Granted: 1982-08-10
Abstract: SEGMENTED HOLLOW CATHODE LASER DEVICE     ABSTRACT OF THE DISCLOSURE          A laser device for generating multiline emissions when ap-propriately energized. The device consists of two major components, an anode-cathode assembly and, in a first embodiment, an adjustable brewster end section or in a second embodiment, an integral mirror end section.          The anode-cathode assembly comprises one center located short cylin-drical anode and two segmented cylindrical hollow cathodes located sym-metrically on each side of the anode. The anode and cathode are electrically insulated by a cylindrical metal ceramic seal. The outer surface of the cathode is covered with quartz insulating sleeves to prevent electrical discharge from the outer cathode surface and to encourage effective inner cathode discharge. The cathode is thermally connected to the ex-ternal environment through a structure coupled to the cathode and the laser tube envelope thus allowing heat generated within the cathode due to the electrical discharge to be effectively conducted away thereby allowing higher input power load into the cathode for selected lasing action which requires a relatively high excitation input. A metal vapor reservoir may be provided and is preferably attached to the anode section for metal vapor laser operation. While the controlled amount of the metal vapor is released into the anode section, it is transported through each cathode section by natural diffusion and cataphoretic action which provides near uniform vapor density throughout the cathode sections. The laser device of the present invention can be made up of one or more anode-cathode assemblies depending on the laser medium and the selected output requirement.

Abstract: ABSTRACT      An improved exhaust gas sensor of the type having first and second titania ceramic elements which have electrical resistances varying as a function of both the temperature and the composition of exhaust gases from internal combustion engines to which the elements are exposed.  The first and second titania elements are connected in series circuit in the utilization of the sensor and the resistance of the second element over the operating temperature range of the exhaust gas sensor compensates the signal of the first titania element in a manner that produces a desired signal.  The desired signal is a result of variation of the second titania element resistance values when exhaust gases cycle between lean-mixture and rich-mxiture compositions.  The resistance values of the second titania element are intermediate the corresponding resistances of the first titania element over the temperature range.       The second titania element is more dense than the first titania element.  It has a density in the range from 3.2 g/cm3 to 3.8 g/cm3, i.e., between about 76% and 90% of theoretical density.

Title: Digital variable voltage level control circuit  with automatic return to neutral
Inventor: HARSHBERGER ROBERT P JR
IPC: G05B19/07
Filed: 1980-04-09
Granted: 1982-07-06
Abstract: ABSTRACT OF THE DISCLOSURE          A control circuit generates a variable analog output voltage in response to momentary closure of touch control means by an operator.  The control level selected via the touch control means is sampled, digitized, digitally stored and reconverted to the analog output voltage for driving a motor at a commensurate speed. Selection of a different control level generates a correspondingly different digital value and thus a different analog output voltage.  The selected control level and the corresponding analog output voltage may be maintained for an extended period of time until a new selection is made, or a different operating mode is entered.  A mode change causes an automatic reset to a neutral operating condition (e.g., zero analog output voltage).

Abstract: ABSTRACT OF THE DISCLOSURE         A system for processing discrete digitized samples representing composite signals utilizing a filter which eliminates a periodic signal component from the composite signal.  The filter receives and stores consecutive digital sample representations of the composite signal and, for each received sample representation, provides a digital average representation of the values of a selected number of the received digital sample represen-tations which define a zero average value of the periodic signal component.  In one embodiment of the signal processing system, the filter is arranged in circuit with digital delays and digital signal combining and differencing circuits to form a digital color television signal dropout compensator, which is adaptable for use in NTSC, PAL, PAL-M, or other television standard systems.  In a dropout compensator adapted for NTSC color television signals, the filler receives the digital composite television signal and eliminates the chrominance component therefrom, leaving only the luminance component at its output.  A following digital subtractor is coupled to subtract the luminance component provided by the filter from the received digital composite television signal and provide the chrominance component at its output.  The separated chrominance component is phase adjusted on consecutive television lines and recombined with the separated luminance component provided by the filter for substitution in the tele-vision signal in place of the dropout affected portion thereof.  The dropout compensator also includes a digital delay of one horizontal line period through which the television signal components are passed to provide the delay necessary for substituting television signal information from a prior horizontal line.

Abstract: Abstract of the Disclosure Low molecular weight addition copolymers, of (1) (meth) acrylic acid esters of alcohols such as methanol and butanol with (2) esters of alcohols such as N-(.beta.-hydroxyethyl) oxazulidine and unsturated acids such as a (meth)acrylic acid, and (3) optional ?,.beta.-ethylenically unsaturated monomers such as a (meth) acrylic acid, are found to be exceptional dispersants for inorganic and organic pigments and colorants which are insoluble in organic solvents, for lacquers, and in compatibility with practically all types of lacquer resins such as vinyls, nitrocellulose, and alkyds, and with many other types of lacquer film-forming materials.  Usually, when small amounts of unsaturated carboxylic acids, or other polar monomers and combinations therof, are incorporated in the polymers, they become improved pigment dispersants. Such pigment dispersions, unexpectedly, can be let down with many types of synthetic resins and used by air-drying or baking the coated articles. Lacquers for metals, paints and printing inks are examples of uses for such blends.

Abstract: ABSTRACT OF THE DISCLOSURE An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip, preferably made of stainless steel, which is bent into a generally "3" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a hook-shaped end hooked with a locking-member retaining nose on a slider's neck.  The base is normally urged against the spindle of the pull tab by the resilience of the strip.  The hook-shaped end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from being unhooked from the nose.  Thus the locking member is held in position on a slider body solely by the resilience of the strip, requiring no bending or deforming of any part of the slider body that would make the slider defective from an aesthetic view.
