Abstract: A mounting bracket is provided for mounting to an opening in a wall. The mounting bracket is for an electrical box or electrical device such as a switch, plug or fire alarm for mounting the electrical box or device to a wall without the need for an additional mounting structure. The mounting bracket includes a central opening for receiving the electrical device. At least two legs are integrally formed with a face plate of the bracket and bent perpendicular to the face plate to extend into an opening formed in the wall. A pivotal arm is mounted in each leg and coupled to a screw for limited pivotal movement to pivot the arms between a first retracted position and a second extended position to attach the mounting plate to the wall. The screw is rotated to draw the arm toward the face plate to contact the inner surface of the wall and draw the face plate into contact with the outer surface of the wall.

Abstract: A process and an apparatus for measuring the impedance of a capacitive sample and thereby determining the leakage impedance and the loss angle. To suppress the effects of ambient power frequency fields coupling onto the test object, measuring frequencies on either side of the line frequency are imposed onto the test object. The voltage and current are captured using a detection system. These signals are digitised and processed using a computer to determine the real and imaginary voltages and currents at the two test frequencies. These components are then analysed to calculate the leakage impedance and phase angle at the two frequencies. By applying a linear interpolation between the two points, the impedance and loss angle at the line frequency can be measured.

Abstract: A float is used for preparing a density gradient in a parallel-walled vessel. The float has an outer peripheral surface that has a diameter smaller than an inner diameter of an inner surface of the vessel. With the float placed inside the vessel a liquid is introduced onto the float such that the liquid flows around the float between the float and the inner wall of the vessel. The shape and configuration of the float slows the velocity of the liquid such that there is only laminar flow as the liquid contacts other liquid below the float. Elimination of turbulent flow prevents mixing of different liquid introduced into the same vessel thereby forming layers of fluid. Preferably, the vessel is a centrifuge tube. In one embodiment, the outer diameter of the float is large enough to cause capillary action between the float and the inner surface of the centrifuge tube to force liquid to remain between the float and the inner surface of the centrifuge tube.

Abstract: A mounting system for use in an electrical housing or junction box provides a tactile indication to the installer that the housing is properly installed. The mounting system includes a keyhole shaped opening in a wall of the housing. The keyhole-shaped opening has a smaller section dimensioned to receive a shaft of a fastener and larger section to receive the head of the fastener. A neck portion between the smaller and larger sections has a width less than a width of the fastener shaft to provide interference as the fastener slides between the larger and smaller sections. In one embodiment, the neck portion is formed by two flexible arms extending into the opening. The housing is positioned over the head of the mounting member and repositioned so that the shank of the fastener slides between the two arm members. In so doing, the arm members flex outwardly, and then snap back into place after the shank is fully and properly seated in the smaller section of the keyhole shaped opening.
