Title: Synthesis of cyanurate and multifunctional alcohol-based polyether acrylate for uv curable materials
Inventor: YUAN ZHONGSHUN
IPC: C09D11/101
Filed: 2020-10-30
Abstract: Polyether (meth)acrylates based on cyanuric acid or substituted cyanuric acid and multifunctional alcohol, which optionally include triethanolamine units, have wide applications in UV curable adhesives, coatings, inks, sealants, paints or 3D printing. These polyether acrylates have rigid cyanurate structure endowing the material with extra strength and thermal stability. Furthermore, triethanolamine unit, when present, endows the material with anti-oxygen inhibition property in UV  curing process. These polyether (meth)acrylates have low viscosity and high reactivity towards UV curing. The cured resins have high resilience and strength.  The process of making the polyether (meth)acrylates includes the synthesis of trifunctional polyether polyols through controlled polymerization of propylene oxide using multifunctional alcohol (such as glycerol and sucrose), cyanuric acid acid or substituted cyanuric acid, and optionally triethanolamine, in the presence of a catalyst, followed by the synthesis of polyether (meth)acrylates through transesterification or through direct esterification of the trifunctional polyether polyols.

Title: Pocketed spring unit and method of manufacture
Inventor: SPINKS SIMON
IPC: A47C27/06
Filed: 2019-12-20
Abstract: A pocketed spring unit comprising an array of springs (120) located in pockets (180) formed by discrete superposed webs (140) of pocketing material joined together by welds W between the springs, wherein the welds are located at alternately opposite ends of the pocketed springs. Figure (1) shows generally a pocketed spring unit at a first stage of manufacture. A row of coil springs (120) (only the end one of which is visible) is introduced by an inserter mechanism (130) into position between axially disposed webs (40a and 140b) of pocketing material. The webs (140a and 140b) are fed from supply reels (not shown via guide rollers (150). The springs (120) are partly compressed and are pushed between plates (160) towards the webs (140) by the inserter (130) in the direction of Arrow A1. Once the springs are between the webs (140) a pair of ultrasonic welding tools (170a and 170b) joins the webs together at weld locations W between the springs to form individual pockets (180) for the springs. One of the tools is a sonotrode/horn and the other is a base/anvil. Successive rows of springs are encapsulated by welds W that alternate between the axial ends of the springs, so that one is at an upper axial end and the next is at a lower axial end. The webs (140) may also be welded together along their edges (not shown) i.e. at the ends of the rows and between adjacent springs in the same row, to fully form the pockets.

Abstract: Among other things, two or more different antibodies are caused to bind to one or more units of a chemical component in a sample. Each of the antibodies is attached to one or more beads (e.g., microbeads). The sample is situated on a surface of an image sensor. At the image sensor, light is received originating at a light source that is other than the beads. The received light includes light reflected by, refracted by, or transmitted through the beads. The image sensor captures one or more images of the sample including the beads. At least one of the images of the sample is processed to separately enumerate individual beads and complexes of two or more of the beads attached to the two or more antibodies that are bound to a unit of the chemical component. The results of the processing are used to identify a presence or a level of the chemical component in the sample.
