Abstract: A synthetic fiber cable, preferably of polyamide material, consists of a bundle of load-bearing synthetic material fibers and at least one conductive temperature sensor element extending a length of the cable. The temperature sensor element forms, in dependence on the temperature, a conductive connection over the length of the cable, which connection is constantly monitored by a measurement circuit. The connection is interrupted at a checking circuit in the case of temperatures critical for the synthetic fiber cable. The temperature sensor element can be a fine wire melting at the critical temperature. The synthetic fiber cable can be used in elevator installations amongst other things as a safety device, especially as a fire alarm.

Abstract: Equipment for generation of shaft information, including transmitter elements of a elevator shaft arranged at the back part of a frame of a story door. Opposite the transmitter elements switchable transmitters are arranged at the back part of a frame of a cage door. Mounting time and costs are substantially reduced by the arrangement of the transmitter elements and transmitters at existing components.

Abstract: A system for monitoring an elevator door in a hoistway. The elevator door is movable between a closed position and an open position. The system includes a transmitter for emitting an optical signal and an interlock device for latching the elevator door. The interlock device includes an optical nosepiece so positioned for receiving, guiding, and outputting the optical signal from the transmitter when the elevator door is closed and the interlock device is in the latched state. A receiver receives the optical signal via the nosepiece only when the elevator door is closed and the interlock is latched to thereby indicate the elevator door is in its latched state.

Abstract: This device allows an implicit or explicit input of destination calls on elevator installations. After a corresponding inquiry by a detector, an information transmitter transmits data. This data can contain direct information about the desired destination floor and/or serve as identification of the elevator user and thereby enable access to information about the destination floor which is stored in a memory. The memory is contained in a processing unit of an elevator control. Communication between the detector and the information transmitter takes place, for example, without contact. Using the received data the destination floor is evaluated in the processing unit and communicated to the elevator control. The assignment is communicated to the passenger on a display. The process of inputting a call takes place automatically and independent of the orientation of the information transmitter.

The door panel has a front and back wall which are connected together by a first connection which is releasable under the action of heat and has at least a second heat-resistant connection.

Abstract: An apparatus for synchronizing a telescopic ram in a hydraulic elevator in which two or more pistons and a cylinder are simultaneously extended from and retracted into a foot portion mounted at the bottom of an elevator shaft includes a connecting cable which is fixed on one end to the shaft wall and on the other to one of the pistons and the cylinder and is deflected over a roller used for the synchronization. The connecting cable is a sheathed synthetic fiber cable.

Abstract: A traction sheave for driving synthetic fiber ropes, preferably of an elevator installation, ensures a consistently good selected tractive capacity that is largely independent of external influences which reduce friction. At least part of the rope running surface on the traction sheave is provided with a selected roughness grade of N7 to N12. The selected roughness grade on the running surface is formed either by mechanical machining or by use of a suitable coating, preferably a plasma coating of corundum. For example, only the bed of the rope groove, the area of the flanks of the rope groove, or a wide area of the surface of the rope groove can be of the selected roughness grade. By correspondingly suitable arrangement of these differently formed rope grooves on the traction sheave, a desired tractive behavior can be systematically effected.

Abstract: A drive unit has a traction sheave mounted on an end of a drive shaft supported by a bearing that is mounted on an extension of a bearing plate that is part of the motor casing. The traction sheave has an extension that serves as a brake drum. Mounted between the traction sheave and the casing, the brake drum together with first brake arms, second brake arms, first electromagnets, second electromagnets, first compression springs and second compression springs form the braking device of the drive unit. On a top of the bearing plate is a first arm linkage and at the bottom of the bearing plate is a second arm linkage. The force of the first compression spring is transmitted to the brake drum by the first brake arm, the required friction force on the brake drum being generated by a first brake lining mounted on a first brake shoe. The friction force on the second half of the brake is generated analogously.

Abstract: An elevator installation having a system of making payments so that the installation can be operated as a means of transport for providing chargeable transportation services for persons and/or goods. Also provided is an identification device for recognition of types of cashless payment, a calculation device for cashless calculation of transportation services to, for example, trip destinations input within a time window, and a charging device for cashless debiting of the costs of transportation services. The identification device can recognize different types of cashless payment such as tokens, tokens with electronic chips, prepayment cards, cards or keys with data carriers, or transmitter/receiver systems or biometric systems with individual data of the user. The charging for transportation services can, for example, take place in relation to operations-specific and/or user-specific criteria.

Abstract: A roller degradation monitor device monitors the diameter of escalator rollers during operation of the escalator. A cam plate is mounted proximate the roller track for sequential contact with the upper circumference of rollers as they travel along the track. The vertical displacement of the cam plate is monitored by a proximity switch or sensor, differences in cam plate practice from an established baseline signifying variations in roller diameter. The output of the proximity switch or sensor provides a continuous measure of wear and decrease in diameter of the rollers. When the wear exceeds a predetermined value an alarm can be actuated.

