Title: Treating cyanide-contg. effluent, e.g. from electroplating industry - by preheating effluent and then mixing with hydrogen peroxide.
Inventor: GUTEKUNST GERHARD DR
IPC: C02F9/00
Filed: 1992-08-27
Abstract: Treating cyanide-contg. effluent by oxidising the cyanide cpds. with hydrogen peroxide, comprises preheating the undiluted effluent to 35-50 (40) deg.C and then introducing the preheated effluent into a pipe reactor, and then mixing with hydrogen peroxide at the reactor entrance and then directing the mixt. through the reactor. The untreated effluent is pref. introduced into the reactor in a flow cycle opposing that of the treated effluent. The untreated effluent is pref. preheated in a heater, pref. a through-flow heater. Pref. the cyanide content of the effluent is determined and a slight stoichiometric excess of hydrogen peroxide is added. The pipe reactor pref. has a throttle valve on the inlet side to control the flow through the reactor. USE/ADVANTAGE - Useful for treating effluent from the electroplating industry. Process is economic and safe to the environment.

Title: Vehicle windscreen wipers drive motor - has first contact arm cooperating with rib on disc to maintain sufficient distance between contact and disc in parked position
Inventor: ANDREI-ALEXANDRU MARCEL
IPC: B60S1/08
Filed: 1992-08-27
Abstract: The windscreen wipers parked position switch has a switch disc (1) on a drive part of the motor and friction contact springs (9,10,11) on the disc. A first contact (9) cooperates with a rib (7) on the disc (1). In the parked position, the first contact (9) lies in a gap in the disc (1). A second contact (10) constantly cooperates with the disc (1) and the third occasionally cooperates with it. One edge (6) of the disc gap (2) is formed as a rib (7) extending in the circumferential direction of the disc (1) and projecting from the plane of the disc perpendicular to the direction of the first contact arm (9). The latter lies along the edge (8,8') of the rib (7). After leaving the rib (7) and reaching the edge (6) of the gap (2) the contact arm (9) drops into the gap (2). To reduce lack of precision due to wear of the contacts (13) and the disc (1), the contacts (13) are made of harder material than the disc (1). ADVANTAGE - Reduces danger of contacts fusing into plastic of drive wheel. A simple and efficient device with increased functional capabilities.

Title: Wool decatising process - utilises specific dampness and temp. to glaze the cloth.
Inventor: RIEDEL DIETER DIPL ING
IPC: D06C7/00
Filed: 1992-10-09
Abstract: A process to continuously decatise textile material in roll form, with a wet process of cleaning, and pressing damp material to set the woven, knitted or similar cloth. Before setting, the remaining dampness in the cloth is reduced to between 20 and 40%. The cloth of woolen or woolen mixt. (1) is washed and drained at stage (2). This is followed by reduction of the residual dampness (3). It is brought down to a residual dampness of 20 to 40%. It is proposed that this should be achieved by a vacuum extraction technique in preference to hydro-extraction, which would interupt the continuity. ADVANTAGE - The process enables the woolen or woolen mixt. cloth to be glazed, keeping the shape and handle desired, with a reduction of outlay on chemical additives.

Title: Gap sealing system with automatic regulation
Inventor: BIRKHOFER KARL HEINZ
IPC: F16J15/34
Filed: 1992-12-30
Abstract: The conical outer diameter (41) of the rotor (2) and the conical inner bore (40) of the axially displaceable bush (8) are smooth in the area of the laminar sealing face (D).

Title: Feeding means for a beam
Inventor: SCHMIDLER RICHARD
IPC: B27M1/08
Filed: 1993-05-28
Abstract: A feeding means for a beam which is to be moved in a defined manner in working stations has a driver in the form of the cylindrical drill, which is moved by the dragging member and by means of which a driving hole has previously been made in the beam region which is at the front in the moving direction.

