Title: Pressure balanced drilling choke
Inventor: TODD ROBERTS
IPC: F16K17/168
Filed: 2018-05-16
Abstract: A drilling choke including a choke body defining an internal region, an inlet passage, and an outlet passage, a seat extending within the outlet passage, a nose extending within the internal region and defining a recessed region, a plug extending within the recessed region, and a stem connected to the plug and extending axially therethrough, the stem defining an internal passage. The plug can be engaged with the seat to at least partially restrict fluid flow from the inlet passage to the outlet passage via the internal region. The stem and the plug are together axially moveable in opposing directions relative to the seat to thereby control a backpressure of the fluid flow. In some embodiments, the recessed region of the nose is in fluid communication with the outlet passage of the choke body via the internal passage of the stem to thereby pressure balance the plug.

Title: Blockchain blocks & proof-of-existence
Inventor: JACK OWEN DAVIES
IPC: G06F16/21
Filed: 2021-07-14
Abstract: A computer-implemented method of constructing a candidate block of a blockchain comprises obtaining a set of blockchain transactions, obtaining a transaction representation by inputting each of the transactions to a Bloom filter that utilises one or more hash functions, and including the transaction representation in the candidate block, such as in the block header. This may avoid the need to calculate a Merkle root for the block. A method of determining whether such a block contains a particular target transaction comprises obtaining the target transaction and inputting it to each of the hash functions utilised by the Bloom filter. The result of this is then compared to the transaction representation of the block in the standard way that a Bloom filter is used to test for membership of a set.

Title: Ejection seat parachute deployment systems and methods
Inventor: KASSIDY L CARSON
IPC: B64D17/62
Filed: 2023-01-30
Abstract: An aircraft ejection seat controller (fig.3,302) has a computer-readable storage containing instructions causing a processor to determine a speed and an altitude, and command simultaneous deployment, within 150ms of one another, of a drogue parachute 210 and a main parachute 220 upon separation of the ejection seat 14 from the aircraft (fig.1,12). The speed may be that of the aircraft or the ejector seat. The processor may determine that the aircraft or ejection seat are within a zone having a speed range between 13-154ms-1, and altitude range up to 6096m, which may be based on data from two dynamic pressure sensors (fig.3,306,308). The drogue parachute may be deployed prior to the main parachute, a delayed separation or severing of the drogue after 100-400ms may be commanded, and then the main parachute deployed. If the speed is below the zone’s threshold and altitude is less than the zone’s maximum, then only the main parachute may be deployed. There may be a threshold speed within the zone that decreases or stays the same as altitude increases.
