Title: Accurate positioning of characters in photographic  page composition
Inventor: MOYROUD LOUIS M
IPC: B41B15/00
Filed: 1981-07-20
Granted: 1982-08-03
Abstract: ABSTRACT OF THE DISCLOSURE The machine preferably has a character matrix comprising a rotating drum with character-bearing film strips wrapped around it   The machine has a light source comprising a plurality of flash lamps and fiber-optic light-pipes. The light-pipes are arranged in a linear array aligned parallel to the direction of travel of the film strips on the drum.  Photographic film is formed into a semi-cylindrical arc and remains stationary during composition of up to a full newspaper page of text before the film is moved to another exposure position. Both character spacing and line spacing are performed by a combination of selective timing of the operation of the flash lamps, a lens and reflector traveling parallel to the film in a beam of collimated light, and a swinging mirror mounted on the axis of the semi-cylinder formed by the film.  Both timing slits and base line reference marks are located on the film strips near each character.  The base line reference marks are detected and used to make automatic corrections of the character image locations to ensure excellent base-alignment of the characters on the film.  Other corrections of the charac-ter image locations are stored in a memory and are made automatically during composition.  Several steps are taken to ensure accurate character spacing.  A separate, independent timing circuit is used to time the flashing of each character.  Also, the timing is determined by reference only to the timing slit immediately next to the character to be flashed.  Furthermore, timing delay is controlled by a clock pulse source whose frequency is controlled by the drum rotation so as to compensate for instantaneous variations in drum speed and/ or position.  Each film strip bears coded indicia indicating the illumination level required for each different type face on the strip.  Automatic adjustments are made to compensate for the divergence of the collimated light towards the end of very long lines of type composition.  Special means are provided to compensate for the extension of italics and slanted characters to one side or the other of the normal character area.  Means also are provided for the insertion of "Pi" characters and forming rules.

Abstract: PORTABLE KEYBOARD OPERATED TELECOMMUNICATIONS SYSTEM     ABSTRACT     A portable handheld battery operated telecommunica-tions terminal (10) is acoustically coupled to a telephone-hand set for the transmission and reception of alpha-numeric information over ordinary telephone lines.  A standard typewriter ASCII keyboard (34) enables the encoding of messages for transmission on a character by character basis (Baudot code) or the entire message to a second communications terminal (10) with the same transmission protocol.  A visual display (32) provides a display of data for editing the encoded message prior to transmission and for display of a message received from a second communications terminal (10).  A micro-processor (50) is programmed by processor instructions stored in EPROMs (66) and (68) for controlling operation of the communications terminal (10) from entries from the keyboard (34).  A transmit audio transducer (76) and receive audio transducer (84) transmit and receive audio tones over ordinary telephone lines in the frequency shift key transmission mode in response to pulses from the programmed microprocessor (50).  Random access memory means (62) and (64) enable the user to store an entire message for editing prior to transmission, to enter blocks of alphanumeric information for subsequent transmission, and means for storing a received message for redisplay of the message in the visual display (32).

Title: Ribbon break detector for printers

Abstract: RIBBON BREAK DETECTOR FOR PRINTERS              Abstract of the Disclosure A ribbon feed failure in a printer can cause serious problems, particularly for a printer that uses heat to cause selective ink transfers.  Localized heat buildup may injure the printhead and, if allowed to continue, might injure other printer instrumentalities.    According to the invention, it is recognized that for ribbons having a degree of electrical conductivity, a mechanical ribbon failure will almost always result in a detectable change of electrical properties.  By monitoring the characteristics of an electrical circuit passing through a section of the ribbon around the print point and, preferably, also the printhead-ribbon interface, abnormal electrical parameter values that indicate ribbon failure may be detected to trigger a cessation of printer operation.            For a presently preferred implementation in a printer that uses a printhead with multiple electrodes for supplying current to a ribbon, the electrode voltage levels for a plurality of non-adjacent electrodes are combined to provide a resultant voltage level that is examined to detect abnormalities.  By so combining voltages, insignificant excursions in electrical characteristics as might result from minor ribbon imperfections are generally eliminated from the triggering of a shutdown response, while still retaining a rapid response for preventing further heat generation in those situations where a serious ribbon failure has occurred.

Abstract: Abstract:    Apparatus for controlling high voltage by absorption of capacitive vars, comprising a stator having a core and a three phase winding connected to the high voltage, and a rotor having magnetic material exhibiting a sharp magnetic saturation.  The rotor includes longitudinally extending damper bars inbedded in grooves or slots in a manner similar to the bars used in a squirrel cage rotor.  The magnetic structure of the rotor can be of two types - a symmetrical structure for asynchronous operation, and a salient pole structure for synchronous operation.  In the case of the symmetrical rotor construction, the stator and rotor constitute a rotating induction reactor which operates in the same manner as a free running, unloaded induction motor.  The induction reactor exhibits characteristics similar to a saturable reactor with respect to var versus voltage absorption, but does not have the undesirable harmonics normally present in the saturable reactor.  In the case of the salient pole rotor construction the stator and rotor constitute a rotating synchronous reactor which operates in the same manner as a free running unloaded reluctance motor.  A series compensation arrangement can be provided by connecting capacitance means in series with the stator winding to reduce the droop characteristic of the incremental saturated inductance of the reactor to almost zero.  The transformer connecting the rotating reactor to the high voltage system can be provided with amps for steady state adjustment of the voltage level to be controlled.

Abstract: ABSTRACT Disclosed is a high performance dual-band antenna system which, utilizing a frequency selective reflector surface, renders the antenna ele-vation and azimuth angles variable with a simple construction and without imposing any limitation on the settings of communication equipment and, also, insures desirable cross polarization performance and a minimum of loss.  The system comprises a dual reflector antenna rotatable around elevation and azimuth axes, having a main reflector and a subreflector.  First and second horns radiate first and second electromagnetic waves of first and second fre-quency bands, respectively.  A beam waveguide comprises first and second plane mirrors and first and second concave mirrors, for guiding the first and second electromagnetic waves to the dual reflector antenna by way of the first plane mirror.  The first and second concave mirrors, the second plane mirror and the beam waveguide are rotatable around the elevation and azimuth axes.  A frequency selective reflector surface is provided separately from the beam waveguide means for passing the first electromagnetic wave and reflecting the second electromagnetic wave to feed them to the first plane mirror.  The first and second electromagnetic waves radiated from the first and second horns are directly fed to the frequency selective reflector surface and both the first and second electromagnetic waves provided from the frequency selective reflector surface are fed to the first plane mirror by way of third and fourth concave mirrors.
