Apparatus for soldering components mounted at printed wiring boards

INVENTOR: FRITZ HESS INVENTION: APPARATUS FOR SOLDERING COMPONENTS MOUNTED AT PRINTED WIRING BOARDS ABSTRACT OF THE DISCLOSURE A conveyor device containing transport frames, each of which is structured for receiving a printed circuit or wiring board carrying circuit components and guided at their leading and their trailing corners by related guide tracks, leads the trans-port frames to a solder bath, where the transport device lowers the transport frames together with the printed circuit boards to-wards the solder bath and again raises the same therefrom. During the course of travel of a transport frame containing a printed cir-cuit board carrying one or more of the circuit components through the solder bath one side of the printed circuit board is immersed into the solder bath and then again lifted out of the solder bath. On the one hand, to prevent that the connection leads or wires protruding from the printed circuit board, during the immersion in-to the soldering bath, hold back air and, on the other hand, to prevent that during lift-out of the printed circuit board from the¦ solder bath solder bridges will form between the protruding leads or wires, the guide tracks, viewed in the direction of conveying, possess descending ramps whose spacing from one another is less than the length of a transport frame. Following the descending ramps are ascending ramps, whose spacing from one another approxi-mately corresponds to the length of a transport frame. The equip-ment is particularly suitable for the series or mass production sol-dering of printed circuit boards which carry similar types of circuit components.

Railway vehicle

Véhicule ferroviaire pour usage urbain comportant au moins un bogie motorisé et un bogie porteur. Ce dernier est muni de roues de moindre diamètre que celles du bogie motorisé, ce qui permet le recours à un abaissement de toute la surface de plancher du véhicule sauf à l'endroit où se trouve le bogie motorisé. Cet abaissement permet l'utilisation d'un seul marchepied pour les usagers, ce qui permet d'accélérer l'entrée et la sortie des voyageurs.

Method and equipment to solder printed-circuit assemblies

To match the soldering of an assembled printed-circuit board (13) to its assembly configuration, the circuit board (13) is brought in contact with a soldering wave (21) for a first time along a predetermined path (57, 58), and thereupon the circuit board is rotated about a vertical axis and is brought into contact, preferably with the same soldering save (21), a second time, along predetermined paths from the same direction during its motion along the paths (57, 58). The printed circuit board (13) may be rotated by an angle (α) depending on the assembly configuration relative to the direction of flow (56) of the soldering wave (21).

Running sole used by athlete - is for foot provided with support strap and has foot-shaped locating surface and underside or running surface

In the area of the locating surface (2) projections (7) are provided which stand proud of the surface. Such projections are pyramidal or conical and are arranged in a regular pattern in a limited zone in the front foot area. The projections are arranged in the edge area of at least one recess (5) and are also present on the running sole on a form part (6) embedded in the sole (1). USE/ADVANTAGE - A running sole which excludes relative movements between it and the support strap.
