Abstract: A washing aid in the form of either a soap tablet or a sponge is covered with a fabric layer formed from spandex yarn. A raschel knit LYCRA.RTM. is stretched over the soap tablet or sponge by firstly manufacturing a tube of the fabric and then injecting the sponge or soap into the tube and sealing the ends of the tube. Heat sealing is used for the transverse seams and heat sealing or sewing can be used for the longitudinal seam of the tube. The apparatus includes an injector, retracting rollers and the heat sealing mechanism.

Abstract: A visual electronic metronome comprises a plurality of LED's arranged in a first V-shaped column and a second column extending downwardly from the top of the V. The LED's are actuated in turn so as to produce the appearance of a block of light moving along the V-shaped column and then down the second column until a leading edge of the block of light reaches the bottom of the column. At that point a strobe light produces a flash indicative of the intended beat. The user can thus observe the approach of the beat and meet it exactly preparing the muscles for playing the instrument according to the visually observed position of the block of light approaching the beat.
