Patent DE-4233247-A1 (DE)
IPC: A61F2/64
Filed: 1992-10-02
Abstract: The invention relates to a swing phase control device for an artificial knee joint prosthesis facilitating a natural sequence of movements and capable of reacting to abrupt movements. The swing phase control device consists of a piston and cylinder arrangement (2). There is a first chamber (8) on one side of the piston (12) and a second chamber (17) on the other. Both chambers can be interconnected via a first choke (38, 43). There is a second choke on the outlet side of the second chamber (17) which connects the latter to a fluid tank. The pressure in the second chamber (17) is applied to a control piston. It is designed in such a way that the second choke (32) closes when the pressure in the second chamber (17) reaches a predetermined level. Once the second choke (32) has closed, the elastic pressure in the second chamber (17) reinforces the return movement of the piston (12) in the cylinder, facilitating an abrupt stretching of the leg.

The gas is released through a port (9) from the cylinder (7). USE/ADVANTAGE - Also for unbolting doors in situations of danger, e.g. fires. More compact and less costly device operates more rapidly and requires only small spring or source of electric current.

Title: Process for the preparation of 4-nitrotoluene-2-sulphonic acid
Inventor: MUELLER WOLFGANG DR
IPC: C07C303/06
Filed: 1993-04-06
Abstract: In the known processes, an explosive decomposition of the reaction mixture can occur due to exceeding of the temperature during the reaction. Processes in which sulphur dioxide is used as a solvent additionally require an increased outlay in terms of apparatus. The novel process is intended to be environmentally compatible and safe to control, and to afford high yields. The novel process consists in alternately adding dropwise p-nitrotoluene dissolved in dichloroethane and, per mole of p-nitrotoluene, 1.6 mol of sulphur trioxide in portions into dichloroethane initially introduced as a solvent, raising the temperature to 75 DEG C to 80 DEG C, after about 45 minutes adding 0.4 mol of sulphur trioxide per mole of p-nitrotoluene, stirring at the abovementioned temperature for about 75 minutes and working up the reaction solution. The process is used for the preparation of 4-nitrotoluene- 2-sulphonic acid, which is employed e.g. as a starting material for the production of 4,4'-diaminostilbene-2,2'-disulphonic acid and of 4-aminotoluene-2-sulphonic acid, which are important in the preparation of dyestuffs.
Patent DE-4314259-A1 (DE)
Inventor: ROESCH GERHARD
IPC: H05K3/42
Filed: 1993-04-30
Abstract: The invention pertains to a process for throughplating of printed circuit boards using conductive plastics for direct plating, wherein a polymer film with intrinsically electrical conductivity is adhesively deposited on nonconductive areas of the printed circuit boards, whereupon a metal film is applied. Selective production of the polymer film has previously been seen as requiring an oxidative pretreatment of the printed circuit board, though this can negatively affect the further course of the process. With the present invention the potential negative effects are avoided by forgoing the oxidative pretreatment.
