Title: Electrophoresis unit control circuit - provides graphical representation for any separation lengths and transmission characteristics using scanning head and comparator
Inventor: HIRSCHMANN JOSEF
IPC: G01N27/447
Filed: 1978-04-18
Abstract: A control circuit is for an electrophoresis unit having a photoelectric scanning head producing signals when moved w.r.t. a specimen to determine its light transmission coefficient along a given path. The control circuit minimises errors caused by misalignment of the specimen w.r.t. the head. It gives a graphical output independent of the characteristics or length of the electrophoretic separation region. The output signal from the head is fed to a memory (5) whose output signal is held constant as the relative movement between the head and specimen begins. The head's output signal is also fed to a comparator (6). A warning signal is released if the output signal of the latter changes in a prescribed direction.

Patent DE-2921827-A1 (DE)
Inventor: KERNER RUDOLF ING GRAD
IPC: B23K35/36
Filed: 1979-05-29
Abstract: The halogen free flux is appropriate for the brazing based on rosin, particularly for the production of electronic elements. The flux has two basic versions. The version (1) is a liquid rosin flux wherein it is used as a solvent water and alkanols miscible with water and as an activator the diethanolamine and the dicarboxylic acids saturated and unsaturated. The flux is appropriate for application by foaming, wetting or spraying for brazing, quenching or welding by vibrations. The version (2) is a solid rosin flux, wherein saturated aliphatic monocarboxylic acids are used as softeners, and diethanolamine and dicarbocylic saturated and unsaturated acids are used as activator. The version (2) is appropriate for filling or coating brazing moulded parts, brazing pastes, etc.... The advantages of such halogen free flux are an important reduction of the brazing surface tension, a decrease of the brazing bridges. The halogen free fluxes allow the braising of brass, steel and nickel, reach during manual brazing a flow speed similar to that obtained with most halogen flux and allow a significant increase of the surface resistance with an easy and simple separation and removal of waste.
