Title: Protection of data held on shaft card against external reading - has protective layer that can be periodically checked for attempt to read
Inventor: BRUST HANS-DETLEF
IPC: G06K19/07
Filed: 1990-06-11
Abstract: An intelligent data card has a  microprocessor (MP), a data memory (MEM), an interface (CCI) and a coupling unit (K) that provides non contact bidirectional transfer of data. All components are mounted on a substrate that is embedded into plastics. Sensitive data is protected against external access by a protective layer that prevents reading using an electron or laser beam.

Title: Prepn. of sugar-contg. soil improvement agent and erosion protector - by partially hydrolysing ligno-cellulose contg. material, neutralising acids and then pulping or further chipping solids
Inventor: KNAUTH HANS DIPL ING
IPC: C05F11/00
Filed: 1990-07-25
Abstract: The prepn. of a sugar-contg. soil improvement agent and erosion protector made of ligno-cellulose contg. material comprises partially hydrolysing the cellulose and neutralising the acids present. The solids are pulped or formed into chips as required. USE/ADVANTAGE - The prod. has a stable structure and is superior in terms of humus formation and erosion protection compared to conventional composts, peat and peat substits. The fibrous structure causes felting of crumbly humus particles, thus reducing soil erosion. The water storage capacity is higher than peat and compost. Nutrients are bound up in the lignin and thus do not enter the ground water and are slowly given up to the plant roots. The sugar and other soluble components in the hydrolysed lignocellulose activate microorganisms and other small organisms thus leading to an enrichment of the soil with humus. The prepn. of the agent takes approx. 1 hr. Any cellulose-contg. crude material or waste prod. can be used.

Title: Idling speed control for vehicle engine -  has throttle valve stop which is positionally adjusted for cold starting
Inventor: FRANKEN WALTER
IPC: F02M3/07
Filed: 1990-09-18
Abstract: The engine of a motor vehicle is equipped with means to control the idling speed independantly of whether auxiliary equipment, such as air-conditioning equipment, is being driven or not.
