Abstract: The cross coil type meter has a magnet rotor and a stopper plate inside a coil bobbin. The magnet rotor is driven by a combined magnetic field produced by a cross coil wound on the coil bobbin. A pointer on a dial plate is attached to the magnet rotor's shaft so that it can indicate the magnitude of a measured quantity. The stopper plate engages with the magnet rotor to stop the pointer at a zero position on the dial plate. But when due to some assembly errors the stop position of the pointer and the zero position on the dial plate do not agree, the position of engagement between the magnet rotor and the stopper plate can be adjusted by manipulating the stopper plate from outside until the two positions agree.

Abstract: A bimetallic indicator includes a bimetal being deformed by heat generated by an electric current supplied to a heat coil wound around the bimetal, a pointer moved in relation to the deformation of the bimetal and indicating a measured value in accordance with an amount of electric current supplied to the heating coil, and a driving gear, which is rotated by the deformation of said bimetal. The driving gear includes two first pitch portions each having a plurality of teeth with a regular pitch and a second pitch portion provided between the first pitch portions and having a pitch smaller than that of the first pitch portion. A driven gear to which the pointer is mounted is engaged with the driving gear and rotated together with the pointer by the rotation of the driving gear. The rotation of the driving gear is transmitted to the driven gear only when the first pitch portion of the driving gear is in engagement with the driven gear.

Abstract: In an electromotive control device having an end disconnect switch, two circular conductive paths are arranged on an insulating support, at least one of said paths being less than an entire circle. Wiper contacts which connect the conductive paths are electrically connected to each other and are connected to a wheel which is driven by a motor, the wheel being mounted coaxially to the conductive paths. The limit disconnect switch and thus a setting element can be manufactured at low cost by the invention.

Abstract: An odometer for use by a golfer in the measurement of distance covered by each shot. The odometer attaches to the wheel of the cart and counts revolutions or parts of a revolution of the wheel through the use of a magnetic head that rotates past a Hall effect sensor. A digital readout indicator displays yards covered.

Abstract: An electrical impulse operated number wheel counter with coaxial number wheels (2); transfer pinions (8); a reciprocable pawl (12) engaging the first number wheel and a solenoid (20) driving the pawl, has a series of leaf springs (33) carried on the solenoid armature (24). In the rest position the leaf springs (33) engage bosses (9) on the transfer pinions to ensure that the number wheels (2) are correctly aligned but when the solenoid (20) is energized to effect a count, the movement of the armature (24) lifts the leaf springs away from the transfer pinions (8) which therefore rotate unhindered. An additional effect of the leaf springs is to reduce the power consumption of the counter and this effect can still be achieved with other spring arrangements. A shock resistance element (50) is freely rotatably mounted in the path of the pawl (12) so as to be struck in the event of shock induced movement of the pawl, substantially to eliminate spurious shock induced counts.

Abstract: A meter includes a single sweep hand dial for indicating maximum demand in a predetermined time period as well as a multidial decade register for recording cumulative demand. The sweep hand dial is driven by a pusher gear. A pusher arm urges the pusher gear in a first rotational direction to record maximum demand during the period. To reset the mechanism, a button is pushed manually to axially displace a reset gear into meshing engagement with a relatively high speed gear train driven by the timer motor. As the reset gear is thus moved, pins on the reset gear are displaced from stowage slots in a plate, and as the reset gear rotates, the pins ride on the plate until the reset gear completes a full cycle of operation during which time another pin on the reset gear engages a second tab on the pusher gear to reset the pusher gear in a rotational direction counter to that in which the pusher arm had rotated the pusher gear.

Abstract: Gasoline dispensing apparatus with cost and volume registers composed of banks of rotary electromagnetic indicators, each having an electromagnetic stator with a drive coil for indexing a respective rotary indicator wheel and a sensing coil for sensing wheel rotation and direction, and an indicator operating circuit for accumulating, and for indexing the indicator wheels for registering, the cost and volume of fuel delivered. The sensing coil is employed for monitoring and verifying wheel rotation and each indicator wheel is indexed by energizing the respective drive coil in the appropriate direction and for an optimum interval controlled by the respective sensing coil.

Abstract: A device adapted for special use in a reset timer/counter unit to return various digital counting subwheels to their reset condition after a timing or counting cycle. The device includes a first ring formed from a permanently magnetizable material having a generally circular first pole surface with a set of opposite polarity magnetic poles arranged in a selected pole pattern on the first pole surface and means for securing the first ring onto one of the subwheels or other device to be returned to a selected position. The second ring formed from a permanently magnetizable material is provided with a generally circular second pole surface generally facing the first pole surface and having opposite polarity magnetic poles arranged in a pole pattern matching the selected pattern of the first surface with poles of the first surface generally facing opposite polarity poles of the second surface when the members to be controlled are in a selected angular returned, or known, position.

Abstract: A setting mechanism incorporated in a digital display device which includes a movable first digit carrier; a motor driving the first digit carrier in a normal digit-advancing operation; and a movable second digit carrier. The setting mechanism has a drive member continuously driven by the motor, a clutch connected between the drive member and the second digit carrier. The clutch, when in its engaged state, couples the drive member to the second digit carrier for imparting a setting motion to the latter; and a manually operable actuator connected to the clutch for operating the same.
