  • Patent number: 5495725
    Abstract: A water transport system replaces the inverted water bottle on a conventional bottled water cooler of the type with a refrigerated, open top water reservoir. The system automatically transfers water from an upright water bottle below the reservoir into the reservoir whenever water in in the reservoir falls below a predetermined level. A water pipe carries water from the bottle, through a sealed closure in the bottle neck and up into the reservoir whenever air pressure in the bottle is elevated. An air pump in a housing atop the reservoir generates air pressure in an air tube passing through the closure and into the bottle. A water level sensor reduces air pressure in the system when the water in the reservoir reaches a predetermined level to thereby automatically control refilling of the reservoir.

  • Patent number: 4644104
    Abstract: The present invention is directed towards a security system for a multi-unit facility such as a hotel wherein access to each unit or room is accomplished through a door structure or like closure which incorporates a separate locking assembly. The locking facility is of the keyless entry type wherein a preset code is fed into an electronically controlled lock through a plurality of finger operated switches (fingerboard) for authorized entry. Each of the actuating facilities associated with each closure is capable of having a stored preset code changed through operation of a microprocessor. Telephone lines interconnect the activating and locking facilities associated with each room to a central control facility, for example, in the office of a hotel.
