Abstract: A bag closure clip including a pair of opposing T-shaped clip members held in pivotal engagement by a U-shaped metal spring. Each clip member includes a jaw, a handle, and a fulcrum. As the handles are squeezed toward each other, the jaws open to allow a bag, such as for snack food or cereal, to be inserted between the jaws. When the handles are released, the spring forces the jaws towards each other to grip the bag and hold it closed. The U-shaped spring is fitted over the fulcrum and is confined to the space between the clip members so that the outwardly facing surfaces of the clip members are substantially uninterrupted.

Abstract: A tote box intended for use in very confined locations such as under the counter of the cashier station in a retail clothing establishment, the box having four flaps, each of which has a tab formed in the center of the edge of the flap. Each wall to which the flap is attached has a gripping aperture into which the tab carried by the flap may be inserted while the box is in use. In addition, a bend line provided between the flap-wall junction and the tab means enables the portion of the flap containing the tab means to be easily inserted into the gripping aperture. Further, a slot in each of two opposing end walls functions to receive and restrain the exterior flap of the two flanking flaps.

Abstract: A wire harness assembly arrangement acquires, prepares and routes various sections of wire by means of a wiring tool apparatus attached to a robotic manipulator. The tool apparatus moves coincident with an arm of the process controlled robotic manipulator and acquires the wire section through a front end portion. The first end of the wire section is fed into the tool apparatus and through a tail end portion of the tool apparatus. The next portion is wound around a spool member disposed within the tool apparatus and rotatable in response to a controlled motor operation. The front end portion is movable in relation to a wire feeding unit so that the wire section wound around the spool member is wound in a helical manner. The wire harness assembly arrangement can also include a strip/crimp station to prepare the acquired wire section for termination. The process controlled robotic manipulator then routes the acquired wire section along a predetermined path to form a part of the wire harness assembly.

Abstract: An escalator having improved brake control, to limit the rate of deceleration immediately following a stop command, and to quickly cause the actual speed of the escalator to closely follow a linearly declining speed ramp of a speed pattern signal. The signal controlling the brake is pulse duration modulated such that the brake responds to the average pulse duration, and braking torque is applied gradually and essentially linearly. The reference speed pattern has a substantially constant portion and a declining ramp portion. To limit the initial deceleration, the constant portion of the speed pattern is controlled to be a function of the actual speed signal, and the declining ramp portion of the reference signal is controlled to start when the actual speed is equal to the constant portion of the reference speed signal.

Abstract: An elevator system including an elevator car having an electromechanical door restraint mechanism which prevents the forceable opening of an elevator car door by passengers when the elevator car stops outside a predetermined zone adjacent to a floor level, at least to an extent which would enable passenger exit from the car.
