Title: Flame-inhibiting and formaldehyde elimination-reducing material which can be added to chipboard
Inventor: HERR ALFONS K
IPC: B27N9/00
Filed: 1985-10-19
Abstract: The value of chipboard is reduced to an extraordinary extent and its use significantly restricted if it eliminates formaldehyde gas after gluing with urea-formaldehyde resins. Processes which have been disclosed for reducing this elimination generally reduce the strength of the chipboard produced thereby or cannot be employed economically. The value of the chipboard can be increased by flameproofing it. Both a reduction in the release of formaldehyde and a significant reduction in the combustibility or even incombustibility is achieved in accordance with the invention by adding a material comprising organic fibres with adducted ammonium phosphate and urea and included boric acid particles to the starting raw materials for chipboard.

Patent DE-3606884-A1 (DE)
Title: Tetrad adder in 5311 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1986-03-03
Abstract: The tetrad adder according to the subject of the invention has a dual full adder only to process the value 5, since the main circuit processes the value 1. As soon as the sum or partial sum 5 is reached in the main circuit (1), this sum or partial sum is branched off as an inner carry with the value 5, and processed in the dual full adder (3). Thus, a possible partial summand with the value 5, or two possible partial summands with the value 5, and a possibly occurring inner carry with the value 5, are processed in the dual full adder (3). <IMAGE>

Title: Process and alloy for hot-galvanising
Inventor: HAENSEL GUENTHER DIPL ING
IPC: C23C2/10
Filed: 1987-04-30
Abstract: A hot-galvanising process is described, in particular for producing zinc layer thicknesses of between 10 and 40  mu m by means of hot galvanising on individual steel components, a lead bath being used which is saturated with zinc at the galvanising temperature, and an only very thin zinc layer being maintained on the surface of the lead baths depending on the desired layer thickness on the steel, or the molten lead being completely free of molten zinc at the point where the piece to be galvanised is immersed. In this case, an addition of tin in various quantities to the molten lead-zinc is particularly advantageous, as a result of which the zinc solubility and wettability are considerably improved, so that not even a flux cover is required during the galvanisation. <IMAGE>
