Filed: 1987-03-04
Abstract: New and improved automatic dilution apparatus and method are provided, and are operable in conjunction with automated sample liquid analysis systems to automatically dilute sample liquids as supplied thereby to automated sample liquid analysis apparatus. One embodiment of the dilution apparatus operates to dilute the sample liquids by flowing the sample liquids from the analysis system sample liquid supply conduit, diluting the same, and returning the diluted sample liquids to the supply conduit for flow therethrough to the sample analysis apparatus for sample liquid analysis. Flow of undiluted sample liquids through the supply conduit is prevented attendant operation of the dilution apparatus. A second embodiment of the dilution apparatus operates to remove predetermined volumes of the sample liquids from the supply conduit, and to replace the same with like volumes of a diluent liquid; thereby diluting the sample liquids in the supply conduit for continued flow to the sample liquid analysis apparatus. Both embodiments of the dilution apparatus are operable on demand; and the second apparatus embodiment is additionally operable to dilute the sample liquids to a varying degree throughout a predetermined dilution range.

Abstract: A locating system employs a single-point device employing unique scanning patterns for generating peak signal data which can be used to calculate the position of a signal source (12,14) within a scanned region. One preferred embodiment utilizes a satellite (10) in high earth geosynchronous orbit and a simultaneous yaw and roll pattern to scan a substantial portion of the earth's surface. The point source being located may be virtually any form of transmitter of radiant energy such as infrared, electromagnetic, light or acoustical energy. The scanning device may also be positioned in a low earth orbit satellite, an aircraft, a missile or a helicopter. The single-point device re-radiates the signal source transmission to a computer command center (16) which correlates single-point device scanning position data with received transmissions to accurately compute the location of the signal source (12,14). Beacons (24) placed at precisely known locations may be used to interpret scan data. The computer triangulates peak signals of multiple roll orbits (74) generated during each yaw orbit (75) of the single-point device to determine the precise location of the source (76). The computer may also search a data base to identify the signal source and provide related information previously stored in the data base. 
     The invention is particularly advantageous for locating stolen vehicles and for finding kidnapped persons. 
     An alternative embodiment employs a peak-detecting ground-based receiver and a satellite or other single-point scanning device which generates and transmits a signal to the receiver indicating the satellite's precise current position in antenna yaw and roll. The ground-based receiver is equipped with a computer for calculating its own position by repeatedly correlating the time of peak signal detection and the yaw and roll data from the received satellite signal. Such an alternative embodiment would enable precise self- position determination without the use of a command center. 
     The term "peak signal detection" also includes averaging first and last signal acquisition, counting and averaging all signal acquisitions and all other techniques for determining the direction of maximum received signal strength.

Abstract: A circuit for removing unwanted temporal portions of a voltage varying signal on the occurrence of a reset signal and for differentiating a resultant corrected signal with respect to a reference voltage, has a switch (SW) responsive to the reset signal applied to a first input. The switch is responsive to the reset signal to divert a second input of the switch to a second output from a first output and thence to return the second input to the first output. 
     An input capacitor (C1) receives the input signal. A first operational amplifier (U1-B) has positive and negative inputs and an output connected to the second input of switch (SW), the positive input being connected to receive a voltage representative of the current through the input capacitor (C1). 
     A storage capacitor (C5) has one side connected to a reference voltage and has its other side in electrical connection to the negative input of the first operational amplifier (U1-B) and the first output of the switch (SW). An inverting amplifier (U2) is connected to receive the second output of the switch (SW). A second operational amplifier (U1-A) receives the corrected signal from the inverting amplifier (U2) and has a negative input which is connected through a first resistor (R3) and through the inverting amplifier (U2) to the second output of the switch (SW). The negative input of the second operational amplifier is also in electrical connection through the first resistor (R3)   with the input capacitor (C1) and with the positive input of the first operational amplifier (U1-B). A positive input of the second operational amplifier is connected to a reference voltage, and provides a differentiated corrected signal at its output which is connected via a feedback resistor (R4) to the negative input.

Abstract: The ejector is suitable for powdered and granular material particles, in particular for powdered coating material for spray- coating objects. It contains a venturi channel (8) and inlets (30) of holes (22) for ejection gas are arranged symmetrically around the venturi channel (8) and open into its lateral wall. The ejection gas produces a suction in the venturi channel (8) which sucks material into the venturi channel (8) where it is conveyed by the ejection gas through the venturi channel. This results in a good ejection efficiency. Abrasion, sintering-on and adhesion of material to the walls of the venturi channel are prevented by the possibility of a simple production of precise cross-sectional sizes and relative positions between the holes (22) and the venturi channel (8). <IMAGE>

Abstract: The present invention relates to a method of producing a superconducting wire capable of obtaining a ceramics superconducting wire having a high critical temperature. 
     Although a ceramics superconductor has been recently developed, problems have occurred in that the workability is remarkably lowered, and the constituent elements other than elements of the groups IIa and IIIa in the periodic table, copper and oxygen, which enter superconducting materials as impurities when sintered, have a bad influence upon superconducting characteristics. 
     The present invention solves the above described problems and provides a method of producing a super­conducting wire with a superconducting layer coated with Cu-Be alloys by coating a ceramics superconduc­  ing material with Cu-Be alloys and then turning into a wire material having an appointed shape by the area-reduction processing followed by sintering said wire material at a temperature range at which the superconducting layer can be formed.

Abstract: A system for switching signals travelling between a first set of multicontact ports (S1) and a second set of multicontact ports (U2), in which the signals at the contacts of each of the first ports (S1) are sampled by a parallel-to-serial multiplexer (M1) to form a corres­ponding single serial multiplexed signal (on 51). Each such serial multiplexed signal is applied to a matrix switch (56) of the type having a switching device at each cross-point, and each of the output signals from the matrix switch is supplied (on 54) to a serial-to-­parallel demultiplexer (DM2). Each such demultiplexer supplies its reconstructed separate parallel signals to its associated port (U2) in the second set of ports. By controlling the conduction status of the switching devices in the matrix, the desired connection of each of the first set of ports to the desired one of the second set of ports is accomplished, with many fewer switching devices than would otherwise be required.
