Abstract: 3.3.78 ABSTRACT:           An electronic transmitter for direct current telegraphy by means of polar line currents comprises a switching circuit for selectively connecting one of the two poles of a telegraphy battery through a unipolar constant current source to a telegraph line, and an output filter having a capacitor in parallel with the telegraph line.            The higher frequencies in the telegraphy signals are sufficiently suppressed to keep the noise level in adjacent telephone lines below a prescribed value because the output filter also comprises two com-plementary branches in parallel with the telegraph line, at least one of the two branches supplying, in response to a polarity transition of the line current supplied by the current source, a correction current pulse hav-ing a polarity opposite to the line current to the tele-graph line.  This output filter is assembled from small-sized, low-priced elements so that an efficient miniatu-risation of the electronic transmitter in its entirety can be realized.

Abstract: Abstract of the Disclosure The invention relates to a process for the preparation of crosslinked polymers by reacting liquid epoxide compounds and polyisocyanates and, if desired, polyhydroxy compounds. The curing catalysts used are complex compounds of BF3 with ethers or phosphonium compounds or H2O.      If desired, a compound of one of the metals Sn, Zn or Fe which is soluble in the reaction mixture is also added.         In most cases it is possible to dispense completely with the external supply of heat when carrying out the process according to the invention, since the reaction is sufficiently exothermic.      The technical advance lies in the fact that it is largely possible to dispense with heating and insulating equipment when carrying out the reaction industrially.      Des-pite this, astonishingly high glass transition temperatures are obtained.

Abstract: ABSTRACT OF THE DISCLOSURE           Ion sources which become coated with insulative materials are rejuvenated by forming the repeller electrode in the ion source of gold and bombarding such repeller electrode with ions to sputter the gold onto the coated surfaces to render the conductive again. Gold sputtering is accomplished by bombarding the gold repeller electrode with inert argon ione.      To perform this method, the slit of the extractor plate in the ion source is greatly reduced in cross-sectional area such that the normally higher sputtering pressures may be maintained within the ion source itself. If a direct sample probe is used, it too may be formed of gold and used to provide the gold sputtering source.

Abstract: ABSTRACT OF THE DISCLOSURE A safety cutter blade assembly for a rotary trimmer is provided herein.  It includes a circular hub formed with a central opening for mounting it on the drive shaft of a rotary trimmer and three blades intergal therewith, and extending outwardly from the hub in equiangularly spaced relation.  Each blade is formed with convex cutting edges, the inner end portion of which is tangential to the hub and a comparatively short straight cutting edge on the side of the blase opposite to that having the curved cutting edge.  Either of these cutting edges is adapted to be effective when it is the leading edge as determined by the direction of rotation of the trimmer drive shaft and the position of the blade assembly relative thereto.  The blade assembly is of rub-ber which may be reinforced by plastic fibers or layers of fabric.  The blade thus has cutting edges in its opposite sides, with one cutting edge being particularly designed to cut long grass or weeds with a negative cutting action which throws the cut foliage outwardly away from the hub and trimmer drive shaft, while the cutter edge on the opposite side of the blade is designed to cut short grass with a positive cutting action.

Abstract: DEVICE FOR AUTOMATIC MODIFICATION OF ROM  CONTENTS BY A SYSTEM SELECTED VARIABLE          Abstract of the Disclosure A device for use with a digital computer for storing standard software used by the computer and modifying the address portions of the standard software prior to transmission to the computer.  The device includes a ROM package containing a ROM within which is stored a standard software subprogram written assuming it is stored at an absolute location in the computer's memory other than its actual location in the computer's memory system.  Also included in the ROM package is a base register which can be loaded, under control of the operating system software, with an offset value reflecting the difference between the actual starting memory system location of the subprogram stored in the ROM and the assumed absolute starting location of the subprogram.  Each ROM cord includes an extra bit to indicate whether the corresponding data word contains an address requiring relocation.  As a word is read out of ROM, a gating circuit tests whether an address relocation is required.  If the test is positive, the gating circuit sates the value in the base register into one input of an adder located on the ROM package, the other input to the adder coming from the data word read out of the ROM.  The resulting modified data word outputted from the adder is sent to the computer.  If the ROM output does not indicate that a relocation is required, the gating circuit provides a zero input to the adder so that the adder output reflects the unmodified input from the ROM.
