Abstract: A coffee roasting machine for roasting coffee, particularly in small batch sizes for sale and distribution to individual customers. The coffee roaster is suitable for placement entirely within a retail sales outlet or establishment and for being operated by any person, such as, an employee, customer, or patron who has little or no knowledge, skill, or experience in roasting coffee beans. The coffee-roasting machine selects an appropriate coffee roasting instruction set, stored internally, that corresponding to information input into the coffee-roasting machine for roasting a particular type of coffee bean or coffee bean blend to a desired roast level. The information is integrally included on a package of coffee beans for roasting and is directly readable by the machine or manually inputtable by an operator.

Abstract: This invention pertains to a siloxane resin composition comprising R1SiO3/2 siloxane units, R2SiO3/2 siloxane units and (R3O)bSiO(4-b)/2 siloxane units wherein R1 is an alkyl group having 1 to 5 carbons, hydrogen, or mixtures thereof; R2 is a monovalent organic group having 6 to 30 carbons; R3 is a branched alkyl group having 3 to 30 carbons, b is from 1 to 3; and the siloxane resin contains from 2.5 to 85 mole percent R1SiO3/2 units, 2.5 to 50 mole percent R2SiO3/2 units and 5 to 95 mole percent (R3O)bSiO(4-b)/2 units. The siloxane resin is useful to make insoluble porous resin and insoluble porous coatings. Heating a substrate coated with the siloxane resin at a sufficient temperature effects removal of the R2 and R3O groups to form an insoluble insoluble porous coating having a porosity of 1 to 60 volume percent and a dielectric constant in the range of 1.5 to 3.0.

Abstract: Silicone resins comprising 5 to 50 mole % of (PhSiO(3-x)/2(OH)x) units and 50 to 95 mole % (HSiO(3-x)/2(OH)x), where Ph is a phenyl group, x has a value of 0, 1 or 2 and wherein the cured silicone resin has a critical surface free energy of 30 dynes/cm or higher. These resins are useful as etch stop layers for organic dielectric materials having a critical surface free energy of 40 dynes/cm or higher.

Abstract: This invention pertains to a siloxane resin composition comprising R1SiO3/2 siloxane units and (R2O)bSiO(4−b)/2 siloxane units wherein R1 is an alkyl group having 1 to 5 carbons; R2 is a branched alkyl group having 3 to 30 carbons, b is from 1 to 3. The siloxane resin contains a molar ratio of R1SiO3/2 units to (R2O)bSiO(4−b)/2 units of 1:99 to 99:1. The siloxane resin is useful to make insoluble porous resins and insoluble porous coatings. Heating a substrate coated with the siloxane resin at a sufficient temperature effects removal of the R2O groups to form an an insoluble porous coating having a a dielectric constant in the range of 2.1 to 3, a porosity in the range of 2 to 40 volume percent and a modulus in the range of 1.9 to 20 GPa.

Abstract: This invention pertains to a siloxane resin composition comprising HSiO3/2 siloxane units, and (R2O)bSiO(4-b)/2 siloxane units wherein R2 is independently selected from the group consisting of branched alkyl groups having 3 to 30 carbon atoms and substituted branched alkyl groups having 3 to 30 carbon atoms, b is from 1 to 3. The siloxane resin contains a molar ratio of HSiO3/2 units to (R2O)bSiO(4-b)/2 units of 0.5:99.5 to 99.5. The siloxane resin is useful to make insoluble porous resins and insoluble porous coatings. Heating a substrate with the siloxane resin at a sufficient temperature effects removal of the R2O groups to form an insoluble porous coating having a porosity in a range of 1 to 40 volume percent and a modulus in the range of 4 to 80 GPa.

Abstract: A water efficient toilet includes a self pressurized tank connected to a water supply through conduits and includes a valve operatively connected to the conduits. The toilet assembly has a bowl with inner walls, the bowl having a lower reservoir connected to a trap way and an upper rim with a channel therein. The channel is provided with a plurality of openings and the lower reservoir of the bowl has through holes. The through holes of the lower reservoir and the channel of the upper rim of the bowl are connected to the valve by a first and second conduit. When flushing the toilet by opening the valve, a phased inflow of water in the toilet is induced. The phased inflow of water includes an initial and an intermediate inflow of water. The initial inflow of water passes into the first conduit and through the through holes of the lower reservoir to initiate the evacuation of the contents of the lower reservoir through the trap way into a drain pipe.

Abstract: A polymer matrix composite comprises a matrix of a cured methylsilsesquioxane resin and a reinforcing material. The composite has low heat release rate, smoke yield, and carbon monoxide yield when burned. After burning, the composite has high char yield and retains much of its initial tensile strength. The method for making the composite comprises applying a silanol-functional methylsilsesquioxane resin comprising 70 to 90 mol % ((CH.sub.3)SiO.sub.3/2) units and 10 to 25 mol % (CH.sub.3 Si(OH)0.sub.2/2) units to a reinforcing material and curing the resin.

Abstract: There is taught a method and apparatus for the removal of foreign material and fluid from a fabric such as a press felt in a paper making machine, wherein a jet of gaseous material is directed at a surface of the felt without penetrating the felt to create a low pressure area to remove the fluid and foreign material within the fabric.
