Abstract: The invention relates to an assembly system used to form insulating floors, in which two types of elements are coupled to one another, namely: hollow prismatic floor modules (100) including one face (110) which forms the load-supporting useful surface and containing cylindrical elements (160, 162, 164, 166) for receiving coupling elements (200); and coupling elements (200) comprising cross-shaped elements with U-sections forming the arms thereof, intended to receive the vertical faces (140, 142, 144, 146) of the floor modules (100), and posts (230) which are coupled to the corresponding hollow cylindrical elements (160,162,164,166) of the floor modules (100) to be joined. The geometric configuration of the modules (100) and the coupling elements (200) ensure that the load on the assembled floor is transmitted to the ground through the vertical walls (140,142,144,146) of the prismatic body (100), the coupling elements (200) and a central cylindrical load body (170).

Abstract: A flame ignition device for a gas burner is described, comprising at least one ignition circuit and electric switching means that are associated with the gas tap for the respective burner. The electric switching means include at least one electric contact member (50) which is integral, at least in translation, with the control rod of said gas tap.

Abstract: A data storage arrangement includes a storage device including a program storage for storing a predetermined operation program, a controller for controlling operation of the storage device based on the operation program, and a memory, and a power source adapted to drive the controller according to the operation program to transfer data stored in the memory to another memory in another storage device connectable to and disconnectable from the storage device.

Abstract: To improve tracking, an exercise treadmill is provided with a frame including molded plastic pulleys, having an integral gear belt sprocket, an endless belt extending around the pulleys and a motor operatively connected to the rear pulley to drive the belt. The pulleys are molded out of plastic and have a diameter of approximately nine inches. A mold and method for producing large diameter treadmill pulleys having an integrally molded sprocket are also disclosed. A deck underneath the running surface of the belt is supported by resilient members. A positive lateral belt tracking mechanism is used to correct the lateral position of the belt. A belt position sensor mechanism is used in combination with a front pulley pivoting mechanism to maintain the belt in the desired lateral position on the pulleys. The exercise treadmill also includes a lift mechanism with an internally threaded sleeve engaged to vertically aligned nonrotating screws. A user display of foot impact force on the belt is also provided.
