Patent EP-0053295-A2 (EP)
Inventor: O'CONNOR HENRY MONCRIEFF
IPC: G01N27/90
Filed: 1981-10-30
Abstract: The prior art of multifrequency eddy current instruments has required a band pass filter to separate each individual frequency. The drawback of the above mentioned method is the requirement to change the bandpass filter if the inspection frequency is changed. This invention relates to a design that eliminates the requirement for a bandpass filter. The aggregate of inspection frequencies are applied to linear multipliers which shift the information from one of the inspection frequencies to a base band signal. The information is then separated from the signals of other frequencies with a low pass filter. The advantage is that an inspection frequency may be changed by changing the oscillator frequency only.

Abstract: An apparatus for effecting liquid-liquid contact between an aqueous liquid medium and an organic liquid medium comprises a chamber for holding a body of each of the media having an agitator therein. One or both of the media are supplied to a mixing zone around the agitator. By means of the agitator a dispersion band is formed with a free space above and/or below it which is devoid of baffles. A layer of disengaged lighter medium forms above the dispersion band and a layer of disengaged heavier medium below it, at least one of these layers extending into the or a corresponding free space. Disengaged lighter and/or heavier medium is recovered from the corresponding layer thereof at the same rate that it is supplied to the mixing zone.

Abstract: The invention relates to an apparatus for direct heat exchange and/or mass transfer between a liquid phase and a gas phase. The principal structure includes a feed device for the liquid phase, a receiver for the liquid phase, a device for feeding the gas phase and a plurality of run-off walls which are arranged parallel to one another, forming a flow channel, and are plane in horizontal section. The run-off walls are at least zonally inclined relative to the vertical. The liquid-phase feed device consists of a feed channel which is narrow as compared with the width of the channel walls. This feed channel is located in the region of the centre of the flow channels and runs at right angles to the run-off walls which are deformed at the end of the flow channels into outlet ducts which are narrower than the run-off walls. There are free passages left between the outlet ducts and the liquid-phase jets leaving them and flowing to the receivers. The gas phase can be introduced through the passages into the flow channels in the case of counter-current operation, or taken off from the flow channels in the case of co-current operation. <IMAGE>

Abstract: A method and apparatus are disclosed for providing very precise incremental motion of a numerically controlled machine tool, or other similarly controlled object, along a circularly arced path. For a mutually perpendicular X and Y coordinate system, X and Y indices are determined based on certain prescribed input information related to the parameters of the circular path and the relative rate of motion between the machine tool and the workpiece, and on immediate, continuously recomputed, coordinates of the tool or object. The indices are each scaled by a modulus related to the radius of the arc to generate incremental distances AX and ΔY according to which the next move is to be made. The process is reiterated until the desired circular path is complete. In both method and apparatus, only integer values of ΔX and ΔY are used for implementing each increment of motion. Non-integer values are carried forward to the next iteration of the process to prevent error accumulation.

Abstract: A wing flap assembly, in which each flap (1, 2) has its own suspension and drive mechanism (3-6) and in which two adjacent flaps substantially in line with each other have a part (16) connected for movement with one flap and extending between two abutments (18,19) on the other flap so that, in case of a failure or disturbance in the suspension and drive mechanism of one flap, this flap is limited in movement with respect to the adjacent flap to avoid serious distorsions and other dangerous consequences of such a failure or disturbance. Preferably the part (16) extending between the abutments is a pivoting lever, so connected to one flap that it moves therewith in a plane substantially parallel to the chord plane (8) of the flaps if one flap moves with respect to the other one. Moreover, the abutments (18, 19) have adjacent switches (20, 21), so that the part (16) extending between the abutments contacts one of these switches if one flap moves too far with respect to the other flap, so as to give a warning signal about a disturbance or failure and to stop movement of the driving mechanism for the flaps.

Abstract: In a microcomputer system having a main memory accessed by both a central processor unit (20) and a CRT controller (21), a page register system (30) receives page bits defining both CPU and CRT pages from CPU. The CPU page bits are combined with lower order address bits from CPU for CPU access cycles, and CRT page bits are combined with lower order address bits from CRT controller for CRT access cycles. Both CPU and CRT controller can access any of pages in memory. For compatibility with higher level systems, the CPU may provide addresses in a range outside range of addresses for memory. When a decoder (42) detects such addresses, it directs CPU address bits, corresponding in order to CPU page bits issued by the register system, to address memory.

Abstract: A sonobuoy float canister is releasably latched to a wound cable pack container. The cable is attached at its upper end to the canister and at its lower end to a lower sonobuoy component. A rotor latches the canister and container together in one rotative position so that the cable is not unwound or payed out to provide a first or shallow depth deployment of the lower component. In a second rotative position of the rotor the canister and container are unlatched from one another and the cable is positively restrained after a predetermined partial payout to provide a medium depth deployment of the lower component. In a third rotative position of the rotor the positive restraint of cable payout is removed and the canister and container are unlatched so that the cable is fully payed out to provide for full depth deployment of the underwater component.
