Valve assembly () for fine tuning the temperature of some fluid that has been heated or cooled in a heat exchanging section of a beverage making apparatus (). The valve assembly () comprises a mixing valve (), having a first inlet () for fluid communication with an outlet of the heat exchanging section (), a second inlet () for fluid communication with a source of a hotter or colder version of aforementioned fluid, first and second closing means for altering a flow rate through the first and second inlet respectively, and control means arranged to control the first and second closing means in such way that an increase in flow rate through one of the inlets is matched by a substantially similar sized decrease in flow rate through the other inlet, so that the total flow rate through the mixing valve remains substantially constant.

The power toothbrush includes a toothbrush body and a stem portion extending from the toothbrush body which has a workpiece with a flexible membrane at a remote end thereof, and a flexible membrane at a near end thereof as well. A movable piston is positioned in the stem portion, as well as a fluid which is in communication with the flexible membrane at the workpiece end of the toothbrush and the flexible membrane at the near end of the stem portion. The body includes a solenoid coil which, when actuated, moves the piston in opposing directions in a controlled manner within the stem, which acts on the fluid in the stem and moves the flexible membrane at the workpiece in and out at a desired frequency and amplitude.

A compact gas discharge lamp () comprising four (or more) interconnected tube segments () is provided with an external electrode () that extends at least throughout the length of the tube segments and that is in contact with all tube segments. Several embodiments of the external electrode are disclosed. The external electrode is preferably connected to a node (C) midway between the lamp electrodes, to which end a capacitive divider () is arranged in parallel with the lamp.

Dimmable light generating device

The actuator () of a personal care appliance, such as a toothbrush (), which includes a housing member (), a double E shaped yoke assembly () with two electrical coils () wound around the opposing E shaped sections. An armature () extends adjacent the top of the yoke assembly (), extending beyond the edges thereof. The armature () further includes side portions which extend adjacent the sides of the E shaped yoke (), with each side portion including two spaced magnets which are aligned with the coils () when the actuator () is in a rest position. Power is supplied from a battery source, and a programmable control assembly () applies power to the coils () in a selected manner to produce axial and/or tangential or complex movement of the brushhead workpiece () at the end of an output shaft extending from the armature ().
