Abstract: A toilet seat and lid, each comprising a rigid insert injection molded of reinforced thermoplastic material. Each insert is then over-molded by injection molding with a thermoplastic elastomeric material which provides the outer surface of seat and lid. The inserts are dimensioned with respect to their over-molded surfaces to be smaller than the finished seat and lid and are designed to give maximum strength to the seat and lid. Each insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The elastomeric material is preferably chemically compatible with the inserts to allow a chemical as well as mechanical bond to take place. The over-molded material provides the desired soft, non-slip, warm to the touch outer characteristics of the seat and lid.

Abstract: A building having a plurality of floors, a plurality of detectors, such as smoke detectors, located on the floors, and an elevator system usable for moving building occupants between floors during an emergency condition, such as a building fire. The elevator system includes a control unit that controls movement of an elevator car between selected floors within an emergency evacuation zone for evacuation of building occupants to a designated evacuation assistance floor. The vertical movement of the elevator car is controlled relative to the dectection of smoke within the building to increase the efficiency of emergency evacuation. The elevator and smoke detection systems are equipped with an emergency power source for operation in the event of a power outage. A signal control system receives status information from the building systems, including the elevator system, an air handling system, and a fire suppression system. The signal control system provides the status information to the fire station or to fire department personnel en route to the building.

Abstract: An apparatus for ensuring proper engagement between connectors in external pneumatic compression devices. Two or more compression bladders are connected via tubing to a controller by a mated connector unit. Each mated connector includes an upstream portion and a downstream portion. The upstream portion includes a shut-off valve per individually addressed bladder. The downstream portion includes structure which defeats or opens the shut-off valve in the upstream connector and allows for fluid flow. Internally and externally, the mated connectors are configured for reciprocal engagement. Even if visual orientation of the connectors fails, the reciprocal structure of the connectors prevents incorrect engagement therebetween.

Abstract: The idea is for a mechanical security system for use as original equipment with the novelty of not adding protective means to the car but removing in a simple manner a fundamental part of the car, the gear stick, thus making it unusable. Hence the possibility of using a mechanical-type security system without the problems of the cost and maintenance of an electronic security system, avoiding the problems inherent in a conventional mechanical security system which necessitates the keeping in the car of heavy, bulky, unattractive-looking objects. Operation of the device: the lever 1 slides inside the base 2 integral with the gearbox proper; the lever is locked, when pushed down, by the arms 3 which spring into their seats when pushed out by the springs 4. The spring 5 ensures soft insertion. The pushbutton 6 allows the lever to be extracted by releasing the arms (which are under tension from the spring 5) via the rod 7. <IMAGE>
