Abstract: A method of operating a quadrupole device is disclosed. The method comprises operating the quadrupole device in a first mode of operation, wherein ions within a first mass to charge ratio range are selected and/or transmitted by the quadrupole device, and operating the quadrupole device in a second mode of operation, wherein ions within a second different mass to charge ratio range are selected and/or transmitted by the quadrupole device. In the first mode of operation, the quadrupole device is operated in a normal mode of operation wherein a main drive voltage is applied to the quadrupole device, or in a first X-band or Y-band mode of operation wherein a main drive voltage and two or more auxiliary drive voltages are applied to the quadrupole device. In the second mode of operation, the quadrupole device is operated in a second X-band or Y-band mode of operation wherein a main drive voltage and two or more auxiliary drive voltages are applied to the quadrupole device.

Abstract: A self-drilling fastener for attaching wood substrates to metal substrates comprises an elongate shank defining an axis, the shank having a first end and a second end. A drilling tip having a drill point and an axial length is formed at the first end. A broad head is formed at the second end. The shank includes a threaded portion and an unthreaded portion. The threaded portion axially extends from the drilling tip towards the head and includes helical threads and has an axial length, a root diameter, and a thread diameter. The length of the threaded portion is greater than the length of the drilling tip. The unthreaded portion axially extends from the threaded portion to the head and has an axial length and a diameter. The length of the unthreaded portion is substantially greater than the length of the threaded portion and the diameter of the unthreaded portion is smaller than the thread diameter of the threaded portion.

Abstract: In a machine for dispensing stackable roofing washers individually and for driving fasteners through such washers, a shuttle is actuatable to displace a lowermost washer of one from a stack, either a small, circular or large, square washer. A gate is biased toward a lowermost position wherein it provides sufficient clearance for the lowermost washer but not any overlying washer to pass beneath it. A pawl mounted pivotally to the gate is biased to a lowermost position wherein the pawl engages a small washer displaced by the shuttle so as to restrain it against backward movement. A stop is adjustable so as to limit movement of a washer of whichever size is being displaced. A measuring bar is mounted via the stop. A screw gun, which provides a primary handle, and a secondary handle are mounted to an upright element so as to be independently adjustable.
