Abstract: A distributed database system for handling transactions from multiple client systems. A database node receives a request to execute a transaction from a first client, involving a record modification. This record has an associated check-and-set (CAS) value that changes with modifications. The record is sent to the first client, which identifies the CAS value. Similarly, a second client sends a request for another transaction, receives the record, and identifies the CAS value. One of these clients attempts to stage a mutation based on their transaction. This includes sending the previously received CAS value. The system checks for a CAS value mismatch, indicating a conflicting mutation from another transaction. If a mismatch is detected, the transaction attempt is aborted to prevent conflicts. Otherwise, the mutation is staged, and the CAS value is updated.

Abstract: An apparatus comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: receive a user input; and based on the user input, provide an open instance of a first camera control application on a first apparatus as a corresponding open instance of an at least related camera control application on a second apparatus.

Abstract: Various methods are provided for enabling one or more tasks to be chained together, such that a user interacting with a user interface may scroll, back step or otherwise navigate through the one or more tasks in the task chain that may cross one or more software packages. One example method may include causing a first task of one or more tasks on a task chain to be displayed in a user interface. A method may further include determining, in response to a user interaction with the user interface, a second task of the one or more tasks on the task chain to be displayed in the user interface. A method may further include causing the second task to be in displayed in the user interface.

Abstract: A method for separating a substance such as a hydrocarbon from a particulate material such as soil is provided. An aqueous slurry is formed and a shear force is applied to the slurry, such as in a reversible helical screw conveyor, while the slurry is vibrated. The substance thus separated can then be removed from the particulate material.

Abstract: A method and apparatus for continuously pressure decatising a fabric include a rotatable drum (12) around which an endless belt (15) is arranged to travel for conveying a fabric (19) (and optionally a moisture laden textile (20)) between the facing surfaces of the belt (15) and the drum (12). The drum (12) is heated and fabric (19) is pressed between the belt and the drum as it is conveyed through the apparatus. The fabric (19) is subjected to pressurized saturated steam, which may be generated by evaporation of the moisture in textile (20) when it contacts the heated drum, as it is pressed. Various options other than use of a moisture laden textile (20) for supplying the steam are disclosed. The invention involves enclosing the drum in a pressure vessel (14) within which a compressed air atmosphere at ambient temperature is maintained.

Abstract: Apparatus for twisting a travelling strand includes a rotary structure rotatable about a rotational axis X--X and a series of pulleys mounted on the structure in an array disposed about the rotational axis X--X with each pulley in the series mounted on the structure for rotation about an individual axis of pulley rotation which is generally parallel to the axis X--X and moves around that axis on rotation of the structure. An input strand guide pulley guides an input strand to be twisted onto a path in which it will successively engage the pulleys and a strand exit guide pulley guides the strand from that path into an exit path along the axis X--X. The rotary structure is driven through a drive shaft and the pulleys are rotated by gearing.

Abstract: A vehicle rear window heater control comprises a touch switch, a bistable circuit driven between its two states by the touch switch, a relay operated by the bistable circuit so that the heater is controlled by the touch switch and a monostable circuit triggered by the relay for switching off the bistable a predetermined time after the touch switch has been actuated to energize the heater.
