The present invention is a bakery product produced by compressing stacked sheets of dough into a laminate and baking the laminate. The bakery product includes a first sheet of dough and a second sheet of dough. The first sheet of dough has a first grain direction. The second sheet of dough has a second grain direction. The second sheet of dough is positioned in facing engagement on the first sheet of dough to form a laminate of dough, wherein the first and second grain directions are positioned generally not parallel with respect to each other. The present invention is also directed to the apparatus and method used for producing the above-described bakery product.
摘要:
A flow control valve for medical liquid is disclosed. The valve has a housing including an inlet, an outlet, and a flow path therebetween. A plurality of flow restrictors are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member is rotationally movable and defines an annular gap and radial groove which provide fluid communication between the different planes and the outlet regardless of the orientation of the flow control member. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.

A medical infusion pump (10) using a pump chamber cassette (86) has a housing (20,22) defining a pump chamber cassette receptacle (84) and a pump driving mechanism (250) for propelling liquid through the pump chamber cassette. A door (50) holds the pump chamber cassette (86) within the cassette receptacle (84) in an operative position relative to the driving mechanism (250). The cassette includes an elastomeric conduit (132), a frame (134) and clips (146,148) for attaching the elastomeric conduit (132) to the frame (134) for holding the elastomeric conduit (132) in a select position relative to the pump driving mechanism (250) of the infusion pump upon placement of the cassette (86) in an operative position relative to the pump driving mechanism (250). An anti-free flow device (136,138) includes the flexible conduit (132) received between an anvil (182) fixedly attached to the frame (134) and a pincher (132) attached to the frame (134), the pincher (138) being movable between a first position biasing the pincher (138) against the anvil (182) to occlude a lumen (150) of the elastomeric conduit (132) and a second position for eliminating the bias of the pincher (138) against the anvil (182) so as to not occlude the lumen (150) of the elastomeric conduit (132). The elastomeric conduit (132) is made of an elongate elastomeric robe having an inlet valve portion (142) and an outlet valve portion (144) made of a furst material and a chamber portion (140) disposed therebetween, the chamber portion being made of a second material. The first material has a durometer of less than a durometer of the second material. The chamber portion (140), inlet valve portion (142) and the outlet valve portion (144) may have a football-shaped cross-section.
