Patent EP-0123191-A2 (EP)
Inventor: BAUMGAERTNER ARMIN DR
IPC: C03B37/012
Filed: 1984-04-07
Abstract: A process for the production of glass elements, in particular preforms for optical waveguides, in which a porous element is moulded from a pulverulent glass starting material. The latter is mixed with a liquid or solid aggregate and introduced into a rectangular mould which is rotated about its longitudinal axis during or after the filling operation. A radially varying material composition of the porous element to be moulded can be achieved under the action of centrifugal force. Thereafter, the material in the mould is compacted by compression or without compression, and the aggregate is removed from the compacted porous element by heat treatment and/or chemical reaction before the latter is converted into a glass element by sintering.

Abstract: A laser beam scanning device (17) is provided for monitoring for thread breakage in tufting machines (31) in which a carrier web (16) is passed from below to a spiked roller (11) and is deflected by the spiked roller into a substantially horizontal direction so that it can be passed beneath a row of needles (12). The row of needles (12) periodically introduce threads into the carrier web (16) by up and down movement in order to form tufted material. A narrow retro- reflecting strip (14) is arranged directly below and behind the tips of the needles and directly above the tufted material (15) parallel to the row of needles (12) and substantially at right angles to the surface of the tufted material. The scanned light beam (18) is regularly interrupted by the threads which pass through the needles (13) when the needles are in the elevated open position and, after reflection at the retroreflecting strip (14) and other optical elements is received by a photoelectric receiver (19) where it generates an AC output signal. If one of the threads is broken then the scanning beam (18) is not interrupted at this position and this is recognised in the output signal from the light receiver (19).

Abstract: A circuit for voltage multiplication has a capacitor which is connectible via first switching transistors to a supply voltage source and via further first switching transistors in series with the supply voltage source and with a storage capacitor which is connected in parallel to the circuit output. Clock voltages for driving the first switching transistors are switchable in amplitude from a value corresponding to the supply voltage to the value corresponding to the output voltage. In order to achieve high efficiency of the circuit, a clock voltage generator is controllable for amplitude switch over via a supply line which is connectible via a second switching transistor to the supply voltage source and is connectible via a third switching transistor to the circuit output, whereby these switching transistors are driven via the outputs of the comparator which compares the supply voltage to the output voltage. The circuit may advantageously be employed in hearing aid circuits.

Abstract: An apparatus for shaping a strip, especially a metal strip includes a pair of working rolls which are provided with a plurality of forming tools spaced about the circumference of the rolls. Arranged before the working rolls is a pair of guide rolls which run in synchronism with the strip speed. In order to be able to increase the operating speed of the apparatus, i.e. to allow the working rolls to run at a higher speed than the advance speed of the strip, in between the guide rolls and the working rolls a roller is located which is movable in a direction perpendicular to the advance motion of the strip and is supported by the strip itself and by springs located in respective casing. A compensation between the different speeds of the guide rolls and the working rolls is provided by the gradual depression of the roller by the strip against the force of the spring.

Abstract: In a digital-to-analog converter, a digital input signal of x bits is subjected to digital-to-analog conversion with at least two of x bit positions recognized as a common bit position and converted into analog levels of a number which is different from 2<sup>x</sup> where x is an integer. At least one additional common bit position may be selected from the x bit positions except the common bit position. The digital input signal may be pre-processed by the use of a logic circuit (15) prior to the digital-to-analog conversion so as to control the number of analog levels. The digital-to-analog converter is applicable to a modulator which produces a quadrature amplitude modulated signal having a circular arrangement of signal points on a phase plane. A demodulator comprises an analog-to-digital converter for converting the above-mentioned analog signal into a reproduction of the digital input signal.

Abstract: A pressure stabilization system for a linear compressor piston (24) in which a check valve (68) and passages (72, 64) within the piston permit communication between a compressor work space (26) and a non-working volume of gas (54) through a port (66) in the piston cylinder (30). The check valve (68) and ports allow momentary fluid communication between the dead space volume (54) and the working volume (26), which serves to stabilize working volume pressure and counteract the effects of gas leakage about the piston (24) and into the dead volume (54). This fluid communication only occurs when the dead volume pressure is greater than the working volume pressure and the port (66) and passage (64) are aligned.
