Patent ES-386682-A1 (ES)
Title: Digital filter frequency shift modulator
IPC: H04L27/10
Filed: 1970-12-09
Abstract: A frequency shift transmitter includes a digital filter arranged to operate on the borderline of stability so that it simulates an oscillatory circuit. The filter has a feed-back path in to which one or another multiplier is placed by the digital input signal to cause oscillation at one or the other shift frequency. The transmitter circuit 103 is time-shared among n data sources 101. The binary signals from the sources are multiplexed by scanner 102 which samples each bit several times. Bit samples of one state enable gate 110 and of the other state gate 111, so inserting multiplier 115 or 116 in the filter's feed-back path. The filter operates on 10-bit numbers representing the instantaneous amplitude of an A.C. signal, the numbers relevant to the n data sources circulating in multiplex in the filter. The filter's output is distributed to digital-analogue converters 125 to provide, after filtering, frequency shift signals on lines 105. The filter includes a circuit 121, Fig. 2 (not shown), which inserts numbers in to the filter during starting and subsequently provides amplitude stabilization of the filter output by checking the amplitude and appropriately modifying the number fed back by the multipliers.

Patent ES-423331-A1 (ES)
Title: Method of and apparatus for twisting yarn
IPC: D01H7/86
Filed: 1974-02-16
Abstract: A yarn bobbin or package is rotated at high speed about an axis and the air immediately surrounding the bobbin is confined with an open-ended tube that is rotated with the yarn bobbin and projects beyond the yarn bobbin. This tube forms a vortex of air at its open end which has a velocity which decreases axially away from the package. The yarn is pulled off the bobbin toward this open end and passed through an eye axially spaced from the yarn bobbin so that this yarn is guided through the vortex to form a balloon. The air currents in the vortex brake the thread. The eye can be mounted well above the assembly, or can be provided in a recess in an insert received in the top of the yarn package. Offsetting this eye to the rotation axis of the yarn body causes a tension vibration to be formed in the yarn that prevents the snapping of the yarn during twisting thereof.

Title: Process for the production of textile softeners
IPC: C08G71/00
Filed: 1974-04-10
Abstract: This invention relates to the production of condensation products which can be used to impart a soft handle to textiles. A monobasic fatty acid with at least 8 carbon atoms and/or montanic acids is reacted with dipropylene triamine and/or diethylene triamine.

Title: Thread supply device for textile machine having common thread control and tension sensing element
IPC: B65H63/00
Filed: 1977-02-10
Abstract: A thread supply device for a textile machine, such as a knitting machine, having a drive. The thread supply device includes a thread drum on which a thread issuing from a supply bobbin can be wound tangentially to form an intermediate thread supply and from which the thread can be removed over a removal edge of the drum. A thread-control element is positioned adjacent to the path of thread removal in the vicinity of the removal edge, and against which the thread abuts laterally due to the tension of removal during a positive thread supply mode. The thread-control element also functions as a thread tension-sensing element and is movable responsive to a decrease in the tension of the removed thread such that, when this tension falls below a predetermined value, this element activates a switching structure which stops the machine drive.
