An embodiment of the invention is directed to a system having a pulley attached to a building. A closed loop of cable is installed around the pulley. The loop is of sufficient length so as to reach, when deployed outside of the building, below the pulley to where emergency personnel gather in an area next to a base of the building (when responding to a disaster situation in the building). A winch around which the loop is to be operatively installed is located in the area next to the base. Other embodiments are also described and claimed.

Elevator cars move in two vertical hoistways each having at least one crossing-point to a third vertical parking hoistway arranged between the two hoistways to allow transfer of the elevator cars between adjacent ones of the hoistways. A control system and a drive move empty elevator cars through the crossing-points for parking and for responding to calls for service.

A workstation having an adjustable support structure is disclosed. The workstation includes a beam, a position locking apparatus, and a workpiece-supporting device slideable along the beam to a position where it is locked by the locking apparatus. The locking apparatus is configured to exert a constraining force proportional to a load force. Also disclosed is a workstation including a means for supporting a workpiece, a means for supporting a means for supporting the workpiece at a selected distance above a floor, and a means for frictionally securing the means for supporting the workpiece to the means for supporting the means for supporting the workpiece. Also disclosed is a workstation including a vertically disposed support member and at least one tooling plate assembly including a position securing apparatus for securing the tooling plate assembly in a selected vertical position and including wedging surfaces cooperating in frictionally securing the tooling plate assembly to the support member, wherein the securing force corresponds to the loading force.

Rapid deployment of a suspension cable is a supportive system to several high-rise building rescue methods. A cable is pre-attached in a peelable manner to the building side and rigidly attached to the building top. An emergency chase vehicle is dispatched to the building base, attaches to the lower end of the cable and then moves away from the building. The cable peels off the building and suspends from the building top to the ground at approximately a 45 degree angle. A high-rise building rescue method now utilizes this deployed suspension cable.

A system for mechanically lowering a load from an elevated position to a lower position in a relatively slow and controlled manner using only gravity and frictional forces. The system includes a vertically aligned glide rod, a glide collar that moves longitudinally over the glide rod, two vertically mounted friction rods mounted on opposite sides of the glide rod, a friction collar that moves longitudinally along each friction rod, and a support platform coupled to each friction collar and to the glide collar. The glide rod includes spiral vane along its entire length upon which the glide collar rides when a load is placed on the support platform, allowing the support platform to descend at a safe speed via gravity. The friction rod and collars are used to move the support platform from a stored position located above the elevated loading position to a lower position so that a load may be placed onto the support platform and to stabilize the support platform as it descends from the loading position to the ground.

A system for the application of an image to an upper surface of a built structure, the image arranged for visibility from over-flying craft. An upper surface of a built structure incorporating indicia thereon or therein; the indicia constructed so as to be discernable by observers in craft passing over the built structure when the craft is within a predetermined legibility distance of the built structure.

A roping or belt assembly in an elevator system includes at least one load bearing member that is covered using a urethane coating. The urethane coating does not contain any waxes. The absence of the waxes, which are otherwise typically included in urethane coatings, ensures better friction characteristics in elevator system operation.

A display having mating door sections includes a frame, upper and lower parallel, spaced apart door mounts affixed to the frame, and doors mounted to the frame between the door mounts for securing panels thereto. The door mounts each include openings in vertical alignment with one another for mounting the doors. Each door is mounted to the display frame, between the upper and lower door mounts. Each door has first and second mating door sections joined to one another at a mating juncture. The mating door sections each have a raised rim around a rear portion and upper and lower edges of the sections defining a central recessed region. The recessed region has a plurality of apertures therein, each defining a raised sleeve portion and an opening therein. Each door includes upper and lower pivot pins at about the rear portion at the upper and lower rims respectively. The pivot pins extend transversely from the upper and lower rims and are configured for insertion into the door mount openings for pivotal movement of the doors. The doors are removable from between the upper and lower door mounts. The door sections recessed regions are each configured for mounting an associated panel thereto. Each associated panel resides within the recessed region below the door section raised rims.
摘要:
A double deck elevator comprising an upper cage and a lower cage vertically movable together in a hositway, wherein a space between the upper cage and the lower cage is covered by covers. The covers guide airflow flowing around the space to reduce air turbulence noise, and consequently the quietness and comfortableness in the cages is improved.
