Abstract: DIGITAL FLASH INTENSITY CONTROL SYSTEM FOR PHOTOTYPESETTERS     ABSTRACT OF THE DISCLOSURE      For variable letter sizes being pnotographically recorded in a second generation phototypesetter, it is desired to in-crease generated quantities of light flux produced by the flash lamp operating in conjunction with a font disc where larger letter sizes are thereby imaged upon the photosensitive medium, and conversely, to reduce such flux where smaller characters are to be projected.  The disclosed system employs a digital letter size code for controlling the amount of charge inserted into a storage capacitor via a digital to analog converter and multi-vibrator.  When the flash lamp is triggered at the appropriate time to selectively illuminate a given character, the energy associated with the stored charge is employed to energize the lamp.

Abstract: ABSTRACT OF THE DISCLOSURE A vacuum interrupter having a current interrupting rating exceeding 20,000 amperes r.m.s. comprises an evacuated envelope and first and second disc-shaped contacts within the envelope.  The en-velope comprises a metal housing having a generally cylindrical portion surrounding said contacts and electrically connected to said first contact.  The space between said cylindrical portion and said second contact is so small that during the interruption of currents above 20,000 amperes r.m.s., 25% or more of the arcing current frequently will flow between said housing and said second contact and bypass said first contact.  Arc-removing means associated with the second contact causes any arc between the outer peri-phery of the second contact and the cylindrical housing portion to revolve about the second contact.           An electric bus located near the envelope is normally electrically connected to said first contact to carry current that flown between the con-tacts.  Means located outside the evacuated envelope provides an electrical connection between the bus and the metal housing that is capable during inter-ruption of carrying without damage the full rated interrupting current of the interrupter.  The first contact is a movable contact mounted on a contact rod that is sealed to the housing by a flexible metal bellows located within the housing

Title: Method of taking a pole of a high-voltage d-c  transmission station out of service
Inventor: HAUSLER MICHAEL
IPC: H02J3/36
Filed: 1978-03-20
Granted: 1981-12-22
Abstract: Abstract of the Disclosure:          In conventional devices, a three-phase power circuit breaker is used as the residual-current switch for disconnecting the faulty pole and grounding.  However, this has limitations because of the fact that no inductences to speak of or chokes be present in the ground line.  Therefore in order to provide a simple and inexpensive method of taking an HVDCTS pole out of service without an expensive HVDC breaker, the station pole is grounded through a pole grounding switch which is spaced from the station center grounding electrode, and subsequently a partial fault current of other poles, occurring from the pole being taken out of service, is commutated into the station center groundîng electrode by the residual-current switch in the form of a circuit breaker.  The method of taking a pole of high-voltage d-c transmission system (HVDCTS) out of service, includes a device having a rectifier station connected to a first three-phase network and an inverter station connected to a second three-phase network, two d-c lines connected from one station to the other, each station being divided into halves, the station halves of each station being connected together on one side to a station center grounding electrode, the other side of each station being connectible to the positive d-c line so as to form a positive pole, and to the negative d-c line so as to form a negative pole, and residual-current switching means for taking a pole out of service.  The invention also includes closing a pole grounding switch and opening a residual-current switch in another station, after the pole grounding switch is closed and the resi-dual current switch is opened in the station ot be taken out of service, and thereafter opening a disconnecting switch to switch off the d-c circuit associated with this pole.
