Abstract: Apparatus and a method for use in handling a load includes a load-bearing rope (1, 19), and a mechanism for paying out and recovering the rope (1, 19). There is also a drum (3, 12, 15, 16) for holding a service cable (2, 17) with a length of the service cable (2, 17) extending from the drum (3, 12, 15, 16). A wrapping device rotates the length of service cable (2, 17) around the rope (1, 19) as the rope (1, 19) is payed out to wrap the service cable (2, 17) around the rope (1, 19), and to unwrap the service cable (2, 17) from the rope (1, 19) as the rope is recovered.

Abstract: Method and apparatus for providing a filtered signal which indicates of a flow of fluid to a fluid pressure communication conduit, the flow being dependent upon the pressure of fluid in a chamber. The pressure in the chamber is controlled by one or more pressure adjusting valves. The invention provides for receiving into a data processing module one or more valve signals indicating open states of the pressure adjusting valve or valves, and also a flowrate signal from a flowrate sensor, which represents the real instantaneous flowrate, and it is this signal which needs to be filtered to remove transients. The invention provides for choosing between a first processing mode and a second processing mode for the flowrate signal. The first processing mode is used when the second processing mode is not in effect, and when neither of the valve signals indicates an open valve. The second processing mode is activated a valve signal indicates an open valve.

Abstract: Intermediates and a process for preparing doramectin, the compound of formula (I), semisynthetically from by-product in the fermentation procedure which also yields the compound of formula (I). The intermediates prepared by the process of this invention also have utility as antiparasitic agents. The process of this invention utilizes continuous reaction inert gas sparging during the pyrolysis step, resulting in a significant improvement in the overall yield of this conversion.
