Patent DE-4208355-A1 (DE)
Title: Rubbish incinerator gas treatment - uses added hydrochloric acid gas at incineration to give improved mercury extraction at the washing stage
Inventor: KUBISA RYSZARD DR
IPC: B01D53/50
Filed: 1992-03-16
Abstract: To treat the exhaust gas from an incinerator, especially a rubbish incinerator, hydrochloric acid gas is added to the incineration. The amount of added hydrochloric acid gas is controlled according to the hydrochloric acid gas content of the exhaust gas before washing, which is set so that it does not reach at least 50 mg/Nm3 before washing. An oxidn. agent is added to the washing soln. pref. hydrogen peroxide. USE/ADVANTAGE - The technique is for exhaust gases which contain sulphur dioxide, hydrochloric acid gas and mercury, esp. from rubbish incineration. The dust is extracted from the gas to be treated with an acid salt wash soln. and the mercury is pref. removed by sulphide pptn. from the washing soln. The method improves the mercury removal as it is converted into mercury chloride which can be washed out of the exhaust gas.

Title: Appts for sealing neutron flux detector lance within a reactor - at position where it extends from housing tube, thus ensuring that no radioactive deposits are collected internally
Inventor: ETZER REINHARD DIPL ING
IPC: G21C17/108
Filed: 1993-02-09
Abstract: Appts. for the sealing of a lance (2) has a housing tube (5), from whose forward end (5a) the lance (2) extends, using a collar (6). The collar (6) is welded to the lance (2) and overlaps the forward end of the housing tube (5a). Within the collar (6) is a ring (9), which is connected to the collar by a spring (10), thereby pressed down to cover the annular space (8) between the forward side (5a) of the housing tube (6) and the lance (2) and hence preventing entry of any impurities into the lance. The lance (2) comprises a number of neutron detectors and their connecting cables (12) for the accurate determination of the neutron flux within a nuclear reactor. Pref. the ring (9) is made up of two parts, the first part (9a) narrowly surrounds the lance (2), the second part (9b) a flanged shaped extension of the first part is forced down by the spring (10) to cover the space (8) between lance (2) and housing tube (5). USE/ADVANTAGE - The sealing of the top of the housing tube with the lance ensures that no radioactive deposits can collect in the lance or the housing tube. During servicing of the lance no expensive cleaning out of the radioactive deposits is required. The lances do not need to be changed so often. Excess radioactivity in the bottom region of the lances beneath the reactor pressure vessel is avoided.

Title: Stepless gear with sliding element chain
Inventor: WAGNER ALBERT
IPC: F16G5/18
Filed: 1993-03-03
Abstract: The invention relates to a stepless gear in which a fixed bevel wheel 5 and a bevel wheel 6 which can be displaced axially by in each case one compressed air cylinder 7 are arranged on each of the driveshaft 8 and output shaft 9. The axial and radial adjustment of the frictionally engaging sliding element chain arranged between the bevel wheels 5 and 6 is carried out with the control slide A without an interruption in the pulling force with a difference in pressure in the two compressed air cylinders 7. The control slide A which is connected to the compressed air accumulator B and the compressed air cylinders 7 of the shafts 8 and 9 by means of lines consists of the adjustable control slide 11 with two wide control channels and of the slide bushing 12 with four narrow control channels. In the centre position of the control slide 11 the two compressed air cylinders 7 are connected to the compressed air accumulator B. In the "+" position, the path of the air via the line 14 to the compressed air cylinder 7 of the output shaft 9 is blocked during changing up and at the same time the connection to the overpressure valve Ü is opened. During changing down, the control slide 11 blocks the path of the air via the line 13 to the compressed air cylinder 7 of the driveshaft 8 in the "-" position and opens the connection to the overpressure valve Ü so that even outflowing air carries out the adjustment when there is a pressure difference in the two compressed air cylinders 7. <IMAGE>

Title: Sailboard sail having at least one camber inducer fixed thereon as well as associated components
Inventor: SCHLITTENBAUER FRANZ
IPC: B63H9/06
Filed: 1993-08-27
Abstract: A sailboard sail (4) having at least one camber inducer (6, 26) fixed thereon and a sail batten (8) proceeding therefrom is characterised in that the camber inducer is fixed essentially in its final position and in a way which prevents it from substantially tipping about all three main axes. It is preferred for the camber inducer (6, 26) to be closed around the mast cross-section, but to be of variable length. Owing to the specified fixing of the camber inducer (6, 26) on the sail (4), there is no need for the camber inducer to be gripped and aligned when introducing the mast into the mast pocket, nor is there any need to readjust the camber inducer when changing the luff tension. <IMAGE>

Title: Device for metering liquids from a supply container
Inventor: GRAF HANS
IPC: G01F11/02
Filed: 1993-10-12
Abstract: A description is given of a device for metering liquids from a supply container, having a metering piston which, for aspirating an adjustable liquid quantity, is guided in a metering cylinder, the metering cylinder being connected to a valve block which has a valve system consisting of an inlet valve or aspirating valve and an outlet valve and being able to be fitted firmly to the supply container.
