Patent ES-8306556-A1 (ES)
Title: Solid state telephone line interface circuit with ringing capability
IPC: H04Q3/00
Filed: 1982-07-09
Abstract: A telephone line circuit including a high voltage amplifier feeds the tip and ring lines at its output. This amplifier is fed by a programmable voltage source which includes a d.c./d.c. converter and means to control the amplitude and polarity of this voltage. All the required electrical signals including d.c. feeding, speech, unsymmetrical ringing and metering pulses are provided through the high voltage amplifier. No high voltage AC switches (relay contacts) are required since the ring signal is provided through the same device (output amplifier) as the speech and d.c. signals. Means are included for minimizing the internal power dissipation by controlling the amplitude of the d.c./d.c. converter voltage. Thus d.c. offset control is achieved by slaving the d.c./d.c. converter voltage to the amplifier output voltage. Three functional blocks form the line interface circuit according to the invention, these being a high voltage circuit including the aforementioned amplifier, a programmable signal generator which includes the d.c./d.c. converter and electronic solid state switching under control of a line feed and supervision circuit which constitutes the third block.

A compression element (54) is adjustable to vary the rate of the spring without alteration of the limit stop position to which the components are urged by the spring load. - The spring volume may be readily adjusted by the compression element after removal of a plug (44). The element is displaceable to increase or decrease the volume by a screwed member (49) rotatable by a tool inserted into a slot (52). Telescopic movement is limited by upper and lower engagement of a flange (1A).  (15pp Dwg.No.1/24) USAB- US4680876 A The article of footwear has a ground-engaging part comprising upper and lower components. A limit stop is associated with the components to define limit stop positions between which the components are capable of limited movement toward and away from one another. There is a spring medium between the components and a compression element movable w.r.t. to one of the components independently of the limit stop. - An adjustable part is rotatable but not axially displaceable w.r.t. to the one component. The adjustable member is operatively connected to the compression element so that rotation of the adjustable member displaces the compression element toward or away from the component. This varies the rate of the spring medium without altering the limit stop positions between which the components are relatively movable by, or against the action of, the spring medium.
