Abstract:
A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g. -80°C or -135°C) or cryogenic (e.g., about -140°C to -196°C) storage and retrieval system that stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are normally stored within an ultra-low temperature or cryogenic freezer compartment. The tube picking mechanism includes a tube picking chamber that is maintained at about -80°C, about -135°C or at cryogenic temperatures in cryogenic applications. Active electrical and mechanical components are maintained in a compartment above and separate from the refrigerated, ultra-low temperature or cryogenic compartment. Thermal stratification inhibits heat transfer into the lower, ultra- low temperature or cryogenic compartment in which tube picking occurs from the upper compartment in which active electrical and mechanical components are located, and also inhibits heat transfer into the lower, ultra-low temperature or cryogenic compartment via an access door for tube storage racks.

Abstract:
An animal overshoel has a base plate (2) and a plurality of elongate members (4, 6) connected to the base plate. The elongate members (4, 6) are each provided with a formation (22) configured to enable securing of the overshoe to a foot of an animal by an elongate securing member (24) engaging the formations with the elongate members (4, 6) in an upstanding condition with respect to the base plate.
Abstract:
Glycosides, salts, hydrates, solvates, derivatives, analogues, tautomers, isomers and/or racemates thereof and optionally at least one other compound isolatable from a woody perennial, said glycosides and other compound having cardiogenic activity. Cardioactive agents or pharmaceutical or veterinary compositions containing these compounds are disclosed as well as methods of treatment and/or prophylaxis involving these compounds. Verbascoside and geniposidic acid isolated from Eremophila species (native fuchsia) are preferred.
