Title: A:D voltage conversion using integrator and comparator - avoids large inputs drift by storage feedback loop between comparator output and integrator input
IPC: H03K7/08
Filed: 1971-07-30
Abstract: The A/D converter avoids drift even with large amplitude input voltages and consists of a comparator and an input reference/signal switch coupled to the input of the integrator. A storage circuit (3, 8, 9) stores the output of the comparator (2), coupled to the integrator output (1) to correct deviations in the output from a given value. The storage circuit input is obtained from a voltage divider at the output of the comparator and is stored at the beginning of the measurement phase. A compensating voltage (Up) can also be applied to the input of the integrator.

The structure corresponds to an elastic textile strand with elastic warp fibres consisting of the highly flexible material and with non-elastic wool fibres interwoven with them. In the structure only the wool fibres are coated with a layer contng. the electrically conductive particles. The textile strand is impregnated with a dispersion contng. the electrically conductive particles and a binding agent. The strand is stretched periodically to a certain length until the binding agent has solidified.

Title: Static converter with capacitors - dischargeable at any time in half-wave into DC load at output of half-controlled rectifier
IPC: H02P7/293
Filed: 1972-07-11
Abstract: The static converter has the supply transformer's secondary connected via a half-controlled rectifier bridge to the inductive load (e.g. motor). A first capacitor (C1) is connected in series with a first charging diode (D1) across the secondary. A second capacitor (C2) is coupled in series with an oppositely poled charging diode (D2) across the secondary. Two discharge thyristors (Th1, Th2) each connect one capacitor to one d.c. pole of the load. Several capacitors, diodes and discharging thyristors can be used. The capacitors may be electrolytic. The advantage lies in being able to pass the energy stored by the capacitors to the d.c. load circuit at any time and thereby improve the power factor.

IPC: G11B5/588
Filed: 1994-09-22
Abstract: A ground compatible voltage-mode instrumentation amplifier comprises an output difference stage (3) and an input buffer stage (2) which comprises two input operational amplifiers (OPIA) and (OPIB). To avoid the operational amplifiers (OPIA) and (OPIB) driving to ground due to loading of the difference stage (3) the internal circuitry of the operational amplifiers (OPIA) and (OPIB) are implemented with respective voltage level shift diodes (S) which are disposed in series with a constant current source (Iss) and a MOSFET MI, the gate of which forms the positive input (1,3) of the respective operational amplifiers (OPIA) and (OPIB). The constant current sources (Iss), the voltage level shift diodes (S) and the MOSFETS MI and M2 of the operational amplifiers (OPIA) and (OPIB) are matched so that the voltage level shift (vs) of the input operational amplifiers (OPIA) and (OPIB) are identical, thereby providing an output voltage (Vc) provided by the function.

Abstract: The invention relates to a contact arrangement for an electrical switch apparatus with at least one fixed contact, shaped like a U with limbs of unequal length, the longer limb, provided with a mounting hole, being used for the current connection and the shorter limb, on the side facing away from the longer limb, being used as the contact. An arc runner is provided adjacent to the contact point and is electrically connected to the contact. The longer limb is pushed from the side into slots in an insulating part which can be connected to the housing, the end part of the longer limb covering the limb of the U-shaped, bent arc runner which is inserted in a cut-out in the insulating part, transversely with respect to the direction in which the longer limb is pushed in. This limb of the arc runner carries the thread for the screw connection. This arrangement results in a simple mounting method for the fixed contact. It is advantageous for prefabrication if the insulating part carries the fixed contacts of all poles of the switch apparatus. <IMAGE>

Patent JP-H0337772-B2 (JP)
IPC: H03G3/20
Filed: 1986-02-28
Abstract: Voice information are converted into pulse code modulated data sequences which, after a further processing, can likewise be deposited in a memory for a specific subscriber. This subscriber can then fetch the information from the memory at any desired time. Given an attenuation of the analog voice signals on the transmission path, a regulation is undertaken in such a manner, given a downward transgression of a mean voice level, that the digital pulse code modulated data sequence is correspondingly modified in its values thus represented, being modified on the basis of a gain factor which can be read from a table. The drive information for the stored table are supplied by a peak value memory which is, in turn, charged with the output signals of an averaging filter. This method therefore provides that the influence of an attenuation of the analog voice signals existing on the transmission path is significantly limited.

Abstract: A multilayer pipe, in particular for brake lines of motor vehicles, is proposed, and also a process for producing such pipes. The multilayer pipe is produced from flat steel strip (1) by winding or round deformation and subsequent soldering by means of a solder layer (2) applied to at least one side of the steel strip (1). In order to avoid leaks and later corrosive effects as far as possible during the production of the multilayer pipe, the solder layer (2) consists of a copper alloy having a melting temperature below 1020 DEG C, preferably below 1000 DEG C. In the process for producing the multilayer pipe, the steel strip is, after electrolytic degreasing, first pretreated in a nickel flash bath or in a copper pickle. The steel strip is then coated with the copper alloy which may contain proportions of tin, zinc or silver for reducing the melting point. After the winding or round deformation has been carried out, the multilayer pipe can be coated with an additional corrosion-inhibiting layer. <IMAGE>
