Title: Detecting objects of interest in the frames of a video sequence by a distributed human workforce employing a hybrid human/computing arrangement
Inventor: CROSS GEOFFREY MARK TIMOTHY
IPC: G06Q10/06
Filed: 2008-06-12
Abstract: Distributed human workers scrutinize video image frames and process the images to detect and characterize defined objects of interest while ignoring other features. A video data source is configured at a central coordinating server into sets of HITs (Human Intelligence Tasks) comprising sets of frames sampled from the video source. Each HIT is allocated to a particular worker and despatched to their workstation via the Internet. The workers search their allotted frames and, using a computer data entry operation, signify the detection of any objects of interest. Signals signifying object detection are transmitted to the centre and such detections are clustered together into groups associated with an object. Object detection is deemed valid if the number of detections associated with an object reaches a threshold and 3 dimensional location coordinates are then computed for the object. If a predetermined number of detections are not reached by a worker then their HITs are retransmitted to other workers. If the number of HIT presentations exceeds a predetermined maximum then the object detection is deemed invalid.

Title: Heating system
Inventor: FARRELL CHRISTOPHER CHARLES
IPC: F24H8/00
Filed: 2006-10-09
Abstract: The heating system includes a fuel burner 140 in co-operation with a primary heat exchanger 120, a reservoir 170 for storing warmed water in, a blending valve 194, and a controller 200. In use, a user can provide a signal to the controller to warm the water in the reservoir using a heater or the primary heat exchanger. When hot water is required water is removed from the reservoir or is warmed by being passed through the reservoir, and then mixed with water from a cold main 172. This is to obtain a blended target temperature prior to being admitted to a further heat exchanger 190 for heating the water. Liquid entering the reservoir passes through a secondary heat exchanger 150 and is warmed by the secondary heat exchanger. The secondary heat exchanger acts as a thermal store.

Title: Method for the production of powder composite cores and powder composite core
Inventor: BRUNNER MARKUS
IPC: B22F1/08
Filed: 2007-07-11
Abstract: A powder composite core is to be particularly dense and strong while being produced from soft magnetic alloys. In particular, the expansion of the heat-treated core is to be avoided. To produce this core, a strip of a soft magnetic alloy is first comminuted to form particles. The particles are mixed with a first binder having a curing temperature T1,cure and a decomposition temperature T1,decompose and a second binder having a curing temperature T2,cure and a decomposition temperature T2,decompose, wherein T1,cure < T2,cure <= T1,decompose < T2,decompose. The mix is pressed to produce a magnet core while the first binder is cured. The magnet core is then subjected to a heat treatment accompanied by the curing of the second binder at a heat treatment temperature TAnneal > T2,cure.

To raise the hood prior to its closure, the slider is first moved to the position 5d'. After raising and closing the hood its diameter is sufficiently restricted to retain the hood in its raised position. An umbrella may be secured to the bag by a member 9 in conjunction with one or other of straps 9a, 9b according to whether the hood is up or down. The carrying handle 6 passes through a ring 7 when the hood is down, and through a ring 7a when the hood is up, and is then detachably secured, as by a buckle 6b, to the shoulder strap 8. The rings 7, 7a are carried by a strip of metal riveted to the upper ring of the bag.

Abstract: 503,366. Electric signalling systems. GRANAT, E., and COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT. April 4, 1938, No. 10293. Convention date, April 14, 1937. [Class 40 (i)] The landing T-indicator 4 at an airport is operated by a reversible motor 8 under the control of a wind vane 2. The vane and the indicator operate " selsyn " type transmitters 1, 3 which control a differential electric receiver 5 and thereby' operate two cam-operated mercury switches 6 which control the reversing relay 7 of the motor. When lack of correspondence occurs between the positions of the vane and indicator, one or other of the mercury switches is operated and the indicator is driven until the receiver 5 restores the operated switch and coincidence is regained. Independent indicators 30, 31 repeating the positions of the vane and T-indicator are provided at a control point and are operated by receivers 21, 22 under the independent control of the transmitters 1, 3. The T-indicator may be locked in any desired position under the control of an independent transmitter 24 provided at the control point and adapted to be switched into circuit instead of the transmitter 1 by a changeover switch 23. The indicators at the control point are in the form of a pointer and a T respectively, the indicators being associated with separate dials or arranged concentrically on a single dial. An indicator is also provided to repeat the movements of the transmitter 24. The T-indicator may be unclutched from the motor 8 and operated manually by a handle 71. In a modification, the electric differential 5 is replaced by a differential gear located at the T-indicator, the elements of the gear being controlled by the transmitter 1 and the shaft 53 respectively. In this arrangement, a transmitter is also provided at the T-indicator or a control point and may be switched into circuit instead of the transmitter 1 for the purpose of locking the T-indicator in a predetermined position. A lamp may also be provided to indicate when the T-indicator is in the correct locking position.

Title: Improvements in or relating to methods of manufacturing electrical devices
IPC: H01G4/18
Filed: 1957-03-29
Abstract: In a process for manufacturing electrical devices, such as wound capacitors, which comprise metal-foil strips separated by strips of thermoplastic synthetic resin material (e.g. stretched polystyrene) of greater width than the metal-foil strips, air occlusions within the devices are avoided by placing the devices in a vessel which is then evacuated, heating the devices to cause the edges of the thermoplastic strips to fuse together and then applying pressure to the devices while they cool until the thermoplastic material has solidified.  The final step of applying pressure ensures that no cavities remain within the devices after the edges of the thermoplastic material have become sealed together.  The pressure may be applied by a gas under pressure, an oil, preferably one having a high viscosity, or a mechanical device such as a press incorporating standard pressure dies.
