A concrete lid for an in-ground utilities box includes a plastic reinforcement structure filled with concrete. The plastic reinforcement structure includes one or more plastic sidewalls that protect the edges of the lid from damage. The upper and lower surfaces of the lid are exposed concrete (with the exception of the upper and lower edges of the one or more plastic sidewalls). The one or more plastic sidewalls laterally surround a plastic reinforcement grid, which is centrally located between the upper and lower edges of the one or more plastic sidewalls. The one or more plastic sidewalls can be integrally formed with the plastic reinforcement grid. The plastic reinforcement grid reinforces the concrete lid, eliminating the need for separate reinforcement material. Support struts can be used to support the plastic reinforcement grid while wet concrete is being poured into the plastic reinforcing structure.

An aircraft electrical connector is provided with features to allow facile engagement with an aircraft and strong retention forces. The aircraft electrical system may include the aircraft electrical connector having a unique biasing mechanism and modular construction, wherein the biasing mechanism is configured to place differential forces onto mating electrical connectors from an aircraft. The biasing mechanism may be operatively coupled to a handle or trigger, which may be easily engageable by an operator. In one embodiment, an electrical connector may include a cam plate disposed between electrical connectors. The cam plate is configured to place differential forces on mating connectors inserted into the electrical connectors. In another embodiment, an electrical connector includes a moveable shaft that is disposed between electrical connectors. The shaft is configured to bias the position of the electrical connectors to place differential engagement and retention forces on mating connectors inserted into the electrical connectors.

In certain embodiments, a PCA connector has a nylon body, wherein the nylon is durable, corrosion resistant, and exhibits excellent strength over a large range of temperature and moisture conditions. The nylon body may be described as a single structure with integral features, such as a bearing portion, a latch housing portion, a latch guide portion, and so forth. Thus, the number of parts is significantly reduced by the one-piece design of the body. In addition, the PCA connector may include a latching mechanism configured to secure the PCA connector to an aircraft. For example, the latching mechanism may include a pair of levers, which engage a pair of latches on opposite sides of the nylon body. In some embodiments, the levers may be rotated in opposite directions relative to one another to impart movement of the latches in the same direction, e.g., an axial direction. Also, some embodiments of the latching mechanism include a cam between the levers and the latches, respectively.

The invention relates to a method and an automated system for determining the processing sequence of function blocks of a technological function. According to said method, a first function block, whose outputs are respectively disconnected or form exclusively one or more output signals of the technological function, is determined. Starting from said first function block, a second function block is sought in the opposite direction to the signal flow direction, whereby the block inputs of said second block are respectively disconnected or receive one or more input signals of the technological function only. An identifier is given to all block inputs, which are disconnected, receive an input signal from the technological function only or are connected to at least one block output of another function block whose block inputs have previously been given identifiers, starting from and including the second function block, running through subsequent function blocks in the signal flow direction up to and including the first function block. The function block is marked as soon as its block inputs have been given identifiers. Finally, the processing sequence of the function blocks is achieved in accordance with the marking sequence of the function blocks.

The invention relates to a redundant automation system, and a method for operating one such automation system. The inventive automation system comprises two automation appliances with which a common memory unit is associated, on which status data of the automation appliances can be stored. In this way, the automation appliances have direct access to a common database and a memory compensation is dispensed with in the event of an error during the switchover to the standby automation appliance.

An inoculation storage assembly and method of preserving sterility including an inoculation device (20), a storage rack or container (84, 184), and a handling tool (60, 160). The inoculation device (20) being an elongated ember (22) with a gripping section (24), an inoculation section (26), and a seal (25) carried by elongated member (22). The seal (25) preferably having an arcuate surface (19) for sealing engagement against a seal contact surface (162, 262) in a cavity (86, 186) in the storage rack (84, 184). The storage container (84, 184) including an open upper end or opening (88) and a seal contact surface (162, 262) dimensioned to sealingly receive the seal (25), with the inoculation device (20) being mounted in sealed relation to the cavity (86). A handling tool (60, 160) capable of releasable coupling to gripping section (24) of the inoculation device (20) is provided. A method of using the inoculation storage assembly and preserving sterility is also disclosed.
