Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is an improvement in the man-ufacture of sintered nickel plaque electrode material by a method which comprises blending together, either in the dry or wet state, nickel metal powder and one or more binders, then coating or doctoring the resulting blend on a current collector, such as an iron or nickel grid, and sintering the composite to reduce the blend to a porous nickel plaque adhering strongly to the current collector.  The improvement comprises adding a selected pore-forming material to the blend before coating ox doctoring the blend onto the current collector.  The pore former is a material that is selected from the group consisting of nickel oxide, nickel carbonate, nickel hydroxide, nickel oxalate and mixtures thereof, with the first three named materials being preferred.  The most preferred species is nickel oxide.  The pore former can be added to the blend in any suitable concentra-tion, for example 1 percent or more, with concentrations as high as 30 or 40 weight percent being effective to increase the por-osity of the finished plaque material substantially over that of nickel plaque formed without using the pore former.  The pore former is converted during the sintering operation to pure nickel but in the process results in the formation. of the desired in-creased concentration of voids in the plaque. The pore formers utilized in accordance with the improvements of the present method are inexpensive, readily available and highly effective.

Abstract: CIRCUIT FOR NOISE REDUCTION PARTICULARLY USEFUL WITH       SIGNAL RECORDING/REPRODUCING APPARATUS     ABSTRACT OF THE DISCLOSURE   A circuit for noise reduction is disclosed, includ-ing a first signal path connected to receive an input signal and including a high pass filter for providing substantial de-emphasis of the lower frequency components of the input signal relative to the higher frequency components thereof and a variable gain amplifier for amplifying the output of the high pass filter with controllable gain.  A second signal path is connected to receive the input signal and provides little or no de-emphasis of the higher frequency components relative to the lower frequency components of the input signal.  The outputs of the first and second signal paths are summed to produce a noise-reduced output signal.  The gain of the variable gain amplifier is controlled so as to exhibit higher gain when the input signal level is relatively low and to exhibit lower gain when the input signal level is relatively high.  This circuit can be used for level-compression, as in a noise-reducing encoder for a signal recorder, and may be used for signal expansion as in a noise-reducing decoder for a signal reproducer.    -i-

Abstract: INDUSTRIAL CONTROL SYSTEM                 ABSTRACT OF THE DISCLOSURE         A control system for controlling an industrial process includes a plurality of remotely located process control units (remotes) each coupled to an associated input/output device(s) and adapted to communicate with one another through a dual channel communications link.  The system permits each of the remotes to assume supervisory control of the communications link on a master-for-the-moment basis with the remotes communicating with each other over the communications link by simultaneously sending redundant blocks of information over each of the dual channels of the communications link.  The receiving remote tests the validity of the received messages by first selecting one of the two channels and providing an acknowledgement (ACK) if the received information on the first-selected channel is valid.  If the information on the first-selected channel is invalid, the receiving remote then selects and tests the validity of the information on the other  alternate channel.          If the information received on the other, alternate channel is valid, an acknowledgement is sent to the transmitting remote, and, if the information received on both channels is invalid, a non-acknowledgement (NAK) is sent to the transmitting remote to request retransmission of the in-validly received information.  Other features include performing the information validity check on alternate channels of the communications link with each successive trans-mission of information, providing redundant remotes for detecting the failure of one of the controlling remotes and for assuming control responsibility thereover; observing the status of the controlled devices and recording changes in that status along with the pertinent time-of-day information; and detecting an open or degraded portion in either of the dual channels of the communications link and inserting a line terminating impedance on either side of the open or degraded portion of the channel.

Abstract: METAL VAPOR LAMP HAVING INTERNAL MEANS   PROMOTING CONDENSATE FILM FORMATION                       ABSTRACT   In a high intensity metal halide discharge lamp, means are provided associated with the interior surface of the envelope to promote thy formation and spreading of a liquid film of condensate thereon.  Such a film can lower the color temperature as a result of pressure broadening and self-reversal of the sodium line, and also by acting as a color correcting filter.  The film-promoting means may be a coating which imparts an ir-regularity to the surface such that the reduction in exposed surface area by coverage with a uniform liquid film is energetically favored.  Alternatively, a chemi-cally different surface better wetted by the metal halide dose may be used.

Abstract: INDUSTRIAL PROCESS CONTROL SYSTEM                     ABSTRACT OF THE DISCLOSURE           An industrial process control system in accordance with the present invention includes a plurality of device controllers connected together through a common buss with each device controller connected to an associated controlled device(s) that effect process control.  A computer-aided system interface for controlling the overall system includes a visual display device in the form of a multi-color CRT and a graphic input device in the form of a transparent touch-responsive panel that overlies the CRT display screen.  Computer generated symbols representing the controlled devices are displayed on the CRT screen to define touch-responsive target areas. When an appropriate target area is touched by a human operator, a signal, such as a command signal, is generated to cause the controlled device whose symbol is displayed in the designated target area to respond, with this response being then indicated by a change in the device symbol being displayed on the screen.  Other features include generation of a "hit" display to indicate the last coordinates on the display screen touched by the operator, a two-step execute command sequence for entering high priority commands into the system, and the changing of analog set point values as a function of the time that a selected target area is touched.  The system advantageously eliminates some, if not all, input through a conventional keyboard so that the system operator interfaces with the system through easily comprehended and non-ambiguous visual symbols.
