Abstract: An automatic telephone dialer is disclosed for operation with both a rotary type and push button conventional telephone. The automatic dialer enables regular conventional dialing procedures to be employed with the automatic dialer in place without interfering with normal telephone operation, and further, can be installed without interfering with, touching or in any way altering the telephone company's lines or equipment. Any desired number can be arranged to be automatically dialed and an indexing device is utilized so that when a specifically sought number is to be dialed, the index pointer is moved to that location, and the telephone number is automatically dialed.

Abstract: A motor-driven vehicle movable by a chain belt or similar device, the chain belt carrying a series of electromagnetic pads. The pads, when energized, cause a strong electromagnetic force to be generated enabling the motor-driven vehicle to adhere to an inclined steel surface, such as of a ship. The vehicle may be used for carrying various equipment between points on the inclined surface or on the ship and can be used for staging purposes. The electromagnetic pads or shoes provide a firm and strong gripping means enabling the vehicle to safely move about the ship's surface.
