Abstract: An antenna device for a portable radiocommunications apparatus, a so-called cell or mobile telephone, has a carrier produced from electrically insulating and non-magnetic material. The carrier is fixable on a circuit card in the mobile telephone and supports a radiator. The radiator has a contactor device for contact with a corresponding contactor device on the circuit card. The carrier has an accommodation space in which an anchorage portion on the circuit card is insertible and fixable. The radiator is disposed on the distal end of the carrier seen from the circuit card.

Abstract: A method is provided for final rinsing in a dish washing machine with clean hot water from a water heater having an elongated standing flow tank which has a cold water inlet with a shut-off valve at the bottom and a hot water outlet at the top and a heating element in the lower part. The temperature of the water is sensed at a location above the lower end of the tank. The shut-off valve is opened for supply of cold water under pressure to the lower end of the tank. Hot water is delivered from the upper end of the tank. The period from opening of the shut-off valve to the time of sensing a temperature decrease in a boundary layer between hot and cold water at the above-mentioned location is measured and on the basis thereof the flow and the period for movement of the boundary layer from this location to a desired position in the tank is calculated.
