Abstract: ABSTRACT             The invention concerns the design of an oil containment boom suitable particularly for stowage on a reel.  The boom, in its inflated condition, is of "T" section having double buoyancy chambers (11) and a central skirt member (10).  The boom utilises a tension wire (15) in its lower skirt region and an air pressurising hose (14) in its upper skirt region above the buoyancy chambers (11).  The geometry of the panels making up the chambers is arranged, together with the joints, to give a substantially flat deflated form.  The air pressurising hose and the tension wire are of comparable diameter each being of larger diameter than the maximum thickness of the deflated boom whereby undesirable folding and puckering of the boom material when wound up is accommodated in the lateral space between the hose and the wire.

Abstract: PHASE-LOCKED LOOP LASER GYROSCOPE SYSTEM                 Abstract A very high resolution laser gyroscope system having a phase-locked loop operatively coupled to the output of a laser gyroscope cavity.  A difference frequency signal is formed between two output beams from the gyroscope cavity. The phase of the difference signal is compared with that of a reference clock to produce a signal representative of the phase difference between the reference clock and difference signal. The latter signal is amplified and coupled to a coil which produces a field within a Faraday rotator body disposed in the wave propagation path within the laser gyroscope cavity.  The phase of the difference signal is thus phase-locked to that of the reference clock signal so that the frequency difference between the two beams in the cavity is maintained constant over a wide range of rates of rotation.

Abstract: A STEERABLE OCEAN FLOOR DREDGE VEHICLE     ABSTRACT      A steerable ocean floor dredge vehicle is provided which is of the towed variety, or partially self-propelled.          The vehicle is towed from a surface ship via a rigid length of pipe or tubing, connected to the dredge vehicle via a pivoting joint permitting pivotal movement about two transverse axes and preferably about a third axis, and a telescoping joint for providing movement along the direction of the axis of the towing line.  Pivoting means connect from the sides of the dredge vehicle to the towing pipe at a point between the telescopic joint and the surface.  The pivoting means comprise two flexible cables extending about rollers on the dredge vehicle, or hydraulic piston and cylinder combinations.  In operation, pulling one cable, or pushing on one piston, causes the dredge vehicle to be skewed in a first angular direction relative to the towing pipe; pulling or pushing, respectively, in the opposite direction causes the dredge vehicle to be skewed about in an opposite angular direction relative to the towing pipe, thereby permitting at least a limited movement of the dredge vehicle along the ocean floor in directions transverse to the towing pipe.

Abstract: COMBINED WELL CASING SPIDER AND ELEVATOR                      ABSTRACT OF THE DISCLOSURE      A  combined  well  casing  spider  and  elevator  is formed of a main body including a base wall, a top wall, a pair of lateral walls, a first end wall, and a second end wall, the second end wall having two sections spaced from one another.  The main body has a bowl inner wall tapered to reduce the diameter from the top wall to the bottom wall.  A gate member is pivotally secured to one of the sections of the second end wall and releasably secured to the other of the sections to connect the two sections when in a secured position.  The gate member pivots  laterally when released to permit the lateral entry of a well casing within the area defined by the bowl inner wall.  The gate member has a gate inner wall co-operating with the bowl inner wall to comprise a bowl section.   A circumferential  array of casing gripping slips are arranged in opposing pairs for vertical and radial mounting in surface contact with the bowl inner wall.  The gripping slips form a circular hole within the center thereof to receive a well casing and are vertically movable along the bowl inner wall to effect radial enlargement and contraction of the circular hole formed  thereby  by  upward  and  downward  movement respectively to release and grip the casing.  A cross rod  spans  the  main  body  and  extends  into  bearing journals which are attached to the lateral walls of the main body.  A lever is fixedly attached to the cross rod and  vertically  movable  to  rotate  the  cross rod  in the  bearing  journals.   Two  crank  arms  are  fixedly attached to the cross rod adjacent either lateral wall and movable with the cross rod to rotate in respective vertical planes.  Two lift arms are pivotably connected at one end to the crank arms and at the other end to the upper end of a diametrically opposed pair of casing gripping slips.  The array of the casing gripping slips comprise four arcuate segments, the pair of slips the one of which is mounted on the gate inner wall being floating segments with the other pair of slips which are connected to the lift arms being driven segments.  A pair of C-shaped members are mounted on the tops of the floating segments and project beyond the edges thereof towards  the tops  of the driven segments.  A pair of arcuate channel members are mounted on the tops of the driven segments and receive the ends of the C-shaped members  so  that  as  the  driven  segments  are  moved vertically, the floating segments also move vertically.

Abstract: DIGITAL CARDIAC PACEMAKER            ABSTRACT           There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of cardiac stimulating pulses. The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sen-sitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate ex-ceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the accept-ance of a programming signal, and means to reset the program acceptance circuit if extraneous signals are detected as pro-gramming signals.  The program signal acceptance circuit per-forms several different checks on the detected programming signal including a parity check, an access code check and de-termining if the proper number of signals were transmitted within a given time.  The timing circuit of the pulse genera-tor includes a crystal clock oscillator and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: Abstract of the Disclosure A method for removing particulate matter from a gas stream by injecting charged particles into the gas stream to form a large charged surface area to induce charges on the entrained particulate matter. The injected material may be an adsorbent or an absorbent and may be reactive with the gases in the gas stream. The charged particles contained in the gas stream together with the injected particles are passed through a porous moving bed of media such as silica rock; as a result of the electrical charge as well as inertial impact forces on the respective particles, the particles become attached to the media which is continously changed after it has captured the fine particulate matter. The media, together with attached sorbent additive and particulate matter, may then be incorporated into a product the manufacture of which generated the particulate matter.
