Title: Fail-safe ignition and steering lock - with spring loaded cam between lock barrel and bolt
Inventor: LIMBURG JOACHIM
IPC: B60R25/021
Filed: 1974-03-28

Title: Conducting inlay in flooring for electrostatic discharge - consists of woven layer incorporating metallic conducting element with suitable earthed surround
Inventor: PETRI ROLF
IPC: H05F3/02
Filed: 1974-09-25
Abstract: Flooring in buildings is protected from building up electrostatic charge, and there is a guaranteed maximum resistance to earth at any point in the flooring. The system represents an improvement on other methods such as using layers of conducting material which give a different resistance to earth at different points in the flooring, possibly above the upper limit required. In the method proposed here, a woven layer of polyamide or polyacryl based material (2), in which an unshielded copper strip (1) is incorporated, is embodied as a layer in the flooring below the top surface (5) but above the base layer (6). The metal strip is clamped to an earthing strip (3) at suitable points. This arrangement allows the floor to be constructed with a smoother surface and with the required electrical properties.

Title: Utilising waste heat from e.g. power stations - for methanol dissociation giving prods for use in heating systems
Inventor: FALKENHAIN GERD DR
IPC: F24V30/00
Filed: 1974-10-08
Abstract: Utilisation of low temperature waste heat from e.g. power stations employs a heat pump, for application in district heating systems, etc. The available heat in the fuel is used initially for electric power generation. The waste low temperature heat is used for catalytic dissociation of methanol into carbon monoxide and hydrogen mixt.
