Title: Agricultural machine with two swinging arms - which can be operated simultaneously or separately
Inventor: GENG MANFRED
IPC: A01B73/04
Filed: 1990-07-20
Abstract: The agricultural machine which is mounted on a tractor has equipment mounted on two swinging arms which can be swung to a vertical position in order to reduce the overall width when travelling on a public highway.  The movement of the swinging arms is normally controlled by a flow divider valve (6) which delivers hydraulic fluid to the hydraulic cylinders (1,2) which actuate the swinging arms. When it is required to raise only one of the arms when the machine is operating the flow divider valve (6) is by-passed and each hydraulic cylinder (1) or (2) is controlled by a separate valve (11) or (12).

Title: Microwave cold-start for Diesel engine - vaporises fuel by microwave generatoroperating in relation to engine temp.
Inventor: WOELKY OTTO WERNER
IPC: F02M27/04
Filed: 1990-09-11
Abstract: The atomised diesel fuel is passed into a microwave chamber (4) fitted to the inlet manifold where the fuel is vapourised and mixed with the air.

Inventor: FRIESE KARL-HERMANN DIPL PHYS
IPC: G01N27/406
Filed: 1990-10-12
Abstract: Proposed is a sensing element for broad-band sensors intended for the determination of the  lambda -value of gas mixtures.

Filed: 1991-04-25
Abstract: The resharpening machine has a grinding-wheel assembly (2) with a slide rest (10) displaceable in the direction of the grinding-wheel axis and transversely thereto. Fastened to the slide rest (10) is a tool carrier (12) to which the tool to be resharpened can be fastened.
