Title: Process for the preparation of a lubricant base stock comprising the selective thermal decomposition of plastic polyolefin polymer
Inventor: MARTIN PHILIP ATKINS
IPC: C10M105/04
Filed: 2017-03-30
Abstract: A process for the preparation of a lubricant base stock from the thermal decomposition of plastic polymer comprises the steps of: i) introducing plastic polyolefin polymer into a thermal reaction zone of a vacuum pyrolysis reactor; ii) heating the plastic polyolefin polymer at sub-atmospheric pressure, wherein the temperature in the thermal reaction zone of the reactor is from 500 °C to 750 °C, to induce thermal decomposition of the plastic polyolefin polymer and to form a thermal decomposition product effluent which comprises a major portion by weight of a C20 to C60 wax fraction; iii) condensing a vapour component of the thermal decomposition product effluent from the vacuum pyrolysis reactor; and iv) subjecting the C20 to C60 wax fraction of the thermal decomposition product to catalytic hydroisomerization in a hydroisomerization reactor in the presence of hydrogen to form the lubricant base stock; wherein the plastic polyolefin polymer comprises polyethylene and polypropylene in a polyethylene to polypropylene weight ratio of from 60:40 to 90:10. The lubricant base stock may be used in internal combustion engines or turbine bearings.

Title: Improvements in or relating to dynamic channel autocorrelation based on user scheduling
Inventor: Salah Eddine Hajri
IPC: H04L5/00
Filed: 2017-06-30
Abstract: The invention relates to efficient allocation of pilot resources. The autocorrelation over time of terminal channel estimates/motion/Doppler effects are assessed across multiple cells. The terminals are then clustered into groups with similar autocorrelation/motion characteristics, ideally with a maximum of one terminal per cell in each group. The terminals in the groups are assigned the same pilot resources and the number of groups ideally matches the number of different pilot resources available. An optimisation process over a time horizon is done to determine which groups should be assigned pilot resources to update their channel estimate in a given time slot and which should use outdated/stale channel estimate. The optimisation takes into account co-pilot interference/pilot contamination from reuse in neighbouring cells and will tend to update low motion/high autocorrelation groups less often. The claims specify inferring the required pilot throughput of a group from co-pilot interference information.

Title: Synchronization with a host processor
Inventor: DANIEL JOHN PELHAM WILKINSON
IPC: G06F15/173
Filed: 2017-10-20
Abstract: A subsystem for acting as a work accelerator to a host processor 93 comprises an arrangement of tiles with execution units for executing machine code, and an interconnect for communicating between the tiles. The interconnect comprises synchronisation logic to coordinate barrier synchronisations between a group of the tiles, which comprise synchronisation requests being sent to the synchronisation logic, and suspending instruction issue until requests from all tiles in a group are received. The synchronization logic comprises a host sync proxy module 98, comprising a counter 99 written with a number of credits by the host processor, and being configured to automatically decrement the number of credits each time one of the barrier synchronisations requiring host involvement is performed. When the number of credits in the counter is exhausted, the barrier is not released until a further write from the host to the host sync proxy module, but when the number is credits in the counter is not exhausted the barrier is released without a separate write from the host. The synchronisation requests may collectively mark whether host involvement is required. The synchronisation logic may apply a bulk synchronous parallel scheme with alternating compute and exchange phases.

Title: Audio processing apparatus and method of controlling same
Inventor: TAKATOSHI SAEKI
IPC: H03G3/32
Filed: 2017-12-18
Abstract: An audio processing apparatus comprises signal processing means 102, 107 for processing an input audio signal 101. ALC (automatic level control) maintains both a level of recorded audio 112, and an audio signal for monitoring 113 by a user, in an appropriate range. The audio may be monitored by headphones. The signal processing means 102, 107 is configured to increase the gain applied to the input audio signal 101, in a case where the audio signal for monitoring 113 becomes low, in two stages by first increasing a gain applied to the audio signal at first rate 105 and subsequently increasing the gain applied to the audio signal at a second rate 110. The signal processing means may communicate in order to apply recovery or limit gain based on high or low thresholds, and may be used in series (fig.1) or parallel (fig.6) in a video camera. The use of a second signal processing means 107 protects the ears of the listener from excessive volume levels.
