Dabei befindet sich die Messdrossel für das Stromregelventil (23) in der Hauptleitung (8). Erfindungsgemäss ist die Messdrossel als ein federbelastetes, in Richtung des Lenkzylinders (2) öffnendes Sperrventil mit einer Drossel (11) ausgeführt und die Kräfte der Feder des federbelasteten Sperrventils (11) und der Regelfeder (29) des Stromregelventils (23) sind in zweckmässiger Weise aufeinander abgestimmt.
Patent WO-2004049431-A1 (WO)
Inventor: BRADL STEPHAN
IPC: H01L21/768
Filed: 2003-11-20
Abstract: The invention relates inter alia to a method wherein a contact hole for a conductor (14) is produced in an insulating layer (16). A barrier layer (20) is then applied, followed by a photo-lacquer layer (30) which is applied, irradiated and developed. A galvanic method is subsequently used to produce a copper contact (32) in the contact hole (18). The barrier layer (20) or an additional boundary electrode layer (22) is used as a boundary electrode in the galvanic process. Said method enables critical metal contaminations to be kept to a minimum during manufacturing.

Title: Four-point ball ball bearing - has adjustable pre-stress and variable inner or outer race diameter
Inventor: MUELLER PAUL
IPC: F16C19/16
Filed: 1973-09-19
Abstract: The arrangement concerns mainly a flange-type ball bearing with emphasis on a flat design with a non-clearance lift. The variable diameter design is achieved by means permitting elastic deformation of the races in direction of the shaft centre line. A number of tightening screws are provided to carry out the deformation and variation of diameter. The screws are located on a pitch circle either inside or outside of the ball pitch circle. The deformed race adjusts its shape according to the rigid ring. One alternative provides in the outer race a radial groove to facilitate the deforming process of the ring. Another alternative envisages an outer ring consisting of several parts with an auxiliary ring shaped to result in deformation when tightened.

Patent DE-2359247-A1 (DE)
Title: Electric room heater with liquid resistance - utilises temperature resistance characteristic of electrolyte to achieve self regulation
Inventor: NEUMAYER HANS
IPC: F24C7/00
Filed: 1973-11-28
Abstract: The heater has a casing which acts as a room convector. Two electrodes are brought in through its base through insulating bushes and are connected to the electricity supply through a room thermostat. The casing is filled to a given depth with an electrolyte and the space above the electrolyte provides an expansion volume for the latter. A limiting thermostat is placed within this space and cuts the supply off when the electrolyte reaches its maximum permissible temperature. The temperature of the convector varies with the outdoor temperature and the conductivity of the electrolyte thus adjusts automatically to keep the power input equal to the actual room heat loss.
