Patent GB-2617341-A (GB)
Title: An ancillary water heating system
Inventor: TOBY CHAMBERLAIN
IPC: F24D17/00
Filed: 2022-04-04
Abstract: An ancillary water heating system comprises a supplemental heater 30 (e.g. one or more electric heating elements) configured to heat water flowing within a pipe 20 that, in use, transfers water heated by a primary heater 10 (e.g. boiler, heat pump) to a water outlet 50 (e.g. tap). A controller 70 transmits command signals to the supplemental heater based on signals received from a sensor 40 disposed on/in the pipe. In a first aspect, the sensor is a temperature sensor 40A monitoring the temperature of the pipe or water therein, and the controller activates the heater when the detected temperature is below a predetermined value. Conversely, the controller deactivates the heater when the detected temperature is above the value. In a second aspect, the sensor is a flow sensor 40B monitoring water flow within the pipe. When water flow is detected, the controller activates the heater. The heater is deactivated when the sensor determines that a predetermined volume of water has flowed through the pipe (e.g. the volume between the primary heater and the outlet). The two aspects ensure instantaneous hot water at the outlet even when water heated by the primary heater has cooled in the pipe.

Title: Vacuum component and vacuum apparatus
Inventor: PAUL DAVID SMITH
IPC: H05B3/42
Filed: 2022-06-01
Abstract: A vacuum component for a vacuum apparatus, such as a tube 10, comprises a wall element 12 having an outer surface 14 outside the vacuum and an inner surface 16 inside the vacuum, a layer heating element 20, such as a metallic or ceramic resistive heater, connected to the outer surface, and a non-evaporable getter (NEG) material layer 26 connected to the inner surface at a position corresponding to the position of the heating element. The NEG material layer may comprise a dense NEG material layer 28 and a columnar NEG material layer 30, which layers may cover the complete inner surface of the component. Thermal insulation may be included to provide a thermal barrier to prevent heat from the heating element spreading to other components of the vacuum apparatus.

Title: A method and system for carbon sequestration
Inventor: PATRICIA ESTRIDGE
IPC: B01D53/84
Filed: 2022-03-31
Abstract: A system and method are provided for sequestering carbon. The system comprises apparatus for sinking plant material, such as seaweed in batches, each batch containing a known amount of plant material. The sinking of a batch of plant material represents a carbon sequestration event. The system further includes an apparatus for imaging the sinking of a batch of plant material to confirm a carbon sequestration event and an apparatus for determining the time and location of the carbon sequestration event. The system further includes a computer system for creating and storing a verification data record for the carbon sequestration event. The verification data record includes the imaging of the carbon sequestration event, the timing and location of the carbon sequestration event, and the known amount of plant material that was sunk for the carbon sequestration event. The system further comprises apparatus for determining the depth underwater at which a batch of plant material is released for sinking, and wherein the determined depth is included in the verification data record. Advantageously carbon is stored at the bottom of the sea rather than on land and is therefore a relatively irreversible sequestration.

Abstract: This invention relates to coated abrasive products having a resinous binder which holds and supports abrasive granules on a backing sheet. 
<??>In the manufacture of coated abrasives, the make coat resinous binder and abrasive granules are first applied to the backing, then the size coat resinous binder is applied, and finally, the construction is fully cured. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g. heat resistance. 
<??>With polyester or cellulose backings, however, curing temperatures are limited to about 130 DEG  C. At this temperature, cure times are long. The long cure times necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include formation of defects at the suspension rods, inconsistent cure on account of temperature variations in the large festoon ovens, sagging of the binder, and shifting of abrasive granules. Furthermore festoon curing areas require large amounts of space and large amounts of energy. 
<??>This invention provides a coated abrasive product comprising abrasive granules adherently bonded to at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the binder material can be used in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
