Patent DE-4210567-A1 (DE)
Title: Variable valve drive for IC engine - has two tappets connectable by coupling ring
Inventor: EGGERS GERHARD DR
IPC: F01L1/12
Filed: 1992-03-31
Abstract: The variable valve drive is for the lift valves of a combustion engine having an inner tappet (4) and an outer tappet (6) actuated by different cams (5 and 7, 8). A coupling between the two cams having a coupling ring disc (14) and a recess (19) is arranged in the inner tappet. The disc can be displaced by pistons (22, 23) in a guide (26) such that it projects into the recess and thereby couples both tappets, in which case the cams working with the outer tappet are decisive for valve movement. USE/ADVANTAGE - Variable valve drive which avoids pressure medium chambers within the tappets whilst allowing a wide choice of the parameters influencing variability.

Title: Coal-dust main or ignition burner, partic. ejector-staged air eddy burner
Inventor: STROEER KURT DIPL ING
IPC: F23D1/02
Filed: 1992-12-18
Abstract: From an air box (7), prim. air (8) and sec. air (9) are fed to the burner (1).

Title: Method for producing structures which can be soldered in order to make contact with electrical modules
Inventor: HAUSCHILD FRANK-DIETER
IPC: H01L21/60
Filed: 1993-07-22
Abstract: The invention relates to a method for producing metal structures which can be soldered in order to make contact with electrical modules, in the case of which method the structures which are intended for connection to a mother board are arranged flat on the underneath of the module (ball grid arrays). In order to produce the structures which can be soldered, solder paste pads which consist of a solder paste and cover the conductor tracks are applied onto conductor track pads and are melted by subsequently heating them so that the solder paste pads are converted by means of the surface tension of the solder into structures which can be soldered and are formed in the shape of balls to nodules. Conductor track pads with sharp-edged constructions, in conjunction with an intermediate space which surrounds them and is free of solder resist result in the liquid solder balls which are formed during the melting process reliably attaching themselves to the conductor track pads.
