Abstract: ABSTRACT OF THE DISCLOSURE An improved method for laundering fabrics to remove oily soil is disclosed, wherein fabrics are contacted with a washing liquor comprising an aqueous solution of a nonionic surfactant system and other ingredients.  The washing temperature and ingredients of the washing liquor are selected so that washing occurs at a temperature which is substantially above the cloud point of the washing liquor and below the phase coalescence temperature of the washing liquor.  Compositions useful in the practice of this inven-tion are also disclosed, comprising a nonionic surfactant to which is added one or more strong electrolytes.  Such compo-sitions may be diluted with water to form a washing liquor which has cloud point and phase coalescence temperatures which are tailored for washing, within the scope of the present method, at a temperature preferred in the art. Conventional sequestering detergency builders and adjuvants may be added to the compositions as desired to optimize the cleaning result.  The compositions may be formulated to provide a washing liquor pH of less than about 11 without diminishing the cleaning performance of the washing liquor.

Abstract: 48D-267 Can ABSTRACT OF THE DISCLOSURE         A closed-loop drive system for variable speed induction motors for maintaining a constant slip frequency, regardless of motor speed.  A slip frequency oscillator generates a signal having a frequency proportional to the desired slip of the motor and a tachometer generates a signal having a frequency proportional to the actual rotational speed of the motor.  The stator frequency is the sum of the rotor speed and the slip frequency during acceleration and the difference between the rotor speed and the slip frequency during braking.  Exclusive OR gates are used to add the slip frequency signal either to the tachometer signal or to the stator signal, the outputs of the gates being applied to a digital phase detector.  The phase detector drives a voltage controlled oscillator which provides the stator signal.  The output of the voltage controlled oscillator is used to trigger the slip frequency oscillator to prevent overlap of pulses to the digital phase detector.

Abstract: Abstract Automated Method For Cell Volume Determination Fluorescence volume exclusion signals are utilized to evaluate cell volume.  Cells are suspended in a medium which is furnished with a fluorescent dye which neither penetrates nor adheres to the cells. Cells are analyzed by an optical flow cytometer, with illumination which causes the dye medium to fluoresce.  Passage of a cell through the sensing zone therefore reduces the amount of fluorescent medium being illuminated, and proportionally reduces the fluorescence output signal.  Fluorescence volume exclusion pulse height and area are related to cell volume.

Abstract: Abstract Prior art interrupted series type load sensitive hydraulic systems have not had the capability of both providing full speed simultaneous vehicle cornering and implement correction while preventing the same when the implements are operating at a high pressure level, and preventing low torque motor stall. Herein, an input flow path delivers pressurized fluid flow from a source to a first priority (steering) circuit.  A series flow path delivers the output flow from the circuit to an implement circuit.  A parallel flow path delivers a portion of the flow from the source to the implement circuit.  A valving structure is in the series flow path.  The valving structure is opened in response to load pressure in the implement circuit being at or below a selected value and is closed in response to the load pressure in the implement circuit being above said value.  Generally, flow through the parallel flow path is blocked when differential pressure in the steering circuit is below a specified value.  High speed turning and implement correction are provided at low pressures and are prevented when the implement is operating at high pressure level.  Low torque motor stall is prevented.  Utilization of vehicle horsepower is enhanced with the selectable series/parallel circuitry.

Abstract: Abstract Method and apparatus are disclosed for creating optical displays from a real optical scene with an optical feedback circuit projecting a parameter of the original scene for combination with the original scene itself or an image thereof.  The feedback circuit may influence the parametric image in many ways to influence the combined optical display.  For instance, the parametric image may be a negative of the real scene to produce a null combined display showing motion where the parametric image is time delayed or the parametric image may be defocused to produce a combined display with edge enhancement.  The feedback circuit may project a vertical parametric image to create fixed relation combined displays or the feedback circuit can project real parametric images continuously to create a combined display which changes progressively as a function of the relation between original and parametric images.  The method and apparatus may be used for a variety of purposes such as motion detection in security devices or live sperm counting or real image enhancement in biological microscopy.

Abstract: ABSTRACT:      In known volume control circuits the overall gain of a low-frequency amplifier is generally varied in that the gain in the negative-feedback branch is varied At very high gain, at which very large output signals are obtained, the negative-feedback is then very small, which may lead to a non-linear distortion.  In accordance with the present invention the gain, suitably of the frequency-compensation stage, is therefore varied so that it increases when the overall gain increases.  The loop gain at higher output amplitudes is then higher than without this step, so that non-linear distortion is reduced.

Abstract: METHOD AND APPARATUS FOR MONITORING AND CONTROLLING A RESISTANCE WELDING OPERATION          ABSTRACT OF THE DISCLOSURE           A resistance welding controller for dynamically controlling both weld current and weld time in order to achieve a desired .DELTA.R value.  The resistance across the weld electrodes is monitored by the controller during the heat-up phase of the weld and compared to target values for minimum resistance (Rmin) and rate of resistance change (dR/dt).  If the observed values for Rmin and dR/dt bear a predetermined relationship to the target values, a dynamic correction is made in the percentage heat control setting.  The weld is then continued at the revised weld current level until the desired .DELTA.R value is satisfied.  If upon weld termination, the observed weld time is greater than the target weld time, an additional correction in weld current is made in prepara-tion for the next weld.  In addition, the controller is also adapted to detect newly dressed weld electrodes and automatically respond by reverting to the original weld schedule.

Abstract: The present invention relates to a method of produc-ing an interwoven seam interconnecting two portions of a woven structure, especially for the purpose of making an endless woven band for use, for instance, in the paper-making industry.  The invention is further related to an apparatus for performing the above-mentioned method.         Up to now, the production of such interwoven seams . was accomplished exclusively manually in such a manner that the ends to be interconnected were frayed, that is, the transversely extending or web weft threads were removed therefrom, to the depth of about 100 to 200 millimeters and over the entire width of the web, and then the weft threads of the one end portion were woven into the other end portion at the warp threads thereof Inasmuch as the distance between the individual threads is t in many instances, very small, many times smaller than 100 micrometers, the manual weaving of the seam threads is a very laborious and time-consuming operation.  It is especially difficult for the seam weaver to make sure that the next thread gripped by him or her is indeed the thread which comes next in the order of the threads of the respective array.  Thread by thread, he or she must make sure that indeed the correct thread of the respective array has been taken out of this array.          Should it, for instance, happen that the thread which should have waited for its turn one more time is mistakenly taken out of the respective array and interwoven with the threads of the other array instead of the next thread of the first-mentioned array, there is obtained a so-called crossing fault which makes the entire woven structure worthless and which must he removed in a laborious repair operation.  Experience with this manual seam weaving operation has shown that many manhours are lost in
