Title: Conveyor for moving workpieces - has support arms underneath workpiece supports and fitted with friction plate
Inventor: RUPRECHT CHRISTOPH
IPC: B65G19/02
Filed: 1989-08-12
Abstract: The underside of the workpiece supports (20) is provided with support arms (23) which can swivel along the conveyor belt (17).  At the end of the support arms is fixed a friction plate (24) so that as the support arms (23) swivel so the friction surface of the friction plate (24) rises or sinks parallel to the entrainment face of the conveyor belt (10). The inclined attachment of the support arm (23) is such that the entrainment of the friction plate (24) in the conveyor direction causes the support arms to swivel in the sense of an additional lowering. The friction plate can be held at its longitudinal side by a front and rear pair of support arms. USE/ADVANTAGE - The workpiece supports can be driven and stored up and guided over points and cross-overs without wear.

Title: Waste gas cleaning - using in situ electrochemically produced peroxide(s) and hydrogen for removing oxide(s), of sulphur and nitrogen
Inventor: KUERZINGER KARL DR ING
IPC: B01D53/86
Filed: 1989-12-28
Abstract: In the cleaning of waste gases including SOx and NOx in which, after initial removal of other impurities such as fly ash, HCl and HF, the gases are desulphurised by oxidative wet scrubbing with in situ electrochemically produced peroxides to convert SOx to sulphuric acid, the novelty is that NOx removal is effected by catalytic redn. with in situ electrochemically produced hydrogen. ADVANTAGE - Safety problems are avoided by using, in the NOx removal operation, hydrogen generated during electrochemical prodn. of peroxides in the desulphurisation operation. Any excess peroxides or H2 carried over into the cleaned gas is innocuous. The process produces only re-usable by-prods., e.g. conc. sulphuric acid and opt. peroxides and H2, requires no further auxiliary chemicals and produces no waste water.

Title: Appts. for wet treatment of textile web - includes drum or endless band adjustably immersed in bath to control removal speed of web
IPC: D06B3/20
Filed: 1990-04-12
Abstract: Wet processing plant suitable for textiles in the roll is described. Rollers are employed to direct the material through the process. Squeeze rollers may be used to draw the material out of a bath. The speed of the rollers depends on the wetting period. Appts. to control the roller speed depends on the amt. of immersion the material makes in the vat. More specifically the textile material is drawn into a vat by the assistance of a directed spray. A roller system extracts the material from the liq., and the speed of the rollers is determined by the amount of immersion of the material.  The time in the fluid is a direct result of the material being held down by a floating cylinder, which is perforated sufficiently to allow fluid to penetrate the textile material, and to enter the cylinder. The difference of the level and the depth to which the cylinder and fabric sinks into the fluid represents the amount of fluid taken up by the material at any moment. If the fluid penetrates rapidly, the rollers are increased in speed, and vice-versa.

Filed: 1990-07-03
Abstract: A circuit arrangement for approximating a non-linear transfer function, particularly a logarithmic or antilogarithmic transfer function, is improved in such a manner that it obtains a much better temperature stability of its transfer characteristic. At the same time, analog/digital conversion or digital/analog conversion becomes possible. In this arrangement, the said converters are supplied with an analog reference quantity (Vref) and an analog (Vin) or digital/binary input signal (Win). The converters (20, 30) output a digital or analog output signal (Wout, Vout) on the basis of an essentially linear converter characteristic and a non-constant reference quantity (Vref) depending on the analog input or output signal (Vin, Vout) is input to the respective linear converter (20, 30). Furthermore, a method is shown, particularly for operating the aforementioned circuit arrangement and a lighting system using the aforementioned circuit arrangement. In the lighting system, the brightness of one or more light generators is changed to suit the eye. <IMAGE>

Title: Improving mechanical sepn. of solids in communal waste water treatment - by treating water with flocculating agent in an agitated pressure vessel and conveying by pressurised gas supply to filter press separator
Inventor: MUELLER LOTHAR DIPL ING
IPC: C02F11/122
Filed: 1990-08-14
Abstract: Liq. is treated with a flocculating agent before being mechanically sepd.. The treatment process is carried out shortly before the sepn. stage and takes place in one or more pressure vessels from which the liq. is conveyed by a compressed gas supply to the sepn. equipment. A finely-divided air supply is applied to the pressure vessels during the addn. of the flocculating material. The gas pressure is increased during sepn. equipment, and the remaining pressure in each vessel which has been emptied is used to start the proces in the following vessel. A pump may be used to fill and to build up the initial pressure in the pressure vessel and the filter press before the compressed gas supply is applied to raise the pressure to its required final value. USE/ADVANTAGE - This invention is used for optimal sepn. of solid particles from liqs. such as is required in the chemical industries for the recovery of prod. particles, or in the purifcn. of waste waters. The mechanical sepn. of finely divided, colloidal and widely dispersed solids by means of filter presses, centrifuges, rotary drum filters, or vacuum drum filters, after treatment with a flocculating agent, is improved by increasing the percentage of the solid particles which is retained in the filter cake.
