Title: Improved pump
Inventor: SUSMAN HECTOR FILIPPUS ALEXAND
IPC: F04C14/02
Filed: 2000-06-16
Abstract: There is disclosed an improved pump (5, 5') particularly suitable for use in a method of "artificial lift" in an oil/gas well. Known pumps used in artificial lift methods suffer from a number of problems/disadvantages - e.g. low efficiency (hydraulic efficiency). The disclosed embodiments of the invention provide a pump (5, 5') which provides a positive displacement of a predetermined volume of well production fluid for each operative cycle of the pump - in contra-distinction known to pumps which provide axial flow of well production fluid. The inventive pump (5, 5') provides a chamber (10, 10') having a volume (V, V'), an inlet (15) to the chamber (10, 10'), an outlet (20) from the chamber (10, 10'), and means for varying the volume (V, V') of the chamber (10, 10'). The means for varying the volume (V, V') of the chamber (10, 10') is controlled by relative rotation of first and second bodies (30, 35; 30', 35').

Title: Trigger arrangement of paintball markers
Inventor: RICE JOHN RONALD
IPC: F41B11/00
Filed: 2002-01-15
Abstract: A paintball marker (Fig 1) comprises a main body (10), a barrel (12) defining a firing axis X - X, a feed port (18), a propellant port (16), and a grip frame assembly 14 including a frame (26) and a trigger 22 pivotably mounted in the frame (26). The trigger has an upper finger engaging portion 50 and a lower finger engaging portion 52 so that it can be operated by two fingers 54, 56. The lower finger engaging portion 52 is curved round so that its finger engaging surface 66 ends in a horizontal part 68. The pivot axis of the trigger is adjustable between a number of positions, one of which is offset to the rear of the finger engaging portions 50, 52 so that the trigger can be operated by pulling downwards on the horizontal part 68 of the finger engaging surface 66, when in use. Movement of trigger 22 about one of selected pivots 80,82,84 causes the forwardly biased spring 88 to move backwards, activating the firing mechanism via contact between microswitch 90 (within grip 20) and the activation portion 46 of trigger 22.

Title: A mobile communication scheduling system which overcomes the problems of time difference and erroneous date and time setting
Inventor: NAGASHIMA YOSHIHISA
IPC: H04M1/72451
Filed: 2002-05-22
Abstract: Mobile communication terminals are able to exchange speech, electronic mail and manage scheduling which is useful to business when arranging meetings between users. Operable in synchronism with a current set date and time set by a user, each mobile communication terminal (101-104) has a registering function of registering schedule data (601-604) including a received schedule date and time received from base stations (201-204) and a notifying function of notifying the user of the schedule data when the current set date and time comes to a registered schedule date and time. Each motile communication terminal corrects the received schedule date and time (611) on the basis of a current reference date and time (631) and the current set date and time (801) on receiving the schedule data to obtain the registered schedule date and time (611'). Each mobile communication terminal may receive information indicative of the current reference date and time from the base station with it added to the schedule data.

Title: Monitoring tyre pressure on board a vehicle
Inventor: TANG QINGFENG
IPC: B60C23/04
Filed: 2002-10-09
Abstract: A system (10) and method for monitoring vehicle (12) tire (14) pressure. A tire monitor (16) for each tire (14) includes a pressure sensor (17) for sensing tire (14) pressure and a transmitter (18) for transmitting a signal (20) representative of the sensed tire (14) pressure. A receiver (22) for mounting on the vehicle (12) receives the tire pressure signals (20). The transmitters (18) and the receiver (22) utilize code division multiple access (CDMA) for the tire pressure signals (20) so that tire pressure signals (20) transmitted simultaneously by the transmitters (18) can be received by the receiver (22). A controller (24) for mounting on the vehicle (12) communicates with the receiver (22) and collects and processes the tire pressure signals (20), and generates control signals for use in conveying tire pressure information to a vehicle occupant. The use of a spread spectrum communication technique such as CDMA reduces interference between tyre pressure monitors on different vehicles.

Title: Dynamic allocation of network resources in a multiple-user communication system
Inventor: BOSE PRATIK
IPC: H04L12/24
Filed: 2001-08-17
Abstract: In a multiple-user network communication system such as a satellite-based system, or in cable or wireless systems, the system resources, such as bandwidth, code allocation, and or slot timing, are allocated to users based in part on their class of service. The allocation provides for immediate allocation of the requested resources to a user having a verified high class of service so long as the resources are abatable or can be made available by tapping a resource reserve. If only a portion of the requested resources are available, they are made available immediately. From time to time, the resources available to at least one class of service are allocated among the users of that class of service, either equally, equally up to the requested resources, equitably, or in some systematic manner.

Title: Converting copy control information to be recognisable by a recorder
Inventor: ICHIMURA GEN
IPC: H04N7/081
Filed: 2003-09-09
Abstract: Copy control information is separated from input packetised audio/visual content data, analysed and, when necessary, replaced with information which can be accepted by a data recorder, then added to the content data to regenerate packet data which is output on a communication bus. A wider range of copy control options (Type 1 - Type 6) can be processed than the set (Type 1 - Type 3) which is implemented on the recorder. If options Type 1 - Type 3 are recognised the same packet data can be output, without replacing the copy control information. If option Type 4 is identified the copy control information is replaced with Type 3 until a predetermined time has elapsed whereupon it can be replaced with Type 2 or Type 1. If option Type 5 is detected the number of times that the data has been copied is stored and the copy control information is replaced with Type 2 until the number of copies exceeds a predetermined number whereupon it is replaced with Type 3. If Type 6 is detected license conditions may be received from a communication network such as the internet and appropriate options Type 1 - Type 3 are substituted for Type 6. A license may stipulate that only compressed data may be recorded whereupon compression is applied to the content before recording is allowed.

Title: Partitioning network data services amongst multiple subscribers
Inventor: WILS JORIS J
IPC: H04L12/14
Filed: 2002-04-18
Abstract: In order to partition network data services amongst a plurality of subscribers, each requesting access to a plurality of data services, at least one session is defined for each of the subscribers, during which session requests can be made. Each subscriber has a quality of service guarantee relating to the fraction of capacity which will be allocated to the subscriber's sessions and a quality of service metric is recorded, relating to the fraction of the subscriber's allocated capacity that has been used. A throughput metric (eg number of bytes to read/write, or number of basic file system operations required to service a request) is combined with an ordered list structure to order sessions based upon their associated metrics. At least one active session list and one inactive list are defined for each subscriber and the active lists are used to determine those sessions that are next eligible to be serviced. When an eligible session is selected for service, its pending requests are serviced in turn either until its associated group, subscriber or session limit has been reached, or until it has no requests left to be serviced, following which the next session on the list is selected.
