and directs said combined energy to the input of the accelerator waveguide under desired conditions with the bridge balanced.  The method and apparatus simultaneously maintain (a) the optimum beam-wave phase relationship in the accelerator waveguide and (b) the correct electrical length of the resonant ring, regardless of wide variations in ambient temperature, by maintaining a balanced bridge condition by automatically adjusting the frequency of the source energy. Electromagnetic interference is avoided by incorporating a high power modulator high voltage switch in a compact coaxial transmission line to provide a contraflow circuit for high current pulses switched and transmitted between a pulse forming network and a pulse transformer.  Also disclosed is a fluid-tight dual housing arrangement utilizing a high voltage coaxial connector assembly which includes multiple sliding contacts, between inner and outer conductors of matched individual coaxial transmission lines in each housing, to maintain stress-free electrical connections when large differential longitudinal movements take place between the housings and the accelerator equipment contained therein.
