20160138986 | A METHOD OF MEASURING ELONGATION OF A FASTENER WITH ULTRASOUND, PERFORMED BY A POWER TOOL, AND A POWER TOOL - The invention relates to a method of measuring elongation of a fastener by means of minimum peak side lobe (MPS) coded ultrasonic signals, and a power tool configured to performing the method. MPS coded signals with different base frequencies are transmitted into the fastener and a corresponding set of reflected signals are received from the fastener. Each reflected signal is cross-correlated with the corresponding transmitted signal, and a quality attribute of each transmitted signal is determined from the cross-correlated signals. Based on the quality attributes at least one parameter of an ultrasonic measurement signal is determined and the measurement is performed by transmitting the ultrasonic measurement signal into the fastener, and receiving a reflected ultrasonic measurement signal. | 05-19-2016 |

20090272762 | Two stage grease gun - A two stage grease gun with a handle capable of being actuated by a user is provided. The gun includes a high volume/low pressure piston for delivery of grease at a high volume and low pressure. A high pressure/low volume piston for delivery of grease at a high pressure and low volume is also included. Acutation of the handle by the user causes both pistons to move. A by-pass check valve is present and is configured to actuate based upon a backpressure. The by-pass check valve is not actuated by the user and effects the amount of grease dispensed by way of the high volume/low pressure piston. An associated method is also provided. | 11-05-2009 |

20080271572 | Method for Recovering Rare Metals in Zinc Leaching Process - Sulphidic zinc concentrate usually also includes small amounts of rare metals such as indium and gallium. If the content of these metals in the raw material is sufficiently high, their recovery may be economically worthwhile. In the method according to the invention the recovery of indium and other desirable rare metals takes place in a zinc leaching process, in which at least part of the sulphidic concentrate is leached directly without roasting. | 11-06-2008 |
