Title: Information device for a motor vehicle
Inventor: KNOLL PETER PROF
IPC: H04M1/27475
Filed: 1988-12-16
Abstract: An information device for a motor vehicle is proposed in which the information which is important for a driver is output on a screen. The information device has a monitor in which the screen is divided into a plurality of areas arranged one on top of the other. The individual areas are assigned to fixed functions, which permits the representation and control of the devices connected to the information system to be well organised and simple. Thus, for example in the device selection area, the desired electrical devices such as radio or telephone, air-conditioning system or a location and navigation system are selected. In the operation area arranged at a higher level, the individual operations are represented and in the protocol area located at the top the information which is important for the driver is represented. The division of the screen into three components ensures a particularly clear representation of information. Cursor keys are provided as the data input unit and by means of selection menus using dialogue communication simplify the control of the individual devices. <IMAGE>

Title: Combination water meter for large and small flows - has changeover valve for Woltmann meter and auxiliary meter operated according to flow rate
Inventor: DEWALD HANS-PETER
IPC: G01F15/00
Filed: 1989-09-05
Abstract: A Woltmann meter (1) is used as the main meter to ascertain the larger flow. An auxiliary meter (3) in a neighbouring line (2) at the side of the main meter measures the smaller flow.

The closure piece of the valve is slidable along the length axis of the valve by means of a central glide bolt. The closure force is provided by a magnetic stopper and a pretensioned pressure spring. The opening force is created by the pressure difference between the pressure of the steady water in the main meter and the low pressure arising from flow through the auxiliary meter. ADVANTAGE - By simple means, change-over valve operates automatically without outside help and without giving rise to measuring errors.

Patent DE-3933728-A1 (DE)
IPC: B30B15/00
Filed: 1989-10-09
Abstract: An air spring for disposition between first and second parts of a machine, e.g. a press frame and ram, comprises a base (36) adapted for attachment to one of said parts (eg the frame) and a plurality of open ended longitudinally extendable resilient members (38, 44, 48) stacked one above the other. Each of the members is interconnected to an adjacent member to allow air to flow from one to the other. The outer members (38, 48) are connected, respectively, to the base (36) and a pipe (52) for attachment to the other part (e.g. the ram). An elongate guide (40) is connected to at least one of the members (38, 44) to limit movement of that member in a direction transverse to the length of the guide. One member (48) has one end not connected to the guide (40) but rather that end is free to move in all directions relative to the guide to allow reciprocation between the parts without the air spring creating extraneous loading on the first and second parts because of improper alignment between the first and seconds parts and the air spring. A conduit (68) connects the interiors of the members to a large tank. <IMAGE>
