| 221 | Device for detecting and localizing a fault in an aerial rope-way transport installation | US781726 | 1985-09-30 | US4697169A | 1987-09-29 | Jean-Jacques Bertrand |
| A safety line 20 of an aerial ropeway transport installation 10 comprises in one of the stations a safety generating unit 22, which emits a square wave AC signal on the line.In the opposite station the line 20 is earthed by means of a diode 24. The safety generating unit 22 includes a measuring device of the positive and negative voltages at the line terminals to distinguish between a line break and a line short-circuit.A localizer indicates the location of the fault. | ||||||
| 222 | Clamping device with test spring deformation measurement | US740070 | 1985-05-14 | US4686906A | 1987-08-18 | Bernd Meindl |
| Device for continuously controlling the clamping force in monocable ropew, comprising a test spring which acts against the pressure spring and which is arranged with the latter-mentioned in the pressure mechanism. A signal and/or stop device is responsive to a deformation of the test spring when a predetermined threshold magnitude of deformation has been exceeded. | ||||||
| 223 | Magnetic testing device for supported objects | US394761 | 1982-07-02 | US4546316A | 1985-10-08 | John G. Lang |
| The present invention relates to a testing device for magnetically testing while uninterruptedly moving along an elongated magnetically permeable object having intermittent supports to one side thereof. The device which is arranged to close around the test the object from all sides other than at the supports and to open at and clear past the supports while continuing to move, comprises first and second housing sections hingedly connected to one another with the first housing section being adapted to maintain the device in a testing position relative to the object and the second housing section being moveable relative to the first housing section for opening and closing the device around the object. An actuator is provided for effecting such opening and closing with a control for operation of the actuator without manual assistance at the device. | ||||||
| 224 | Rocker arm assembly for an aerial tramway | US346167 | 1982-02-05 | US4462314A | 1984-07-31 | Jan K. Kunczynski |
| A rocker arm assembly for support of the haul rope of an aerial tramway or the like is disclosed. The assembly includes rocker arms, rope supporting sheaves rotatably mounted to the rocker arms and cantilevered from an inwardly facing side of the rocker arms. The rocker arms are additionally formed with rope catching groove or recess positioned outwardly of the sheaves and having a configuration which will enable not only the rope, but a hanger arm and grip to pass over the rope catcher in the event that the haul rope derails from the sheaves. The rocker arm assembly also preferably includes a platform which acts as a mount for the rocker arms and can be used for maintainence and repair of the rocker arms and rope supporting sheaves. Additionally, the rocker arm assembly includes haul rope derailment responsive apparatus formed to shutdown the tramway operation upon derailment of the rope from the sheaves. | ||||||
| 225 | Safety device for a rocker of sheaves supporting an overhead cable | US5087 | 1979-01-22 | US4269123A | 1981-05-26 | Andre Segafredo |
| The safety device detects the derailment of a cable and/or the loss of one or more sheaves of a rocker supporting the cable. It includes a pivotable cross-piece which extends over the side-plates of the rocker and is prolonged laterally to form a component for catching the derailed cable. An appendix can form a temporary support for the cable when a sheave 10, 12 is lost. The pivoting of a crosspiece cuts the safety-line conductor to signal a problem condition.The device can be applied to a gondola lift. | ||||||
| 226 | Overhead cable transport installation with a device for monitoring the components supporting the cable | US897270 | 1978-04-18 | US4220095A | 1980-09-02 | Andre J. Segafredo |
| Transport installation with overhead cable and device for monitoring the cable-supporting components. With each rocker is associated a conductor wire sectioning device for cutting the safety line and extending over the length of the train of sheaves. The sectioning may be brought about by the unlatching of a spring acting on a shear in case of excessive pivoting of the rocker or a derailment of the cable. | ||||||
| 227 | Inflatable protective cushion | US850299 | 1977-11-10 | US4198036A | 1980-04-15 | Larry O'Neal |
| An inflatable protective cushion for positioning around a pole or the like, such as on a ski lift which prevents skiers from striking the pole. | ||||||
| 228 | Brake apparatus with variable brake force for aerial cableways | US522586 | 1974-11-11 | US3980158A | 1976-09-14 | Emil Hirsig |
| A brake apparatus with variable braking force for cable cars having a brake mount or housing connectable with a cable car by a connection shaft and including at least one pressure released catch brake. The catch brake has brake jaws which can be applied with a predetermined brake pressure to a guide track of the cable car, and a brake release for releasing the brake jaws in counter action to the brake pressure. Also provided is a first brake release pressure generator connected with the brake release, an actuable brake applying device connected with the brake release; at least one brake force measuring device coupling the brake mount with the connection shaft for ascending travel of the cable car and at least one other brake force measuring device coupling the brake mount with the connection shaft for descending travel. Finally, a control system controlled by the brake force measuring devices via a brake force balance, with the control system including a second brake release pressure generator controlled by the brake force measuring devices and operatively connected with the brake release in place of the first brake release pressure generator when the applying device is actuated. | ||||||
| 229 | Guide device for the haulage attachments of a ski-lift or similar device | US36573773 | 1973-05-31 | US3865044A | 1975-02-11 | BANCEL GUY HENRI |
| Device for guiding the haulage attachments of an installation for hauling loads by means of a cable over a pulley over which the cable passes, comprising means disposed along the path of the haulage cable, extending from upstream of the pulley, in the normal displacement direction of the cable, to beyond the rotation axis of said pulley, said means comprising wire shaped members which provide at least two support zones with which the attachment is adapted to cooperate in order to be brought eventually with the auxiliary members connected thereto, and whatever the positioning of the assembly, to a position enabling normal passage over the pulley when the cable to which said attachment is connected advances.
