| 20090056632 | MILKING APPARATUS AND METHOD - The invention relates to apparatus for milking animals such as cows, components of the apparatus and methods of milking animals employing the apparatus. The apparatus comprises at least two resilient membranes having a space therebetween into which the teat of the animal may be inserted. The membranes are held by a support structure under tension in a direction transverse to the direction of insertion of the teat, to protect the teat from excessive force when the membranes fall onto the teat. | 03-05-2009 |

| 20080217082 | Skirt for Air Cushion Vehicle - Skirts for air cushion vehicles that are formed from material that is tensively strengthened in at least one direction, and preferably two different directions, so as to resolve and reduce the axial and radial stresses in the skirt. The material may be strengthened by incorporation of reinforcing cords arranged to reduce the axial and radial stresses in the skirt both when a vehicle comprising such a skirt is static and when it is in motion. | 09-11-2008 |

| 20120096773 | USER ACCESS PORT FOR CONTROLLED ATMOSPHERE APPARATUS - The invention relates to a user access port for a controlled atmosphere apparatus comprising a porthole extending through a wall; a sealing assembly comprising a first sealing means and a second sealing means for maintaining a sealing barrier across the porthole, whereby the first sealing means comprises a first closure member that is adapted to at least substantially seal the porthole when arranged in a closed position and allow user access to the porthole when arranged in an open position; the second sealing means is mounted so as to extend at least substantially across the porthole and comprises a sealed access member and a second closure member, whereby the sealed access member comprises a user access aperture having a peripheral edge adapted to form a sealing contact with an arm of a user when an operator extends his arm through the user access aperture and whereby the second closure member is adapted to at least substantially seal the user access aperture when arranged in a closed position and at least substantially open the user access aperture when arranged in an open position. The invention further relates to a controlled atmosphere apparatus comprising one or more user access ports, a sealing assembly for a user access port and a method of replacing a sealing means of a user access port. | 04-26-2012 |

| 20090140089 | IMPACT CRUSHER - An impact crusher includes a crushing chamber, a rotor mounted in the crushing chamber, and an apron having an impact surface, said apron being movably positioned within the chamber. The apron is pre-loaded to oppose forces generated within the crushing chamber. The apron is free to move away from the rotor in the event that the forces generated within the chamber exceed a predetermined threshold. During normal use, the apron is suspended within the chamber against a mechanical stop, and the apron is free to return to its initial suspended position after the removal of uncrushable material from the chamber. | 06-04-2009 |

| 20080213125 | Apparatus and Method for Using Ozone as a Disinfectant - A method of sterilizing a closed environment is provided in which an ozone generator is placed into the closed environment; it then generates ozone to a predetermined ozone concentration and increases the humidity of the closed environment. The ozone concentration is maintained at the predetermined ozone concentration for a predetermined period of time, and after the period of time has expired, the ozone is depleted. When the ozone concentration is reduced to a predetermined safe level, the ozone generator signals. | 09-04-2008 |
| 20080310992 | APPARATUS AND METHOD FOR USING OZONE AS A DISINFECTANT - A method of sterilizing a closed environment is provided in which a disinfection apparatus is placed into the closed environment; it then generates ozone to a predetermined ozone concentration, following which the humidity of the closed environment is rapidly increased. A catalytic converter then reduces the ozone concentration to safe levels. When the ozone concentration is reduced to a predetermined safe level, the disinfection apparatus signals. | 12-18-2008 |
