Patent SE-8000627-L (SE)
Inventor: LIBBY D R
IPC: B01D11/04
Filed: 1980-01-28
Abstract: A liquid-liquid solvent extraction system comprises a mixing stage which includes a mixing device (10) for creating a dispersion of the two liquid phases followed by a residence chamber (14) designed to enhance contacting and mass transfer between the solute and solvent phases. The separating stage includes a drop size conditioning device (15) which establishes a drop size in the discontinuous liquid phase of the dispersion which can be easily separated from the continuous liquid phase in the succeeding settling device (16). The conditioning device (15) also acts to reduce entrainment of the solvent phase in the solute phase during separation of the phases. The settling device (16) may contain a series of baffles to reduce the time required for phase separation and to reduce entrainment of the solvent phase in the solute phase. 
<??>The system is used to extract metal ions such as uranium, copper, cobalt, nickel, and vanadium from aqueous process streams containing dilute concentrations of such ions. Hydrocarbon solvents which are partially or totally immiscible in water are used to extract the metal ions and may contain additives such as complexforming agents to aid in the mass transfer of metal ions to the solvent phase. After contacting and separation of the phases, the metal ions are recovered from the hydrocarbon solvent.

Abstract: An aircraft instrument for warning the pilot that the aircraft is in an unsafe condition in proximity to the ground. The instrument has inputs representing aircraft configuration, flight condition with respect to the ground, and glide slope. Detector circuits process the inputs and give a warning of unsafe proximity to the ground. The boundary conditions for the warning are selected to avoid false warnings. A glide slope detector distinguishes between a valid glide slope signal and spurious signals, without need for pilot input.

Abstract: A process for producing a stretched multilayer polyester bottle which comprises axially stretching a bottomed multilayer preform comprised of an inside and an outside polyester surface layer and an interlayer of a gas-barrier resin provided therebetween optionally through an adhesive under conditions which induce molecular orientation of the polyester and simultaneously stretching it circumferentially by blowing. The multilayer preform is produced by coating a solution or emulsion of an ethylene-vinyl alcohol copolymer on one surface of a primary preform of the polyester molded in advance, drying the coated preform at a temperature at which no whitening owing to the crystallization of the polyester occurs to thereby form a thin but continuous film of the ethylene-vinyl alcohol polymer on the primary preform, mounting the coated pre-form on an injection mold, and injection the polyester onto the coated layer to form the inside or outside surface layer of the polyester. This process enables the ethylene-vinyl alcohol copolymer to be interposed as the interlayer of the stretched polyester bottle in a thickness which does not hamper the stretching operation but is sufficient to ensure its gas-barrier property.

If any of the centers are night service-connected or out of operation for some reason, a call from a subscriber will be automatically re-routed to another center. When a subscriber equipment unit (SE) associated with a subscriber (TA) has called the telephone number of a duty center (A), the call is answered automatically by an automatic telephone answerer (ATS) or by other equipment which can execute a call diverter function. Instead of a spoken message, there is recorded on the automatic telephone answerer a signal which enables receiving a new telephone number in the subscriber unit (SE), which number is recorded on the telephone answerer. The telephone number message can be accompanied by a single which causes the subscriber unit to disconnect the established telephone connection, or this can be achieved by a caller's time monitoring facility's disconnecting when criterion acknowledgement signal has not been received. After a suitable time lag, the calling sequence is started once again, but to the supervision center (C) intended by the received telephone number.

Abstract: The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs clamped at one end in an approximately cylindrical socket body, formed by a thin-walled deformable sleeve. After introduction of the straight contact springs into the socket body from one socket end, they are made fast by deformation of the socket material and their free ends are brought into supporting abutment on an annulus. This is associated with a mandrel for assisting assembly, which passes through it and which is during manufacture introduced co-axially into the socket body and finally withdrawn from it. Subsequently the mandrel together with the annulus is introduced into the socket body. The contact springs are then, by applying axial pressure on their ends, converted into a shape bowed into the interior of the socket until they abut the mandrel. Thereafter, the mandrel is withdrawn from the socket body with relaxation of the permanently deformed contact springs and the annulus is held fast in its position in the socket body by folding over of the socket body edge.

Abstract: PURPOSE:To decrease the effect of the jitters of a tone signal by making a frequency changing point into a reference for a frequency measuring time, preventing a part near the changing point of the tone signal from being measured, and averaging the signal by means of the counted value of the input signal. CONSTITUTION:A gate signal generator 1 controls the gates of counters 4 and 5 to compare an input signal at every cycle. A counter 2 measures how many cycles of the input signals 11 are inputted in the counting period of a counter 6. The time to measure the tone signal is decided with the changing point of the frequencies as the reference, the measurement of the tone signal is started when the tone signal is stabilized from the changing point of the frequencies, and the signal is measured up to the next changing point of the tone frequencies. Further a function to cancel the jitters of the input frequencies is added to a circuit to search for the frequency changing point. In addition, the measurement of the tone signal is averaged by the counted values of the input signal and a reference clock, and thus the measured value is obtained. Thus the effect of the jitters of the tone signal can be decreased.
