Abstract: An automatic beverage brewing apparatus which includes: a brew chamber assembly; a piston assembly projecting through the brew chamber assembly; a drive apparatus attached to the piston assembly for moving the piston assembly through the brew chamber; and a water distribution system for distributing brew water and flush water to the brew chamber assembly. The piston assembly can be controllably axially displaced and rotated. The piston assembly includes: a generally elongated spool member and an elongated shank portion connected to the spool member; a central axis extending coaxially through both the spool member and the shank portion; a flush water bore extending through the spool member and the shank portion generally coaxial with the central axis. A throat is formed through a top end of the brew chamber and a drain hole formed in a bottom end of the brew chamber.

Abstract: An adjustable measuring apparatus for repeatably measuring a selected volume. The adjustable measuring apparatus includes a hollow sleeve having two sleeve apertures formed through opposed spaced apart surfaces of said sleeve. A first sleeve aperture formed on a top side of the sleeve is formed for receiving material therethrough. A second sleeve aperture formed on a bottom surface of the sleeve is formed for dispensing material therethrough. A cylinder is rotatably retained in the sleeve and has a cylinder aperture formed therethrough for selectively communicating with the first and second sleeve apertures. A piston is adjustably retained in the cylinder for adjustably controlling a volume of the cylinder. An adjustment member is provided and attached to the piston for adjustably positioning said piston in the cylinder.

Abstract: The adjustable measuring device of the present invention has a housing containing an arcuate chamber guide having movable plates attached to it so as to define a metering chamber of variable size. The housing has a housing inlet at the top, communicating with a chamber inlet, and a housing outlet at the bottom, communicating with the metering chamber. An amount, predetermined by the size of the metering chamber, of material to be ground leaves a hopper, and enters the metering chamber through the housing inlet and the chamber inlet. The housing is slid, thereby closing the hopper, until the housing outlet is positioned over a grinding area. Then, the material is discharged into the grinding area to be ground.

Abstract: Disclosed is a multiprocessor computer system including a plurality of processor modules with each of the processor modules including at least one processor and a cache memory which is shared by all of the processors of each processor module. The processor modules are connected to a system bus which comprises independent data, address, vectored interrupt, and control buses. A system memory which is shared by all the processor modules is also connected to the buses, and the cache memories in each processor module store those memory locations in the main memory most frequently accessed by the processors in its module. A system control module controls the operation and interaction of all of the modules and contains the bus arbiters for the vector, data and address buses. The system control module also controls the retrying of requests which are not completed and should any requester fail to obtain access to a bus, the system control module also unjams this deadlock.

Abstract: A coffee grinder discharge chute for use with a coffee grinder operatively attached to a discharge opening in the grinder. The chute is comprised of a generally vertical elongate channel-shaped body having a generally tubular upper section and a channel-shaped lower portion. A grind directing cover is hingedly attached to the chute body over the channel-shaped lower portion to adjustably enclose the flow of ground coffee discharged through the chute thereby shielding the discharged ground coffee from ambient air currents. An end of the chute has sides which are cut back to provide increased grind flow therethrough and an inwardly directed end portion against which the coffee exerts a force to open the hingedly attached cover member. A chaff suppressing grinder discharge cleaning baffle is attached generally in the upper portion of the chute body. The baffle includes a plate member to which is attached a plunger and a clean-out lever.

Abstract: This specification discloses a microwave antenna system using an offset J-hook feed to achieve low sidelobe energy level over the entire radiation space from an electrical circular reflector antenna. An electromagnetic horn is positioned along the central axis of symmetry of a parabolic reflector. A waveguide feed is coupled to the horn and intersects the reflective surface at a position offset from the axis of symmetry.
