United Technologies Corp. (Hartford, CT)

International Classification

B64C 2704, F16F 710

U.S. Classification

244 1727

Abstract

A vibration isolation system in which a supported body is supported from a vibration excitation body which is prone to vibrate at a predominant frequency and to impart such vibratory forces and motions to the supported body. The isolation system is of the antiresonant type and operable to provide vibration force and motion isolation of the supported body from the vibration excitation body both axially along and rotationally about three mutually perpendicular axes, thereby giving the supported body six degrees of vibration isolation from the vibration excitation body.

Assignee

Ford Motor Company (Dearborn, MI)

International Classification

B61B 1000

U.S. Classification

1041724

Abstract

A power and free conveyor system is provided which utilizes a difference in height between the wipe in power trolley and the wipe out power trolley, with or without a camming down of a retractable wide dog of the free trolley, to allow the wipe in power chain to wipe in over the retractable dog without any possibility of lateral interference. Thereafter the elevation of the wipe in power trolley and the wipe out power trolley are the same. Improved stop means operating to push down the retractable dog and therefore cause disengagement of the retractable dog from the power chain dog are also provided.

Abstract

A mailbox is provided with a lockable letter-mail compartment within in the form of a rectangular box having at least four sides and a hinged door with a key operated mechanism for locking it in the closed position, secured to the floor, side or roof of a mailbox for use in motorized delivery routes, or in the form of a shelf secured between side walls of the mailbox and a hinged door with a lock. The compartment has a slot for receiving letter mail without opening the door of the compartment. The slot is preferably in the locked door of the compartment. The height of the lockable compartment is sufficient to permit mail to be extracted through the hinged door, but of a height significantly less than the height of the mailbox to permit mail other than letters to be placed in the mailbox outside of the compartment.
