Title: Management of artifacts in collaborative software development
Inventor: BUCHWALD JAN PAUL
IPC: G06Q10/00
Filed: 2009-01-19
Abstract: Development tasks for new software in a multi-user computing programming environment are managed in a workflow server system and distributed between workflow clients associated with a respective software developer. Each task has a task identifier, and each task uses a respective set of software artifacts as common data inputs. Each version of the software artefacts is managed in a versioning system. Each software artifact has an artifact identifier. For each task, the task identifier is associated with artifact identifiers of the respective set of input artifacts. In response to determining that a software artifact is changed in the versioning system, a set of tasks that use the changed software artifact as a shared input is determined and corresponding revisioning tasks are generated in order to notify programmers that parts of the program need to be revised due to changed input. A change tracker client may be used, and the revision message may lead to a develop accepting or rejecting a change.

Title: Rotating filter
Inventor: TULIE GARY
IPC: A01D44/00
Filed: 2009-09-28
Abstract: A rotating filter comprising a filter on a vertical axis for separating particles from a liquid. The filter may consist of a stack of conical settlement filters with circular concentric ridges 6 to collect algae from water. The water may enter the filter at one point 1 on its circumference, flow across the radius of the cone and drain off the filter leaving behind concentrated algae trapped by the ridges. Preferably a vacuum system 3 is used to suck up the algae which settle on the filter thereby collecting a small volume of concentrated algae which can be processed without centrifuging a huge volume of water. Advantageously the process has relatively modest capital cost and greatly reduces energy requirements and in this way, it seeks to speed up the process of utilizing algae as a major source of food, animal feed, fuel oil and fine chemicals.

Title: Power braking system with steering assist
Inventor: BRENNINGER MARTIN
IPC: B60T8/24
Filed: 2009-12-08
Abstract: A vehicle braking system has separate left and right brakes 11, 12 operable from a source of pressurised fluid 13 via relay valve 16 controlled by separate left and right brake pedals 14, 15 to provide steering assistance during a turn. The relay valve 16 delivers a brake pressure proportional to the depression of the associated brake pedal 14, 15 to separate left and right shift valves 17, 18 so that when each pedal is operated the associated shift valve 17,18 is opened by the respective pilot line pressure to supply the proportional pressure to the respective brake 11, 12. The relay valve 16 is a single valve that supplies both shift valves and the pilot lines 19, 20 are connected by a shuttle valve 21, 22 so that the highest pilot pressure generate by operating the brake pedals 14, 15 is applied to the relay valve 16 so that each shift valve receives the same brake pressure proportional to the highest pilot pressure. This ensures that when both brake pedals are operated unintentional steering/yaw is not introduced to the system.

Title: Process for cutting a block using a planar array of wires
Inventor: GJERSTAD OIVIND
IPC: B23D57/00
Filed: 2009-12-30
Abstract: Process for cutting a block of material 12 into a multiplicity of wafers by movement of a planar array of parallel wires 14 relative to the block (or vice versa) in a direction perpendicular to the plane of the wires. Before the application of a slurry or fluid, the array of wires is brought into contact with the block in a dry condition, in order to introduce a bow in the array of wires caused by a contact pressure between the wires and the block, and thereby keeping the array of wires against the block in their intended positions. Preferably, the block is formed with chamfers on its corners first contacted by the array of wires. The wires of the array may be kept in position by regular equally spaced guide indentations formed on the corner of the block. Preferably, the bow in the wires is introduced before the start up of the wires.
