Patent DE-4220802-A1 (DE)
Inventor: SAILE PETER DIPL ING
IPC: B23K1/005
Filed: 1992-06-25
Abstract: The invention relates to a device for soldering components to boards under the effect of a gas, with an at least two-part casing, in which there is a seal between the casing sections. It is proposed to use a liquid as the sealing agent. By this means it is possible immediately to offset mechanical stresses produced by thermal loads, thus preventing leaks in a simple manner.
Patent DE-4221554-A1 (DE)
Inventor: SCHNEIDER JOSEF
IPC: E06B3/24
Filed: 1992-07-01
Abstract: The invention relates to a frame for windows made of plastic material, having frame profiles designed as hollow profiles. Said frame profiles are connected to one another in the corner regions in a mechanical manner or by welding. In the resulting frames there are introduced at least two glass panes which enclose an interspace with an air cushion. On each frame profile there are integrally formed inwardly and outwardly angled pane-receiving webs which, when the frame is in its interconnected state, form a peripheral, narrow bearing surface for the pane borders. The pane borders themselves are connected to said bearing surface in a manner sealed with respect to diffusion. In order to compensate pressure fluctuations occurring between the panes, pressure-compensating elements are arranged in or on the profile walls directed towards the interspace.

Title: Powder paint with low stoving temp. and short stoving time - by heating components without hardener to give viscous melt, adding liq. hardener and cooling immediately with liq. nitrogen@
IPC: B01F3/18
Filed: 1992-08-04
Abstract: Prepn. of powder paints (I) from resins, extenders, hardeners, pigments and additives comprises heating and melting the components without the hardener (II) to give a viscous melt, adding liq. (II) to a stream of this melt in a metering device and immediately cooling the mixt. obtd. by means of a cryogenic coolant (III). Also claimed is powder paint (I) produced by this process. The melting range of the resin is at the curing temp. or 5-10 deg.C below it, pref. in the range 80-100 or 50-80 deg.C. The viscous melt is fed into a turbo-mixer (5) by means of a metering pump (3a, 3b), and the liq. (II) is also fed into mixer (5) (see Fig. 1). The mixt. obtd. is cooled with liq. nitrogen. USE/ADVANTAGE - The process enables the prodn. of powder paints with curing temps. approx. in the melting range of the resin component. Resins with very low m.pt. (e.g. below 70 deg.C) or very reactive hardeners can be used if the paint is stored and transported in cooled containers. The very low stoving temp. (e.g. 80-120 deg.C) and stoving time required opens up completely new applications for (I), e.g. painting wood and plastics.

Title: Process for the depolymerisation of polycaprolactam
Inventor: MUELLER WOLFGANG DIPL CHEM
IPC: B01J27/053
Filed: 1993-04-08
Abstract: The invention relates to a process for the rapid alkaline depolymerisation of polycaprolactam at relatively low temperatures in order to recover high-quality caprolactam containing only small amounts of oxidisable constituents and volatile bases. The object of the invention is to accelerate the alkaline-catalysed depolymerisation process using an activator. The problem is achieved according to the invention by using specific cocatalysts in the form of iron(II) compounds which have an activating effect on the initial step of the depolymerisation reaction. In the presence of the cocatalyst, the yield of caprolactam is increased while the depolymerisation time is shortened. The cocatalyst is added together with the alkaline catalyst.

Title: Device for feeding additional air into the exhaust conduit of an internal combustion engine
Inventor: BURGHARDT HANS-MARTIN DIPL ING
IPC: F01N3/34
Filed: 1993-05-19
Abstract: The invention relates to a device for feeding additional air into the exhaust conduit 3 of an internal combustion engine, in which the additional air delivered by an air pump is fed through an additional-air conduit 4 provided with a non return valve 6. To damp the gas vibrations at the non return valve 6, two mutually independent exhaust manifolds 2 are connected to the additional-air conduit 4 and the non return valve 6 is arranged approximately in the middle of this connecting additional-air conduit 4, two pipes 8, 9 of Helmholtz resonators 12, 13 tuned to high speeds of the internal combustion engine entering the conduit at the outlet side of the said non return valve. The resonant frequencies of the Helmholtz resonators 12, 13 are in a ratio of five to six. By virtue of the connection of the two exhaust manifolds 2 by the additional-air conduit 4, the gas vibration at a distributor chamber 5 has a sinusoidal pressure variation which can be effectively damped by the Helmholtz resonators 12, 13. By means of these measures, the life of the non return valve 6 can be increased considerably. <IMAGE>
