Title: A leaf seal for a rotary machine
Inventor: HOWES NEIL
IPC: F01D11/00
Filed: 2008-07-28
Abstract: A leaf seal 10 in a rotary machine is located between a higher pressure region 14 and a lower pressure region 16 of the machine. Blow-down forces are greater on the lower pressure side 16 of the leaf seal 10 than on its higher pressure side 14, resulting in greater inward deflection of the leaves 20 on the lower pressure side 16 of the seal than on its higher pressure side 14, leading in turn to greater wear of the leaves and the contacting rotor surface 44 on the lower pressure side 16 of the seal. To counteract this, the free ends 36 of the leaves 20 can be given a tapered profile 42 to gradually reduce the length of each leaf 20 over its width 'w' from its higher pressure side 14 to its lower pressure side 16, so that the leaves 20 are free to deflect under the blow-down forces by the amount of their reduction in length (a maximum of 'x'), before they contact the rotor surface. As an alternative to profiling the rotor-contacting ends 36 of the leaves, the leaf-contacting surface 44 of the rotor 12 can be given a tapered profile 46 in a mirror- reversed version of the leaf-end profile 42. The tapered profile of either the free ends 36 of the leaves 20 or the leaf-contacting surface 44 of the rotor 12 can either be linear (42, 46 in Fig. 2) or non-linear (48, 50 in Fig 3).

Title: Common-Rail Pressure Control on Engine Start up.
Inventor: YOSHIDA SEIICHI
IPC: F02D41/06
Filed: 2009-03-25
Abstract: A common rail pressure control apparatus and method; the apparatus comprises an injection valve 30 which injects fuel accumulated in the common rail 20 to an internal combustion engine 2. An opening control unit (S308, S310, fig.6) controls an electric current supplied to a metering valve 16 for manipulating an opening of the metering valve to meter fuel supplied from the supply pump 14 to the common rail and control pressure in the common rail. The opening control unit first sets the opening of the metering valve at a substantially full open state in a starting operation of the internal combustion engine. The opening control unit subsequently switches the opening of the metering valve from the substantially full open state to a predetermined opening, which is smaller than the opening in the substantially full open state, in response to a determination that the switching condition is satisfied. Preferably water and fuel temperatures are taken into consideration for determining a predetermined common-rail pressure which is used for the switching condition.

Patent GB-2468372-A (GB)
Title: Plug lid and base
Inventor: MCBOYLE PETER GRAHAM
IPC: H01R13/502
Filed: 2009-08-19
Abstract: An electrical plug has a space beyond its terminals to allow wires to be pushed through more than normal. The wires can then be trimmed so that only the required length is used in the plug. This may be achieved by having free space 14, 15 on the plug base behind the terminals, and having corresponding projections (10, Fig 3) on the lid of the plug to provide the missing insulation. Alternatively, the plug may have ramps (222, Fig 10a) to direct the wires upward where they can be trimmed, or the terminals of the plug may be mounted on a plate so that they can be uplifted together.

Title: Improvements in or relating to lighting systems
Inventor: HOOD ALASDAIR STUART
IPC: B05B1/34
Filed: 2007-05-31
Abstract: The invention disclosed relates to a light housing adapted to retain a light source. The light housing has a first reflector and a second reflector mounted to rotate concentrically about a main axis. A transmission system is present between the first and second reflector. Rotation of the first reflector in a first direction about the main axis rotates the second reflectors via the transmission system at the same angular velocity as the first reflector about the main axis to retain the same relative angular position between the first and second reflectors. Rotation of the first reflector in a second direction of rotation, opposite to the first direction, rotates the second reflector, via the transmission system to vary the relative angular position between the first and second reflector.

Abstract: 1,175,705. Control circuits therefor ZAKLADY KONSTRUKCYJNO-MECHANIZACYJNE PRZEMYSLU WEGLOWEGO. 4 March, 1967, No. 10344/67. Heading E1P. In a longwall mining installation the automatic collapse, advance and setting of each roof support or of each of consecutive groups of roof supports of the installation is regulated by a control unit 4 associated with each support or each group of supports, the units 4 being spaced along the installation according to the spacing of the supports or groups of supports therealong. A signal, e.g. a collimated gamma radiation beam, from a signal source 8 on the winning machine 3 of the installation is, as the machine passes a unit 4, received by a receiver of the past unit and causes through the receiver activation of means in the unit whereby the unit is connected to a signal transmitting network 5 so that the received signal can now be relayed through the receiver into the network to be picked up by the receivers of such adjacent units as are connected to the network. The receiver of a unit once connected to the network is disconnected from the network and left to pick up a signal directly from the signal source on a subsequent passage of the source past the unit only after the receiver has received a predetermined number of signals from the signal source through the network by way of the receivers of neighbouring activated units. These signals are utilised by the receiver to programme the operating of the associated support or group of supports to cause advance of the adjacent part of the installation thereby. Means for manual override and for manual locking out of that part of a unit's programme controlling the self advance of the associated support or a group of supports are provided in each unit.

Abstract: 591,073. Voltage measurements. HAEFELY & CIE.. AKT.-GES., E. April 26, 1945, No. 10528. Convention date, Sept. 1, 1944. [Class 37] In apparatus for measuring high alternating voltages by means of a capacitative potentiometer, the mean phase difference between the total voltage to be determined and the voltage. measured is compensated by an ohmic resistance inserted in the high voltage part of the potentiometer. A resistance 6 is connected in series, as shown, or in parallel with the H.T. component 1 of a capacitative voltage divider 1, 2. Voltage measurements are taken as a ratio of the H.T. voltage across the secondary of a transformer 4 whose primary is connected through a choke 3 across the L.T. component 2 of the capacitative voltage divider 1 or 2. The resistance 6 produces a phase-shift of the H.T. voltage approximating to that produced in the L.T. measuring circuit under average conditions of impedance burden 5. The ohmic resistance when connected in series has a spark-gap 7 or other protective means against voltage surges.

Abstract: 833,647. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY April 2, 1957 [April 6, 1956], No. 10595/56. Class 39(4). In a gas cooled nuclear reactor, having very high heat release rates at high temperature, the core fuel elements and the reflector blocks are urged together by the cooling gas pressure and are mounted on pivots, at their lower ends, to allow for distortion and growth. The elements are arranged vertically in a central core surrounded by a ring of graphite reflector blocks containing vertical control rods movable in tubes, an outer ring of graphite reflector blocks, a steel cylindrical pressure vessel, a thermal shield comprising a hollow-walled, steel structure the voids in which contain water, and a concrete biological shield. Three separate gas cooling systems are provided, a vertical current of helium through the core, an air flow through the thermal shield, and a gas flow through the central rod tubes. In addition the interior of each core element is vented to a manifold outside the pressure vessel. Charging and discharging are effected through a vertical neck in the pressure vessel above the core. The neck is closed by a rotatable plug through which the elements are engaged by an arm carrying a grapple. Each core fuel element, Fig. 6, consists of an outer graphite tube 50 and a loose fitting inner graphite rod 60 having a helical groove 61. A helical strip 62 of fissile material, diluted with fertile material, is contained in 61, and a spacer 63 at each end of the element constitutes a neutron reflecting member. The graphite of the core may be in the proportion 3000 to 8000 parts by weight to one of the fissile material. The fissile and fertile materials are carburized after wrapping round the plug.
