Abstract: A removal tool is provided. The removal tool includes a tool body extending in a longitudinal direction having an engagement portion at one end and defining an opening at the other end. The engagement portion includes two prongs and defines a notch portion formed between the prongs at a distal end portion. The notch portion extends in the longitudinal direction and rounded at a proximal end portion, each prong has a cut out portion at the distal end portion horizontally tapered toward the notch portion. The distal end portion has a tapered portion vertically tapered away from the distal end portion.

Abstract: A gate valve includes a valve body having a fluid passage for the passage of liquid, sludge and/or fecal matter and a substantially flat slider. The slider is slideable between an opened and a closed position in order to open or block the fluid passage, respectively. The slider includes two opposite straight edges via which the slider is slidably guided in the valve body surrounding it. The slider is substantially made from a plastic material. The slider includes flanges along each of the two opposite straight edges for providing rigidity to the slider.

Abstract: A method and circuit for using signature analysis testing techniques without deriving start/stop and clock signals from the device under test. In this invention, a start signal is derived from the output data stream by configuring that data stream to indicate when the test stream begins. The stop signal is derived by counting the predetermined number of data bit cells to be measured and issuing the stop signal when the count is reached. Data clock pulses are derived as a fraction of test system clock pulses at a frequency approximately equal to the bit cell frequency. The data clock pulse is located at the midpoint of the bit cell time so that the data stream is clocked into the signature analysis tester at a stable point.
