Abstract: A mixer for mixing food items and ingredients includes beaters removably attachable to the mixer, and the beaters including arms and mixing blades and extending along and wrapping about the arms and mixing blades of each beater is a heating element, preferably electrical wiring or leads, that is embedded in and covered by a heat conductive material such as ceramic, so that the heating element and the heat conductive material can warm up and bring to room temperature the various food items and ingredients for more efficient and quicker food preparation and processing when the beaters are immersed in or submerged within the items or ingredients and the heating element is actuated for producing heat that conducts through the heat conductive material to the food items and ingredients.

Abstract: A knife having a handle component and a blade component, the blade component comprising a pair of opposed flanking side members and a replaceable blade insert confined and held therebetween. The side members are joined together by a blade insert locator and a spacer element at the region of connection to the handle so as to provide a slot forward of the handle for inserting the replaceable blade. The blade insert is configured to engage the blade insert locator and the spacer element so as to be held in the slot completely within the confines of the blade component. A blade insert locking structure is mounted on the blade component so as to be structurally and functionally independent of the handle component. The handle component and blade component may be of either the fixed or folding type and the blade insert may include a gut hook on its terminal end.

Abstract: A knife having a handle section and a blade section, the blade section comprising a pair of opposed flanking side members and a replaceable blade insert confined between the side members and held therebetween. The side members are joined together by a blade insert locator so as to provide a slot for the blade insert. The blade insert is configured to engage with the blade insert locator so as to be held in place in the slot. The blade insert includes a tang configured to extend into the handle section, and the handle section is configured to receive the tang and to confine the tang within the handle section. The handle section includes a tang spacer positioned to separate the side members within the handle section so that the tang fits within the handle section between the side members.

Abstract: Uniformly impregnated liner and medium for making corrugated board are prepared by using a urea-aldehyde impregnating composition to impregnate board in-line and a process where the coated board is treated with an aqueous primer and fully cured to provide board having resin free surfaces.

Abstract: An aqueous starch-based corrugating adhesive containing casein, a carboxylated styrene-butadiene copolymer latex and preferably glyoxal is used to adhere liner and medium substrates having normally abherent surfaces.
