Abstract
A method or system of creating a design for a heat sink comprising receiving: property inputs from a user, including either target physical dimensions for the heat sink including its material of construction, or the maximum temperature of an electrical element adjacent to the heat sink, along with the power level for the electrical element; calculating a predicted temperature of the electrical element; generating comparisons showing the impact of independently changing each of the property inputs and materials of construction and the resulting change to the predicted temperature of the electrical element; allowing the user to change a property input after the comparisons are generated; selecting a design for the heat sink; and creating design specifications to manufacture the heat sink.

Abstract
The invention relates to a method for producing volume reflection holograms with substrate- guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set- up, comprising the steps of (i) providing at least one laser beam source (100) producing a recording beam (101, 102) having a first wave vector (201, 302b, 307), (ii) providing a holographic recording medium (107, 200) on a transparent substrate (106), the substrate (106) having a first flat side facing the at least one laser beam source (100) and an second flat side facing away from the at least one laser beam source (100), wherein the holographic recording medium (107) is arranged on the first flat side or on the second flat side, (iii) providing a reflector arrangement (103, 103') arranged on the second flat side of the substrate (106), wherein the recording beam (101, 102) irradiates the holographic recording medium (107), wherein the recording beam (101, 102) passes through the holographic recording medium (107) and the substrate (106), and is reflected by the reflector arrangement (103, 103') towards the holographic recording medium (107) and the substrate (106) as a reflected beam (104) having a second wave vector (202, 303b, 306), wherein the reflected beam (104) produces an interference pattern with the recording beam in the holographic recording medium (107), the interference pattern having the form of a grating (110, 203) having a grating vector (305), the grating vector (305) being the difference vector of the wave vector (303b, 306) of the reflected beam (104) and the wave vector (302b, 307) of the recording beam (101, 102) and the grating vector (305) also being identical to the difference vector of the wave vector (303a) of a diffracted beam and the wave vector (302a) of a reconstruction beam, and wherein a first plane spanned by the recording beam and the reflected beam is different from a second plane spanned by the reconstruction beam and the diffracted beam and wherein the grating vector (305) of the grating (110, 203) is parallel to 30 the line of intersection of the first and the second plane. The invention further relates to an apparatus for producing volume reflection holograms with substrate-guided reconstruction beams and/or substrate-guided diffracted beams in a single-beam set-up..

Abstract
Devices and methods for dasher board assemblies for sports such as hockey. The dasher board assemblies of various embodiments are configured to reduce impact forces when a user collides with the assembly by increasing the flexibility of the dasher board, which allows for a more gradual deceleration. In some embodiments, the dasher board assembly defines a gap behind the dasher board to allow space for deceleration. In certain embodiments, a foam material is placed between the dasher board and a frame of the assembly. In embodiments, a spline connects adjacent dasher boards without rigid connection to adjacent vertical frame elements. In embodiments, the assembly is configured to provide puck play characteristics that are comparable to conventional dasher board assemblies.

The present disclosure describes a method of manufacturing a one-component coating composition. The method can include combining a water-containing additive with a non-reactive resin to form a grinding dispersion. The method can also include grinding the grinding dispersion to a Hegman value of at least 4 to form a ground dispersion. A drying agent can then be added to form a dried slurry. A silane-modified polyurea can be added to the dried slurry to form a one-component coating composition.

Abstract
Provided is a process for producing a polyisocyanurate comprising: trimerizing an aliphatic polyisocyanate with a trimerization catalyst in the presence of a thermally decomposable acid at a molar ratio of acid to catalyst of from 0.1 to 10, wherein the polyisocyanurate has a greater pot life than the pot life of the polyisocyanurate not containing the thermally decomposable acid. Polyisocyanurates made according to the inventive process lengthen the pot life of pultrusion composite formulations made therefrom without affecting the reactivity of the formulations. The inventive pultrusion composite formulations may be cured and pultruded to yield a variety of products such as wind turbine blades, yacht shells, window frames, door frames, ladder frames, telegraph pole cross arms, tent poles, solar cell frames, solar cell backsheets, radomes, highway guard rails, floor boards, pipes, telegraph poles, auto trunks, luggage holders, engine covers, golf clubs, tennis poles, badminton poles, bicycle frames, surfboards, and snowboards.

Abstract
Processes are described for producing an aromatic diamine-initiated polyether polyol having a measured OH number of 300 to 500 mg KOH/g and a viscosity at 25°C of 5000 to 50,000 mPas. The processes include a first alkoxylation step in which an alkylene oxide consisting essentially of propylene oxide is reacted with a starter consisting essentially of aromatic diamine at a molar ratio of propylene oxide to aromatic diamine of 1.4:1 to 2.0:1 to form an alkoxylated product; and a second alkoxylation step in which an alkylene oxide consisting essentially of propylene oxide is reacted with the alkoxylated product, in the presence of an added catalyst, until the ratio of moles of propylene oxide added in the process to the moles of aromatic diamine added in the process is 4:1 to 9:1.

Suitable phenolic compounds include phenols, phenolic aldehydes, alkylphenols, benzenediols, cashew nut oil, and combinations thereof. Coatings, adhesives, sealants, composites, castings, and films comprising a polyurea composition may be made by reacting a polyisocyanate with the inventive polyaspartic composition. In particular, floor coatings made with the inventive polyaspartic composition have an elongated work time and a short walk-on time compared to current floor coatings.

Abstract
A curable composition, a method of making the curable composition, and an article and product produced therefrom are provided. A morpholinedione is contacted with an isocyanate to form a resin composition. The resin composition is reacted with an amine to form the curable composition. Such curable compositions include adhesives, coatings, castings, sealants, elastomers, and foams. After curing, the morpholinedione-derived compositions exhibit improved performance properties such as microhardness, cross-hatch adhesion, and solvent resistance compared to analogous compositions not made with morpholinedione.
