Abstract: Abstract of the Disclosure A matrix printer hammer repetition r?te control is disclosed for varying the print hammer repetition rate in accordance with printing speed, thereby maintaining constant width of printed characters without dot column sensing.  A master clock is counted over each character period to generate a digital code which, after conversion to an analog signal, serves as the control voltage for a voltage controlled oscilla-tor.  The VCD output is a variable clock from which the timing for various print heads is derived.  Printing data is gated to the hammer drive circuits at a variable rate proportional to the speed of the printing heads across a printing medium.

Abstract: ABSTRACT OF THE DISCLOSURE               A circuit breaker includes an operating mechanism having powerful mechanism springs to achieve the requisite contact pressures for high current carrying capacity.  A single crank of a rotary handles through a relatively small arc of 120° resets the operating mechanism via a reciprocating slide and a latching mechanism, while loading the mechanism springs.  Return of the handle to its original position shifts the line of action of the springs such as to abruptly straighten toggle and achieve rapid closure of the circuit breaker contacts.  The latching mechanism is equipped with plural circuit breaker tripping capabilities, together with a lockout and bell alarm switch accessory.

Abstract: ABSTRACT OF THE DISCLOSURE           Method of forming a fabric selvedge with two crossing threads and two noncrossing threads in each case.          According to this method, a crossing thread and a non-crossing thread in each case are associated with one another as a pair of selvedge threads and are guided in eyelets situated substantially adjacent one another.  The selvedge is formed by cyclic repetition of the following method steps:  a) shed forming movement of the one pair of selvedge threads in one direction and the other pair of selvedge threads in the other direction, subsequent swinging of each crossing thread from one side of its associated noncrossing thread to the other side and insertion of a weft thread, and b) shed forming movement of the one pair of selvedge threads in the other direction and the other pair of selvedge threads in the one direction and subsequent insertion of a weft thread.  Also, the crossing threads are so guided and swung that at each shed forming movement following the swinging of the crossing threads, the crossing thread of each pair of selvedge threads is crossed over with the noncrossing thread of the other pair of selvedge threads.  There is also disclosed an arrangement for carrying out the aforesaid method.

Abstract: ROTARY FORMING MACHINE AND TOOL           ABSTRACT OF THE DISCLOSURE           A rotary forming machine and a rotary tool utilized therewith for performing a forming operation on a workpiece.  A work spindle rotatably mounts the workpiece about a first axis and a pair of tool spindles which each support a plurality of the tools are rotatably mounted about spaced second axes on opposite sides of the first axis.  Each tool has a partially circular forming face extending about the associated tool spindle axis for an angle less than 180 degress with forming projections that engage the workpiece.  Associated pairs of the tools on the two tool spindles cooperate with each other to simultaneously form the workpiece in an opposed relationship to each other.  Each tool includes a metallic body with a leading end and a trailing end between which its forming face extends as do base and side wall surfaces.  The rotary tools preferably have elongated shapes with maximum heights that are approxi-mately 25 percent of their length.  The tool spindles are mounted for movement toward and away from each other to permit the forming of workpieces of different sizes, while a pair of tension members prevent movement of the tool spindles away from each other.  The forming projections on the rotary tool are disclosed as teeth for providing a splining or gear forming operation.  During forming of a workpiece, a double enveloping worm gear drive train for the tool spindles, a timing gear drive for the work spindle, and a drive control cooperate to provide precise forming.

Abstract: APPARATUS FOR DECTECTION OF SYNCHRONISM BY  MEANS OF VECTOR DIFFERENCE MEASUREMENT            ABSTRACT OF THE DISCLOSURE          Solid state apparatus for the detection of synchronism between line and bus voltages in order to permit safer interconnection therebetween is disclosed. A first comparator circuit constantly monitors the magnitude of the vector difference between the line voltage and the bus voltage and generates a first enabling signal whenever the magnitude of the vector difference voltage is below a predetermined value.  The first enabling signal will continue to be generated until the magnitude of the vector difference voltage rises above the pre-determined value.  A second comparator circuit monitors the relative magnitudes of the line and bus voltages and generates a second enabling signal whenever a high bus-dead line or a dead bus-high line circuit occurs.  The second enabling signal will continue to be generated as long as one of these conditions exist.  The enabling signals are applied to a time delay circuit.  If either enabling signal is applied to the time delay circuit for a pre-determined time period, the time delay circuit will generate an output signal which enables a connection between the bus and line.
