Trapping and/or processing of read/write accesses to hardware devices represented to the host through a memory mapped space may be performed without knowledge of the processor's instruction set or semantics of the processor's instructions. A single step routine may be executed to recognize page faults occurring from read/write accesses to emulated memory pages and causing the guest to retry the operation on a single step buffer. The hypervisor may perform post-operation processing on the single step buffer after the guest retries and completes the read or write access. For example, on a read request, the single step routine may place the guest value in the single step buffer for reading by the guest on a retry operation. On a write request, the single step routine may direct the guest to retry the write operation into the single step buffer. After the retry operation the single step routine may read the guest value from the single step buffer and place the guest value in a register of an appropriate emulated system.

A device is described for capturing certain predetermined types of mail pieces from a moving mail flow and for regulating the subsequent delivery thereof to processing equipment. The device is comprised of a receiving station and a delivery station linked by a common narrow transport. The latter forms a shallow shelf or ledge situated at the bottom of the receiving station and adapted at any given time to catch a limited number of certain types of mail from a mixed stream as it flows through the station. Additionally, the receiving station includes a vane-like member for selectively deflecting all of the mail from the transport. The operation of the member is under control of the delivery station and depends upon whether or not mail pieces awaiting further processing downstream are present in the station. The motion of the transport is controlled by both the delivery station and the processing equipment to insure that they will be kept continuously supplied with mail.

A punch press (20), for punching a workpiece, utilizing an elongated punch support which is formed from removable interconnected punch cartridges (92) and an elongated die support which is formed from removable interconnected die cartridges (94). A punch head (32) is supported from a frame (30) which spans the punching area. A two axis positioning system is provided for positioning the sheet metal workpiece within the punching area beneath the punch head. Punch head (32) through appropriate mechanical interposer (160) engages a punch which in conjunction with an associated die, positioned there beneath, forms a hole in the workpiece. The elongated punch sections (92) and die sections (94) can be moved out of the punch press frame, disengaged and removed or replaced. The first punch section (92) and first die section (94) engage driver sections (192, 194) which are disposed in the frame (30). The driver sections (192, 194) are then moved to bring the tool supporting sections (92, 94) into the press.

A document singulator is described for use in separating into single items mail pieces derived from a source of collection mail. The device comprises a plurality of spaced-apart singulation stations each having a friction roller and adapted to be actuated in a predetermined manner to effect the separation of documents lying on top of one another. The rollers are mounted in an inclined slide which has a compound slope and a single registration wall, thereby assuring mail flow down the length of the slide as well as proper registration of the mail pieces at each station. The device is capable of processing a variety of mail pieces including flats such as magazines, folded newspapers, etc. , and is virtually free from hard, mail-damaging jams.

This invention relates to a coupling system for connecting one or more fluid conduits wherein the system is adapted for lateral entry of one pipe or conduit to the other. The coupling system is also suited for making a connection in an environment which is relatively inaccessible to personnel and may be remotely operated.

A punch press (20) having a worktable (40) for supporting a worksheet (21), a two axis positioning mechanism for positioning the worksheet under a punching head (34) and universal grippers (44, 46) supported on the worksheet positioning mechanism which can grip either the end or sides of a worksheet (21). The two axis positioning mechanism is formed from a carriage (42) which is movable along the worktable (40) and a cross slide (41) which is mounted from and movable across the carriage (42) to provide the two axis sheet positioning. The grippers (44, 46) are mounted from a T-slot (130) formed in the cross slide (41) and can be moved to different positions to accommodate various sheet sizes. Aligning pins (140, 142, 143, 144) which can be used for aligning worksheets are provided. Aligning pins (140, 142, 143, 144) during operation are retracted beneath the worktable (40).

A method for controlling punch press noise in which the noise level produced is monitored by a detector and the press ram velocity is modified in real time to keep the noise level within preset limits. A time weighted average noise level is also controlled by varying the ram velocity for punching operations over a period of operation to maintain a projected time weighted average within a preset limit.

A sorter-stacker arrangement for sheet part pieces (17) such as are produced by a punch press (18), in which part pieces are unloaded onto a sorter table (50) in a located position against any one of a row of stops (52), and conveyed along an X-axis as by translation of the conveyor table therealong. A pair of storage racks (36) are disposed on opposite sides of the sorter table (50), each having a vertical array of open spaces facing the sorter table (50). The sorter table (50) is elevated to the preselected position, and advanced into the appropriate storage space (38). After lowering of the stripper gates (104), the sorter table (50) is retracted to align the part piece 17 by contact of the stripper gate (104) with the inside edge of the part piece (17) and stripped on to the stack as the sorter table (50) returns to the central position.

A punch press (10) having a punching head (30) which includes a large eccentric crankshaft (42) for operating selected punches (32). The large eccentric crankshaft (42) withdraws the punch (32) into an upper tool support (92) for a relatively large portion of the crankshaft rotation. The crankshaft (42) is connected to a selected punch (32) by a suitable mechanical interposer. The upper tool support (92) is provided to hold a variety of punches (32) and is movable to bring a selected punch (32) into position for being operated by the punching head (30). A mechanism is provided for relative positioning of a workpiece and the punching head (30). Since the punch (32) is withdrawn within the upper tool support (92) for a relatively large portion of the crankshaft (42) rotation the movement of the workpiece can take place while the selected punch is moving but withdrawn within the upper tool support (92).

A marking tool holder (10) for a punch press, in which a plurality of marking tools (46) are mounted in an indexing carrier (38) for selective activation by the press ram (14). A non-positive connection effects driving of the preselected marking tool (46) to eliminate the need for precise adjustment of the marking tool position. In a first embodiment, a pair of very stiff springs (138) are interposed between a ram engaged plunger (124) and a striker (70), while in the second embodiment, a striker mass (158) attached to the striker (70) and carried in a body member (60) which is accelerated by the ram (14) to generate kinetic energy converted into a marking pressure when the marking tool (46) impacts the workpiece (W).
