Title: Door closer having an electrically operated valve holding means to prevent a return bias from being applied to a door
Inventor: JEYNES ROGER HENRY
IPC: E05F3/10
Filed: 2008-01-15
Abstract: A door closer includes an anchor assembly 10 for mounting on a door frame, an actuator assembly 30 for mounting within the thickness of a door providing a concealed door closer. The actuator assembly includes an operating member 22 coupled by a link 20 to the anchor assembly and mounted for movement between a retracted position when the door is closed and an extended position when the door is opened. A damper mechanism regulates the closer speed of the door under the action of a resilient biasing force, such as compression springs 45, which biases the operating member in the retracted position. The damping mechanism comprises a cylinder containing fluid divided into first and second chambers 66, 65 by a piston 51. During normal closure of the door, fluid flows from a first chamber 66 to a second chamber 65 via a fluid channel (70, fig.3). A holding mechanism 110 comprising an electrically operated valve is provided which when operated prevents fluid flow from the first chamber 66 to the second chamber 65 and prevents the bias mechanism 45 from driving the operating member toward the retracted position. Whilst the holding mechanism is active the door is not biased closed but instead the door can be freely moved. When deactivated the valve member is preferably biased into the open position. An electromagnet may retain a trigger member against the force of the valve bias to close the valve. A resilient thrust device 90, e.g. leaf spring acting a direction perpendicular to the direction of the operating member, may be provided to exert an additional closing force as the door approaches the closed position. During movement of the operating member to the extended door open position the leaf spring may rise out of a recess 96a in the operating member and move the trigger to close the valve.

Title: Contact-less financial transactions using mobile devices
Inventor: ADAMSON JANUSZ
IPC: G06Q20/00
Filed: 2008-02-06
Abstract: A system. adds peer-to-peer (P2P) contactless financial transactions using a mobile device as a cashless payment device, by adopting open standards. The system also enables remote Card Not Present (CNP) transactions to be assimilated within a device, offering pseudonymity to the user and allowing almost complete customisability. The system involves the provision of real-time contactless financial transactions over a mobile device via either close proximity or remote transmission and reception of data. Using two proximity enabled devices (e.g. two mobile phones) as the means for communicating payment data between the payer of the transaction and the receiver of the transaction, an operating system and identity client software allow the user to select from a range of information cards, (e.g, a Barclaycard VISA, e-wallet or bank account) for use in the transaction, a process to debit and credit the respective information cards, a security component, and a process for uploading the financial transaction(s) to the requisite issuer (e.g. Barclaycard).

Title: Regenerating a diesel particulate filter (DPF) using at least two after-injections
Inventor: CASSANI STEFANO
IPC: F01N9/00
Filed: 2009-08-19
Abstract: A method for regenerating a diesel particulate filter (DPF) located in the exhaust line of a diesel engine comprises injecting an amount of fuel into the combustion chamber by means of least two consecutive after-injection pulses AIP1-AIP3, each of which starts after the piston has passed top dead centre (TDC) but sufficiently near to TDC for the fuel to burn at least partially inside the combustion chamber to produce hot gases which heat the DPF to a temperature at which the accumulated particulates burn off. The after-injection pulses increase the heat released in the combustion chamber compared to a conventional single after-injection. The injection pattern may also include pre-injections I1, I2 and a main injection I3 for normal running and at least one post-injection PI which occurs so late after TDC that the fuel does not combust in the combustion chamber but passes to the diesel oxidation catalyst (DOC) where it is oxidised.

Title: Method and device for measuring the thickness of a dielectric layer
IPC: G01R33/00
Filed: 1971-04-20
Abstract: 1350435 Measuring thickness electrically B ZUMBACH [trading as ZUMBACH ELECTRONIC AUTOMATIC] 20 April 1971 [24 April 1970] 10101/71 Heading G1N In the measurement of the thickness of a dielectric layer on a conductor e.g. cable or waveguide the maximum or minimum measured values from a pick up 1 occurring within a measuring period is stored in a peak memory. In Fig. 1 a four stranded 6 conductor cable is fed past the core 4 of coil 3 of measuring head 1, the core 4 being in contact with or at a predetermined distance from the insulation 5. Variations in thickness of the insulation 5 result in corresponding variations in the output frequency of oscillator 2. After mixing at 8 with reference frequency 7 the difference frequency is fed to frequency discriminator 9 the output from which is fed to peak memory 10 which stores the highest voltage applied to its input over a measuring period as the cable moves past the measuring head 1. Switch 12a is closed to connect the peak memory 10 to memory 13a and indicator 14a after which peak memory 10 is reset by switch 11, and switch 12a opened. The measuring head is then turned from the position shown to the other three coordinate positions in turn and the appropriate switch 12b-12d closed to store the maximum output values of the store 10 during the corresponding measurements, corresponding to minimum insulation thickness. The cable may include a concentric shielding embedded in the insulating material (5), Fig. 2 (not shown). Alternatively the cable may be in the form of a plurality of conductors arranged in a plane within a flat insulating body, Fig. 3 (not shown). In this case the measuring head is moved across the flat body instead of along a generating line as in Fig. 1 and only one memory 13 is employed. The cable may be armoured Fig. 4 (not shown) or sectored, Figs. 5 and 6 (not shown).
