Abstract: DIGITAL SPEED CONTROL SYSTEM  ABSTRACT OF THE DISCLOSURE   A speed control for controlling the speed of drive motors in a multi-stand mill where a master control remotely located with respect to the stands provides signals representing the desired speed of the drive motor for each stand and these signals are carried to the respective stands over a bus conductor or cable.  At each stand a signal representing actual speed and the respective signal representing desired speed are compared and the resulting difference signal applied to a speed regulator which regulates the motor speed towards the desired speed.  In the past an interruption in the master control, or an incorrect signal, or an interruption in the bus conductor could shut down the mill.  The control system described has at each stand a validity check and a memory.  The master control periodically provides desired speed signals which up-date the respective memory and the up-dated signal in the memory is used to provide desired speed information.  If the master control is temporarily interrupted, or the bus conductor fails, the mill will continue to run based on the last stored signal in the memory representing desired speed until such time as the particular process in the mill requires a speed reference change.

Abstract: ABSTRACT:       Arrangement for biasing high-frequency active components, more specifically field effect transistors, in the form of a power supply circuit intended to apply a direct biasing current to a high-frequency active component which is arranged in series with the main transmission line via a transmission line section pro-vided between the circuit and a main transmission line and which has in the junction where it is connected to the main transmission line an impedance which is suffici-ently high to prevent the useful high-frequency signal flowing in the main line from being conveyed to the power supply circuit while allowing the transmission of the direct current produced by the circuit. The arrange-ment comprises a filter, which is a bandpass filter with respect to the useful high-frequency signal and is formed by two conductive strips which are arranged in parallel with the main transmission line, symmetrically on both sides of the junction between the line section and the main line. These strips are situated at a dis-tance from the junction equal to approximately one-eighth wavelength of the useful high-frequency signal.         Used for biasing all types of high-frequency active components and more specifically components in systems for receiving television signals transmitted by satellites.

Abstract: Abstract of the disclosure:         .omega.-Fluorosulfatoperfluoroalkanoic acid derivatives of the formula VII                 FSO2-O-CF2-Rf-COY            (VII) in which Rf is a single bond or an unbranched or branched perfluoroalkylene radical preferably containing 1 - 10, and especially 2 - 8, C atoms, and Y is F or OR (R is an alkyl radical preferably containing 1 - 10 C atoms, in particular CH3 or C2H5), are prepared starting From .alpha.,.omega.-bis-fluorosulfatoperfluoroalkanes of the formula VIII                FSO2-O-CF2-Rf-CF2-O-SO2F      (VIII) in which Rf has the same meaning as in formula VII.         The compounds of the formula VII in which Y is F are obtained by the decomposition of the starting com-pounds VIII in the presence of catalytic amounts of at least one alkali metal fluoride and/or alkali metal hydro-gen fluoride at temperatures between about -30 and +150°C, with continuous removal of the compounds VII in which Y is F formed in this reaction.        The compounds of the formula VII in which Y is OR are obtained by reacting the starting compounds VIII with catalytic to approximately equimolar quantities of at least one alkali metal fluoride and/or alkali metal hydro-gen fluoride, and in the presence of an at least approxi-mately equimolar amount of an alcohol of the formula IX     in which R has the meaning mentioned for formula VII, and, if appropriate, also in the presence of an inert diluent which does not dissolve the alkali metal fluorides and/or alkali Metal hydrogen fluorides, until an amount of sul-furyl fluoride which is approximately equimolar in rela-tion to the amount of the starting compound VIII has been liberated.       The compounds VII are valuable intermediate pro-ducts, in particular for the preparation of perfluorina-ted vinyl ethers which still contain an ester group at the other end of the molecule; these are in turn important monomers for copolymerization with tetrafluoroethylene and other fluoroolefines for the purpose of producing ion-selective membranes, cation exchange compositions and fluorocarbon elastomers.

Abstract: Capacitor Discharge Ignition System Having A Charging Control Means Abstract The invention provides charging control circuitry (20) for capacitor discharge ignition system (10) having power capacitors (21) connected to be discharged by main electronic switches such as SCR's (23) into ignition transformers (24) to sequentially fire the engine's spark plugs (16).  The charging control circuits (20) each include a charging SCR (26) to limit charging current flow to the main capacitor (21), unless a discharge pulse into the ignition transformer (24) has occurred in the recent past.  Thus if a short circuit in either the main capacitor (21) or main SCR (23) in one of the ignition circuits (19) prevents that ignition circuit from properly functioning, the charging SCR (26) will limit the flow of charging current to the defective circuit and allow the other ig-nition circuit (19) to receive charging current. The gate of the charging SCR (26) is controlled by an amplified signal from a memory capacitor (28) which is charged by the discharge pulse from he corresponding ignition circuit (19).  The same memory capacitor (28) also provides power to drive an indicator such as a light emitting diode (40).

Abstract: TECHNIQUE FOR MONITORING GALVO ANGLE            ABSTRACT OF THE DISCLOSURE           Disclosed is a radiant energy optoelectronic position monitor system which detects the angular position of a "galvonometer mirror" (beam scanner) used in an optical disk memory arrangement.          Using a single infra-red monitor beam, angular motion is converted to linear displacement of an image on a detector cell so as to produce a corresponding electrical signal.  This signal is presented to a processing circuit with an analog divider to normalize output scale factor.  The result is a high gain electrical circuit for recovering output signals in an environment with strong magnetic interference.          Such a position sensor is described as especially apt for use in a "three beam" laser optical system comprising a writing beam and two reading beams all incident on the same track of a rotating disk optical recording medium.  One of these reading beams is incident on the track ahead of the writing beam so as to serve as a "read-before-write" beam, while the other reading beam is incident on the track behind the recording beam so as to serve as a "read-after-write" beam.

Abstract: Abstract of the Disclosure In a pager receiver of a paging system, a reception controller is kept operable when a switch is closed. A first transistor energizes a receiver part at the beginning of a call code part of a received calling signal. If a calling code for that receiver is detected at a certain call time slot of the call code part, the first transistor maintains energization until the end of that call code part and again energizes the receiver part during a message time slot corresponding to that call time slot in a message code part which next follows that call code part in the received calling signal. A second transistor energizes a display part a little before that message time slot. If a message code is detected at that message time slot, the second transistor maintains energization to generate an alert tone and a visual display. As soon as a blank message pattern is detected at that message time slot) the second transistor suspends the energization. It is preferred that a calling code for any one of pager receivers of the system be placed nearer to the beginning of the call code part and that a blank call pattern be placed in each call time slot where no calling code is present. As soon as the blank call pattern is detected, the first transistor suspends energization without waiting for the call code part end.

Abstract: ABSTRACT      In the machine recognition of hand printed characters it is desirable that the characters be constrained to a uniform size.  This may be accomplished by taking a relatively unconstrained hand printed character and, through simple logical processes involving eliminating and/or combining portions of the unconstrained character, obtain a constrained character of a specified size.  To obtain this specified character, the unconstrained characters are stored in a video line buffer as a plurality of rows of binary bits.  When a row character is located in the video line buffer a process of vertical and horizontal consolidation is initiated.  In the vertical consolidation, which is performed first, predetermined rows of the bits of the row character are selectively combined with other rows of stored bits or selected without change to reduce the height of the character to a predetermined desired height.  Unselected rows are ignored.  As the rows of bits are obtained during vertical consolidation, horizontal consolidation of each row is initiated.  This consolidation is performed on a byte by byte basis so that each row is transformed in accordance with a predetermined relationship between the width of the row character and the desired width.
