Patent DE-3315156-A1 (DE)
Title: Process for the production of optical waveguides
Inventor: SCHMID KARIN
IPC: C03B37/018
Filed: 1983-04-27
Abstract: In the production of preforms for optical waveguides (optical fibres) by the process, in which a substrate tube is coated on the inside and collapsed, the collapsing operation can be accelerated if a relatively thin substrate tube is used. In order nevertheless to achieve an adequate preform thickness, the invention proposes melting a tube onto the rod produced by collapsing, so that the material of the original substrate tube is thickened. Since silica glass can only be sealed onto silica glass with great difficulty, the interior surface of the tube to be sealed-on is preferably coated with a silica glass material of low softening point. This internal coating can also be supported or replaced by coating the silica glass rod with a silica glass layer of lower softening point before the tube is sealed on. The invention is generally applicable to the sealing of a tube onto a rod in connection with the production of preforms for optical waveguides, irrespective of the process by which the rod is produced. <IMAGE>

Title: Plant for the biological treatment of waste water
Inventor: FUCHS UWE
IPC: C02F3/28
Filed: 1983-08-02
Abstract: The invention relates to a plant for the biological treatment of waste water having an anaerobic reactor 1 operated under anaerobic conditions to which a waste water feedline 3 is connected in the bottom region and which is provided with an overflow 7 in the top region for treated waste water and a gas discharge line 5 for sewage gas. In order to have as large as possible a fraction of biomass constantly available in the reaction chamber of the anaerobic reactor 1 for the biological degradation processes, it is provided that the anaerobic reactor 1 is designed in a funnel shape by wall surfaces 2 running together downwardly at an incline, as a result of which the turbulence effected by the evolution of the sewage gas formed during the anaerobic degradation processes are greatly weakened by the retardation of the established liquid flow and bubble flow caused by the design. In addition, a gas trapping hood 4 is provided in the top region of the anaerobic reactor 1, which hood is provided at its bottom end with guiding devices 6 extending radially outwards to just before the wall surfaces 2 of the anaerobic reactor. These guiding devices 6 have the effect that, in the solid separation zone formed above the guiding devices 6, only a small amount of outgassing proceeds which only insignificantly influences the settling processes in the solid separation zone and the return of the biomass to the reaction chamber. <IMAGE>

Abstract: The invention relates to a device for cleaning a welding torch, in particular the torch of a welding robot. The cleaning device comprises a rotating hollow-cylindrical tool that can be driven into the gap formed on the welding torch between its contact nozzle and gas nozzle. In order to absorb the reaction forces occurring on the welding torch during the cleaning process and thus to keep the hand or robot mechanism holding the torch free from such reaction forces, and also to be able to execute the cleaning procedure as a tolerance-accurate treatment process excluding contamination or wear of the torch, the cleaning device includes a holding device fixing the welding torch in an axial and rotationally secure manner in coaxial alignment with respect to the tool, and a feed device for introducing, with an adjustable lifting rate, the rotating tool into the fixed welding torch. The functions of feed device and holding device can be controlled in a preset and time-table dependent manner, and can be reversed automatically. The tool is preferably designed as a profiling cutter provided externally and internally with cutting surfaces and thereby being able to treat the outer surface of the contact nozzle and the inner surface of the gas nozzle independently in each case.

Title: Method and device for detecting bubbles in a flowing liquid
Inventor: PRESTELE KARL DIPL PHYS
IPC: A61M5/36
Filed: 1983-09-26
Abstract: The invention relates to a method and to a device for detecting gas bubbles (5) in a slowly flowing liquid (4). Particularly in the field of medical technology, such as, for example, in drug-dosage instruments, it is advisable quantitatively to detect the gas fraction (Vg) which has penetrated into a delivery channel (1) due to disturbances and to compare this with a maximum permissible value. In such dosage instruments, throughputs of about 1-1000  mu l/h are delivered through thin hoses (1). A gas bubble (5) which has penetrated as a rule completely fills the internal diameter of these hoses (1). According to the invention, it is recorded on a measuring section (P1, P2; P3, P4) whether liquid (4) or gas bubbles (5) are flowing past. From the residence time (tg) of the gas bubble (5) in the measuring section (P1, P2; P3, P4) and from the flow velocity (Vg) of the gas bubble (5), a measure of its volume is derived. The gas bubble volumes (p1, p2, p3...) are summated over a preset period (T). According to one embodiment, the sum (Vg) is taken to form a ratio with the total volume (Vges.) which has flowed past the measuring section (P1, P2; P3, P4) within the same period (T). If this ratio exceeds an adjustable critical value, an alarm signal (A) is triggered. <IMAGE>

Patent DE-3411772-A1 (DE)
Title: Drive belt
Inventor: BOLL WOLF DR ING
IPC: F16G1/28
Filed: 1984-03-30
Abstract: The invention relates to a drive belt having an endless belt body which consists of elastomeric material and whose surface opposite the rear surface has projections and depressions which extend in the longitudinal direction of the belt and engage in a mating profile on the circumference of belt pulleys around which the drive belt is looped, and which drive belt is equipped with a reinforcing layer. In the case of a drive belt of this type, it is intended to transmit circumferential forces of the belt pulley more uniformly into the surface of the belt than is the case with conventional drive belts. In addition, the drive belt is intended to be distinguished by particularly good wear resistance in comparison with belt pulleys which are offset in the axial direction with respect to one another. This is achieved in that in each case at least one strand is arranged in the central region of the projections, which strand extends in the belt longitudinal direction, is more resistant to tensile stress and passes on its shear stresses uniformly into the belt projections.

Filed: 1984-10-05
Abstract: A foot support for foot covering, in particular for sports shoes, has a support band device with strap or band parts which extend upwards and at an angle towards the front from the shoe inner sole or from an insole and have at their free band ends fastening means so that they can either be fixed to one another over the central part of the foot or on the other hand fastened and held in the place intended for them by being connected to the relevant surface of a shoe part. The band parts can moreover extend upwards from an approximately central section of the shoe inner sole so that not only the central part of the foot is surrounded by this support band device but that the side parts also of the foot back are equally fixed by the band parts of elastic design, in order thus to guarantee a complete foot back support in addition to a firm surround of the central foot. Lastly, a heel strap can also be connected to the band parts, which extends backwards around the heel and on the whole further improves the support for the foot during use of the shoe.
Patent DE-3437610-A1 (DE)
Title: Measurement method and measurement device for a DC actuator
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M3/10
Filed: 1984-10-13
Abstract: In the case of this measurement method for detecting the load current of a DC actuator, a current measurement resistor (R1) is arranged between a main connection of an electronic switch (S1) and that terminal (2) of a DC voltage source (1) which is also connected to the control device of the actuator. During the ON phases of the electronic switch (S1), the voltage (U2) representing the actual current value is picked off the current measurement resistor (R1) via a second electronic switch (S2), which is controlled in synchronism with the first switch (S1), and said voltage is supplied to the control device. At the same time, a capacitor (C1) is charged to this voltage level (U2). During the OFF phases of the switches (S1, S2), the voltage level (U2), which is stored with the aid of the capacitor (C1) is used for simulation of the load current behaviour in the freewheeling phase. In consequence, a gap in the voltage (U2) representing the actual current value during the OFF phases is prevented. Preferred fields of application of the invention are battery chargers for electric cars and motor controllers. <IMAGE>
