Patent GB-2555147-A (GB)
Title: Operating a network node
Inventor: SALEM AMIN AL-DAMLUJI
IPC: H04L29/06
Filed: 2016-10-12
Abstract: A network node 104 maintains a database of session description protocol (SDP) precondition preferences for downstream network elements 106. On receiving a session initiation protocol (SIP) message comprising SDP preconditions, the network node 104 alters, adds or removes SDP preconditions according to the preferences or capability of the downstream network element 106. To maintain the database, the network node forwards an unmodified SIP message. If an error message or accept message is received from the downstream network element 106, the database is updated with the unsupported or supported preconditions. A second SIP message with modified SDP preconditions is then sent to the downstream node 106. The method reduces the number of error messages and retries leading to lower network traffic.

Title: Down-hole communication across a mud motor
Inventor: HUGH DOUGLAS
IPC: E21B47/18
Filed: 2015-05-19
Abstract: Systems and methods of down-hole communication are disclosed, which facilitate communication across a mud motor. The systems and methods can employ a hysteresis brake that selectively slows a turbine shaft to thereby produce local pressure pules in a drilling fluid in a predetermined pattern. The hysteresis brake can be operated by providing a relatively small control current to produce a relatively large counter torque, which can be transmitted the turbine shaft. The turbine and the hysteresis brake may be provided below a mud motor, and the local pressure pulses may be transmitted to a receiver disposed above the mud motor while the mud motor is operating. The hysteresis brake can be employed when other communication systems fail, and thus can provide a back-up system to permit a drilling operation to be continued.

Title: Superconducting microwave radiation thruster
Inventor: ROGER JOHN SHAWYER
IPC: F03H99/00
Filed: 2016-04-07
Abstract: A superconducting microwave radiation thruster used to accelerate a spacecraft or an airborne vehicle. The thruster includes a flat superconducting surface for the major end plate and a specially shaped, non-superconducting minor end plate and a non- superconducting taper section. This geometry considerably simplifies the manufacturing of the thruster. The thruster includes circularly polarised input and detector antennae which, when combined with a phase locked loop control circuit, enable the input frequency to be corrected for Doppler shifts, caused by acceleration of the thruster. These Doppler shifts would otherwise cause a decrease in cavity Q value, and thus an unacceptable decrease in output thrust.

IPC: H03M1/60
Filed: 2013-06-26
Abstract: A switched capacitor analogue-to-digital converter (ADC) for speech signals is operable in either a low-power input monitoring mode to save standby power, or operable in a high-resolution mode. The ADC comprises an integrator 294 for forming an integrated error signal (analogue filtered signal), a voltage controlled oscillator (VCO) 300, a counter 302 receiving an output of the VCO, and a switch 298 for supplying either a received analogue input signal Sin or the integrated error signal Sfilt to the VCO. The switched capacitor filter components comprise a series input capacitor 402 connected alternately to the input signal via a first switch, or to the integrator input via a second switch, the switches being controlled by opposing phases of a two-phase clock. Additionally, a feedback capacitor array Cfb comprises capacitors 396, 398 connected at one end to virtual earth or to a reference voltage (VRP, VRM) via third switches, and at the other end to the integrator input via the second switch. A decoder block 392 forms feedback control signals based on the output of the counter to control the feedback capacitors, and thus control the feedback component of a signal applied to the integrator input. When the analogue input signal is supplied to the VCO, the feedback path and integrator may be disabled. The input and feedback capacitors may also be merged (fig.18). The A2D converter may form an integrated circuit within a smartphone, camera PDA etc.

Title: Floating facility and method for maturation of alcohol spirits
Inventor: ORRIN HENRY INGRAM
IPC: C12H1/22
Filed: 2017-11-17
Abstract: An alcohol spirit maturation facility such as a barge or another large metal construction storage area is placed on a body of water. Racks may be placed in the storage area and filled with barrels or other containers holding alcohol spirits. The steel construction of the facility draws in and stores solar energy as heat and radiates that heat into the storage area. After the sun sets, the body of water serves as a heat sink to draw away heat. This creates more drastic temperature changes which may benefit the maturation process of stored spirits. Additionally, the natural movements and oscillations of a stationary floating facility as a result of currents, waves, and passing vessels creates a passive churning effect for containers and barrels stored therein. This combination of increased temperature and passive churning may accelerate the maturation process of alcohol spirits.

Title: Floating-point addition
Inventor: DAVID RAYMOND LUTZ
IPC: G06F7/499
Filed: 2020-01-28
Abstract: Floating-point adding circuitry 44 is provided to add first and second floating-point operands each comprising a significand and an exponent. Alignment shift circuitry 50 shifts a smaller-operand significand to align with a larger-operand significand, based on an exponent difference. Incrementing circuitry 52 generates alternative versions of the larger-operand significand, each version based on a different rounding increment applied to the larger-operand significand. A number of candidate sum values are generated by adding circuits 54, each candidate sum value representing a sum of the shifted smaller-operand significand and a respective one of the alternative versions of the larger-operand significand. One of the candidate sum values is selected as a rounded result of adding the first and second floating-point operands. This allows floating-point addition to be performed faster as the latency of the rounding increment can be hidden in the shadow of the latency of the alignment shift.
