Patent GB-2613542-A (GB)
Title: Heatsink
Inventor: DAVID MORGAN
IPC: H02K9/22
Filed: 2021-11-30
Abstract: A heatsink 100 wrapped around the circumference of the exterior of an electric motor, having direct thermal contact with the stator windings of the motor for removing heat from that motor. The heatsink comprising a curved surface 101 adjacent to the motor, a plurality of cavities 103 formed into the surface, the cavities open on a side of the surface away from the side adjacent to the motor; and a plurality of projections 105, each projection extending from the surface adjacent to a corresponding cavity; wherein each cavity comprises a throat region 107 which is configured to restrict the flow of air between each respective cavity and the region between a corresponding pair of projections. The throat region may have a reduced width. The heatsink may comprise a proximal, central, and distal region. The cavities and projections may be extruded or cast. The cavities may comprise a plurality of parallel channels (113, figure 2) having a partially circular cross-section, the chord of which may form the throat section. The projections may diverge or taper with increasing distance from the surface and may comprise a plurality of cambered aerofoil fins or a plurality of pyramidal structures extending from the surface.

Title: High speed sampling of sensors
Inventor: JULIAN ANDREW JOHN FELLS
IPC: H03H17/02
Filed: 2015-02-05
Abstract: The method involves receiving a set of bursts of samples of an optical signal, where each burst of samples comprises a set of samples of each pulse in a group of discrete optical pulses (A1-E1, A2-E2), groups are regularly spaced in time with a group repetition period larger than group width, and the optical pulses comprise a phase modulated signal. The bursts of samples are processed to obtain a series of regularly spaced samples. The regularly spaced samples are demodulated to retrieve phase information from the detected pulses. The processing step comprises the steps of down-sampling the received samples, up-sampling the down-sampled samples at a rate of the group width multiplied by the sample rate in each burst, then filtering the up-sampled samples and combining the filtered samples. The method increases the effective sampling rate to improve sensor bandwidth and enables locking cycles within a pulse for phase-locked loop to improve locking performance.

Title: A Doppler compensation method using photonic modulation
Inventor: SHYQYRI HAXHA
IPC: G01S13/34
Filed: 2022-02-08
Abstract: This disclosure provides a method of correcting Doppler shift in a received RF signal 23, comprising: receiving, by a photonic device: an optical carrier signal; a received RF signal 23 which has undergone a Doppler shift during a transmission; a corrected local oscillator corrected for the Doppler shift; modulating a first beam of the optical carrier signal with the received RF signal; modulating a second beam of the optical carrier signal with the corrected local oscillator; and, generating, with a photodiode 25, an electrical signal using the modulated first and second beams of the optical carrier signals. The corrected local oscillator is preferably corrected for the doppler shift by inputting to a mixer 41 a reference local oscillator 44 and the received RF signal 23 to provide the difference between the LO and the RF signal, the difference being the corrected local oscillator.

Patent GC-0000158-A (GC)
Title: Process for the co-production of aliphatic diols and cyclic ethers.
Inventor: WILLETT PAUL
IPC: C07B61/00
Filed: 2000-12-13
Granted: 2005-06-29
Abstract: A process is described for the co-production of a diol product (e.g. butane-1,4-diol) and a cyclic ether (e.g. tetrahydrofuran) by hydrogenation of an aliphatic diester or lactone feedstock, such as dimethyl or diethyl maleate, which contains a minor amount of acidic material, such as the corresponding monoester. It utilises a plurality of hydrogenation zones (8, 9, 10) connected in series, each containing a charge (12, 17, 24) of a granular ester hydrogenation catalyst. The first hydrogenation zone (8) contains a bed (12) of a catalyst (e.g. reduced copper chromite) which is tolerant of a minor amount of acidic material, while the second hydrogenation zone (9) contains a bed (17) of a catalyst which provides enhanced yields of cyclic ethers compared to the catalyst of the first hydrogenation zone (8). A third hydrogenation zone (10) contains a bed (24) of a catalyst which exhibits low selectivity towards conversion of the diester to at least one byproduct (e.g. 2-(4'-hydroxybutoxy)-tetrahydrofuran). The feedstock is supplied to the first hydrogenation zone (8) as a vaporous stream comprising hydrogen and the hydrogenatable material and the zones (8, 9, 10) are typically operated under adiabatic conditions. From the third hydrogenation zone (10) there is recovered a final product stream which is substantially free of the hydrogenatable material and which contains the diol, cyclic ether and other byproducts, the selectivity to the cyclic ether being greater in the final product stream than in the first intermediate product stream. <IMAGE>
