Patent DE-2648655-A1 (DE)
Title: Tantalum chip capacitor contacting - by capacitor soldered to pairs of cathode and anode connecting elements on insulating substrate
Inventor: BUB HUBERTUS
IPC: H01G9/012
Filed: 1976-10-27
Abstract: Tantalum chip capacitors for printed circuit boards are contacted by arranging them on one side of a bilaterally copper plated insulating substrate. Pairs of cathode and anode connecting elements on the two sides, which are arranged symmetrically on both sides, are electrically connected. The cathode end of the capacitor is joined to the cathode connecting element and the anode connecting wire to the anode connecting element. Provides less expensive and time-consuming method than encapsulating the capacitor. The mechanical stability of the capacitor is preserved. The planar connecting elements ensure good contacting of the conductor track of the printed circuit board.

Title: Continuous veneering and laminating plant for workpieces - adapts different types of equipment to widely ranging operating conditions
Inventor: FRIZ HELMUT
IPC: B29C63/04
Filed: 1978-03-23
Abstract: An adhesive is applied to one side of a continuously moving band of material, and the adhesive-coated side is pressed against workpieces which are moved at the same speed, in a process for applying ornamental and veneer surfaces to workpieces. After the adhesive has been applied the opposing surface of the band to that coated, is led in direct contact across a heated surface. In the zone of the heated surface, the band of material is held taut and under tension. To ensure that at the moment of the pressing together of the band of material and the workpiece, the adhesive is in the optimal condition for bonding, whilst at the same time the plant allows the widest possible variation in the working parameters.
