Patent DE-2328275-A1 (DE)
Title: Method of producing thermistor beads - involves parallel wires to pick up oxide paste from mould on rod
Inventor: HARKNESS ERIC HAROLD
IPC: H01C7/04
Filed: 1973-06-04
Abstract: Pockets in a mould are filled with a paste of metal oxides from which the beads are to be made. A rod of paste-resistant material, e.g. silicone resin to which the paste sticks, is used to extract the material from the mould, which is then brought down onto two parallel wires spaced closely together. By means of surface tension, a bead is formed between the wires as the rod is withdrawn. A heating and sintering process is then carried out, and finally the parallel wires are cropped to form the component leads. The process is normally extended to simultaneous production of a large number of identical beads, so that the mould is an array of pockets like a waffle iron, and the wires may be a meander line structure.

Title: Separation process for non-ferrous scrap metal - uses a combination of screening, suction, centrifugal and gravitational methods
Inventor: FISCHER REINHARD DR
IPC: B03B9/06
Filed: 1974-04-30
Abstract: The process is applicable to the separation of scrap material from dismantled cars. The scrap is first shredded and the lightest non-magnetic materials such as glass, rubber, wood or plastics are removed by suction. The remaining material is separated by screening into two fractions consisting of pieces either larger or smaller than 20 mm. The larger pieces are then separated by a centrifugal conveyor belt into aluminium, zinc and non-metallic fractions. The smaller pieces are screened again to produce fractions containing pieces either larger or smaller than 5 mm. The final separation is carried out by a gravitational method such as a settling tank, an air settling bed or an air sifting machine.
