A split door assembly for a grinding mill includes an upper door assembly with an upper door exterior surface. The upper door exterior surface supports a journal actuator assembly and the upper door assembly is pivotal with a journal that has a grinding roller mounted thereon. The split door assembly includes a lower door positioned below the upper door assembly. A hinge assembly pivotally connects the upper door assembly and the lower door. The upper door assembly and the lower door are pivotable together between a closed position and an open position. When in the closed position, the upper door assembly abuts the lower door. When in the open position, the upper door assembly is pivoted away from the grinding mill, the lower door is pivoted away from the grinding mill and the lower door is pivoted relative to the upper door assembly.

An apparatus for controlling bus doors (14, 16) that are arranged as a pair of doors that move in coordinated relation between door open positions and door closed positions, enables passengers to access an interior area (12) of a bus (10). The apparatus includes an actuator (28, 226). The actuator includes a drive lever (34, 228) that is selectively rotationally movable between rotational positions in which both of the doors are in the open positions and in the closed positions. Exemplary arrangements include at least one controller (128) that is operative to prevent the doors from causing damage to or from being damaged by engagement with obstructions. The controller further enables a bus driver or other authorized user to control access to the interior area of the bus using a user mobile device (144).

A control system for a shutter is disclosed. The shutter includes a force-bearing mechanism and a plurality of slats. The control system includes a power source, a driving device connected to the power source to output a first driving force, which drives the force-bearing mechanism to rotate the slats, and a clutch mechanism, which includes an input member and an output member which are drivable to be connected together for synchronous operation, or to be mutually disconnected for independent operation. When the driving device outputs the first driving force, the input member is engaged with the output member, and the first driving force can be transmitted to the force-bearing mechanism through the clutch mechanism to rotate the slats. When the driving device stops, the input member is disengaged from the output member, and the slats and the force-bearing mechanism are rotatable relative to the driving device.

The present application provides a safety gate apparatus which is configured to receive the delivery of goods by way of fork lift therethrough while simultaneously preventing falls and injury. A version of the safety gate apparatus comprises a first and second support structures which are laterally disposed defining a delivery space therebetween for ingress and egress of the forks of the fork lift, and a moveable gate assembly supported by the first and second support structures moveable between a closed, default position and an open position.

A system for transferring torque with zero lash from a driver to a driven object is provided. The system includes a shaft disposed about a rotational axis and a hub defining a bore that receives the shaft. The shaft and hub are each configured for coupling to one of the driver and driven object. The shaft defines a flat on a radially outer surface and the hub defines a flat on a radially inner surface opposing the flat in the shaft. In one embodiment, the shaft includes a threaded bore and the hub includes an aligned through bore. Rotation of a threaded fastener in the bores draws the flat into engagement. In another embodiment, the hub includes a threaded through bore. Rotation of a fastener extending through the bore and engaging the shaft diametrically opposite the flats urges the flats into engagement.

The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four-sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

The link assembly constitutes a mechanical connection between a cabinet door (108) and a toe kick plate (112) of the cabinet with both panels being hingedly attached to the same cabinet sidewall (114). The link assembly causes the toe kick plate (112) to move in synchronization with the movement of the door (108) and, when the cabinet door (108) is opened, the link causes the toe kick plate (112) to move into a position underneath the door (108). The link assembly pivots and self-adjusts dimensionally as required throughout the range of movement of the two hinged panels. The link assembly incorporates a resiliently biased over-center mechanism which urges the door (108) to remain in the open position until closed intentionally. The link assembly provides dual-axes adjustability for, and also supports the weight of, the toe kick plate free-swinging edge (112a).

An automatic built-in closing apparatus includes at least one common pivoting shaft that is driven by a unique motor, intermediate gear wheels and a clutch coupled to control doors of a series of lockable compartments pertaining to a same block of an electronic locker unit and a set of freewheels and overload clutch which is mounted on the common pivoting shaft as a hinge for each door of the series of lockable compartments.

An access control system controls synchronous or coordinated motion of two or more gates using a controller that calculates travel time for each gate and that adjusts the speed of the motors driving the gates to so allow the gates to reach the open and/or closed position at the same time, regardless of the length of the individual travel paths of the gate.

A console box includes a box body that includes an opening portion, a lid supported by a hinge shaft on the box body, and an opening/closing mechanism that tilts the lid. The opening/closing mechanism includes a main rack that includes an engaging portion and a sub-rack that includes an engaged portion. When the lid is tilted between an opened position and a closed position, the engaged portion engages the engaging portion and restricts sliding of the sub-rack on the main rack. When the lid is further tilted from the closed position in a closing direction in which the lid closes the opening portion and when the lid is further tilted from the opened position in an opening direction in which the lid opens the opening portion, the engaged portion is disengaged from the engaging portion to cancel the restriction imposed on the sub-rack by the main rack.
