Title: Ceramic fibre filter material - wound around alloy steel wire for better tear strength
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D39/08
Filed: 1979-04-07
Abstract: Parent Patent DT 2810937 described a high temp. resistant material for filters, esp. for the sepn. of solids from hot gases or gas mixts. This material consisted of ceramic fibres but such fibres have been found not to have adequate tear strength when the filters are cleaned by shaking or by compressed air backflushing. It is suggested therefore to wind the ceramic fibres around a core of alloy steel wire. This raises the tear strength considerably. The incident gas velocity which is restricted for glass fibres or ceramic tissue to 0.5 m./sec. can now be raised to a multiple of this figure.

Title: Remotely-controlled toy vehicle - uses three conductor layers, one to earth, second to driving voltage and third supplying steering signals
IPC: A63H18/12
Filed: 1980-02-28
Abstract: To enable a child to participate in the control of an electric vehicle meant to move along a roughly prescribed path, three layers of conductors are arranged sideways of the often undulated drive course; one conductor connects to ground potential, a second one to the propulsion voltage, and a third one feeds the steering signals to the vehicle. The vehicle has accordingly three sideways extending sliding contactors. It is the task of the child by properly using the speed and steering controls to enable the vehicle to follow the various curvatures of the supply rails. During a learning process the vehicle will often loose contact with the rails and come to a standstill rather than running over the edge of the table. The difficulty in keeping the vehicle along the intended track is the incentive to play.
