Abstract: A lockable electrical strip includes a power outlet strip base with a plurality of electrical outlet sockets on the top of said base, one or more locking rings, one or more enclosing walls, and a locking piece. A lockable power outlet strip includes a power outlet strip base having one or more power sockets and a power cord connectable to a standard power supply; one or more enclosing walls connected to said base which enclose the power strip base; locking rings connected to said enclosing walls; and a locking piece insertable through said locking rings to prohibit the enclosing walls from opening.

Abstract: A point of play terminal includes a lockable outlet strip having one or more power sockets and an source of electric power, wherein the sockets can be selectively enabled with power, a computing device in electronic communication with said strip, wherein the computing device selectively enables power to individual sockets, and an access terminal in electronic communication with said computing device. A computer software driven process for allocating duration of allowed power use for individual power sockets based on identification data. An apparatus for allocating duration of allowed power use for individual power sockets based on identification data. An article including: a storage medium, the storage medium having instructions stored thereon for allocating duration of allowed power use for individual power sockets based on identification data, one or more enclosing walls, and a locking bar.

Abstract: A dispersion of a polyurea in an aromatic polyisocyanate is prepared by mixing the polyisocyanate with one or more aliphatic diprimary diamines having (a) at least one amine group attached to a carbon atom having not more than one hydrogen atom attached thereto or (b) at least one amine group attached to a carbon atom which is itself attached to a carbon atom having not more than one hydrogen atom attached thereto, provided that both amine groups are not attached directly to separate rings of an alkylene-linked polycyclic aliphatic ring system. The reaction preferably takes place at a temperature in the range 20.degree. C. to 60.degree. C. The polyurea dispersion products are useful for manufacture of polyurethane foams and elastomers of superior physical properties.
