Abstract: The disclosed commercial coin-operated scale-platform massager has a frame, a foot platform, and means including a weight cell for supporting the foot platform relative to the frame. The weight cell provides the primary support for the foot platform, and is distorted by the weight of a person standing on the foot platform and calibrated to determine the weight of the person. A driving vibrator in the form of an electric motor having an eccentric weight keyed to its output shaft is mounted relative to the foot platform, operable when the driving vibrator is activated to vibrate the foot platform relative to the frame. Snubber means allow limited movement of the foot platform relative to the frame. A printer may provide a readout for a permanent record of any information including the weight of the user.

Abstract: The disclosed commerical coin-operated scale-platform massager has a frame, and a foot platform supported by a weight cell movably relative to the frame. The weight cell provides the primary support for the foot platform, and is distorted by the weight of a person standing on the foot platform and calibrated to determine the weight of the person. A driving vibrator in the form of an electric motor having an eccentric weight keyed to its output shaft is mounted on snubber means relative to the frame, and linking means connect the driving vibrator and foot platform together, operable when the driving vibrator is activated to vibrate the foot platform relative to the frame, as a platform massager.

Abstract: A coin-operated TV system is disclosed that uses separate TV displays or sets, each having an individual coin acceptor, program selector and control. Centralized sources of pre-recorded and/or publicly broadcast programs are provided via TV modulators as separate channels hard wired to every TV set. A computer is also hard wired to every TV control. The computer and TV control provide that each TV set normally receives and exhibits one channel continuously, at no costs. If the program selector at any TV set is switched to another specific channel and the coin acceptor has received a suitable deposit, the computer and TV control shift that particulat TV set to the selected channel. The selected channel will operate for a predetermined duration or until the selected program has ended. Thereafter, the TV set will be shifted back to the free channel, unless a different specific channel had earlier been selected and paid for.

Abstract: There is disclosed a test element advancing mechanism for use in an analyzer to move such test element from station to station, and a method of doing the same. The mechanism features a support surface over which the test elements move in a predetermined direction, a test element mover for engaging and moving the test elements, means for reciprocating the mover along a surface disposed to one side of the support surface, a portion of said mover being constructed to engage the reciprocating means, and means for pivoting the mover about an axis that extends parallel to the movement direction so that the engaging means are moved into or out of contact with such test elements. The test element mover includes a lever arm emanating from one side of the reciprocating means engaging portion, constructed to interact with the pivoting means.

Abstract: Improved optical means for automatically controlling or monitoring the position of a relatively moving member such as a tool tip in a numerically controlled machine tool has an image of a region of a datum line projected on to a slit in an optical system. Light passing through the slit falls on to a photoelectric detector device which comprises an array of discrete elements. The elements are electronically scanned sequentially and an electric circuit is provided to produce an output signal when a preset change in incident light intensity is detected by any of the photoelectric elements thus indicating the presence of the movable member at the datum line. There may be two slits projecting images of the region around two transverse datum lines on to two separate arrays so that the movable member can be controlled in two dimensions. Alternatively, in place of two separate arrays and two slits a single two dimensional array may be provided suitably masked.
