Title: Driving device for wipers of vehicles, in particular motor vehicles
Inventor: EPPLE ANTON
IPC: B60S1/18
Filed: 1989-01-04
Abstract: In the case of a known driving device having a connecting rod which is arranged on a crank, the crank radius may be increased in size by means of a driveable pivoting device and this leads to the wiper being transferred into an out-of-use position lying outside the wiped area. In the case of the novel driving device, a catch (7a), which secures the lever (5) in the operational position of the wiper, is provided on the crank (2). As a result, the crank radius (15) can be kept constant in normal wiping mode even with stresses occurring alternately on the wiper and on the connecting rod (13). Driving device for wipers of motor vehicles. <IMAGE>

Title: Continuous sulphur dyestuff mfr. - by baking process in double-screw reactor, followed by two=stage digestion
Inventor: LANGE ECKEHARD DIPL CHEM
IPC: B01J19/20
Filed: 1990-03-12
Abstract: Sulphur dystuffs are produced by reacting aromatic diamino or nitroamino cpds. with sulphur in a double-screw reactor at 100-300 deg.C., followed by digestion of the baked product with aq. sodium hydroxide and/or sodium sulphide solns. at 90-120 deg.C. to obtain dyestuff solns. from which commercial dyestuffs are extracted after filtration. The novelty comprises (a) adding 0.1-5 wt.% ammonium (bi)-carbonate and/or ammonium carbamate to the reactant before reaction; (b) feeding the reactant mixt. into the reactor inlet region having parallel, closely meshing, feed screws which rotate in the same direction at 3-20 rpm. and which have a length of 20-35D (D = screw diameter); (c) preheating the mixt. to 90-100 deg.C. in a compression zone of 2-4D length immediately following the inlet region; (d) converting the mixt. to the baked product by heating at 220-280 deg.C. in a subsequent 12-27D long reaction zone; (e) discharging the product under non-pressurised conditions by reaction gas expansion and quenching the product; and (f) pretreating the baking product with a 20-40% NaOH soln., for one-third to one-thirtieth of the time required for complete digestion when NaOH and Na2S are added simultaneously, and then completing digestion by adding 0.03-0.2 wt. parts Na2S per wt. part baked product. ADVANTAGE - The process allows continuous prodn. of the baked product with a high self-purifcn. effect, avoids local overheating during reaction, reduces requisite time for digesting the baked product and produces sulphur dyestuffs with improved quality and space-time yield.
Patent DE-4008502-A1 (DE)
Inventor: BUCK WALTER DR
IPC: H04B7/08
Filed: 1990-03-16
Abstract: The process described for the mobile diversity reception of digital signals by means of several individual antennas calls for the noise pulse which occurs on switching between the individual antenna signals to be orthogonal to the data signal being received. Orthogonality can be ensured by the choice of switchover time, phase and/or amplitude-curve shape. In addition, the time at which the noise pulse occurs can be chosen so that it is in a less important part of the data signal or outside time window containing decision times.

Title: Device for cleaning contaminated water - where water is treated with flocculating agent before being filtered in bag filter, to avoid clogging of filter pores
Inventor: SOHM HANSJOERG
IPC: B01D29/27
Filed: 1990-05-01
Abstract: The system consists of a mixt. and treatment process which takes place in one lower nad two upper chambers in a vertical cylindrical tube. The lower chamber communicates with the first of the two upper chambers, each of which is fitted with an agitator, via a central duct.  This first upper chamber is provided with an inlet for the raw water and receives a sepg. agent from the lower chamber. It further communicates with the second upper chamber via an opening near its base, and this third chamber has an upper outlet through which the treated water passes to a bag filter. Below the bag filter is a funnel which receives the filtered water and passes it to a drainage channel. A number of filter bags may be used and the inlets leading to them may be controlled by valves. Level probes may be used  to stop the device when the filter bag needs changing. USE/ADVANTAGE - Used for cleaning chemically or  physically contaminated water before it is disposed of into a drainage channel. It has the advantages that the water is treated so that it does not readily clog the pores of the filter bags, and that the bags can easily be exchanged for cleaning. The bags are also covered, which prevents the escape of undesirable smells.

Title: Adjustment of printing energy in typewriter - has noise generated measured to provide signal to monitor energy input
Inventor: EBERT HERMANN
IPC: B41J9/48
Filed: 1990-08-10
Abstract: The impact printer has a drum (1) around which the paper (2) is fed and a daisy wheel character (3) is forced into contact by the hammer (6) of an electromagnet (5).
