Patent GB-2404888-A (GB)
Title: Cyclone apparatus for a vacuum cleaner
Inventor: NORTH JOHN HERBERT
IPC: B04C5/30
Filed: 2001-07-05
Abstract: Apparatus for separating particles from particle laden air comprises multiple stage separator in which the first stage comprises a generally cylindrical chamber having a hollow central member extending axially from one end thereof with openings in its wall remote from the said one end. Air is drawn tangentially into the chamber near its said one end, the tangential entry in combination with an unapertured wall region of the central member establishing a rotating mass of air, thereby causing heavier than air particles to migrate to the outer regions of the chamber under centrifugal force. Suction is applied to the interior of the central member. The suction force is selected such that particles near the walls of the chamber tend to continue in a generally rotational and axially progressive path into a particle collecting region of the chamber, while relatively particle-free air is drawn radially inwardly, as it progresses axially, so as to exit to a second separation stage, through the openings in the central member wall. Particles separated in the second separation stage enter a particle collecting region. A valve closes the particle collecting region during operation of the separator, so that particles separated out by the second stage are retained in the colleting region until the separation process is complete, at which point the valve opens to allow particles upstream of the valve to pass through into the particle collecting chamber associated with the first separation stage. The valve includes a closure member which moves into contact with a resiliently deformable O-ring seal 82 to close the valve. The resiliently deformable seal allows further movement of the closure with increasing vacuum which moves the closure 74 (or a plate carried thereon 78) closer to the downstream exit of the second separation stage.

Title: Diagnostic method for an energy conversion device
Inventor: COTTRELL BRIAN
IPC: G05B23/02
Filed: 2003-09-23
Abstract: A diagnostic tool for an energy conversion appliance (eg heating, ventilation or air conditioning device, especially a domestic central heating boiler) comprises an sound receiving transducer 2 coupled to a recognition engine 2 and processor 4 to identify and discriminate between the acoustic signatures of different operational events (eg fluid flow noise, mechanical or electromechanical noise) within the operating sequence of the appliance. The measured sound signals are compared with stored data 3 to determine whether an event has occurred in the correct sequence in a plurality of event occurrences by comparing monitored time intervals with stored time intervals indicative of correct functioning of the appliance. The diagnostic tool may be retro-fitted to an existing appliance, and may regularly transmit data via a communication channel 5 to a remote backend computer system. The tool may be used to generate an audible alarm or shut down the appliance if the appliance operates incorrectly.

Title: Magnetic lens focusing module with resilient membrane
Inventor: CHUANG YUN YU
IPC: G02B7/04
Filed: 2006-05-17
Abstract: A focusing module 100 includes a casing 10, at least one fixed magnetic element 20, a membrane 30, a movable magnetic element 40, and a lens 50. The fixed magnetic element is fixed in the casing for generating a first magnetic field. The membrane is received and retained in an upper section of the casing. The membrane defines a central hole 31. The movable magnetic element is attached to the membrane, surrounding the central hole of the membrane. The movable magnetic element receives a control signal and in response thereto generates a second magnetic field, which interacts with the first magnetic field of the fixed magnetic field to induce a force acting on the membrane to cause elastic deformation of the membrane. The lens is fixed to the central hole of the membrane whereby the lens is movable with respect to the casing due to the elastic deformation of the membrane caused by magnetic interaction between the first and second magnetic fields of the fixed and movable magnetic elements so as to effect focusing operation. Magnetic element 40 may be a coil. Central bore 21 and flat lens 111 are shown.

Title: External Desktop Dock for a Cartridge-Based Data Storage Unit
Inventor: MCCORMACK PATRICK
IPC: G11B17/043
Filed: 2006-06-29
Abstract: An external docking station for a removable data storage unit (cartridge 90, figure 4) allows the unit to communicate with a computer system via a standard interface connection, such as a USB connector. The docking station, in a locked or closed mode, locks the removable data storage unit into place via a latch 122. The docking station has an ejection assembly comprising the latch 122 and an eject lever 130 driven by a motor (110, figure 4A) preferably operated by a push button (103, figure 4A). The latch is spring biased into an open position as shown in figure 5C but is held in a closed, cartridge-engaging position by the eject lever 130 when the cartridge is engaged. On ejection, the eject lever 130 first moves to a pre-eject position as shown in figure 5B, where unlatching is achieved, before moving further to the full eject position as shown in figure 5C. This delays ejection of the removable data storage unit until the hard disk drive is no longer in use, thereby preventing possible damage to drive media and/or read-write heads.

The filtering comprises selecting a content item from the first subset in response to the subset characterising data and a second user profile for the first user. The second user profile is more detailed than the first user profile. Improved privacy and security may be achieved as the user profile is distributed over different devices.

Title: Improved cardiomyocyte differentiation
Inventor: MUMMERY CHRISTINE LINDSAY
IPC: A61K35/34
Filed: 2004-06-01
Abstract: The present invention provides a method of enhancing the efficiency of differentiation of hES cells into cardiomyocytes which method comprises incubating the cells under serem free conditions. The method typically includes providing cells that induce cardiomyocyte differentiation by cell to cell contact Differentiation to cardiomyocytes can occur via two routes, namely by spontaneous differentiation and by induced differentiation. Without wishing to be bound by theory, the present inventors hypthesise that, in the case of induced differentiation, END-2 cells, for instance, are needed for aggregation to cause local high cell densities and in inducing differentation of nascent mesodern. This second step could be enhanced in any human embryonic stem cell line leading to the prediction that it will work in lines other than hES. In cell lines that undergo sponantaneous differentiation, it is hypothesised that local induction of embryoid bodies in edoderm occurs. Typically for induced differentiation this method will also comprise culturing the hES cell with a cell excreting at least one cardiomyocyte differentiation inducing factor or with an extracellular medium therefrom, under conditions that induce differentiation.

Title: Wiper pivot and rear wiper device
Inventor: IWATA KENGO
IPC: B60J5/10
Filed: 2007-02-12
Abstract: A wiper pivot enhancing an antitheft effect for a vehicle. In the wiper pivot (12), an installation section (26) of a theft prevention sleeve (24) is installed on a pivot holder (22). This causes a flange-like section (30) of the theft prevention sleeve (24) to face, inside a rear window (54) of a rear boor (42), a pivot hole (56), and also causes an invasion prevention wall (32) to rise from the flange-like section (30) toward the tip side of a pivot shaft (14), positioning the invasion prevention wall (32) close to the pivot hole (56). As a consequence, even if a thief tries to insert an unlocking member (58) such as a wire from the pivot hole (56) toward a locking device to unlock the locking device (44), the invasion of the unlocking member (58) is blocked by the invasion prevention wall (32). The wiper pivot (12) can enhance an antitheft effect for a vehicle (40).
