Abstract: Disclosed is a method and transporter for lifting, moving and installing heavy and bulky loads such as machinery, equipment and appliances. The transporter comprises a frame for straddling the load; Once a first end of the load is attached to the transporter; a suspension member or similar device is affixed to the load and tightened relative to a handle of the frame to suspend the opposite end from the frame using the suspension member. The handle of the frame may then be used to lift the load, balance it on the wheels and permit a single user to safely and comfortably transport the load. Also disclosed is transporter having jacks for lifting a load onto a chassis having three or more wheels, at least one of which is steerable.

Abstract: A line interface unit for a digital local office for telephonic communication has a circuit connected to telemeter low-frequency signals around a line, alternating current, hybrid coupler and reinsert the same signals in the call path at the input to an analog-to-digital encoder that is coupled to a time division switching network. Each interface unit also includes circuits for multiplexing various line unit, digital, status signals with coded call signals and for demultiplexing line unit, digital, control signals from coded call signals. That network is utilized by an office common control for interconnecting various call paths with one another and for interconnecting the common control with the line interface units as required. The common control includes a time-shared digital filter for processing the telemetered signals for various office purposes.
