Abstract: The present invention is directed to a method for stabilizing the flavor of a fermented malt beverage, most particularly a beer, by the addition of one or more inhibitors, blockers, reducing agents or binding agents that inactivate one or more Maillard reaction intermediates that induce staling of the flavor of fermented malt beverages. In preferred such methods, the agents used are reductase enzymes, especially aldehyde reductases, carbonyl reductases, aldose reductases, oxoaldehyde reductases and most particularly oxidoreductases such as isozymes of Old Yellow Enzyme (OYE;EC 1.6.99.1) (e.g., OYE1 and OYE2 and OYE3). The invention is also directed to the fermented malt beverage prepared by such a method, and to the use during the brewing process of reductase enzymes from naturally occurring sources, including those produced by yeasts, to stabilize the flavor of the resulting beer product and to produce a beer having a stable flavor.

A spring-supporting post is formed on the inner face of the outlet cover and projecting therefrom such that the spring member fits within facing inner sides of the first and second shield portions so that the first and second shields completely block external access to the rectangular slot openings and grounding pin opening of the outlet cover.

Abstract: A computer system with a number of subsystems or modules on separate circuit boards employs electronic keying to ensure proper configuration of these boards. A power key arrangement associated with a plug-in connector enables a separate power supply for each set of boards. A power supply turn-on signal is routed through a uniquely-configured connector path for each board, so the power supply turn-on is inhibited for improper configurations. The uniquely-configured connector path may use either a series or a parallel implementation. The series implementation employs a set of diodes connected for conduction in either of two directions, with the mating connector having its conductor paths connected to match the diode configuration; in this manner, the power supply enable signal can only flow through the series path if the proper board is plugged into a properly-coded slot, in which case the power supply to activate this board is activated through the series path including the diodes.

Abstract: A battery sensor for measuring the state of charge, temperature and electrolyte level of a battery. The state of charge is determined by a concentration cell. The concentration cell comprises an ionic fluid of known concentration separated from the electrolyte by an ionically porous plug. When a first electrode is placed in the electrolyte and a second electrode is placed in the fluid, a voltage, which is a function of the difference in the concentration of each, is generated so that a state of charge of the electrolyte may be determined. Temperature determination is made by positioning thermistors above the electrolyte thereby measuring the gas temperature over the aqueous electrolyte. By positioning one of the thermistors in contact with a catalyst for recombining the gaseous hydrogen, produced by a fully charged battery, with oxygen, sensing means are established for indicating an overcharge situation.
