Abstract: A transporter vehicle comprises two lifting devices which carry respective jacks and which can be joined at their ends by cross bars to form a rectangular dolly with a central opening therein. The lifting devices each have front and rear wheels so that the dolly can be rolled on floor surfaces. In practice, the two are placed on opposite sides of a load seated on a floor in the opening between those devices, the jacks are placed under the load, the cross bars are assembled with the side frames, the load is jacked up on its opposite sides to be above the floor and the load may then be transported. The jacks may include linkages which cause the load to be lifted wholly vertically while not undergoing any horizontal translational movement.

Abstract: A central interconnector unit provides for the possible transfer therethrough of RF signals passing in m signal paths from respective signal sources to respective antennas disposed at a cellular telephony cell site to radiate those signals into different angular sectors of the site. The unit has a total capacity for amplifying such signals which is provided by n similar circuit pack amplifying sections (n being greater than m), having respective inputs and outputs connected to corresponding jack terminals on a backplane in the unit.

Abstract: The invention is for improvements in a payout tube for a container-packaged coiled cable in which the tube in use is in the container along with the coil, a stub of the tube at its exit end protrudes through a hole in a container wall, and the tube is secured to that wall by having portions of the wall around the hole interposed between (a) a flange or flanges disposed on the tube on one side of such wall in contact with such portions, and (b) locking elements axially spaced on the tube from such flange or flanges and disposed on the other side of such wall in contact with such portions. Here, such locking elements are struts coupled to the body of the tube to be movable between radially inner positions at which they will pass through such hole and radially outer positions at which they cooperate with the flange means to secure the tube to such wall as described above.

Abstract: The opening and closure of the contacts of a push-button actuated switch duces across impedance means a voltage which is stably high and low when such contacts are maintained closed and open, respectively. Bouncing of the contacts after their initial closures and openings produces superposition on the stable levels of such voltage of trains of impulses caused by such bouncing. A bistable semiconductor flip-flop is coupled to the impedance means to sense such voltage and to assume a "high" state and a "low" state only when the stable level of such voltage is, respectively, high and low and, further, the flip-flop receives a clock signal. A retriggerable semiconductor monostable multivibrator is coupled to such impedance means to be triggered by such impulses from its stable "off" state to its unstable "on" state which is repetitively renewed by repetitive retriggering of the multivibrator.
