  • Patent number: 9358745
    Abstract: A compactor can include a first sidewall, a second sidewall, and a bottom wall, which define a receptacle. The compactor can further include a ram assembly positioned with the receptacle and coupled to a drive assembly. The compactor can further include a frame having a lower longitudinal support member extending between the first sidewall and the second sidewall and an upper longitudinal support member extending between the first sidewall and the second sidewall at the top of the receptacle. A continuous, unobstructed opening is defined between the upper longitudinal support member and the lower longitudinal support member, and a removable cover can be fastened to the frame to overlap the continuous, unobstructed opening.

  • Patent number: 8633240
    Abstract: Novel paclitaxel trihydrates. The paclitaxel trihydrates described herein are obtained by recrystallizing paclitaxel from a water/alcohol solution. Such recrystallization is known in the art to yield the one previously known paclitaxel crystalline trihydrate polymorph. Formation of the novel paclitaxel trihydrates described herein is induced by subjecting paclitaxel trihydrate crystals to an elevated pressure. As evidenced by NMR spectra, the novel paclitaxel trihydrates described herein have three-dimensional structures and/or water coordination geometry structures that are distinct from any previously known paclitaxel trihydrate.

  • Patent number: 4619602
    Abstract: The present invention is an electronically controlled, automatically operated flue damper mechanism which is totally fail safe in operation. The mechanism is to be fitted within the draft hood of a thermostatically controlled heating device such as a gas or oil fired furnace. The electronic control circuitry of the damper being integrated with that of the heating device to which it is fitted. The action of the damper being to close the flue a sufficient time after combustion has stopped, to allow all noxious gases from combustion to have left the flue, and to open the flue before combustion can begin.
