Abstract: An axial flow combine harvester having a combination impeller and rotor. The rotor has a front end and is rotatable in a specified rotational direction during normal operation of the combine harvester. The impeller comprises a front, a rear, a mount for fitting the impeller on the rotor with the rear of the impeller adjacent to the front end of the rotor, and a pair of impeller blades extending radially outwards from the mount. The impeller blades are hook-shaped when viewed from the front end of the impeller with outer ends projecting in the rotational direction of the rotor.

Abstract: A data storage subsystem which reduces seek time, by defining a logical storage space wherein part of the logical storage space is defined to correspond to a primary storage space of a first physical data storage device, and correspond to a secondary storage space of a second physical data storage device, and another part of the logical storage space is defined to correspond to a primary storage space of the second physical data storage device, and correspond to a secondary storage space of the first physical data storage device. For hard disk drives having an arm assembly with a read/write head, the average seek distance for both drives reduced, since the pivoting arm assembly need not travel as far to reach each physical storage address within a primary storage area. The invention may additionally take advantage of geometric or other aspects of the storage devices which result in some portion of the device having a faster access time that another portion.

Abstract: A trace facility for a computer system attachment network, a method for operating that network, and trace tools in the network. The network has a plurality of the trace tools, each connected to a communication path, the trace facility providing a system wide trace. The trace facility comprises at least one trace buffer at each trace tool. Each trace tool has an address filter selecting an address range of information on the bus, the information being communicated on the bus as events, and storing the selected event information in the trace buffers, thereby conducting a trace. A breakpoint connection is provided interconnecting each of the trace tools. A trace tool control at each trace tool responds to a trace stop command addressed to the trace tool, to stop the trace at its address filter and trace buffer, and to issue a breakpoint signal on the breakpoint connection to all the interconnected trace tools.

Abstract: A feed enclosure for birds and small creatures such as squirrels, raccoons or the like. A internal floor to ceiling enclosure partition prevents feeders from one side of the enclosure from entering into the feeding area entered from the other side. Small birds may enter from one side of the enclosure while larger birds and small creatures can feed from the other side. The larger birds may feed through an elevated opening by stretching their necks over a lower apron while the small creatures can enter into one of the two enclosed areas by one or more lower openings. Smaller birds enter the enclosure's other side through smaller spaced vertical partitions located over a lower wire mesh fence through which the small creatures are prevented from entering.

Abstract: Disclosed is an apparatus for increasing the effectiveness of hammer-type pile drivers by making possible the use of higher hammer velocities without damaging the pile or the equipment. The apparatus includes a pair of aligned cylinders of unequal diameter, the smaller of which contains an anvil piston and the larger of which contains a driving piston, connected to a pile cap engageable with a pile. Means are provided for applying a deadweight load to the apparatus and for maintaining the space lying between the pistons full of liquid. In addition to enabling use of higher hammer velocities, the apparatus effectively incorporates the deadweight load into driving force when the hammer strikes.

Abstract: Disclosed is a high pressure intensifier for liquids which includes a housing having a pair of interconnected intensifying chambers with a pair of orifice effect valves, one located in each chamber, but carried on a single stem. The valves are arranged to alternately block the flow of liquid from each chamber to a low pressure exhaust port. Each intensifying chamber is provided with a high pressure exhaust port having a check valve therein. Liquid is fed to each chamber through ram tubes arranged in a trombone configuration. When flow from one intensifying chamber to the low pressure exhaust is blocked, the inertia of the decelerating liquid in the ram tube for that chamber forces a stream of high pressure liquid out through the high pressure exhaust port for that chamber.

Abstract: An electroacoustic transducer in accordance with the present invention comprises a perforated backplate having a plurality of upstanding parallel ribs between which conductive surfaces are situated. The conductive surfaces are electrically interconnected with one another and with a contact surface on a relieved shoulder at one end of the backplate.
