    Abstract: A chair control mechanism having relatively tiltable first and second frame members. A horizontal shaft extends through the frame members for tiltable interconnecting the same. Spring means is connected with the shaft and extends between the frame members for resisting relative tilting movement between the frame members in one direction.

    Abstract: The following specification describes a contour tracing photocell and circuit arrangement for a tracing head utilizing a plurality of equal area photocells in juxtaposed positions transverse to the axis of a line or pattern edge whose contour is being traced. In tracing a line or the edge of a pattern is projected intermediate the center pair of cells. A signal from each cell of the pair is combined with a signal from a respective cell spaced adjacent and on the opposite side of the other cell of the pair to provide a signal representing the direction and displacement of the line or edge. The signals are derived from respective tandemly connected differential amplifiers whose outputs are combined in a resistive summing circuit to derive signals representing direction and displacement of either a line, left pattern edge or right pattern edge for controlling both the steering head and coordinate drive motors to move the head along the line or edge.

    Abstract: The following specification describes a speedometer having a worm gear on the field cup of the magnet driving the speed cup for simultaneously driving an odometer. In addition, the speedometer is provided with a one piece stamped U-shaped bracket for supporting the odometer and cross shaft transmitting movement from the field cup to the odometer with a tubular element fixed to the bracket for rotatably supporting the magnet shaft and cooperating with the bracket to prevent axial separation of the magnet shaft. The odometer dial brackets are positioned to form stops for the speed cup.

    Abstract: A method of fabricating a plurality of buzzers from an initial stamping. The stamping is formed having a configuration defining the metal parts of four buzzers with individual circuit portions interconnected by webs. Respective plastic bases are molded to the circuit portions of each buzzer at respective positions on the stamping and the webs are then sheared to both separate the buzzers and enable the appropriate electrical circuits to be completed.

    Abstract: An electromagnetic vehicle turn signal flasher in which lamps are lighted and a bulb outage relay is energized through normally closed contacts on operation of the turn signal switch. The relay armature operates to energize a timing relay, which deenergizes itself and momentarily opens the normally closed contacts to deenergize the outage relay and extinguish the lamps. The contacts, on reclosing, relight the lamps and energize the outage relay to repeat the cycle. The outage relay armature either does not operate or releases before the closed contacts have opened, if a lamp has failed, to maintain the dashboard indicator lamp continuously lighted for signalling the lamp failure. To enable the operated outage relay armature to release on lamp failure, the armature is held a predetermined distance from the core so that as the resistance of the remaining energized lamp filaments increases, the outage relay current decreases sufficiently to cause armature release.
