Title: Monitoring system for smelt temp. and oven cladding thickness - uses heat conductive body and electrically conductive body for temp. and thickness measurements, respectively
Inventor: LINGORSKI NIKOLA ANGELOV DIPL
IPC: G01B7/06
Filed: 1989-06-13
Abstract: The monitoring system is used for continuous measurement of the temp. of an electrically conductive metal smelt and for discrete measurement of the fire-resistant cladding of the smelting oven, with the temp. measurements obtained simultaneously at several points. The temp. measurements are obtained along 2 accurately defined cross sections of a heat conductive body incorporated in the cladding via thermoelectric sensors lying in each cross section. The cladding thickness measurements are obtained via an electrically conductive body, for closure of a sequence of normally open contacts upon respective wear levels being reached. The output signals from the temp. measuring system are converted into digital signal for subsequent evaluation and those from the thickness measuring device are processed via a logic analyser. USE - For high temp. smelting oven.

Title: Electronic clock generator for vehicle flashing lights - filters out interference from on-board supply to prevent lamp relay switching wrongly due to transients
Inventor: SEILER HARTMUT DIPL PHYS
IPC: B60Q1/38
Filed: 1989-07-12
Abstract: The clock generator (20) has a flip flop (26) controlled by a timing circuit (8, 9) to control a relay (1) in the supply network of the vehicle to switch a load on and off (pref. a flashing lamp (2)).  The current in the relay winding is compared with a threshold for the timing circuit is changeover switch (211) which lies slightly below the armature attraction current of the winding. The time between applying a voltage to the winding and the attainment o the armature attraction current serves as filtering time for suppressing incorrect switching of the relay due to brief supply disturbances. ADVANTAGE - Reliably filters out interference from supply.

Title: Carbon di:oxide returned from bottle filling machine - is restored to useful concn. by controlled injection of pure gas into mixer
Inventor: AHLERS EGON
IPC: B67C3/10
Filed: 1989-09-13
Abstract: In machines for filling drink into bottles, injection of drink is preceded by injection of inert gas, esp. CO2. On insertion of liq., this gas, now mixed with air but still with a high proportion of CO2, is returned for restoration to high CO2 concn. This is delivered into a tube holding a static mixer (16). Downstream of the mixer a probe (21) measures the concn. of CO2, which in an electrical or electronic control unit (22) is compared with a target value. The controller output acts on a valve (19) which from an external source (20) delivers into the supply line, upstream from the static mixer the correct amt. of pure CO2 to achieve the reqd. conc. The pure gas is injected from a feeder (17) coaxial with the mixer. ADVANTAGE - Using a relatively small amt. of pure CO2, total CO2 consumption is reduced, and discharge into environment made more acceptable.

Abstract: 2.1 In known video recorders, a signal reproduced from the magnetic tape is supplied to a television receiver connected to the video recorder either via a radio-frequency modulator and a first output socket for a radio-frequency signal or via a second output socket for a video-frequency signal. A problem occurring in practice consists in that the channel to which the frequency of the said radio-frequency modulator is set can be occupied by a transmitter which leads to moire disturbances in the picture reproduced. For this case, a rotary knob, by means of which the frequency of the radio-frequency modulator can be set to a different channel, is provided at the rear of known video recorders. 2.2 In the new video recorder, the radio-frequency modulator can be disconnected so that, when the television receiver is connected to the video recorder via its second output socket, the occurrence of moire interference caused by the radio-frequency modulator is basically eliminated. 2.3 Video recorders. <IMAGE>

Abstract: In a method for the wet treatment of textile material by the drawing-out process, the textile material (8) in the making-up form is present as a wound body (6) or in a pack system. In this making-up form, it is introduced into a boiler (3) closable in a pressure-tight manner, and then the air is removed at least substantially from the interspaces in the textile material (8). In the course of the method, the liquor present as an aerosol flows through the textile material (8). To reduce the water and energy consumption and to improve the quality of treatment, the textile material (8) is first transferred into a state of increased temperature and low residual moisture. Subsequently or simultaneously, the air is removed at least substantially for the interspaces in the textile material, and after this state has been reached a gaseous medium, which is under an increased pressure and which forms together with the liquor an aerosol, flows directly through the textile material (8). <IMAGE>

Title: Working voltage monitor for selector banks in telephone exchange - assigns comparator to each voltage with outputs switched together for unit able to produce alarm signal
Inventor: FREYE KLAUS-DIETER
IPC: H02H3/20
Filed: 1989-11-29
Abstract: Four comparators (K1,K2,K3,K4) are used to monitor positive working voltages (+U1,+U2,+U3,+U4) and a further four comparators (K5,K6,K7,K8) monitor negative working voltages (-U5,-U6,-U7,-U8). The comparators (K1...K8) compare all working voltages with reference voltages (Ur1,Ur3) that have been derived from a single reference source (REF). Comparator outputs are commoned together and trigger an alarm in the output unit (A) should an over or under voltage condition occur. Low pass filters (TP1...TP8) ar eused on all working voltage inputs to suppress l.f. noise. A coupling network (MKW) is used to maintain a constant comparator hysteresis switching level, independent of the working and supply voltages, when response threshold of the comparators (K1...K8) are set up using the input resistors (R1...R8). USE/ADVANTAGE - Circuit can be easily formed as modules. Comparator response threshold level determined by single input resistor.

A 1 : 1 ratio of the distance measuring range is produced on the length of the photosensitive sensor. ADVANTAGE - Requires no cable connection. Sharp imaging over complete measuring range for accurate evaluation. Resistant to temp. changes.
