Abstract: A solid-particulates-containing composition that can be available ready-made but with a substantial shelf life; in one form it can truly be applied like a conventional paint, and in another form in workable in the manner of a putty. With only a light polishing or burnishing it gives an excellent finish. More specifically, the solid-particulates-containing composition comprises 5-80% by volume of the chosen particulate solid dispersed within either a vinyl acetate polymer product or an acrylic polymer product (or one which is a mixture of the two, with, per 100 volume parts of vinyl acetate polymer product, 5-80 parts of acrylic polymer product), there being, per 100 volume parts of the chosen polymer, from 25 to 80 parts of water.

Abstract: A credit card size portable system comprises a bubble memory for storage serially of digital data, especially of sound analogue signal which has been digitally encoded including, a decoder means for converting the memory output into analogue form, preferably several decoders each for one sound band, a control register for controlling input and output of data from the memory and which is responsive to control data present in the input and output stream, and input and output for the data entering and leaving the card system. The memory can be of 8 megabyte size, which can record 31/2 minutes of music signal. Optical input can be used, with a photoelectric converter at the input. A card is readily programmed with the digital data and can readily be stored or transported for replay of sound signal as desired, in place of conventional discs or cassettes. The control data bits are detected by the control register and serve to control the recording and replay steps.
