Patent number: 7685932Abstract: A system, method and apparatus for increasing the interaction between water and a brewing substance in a brewing apparatus. The structure includes a spray head having a thickness dimension which facilitates the formation and definition of tubes or passages extending therethrough. The passages are directed at an angle so as to provide an extended flow path to and through the brewing substance. The spray head is positioned a dimension above the brewing substance retained in a pod so as to increase the interaction between water dispensed through the spray head and the brewing substance which is infused by the water from the spray head. The use of the angled paths helps to increase the saturation, penetration and agitation of the brewing substance so as to help promote uniformity of extraction of the brewing substance. Additionally, directed flow helps facilitate quicker rate of expansion of the brewing substance within the corresponding chamber thereby helping to improve the overall brewing process.Type: GrantFiled: November 8, 2004Date of Patent: March 30, 2010Assignee: Bunn-O-Matic CorporationInventors: Christopher W.

Patent number: 7261491Abstract: An edger assembly is for a paving vehicle screed for forming a paving material mat upon a base surface. The edger assembly includes a support connectable with the screed and an edger member having a contact surface contactable with the base surface. An actuator has an upper end coupled with the edger member and a lower end coupled with the support, the upper end being displaceable with respect to the lower end to vertically displace the edger member relative to the base surface. The actuator preferably includes two threaded blocks coupled with the support and two rotatable rods each coupled with the edger member and engaged with one block. Rotation of the rods vertically displaces the rods with respect to the support to displace the edger member.

Publication number: 20020061227Abstract: The present invention is directed to a screed assembly that includes a strike-off. This strike-off is directly connected to a screed plate such that the strike-off is able to bend or twist along with movement of the screed plate which occurs during a paving operation. The strike-off in the screed assembly of the present invention is simpler and less costly to manufacture than corresponding devices in existing screed assemblies. Connecting the strike-off directly to the screed establishes a shearing height prior to mounting the screed assembly to the paving machine in set up of the screed assembly faster and easier to accomplish.Type: ApplicationFiled: March 1, 2001Publication date: May 23, 2002Applicant: Blaw-Knox Construction Equipment CorporationInventors: Christopher W.
