Title: Method and apparatus for the detection and measurement of particulates in molten metal
Inventor: DOUTRE DONALD ALLAN
IPC: G01N33/20
Filed: 1984-02-23
Granted: 1989-06-15
Abstract: The invention provides a new method and apparatus for the detection of non-conductive particulates in molten metals, such as aluminum, gallium, zinc and lead, that can be liquefied and drawn into a suitable refractory container (14). The passage (26) into the container is of very small diameter (about 300 micrometers for aluminum) and it forms part of a current path between two electrodes (24, 29) carrying a current of about 1 to 500 amperes. The path is surrounded by liquid metal which forms an effective Faraday cage screening the path, enabling the passage of a particulate of about 15 micrometers or larger to produce a voltage pulse between the electrodes of greater than 5 microvolts, which is detectable above the inevitable background noise. The size of the pulse gives an indication of the particle size and appropriate measurement and sampling electronically of the pulses gives a rapid evaluation (less than 3 minutes) of the particle size distribution, giving the operator an opportunity of deciding immediately whether or not further cleansing of the metal is required.

Abstract: A game wheel comprising a support base (2), a plurality of identical rollers (3) radially arranged and rotatably resting on the support base (2), and an observation wheel (l) with observation slots (l4). The surface of each roller (3) is divided into several regions marked with different digits, letters or colors, respectively. The observation wheel (l) is provided with several one-way turning protrusions (l5) on the bottom face so as to turn the rollers (3) contacted with the protrusions (l5) when the observation wheel (l) is turned in a clockwise (CW) direction. Conversely, counterclockwise (CCW) rotation of the observation wheel (l) will not turn the rollers(3). Indicating marks (l6) set on the upper face of the observation wheel (l) indicate the positions of the turning protrusions (l5). By CW and CCW rotation of the observation wheel (l), a user may arrange the randomly arrayed digits, letters or colors of the rollers into a uniform or pre-determined pattern.

To improve the handling of the shaver, it is proposed that it be possible for the rotary knob 11 to be pulled out. It is proposed, furthermore, that the blade carrier 6 be attachable on to the free end of a rotary axle 4, whilst the blade carrier 6 can additionally be equipped with a cover cap 16 and with a wire coil. This wire coil can likewise be used for all conventional razor blades and is not restricted to those blade carriers on rotary-head shavers.