Abstract: A sheathed synthetic fiber rope includes concentric layers of load-bearing synthetic fiber strands, preferably of aramide fibers, with an outermost layer of strands having anchoring strands permanently fastened to a sheath extruded onto the outermost layer. The anchoring strands can be formed of weldable or vulcanizable material. Alternatively, a polyurethane jacket surrounding each of the outermost layer strands can be used to permanently fasten the sheath.

Abstract: A synthetic fiber rope having load-bearing aramide fiber strands laid together in parallel in concentric layers of strands and an intersheath with sheath surfaces adapted to the external contours of the adjacent layers of strands. By positively bonding the inner and outer layers of strands a higher torsional rigidity is achieved as well as a rope structure of the stranded rope which is less susceptible to twisting. Furthermore, the elastic intersheath between the layers of stands serves to protect the strands against abrasion and assists in transmitting torque within the rope over a large area.

Abstract: An apparatus for reducing wind noises on elevator cars traveling at high speed includes domes with an aerodynamically favorable shape that are attached above the car roof and/or under the car floor. The domes are made of a flexible material attached over a supporting frame of rods or tubular air chambers. Closable openings in the dome walls permit evacuation of passengers and access to the car roof and the underside of the car.

Abstract: A braking device for load carrying cars in vertical conveyor installations with elastic suspension apparatus holds fast to guiderails to prevent vertical displacements and vertical vibrations while stopped at landings. The braking device contains integrated sensors for registering the holding forces occurring between the load carrying car and the guiderails. Before travel of the car continues, the signals from these sensors enable a drive regulator to adjust via a drive unit the tensile force in the suspension apparatus carrying the car in such a manner that the braking device is relieved and can be opened without generating a jerk on the load carrying car.

Abstract: A rope has a rope core formed of load-bearing aramide fiber strands laid parallel to each other in concentric layers of strands and strands of an outermost layer laid with opposite lay to the rope core. As a result of the opposite lay, the torques which occur in the layers of strands when under load cancel each other out and a non-twisting rope structure is achieved. An elastic intersheath is positioned between the oppositely laid layers of strands to protect the strands against abrasion and to transmit the torque over a wide area in the rope.

Abstract: A user communicates travel destinations to a transportation system utilizing a human-machine interface having a touch screen with a selection of designations that can be individually selected by touching the screen. For example, a selected designation “Library” is communicated from the human-machine interface to a transportation system control without the user knowing where the library is actually located. The control determines the real locational parameter of the travel destination from a table storage device containing the designations and the associated real locational parameters. The control assigns the desired travel destination, such as a floor, to vehicle, such as an elevator car, with the best travel conditions and informs the user of the assigned vehicle on the touch screen. The information displayed to the user can include a vehicle identification, a travel destination identification, instructions and an indication of the place of boarding.

Abstract: An auxiliary device for displacing a payload receptacle, which stands outside a station, into one of the stations. The auxiliary device includes a temporarily activatable brake release device for releasing the braking device and an auxiliary drive device for displacing the payload receptacle when the brake release device is activated. The brake release device and the auxiliary drive device are arranged in the uppermost region of the elevator shaft and are actuable by way of a crank rod linkage. The crank rod linkage includes a lower actuating end, which can be brought from a rest setting into a working setting. The crank rod linkage is coupled with a rod linkage extension, the vertical effective length of which corresponds with at least the vertical spacing of the walk areas of two adjacent stations.

Abstract: The auxiliary device is needed when the elevator stands in the elevator shaft outside a station. The auxiliary device includes an auxiliary drive device for the payload receptacle. For sight-free observation of the auxiliary device there is arranged an image transmission device, which includes a sensor, a display device and a transfer path. The sensor serves for detection of images which illustrate a drive pulley coupled with the auxiliary drive device. The display device serves for visualization of the images detected by the sensor, and the transfer path serves for transmission of the images detected by the sensor to the display device.

Abstract: A torque-measuring device for an elevator brake measures the elastic deformation of active parts of a brake, for example, a shoe brake. In that case, regions with a reduced bending moment resistance are formed at the brake levers and elastically deform under the action of braking torque. The elastic deformation is detected by strain gauge strips arranged in these regions and connected as a measuring bridge and the generated voltage signals are provided to an elevator control as reference signals by an analog-to-digital converter and a microprocessor. The elevator control uses these reference signals to generate in a drive motor a motor torque compensating for the measured torque before the release of the brake. Thus, the resulting torque at the brake shaft is zero and a jerk-free start of the elevator car, without a torque jump, results therefrom after release of the brake.
