Title: Transmission of energy from electrical source without wires - is performed at low frequencies and is based on transformer action
Inventor: DOETSCH HANS PETE
IPC: H05B6/06
Filed: 1974-03-28
Abstract: Energy transfer originates from a push-pull transistor oscillator operating between 5 and 20 KHz supplying a primary winding. This is coupled to a secondary winding via a low loss ferro-magnetic rod core. This in turn couples to the energy receiver which can be in the form of a third winding to feed a fan or similar motor or to a thin ferro-magnetic layer in the base of a vessel requiring heating. This arrangement allows freedom of movement of the energy receiving apparatus such as a plate or ventilator fan without having an exposed hot or electrically live surface or contacts.

Title: Ladies wedge heel shoe - has rubber or plastics bonding uses injection moulding technique to provide strong decorative join
Inventor: SAILER JOSEF
IPC: B29D35/06
Filed: 1974-09-18
Abstract: The wedge heel of the shoe is connected at the bottom to the sole (2) and at the top to the welt (4) and upper (3) by a layer of plastics or rubber which is applied by the injection moulding technique.
