Abstract: As shown in FIG. 1 there is one embodiment of a fumigation apparatus in the form of a module (8) including a panel (10) which can be positioned in or at an opening of an enclosed space in use to define a fumigation chamber. Fumigant inlet means in the form of an orifice (12) are arranged in the panel (10) to allow a flow of a fumigant directly into the fumigation chamber. A nominal number of mixing fans, in this case two fans (16) and (18), thoroughly circulate gases within the fumigation chamber when operating. The module (8) includes a system control box (14) linked to the fumigant delivery orifice (12) and valve system which functions to control the flow of toxic gas into the fumigation chamber. The panel (10), when positioned in use, is secure against the passage of fumigant and gases by means of an inflatable rubber seal (22) which is located around a lip edge perimeter of the panel (10).

Abstract: A polymeric coating is applied to at least one embolic coil carried in a fixture, at least a portion of said embolic coil being generally vertical and straight. The coil is carried in the fixture during the processing, and may remain in the fixture if desired for further steps of processing.

Abstract: A hand tool has an elongated shank with a handle at one end and a bit holder at the other end, the bit holder including a cylindrical body having a distal end surface and an axis, the body having an axial bore formed in the end surface of non-circular transverse cross section and terminating at an inner end surface. A neodymium permanent magnet is freely received in the bore and retained against the inner end surface by a thin circular retainer, formed of metal or plastic, which is interference-fitted in the bore. Both flat, disk-like and concave, bowl-shaped retainers are disclosed. A shock-absorbing cushion may be disposed between the magnet and the inner end surface of the bore. A bit formed of magnetizable material is mateably received in a socket portion of the bore and retained in place by the magnet. The portion of the bore receiving the magnet may have a different cross section from the socket portion. The magnet may be disposed in an encapsulation which interference fits in the bore.