Title: Locking device
Inventor: NEUDECKER ANDREAS
IPC: G05G5/06
Filed: 1993-09-09
Abstract: The invention relates to a locking device for securing adjusting positions of an actuating element. It is known to press or to screw a locking device into a bore of a housing. These solutions concurrently require a relatively thick-walled housing, in order that sufficient fastening is ensured and tilting is excluded. It is the object of the invention to propose a fastening for a locking element with which the latter is effectively held, even in thin-walled housings. According to the invention, an outer housing (2) of the locking device (1) has a securing sleeve (11) assigned to it, which is supported on a housing wall (8) and which is connected to the outer housing (2) in a positive or non-positive manner. <IMAGE>

Title: Recovery of mercury@ from combustion flue gases
Inventor: MEININGER SIEGFRIED DIPL ING
IPC: C02F1/42
Filed: 1993-10-04
Abstract: In a new procedure for cleaning combustion exhaust gas which contains mercury using an acidic scrubbing liquid, the concentration of hydrochloric acid in the scrubbing liquid is maintained at between 5 and 30 wt.%, and the mercury is removed from this liquid by an ion-exchange resin. This resin is later regenerated and the mercury is recovered from the regeneration liquid by electrolysis.Also claimed is an appts. for carrying out this procedure, which is applied to a flue gas scrubbing system (1) consisting of quencher (2) and a main scrubber unit (15). Cleaning systems (7,20) consisting of a mechanical filter (8), an ion-exchange system (9) and an A-K filter (10) are located in sections (11,18) of the quencher spray circuit (5) and the sludge outlet (17) of the main scrubbing unit.A weak alkaline resin is used and is regenerated with sodium sulphate. Calcium hydroxide is added to assist the electrolysis. The regeneration liquids from both the ion-exchange units undergo the same electrolysis process. Further electrolysis cells are provided for separating heavy metals from the sludge collected in the sumps (16,17) of the quencher and the main scrubbing unit. The circuit of the first stage (16) of the main scrubber also undergoes a mercury removal process (103,104). The quencher circulating and sludge liquids are passed through the cleaning units at below 5 bar, and the circulating liquid is sprayed into the quencher at high pressure. In addition to being cooled to saturation by the evaporation of water, the flue gas is also humidified with sump liquid.The mechanical filters (8) are in the form of folded candle filters. The ion-exchange systems (9) contain four cartridges which are piped together and are regenerated one at a time. The electrolysis cells have overflows connected to the regeneration medium vessels and their volumes are about 0.5 cubic metre. The cells and/or their delivery pipes are insulated and preferably cooled, and are located in ventilated housings. A system for mixing calcium hydroxide and spraying it into the high-temp. part of the furnace is associated with the resin regeneration system. Electrolysis separators (101,102,104) for mercury and other heavy metals are provided downstream of the ion-exchange systems in the quencher spray circuit (5) and the liquid circuit of the main scrubber unit.

Title: Connection device for multipart luminaires, in particular luminaires having at least one fluorescent lamp
Inventor: BAETZ RUDI
IPC: F21V23/00
Filed: 1993-10-08
Abstract: Multipart luminaires (10), in particular with a fluorescent lamp (11), have a rail (12) which can be fastened, for example, to a room ceiling and an implement carrier (tool carrier, accessory rack) (13) which can be fixed to the rail (12). The connection of these two parts, which consist of sheet steel, is carried out by rotating brackets (14) which in turn are arranged such that they can be rotated on the implement carrier (13) by means of plastic parts, to be specific a handle piece (20) and a fastening part (26). These plastic parts are subject to aging, with the result that there is the risk of a fracture (breakage) after a certain time and the connection between the plastic parts is released, so that the implement carrier (13) of the luminaire (10) may fall down. A crash protection is provided in order to avoid this. This crash protection has securing tongues (17) on the rotating brackets (14). The implement carrier (13) is provided with longitudinal edges (29) which are angled off towards the outside and which engage over the securing tongues (17) when the rotating brackets (14) are in their active position in which they connect the implement carrier (13) to the rail (12). When the connection between the plastic parts is released, the implement carrier (13) gets stuck on the securing tongues (17) of the rotating brackets (14) which in turn are in engagement with the rail (12). <IMAGE>
