Title: Method for compensation for the starting friction of a drive
Inventor: GRIMM WOLFGANG
IPC: G05B19/19
Filed: 1995-10-27
Abstract: A method is proposed for determination of a starting friction compensation signal (FK) for compensation for the starting friction in a drive. It is connected to the drive control signal when the movement of the drive starts from a stationary position. According to the method, the compensation signal (FK) is composed of an initialization compensation signal (Ko, Knew) and a correction signal ( DELTA K) which is formed by linking at least two characteristic variables (TR, SR) which describe the starting friction. The determination of the correction signal ( DELTA K) includes the following steps in this case:   - determination of association values (zero, small, medium, large) for the characteristic variables (TR, SR) to form predefined association functions which describe the characteristic variables linguistically, - linking of the determined association values (zero, small, medium, large) in accordance with a predetermined control procedure to form proposed values ( DELTA F/Fo) - linking of the proposed values ( DELTA F/Fo) in accordance with a predetermined algorithm to form the correction signal ( DELTA K).

Title: Improvements in or relating to meters
Inventor: FOSTER STEPHEN LESLIE
IPC: G05D16/06
Filed: 1996-01-04
Abstract: The meter 2, e.g. a gas meter includes an inlet boss 4 providing an unregulated supply of gas via a valve means 8 which regulates the flow of gas as it passes into a chamber 6. The valve means 8 forms part of a governor which is formed integral with the gas meter. The valve means 8 includes a valve stem 12 which has a bore 18 extending throughout the length of the valve stem. The valve stem passes through the chamber 6 and through a first diaphragm 22 to which it is sealably connected and is terminated on the surface of second diaphragm 34. The first diaphragm 22 separates second and third chambers 24, 28, the second chamber 24 being in communication with the first chamber 6. The third chamber 28 is connected via the bore 18 in the valve stem 12 to the unregulated gas supply. The second diaphragm 34 separates fourth and fifth chambers 32,38, the chamber 38 is vented to the atmosphere. In normal operation the chamber 32 is connected by a control valve 46 to the chamber 6, and the various balance of forces through the governor allow the gas supply to be regulated. The control valve 46 when operated by a solenoid 48 into a second position causes the chamber 32 to be connected to the chamber 28 and the inlet pressure is communicated via the conduit 54, 50 to the chamber 32 causing the governor to shut off the gas supply. <IMAGE>

Patent GB-2302942-A (GB)
Title: Air-conditioning system for motor vehicles
Inventor: SCHREIBER ROLAND
IPC: B60H1/32
Filed: 1996-07-03
Abstract: An air-conditioning system for motor vehicles has a compressor 11, a condenser 12, an expansion valve 13 and a vaporizer 14, through which a coolant flows in a coolant circuit 15 in the aforementioned sequence. An air distributor duct 16 which leads to the passenger compartment and in which the vaporizer 14 is arranged can be supplied with an airstream. The airstream can be set either to fresh-air supply or to air-circulation mode by actuation of a servo-controlled flap 18. Since a hydrocarbon which is environmentally acceptable but inflammable is to be used as coolant, for safety reasons a pressure sensor 35 for detecting the coolant pressure in the region of the vaporizer 14 is arranged between the vaporiser 14 and the expansion valve 13 of the coolant circuit. In the event of the coolant pressure dropping below a presettable, minimum acceptable limit value, the said pressure sensor 35 produces a pressure signal which, if appropriate, sets the flap control for the airstream to fresh-air supply and activates the corresponding blower 17 and an optical and/or audible warning device 32.

IPC: B60J3/02
Filed: 1998-03-05
Abstract: The sun visor 1 is mounted adjacent to the vehicle's front windscreen by a ball joint which allows multi-axis rotation of the visor about the joint. The joint has a ball 6 attached to the vehicle by a rigid mounting 5 and a cup 2 which is attached to the visor by a rigid mounting 3.
