Abstract: ABSTRACT            The invention relates to sprayer for multifactorial agrochemical interaction tests, used to advantage as a fast, correct and energy-saving solution for experiments conducted with chemical fertilizers and agents, The apparatus has interlocking correspond-ing to the gradient- and wave-functions between the runs corresponding to the course and the agent quantities in proportion to the factors, realized preferably by microprocessor control unit setting the feeders and choke valves. The settings corres-ponding to each factor can be separately adjusted and in the process of spraying the machine treats the adjacent plot units by close ratio- and charge realization, as a result of which cultivation tracks are not necessary, the inter-plot penetra-tions are reduced to miminum and space requirement of the multifactorial experiments is also consi-derably reduced. A special advantage of the appa-ratus is the mechanization and more accurate inter-pretation of the multifactorion experiments, it facilitates the increased and more efficient use of the aerial survey techniques, but it can be used to advantage in confined space or under green-house etc. conditions as well. Since there are no cultivation tracks, the crops - depending on the spraying variations - can be more easily harvested by machine, than those so far, and the plots en-sure the same continuous cultivation surface as the large-scale cultivation. The apparatus is suitable for the easy and fast realization even of 5 - 10 factorial multi-repetitive experiments, thus it allows the experimental optimization of nearly all parameters of the modern complex technologies in a single process.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus comprising a vehicle such as a sledge contain-ing a reel, bin, or the like, holding casing material folded flat, is disposed for travel immediately over an underwater object or piece ground to be covered and is towed by a surface vessel. Situated behind the supply of casing material, rela-tive to the direction of travel, is a table comprising two hinged parts sloping down toward the bottom of the body of water, the lower of the two table parts being arranged to slide over the object or piece of ground to be covered. Con-crete of plastic consistence coming from the surface vessel by means of a pressure hose is injected into the casing sliding over the table, the nozzle of the hose being inserted through an opening between the two edges of the casing material. This opening, which may be formed in a zipper by means of two zipper slides, is then closed by joining the two long edges to form the casing. The movement of the vehicle and the force of gravity cause the filled casing to slide down the table continuously onto the object or piece of ground to be covered. Two lateral arms may be provided for shaping the casing around and under a submerged object such as a pipeline. With this method and apparatus the number of divers needed for laying the covering is substantially reduced.

Abstract: Abstract An inner mandrel extends the full length of the bridge plug, and carries a top sub at its upper end for latching engagement with a conventional overshot to retrieve the plug.          A tubular outer mandrel is slidably mounted on the inner mandrel for limited axial sliding movement.  A partial central bore in the inner mandrel and coacting ports adjacent the upper ends of the two mandrels provide  a valved bypass passage bridging the seal element.  External slips are carried in a slip carrier axially fixed to the inner mandrel by shear screws.  A tubular setting assembly consisting of a lower top wedge for expanding the external slips, an upper compression member, and an annular elastic seal element disposed for compression between the wedge and compression member, is yieldably secured to the outer mandrel by means of shear pins.  Second yieldable shear pins couple the top wedge and compression member.  The outer mandrel and tubular setting assembly  are adapted to be coupled to electric line operated pressure setting apparatus for lowering the tool and for effecting upward pull of the mandrel and downward push of the setting assembly to set the tool.  During the setting, the setting assembly first shears from the mandrel to set the top   wedge and the seal element is then compressed.  A bottom wedge assembly includes a collet wedge releasably coupled to the outer mandrel to be moved into engagement with the external slips, the setting movement of the collet wedge compressing a compression spring.  For release of the bridge plug the coupling between the outer mandrel and collet wedge is released; and upward move-ment of the outer mandrel, provided by coupling to the inner mandrel, effects release of the collet wedges allowing the com-pression spring to retract the collet wedge, and picks up the compression sleeve and the top wedge to release the seal element and the top wedge.

Abstract: ABSTRACT            "Frequency synthesiser".           A frequency synthesiser of the type having a reference frequency source CPG, frequency reduction means PS which cancels pulses from a frequency to be reduced and a jitter compensation signal circuit arranged to compensate for any jitter in the output frequency that would otherwise be caused by each cancelled cycle. The jitter compensation signal is derived from a jitter-containing pulse train via a d.c. removal circuit DCR and an integrator INT. Additionally, a perturbation signal is injected by a control device CD which causes pulses to be added to and also to be subtracted, by PA and PS res-pectively, from the frequency to be reduced, the jitter caused by this addition and subtraction also being com-pensated for by the compensation signal circuit.

Abstract: C A N A D A     TITLE    : CLAMP-ON AMMETER                    INVENTOR : AURELE J. BLAIN     ABSTRACT OF THE DISCLOSURE     The clamp-on ammeter consists of an iron core which extends to form a loop surrounding the conductor to be measured,and a moving coil which is caused to vibrate or rotate is placed in a gap in said core so that the voltage induced in the moving coil, by the flux, will correspond to the current being measured.  For DC measurements an AC voltage is applied to a coil around the core to produce an alternating flux in the core to neutralize errors caused by residual magnetism, in the core.  A means for increasing the range of the clamp-on ammeter consisting of another coil around the core and a current through the coil which produces a flux in the core that cancels the flux produced by the conductor current and the current in the said coil can be applied in various steps so that the meter will have various ranges.  For AC current measurements a coil is wound around the core and the output of said coil is rectified and applied to a reading device,however, due to residual magnetism in the core the output of the coil will be non-linear.  To correct this a capacitor is connected across the coil and the value of the capacitor is large enough to act as almost a short across the coil.  The action of the capacitor causes the output of the coil to appear linear.  Furtermore, the capacitor acts as a low resistance across the coil and a large current flows in the coil and the flux produced by said current tends to cancel the flux produced by the conductor and this greatly increases the meter range.  Furthermore, the non-linearity of the rectifier diode is overcome by means of a transistor.

Abstract: Abstract:          Vibration-compensating  interferometer   mirror   drive system An interferometer mirror drive system compensates for velocity and tilt errors induced by ambient vibra-tion, as well as providing long-term automatic align-ment of the mirrors.  A uniquely configured .lambda./8-thick step on the fixed mirror of the interferometer intro-duces a 90-degree phase shift in one of two reference light  beams,  to  produce  quadrature  signals which characterize the relative motion between the fixed and the driven mirrors.   An  electronic  circuit extracts velocity and tilt data from the quadrature signals and develops error signals indicative of deviations from the  desired  coordinates  of  the  moving  mirror.   The error signals are used to generate a set of control signals which in turn are supplied to an arrangement of drive coils attached to the moving mirror, to re-store the mirror to the desired coordinates.
