Abstract: METHOD OF CULTURING ANCHORAGE DEPENDENT CELLS            Abstract of the Disclosure Disclosed is a method of growing anchorage-dependent cells:  cells of the type which normally undergo mitosis only when anchored on a substrate, e.g., fibroblasts or epithelial cells.  The method comprises the steps of encapsulating a seed culture of the cells within a semipermeable membrane and suspending the capsules in a growth medium.  The interior sur-faces of the capsule membrane and/or collagen enclosed within the capsules serve as a substrate for the cells.  The ratio of the available substrate surface area to the volume of the culture may be large, thereby allowing the cells to be grown substantially throughout the volume of the culture medium.

Abstract: VIDEO SIGNAL PROCESSING CIRCUIT             ABSTRACT OF THE DISCLOSURE         A processing circuit for a composite color television signal formed of a chrominance component and a luminance component includes a comb filter of the type including a lH delay line.  In order to process the chrominance component, the comb filter is followed by an operational circuit providing a difference signal representing vertical correlation of the input chrominance component for consecutive line intervals, and a feedback loop circuit for combining the input chrominance component with the feedback difference signal before application to the comb filter.  A detecting circuit detects correlation o video information in the luminance component in vertically aligned portions of successive horizontal line intervals, and provides a detecting signal which is used to adjust the feedback loop gain of the feedback loop circuit in accordance with the detecting signal.  The processing circuit can further comprise a luminance comb filter including the delay line and an additive combining circuit, which is followed by a subtractive combining circuit and a band pass filter having an input connected to an output of the subtractive combining circuit and an output connected to an input of the latter.  This circuit gives the luminance comb filter a flat frequency transfer characteristic.  In the detecting circuit, a delay circuit is provided formed of a pre-emphasis circuit, an AM modulator, a delay line, an AGC circuit, an AM detecter, a de-emphasis circuit, and a low pass filter.

Abstract: ABSTRACT OF THE DISCLOSURE       A reversible motor is coupled to the stern leg of a watercraft for angulating the leg up and down through a trim and tilt range.  A manually settable device provides a voltage signal corresponding to the desired trim angle and a position sensor provides a voltage signal corresponding to the present stern leg position.  A first comparator changes the state of its output is the difference between the signals has one polarity and a second comparator changes state for the opposite polarity.  The state changes turn on one of two transistor switches which provide an up or a down signal, respectively, to a motor control circuit for causing the motor to run until the difference is nulled.  When the active transistor switch turns off, the other delivers a momentary pulse for plugging the motor.  The switching transistors are supplied from a power source through up and down tilt control push button switches which, when operated, remove power from the transistor switches and the entire trim control circuit and disable the trim function.  The position signal and another reference signal, corresponding to the upper trim limit, are fed to a third comparator such that if the stern leg is tilted out of the permissible trim range any state changes of the first and second comparators are nullified to thereby disable the trim function.  Other comparators nullify the trim function in response to an electric circuit failure. The trim control remembers where it was set and restores the stern leg to the trim angle existing at the time the tilt function overrode the trim function by disabling the latter.

Abstract: HIGH POWER DIODE LASERS Abstract of the Disclosure A high power diode laser has a double heterostructure epitaxially grown on a channeled substrate.  The substrate has three channels, a central one being shallower than two flanking channels. The heterostructure, in a region extending between the two outer channels is essentially planar except where a first confining layer of the heterostructure is locally thickened owing to the presence of the central channel.  During laser operation, unwanted side bands in the far field light output which are apparent at low power are found to reduce, the laser output concentrating in the desired Gaussian profile at high power.  The laser is superior in this respect to known single and double channeled double heterostructure lasers.                             -i-

Abstract: Abstract of the Disclosure Disclosed is a low toxicity oil for use in drilling fluids.  The oil consists essentially of branched- and cyclic-paraffins having 11 to 17 carbon atoms per molecule and further having a low aromatic content of less than about 1% and a low normal-paraffin content of less than about 5%.  The low polynuclear aromatic oil is useful in both oil-based and water-based drilling mud, particularly where low toxicity and lack of water sheen are important such as in offshore drilling environments.  The oil also has the advantage of being non-fluorescent so that it does not mask UV fluorescence of forma-tion crudes produced from the drill cuttings in wildcatting operations.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a method for separating lysozyme from egg-white which has a lysozyme fraction and an albumin fraction, without destroying the commercial utility of the lysozyme fraction or the albumin fraction.  The method comprises the step of preferentially, reversibly binding the lysozyme fraction of the egg-white to an affinity resin at about the natural pH of the egg-white by contacting the egg-white with the resin, separating the albumin fraction from the resin to leave the lysozyme fraction bound to the resin in a lysozyme-resin complex, and eluting the bound lysozyme from the resin to obtain a lysozyme solution and reusable resin.  The eluted lysozyme and the separated albumin fraction are further treated in separating processing lines to produce a commercial albumin fraction egg-white product and a commercial lysozyme product.          The invention also deals with the preparation and compositions of suitable affinity resins for the reversible, preferential binding of lysozyme in egg white.
