Title: Device for two-sided coating of material webs, in particular of paper webs
Inventor: BLOSER EKKEHARD
IPC: B05C9/04
Filed: 1988-12-02
Abstract: The known devices for two-sided coating of material webs, in particular paper webs, for alternative operation as a gluing press or as a spreading device have two adjacently arranged pressing rollers, one of which can be pivoted against the other, guide rollers which guide the material web in gluing press operation through the pressing nip between the two pressing rollers, an application and metering system which can be pivoted against a pressing roller outside the pressing nip, and guide rollers which guide the web into the region between said pressing roller and the application and metering system, the web being deflected by the pressing roller. According to the invention, one pressing roller (3) has a very hard surface and the other pressing roller (2) has a soft surface, and an application and metering system (12) is assigned only to the pressing roller (2) with the soft surface. A second spreading device with a counter roller (13) and an application and metering system (14) follows the pressing rollers (2, 3) on the web outlet side. <IMAGE>

Title: Bus, in particular coach
Inventor: STURM CHRISTIAN DIPL ING
IPC: B60S1/50
Filed: 1988-11-23
Abstract: In the case of known buses only the rear glass work and not, however the side glass work, is assigned a window-cleaning system. In unfavourable weather and road conditions the side windows become dirty and this greatly impairs the visibility for the passengers on board. This is of disadvantage in particular in coaches. The novel bus (1) has a window-cleaning system (6) revolving in the region of the rear and side glass work (3, 2). With this cleaning system (6), which is common to all of the window surfaces, effective cleaning of those window surfaces which the passengers look out of is possible in an efficient and low-wear manner. Coaches. <IMAGE>

Title: IC engine exhaust system - incorporates Helmholtz resonator to generate pressure wave to increase power
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N1/02
Filed: 1989-05-20
Abstract: The pressure wave system is for a naturally aspirated multi-cylinder piston engine. It uses a collector tube in thrust nozzle form.

Title: Knitter selection - uses at least two successive selection pulses for each component move to restrict movement speed
Inventor: KASE OLDRICH DIPL ING
IPC: D04B15/78
Filed: 1989-08-29
Abstract: In the electro-magnetic change system, to select operating components of a knitting machine, at least two successive selection pulses act on each unit, synchronised with the movement of the component in terms of time and space.

Inventor: GUETLICH KARL-FRIEDRICH DIPL P
IPC: H01M10/52
Filed: 1990-05-12
Abstract: In a lead accumulator, the recombination device normally mounted in an exposed position, for example on the lid or in the closure stopper, has been moved into the interior of the housing above the set of plates. It comprises a sequence of layers of hydrophobised mineral-fibre or active-carbon mats (2, 3) which are embedded in a metal sleeve (1) which is open at both sides and is preferably composed of lead, a central layer (2) being impregnated with catalyst material. The solid mechanical connection of the metal sleeve to a terminal bridge 5 effectively removes the heat of recombination from the catalyst layer and, in addition, prevents an electrostatic discharge which could result in an ignition of the gases formed by electrolysis. <IMAGE>

Patent DE-4019591-A1 (DE)
Title: Saddle coupling - simplifies clutch plate assembly and improves abrasion resistance
IPC: B62D53/08
Filed: 1990-06-20
Abstract: A saddle coupling with a clutch plate is claimed for connecting a support with a traction engine. This consists of a ductile cast foundation material contg. spherical graphite. This material is heat treated to give it a thin, hard structured, abrasion resistant layer. The foundation material is suitably ferrite contg. up to 70% perlite which when heat treated gives a hardened outer layer (0.1-3 mm thick) which can consist of perlite, sorbite, troosite, bainite, or martensite or a combination of these. The hardened outer layer of the finished coupling comprises at least 20% of the surface but 100% of the rim area. USE/ADVANTAGE - Simplifies the clutch plate assembly, improves friction resistance, lubrication is unnecessary. In an example: a clutch plate was made from an alloy of the following compsn. (wt.%); C 3.2-3.9; Si 1.8-3.0; Mn 0.05-0.8; P 0.02-0.1, S 0.002-0.015; Cu 0.02-1.1; Mg 0.02-0.08, and the remainder Fe. This was heated with a flame on the surface to above the ferrite-austenite temp. in the Fe matrix (700-900 deg.C). Under these conditions some of the graphite went into soln. The heating source was removed and cooling quickly applied to the back of the plate in order to restrict the hardening to just a thin outer layer.
