Abstract:
A lifting device having front plates at the end of the winch drum the front plates being provided with flanges to which bracket elements are secured. The bracket elements are interconnected by means of tension rods as well as carriers for the wheels to obtain a rectangular configuration.
Abstract:
This invention makes available a photopolymerizable material containing at least one polymeric binder, photopolymerizable monomer and, at least one photoinitiator, and having a special shear modulus and a specific thickness. These photopolymerizable materials are used in processes for preparing images, especially multiple color proofs. Temporary supports and pigmented transfer materials specifically designed for the preparation of multiple color proofs are described. A pigmented element having a pigmented transfer layer with a polymeric component of polycaprolactone, polytetrahydrofuran and mixtures thereof is disclosed.
Abstract:
A shift control arrangement is provided for rail vehicles to bring about the simultaneous shifting of all directional guide wheels on the vehicle at the same time, including those in both the front and rear undercarriages of the vehicle. This is achieved by interconnecting the shift linkages of each undercarriage and, preferably, by placing the connection in the longitudinal axis of the vehicle.
Abstract:
A railway maintenance car is provided for elevated railways which uses the rails, or rail of a monorail system, to move to the place of maintenance, thus avoiding obstruction of ground areas beneath the railway. The car of the invention includes telescoping cantilevered maintenance access platforms movable laterally and longitudinally of the car to place maintenance personnel alongside stalled cars on the rail or rails, and to move such personnel under the rail itself for maintenance and repair. The telescoping features of the invention include independently operable devices at each end of a telescoping platform in order to extend such platforms at an angle to the axis of the car for accommodating curved rail access.
