Patent DE-3307448-A1 (DE)
Title: Writing instrument for ink or Indian ink
Inventor: WESTPHAL WERNER
IPC: B43K5/08
Filed: 1983-03-03
Abstract: The writing instrument is provided with two chambers, with a relatively large storage chamber 2 and a smaller dispensing chamber 9. The connecting bore between these two chambers is closed by a valve 6, 7 which has a lift and displacement body 8 which floats in the Indian ink or ink in the dispensing chamber 9. When the dispensing chamber 9 is correspondingly filled, this lift and displacement body 8 ensures that the valve is closed. If the level drops, there is consequently an automatic opening and thus a continuing resupply of Indian ink or ink from the storage chamber. In the dispensing chamber, there is essentially the same amount of liquid, so that correspondingly uniform writing behaviour is ensured. The valve 6, 7 can additionally be pretensioned by the lift force, as well as by a spring force in the closing direction, in order to ensure reliable closing even in the case of essentially horizontal writing (Fig. 1). <IMAGE>

Title: Combined non-return valve and preliminary shut-off valve
Inventor: SCHMIDT HEINZ
IPC: F16K15/18
Filed: 1983-04-23
Abstract: A combined non-return valve and preliminary shut-off valve for installation in a housing hole in a sanitary fitting is described, in which the annular closure element of the non-return valve coaxially surrounds the valve spindle belonging to the preliminary shut-off valve. The closure element comprises an axially displaceable annular plate, on whose external circumference a soft lip seal is mounted. In the closed position of the non-return valve, the latter interacts with a seating surface on an external bush. Constructed on an outwardly projecting collar of an inner bush which surrounds the valve spindle is a first stop surface which interacts with a complementary stop surface of the annular plate in the closed position of the non-return valve. In this closed position, a further, soft and static seal, which is arranged between the annular plate and the annular collar, is compressed to a defined extent. The non-return valve constructed in this manner releases two annular gaps having a considerable flow cross-section, even in the event of low water pressures in the normal flow direction, in such a manner that a very low pressure loss occurs on the non-return valve (Figure 1). <IMAGE>

Title: Method for producing printed-circuit boards
Inventor: KRIEGER FRIEDRICH DIPL ING
IPC: H05K3/42
Filed: 1984-04-03
Abstract: In order to improve the solderability of printed-circuit boards, their conductor tracks are normally coated with tin solder which was briefly in the liquid state during production. In the case of such tinned printed-circuit boards, after a relatively long storage time, difficulties result with respect to the solderability since, as a result of the surface tension of the liquid tin, this is sucked off from the edges of the holes and is drawn into said holes. A sequence of method steps which are known per se is therefore proposed according to the invention, which method steps contain a second masking process but require no remelting or hot tinning for said purpose. <IMAGE>
