An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.

A method to reduce signalling loads in wireless communication networks in a wireless communication network comprising an IMS (IP Multimedia Subsystem) application server allocated on a server by implementing a new voice call terminating procedure. The method comprises determining whether a Mobile Station Roaming Number (MSRN) is related to a foreign network and, based on this determination, performing a number of operations.

Method for terminating voice calls in a wireless communication network

A control arrangement () for an elevator brake, comprises a control circuit () adapted to generate, according to a demand for releasing a first braking member of the elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of the elevator brake, a second actuating signal; a first terminal () for outputting the first actuating signal to a first electromagnetic actuating means () of the elevator brake, a second terminal for outputting the second actuating signal to a second electromagnetic actuating means () of the elevator brake; the control arrangement () being adapted to allow at least the following modes of operation: A) a normal operation mode in which the first and the second actuating signals are supplied synchronously to the first and second electromagnetic actuation means (), respectively, and B) a single braking member test operation mode, in which one of the first and second actuating signals is supplied to the respective one of the first and second electromagnetic actuating means (), and an actuating signal for permanently releasing the respective of the first and second braking members () is supplied to the other one of the first and second electromagnetic actuating means ().

Single brakeshoe test (electrical) for elevators

An elevator machine () includes a machine shaft () and a sheave () that rotates with the machine shaft (). A motor () selectively rotates the machine shaft (). A brake () having at least one brake armature () selectively moves a brake rotor () coupled for rotation with the shaft () between a braking position and a released position. The brake rotor () selectively contacts a braking surface () formed directly on a housing () to resist rotation of the machine shaft ().

Elevator machine with integrated brake surface

An elevator brake () rotor for use in an elevator machine () includes a non-metallic elevator brake hub () and a metal flange (), both of which have an opening with a splined portion for guiding axial movement of the rotor along a rotable shaft (). This arrangement reduces metal-to-metal contact between the rotor and shaft and reduces noise.

A device for securing an end on a load bearing member in an elevator system includes a socket, a wedge and at least one insert member. The socket at least partially receives the insert member and wedge to maintain the end of the load bearing member in position. The preferred arrangement includes two insert members that engage the load bearing member on opposite sides of the wedge such that the load bearing member is gripped between the wedge and the insert members. The insert members and the socket preferably include contoured surfaces that facilitate arranging the engaging surfaces on the inserts in a parallel alignment to most evenly distribute pressure on the load bearing member.

The device is applicable to elevator telescopic two-speed doors, using either two panels with opening towards one side or else using four panels with opening in the center. The rolling device comprises linear ball bearings mounted on a single circular track which together provide a sliding apparatus for the doors. The rolling device further comprises a case for enclosing the sliding apparatus to minimize the intrusion of foreign objects such as dirt and dust.

Roller-track systems for telescopic doors on elevators

The device is applicable to elevator telescopic two-speed doors, using either two panels with opening towards one side or else using four panels with opening in the center, the rolling device being foreseen to be mounted on a single track as a sliding guide. The rolling device includes a case which encloses rollers and counter rollers which roll along the track. The case is formed from two parts connected together and to a bracket on the door by a pair of fasteners. The fasteners form the axles of the rollers. The track can be circular in section and the rollers can be linear ball bearings.

The improvments are applicable to elevator doors and even to doors of vehicles, either made out of two leaves which move in the same direction for the opening and closing thereof, or made out of four leaves each pair of the four leaves opening in the center. The improvements are centered on the use of a single track for both leaves or door panels, a track which may have a rectangular or circular section, located in a box with rolling or movement components which are fastened to the corresponding hanger support of the panel or door. Another improvement consists of the two panels of the door being exactly the same, each one of them including a sound absorbing element. The door frame unit is removable with preassembled active elements so that the same may be transported in a compact, easy manner from the factory to the place of use.
