Abstract: Signal transfer devices enable multiple processors to act as drivers or receivers of signals which can transition from an invalid state to a valid state and then return to the invalid state in one clock cycle. The preferred signal transfer device includes a bus line, a plurality of bus drivers electrically connected to the bus line for initiating wired-OR signal transitions and at least one self-timed booster circuit electrically connected to the bus line. The self-timed booster circuit includes a first field effect transistor electrically connected in series between the bus line and a first reference potential and a second field effect transistor electrically connected in series between the bus line and a second reference potential. A timing circuit is also provided as a plurality of inverters which are electrically coupled in series. The timing circuit, which has an input electrically coupled to the bus line, performs a boolean inversion of the signals on the bus line after a first delay.

Abstract: A water-soluble solid beverage cube, consisting of powdered glucose monohydrate, sucrose and hygroscopic flavor material, is prepared by mixing the ingredients, heating them above 95.degree. F in a high humidity atmosphere, shaping the solidified mass and allowing the solid to cool. Additives may be added to the powdered mixture to increase the strength of the solid, improve its hygroscopic nature and alter its taste.
