Abstract: Caller-associated information (CAI) may include various data such as names, addresses, telephone numbers, demographic information, messages, other like information and, most preferably, the caller's telephone number. The system includes telephone line-connected telephone answering equipment, decoding equipment and paging equipment. The telephone answering equipment answers or responds to a telephone call originated by a caller. This telephone call includes a datum (such as an identification of the caller's telephone number) and an indication of an intended pager telephone number. The number dialed by the caller to access the system indicates the intended pager telephone number and the appropriate datum transmission can be used to identify the caller's telephone number. The decoding equipment is operatively connected to the answering equipment and it monitors the telephone line to detect and decode (i.e., extract) datum from the datum transmission.

Abstract: An improved outrigger support arrangement for a crane or like piece of equipment is disclosed for stabilization of the crane during work operations. The support arrangement includes an outrigger having a horizontally disposed beam portion and an extensible leg portion fixed thereto extending downwardly and angularly outwardly thereof. Upper and lower beam supports are provided on the wheeled frame of the crane for reactively engaging the outrigger when it is in an extended position. A fluid extensible cylinder and piston is provided for moving the outrigger from the extended position to a stowed position wherein it is substantially completely nested within a cavity defined by the frame of the crane.

Abstract: A hollow rectangular boom formed with four corner sections of identical cross section and plates interconnecting the corner sections is disclosed herein. Each of the corner sections is identical and is generally L-shaped in cross section with first and second legs each having a recess with adjacent pairs of corner sections being interconnected by flat plates received into the respective recesses and welded therein. The invention also resides in the method of assembling the various parts to form the hollow boom sections.
