Abstract: A cantilever-weighted golf putter which is characterized by an elongated putter head having a rounded bottom and sides and a flat top, with a longitudinal heel bore and toe bore provided in the heel and toe, respectively, of the putter head. A pair of threaded plugs fitted with a central opening and a recessed area communicating with the central opening are threaded into the heel bore and toe bore, respectively, for receiving bolts, such that the bolt heads are recessed in the recessed areas of the plugs and the threaded bolt shanks extend into the heel bore and toe bore, respectively. Each of the bolts is fitted with internally-threaded weights threadably secured in place on the bolts by means of nuts, such that the multiple weight system on each bolt is mounted in cantilever relationship in the heel bore and toe bore, respectively, of the putter head, without touching the heel and toe bore walls.

Abstract: A video communication network (20) capable of providing a plurality of simultaneous textual data video frames to a plurality of keystations (22, 24) from a plurality of computer systems comprising at least two different data bases having incompatible keyboard protocols or character codes (40, 47, 46a, 46b) employs a single keyboard (28, 38) at the keystation (22, 24) to both selectively communicate with various different data base computer systems (40, 47, 46a, 46b) and enable keyboard generated dynamic selection of a textual data video display from a multiplexed plurality of simultaneously provided composite video signals corresponding to the plurality of video frames. Each keyboard (28, 38) may control anywhere from one VDU (26) up to four such VDUs (30, 32, 34, 36), by way of example.
