Title: Digital double differential phase-locked loop
IPC: H03L7/197
Filed: 1977-07-06
Abstract: A first generator provides a reference pulse train having a predetermined reference frequency. A second generator including a voltage controlled oscillator provides a bit clock having a repetition frequency locked to the repetition frequency of the bits of digital data. A first divider coupled to the first generator divides the reference frequency by a selected one of a first division factor and a second division factor different than the first division factor. A fourth divider coupled to the second generator divides the repetition frequency of the bit clock by a selected one of a third division factor and a fourth division factor different than the first, second and third division factors. A phase comparator coupled to the first and second dividers compare the phase of the output signals of the first and second dividers and produces a control signal proportional to the phase difference between the output signals of the first and second dividers. The control signal is coupled through a loop filter to the voltage controlled oscillator to lock the phase of the bit clock to the bits of the digital data. Logic circuitry coupled to the digital data source, the second generator and the first and second dividers produce a phase slip rate signal to select the appropriate one of the first and second division factors for the first divider and to select the appropriate one of the third and fourth division factors for the second divider.

Title: Drive unit for a conveyor chain
IPC: B65G43/02
Filed: 1979-01-10
Abstract: A conveyor chain drive unit having a main frame formed essentially by an H-section structural member whose flanges provide a pair of vertical plates located on either side of the path of travel of the conveyor chain.

Title: Method and apparatus for handling inner and outer box in match machine line
IPC: C06F1/12
Filed: 1979-05-04
Abstract: In a handling system for the inner and outer boxes of matchboxes the long sides of both boxes are aligned transversely to the direction of transport.

Title: Method of determining a value proportional to the length of yarn axially unwound from a bobbin of spun or cross wound yarn and devices for performing the method.
IPC: G01B7/04
Filed: 1980-03-25
Abstract: There is measured the length of a thread withdrawn overhead from a spinning cop or from a yarn bobbin. In order to circumvent the fault sources caused by slip and/or thread elongation there is generated a signal which periodically varies in accordance with the movement of the thread release or detachment point at the spinning cop or at the yarn bobbin, as the case may be, and there are counted the number of cycles of the fundamental frequency of this signal. The thread length is obtained by multiplication of the counted number of cycles by the constant thread length of two successive winding layers for spinning cops or yarn bobbins of the same origin and the same thread. The periodic signal can be derived from the thread withdrawal force or from the number of revolutions of the detachment point. The method is particularly suitable when rewinding a number of spinning cops on to a cross-wound bobbin.
