Patent DE-2606452-A1 (DE)
Title: Back-flushing of activated charcoal effluent filter - using water preheated by waste heat from process
Inventor: BORST ADOLF H
IPC: B01D33/00
Filed: 1976-02-18
Abstract: A method of back-washing an activated carbon (activated charcoal) filter in a sewage treatment plant utilises hot water for the back-washing. The water is heated by the waste heat obtd. from the incineration of rubbish or sludge or from engine exhaust gases. After heating, the water is passed through the filter bed to desorb it and is then cooled and returned to the effluent inlet channel. Since, in order to back-flush a filter, it is of advantage to utilise an appreciably higher temp. than during the adsorption onto the filter material, the use of heat which would otherwise be wasted enables the back-flushing to be carried out considerably more economically at an only slightly increased cost.

Title: IC engine with water dissociation apparatus - uses hydrogen and oxygen in closed circuit for water recovery
Inventor: SMIRA WOLFGANG
IPC: F02M25/022
Filed: 1976-02-27
Abstract: The internal combustion engine incorporates a water dissociation plant. The latter forms a fuel tank and gas generator. This system is fully enclosed and does not emit any combustion residues into atmosphere. This system can be used in motor vehicles, motor cycles and for ship and aircraft propulsion. The water dissociation apparatus uses sulphuric acid enriched water. Owing to closed cycle, the water generated is not rejected but recirculated through dissociation apparatus operating with electric current where hydrogen is separated on the cathode and oxygen on the anode.

Title: Swimming pool water sterilisation - by direct current passage through immersed copper electrodes
Inventor: SQUAZZIN ADRIANO
IPC: C02F1/46
Filed: 1976-05-04
Abstract: Plant for the sterilisation of water, specially for swimming pools, passes metal ions into the water by applying an electrical potential to electrodes immersed in the water. During the entire sterilisation period, both the minus and the plus pole of a d.c. supply are connected to copper electrodes. The gases developed are at once mixed with the water and dissolved. This prevents the side effects caused by the addition of chlorine to water. No silver ions which may be a health hazard are produced; the operating costs are much less than the ultraviolet radiation system.

Title: Electrolytic capacitor monitoring appts. - uses AC test circuit with differentiator to detect rise in voltage due to capacitance change
Inventor: GRIEGER GERHARD ING GRAD
IPC: H01G9/00
Filed: 1976-06-22
Abstract: The test circuit, for continuously monitoring an electrolytic capacitor's capacitance, has a dc voltage source (1, 2) maintaining the capacitor (4) charged to a given level.

Title: Electromagnetic operating mechanism for HV circuit breaker - has flange on operating rod moving axially between close and trip coils
Inventor: BITSCH RAINER DR ING
IPC: H01H33/28
Filed: 1976-09-30
Abstract: The HV circuit breakers has improved operating times esp. reduced opening time.

Title: Electrical controller of vehicle speed - maintains control accuracy by using selected signal modulation of higher frequency than variation of actual speed signal
Inventor: COLLONIA HARALD
IPC: F02D31/00
Filed: 1976-10-23
Abstract: An electrical controller, in partic. for controlling the speed of a vehicle, compares the actual speed with the desired speed and produces a control signal dependent on the difference between them. The actual and/or desired signals are modulated by a periodic signal of constant or almost constant frequency. The controller is developed to ensure that variation of the frequency of the periodic signal does not affect the control accuracy. This is achieved by selecting the lowest frequency of the periodic signal as an order higher than the mean frequency of variation of the actual speed signal.

Title: Secondary ion mass spectroscopy for metal determination - using various formulae to evaluate measurement of sec. ion values
Inventor: PLOG CARSTEN DIPL PHYS DR
IPC: G01N23/225
Filed: 1977-03-18
Abstract: The concn. of metals in mixts. is determined by the SIMS (secondary ion mass spectroxopy) technique. This measures the value of secondary ions of the type MeOn+. Two values J1 and J2 of two such ions for each metal are made and substd. in formula G+= gamma2m(J1/J2)/(K1-K2) + 0.5(K1+K2 where gamma = 0.98% of the width of the Gaussian distribution and K1/2 are complex values defines as K = q + 2n where q = charge sign of the sec. ion n = 0 value in the ion. From this, value G+ is evaluated. Further formulae are used to relate these factors together with others such as A (burning intensity of the ionic beam) Jp (primary current surface density) f (transmission) So (2.4.10-2 a universal constant). Also a mass dependent sensitivity is defined as M(m) - (m/235)-2.4 Used to measure metal concns. The sensitivity of SIMS is greater than other spectrographic techniques and the system described extends its use into the quantitative field.

Title: Contraction of faulty welding on tube - prevents tube breakage in die plate due to draw tension
Inventor: OPPERMANN WILLI
IPC: B21C37/08
Filed: 1977-06-23
Abstract: The draw bench for welding tubing (1) includes a die (9) and a carriage (5) that can be moved at the speed of the tube (1). A cylinder (3) operates the carriage and returns it to its starting position. The carriage has a mounting ring through which the tube (1) moves and on it are four radial punches (6). When an optical sensor (2) detects a defective welding seam on the tube (1), a control signal is produced so that the tube is radially compressed at the faulty welding by the radial punches. The required draw tension is thus reduced when the contracted tube section reaches the die plate (9), and a break of the tube due to the defective welding is prevented.
