Abstract: At their lower edge (6) excavators are provided with a tooth arrangement consisting of two parts (1 and 2), one part (2) being attached to the bucket (6) and the other part (1) being exchangeable. The two parts (1 and 2) are held together by means of a male and female relationship and a transverse aperture (3 and 25) with a locking body (4). When the exchangeable part (1) becomes worn it may start to become unstable. The object of the present invention is to eliminate this drawback and this is achieved in that the locking body (4) comprises two opposing flat surfaces, provided with one or more spacers (15-20) intended to restrict approach of the two surfaces towards each other.

Abstract: This invention relates to a filter in which a fuel pump for drawing fuel from a tank and a fuel filter unit for filtering foreign matter from the fuel which has been drawn from the tank by the fuel pump are integrally assembled together. More particularly, the invention relates to a filter improved such that the amount of electric charge, which builds up on the filter, is not increased to such an extent that the resin is rapidly deteriorated. In one embodiment, when forming a filter by assembling a generally cylindrical filter element around an outer periphery of a generally cylindrical pump, a cover for covering the filter element is made of a nonconductive material, and the generally cylindrical filter element is of the type which filters foreign matter from the fuel by causing the fuel to flow radially therethrough. With this type of filter element, the amount of electric charge can be reduced.

Abstract: Method and apparatus for determining the concentration of an analyte gas using a gas measurement device comprising a gas sensing element having an electrical current output dependent upon concentration of a gas being measured, means for measuring the electrical output signal and means for limiting diffusion of the gas being measured to the gas measurement device and defining a path for gas being measured to enter the gas measurement device. Concentration is determined by exposing the gas sensing element to the analyte gas at a first rate of diffusion and diffusivity, and measuring the output signal for a time sufficient to establish a first steady state signal, reducing diffusion of gas to the gas sensing element to a second rate of diffusion and diffusivity, and measuring the output signal for a time sufficient to establish a second steady state signal, and calculating the concentration of the analyte gas based on the second diffusivity and the first and second steady state output signals.

Abstract: The invention concerns a wheel for a flexible track comprising two rolling paths (36) surrounding an intermediate zone (50), in particular a drive zone. At least one of the rolling paths has a multiplicity of cavities (200) of selected form opening radially towards the outside of the wheel and laterally towards the edge of the wheel so as to promote lateral evacuation of any material object liable to be caught between the wheel and the flexible track. The wheel is generally used for all-terrain vehicles.

Abstract: Resistance welding machines may include one or more temperature sensors that measure the temperatures of one or more heat generating elements within the welding machine, such as the welding transformer, the welding cable, the welding gun and/or the welding current switching element. These heat generating elements generate heat due to the passage of the welding current and can be damaged if not properly cooled. A processor is provided to receive temperature signals from the temperature sensors(s) and actuate a warning output circuit when the temperature of one or more of the heat generating elements rises to a high temperature warning temperature. This high temperature warning temperature is preferably lower than an upper limit temperature at or above which the heat generating element may be damaged due to overheating.
