IPC: B29C65/00
Filed: 1989-07-18
Abstract: A welding device for plastics, to produce weld seams on several sides of materials and of films in particular, has at least one tool with welding edges. At least one welding tool is designed to simultaneously weld two parts which are at an angle to each other. The device has a top welding tool and lower spring-loaded tool, the film packs being moved along between them. The device has a transverse welding tool part (5) for each tool and also two lengthwise welding parts (6). The transverse part (5) has three continuous edge sections (7, 8) on the side towards the lower welding tool, the centre section (7) joining the ends of the longitudinal egde sections (9). Two films (12, 13) of equal width are fed in (10) and e.g. a stack of paper bags (16) is moved into position between them. The films (12, 13) are welded together to form a package (37) which has four weld seams, namely two produced in turn by the same transverse tool (17, 18) and two longitudinal seams (19) produced simultaneously with the one transverse seam (17); each of the longitudinal seams extends to the relevant longitudinal edge (14) of the films (12, 13). The shorter transverse seam (17) is made by the welding edge (7) and it joins the longitudinal seams (19).  The longer seam (18) is made by the welding edges (7) and (8) and it extends to the longitudinal edges (14) of the films (12, 13). ADVANTAGE - Instead of making successive welds in one direction after another (e.g. using films for packaging purposes) the device makes two welds at the same time and thus saves time and costs. The equipment has a simple set-up.

Patent DE-4006387-A1 (DE)
Inventor: CONZELMANN GERHARD DIPL PHYS
IPC: H02J7/24
Filed: 1990-03-01
Abstract: Proposed is a voltage controller (4) for a generator (1), in particular for use in motor vehicles, which, by switching the field current on and off by means of a controlled semiconductor, and acting together with a freewheel loop, generates a medium field current in the field coil (2) of the generator (1) so that the generator voltage remains approximately constant, independent of the load and the rotational speed. The voltage controller (4) includes an integrally acting component to compensate for load-dependent and speed-dependent errors, which is generated by means of a non-linear integrator from the relative time-to-make of the current flowing in the field coil (2) and is fed back to the voltage-controller control loop. Non-linearity of the integrator output is ensured by virtue of the fact that, to form the correction function, the part of the cycle while the current is flowing through the generator field coil (2) and through the controlled semiconductor is processed differently from the part of the cycle while current is flowing through the field coil (2) and through the freewheel diode.

The feature is that the separator (10) has pores with a dia of 10-50 micron, pref 10-30 micron, and that the acid content is such that all pores are filled with acid. The cells also contain porous membranes, with a pore size of 2-10 micron, between the ends of the separators and the walls of the battery. The separators are pref made of a felt consisting of plastic fibres of the type : polyethylene, polyester, polyterephthalate and polyvinyl-resin.  The metal electrodes used are an Sb-free alloy of Pb, featuring a Ag-content of 0.005-0.02 wt% or Co with a content of 0.005-0.03 wt%. The electrolyte pref contains dissolved metal salts or a mixt from the gp : Ag, Co, Sb, Ni in a concn of 0.055-0.03 wt%. USE/ADVANTAGE - The battery can function with a lower gas recombinationm efficiency because it spends a small part of its oeprational life, from 2-3% to 20-40%, being  charged up. For the rest of the time the battery generates only small amts of gas. The batteries can be made with simpler lid construction without requiring a liquid trap and thinner walls, because the gas-pressure is lower. The replacement of glass-fibres by plastic fibres also reduces cost.
