Patent GB-2589786-A (GB)
Title: Through-air drying apparatus and methods of manufacture
Inventor: Daniel Keith Lawson
IPC: F26B21/10
Filed: 2018-06-27
Abstract: Methods of improving the drying rate of a cellulosic web, such as a tissue web, by providing an apparatus having two noncompressive dewatering devices, such as two through-air driers, where the temperature of the drying medium supplied to each device is separately controlled. The temperature of the medium supplied to the first device may exceed 450°F, such as from about 450 to about 600°F. On the other hand the temperature of the medium supplied to the second device may be less than the temperature supplied to the first, such as from about 350 to 450°F. Drying the web in this manner not only improves drying efficiency, but also limits or prevents degradation of the web, such as the combustion of cellulosic fibers making up the web or monosaccharides associated therewith. As such, webs that are substantially free from furan and acetaldehyde may be produced by the present methods.

Patent GB-2596393-A (GB)
Title: High-speed computer generated holography using convolutional neural networks
Inventor: NICOLAS CHRISTIAN RICHARD PÉGARD
IPC: G06N3/02
Filed: 2021-04-20
Abstract: A method for computer-generated holography comprises providing a target holographic image illumination distribution AT to a trained convolutional neural network (CNN). Using the CNN, a predicted complex optical field P0 is generated in an image plane downstream from a spatial light modulator (SLM). The complex optical field is back-propagated (using an inverse Fourier Transform iFT) to a SLM plane to produce a predicted SLM phase mask φSLM. The SLM is configured according to the predicted SLM phase mask and incident coherent light is passed therethrough in order to produce a holographic image at the image plane. The method avoids the need for iterative methods for computer-generated hologram generation which enables faster hologram generation. An method for training the associated convolutional neural network (CNN) is also disclosed in which the predicted SLM phase mask is evaluated using a cost function based upon a comparison between the reconstructed target image distribution AR and the original target image distribution AT. Cost function values are fed back to the CNN which adjusts its parameters to achieve desired cost function values.

Title: Aerodynamic control surface
Inventor: DAREN HEALY
IPC: B64C13/28
Filed: 2021-11-26
Abstract: An aerodynamic control surface assembly includes a structure 2 with an aerodynamic surface 8 and a curved aerodynamic control surface 20 configured to move between extended 240 and a retracted 22 position. An actuation mechanism 252a moves the control surface between positions. The control surface deploys through an aperture 18 (fig.4A) in the aerodynamic surface and into an oncoming airflow in the extended position. The actuation mechanism is configured such that the control surface follows a curved kinematic path 40 (fig.4A) as the control surface moves between positions. The actuation mechanism remains fully behind the aerodynamic surface throughout the movement of the control surface between said positions. The actuation mechanism may comprise a four-bar linkage. The control surface may be non-linear in a direction transverse to oncoming airflow e.g., corrugated. The profile of the control surface may be a blade, with curvature matching a path of variable curvature of the actuation mechanism allowing the aperture in the aerodynamic surface to be substantially the same as the blades maximum thickness. The control surface may be configured as a lift dump spoiler. Also disclosed is an aircraft assembly, and method of controlling an airflow, using a curved aerodynamic control surface as described.

Title: Apparatus for free-flowing material and corresponding methods
Inventor: TREVOR LEONARD POOLE
IPC: B65G43/00
Filed: 2022-03-30
Abstract: A conveyor assembly 1 comprising a lid portion 10 for at least partially covering a container 200. The lid portion 10 comprises at least one inlet 11 for receiving free-flowing material 200, such as biochar or ash, over a first predetermined period of time. The conveyor assembly 1 also comprises an engagement portion 12 for engaging the lid portion 10 to the container 200, and a conveyor 14. The conveyor is operable to distribute free-flowing material 100 within the container 200, and may be in the form of an auger, which has been dispensed into the container 200 from the at least one inlet, when the lid portion 10 is engaged to the container 200 using the engagement portion 12about at least one sensor. This allows conveyor assembly 1 to better ensure that container 200 is suitably filled with free- flowing material 100 over a relatively long period of time, autonomously, to allow filled container 200 to be transported elsewhere using a transportation vehicle 400 once container 200 is sufficiently filled with free-flowing material 100.

Abstract: This structure consists of a double sack made of nylon, odourless, tasteless and light, used for cleanness of diary ruminants. It comprises of two sacks (one inside the other) each one forming a cavity at the side, thus creating bags on the internal edges of each sack (Pic. 1). The exterior sack has two handholds whereas the interior one (which is more of an angular edge of a sack) having no handholds, bears holes at its bottom and a slit on the upper side thereof - on the fold between the interior and exterior sack; it is adjusted, watertight, at approximately the middle of the exterior sack like a pyramidal diaphragm with its base being open upwards (Pic. 2). An inclined plane is adjusted above the diaphragm while a sponge is placed thereunder (Pic. 2,4). The double sack is attached on three sides thereof to the hairs of the area around animal's genital organs near its tail in a way that is comfortable for the ruminant. Excrements of the animal fall inside the sack and are separated by virtue of the perforated plane from which urine pass through the holes of said pyramidal diaphragm and are absorbed by aforementioned sponge (Pic. 3,4,5,6,7,8).

Abstract: A thumb-sized tape cassette having a rectangular housing with top, bottom, front, back and side walls. The front wall is provided with a center opening and side openings disposed on opposite sides of the center opening. A tape member, which runs between supply and take-up reels within the cassette, is guided in a run behind the front wall and is accessible through the front wall openings. A pressure-pad spring is supported on a post within the housing, this spring being formed as an integral continuous-surfaced leaf spring having only two bends therein to define a central section between the two bends and a leg extending from each of the respective bends. A pressure pad is secured to each leg; and the central section is supported on the support post. A pair of fulcrum posts is provided within the housing on either side of the support post to contact a surface of the leaf spring and provide a respective fulcrum for each leg.
