Abstract: An electron source is disclosed for generating a flow of electrons of substantially narrow energy distribution. Such a source may be incorporated into a cathode ray tube (CRT) where the beam of narrow energy electrons is modulated, as by a grid or other target element of the CRT; the current control characteristics of the CRT are dependent upon the energy distribution of the electron beam, and as the width of this distribution in the beam or flow of electrons is decreased, the sensitivity of the CRT is increased. In accordance with the teachings of this invention, the electron beam source includes a mirror element for critically absorbing incident electrons whose energy is above a predetermined value. Electrons whose energy is below the critical predetermined value are reflected from the mirror element to form an electron flow of a substantially uniform energy level.

Abstract: In a video terminal system wherein a number of characters are to be displayed on each forward horizontal scan, a scan control circuit is utilized to synchronize the displaying of characters with the scanning of the cathode ray tube. Both the scan control circuit and the displaying characters are tied to a timing chain. Since the displaying of characters occurs at a fixed predetermined time in the timing chain, the scan control circuit is required to control the movement of the scan such that the phase of the scan is regulated in time. The scan control circuit accomplishes synchronization by a self-regulating feedback circuit which controls the magnitude of the base drive to a power transistor. Since the storage time of a power transistor is proportional to the magnitude of the base drive current to the power transistor, a simplified circuit results which accurately places the characters at a fixed position.

Abstract: A pre-wash stripper composition for use in the water-washable inspection penetrant process consisting of water saturated with dissolved penetrant. The saturated solution cannot dissolve more penetrant, and is therefore incapable of causing depletion of crack entrapments, but when applied to test surfaces by spray, it is capable of removing surface penetrant from test parts to completion of the so-called incubation of washing, and for purposes of recovery of excess surface penetrant for re-use. Test parts which have been pre-washed with the inhibited saturated solution may be finish-washed in clean water with a minimum amount of penetrant carry-over into the finish-wash water.

Abstract: This invention relates to the reproduction of all the essential moisture sorption characteristics of dead wildland fuels through use of an inorganic fuel moisture analog sensor. This inorganic fuel moisture analog sensor is calibrated to and reproduces all of the essential moisture sorption characteristics of dead wildland fuels without being subject to any of the undesirable characteristics associated with wood sensors. This analog is keyed to selectable response timelags, the size of these dead fuels, their water sorption processes, their radiation characteristics, and their thermal properties. This analog is fabricated from activated aluminum as the active material with calcium aluminate as the bonding agent.
