Abstract: BACKGROUND OF THE INVENTION     1.  Field of the Invention:       The present invention relates to apparatus and methods for displaying three dimensional graphic information, and more particularly, to data processing apparatus and methods for generating or manipulating three dimensional images on a display system.   2.  Art Background:       In the computing industry, it is quite common to represent and convey information to a user through graphic representations.          These representations may take a variety of forms, such as for example, alpha-numeric characters, Cartesian or other coordinate graphs, as well as three-dimensional shapes of well known physical objects.  For example, in computer aided design (CAD) systems, three dimensional objects may be modeled, reconfigured, and assembled on a two-dimensional cathode-ray tube (CRT) display to assist design engineers in their tasks.  However, in displaying three-dimensional objects on a two-dimensional display, the computer system generating the display must be able to include perspective in the images to add dimension. Moreover, in the case where solid three dimensional objects are to be depicted, some mechanism must be utilized such that hidden surfaces are recognized and portions of the image appropriately eliminated, to obtain the desired three dimensional effect.       One common method for eliminating hidden surfaces in computer graphic images involves the use of a Z-buffer.  In practice, a Z-buffer is a large memory implemented typically with dynamic random access memory (D-RAM) integrated circuits.  A          Z-buffer is generally organized into a linear array, wherein

Abstract: Abstract of the Disclosure A method and apparatus for electrically heat welding a ther-moplastic fitting having an electric resistance heating element disposed therein whereby a regulated quantity of electric power is supplied to the heating element during the welding process and the making of a high quality weld is insured.  In accordance with the method, a controlled electric power is supplied to the resis-tance heating element of the fitting.  The initial magnitude of the current flowing through the heating element is sensed and compared with predetermined current levels for various sizes of fittings whereby the size of the fitting as well as the total time the controlled electric power should be supplied to the heating element of the fitting for the making of a high quality weld are determined.   The magnitude of the current flowing through the heating element over the time the controlled electric power is supplied thereto is sensed at predetermined time inter-vals and compared with predetermined current levels for the size of fitting being welded to thereby determine if the welding pro-cess is proceeding abnormally at such time intervals.  The elec-tric power supplied to the heating element is terminated when it is determined that the welding process is proceeding abnormally or otherwise at the end of the total time determined to be required for the making of a high quality weld.

Abstract: PM9  WIDE FREQUENCY RANGE, SWITCHED-BAND OSCILLATOR                  Abstract A wide frequency range, switched-band, output signal from an oscillator is obtained by dividing the overall oscillator bandwidth into two bands having an overlapping band of frequencies.  An input signal that triggers the oscillator also is supplied to a frequency to voltage converter.  The magnitude of its output signal is compared to a reference signal in a comparator, and a control signal having a certain characteristic is derived when the input signal is in the high band of frequencies.  When the input signal is in the low band, the control signal has a characteristic that is different from the first-mentioned characteristic.  Switching takes place in the overlapping band of frequencies.  The control signal is applied to a switching device that adds or removes impedance, e.g., capacitance from the capacitive part of the, for example, resistive-capacitive, frequency-determining network of the oscillator depending upon the characteristic of the control signal.

Abstract: ULTRASONIC SPRAY NOZZLE AND METHOD                     J. Michael Soth and James R. Klemm Abstract Of The Disclosure An ultrasonic spray nozzle includes a piezoelectric transducer which develops mechanical vibrations in response to an applied periodic electrical potential.  The vibrations are mechanically amplified and propagate to an atomizing surface over which fluid to be atomized is discharged by an internal fluid passage.  Maximum vibrational amplitude of the atomizing surface is achieved when the frequency of the applied electrical potential equals the natural resonant frequency of the nozzle.  A parameter of the applied electrical potential, such as fequency, is periodically varied such that the vibrational amplitude of the atomizing surface is periodically increased and decreased.  Fluid atomization is reduced during periods of reduced vibrational amplitude permitting fluid to be distributed with greater uniformity onto the atomizing surface.  Such uniform distribution results in a significant improvement in the definition of the spray pattern produced by the nozzle during periods of increased vibrational amplitude.  To further enhance uniform fluid distribution, auxiliary fluid passages are provided through the atomizing surface.

Abstract: ABSTRACT OF THE DISCLOSURE    According to the invention, there is provided a so-called picture-in-picture type television receiver in which a sub-picture screen is displayed within a main picture screen in a picture-in-picture fashion.  When a picture based on a base band video signal from an external source such as a VTR, for example, is displayed on the sub-picture screen, if the sub-picture channel selecting means is then operated, the picture of a broadcast television channel is then automatically displayed on the sub-picture screen.  This feature allows the omission of a video signal source switching means for the sub-picture, thus protecting the viewer from being confused when using the controls of the television receiver.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention is directed to an apparatus for handling articles, namely a package loader, comprising trays and a means for supporting trays.  In a preferred embodiment, the trays are relatively flexible cookie trays which are supported on a rotat-able mount.  The cookie trays which are rotatably mounted may be mounted on a carousel-type of support, which automatically rotates and which can be automatically loaded and unloaded.  The cookie trays are not solidly supported, but rather are supported along portions beneath, and in between, regions where cookies are to be received.  As the trays are relatively flexible, it is important that, for soft cookies, no rigid or hard surface be encountered during the relatively high speed loading operation.

Abstract: A mixing tank (1) for the continuous mixing of ferrous sulphate granulate with water. The mixing tank (1) comprises two parallel plastic pipes (2', 2'') positioned helically on the bottom (3) of the tank (1), the upper sides of said pipes having the same water discharge outlet area per area unit of the bottom (3) of the tank (1). As a result, water is always distributed evenly for percolation through the ferrous sulphate solution, thus always producing a ferrous sulphate solution of a "saturated" concentration. The manufacture of the mixing tank (1) is therefore considerably quicker and cheaper than the manufacture of known types of mixing tanks, said mixing tank also being more economical in operation and smaller in dimension than known types of mixing tanks having the same output.

Abstract: The method comprises contacting a suspension of viable lymphocytes with a solution containing a membrane potential sensitive fluorescent dye. The contact between the lymphocyte suspension and the MPS dye is maintained for sufficient time to permit labelling of the lymphocytes by the MPS dye material. The labelled lymphocytes are passed individually through a focused source of excitation energy causing any MPS dye material to fluoresce. The fluorescent emission from each cell is recorded as a pulse, and the number of pulses of each intensity is recorded. The distribution of the number of pulses versus the fluorescence intensity is bimodal. The first peak includes pulses of low fluorescence intensity, and the second peak comprises pulses of high fluorescence intensity. The ratio of the total counts of low fluorescence intensity to the total counts of high fluorescence intensity produces a factor which distinguishes lymphocytes derived from a body afflicted with malignancy from bodies which are not afflicted with malignancy.
