摘要:
An expandable arrowhead having a blade-carrying body with a slot that houses at least one movably mounted blade. Each blade can be pivotally mounted about a shaft. In some embodiments, the shaft is fixed with respect to the body. In other embodiments, the shaft is movably mounted with respect to the body, for example by mounting a shaft within the slot so that the shaft moves within the slot with respect to the blade-carrying body. In some embodiments of this invention, a spring element positively holds one or more blades in a closed position or a retracted position, particularly during extreme forces encountered when launching an arrow from an archery bow, such as a compound archery bow. The spring element of this invention can be used to improve blade opening capabilities of conventional blade-opening arrowheads or broadheads.

摘要:
A method for finishing a building board, in particular a wood material or plastic board or a mixture of wood material and plastic. The building board includes a top side and an underside and opposite side edges. The method includes embossing a structure and/or a relief in at least the top side of the building board. A pattern is applied to the embossed side of the building board. The pattern is sealed by the application of an abrasion-resistant layer to the pattern.

The invention concerns a method for controlling a starting aid of a motor vehicle, in particular of a bus. The release of the starting aid takes place as follows: reduction of the braking pressure in accordance with a predetermined first gradient; simultaneous detection of the rotational direction of an output shaft of a transmission of the motor vehicle or of another component which rotates as a function of the rotational speed of the drive wheels; upon detection of a rotational-direction signal which indicates forward travel of the motor vehicle, continuation of the reduction in the braking pressure in accordance with the predetermined first gradient and upon detection of another signal, continuation of the reduction of the braking pressure by way of a second gradient which is reduced in comparison with the first gradient or an increase in the braking pressure.

摘要:
A process for producing a decoration, in particular a wood decoration, and a relief, corresponding to the decoration, on the top side of a woodbased-material board which is pressed in a press, by means of a pressing plate, with a cover layer made of a synthetic resin, in particular a paper layer impregnated with melamine resin, which has been applied to the top side of the woodbased-material board, the relief being stamped, during the pressing operation, by a female die which interacts with the pressing plate, is distinguished in that the decoration and the relief are introduced simultaneously into the cover layer.
