Title: Process for the chemical purification of waste water by contact filters
Inventor: PETERSON GUNNAR
IPC: B01D37/03
Filed: 1981-02-05
Abstract: Process for the chemical purification of waste water by contact filters, various precipitants and flocculants being added to the waste water by two metering units for various chemicals. The waste water containing added precipitants and flocculants is fed to the filters by one of two pump groups, of which one has a higher throughput than the other. The said one pump group is switched in if the inflow to the sewage treatment plant is below a certain given level, and the said second pump group is switched in if the inflow is above this level. The said inflow level in practical operation often has the same order of magnitude as the so-called rated inflow for the plant. The two metering units are connected to the two pump groups in such a way that a first chemical is automatically added to the waste water when the said one pump group is switched in and a second chemical is added to the waste water when the said second pump group is switched in. The said first chemical added is preferably an aluminium compound, for example aluminium sulphate, and the said second chemical added is preferably an iron salt, for example iron chloride.

Title: Circuit arrangement for an electric motor of a wiper system which is fed from a voltage source
Inventor: ANDREI-ALEXANDRU MARCEL DIPL I
IPC: B60S1/08
Filed: 1981-09-11
Abstract: The invention relates to a circuit arrangement for an electric motor of a wiper system in which the wiper is stored outside the wiped field in a so-called, lowered parked position, for which purpose the direction of rotation of the electric motor (11) is changed after the wiper system is switched off. This change in direction of rotation is controlled via a pole reversal switch (40) which is switched by a relay (41) which is excited only for the purpose of moving the wipers into the lowered parked position. The normal wiping operation is therefore also possible if the relay were to become defective. <IMAGE>

Title: Rope drum for the rope drive of a window lifter
IPC: B60J1/17
Filed: 1981-11-09
Abstract: A rope drum (40) for the rope drive of a window lifter, having a conical winding portion (54), is proposed. This ensures that, as the rope correspondingly winds round the rope drum (40), the rope pull generated by the rope drum (40) is at its greatest when the window is closed or almost closed. The frictional force between the window and gaskets, which is increased in this region, is therefore overcome without further action, even when the drive motor is of low power. <IMAGE>

Title: Internal-combustion engine with a lambda control
Inventor: EMMENTHAL KLAUS-DIETER
IPC: F02D41/14
Filed: 1982-04-17
Abstract: In an injection internal-combustion engine which is equipped with a lambda control (13) for determining the injection time of the injection nozzles (16, 17, 18, 19), the injection nozzles are triggered as a function of the speed and load of the engine according to a stored function, and only when the operating point of the engine enters a predetermined characteristic curve range (12, 12a), to which the fuel air ratio 1 is assigned, is the probe (6), which is connected to the lambda control (13) and senses the oxygen partial pressure in the exhaust system (1), exposed by means of a valve (5) to the exhaust gas flow, so that only then is it determined in a memory and comparator device (11) whether or not the stored function has to be corrected by a correction factor due to ageing phenomena in the injection system. <IMAGE>
Patent DE-3214782-A1 (DE)
Title: Burner
IPC: F23D14/48
Filed: 1982-04-21
Abstract: The invention relates to a burner for a mixture consisting of fuel and air, which is shaped into a narrow rectangular flow cross-section in a mixing chamber, so that a narrow elongate flame can be formed. Such burners cause during operation considerable noise nuisance. In order to avoid this, it is envisaged according to the invention to connect peripheral zones, following the walls of the mixing chamber formed with a rectangular cross-section, to the mutually opposite longitudinal edges, which zones open in a diverging manner in relation to one another in the direction of flow. By this measure, and by other proposed constructional embodiments, it can be brought about that the noise level is lowered by at least 10 dB.

Title: Rocker lever arrangement in an internal combustion engine
Inventor: FUHRMANN WOLFGANG DIPL ING
IPC: F01L1/18
Filed: 1982-08-11
Abstract: Starting from a rocker lever arrangement in an internal combustion engine, with at least one rocker lever pivotably mounted on the rocker shaft and with a spring for pressing the rocker lever against a support, the object to be solved is to provide a rocker lever arrangement in which wobbling movements of the rocker lever are avoided. This is achieved by the fact that, first of all, a butting element made of a relatively soft and easy to run in sliding bearing material is arranged between that end face of the rocker lever which faces the rocker shaft bearing bracket and the rocker shaft bearing bracket, that, secondly, the rocker lever end faces are given flat side faces perpendicular to the rocker shaft in the region of their support against the butting element or against the spring, and that, thirdly, the spring is a spring which exerts the same force on the rocker lever all the way round, in particular a rotationally symmetrical leaf spring.
