摘要:
A suspended exercise device comprising an inelastic elongated member that passes through and is supported by a pulley with stoppers on the inelastic elongated member where the placement of the stoppers on the inelastic elongated member determines how much, if any, of the elongated member can pass through the pulley.

There is described a method for monitoring the functionality of an automation system of a plant comprising at least one main processor, parts of the plant being monitored and controlled using a user software, which is constructed of a number of program modules and which is run on the main processor. A co-processor is assigned to the main processor, and a message is transmitted from the main processor to the co-processor. When received, this message is used by the co-processor to start a monitoring time. When a subsequent message is received, this monitoring time is reset before said monitoring time has elapsed, otherwise a fault is identified once the monitoring time has elapsed.

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.

A connector for coupling a preconditioned air source to an aircraft is provided. The connector comprises actuating members rotatably secured to a body. In one embodiment, the actuating members are supported, at least partially, by an integrated bearing assembly. The connector also comprises securing members that are positionably coupled to the actuating members. Accordingly, rotation of the actuating members displaces the securing members. Moreover, the actuating members comprise respective camming surfaces, wherein the camming surfaces define the axial position of the corresponding securing members.

A dispenser includes a body having four side walls, a base and an opening in a top of the body. The base has end walls extending substantially parallel to the side walls so that the dispenser is substantially double walled. A lid is hingedly connected near the top of the body and covers the opening. The lid has a slot therein for sheet material to be dispensed therethrough. The dispenser also includes a platform that supports the sheet material. The platform is movable against forces of a compression element from a first position adjacent the lid to a second position spaced apart from the lid. The end walls have a plurality of ribs extending therefrom. The ribs engage a plurality of corresponding grooves in the platform so that the platform is slidably guided within the body along the ribs.
摘要:
An arrangement and a method for controlling a radiation device, in particular for heavy ion therapy, are described. The arrangement comprises a chain of circuit modules (11-17), each circuit module (11-17) having a separate communication connection to a preceding circuit module and a separate communication connection to a following circuit module. In the method for controlling the radiation device by means of control modules (11-17) arranged in a chain, each control module (11-17) communicates separately with a preceding control module and separately with a following control module.
