Abstract: A tree stand includes programmable circuitry allowing various messages to be played and lights to be illuminated responsive to actuation of various switches. The various switches are placed on the floor surface adjacent the tree stand and presents are placed over the various switches. Each switch is connected to a programmable control device designed to play a particular message responsive to activation of the switch. The message is designed to be specifically created for the recipient of the present which has been placed on the particular switch which has been activated.

Abstract: There is disclosed a nutsch filter having blades fitted to a central, vertically positioned hollow shaft by a hollow arm, the blades having a plough-like cutting edge and a spatula-like bottom surface acting in the opposite movement direction. A discharge pipe, arranged concentrically to the hollow shaft, is axially displaceable. The discharge pipe is moved upwards against a cover for sealing the filter casing. The filtration or resuspension or drying of the filter cake takes place in this position. In order to discharge the compressed filter cake, the upper edge of the discharge pipe is set by the blades to the level of the paring or skimming process. Paring of the filter cake and conveying of the pared mass into the central discharge pipe opening takes place in a single operation by means of the blades. On drying, hot air or a hot fluid is passed through the cavities of the arm as well as the parts connected thereto.
