Granted: 1992-04-21
Abstract: ABSTRACT OF THE DISCLOSURE          The lift unit comprises a bracket portion that is secured to the trailer tongue and a hinge portion that pivots on the bracket portion about a horizontal axis to raise and lower a chain for flexing and relaxing a spring bar that when flexed, serves to transfer a portion of the tongue weight to the towing vehicle.  A flat rectangular member is eccentrically mounted on the side of the hinge portion to hang in the 6:00 o'clock position unless acted upon by influences other than gravity.          When the hinge portion is operated to raise the chain and thereby flex the spring bar, a longer side of the rectangular member abuts and rides along the edge of a side of the bracket portion resulting in the member being swung clockwise to about the 8:00 o'clock position when full chain elevating position is reached.    At this time one corner of the member drops into a notch in the bracket portion and prevents the hinge portion from being operated in the direction of chain lowering.  The member is kept in this position by passing a tethered pin through the member and the hinge.  When the pin is removed, the member can be swung further clockwise to about 4:00 o'clock to enable the chain to be lowered.  The edge of the bracket's side acts on the member during chain lowering to swing the member counterclockwise back to 6:00 o'clock thereby automatically resetting the member for automatic locking when the chain is again raised.

Abstract: "Telephone Registration and Cancellation Control in a Wide Area Cordless Telephone System"                  ABSTRACT OF THE DISCLOSURE In a wide area cordless telephone system, a wide service area is divided into a plurality of local service areas identified respectively by unique codes. Each local area has home position portable cordless telephones to which telephone numbers are permanently assigned and can accommodate roaming non-home position telephones belonging to other local areas. Each telephone receives a pre-registration polling signal from one of access units located at key points and returns a pre-registration response signal if a unique code contained in the received polling signal mismatches a stored area code. A controller in each local area assigns a reserved telephone number, if available, to a roaming telephone in response to such a response signal and registers this cordless telephone in memory. The controller then transmits an acknowledgement signal indicating the completion of a registration. The registered telephone responds to it by returning a post-registration signal which is monitored by the controller. The registration of this telephone is cancelled if the controller fails to receive the post-registration signal for a prescribed time interval.
