Patent DE-4034275-A1 (DE)
Title: Appts. for forming gaps for slide fastener
IPC: A44B19/58
Filed: 1990-10-27
Abstract: A gapping machine for slide or zip fasteners has a controlled buffer loop system to even out the fabric tension, and gapping means to clamp and hold the fabric while the coupling elements are cut to form a gap. Sensor means control the fabric drive rollers to ensure that the gaps are in exactly the required places.     A movable rotatable buffer roller (8) controls tension in the slide fastener stringer fabric (2). A sensor roller (10) detects actual movement of the stringer which is compared with the required movement by a controller (11) working the drive rollers (12) through a stepper motor (13). At the required length, the drive rolls stop and actuators (21, 22) clamp and hold the stringer fabric while the fastener connectors are cut forming a gap in the stringer.

Title: Welding area marker - is a reflecting or fluorescent medium to give welder a better view of the workpiece through the tinted goggles or face mask
Inventor: SCHLOEGEL ANTON
IPC: B23K35/00
Filed: 1990-11-06
Abstract: To give a welder a better view of the work at a workpiece, esp. on protective gas or shielded arc welding and electro welding, a medium is applied over the working area which is reflective or luminescent or mirrors through the effects of welding rays, esp. ultra-violet and infra-red rays. The medium is in the form of a crayon, or a pen and partic. a felt tipped pen, a paste or a grease. The carrier for the reflecting or luminescent medium takes up slag developed during welding and on heating, burns away without residue. The luminescent medium contains nightlight pigments or it is a phosphoresence material with a crystal structure which is damaged by a small amt. of foreign matter. The fluorescent material glows when under ultra-violet light. ADVANTAGE - The medium reacts on welding so that partic. at the start, the welder can see the workpiece and working area through the tinted goggles or face mask without having to 'work blind' at the outset.

Patent DE-4140373-A1 (DE)
IPC: C07C67/62
Filed: 1991-12-07
Abstract: Described is a method of recovering, in a pure, substantially neutral state, non-volatile organic compounds containing reactive olefinic double bonds from a starting liquid mixture containing such compounds, together with lesser amounts of acid reaction constituents and/or appropriate auxiliaries. The method calls for the mixture to be neutralized, the salts thus formed to be separated off and pure products to be recovered which, even without distilling them, have both low residual acid numbers and low colour levels, using finely powdered solid oxides, carbonates and/or hydroxides of alkali metals and/or alkaline-earth metals as neutralizing agents and subsequently separating off the liquid organic phase from the solid phase formed. The method proposed is characterized in that the neutralization is carried out as follows: the solid neutralizing agent is added to the hot starting mixture in an amount which is at least approximately stoichiometric with respect to the acid number of the starting mixture; simultaneously or subsequently, a limited amount of water is added; the mixture is neutralized by mixing at least for a period of several minutes; the water is distilled off from the hot reaction mixture at reduced pressure; and the solids now present are separated from the liquid phase. A special embodiment of the invention concerns the use of this method for inhibitor exchange in mixtures of substances with reactive radical groups. In this embodiment, an inhibitor intended to act during the manufacturing process and capable of reacting with bases to form salts is exchanged for inhibitors intended to act in the particular application of the product manufactured and which may be of any kind and present in any amount.
