Patent GB-2466914-A (GB)
Title: Water treatment apparatus
Inventor: GAFFEY PHILIP
IPC: C02F1/68
Filed: 2008-10-15
Abstract: A water treatment apparatus (1) comprises a vessel (2) that defines a chamber (3) adapted to contain a water treatment chemical (4) over which a dosing liquid can flow from an inlet (6) to form a dosing reservoir (8) at the bottom of the vessel (2). A supply (5) of dosing liquid is connected to the inlet (6) of the vessel (2). The interior of the vessel (2) communicates with a conduit (9) along which an entraining pressurized flow of water can be fed for treatment and via an opening (10) in the conduit (9) that is connected to a bottom outlet (11) of the vessel (2). A venturi (12) is located in the conduit (9) adjacent the opening (10) so that the velocity of the pressurized water is increased as it passes over the opening (10) and entrains a dosing stream from the dosing reservoir (8) into the pressurized flow. The venturi (12) also applies suction to the interior of the vessel (2), which draws dosing liquid into the vessel (2) from the supply (5). In this way, the production of the dosing stream takes place under negative pressure conditions so that if the integrity of the vessel (2) is compromised during operation, the flow of dosing liquid into the vessel (2) will immediately cease and there can be no pressure build-up within the vessel (2) of dangerous fumes.

Title: Electric control of an anti-stall tool
Inventor: MOCK PHILIP WAYNE
IPC: E21B44/02
Filed: 2011-10-12
Abstract: An anti-stall tool 58 in an oil well drilling assembly controls reciprocation of the drill bit by an electrical controller that alters weight-on-bit (WOB) depending upon measured downhole pressure or torque at the downhole motor. The electrical controller receives preset high and low working pressure limits for the downhole motor and activates a hydraulic valve system 60,62 to keep the drill bit rotating by maintaining WOB during normal drilling operations, increasing WOB if sensed working pressure indicates that drill bit loading or torque is undesirably low, and reversing WOB by retracting the drill bit if excessive working pressure or torque is sensed. The electrical controller may comprise an electronics package 64 which receives signals from a pressure transducer 68 and controls a pilot valve 60 via an electric downhole motor 64.

Title: Reducing turbo lag in a compression ignition engine by combusting a secondary fuel in the exhaust system upstream of the turbine
Inventor: ALONSO MARCOS
IPC: F02B37/20
Filed: 2011-12-21
Abstract: A turbo lag reduction system 38 for a compression ignition engine includes a system 44 for delivering a secondary fuel 40 directly into the exhaust system 20 upstream of a turbocharger turbine 30. The secondary fuel is combusted in exhaust system 20 to accelerate the exhaust gases and to drive turbine 30. This spools up the turbine to deliver compressed intake air. The secondary fuel, e.g. urea, is different from the primary diesel fuel; and is combusted only during certain operating conditions, such as during engine idle, when the vehicle is about to accelerate. Injection of secondary fuel may be triggered by driver input; by selection of a gear and/or disengagement of the clutch; or where a traffic signal recognition camera is fitted to the vehicle, by detection of an amber or green light; or by any other selected method.
Patent GB-2487022-A (GB)
Title: Steerable bit
Inventor: SIHLER JOACHIM
IPC: E21B7/06
Filed: 2012-04-10
Abstract: Steerable drilling systems for facilitating drilling according to a prescribed, three-dimensional trajectory arc. Steering may be achieved using passive actuators which require little or no power. For example, damping elements 210 which couple a drill bit to a drill collar can be used to tilt the drill bit with respect to the drill collar. Alternatively, rotary cutting (702, fig 7) elements disposed on the drill bit may be used to control the force between the drill bit and the formation at different axial locations. The passive elements used to control the tilt or rotation of the rotary cutting elements are actuated. in a certain pattern, e.g., geostationary, in order to achieve; a desired deviation of the well bore while drilling ahead. One way to achieve this is through the use of field-sensitive materials, e.g. magnetorheological (MR) fluids, that change viscosity in response to an applied magnetic field.

Title: Camshaft with detachable bearing journals
Inventor: GUSTAFSSON REINE
IPC: F01L1/047
Filed: 2011-05-11
Abstract: The invention relates to a camshaft for a small internal combustion engine used in for example cars or motorbikes, it is characterized by being divided into two or more components, preferably it is the camshaft bearing journals (3) on the camshaft that are separate components. With a camshaft in one piece the camshaft lobes (4) cannot have a larger radius than the camshaft bearing journals (3) if the camshaft is to be inserted through the camshaft support bearings (2) in the engine. The bearing journals (3) will then limit the design and height of the camshaft lobes (4). By designing the camshaft divided in separate components to be assembled at the same time or after the camshaft has been inserted into the engine, it is possible to insert the camshaft radially displaced through the camshaft support bearings (2). This makes it possible to design the camshaft lobes (4) larger than what would otherwise be possible for given dimension of the support bearings (2). The invention relates to designs where the joining of the camshaft components are made by a joint in the axial center of the camshaft to minimize the influence on the outer dimension of the camshaft. This is extra important on small camshafts divided into separate components, where the design can have a large impact and limit the intended advantages with the design if not done right.

Title: Control arrangement for a superconducting switch for use within a superconducting magnet
Inventor: TWIN ANDREW
IPC: H01F6/00
Filed: 2012-12-20
Abstract: A superconducting switch controller, or a control method, suitable for a superconducting switch 4 connected across a superconducting magnet 2, comprises: a modulated power supply connected to a heater which is controlled such that it is heated to maintain the switch temperature within a predetermined temperature range above the superconducting critical temperature when providing a resistive current path. The controller may modulate the power provided to the heater in accordance with the heat generated in the switch 4 by a change in the magnetic field of the superconducting magnet 2. This heat may be evaluated through a thermal sensor on the switch, the use of previously recorded modelled behaviours or through some other evaluation techniques, to optimize the temperature control of the switch 4. The controller may be integral with the direct current power source 1 of the heater. The heater control may be implemented by a computer with real-time or selected algorithm or PID control operation. The control arrangement may be used during the ramping of a superconducting magnet for NMR or MRI, where the switch has a weak thermal link to the cryogenic cooling system of the magnet.

Title: Consumption control for grid connected micro-generation system
Inventor: FARR MICHAEL ANTHONY
IPC: H02J3/14
Filed: 2013-01-25
Abstract: An AC electrical distribution circuit 6 is connected to receive power from a micro-generation system 4, to provide power to a plurality of loads or consumers 8, including a switchable load, and to receive power from or provide power to a grid or public distribution network 2. The switchable load is switched on to receive excess power from the micro-generation system 4, or switched off to avoid drawing power from the grid 2. The direction of flow of power between the distribution circuit 6 and the grid 2 is determined according to the polarity or phase difference between the current and the voltage at the distribution circuit 6. Signals representing the current and voltage are gated together to generate a control signal for the switchable load. The micro-generation system 4 may use a renewable energy source such as solar power. The switchable load may be a boiler or immersion heater. Additional signals may be used in combination with the first, representing the current and voltage, with inverse polarity to the first signals. Switching may be restricted to when the voltage is close to zero.
