Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus for color and brightness correction for a multi-gun color CRT display, providing compensation for variation in phosphor efficiency with cathode energization and for color tracking between guns.  The brightness correction circuit is required to respond only to essentially DC changes, while a color selection circuit responds at a video rate.  In a preferred digital embodiment, brightness and color tracking correction factors are stored in memory dedicated to a particular CRT, and addressed in response to input from a reference brightness level selected by an operator.  A color selection decoder having stored in a second memory relative brightness characteristics of each color phosphor as a function of the hue commanded converts an input binary command to an analog output, which is combined with the brightness and color tracking correction factor to determine the resulting cathode energization for each color gun.  In an analog embodiment, brightness and tracking corrections are performed by a logarithmic amplifier which applies an appropriate multiplier factor to the reference brightness level.  Color selection is provided by a variable gain amplifier having gain control bias varied by a digital color decoder in proportion to the desired relative brightness levels.  A hybrid system is  also described combining digital memory storage for brightness and tracking correction and an analog variable gain amplifier  for relative brightness compensation, using the circuits described above.

Abstract: ABSTRACT         The controller includes a power sensing device which monitors the instantaneous power drawn by the machine and compares it with a predetermined limit level of desired power consumption.  A user programmable timer is manually accessible for loading a selected time delay period therein.          The controller provides an output capable of altering the machine operation when the machine power consumption has continuously exceeded the limit value for the selected time period.  The controller outputs may be latched or nonlatched once an overlimit condition is detected in accordance with a user selectable programmed parameter.  In an adaptive mode, the controller forces the feed rate to a programmable feed rate for a selected period of time upon initial impact be-tween the workpiece and the machine tool.  The controller then maintains a normal adaptive power level in which the feed rate response may be selectively altered as a percentage of an exponential function of the difference between the actual machine power consumption and the programmable desired adaptive power level.  Provision is made for automatically referencing the feed rate control signal to the voltage rating of the feed rate drive motor in the machine.

Abstract: ABSTRACT        A measuring and dispensing closure for containers of granular material employs a slide element slidable in and out of a container cap top.  The slide element has a chute element positioned thereon defining a series of trap spaces into which granular material is passed from the container when the slide element is in its retracted position.  When the container is turned upside down and the slide element is moved outwardly relative to the cap top, the chute chamber passes out from a discharge opening formed on the cap top to expose the trap spaces to atmosphere for dis-pensing the granular material.  Communication between the interior of the container and the trap spaces during dispensing is prevented by a planar ledge portion formed on the cap top and underlying the space beneath the chute chamber member.  The slide element is preferably formed of plastic molded material and also includes a biasing member to provide a return force against outward movement of the slide.  The series of trap spaces are positioned in sequence so that the user may dispense all or only a portion of the material collected by the chute element, depending upon the amount of outward extension of the slide.

Abstract: LOW VOLTAGE FIELD EMISSION ELECTRON GUN                         ABSTRACT     A field emission electron gun (10) is disclosed which has an extraction electrode, composed of one or more sharply pointed electrode tips (17) in close proximity to a field emission cathode tip (11), such that a relatively low voltage between the cathode tip (11) and the extraction electrode tips (17), in the range of 100 to 2000 volts, will cause field emission of electrons from the cathode tip due to the extremely high localized electric field at the cathode tip.  The electrons in the beam extracted from tile cathode (11) are at a relatively low kinetic energy, particularly adapting the beam for use in such applications as low energy electron microscopy and low energy electron diffraction.  For such applications, the extracted beam is generally passed through a limiting aperture member (21), electrostatic lenses (24, 25), and a deflection coil (26) when scanning of the target (27) is desired.

Abstract: ABSTRACT OF THE DISCLOSURE:         A frame, more particularly for a shower parti-tion, comprising shaped rails connected together at a right angle.  In the case of a frame of this kind, pro-blems arise in the corner area in that the surfaces of the rail, shaping element, covering profile, or the like in that area must be carried over into each other.  More-over, as a result of production inaccuracies, when a frame of this kind is assembled, gaps arise into which dirt can penetrate and which are also constructionally undesirable.        It is therefore proposed that a facing element be provided in the connecting or joint area between the rails on the outside of the frame, the facing element comprising at least one spring locking device.  The locking device engages and/or catches in an opening or recess in one the shaped rails, thus ensuring an easily produced but func-tionally reliable attachment of the facing element to this shaped rail.

Involves measuring the density of a liquid sample in a closed vessel, subjecting this sample to a reduced pressure and thereby expanding the "free" gas in the liquid sample.  After this expansion has taken place, but before allowing dissolved gas to come out of solution, the volume is fixed and a second density measurement is taken.  An apparatus therefo also disclosed.  The apparatus comprises: a chamber wherein a liquid sample is subjected to a reduced pressure and an increased volume, and a means for density measurements of the said liquid sample.  Also disclosed are means to transfer into the chamber a liquid sample while avoiding the entrapment of gas bubbles.  Preferably the chamber has a flexible wall coupled to a suspended weight to enable quick expansion of the chamber while minimizing friction losses and liquid leakage.  Once the "free" gas has expanded, the volume is fixed and a density measurement is taken.
