With Dry Run Work Driving Means Patents (Class 269/12)
  • Patent number: 9540181
    Abstract: A pallet for conveying pieces or components in assembly lines. The pallet includes a base structure, a rotatable platform above the base structure, a pair of vertical uprights, a pair of vertical columns respectively supported within said vertical uprights and an arch-shaped cross-member selectively engageable with the vertical columns. The arch cross-member selectively connected to an assembly component whereby the component may selectively be positioned at different heights and angular orientations to the platform and base for ease of access to the component by a user.

  • Patent number: 9280918
    Abstract: The invention relates to a machine that simulates movement during transport, for the testing of packaging elements. The machine comprises: a load platform (1), the lower part of said platform having attached thereto a plurality of upper ball joints (3, 61,71) with a ±30° rotation angle, coplanar with the axis of rotation of a rotating support (5, 5?, 5?); and a lower platform (6) which is located opposite the load platform (1) and which is provided with anchors for attaching same to a vertical vibration table (25,26). Additionally, a central support (7) is located between the load platform (1) and the lower platform (6). Furthermore, a plurality of mutually independent hydraulic servo-actuators (8,8?,8?) are attached between the upper spherical ball joints (3) and the lower ball joints (4), said servo-actuators (8,8?,8?) being placed along two perpendicular planes that pass through the center of the rotating support (5, 5?, 5?), forming a 90° angle.

  • Publication number: 20140312547
    Abstract: A handling attachment includes four vacuum cups to suction-hold a suction target surface of a workpiece and a support member which holds the vacuum cups so as to maintain a position relation among the vacuum cups. A device for positioning the vacuum cups has a base plate and four positioning jigs disposed on the base plate. The positioning jigs have, at their upper end, a dummy workpiece surface to be abutted with the vacuum cups. The dummy workpiece surface is allowed to change the position and to tilt in any direction.

  • Patent number: 7554253
    Abstract: A spark plug for an internal combustion engine is provided which includes a metal shell, a porcelain insulator, a center electrode, a main ground electrode, and auxiliary ground electrodes. Each of the auxiliary ground electrodes has an end face facing the insulator to define an auxiliary spark gap. The end face includes an increasing-radial distance surface which is located at a distance from a longitudinal center line of the spark plug in a radial direction thereof which increases as approaching to the metal shell. The insulator nose has a wall thickness T meeting a relation of 0.3 mm?T?0.7 mm. This avoids a great local increase in electrical field strength on the auxiliary ground electrode to minimize excessive discharge within the auxiliary spark gap to enhance carbon fouling resistance and durability of the spark plug.
