Abstract: A method of locating objects in a distributed electronic environment comprising defining a plurality of object-types, which object-types are assigned a plurality of attributes, one attribute being an object-precedence attribute. A plurality of home locations for objects are defined. When a new object is instantiated, which object has associations with other objects, the new object is located at the home location of the existing object which has the highest precedence value of all the associated objects.

Abstract: A method of recovering the state of a system, which system comprises at least one counter, which counter represents an instantaneous state of an entity in a system. The counter will increase in value in response to an increment request and decrease in value in response to a decrement request, wherein each increment request is paired with a decrement request.

Abstract: A method of management of concurrent sessions within a networked electronic system across multiple servers generally comprises defining a model of the system to be managed, and then defining policies, which policies are applicable to components of the model. Then, system components are modelled as entities in the model with hierarchical relationships between the entities. The entities each comprise a single physical or non-physical object in the system. The model is split into parts such that policy information for a given entity is held on a nominated server, with other servers being informed of where to find the policy information, determination of which policies to apply to a given request being made by a policy checker, which policies are then executed.

Abstract: A variable speed transmission apparatus is disclosed for controlling the rotational speed of a fountain roller in an offset printing press. The apparatus includes a mounting plate adapted to be mounted about the shaft of the fountain roller. A screw mechanism is mounted on the mounting plate and has a sliding block or nut for controlling the position of a first link of a two-bar linkage having a common pivot axis connected to a reciprocating drive in the printing press. The second link of the two-bar linkage is pivotally coupled to oscillate a drive crank with a one-way bearing mounted on the fountain roller shaft. Changing the position of the first bar of the two-bar linkage gives infinitely variable adjustment of the oscillating motion of the crank and thus the rotation of the fountain roller. All of the components being mounted relative to a single mounting plate, the apparatus can be retrofitted to existing fountain roller equipment.
