Title: A pontoonless tension leg platform
Inventor: HEIDARI AMIR HOMAYOUN
IPC: B63B35/44
Filed: 2008-07-07
Abstract: A pontoonless tension leg platform 10 (TLP) has a plurality of buoyant columns 16 connected by an above-water deck support structure (22, Fig 2). The tension leg platform is free from subsea pontoons or structural members between the buoyant columns. The buoyancy of the columns may be increased by the addition of subsea sections of increased diameter. A pontoonless TLP has a smaller subsea projected area in both the horizontal and vertical planes than a conventional multi-column TLP of equivalent load-bearing capacity having pontoons between the columns. This reduction in surface area produces a corresponding reduction in the platform's response to ocean currents and wave action and consequently allows the use of smaller and/or less costly mooring systems. The absence of pontoons in a multi-column TLP also has the added benefit of providing an unobstructed path for risers to connect with the deck of the platform.

Title: Distributed transaction processing and committal by a transaction manager
Inventor: FOWLER MATTHEW
IPC: G06F17/30
Filed: 2009-08-12
Abstract: Committal of distributed transactions independently of persistent storage can make the speed advantages of data grid computing available for high volume distributed transactions, without losing the reliability of conventional database systems. The processing system uses a transaction manager to receive change to be made to an in-memory data grid during processing of distributed transaction, and may apply them to a persistent storage memory when messages are received. Conventionally transactions on critical data (e.g. financial information) are processed using a database architecture whereby a persistent database (typically a redundant disk array) comprises the master record. In cases where large amounts of data need to be accessed but absolute safety of data integrity is less critical, for example search engines, processing is conducted on live in-memory data without all the data being backed up, which can be much faster but data can be lost when processors fail. There have been attempts to use data grid architectures with some backup to persistent stores for more important data but these have either introduced disk access bottlenecks or required manual intervention in the event of failure.

Title: Distribution of PSTN derived clock through IP network
Inventor: THAVISRI VIPAPUN
IPC: H04J3/06
Filed: 2009-09-29
Abstract: A node 120 providing a gateway between a PSTN (DS1,BRl) can derive a master clock therefrom and then distribute it to other nodes 130/140 over an IP network. The number of slave nodes directly fed by this master node can be limited such that it does not unduly impact the VolP call carrying capability of the DSPs, a fan-out limit. W hen the limit is reached a slave node 140 can be promoted to provide another clock stratum as a Tandem Clock Source 130 which redistributes clocks to further slave nodes. Slave nodes synchronise their clocks by timing the arrival of a predetermined number of UDP packets and the same number of local clock pulses and adjusting local timing to bring equalise the times. Can be used with Circuit Emulated Services (CES).

Title: Antenna allocation in a MIMO-OFDM system using a combination of bulk and per-tone antenna selection
Inventor: COON JUSTIN
IPC: H04B7/06
Filed: 2009-11-13
Abstract: Antenna allocation or selection in a multi-antenna, multi-carrier wireless communications device can be performed at a receiver or a transmitter of a wireless communications signal. A selection is made of a subset (e.g. TX2 and TX3) of the available antennae, and each antenna from the subset is used for transmission. Each subcarrier is transmitted on only one of the antennas but several different sub-carriers can be transmitted on the same antenna. Thus, it can be said that the antenna selection comprises a combination of bulk and per-tone antenna selection. The antenna selection criterion is preferably based on the optimisation of a performance metric, such as minimisation of BER, or maximisation of SNR.

Title: Switching regulator control circuit for an electric stepper motor
IPC: H02P25/08
Filed: 1975-03-11
Abstract: 1514202 Control of stepper motors TEXAS INSTRUMENTS Inc 11 March 1975 [18 March 1974] 10049/75 Heading H2J A switching regulator control circuit for a multi-coil stepper motor comprises means to selectively provide an enable signal to select each coil; a feedback circuit connected to the selected coil; comparator means, having one input to receive a signal from the feedback circuit and a second input to receive an input signal level, to provide a desired voltage output signal when the feedback signal and the input signal level reach a prescribed difference in magnitude, enabling means connected to receive the enable signals and the output of the comparator means and responsive to each of the enable signals to select a current path through a selected motor coil; and drive circuit means connected to respond to the enabling means and connected to the motor coils to provide current to the selected coil, the energy stored in the latter being used to reduce the current drawn from the drive circuit means and the circuit providing a controlled average coil current that is dependent on the characteristics of the individual coil. Fig. 2 shows a control circuit 30 for the coils A, B, C of a stepper motor driving a thermal printhead, each coil having an identical enabling and drive circuit 31, 32, 33 controlled by a comparator 38, one input of which receives a logic 1 or 0 signal from terminal 37 and the other input of which receives a triangular waveform signal generated by circuit 40, 41, 42, 43 connected to clock signal input 39. Enabling signals are applied at terminals 34, 35, 36, a typical energization of coil A being as follows:- (1) A logic 1 signal is continuously applied to comparator 38 and an enable signal to terminal 34 whereby, when the comparator input at 43 is less than the logic 1 signal, NAND gate 51 switches on transistors 53, 60, 61 to energize coil A. (2) The coil current produces a feedback voltage across resistor 45, which voltage is added to the triangular signal. (3) When the input at 43 exceeds the logic 1 signal, the comparator output changes to cause gate 51 to switch off transistors 53, 60, 61, whereupon the energy in coil A is discharged through the circuit 45, 58, 59 to prolong the coil current and protect transistor 61. The resistor 59 has counterparts (not shown) for the diodes (58) of the other two coils B and C and has a value such that the coil discharge time is very long with respect to the period of the triangular signal. Hence the coil discharge is not completed when the next coil is selected, thus providing smooth motor start-up. A plurality of coils may be simultaneously energized to produce a braking action.

Abstract: 487,276. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. April 10, 1937, No. 10288. Convention date, Oct. 9, 1936. [Class 27] In a prepayment electricity meter, contacts 12, 13 controlling the supply are adapted to be opened by a slidable actuating member 14 under the action of a spring 17 when a striker arm 24, connected through gearing 22, 21, a ratchet 19 and a spring pawl 20 with the actuating member, is released by a flat on the shaft 23 of the quantity mechanism. Embracing an eccentric 3 secured to the prepayment shaft 1 is an arm 6 fast with a double cam 7, a torsion spring interconnecting the shaft and double cam. Rotation of the shaft 1 through half a revolution after insertion of a coin, tensions the spring, and slowly withdraws the arm 6 from a holding stop 4 by the action of the eccentric 3. When the arm 6 escapes from the stop 4, it flies rapidly round to a second stop 5, and one half of the double cam 7 strikes a roller 18 on the actuating member 14 to displace it out of engagement with the contacts 12, 13 which consequently close. After a slight return movement, the actuating member is again held by arm 24 engaging shaft 23.
