Patent DE-4202056-A1 (DE)
Inventor: JAEGER TILO DR ING
IPC: E06B3/263
Filed: 1992-01-25
Abstract: 2.1 In the known compound profiles, the profile rails (10, 11) are interconnected by webs which pass through the insulating layer and are welded to the inner walls of the profile rails. As the profile rails and the metal webs are provided with a surface-protection coating (zinc coating), the quality of the welding is impaired. The aim of the invention is to render the welding of the metal webs to the profile rails and also the use of other fastening means superfluous. 2.2 To achieve this aim, the webs are designed in one piece with the profile rails (10, 11) or with profile rail parts which partially delimit the hollow chambers (12, 13). 2.3 The compound profile is used in the construction industry. <IMAGE>
Patent DE-4203162-A1 (DE)
IPC: B44C1/175
Filed: 1992-02-05
Abstract: The invention relates to a procedure and an apparatus for the production of transfer sheets for firing of images, characters and decors on ceramic objects to be fired, such as items of crockery, tiles or on objects which remain dimensionally stable at a high heating temperature, the transfer sheets provided with the image and/or character and/or decor being stuck to the objects on the colouring pigment side and being fired or heated together with said objects. According to the invention, provision is made for the ceramic colouring pigments to be made up in an aqueous, organic solution containing a combustion-retarding additive and to be transferred onto the transfer sheet by the gravure printing method using printing formes having a cup depth of at least 50-120  mu , the colouring pigments being maintained in a homogeneous distribution in the prepared solution prior to their transfer onto the gravure cylinder. To carry out the method, only a slight change to the intaglio printing machines is required, namely in such a way that a homogeniser (6), which maintains the homogeneous distribution of the colouring pigments in the aqueous organic solution, is arranged in the ink supply container (4). By means of the method, all the disadvantages of previous methods, namely amount of time required, lack of precision and non-standardised production, are avoided. <IMAGE>

Title: Neutralising the pH value of acid water - has control to regulate the neutralising agent feed according to comparison of nominal and actual pH values
Inventor: MOHR DIETER DIPL ING
IPC: C02F1/66
Filed: 1992-10-02
Abstract: To neutralise the pH value of acid water contg. different acid types, with different titration curves, the feed of neutralising agent in a closed control circuit is set by a setting value (y), provided by a control (18) with an integral component from the nominal (w) and actual (x) pH value. The acid components are estimated from the integral part (21) of the control (18), and are taken to give the best feed structure of the neutralising agent. Also claimed is an appts. with a control (18) to set the feed of neutralising agent with at last an integrating behaviour. A comparator (19) gives the control difference (xd) from a preset nominal value (w) and the actual (x) pH value. A system gives the content of the different acid types according to the integral section (21) of the control (18) and matching the control (18). USE/ADVANTAGE - The system is used to assess and modify waste water, esp. from chemical plants, for on-site cleaning before passing into sewage disposal system to prevent damage to bacteria cultures in the sewage tanks. The operation determines the types of acid present, for effective neutralisation, with an accurate pH setting in the water.

Title: Internal combustion engine with a plurality of cylinders
Inventor: WAAL SEN JAKOB
IPC: F02M19/06
Filed: 1993-03-11
Abstract: The internal combustion engine comprises at least one inlet valve and at least one exhaust valve for each cylinder, the valves being opened and closed by the cams of at least one camshaft, an intake pipe system for supplying the cylinders, an exhaust pipe system for removal of the exhaust gases from the cylinders and a device for feeding in fuel.

The cam passes through the limit range of this control curve when the induction stroke through an opened inlet valve of another cylinder has begun. The end of the control curve of the exhaust cam and the start of the control curve of the inlet cam of each cylinder are so synchronised with one another in their angle of rotation that the exhaust valve and the inlet valve of one and the same cylinder during a piston stroke travel of 10 mm are simultaneously closed in the area of the top piston reversal point.
