Patent GB-2592626-A (GB)
Title: Method of generating a public key
Inventor: CRAIG STEVEN WRIGHT
IPC: H04L9/32
Filed: 2020-03-04
Abstract: A second public key is generated based on a first public key using blockchain transactions. A first party generates an output script (locking script) of a first blockchain transaction, the output script comprising a public key derivation script configured to, when executed alongside an input script (unlocking script) of a second blockchain transaction, generate the second public key based on the first public key. The input script of the second blockchain transaction comprises the first public key. The first blockchain transaction is transmitted to node(s) of a blockchain network for inclusion in the blockchain. The public key derivation script may comprise a hashing script which may be a hash-based message authentication code (HMAC) script. The first and second public keys may be in respective levels within a hierarchy of public keys. Deriving public keys on chain has the benefit that a party can prove the link between two public keys and is useful in the context of public key infrastructure (PKI), where a single public key is certified and then related public keys certified by extension. Privacy is also increased since the generated public key can be used to sign transactions but never explicitly stored on chain.

Title: Balancing of heating systems
Inventor: Petr Fadmy
IPC: F24D19/10
Filed: 2020-09-23
Abstract: A heating system 100 comprises a plurality of radiators 112,122,132 and a boiler 150 (e.g. condensing boiler). Each radiator has a respective outlet valve 116,126,136 connected to an outlet of the radiator whereby each outlet valve is configured to respond to the temperature of fluid (e.g. water temperature) at the outlet to control fluid flow rate through the outlet to bring the fluid temperature at the outlet to a target temperature. All the radiators have a mutual outlet temperature so the system is balanced to enable a common boiler return temperature. The outlet valve ideally comprises thermally responsive wax (117, figure 3) that urges a piston (118, figure 3) to reduce water flow at higher outlet water temperatures. Each outlet valve is ideally calibrated prior to connection so the target temperature is 10 to 16 degrees lower than the temperature of water leaving a condensing boiler so that the return water temperature is below the condensation temperature of the boiler, thereby ensuring boiler efficiency. Each radiator may also include a thermostatic radiator valve 114,124,134 on its inlet to control heating of a room 111,121,131 in which the radiator is located. A method and kit of parts are also claimed.

Title: Reduction of water/energy waste in a water provision system
Inventor: Peter Konowalczyk
IPC: F24D19/10
Filed: 2021-08-02
Abstract: A hot water system 100 includes a water heating device providing heated water to an outlet (e.g. tap). A control unit 110 in communication with the heating device sets a timer to begin counting when the outlet has been opened, and initiates a warning if an elapsed time of the timer passes a first threshold value, e.g. 20 seconds. Ideally, if the elapsed time passes a second threshold value higher than the first, e.g. 40 seconds, the control unit closes the water outlet, i.e. stops the flow of hot water supplied to the tap. The first and second threshold values may be set by an artificial intelligence algorithm based on historical usage of the system or manually set by a user. Ideally the water heating device is a thermal energy store 150 containing a phase change material (PCM, e.g. paraffin wax) heated by a heat pump 140, with water being heated by thermal exchange with the PCM.
