Title: Frequency divider for centring magnetostatic loudspeakers
Inventor: KREMER HELMUT
IPC: H04R3/14
Filed: 1983-07-25
Abstract: The circuit of this frequency divider for using magnetostatic loudspeakers in multi-path systems is derived from the main application No. 2105675. Since a magnetostatic loudspeaker has no centring for the amplitude mid-point (rest position), the latter shifts to the negative side, i.e. backwards, when conventional dividers are used. The arrangement shown in the circuit diagram prevents one-sided filtering out of lower frequencies through symmetrical positioning of the capacitors. The current flows through in each direction R = resistor and C = capacitor in the same order. The filtering of the capacitors is thus always the same, and the loudspeaker vibrates symmetrically about its rest position.

Patent DE-3411017-A1 (DE)
Title: Sterilisation using microwaves II
Inventor: FRITZ KARL DR
IPC: A23L3/01
Filed: 1984-03-24
Abstract: The verification of the main application shows that the major problem after completion of the process is the cooling in order to render the costly workstation free for refilling again. However, the operating space cannot be opened again until a specific temperature is reached. According to the invention, cooling means are sprayed directly into the interior and onto the object, at the corresponding pressure, in order to cool the walls, and if necessary this process is repeated a number of times, making use of appropriate thermodynamic effects.
Patent DE-3411130-A1 (DE)
Title: Mechanism for transmitting a rotary motion with a continuously variable transmission ratio
Inventor: BECKER JOHANNES DIPL ING
IPC: F16H29/20
Filed: 1984-03-26
Abstract: The invention relates to a continuously variable mechanism in which the rotary motion of an input shaft (1) is converted by a crank mechanism (2, 3, 4), the connecting rod (4) of which is guided with its free end (7) in a cam track (6), into a translational reciprocating motion. An adjustable lateral component of this translational motion is converted back into a rotary motion in a second submechanism (11, 12, 13). By appropriate shaping of the cam track (6), it is possible to achieve a linear angular velocity over a wide range, this being output to the output shaft via engageable and disengageable clutches. <IMAGE>

Title: Switching combiner for a multi-path transmission system and possible uses
Inventor: SCHNEIDER WOLFGANG DIPL ING
IPC: H04B1/74
Filed: 1984-04-28
Abstract: In a switching combiner with characteristic impedance adaptation and correct-level adaptation in each through-connection condition for at least two radio-frequency channels, different series channel impedances (Z4...Z7) can be switched to a combiner series impedance via channel activators (S1...S4). This combiner series impedance comprises as many switch-free sub-impedances (Z8, Z9) as there are interconnectable transmission channels. The channel series impedances are selected together with the sub-impedances in such a way that a characteristic impedance adaptation is guaranteed for all operating cases at the output (A) of the switching combiner. A very high level of availability is achieved by this special switching combiner design. <IMAGE>

Title: Electrical water heater
Inventor: HOEXTERMANN RUDOLF
IPC: F24H9/20
Filed: 1984-09-04
Abstract: In the case of an electrical water heater, especially a hot-water store, heating elements 1, 2, 3 can be switched on and off in at least two heating-power stages. A temperature-regulator contact arrangement T55, T54 is connected in series with the winding S of a switching relay S, S1, S2, S3. In order by using simple switching measures to prevent the maximum heating power being switched on after a power failure, the temperature-regulator contact arrangement T55, T54 operates the switching relay S, S1, S2, S3 only in a temperature band which is less than half the difference between the minimum and maximum water temperatures and is between 20 DEG C and 70 DEG C. One contact S2 of the switching relay S, S1, S2, S3 holds said relay in the picked-up position, after the switching relay has been picked up via the temperature-regulator contact arrangement T55, T54. <IMAGE>

Title: Multi-stage HCl, SO2 and NOx scrubbing process for flue gas purification, preferably downstream of fossil-fuel power stations
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/77
Filed: 1985-04-06
Abstract: A process for scrubbing flue gases downstream of combustion boilers. It is known to scrub flue gases from boilers fired by fossil fuels simultaneously using lime and EDTA. These processes have not been able to establish themselves since the economic efficiency is characterised by too high an EDTA consumption and an unstable degree of NOx separation. To create an economic process having high separation efficiency, it is proposed according to the invention that upstream of the NOx scrubbing stage is connected an SO2 and/or SO2 and HCl preliminary scrubbing stage which, as far as is possible, scrubs out the HCl and the SO2 as desired, and the crude gas thus partially purified is transferred into a scrubber (2), where in the scrubber (1) the SO2 and HCl binding is carried out preferably using limestone or hydrated lime and to reinforce the solubility of the lime compounds used, a carboxylic acid, preferably formic acid, is added which does not preclude the oxidation of CaSO3 to CaSO4, where, contrary to this gas treatment, in the stage (2) a complex is formed from the liquid sodium hydroxide solution, EDTA and/or NTA mixed with carboxylic acid, but in this case, in contrast to the first scrubbing stage an oxidation-inhibiting carboxylic acid, for example tartaric acid, is added to prevent too early an oxidation and to amplify the iron complexation of Fe2 to Fe3 and to establish the negative redox potential sodium dithionite or ...

Title: Wind motor
Inventor: FREES HORST
IPC: F03D7/02
Filed: 1985-05-10
Abstract: The wind motor has a working head, which is to be mounted on a support, can be pivoted about the vertical axis, and is provided at least with a vane rotor, possibly with an electric generator and with a brake device, which consumes electrical energy, for braking the vane rotor. In order to render the brake device independent of the line current, it has a loading weight, which acts on its brake elements in a braking manner via a resettable lever, and a triggering device, which interacts with the lever and can be driven by a low amount of electrical energy, for releasing the movement of the lever from its predetermined initial position into its working position, which effects the braking of the vane rotor.

Title: Process for the preparation of acyloxybenzenesulphonates
Inventor: AIGNER RUDOLF
IPC: C07C309/42
Filed: 1985-08-23
Abstract: A process is described for the preparation of acyloxybenzenesulphonates which are optionally substituted on the benzene ring. Liquid acyloxybenzene which is optionally substituted on the benzene ring is brought into contact with a gas mixture containing 1 to 7% by volume of SO3 at 20 to 200 DEG C. When 1 mol of the acyloxybenzene which is optionally substituted on the benzene ring has taken up 0.9 to 1.3 mol of SO3, SO3-feeding is stopped, the liquid is held at a temperature of 20 to 70 DEG C for 5 to 180 minutes and then neutralised. In this manner, acyloxybenzenesulphonates which is optionally substituted on the benzene ring can be prepared in good quality and good yield without solvents and without it being necessary to remove troublesome reaction products.
