Abstract: Abstract of the Disclosure In a torque sensor of a noncontact type for sensing a rotary torque applied to a shaft, a magnetic ribbon of a film shape formed of a magnetic material and applied in advance with an induced magnetic anisotropy in the direction of an angle .theta. along the circumference of a shaft is bonded to the shaft along its circumference.  A U-shaped first core member having end faces opposite to the ribbons is provided in the vicinity of the shaft.  An exciting coil for producing a magnetic flux and a detecting coil are wound around the core member, and the magnetic flux produced by the exciting coil and introduced through the ribbon to the core member is detected by the detecting coil.  When an exciting current of a predetermined frequency is supplied from an oscillator to the exciting coil to produce a magnetic flux, an output signal is generated from the detecting coil and is measured by a voltmeter.

Abstract: ABSTRACT     An improved method and apparatus for filtration includes an outer stationary body, an inner rotating body defining a gap with the outer body for receiving a fluid sample, the surface of one of the bodies defining the gap being a filter.  The rotation of the inner body creates Taylor vortices which continuously displace occluded solute on the filter surface.  The filter can be a membrane.  The rotational speed and/or a driving force across the membrane may be varied to control the composition of the permeate.

Abstract: ABSTRACT :          "Interpolating filter arrangement with irrational ratio between the input and the output sampling frequencies".     Interpolating time-discrete filter arrangement for increasing the sampling frequency of a time-discrete signal from fi to fu, fu not being a rational multiple of fi. For the generation of the required filter coeffi-cients this filter arrangement comprises clock pulse gene-rators which produce input clock pulses ki(q) at a rate fi and output clock pulses ku(n) at a rate fu. It also comprises a coefficients generator in which a deviation component d(q) is calculated which indicates the relation-ship between the time interval Td(q) located between an input clock pulse ki(q) and the immediately preceding or the immediately subsequent output clock pulse ku(n) and the time interval Tu=1/fu between two consecutive output clock pulses ku(n). In response to this deviation compo-nent the filter coefficients generator produces W filter coefficients, the wth filter coefficient (w = 0, 1, 2, 3, ... W-1) being equal to a(d(q),w) and being defined by the expression a(d(q),w) = h(d(q)Tu + wTu) Herein the function h(v) represents the impulse response of a FIR filter and v a continuous variable in the inter-val -  ?  < v <  ?  .

Abstract: METHODS OF RECOVERING           A CONSTITUENT OF A PROCESS EFFLUENT            Abstract This invention is a process of recovering a constituent of a process effluent, such as an effluent of a process for making a preform from which an optical fiber is drawn.  The effluent is directed into a scrubber (40) of a loop (20) where it is treated with an aqueous solution to provide a solvent mixture which comprises particulates and a solvent solution including the constituent, e.g., germanium.  Subsequently, the solvent mixture is moved into a first filter system (55) which provides a filtrate free of particulates above a first size that is returned to the scrubber for reuse and a residue.  Then the residue from the first filter system is moved into a second filter system (80) which provides a filtrate free of particulates larger than a second size that is smaller than the first size and a residue.  The filtrate from the second filter system also is returned to the scrubber for reuse while the residue from the second filter system is recirculated therethrough.  When the constituent, e.g., germanium, concentration reaches a predetermined level, portions of the residue from the second filter system are withdrawn and subsequently treated with a precipitating agent to recover the constituent, e.g., germanium.  (FIG. 1).

Abstract: ABSTRACT OF THE DISCLOSURE   Items such as components, assemblies, or fully assembled items of equipment (printers, computers, recorders, etc.) may be subjected to burn-in or other test procedures while in storage in a storage and retrieval system which utilizes rack type storage locations and a stacker-retriever vehicle (with shuttle table assembly) for placing item carriers at selected ones of the storage locations.  The item carrier includes means to mount the item and to connect the item to power and control inputs; as well as a power and control input connector connectable to a power and control input connector located at each of a number of test locations within the rack storage area.        The shuttle table assembly in one embodiment, following placement of the item carrier in the test storage location, is raised up to engage the face of the item carrier and to move the item carrier so as to mate the item carrier power and control input connector with the connector of the storage test location.  When the shuttle table assembly is operated to retrieve the item carrier it is first inserted into contact with an item carrier disconnect device and operates same to move the item carrier so as to effect disconnection of the mating connectors.  Thereafter the shuttle assembly is operated to retrieve the item carrier. In another embodiment the shuttle table assembly is formed with upturned lips; the first to move the item carrier deeper into the test storage location to mate the connectors, and the second to coact with the item carrier to effect disconnection of the connectors prior to retrieval of the item carrier.  Remote and local computers and other controls are provided for the vehicle, the shuttle assembly and to provide power and control inputs and effect the test procedure for the item while in storage.  In another alternate embodiment the power and input signal connectors take the form of transmission devices, that merely need to be positioned in proximity to each other and substantial alignment so that the signals from the test location transmission device can be received by the transmission device on the item carrier.

Abstract: ABSTRACT OF THE DISCLOSURE SEPARATION OF COMPONENTS OF A FLUID MIXTURE     A separator comprises a vessel having an outer wall (2) and an end wall (3).  A body (14) adjacent the end wall (3) defines with the end wall (3) an annular opening (15).  In use, a mixture of, for example water and solid material is introduced into the vessel through a first inlet (4). A circulating motion takes place in the vessel and the solid material falls to the end wall (3) and is removed through the opening (15) to an outlet (6) while clean water flows from the top of the vessel through an outlet (8).  In order to increase the energy in the lower region of the vessel so as to assist removal of the solid material, water from the outlet (8) is passed through a pump (P) and reintroduc-ed as energising fluid to the vessel through a recircu-lating port (44).  Energising fluid may be taken from sources other than the outlet (8).  Various alternative forms of separator are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to a well logging method which is capable of providing an indication of salinity and water fraction of the production fluid of a borehole.  This indication of borehole parameters may be obtained through the use of a conventional gamma ray logging system that detects gamma rays produced by isotopes created from neutron activation of oxygen, sodium, and chlorine that may be present in the production fluid.  A logging sonde is passed twice through a portion of interest in the borehole at two different logging speeds.  The fluid velocity relative to the sonde may be determined using these two logging speeds and a displacement distance which reflects the time required for a detector associated with the sonde to reach fluid activated by neutrons produced by the sonde.  From these measurements and knowledge of the flow cross-section and parameters of the sonde, the fraction of water in the production fluid and the salinity of the water may be determined for each portion of interest of the borehole.
