Patent GB-2352489-A (GB)
Title: Tee Connection to a pipeline
Inventor: JOHNSON LEIGH MARTIN
IPC: F16L55/175
Filed: 2000-04-28
Abstract: A method is provided for securing a branch assembly (1, Figure 1) to a "live" pipeline 6. An upper part 2 of the assembly incorporating the branch 13 is positioned on the pipeline over a containment ring 16 located on the pipeline and within which there is an annular seal 17 surrounding an area (6a, figure 2) from which the branch is to extend. A lower part 3 of the assembly is positioned on the pipeline beneath the upper part and the two parts are secured together so that the seal is compressed and an annular space (19, figure 4) is left between the two parts and the external surface of the pipeline. The thickness of this annular space may be adjusted using jacks 18, which may be hydraulically operated (see figures 5 and 6). Grout is injected into the annular space and cures to bond the two parts forming the branch assembly in position on the pipeline. The use of grout avoids having to use welding techniques on a "live" pipeline. A coupon can be cut out of the pipeline, via the access through the branch.

Title: Determining mobile device capability
Inventor: BOSCOVIC DRAGAN
IPC: H04W88/06
Filed: 2000-10-24
Abstract: A telecommunications system comprising several Radio Access Networks 1, 2 linked to a central controller 3 receives registration signals from multi-mode mobile devices 4, 5 over Random Access Channels (RACH). By measuring the elapsed time between registrations with each network 1, 2 and comparing this with a pre-set value, the central controller 3 can deduce whether a given mobile device 4, 5 has the capability to operate on both networks 1, 2 simultaneously or just one at a time. Further embodiments allow re-registration of additional, acquired capabilities of a mobile device 4, 5. As the system 3 has knowledge of the capabilities of each mobile device 4, 5 in its coverage area, this facilitates more efficient use of the system's resources.

Title: Materials introduced by lance into furnace
Inventor: DAVIDSON IAN
IPC: F27D3/10
Filed: 2001-01-17
Abstract: The invention relates to the manufacture of metal in a furnace 14 and to the addition of materials into the furnace in an improved manner. The materials which are required to be introduced for the manufacturing process are calculated and appropriate quantities discharged into a number of hoppers 16 or cavities. Control system and movement means can be provided to allow the selective discharge of materials from the hoppers or cavities at required stages during the manufacturing process and the same are then discharged into the furnace via a lance 8. The system allows the controlled and measured discharge of the material rather than the conventional approach of shovelling or otherwise manually moving the materials into the furnace which can be dangerous and also inefficient in terms of the required materials being provided.

Patent GB-2360633-A (GB)
Title: Switch apparatus
Inventor: OHGIMOTO TAKAO
IPC: H01H15/04
Filed: 2001-03-02
Abstract: Auxiliary fixed contacts electrically connected to a fixed contact of other lanes are provided in blank areas which resides in shift positions to which a sliding contact member 20 is positioned and in which the fixed contact 15-19 corresponding to the lane of first to fifth lanes is absent. Since the auxiliary fixed contacts 15a-19a are provided in the portions of the blank areas in which the contact parts 21-25 have passed over conventionally, the contact parts 21-25 will also make contact with the auxiliary fixed contacts. As a result of this, for example, in a "P" position, in case that chattering occurs between a fixed contact 15-19 and the contact part 21-25, a predetermined signal can be obtained as long as the auxiliary fixed contact 15a-19a makes contact with the sliding contact 20.

Title: Air curtain fan driving device and method for a refrigerator
Inventor: JEONG JAE-YOUK
IPC: F25D17/06
Filed: 1998-12-17
Abstract: A temperature setting part (300) sets a reference temperature of the interior of a refrigerating compartment of a refrigerator. A door opening/closing detection part (304) detects opening and closing of a door of the refrigerating compartment. First and second temperature detecting parts (306, 308) detect the interior and exterior temperatures of the refrigerating compartment respectively. An air curtain fan driving part (312) drives an air curtain fan. A control part (300) performs a normal cooling operation to control the interior temperature of the refrigerating compartment by driving the cooling fan (314) when the interior temperature is under a reference temperature, drives the air curtain fan (316) with each of the numbers of rotations corresponding to each of several temperature ranges, and performs the normal cooling operation by stopping the driving of the air curtain fan if the closing of the door of the refrigerating compartment is detected. Cooling efficiency and electric power efficiency are enhanced by efficiently driving the air curtain fan (316) according to the interior and exterior conditions of the refrigerating compartment.

Title: Cooling stators in induction machines with high magnetic flux density
Inventor: LE FLEM GRAHAM
IPC: H02K3/47
Filed: 2001-06-27
Abstract: A stator 5 for a high power density electrical machine 2 with an air gap winding comprises an outer annular laminated iron stator core 14, a stator winding 13 and support teeth 20A, 20B. The winding 13 comprises a plurality of coils having linear conductor portions 16 extending substantially parallel to the longitudinal axis C of the machine.

Title: System for controlling the running of an assembly carrying vehicle
Inventor: UNOSE NORIYUKI
IPC: G05B19/418
Filed: 2000-07-27
Abstract: The system includes a plurality of assembly carrying vehicles 300 running on an orbit 400. Position indicator members 402 are provided along the orbit. Each vehicle 300 carries a position indicator member detector 362, and a running distance measuring unit 350. The running distance unit measures either the running distance of the vehicle from a start point on the orbit to its present position, or the running distance from one position indication member to the next position indication member. The measurements are made from the number of revolutions of a motor driving a wheel of the vehicle. Each of the vehicles has an operation table which stores data of operations to be executed by the vehicle, preferably linked to running distance along the orbit. The relevant data is selected according to distance determined, and the relevant operation is performed. Fault conditions are generated when the determined running distance differs from the location of a detected position indicator marker by mor than a predetermined amount, and a central control apparatus may signal all vehicles to stop under such fault conditions.

Title: Learning method
Inventor: VAUGHAN WILLIAM JR
IPC: G09B7/02
Filed: 2001-03-23
Abstract: A learning method to enhance long-term retention of a large number of learned facts or principles. The method presents items to a User repeatedly and, depending on the recall of the User, the time between presentations of a properly recalled item increases. Items being presented for the first time and those presented a subsequent time before being properly answered are designated Unseen Items and 0-Level Items, respectively. During each Session, a raw score is assigned to the item (related to the User's ability of recall with the item). When its raw score becomes sufficiently high, the item is considered a P-Level Item, after which it is presented less frequently and the rate of presentation continually decreases as the User demonstrates that he or she knows the correct response for the particular P-Level Item. The number of Sessions that are skipped before the particular P-Level item is re-presented to the User is based on the User's Level L in recalling the correct answer to the item. In this way, known items are repeatedly presented to the User with an ever-increasing interval between presentations. If the User fails to recall the item, the Level of the item is decremented and the time to next presentation decreased. As the User is working with this method, the progress of the User is recorded in a form available for review.
