| 20110135455 | OIL COOLER - An air-cooled oil cooler for the wall of an air flow passage of a gas turbine engine is provided, the oil cooler allowing improved heat exchange performance to be obtained. This is achieved by: (I) diverting air flow from the inner side of the oil cooler towards the outer side of the oil cooler, (ii) enhancing heat exchange performance at the leading edge of the cooler, and/or (iii) suppressing airflow wake at the trailing edge of the cooler. | 06-09-2011 |
| 20110317740 | HIGH TEMPERATURE MEASUREMENT PROBE - A high temperature measurement probe comprises an elongate probe body having a measuring head which in use is located in a hot fluid flow. The probe further comprises a thermocouple extending along the interior of the probe body to terminate at a temperature-sensing thermocouple junction inside the measuring head. The probe body has internal passages for circulation of a coolant fluid therein. The measuring head contains a channel, one end of the channel forming an inlet for receiving hot fluid from the hot fluid flow and another end of the channel forming an outlet for discharging the hot fluid received at the inlet. Between the inlet and the outlet a section of the channel extends along the length direction of the probe body. The thermocouple runs along the section of the channel with the thermocouple junction proximate the upstream end of the section. | 12-29-2011 |
| 20120027576 | TURBINE STAGE SHROUD SEGMENT - A shroud segment for a turbine stage of a gas turbine engine forms an endwall for the working gas annulus of the stage. The segment also provides a close clearance to the tips of a row of turbine blades which sweep across the segment. In use a leakage flow of the working gas passes through the clearance gap between the blade tips and the segment. The segment has a plurality of cooling holes and respective air feed passages for the cooling holes. The cooling holes are distributed over that part of the gas-washed surface of the segment which is swept by the blade tips. The cooling holes deliver, in use, cooling air which spreads over the gas-washed surface. The feed passages are configured such that the delivered air opposes the leakage flow of the working gas. | 02-02-2012 |
| 20120057961 | TURBINE STAGE SHROUD SEGMENT - A shroud segment for a turbine stage of a gas turbine engine forms an endwall for the working gas annulus of the stage. The segment also provides a close clearance to the tips of a row of turbine blades which sweep across the segment. In use, a mainstream flow of the working gas passes through the passages formed between adjacent turbine blades. The segment has a plurality of cooling holes and respective air feed passages for the cooling holes. The cooling holes are distributed over that part of the gas-washed surface of the segment which is swept by the blade tips. The cooling holes deliver, in use, cooling air which spreads over the gas-washed surface. The feed passages are configured such that the delivered air has swirl directions which are co-directionally aligned with the swirl directions of the mainstream flow at the segment. | 03-08-2012 |

| 20100294207 | ATTACHMENT FOR A VACUUM CLEANING APPLIANCE - An attachment for a vacuum cleaning appliance includes a head having a bristle carrier and a bristle cover. The bristle carrier includes a plurality of bristles and the bristle cover includes a plurality of apertures. The attachment includes a conduit which is connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance, a handle connected to the head, and an actuator which is depressible towards the handle to effect relative movement between the bristle carrier and the bristle cover between a stowed configuration in which the bristles are retracted relative to the bristle cover and a deployed configuration in which the bristles protrude from the bristle cover through the apertures. | 11-25-2010 |
| 20100294208 | ATTACHMENT FOR A VACUUM CLEANING APPLIANCE - A grooming device includes a head and a handle. A first end of the handle is connected to the head, and a second end of the handle is connectable to a vacuum cleaning appliance. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. The device includes an actuator manually operable by a user to effect relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. The handle includes a conduit for conveying an air flow from the head to the second end of the handle. Resilient members are provided for returning the head to the stowed configuration automatically when the actuator is released by the user. In addition to enabling hair or other matter collected between the bristles of the bristle carrier to be readily dislodged from the device, the automatic retraction of the bristles can ensure that the bristles are not exposed when the device is not in use. | 11-25-2010 |
| 20100294209 | ATTACHMENT FOR A VACUUM CLEANING APPLIANCE - An attachment for a vacuum cleaning appliance includes a head and a handle connected to the head. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. A conduit is connectable to a vacuum cleaning appliance for conveying an air flow towards the appliance. The head includes a first suction opening of the conduit and the handle includes a second suction opening of the conduit. An actuator effects relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. | 11-25-2010 |
| 20100294210 | ATTACHMENT FOR A VACUUM CLEANING APPLIANCE - An attachment for a vacuum cleaning appliance includes a head and a handle connected to the head. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. A conduit is connectable to a vacuum cleaning appliance for conveying an air flow from the bristle cover towards the appliance. The head includes a suction opening of the conduit and the handle includes an air bleed into the conduit. An actuator effects relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. A mechanism is provided for controlling the air flow through the air bleed, for example depending on the configuration of the bristle carrier and the bristle cover so that when the head is in its deployed configuration there is a relatively low air flow into the suction opening to prevent the head from being pushed down against, for example, the skin of the pet being groomed, whereas when the head is in its stowed configuration it is preferable to have a relatively high air flow into the suction opening in order to draw the hair collected between the bristles into the conduit. | 11-25-2010 |
