Abstract: A method for the production of a capsule shell comprises preparing the capsule shell by electrostatic powder deposition. A plurality of capsule shells may be produced by a process comprising electrostatically applying a powder coating material to a plurality of shaped substrates, treating the powder to form a continuous coating layer on each of the shaped substrates, and removing the shaped coating layers from the substrate to provide hollow capsule shells. An apparatus for the production of a capsule shell includes a substrate, a source of charged powder material and a voltage source for applying a bias voltage between the source of powder material and the substrate to generate an electric field therebetween such that powder material is applied to the substrate.

Abstract: A locating system is disclosed, which can be used for locating a child. The system comprises a child locating device (parent unit) and a further device (child unit) carried or worn by the child. The child unit transmits an electromagnetic signal towards the parent unit, and the parent unit receives the electromagnetic signal, using at least three spaced antennas which are switched in such a way as to obtain a Dopplescant effect. The received signal is processed and the direction of the child unit with respect to the parent unit is displayed on a display on the parent unit. Distance measurement is also possible. The system can be used with several child units.
