The present invention relates to a process for making a bread product. The process includes the addition of a non-maltogenic exoamylase that hydrolyses starch to a starch medium, and the application of heat to the starch medium. The non-maltogenic exomylase cleaves one or more linear malto-oligosaccharides, predominantly consisting of from four to eight D-glucopyranosyl units, from non-reducing ends of amylopectin side chains. The non-maltogenic exoamylase has an endoamylase activity of less than 0.5 endoamylase units (EAU) per unit of exoamylase activity.

A method of manufacturing a cementitious composite including: (1) mixing an extrudable cementitious composition by first forming a fibrous mixture comprising fibers, water and a rheology modifying agent and then adding hydraulic cement; (2) extruding the extrudable cementitious composition into a green extrudate, wherein the green extrudate is characterized by being form-stable and retaining substantially a predefined cross-sectional shape; (3) removing a portion of the water by evaporation to reduce density and increase porosity; and (4) heating the green extrudate at a temperature from greater than 65° C. to less than 99° C. is disclosed. Such a process yields a cementitious composite that is suitable for use as a wood substitute. Particularly, by using higher curing temperatures for preparing the cementitious building products, the building products have a lower bulk density and a higher flexural strength as compared to conventional products. The wood-like building products can be sawed, nailed and screwed like ordinary wood.

The present invention more specifically discloses a thermoplastic elastomer composition that is made by a process comprising: (1) mixing (A) a block copolymer comprising a first polymeric block that is comprised of repeat units that are derived from a vinyl aromatic monomer and a second block that is comprised of repeat units that are derived from a conjugated diolefin monomer, wherein the repeat units in the second block are hydrogenated, and wherein the repeat units in the second block are elastomeric in nature, (B) a crosslinkable elastomer, and (C) an oil, to produce an un-crosslinked three component blend; and (2) dynamically crosslinking the crosslinkable elastomer in the un-crosslinked three component blend during a thermo-mechanical mixing step; wherein the thermoplastic elastomer composition is void of thermoplastic resins.

A rotary tool (T) has a rotary segment (10) with an opposed surface opposed to a work surface and a plurality of cutting parts (20) arranged on the opposed surface. Some cutting parts (20) include tips (22a) made of a grinding tool segment obtained by binding abrasive grains by a metal binder and the other cutting parts (20) include tips (24a) made of a sintered material harder than the grinding tool segment, and the respective cutting parts (20) are arranged such that the tips (24a) are located at positions more outward than the tips (22a) with respect to radial directions of the rotary segment.

A pressure control and feedback system for an adjustable foam support includes a vacuum pump for drawing air from a hermetically sealed foam core to reduce the firmness of the core. A valve opens to permit and closes to block the passage of air into and out of the core. A remotely operated controller generates control signals to selectively start and stop operation of the pump, and selectively open and close the valve, which provides a selected level of pneumatic pressure and corresponding firmness in the core. A pressure sensor detects the pressure and firmness of the core and generates representative feedback signals. An indicator device responsive to the feedback signals indicates the sensed firmness of the core. Software calibrates the system and provides the system with intelligent operation.

A foldable display device includes: a display panel having a folded portion bendable along a fold line; and a cover window disposed on the display panel, wherein the cover window includes: at least a soft pattern disposed on the folded portion of the display panel; and a hard coating layer disposed on the display panel having the soft pattern formed thereon, and the soft pattern has a triangular cross section.

An anti-snore neck-support pillow includes a molded foam body and a fabric covering. The body includes front, back and middle portions. The back portion is thinner than the front portion and thicker than the middle portion. The top surface of the body has a concave curve between the front and back portions. The molded foam conforms around a support member disposed within the front portion. Vertical holes pass completely through the middle portion. The body has a flat bottom surface with an indentation located opposite the concave curve of the top surface. The support member increases the firmness of the foam in the front portion, whereas the holes and the indentation decrease the firmness of the body in the middle portion. The user's head is tilted back when the support member lifts the user's neck, and the holes and indentation allow the user's head to sink into the middle portion.
