Title: Circuit arrangement for controlling the foreground and background brightness of television display devices
Inventor: BAIER HENRIK
IPC: G09G1/00
Filed: 1982-09-28
Abstract: It is desirable, particularly in data display devices, to be able to adjust the brightness of the characters and graphics displayed, the so-called foreground, independently of the brightness of the background against which the characters are represented. Conversely, the brightness of the foreground should also be adapted when the brightness of the background is adapted to the light conditions or operator requirements. The operator can then set a screen image which is acceptable to him or her. The present invention creates a circuit arrangement which is distinguished by little complexity and allows the foreground and background brightness to be controlled in the desired manner and which can be controlled by means of a microprocessor. For this purpose, a transistor (TS1) of the video amplifier is fed via a constant current source (TS2) which is switched off during the blanking intervals. Main applications of the invention are data display devices. <IMAGE>

Title: Device for reducing the fuel consumption in motor vehicles with spark-ignition engine
Inventor: KURTZ ROLAND
IPC: F02B27/00
Filed: 1982-12-07
Abstract: At higher engine speeds of a motor vehicle spark-ignition engine the intake volume of combustion air increases. This increased air requirement produces a greater drop in pressure on the air filter, which has detrimental effects on the supply of combustion air to the engine. In order to compensate for this fall in pressure at higher speeds of travel, it is proposed to provide a component (4) with an air inlet opening widening in the shape of a funnel for the combustion air, which is connected by way of a hose connection (10) to the air intake pipe (2) of the air filter housing (1) and aligned with its inlet opening towards the oncoming air (12). A considerable reduction in the fuel consumption was noted. <IMAGE>

Title: Process for the production of a casting in a casting mould
Inventor: MUELLER-SPAETH GERHARD
IPC: B22C9/00
Filed: 1983-07-01
Abstract: In the process, a cavity is produced in a mould medium as a part of a mould space for the casting and this mould space is filled with molten metal, a zone influenced by the casting temperature arising in the mould medium around the casting; it is to be made possible that, in particular for the mass production of castings, the use of green sand can be dispensed with and, with a small consumption of mould medium, a simply producible and inexpensive casting mould of sufficient gas permeability results, which moreover ensures a high casting quality with small adverse environmental effects. For this purpose, a chemically bound mould material is used as the mould medium and, after removal of the first casting, that portion of the moulding material is removed which lies in the zone influenced by the casting temperature, after which this zone is filled with mould material to re-produce the mould space before the next casting process.
