Title: Rolling cone bit with enhancements in cutter element placement and materials to optimize borehole corner cutting duty
Inventor: PORTWOOD GARY EDWARD
IPC: E21B10/52
Filed: 1997-04-10
Abstract: A rolling cone bit (10) includes a cone cutter (14, 15, 16) having a pair of adjacent rows of cutter elements (70, 80) that are positioned so as to divide the sidewall (5) and bottom hole (7) duty. The wear resistance, hardness and toughness of the cutter elements (70, 80) in the adjacent rows are optimized depending upon the type of cutting the respective rows perform. In most applications, the cutter elements (70) experiencing the sidewall cutting will have cutting surfaces that are more resistant or harder than the cutting surfaces of the cutter elements (80) in the rows experiencing more bottom hole duty. Likewise, the cutter elements (80) exposed to the bottom hole duty will generally be tougher than those (70) experiencing substantial sidewall cutting. The material enhancements include varying the grades of tungsten carbide used in the cutter elements (70, 80) and by selectively employing layers of superhard abrasives, such as PCD or PCBN. The cutter elements (70, 80) may be either inserts or steel teeth.
Patent GB-2323111-A (GB)
Title: A valve
Inventor: HOWLETT PAUL DAVID
IPC: E21B21/10
Filed: 1998-02-04
Abstract: A valve device suitable for use downhole comprising a body member (5) with a channel (15) through which fluid may flow, and a piston member (10) mounted in the body member and movable between two positions, the first of which allows fluid to flow through the channel (15), and the second of which substantially prevents the flow of fluid through the channel (15). The piston member (10) is locked in the open position until a drop-ball (not shown) is dropped on to ball seat (63) to cause a build up of fluid pressure sufficient to break shear pin (61). The piston member (10) is then able to move when a force caused by a pressure drop over a narrow channel section (37) in the channel (15) overcomes biassing spring (51). This movement of the piston member (10) is restricted however to a predetermined cycle by a continuous "J" slot (39) around the circumference of a cylindrical sleeve (35), only closing the valve when key (41) lands in the long travel position (47). This selective blocking of the fluid flow channel increases the fluid pressure above the blocking mechanism, so that pressure testing of the casing, or setting of pressure activated tools in either a casing string or liner string, above the blocking mechanism, can be achieved.

Title: Multimode communication device operable in independent communication systems
Inventor: RABE DUANE C
IPC: H04B1/40
Filed: 1998-05-01
Abstract: A multimode communication device 160 operates in autonomous communication systems 104, 106 which are independent communication systems which have little or no intersystem communication and have no provision for hand off between the systems. The systems may include satellite systems and terrestrial systems and may operate in different frequency ranges. A first transceiver 124 is coupled to an antenna 122 for communication with a first autonomous communication system 104 using the required protocol and frequency and a second transceiver 126 is similarly coupled to the antenna 122 for communication with a second autonomous communication system 106. Some communication resources, eg. antenna 122, synthesizer 132 etc., are shared to reduce cost. Transceiver 126 may be in a detachable module 148 which may comprise a SIM card. The device 160 establishes communication on a first system 104 and in response to a request to communicate on a second system 106, deactivates the first communication and establishes communication on the second system 106. This communication system changeover may involve registering with the second system 106. The request may originate at the device 160 or at the second communication system 106 and may correspond to a scheduled communication time for communication on the second system 106. The device 160 may try to register with as many active systems as possible, establish priority of use for registered systems and inform communication systems of when it is unavailable (figs. 2, 4, 5, 6).
Patent GB-2325069-A (GB)
Title: Providing simultaneous transmission of paging data
Inventor: KIM SUNG HAK
IPC: H04W84/02
Filed: 1998-05-06
Abstract: A paging system provides simultaneous transmission of page data by delaying a one-pulse-per-second reference clock signal from a global positioning system. The reference clock signal (1PPS) from the Global Positioning System (GPS) receiver is input into a plurality of transmitter controllers of the paging system and delayed by 1-X seconds, the value of X being a delay time associated with the transmitter associated with the transmitter controller in question. The page data is sent from the transmitter controllers to the associated transmitters in accordance with the respective delayed clock signals, and transmitted from the plurality of transmitters simultaneously, whereby the simultaneous transmission of page data is synchronised with the reference clock signal from the GPS receiver, notwithstanding the delay time associated with each of the transmitters. To delay the reference clock signal (1PPS), each pulse of it initiates counting of a higher-frequency reference clock, the corresponding delayed signal pulse being produced (and the counter reset to zero) when the count reaches a prespecified value.
Patent GB-2337412-A (GB)
Title: Tone signalling
Inventor: WEBSTER ANDREW JOHN
IPC: H04W84/08
Filed: 1998-05-13
Abstract: A radio receiver determines the validity of a received tone signal by sampling the signal and determining if the result is within a predetermined error of a valid tone signal. In response to a valid tone signal the receiver may connect a speaker and begin communications, otherwise the radio may enter a sleep mode or sample another tone. An invalid tone signal on a number of communication resources for example, channels, is determined more quickly by sampling the tones in a predefined order for a minimum number of cycles. The tone signal may occur in a continuous tone control squelch system (CTCSS) or in a digital private line system.

Title: Interactive educational toys with wireless communication devices
Inventor: BRAY NIGEL SHANE
IPC: A63H30/04
Filed: 1998-08-13
Abstract: Educational toys of the proposed invention comprise a transmitting and receiving toy wherein the transmitting toy is capable of remotely controlling the receiving toy. The transmitting toy comprises a monitoring device which monitors for status changes such as detection of vibration, orientation, ultrasonic or infrared signals and in response, sends out signals containing identification and status- dependent action data. The identification data identifies the receiving toy to be affected whilst the action data tells the toy what action to perform (eg production of movement, sound or light). The transmitting toy sends out a plurality of these signals with a random delay between each transmission, thereby minimising the risk of collisions with other transmitting toys. The receiving toy compares the identification data with one or more stored id's and if it has a predefined relationship with one of the id's, performs the action corresponding to the action data. At least one of the identification data transmitted by the transmitting toy and the stored id's of the receiving toy may be programmed by the user. The receiving toy can be put into a programming mode wherein it listens for the identification data of a nearby transmitting toy and stores that data in its list of stored id's.

Title: Adaptive coder which adjusts the speed with which it switches between possible code schemes based on its output
Inventor: ALLEN JAMES D
IPC: H03M7/30
Filed: 1999-06-02
Abstract: Adaptive coding scheme which can use one of a plurality of codes from a table of codes, in which the speed at which the coder transitions between different codes is adjusted to arrive at a point where the initial bits of the outputs include 1's and 0's equally often, signifying More Probable Symbols (MPS) and Less Probable Symbols (LPS) respectively in the Golomb coding of the embodiment. The coder inspects the initial bits (Stone Age Symbols) of previous output codes and compares them with preset patterns 302 and then adjusts the speed of transition based on this 303/4. This speed value is then used to adjust a pointer 203/204 which indicates a code in the table of codes [Fig. 1]. Hence increasing the speed value means that larger jumps are made in the table and that code transitions occur more frequently. The coder is discussed in association with entropy and run length encoding schemes.
