Patent DE-4340588-A1 (DE)
Title: Prosthetic device for lifting and lowering handicapped user
Inventor: KAUFFMANN RICARDO M DR
IPC: A61G5/14
Filed: 1993-11-29
Abstract: The prosthetic device has a base, a seat for seating the user in a normal sitting position and an upper body support engageable with the user's upper body. Seat and upper body support positioning devices include a power operated lifter on the base for elevating and lowering the seat and upper body support between user standing positions and user seating positions. In the user standing positions, the upper body support is elevated above the base an appropriate distance to engage the user's body in a certain supporting relation above the waist in such a way as to support the user in an upright standing position. The seat is retracted to enable the user to assume this standing position. In the user seating positions, the seat is extended horizontally to seat the user in a normal sitting position. The upper body support is lowered relative to the base to engage the user's body in the supporting relation above the waist to support the user's upper body in the sitting position. The lifter is selectively operable in raising and lowering modes by user actuators which are easily accessible throughout the range of adjustment of the prosthetic device between and including its user standing and user seating configurations.

Patent DE-4343003-A1 (DE)
Inventor: KARSCH ULRICH DR
IPC: B29C49/46
Filed: 1993-12-16
Abstract: The invention relates to a method for producing hollow objects made of thermoplastic materials, the walls of which are subjected to a treatment with a fluorine-containing gas mixture for the purpose of influencing the permeation properties. The method can be used in particular for fuel tanks in order to reduce the permeability of their walls, in particular irrespective of the alcohol content of the fuel. In this case, two treatment steps are provided, the first of which works with a gas mixture which contains fluorine and oxygen. In a second treatment step, following later, a gas mixture which contains fluorine but is free from oxygen is used.
Patent DE-4344633-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: F02D41/22
Filed: 1993-12-24
Abstract: A system for the determination of loading with diagnostics for an internal combustion engine, in which the filtered main load signal and the secondary load signal, which is also filtered, are evaluated to form the load signal necessary for the regulation of an internal combustion engine is characterized by signal limitations being imposed on the main load signal in both full-load operation and part load operation or idle running, and the main load signal being monitored for plausibility with a secondary load signal in the range excluding return flow. In the event of an implausible main load signal, the load signal will only be derived from the secondary load signal. A number of correction factors are taken into consideration for plausibility checks, so that the maximum and minimum values can be modified to the prevailing conditions as is appropriate. Furthermore, the signal from the lambda probe may be used for plausibility checking.

Title: Data reproduction method using video-recorder with inbuilt time switch
Inventor: DECKER CLEMENS
IPC: G04G15/00
Filed: 1994-03-08
Abstract: The method involves applying stored data in analogue or digital form in a microprocessor (MP). The stored data can be reproduced as melodies or as speech.
