Title: Space charge control in a tandem ion trapping arrangement
Inventor: GREEN MARTIN
IPC: H01J49/00
Filed: 2008-09-03
Abstract: A mass spectrometer is disclosed comprising a first high capacity storage ion trap 2 arranged upstream of a high performance analytical ion trap 3. According to an embodiment ions are simultaneously scanned from both the first and second ion trap 2 and 3. At any instant in time the quantity of charge present within the second ion trap 3 is limited or restricted so that the second ion trap 3 does not suffer from space charge saturation effects and hence the performance of the second ion trap 3 is not degraded. Preferably ions are mass selectively ejected from both the first and second ion traps. Alternatively, ions may be attenuated as they are being transmitted from the first ion trap 2 to the second ion trap 3.

Title: Updating corrupted local working registers in a multi-staged pipelined execution unit by refreshing from the last state hold a global checkpoint array
Inventor: GERWIG GUENTER
IPC: G06F9/38
Filed: 2008-12-19
Abstract: Disclosed is a method for updating corrupted local working registers in a multi-staged pipeline structure, after an exception. The registers being needed to execute complex instructions in an execution unit, e.g. a floating-point unit, whose deep pipeline structure comprises a set of local working registers. The pipeline being such data dependencies among different instructions referencing the same registers exist. The method operates by refreshing any corrupted local working register from the last architected state hold in a global checkpoint array. The registers may also be updated using the hardware infrastructure of the execution unit when the data is corrupted by early pipeline updates. A master copy of all local working registers may be held in the checkpoint array, which is not updated in exception cases. All the early loads or early register updates form instructions that were issued after an instruction got into the exception may be refreshed.

Title: Improvements in sheet feeding apparatus
Inventor: BAGLEY ERIC JOHN
IPC: B65H3/10
Filed: 1962-03-16
Abstract: 963,341. Feeding sheets. SOLARTRON ELECTRONIC GROUP Ltd. June 17, 1963 [March 16 1962] No. 10210/62. Heading B6B. Sheets such as footballpool coupons in a stack 12 are withdrawn from the bottom of the stack in a stream and presented to a suction roller 52 which separates them one by one from the bottom of the stream. The stack 12 rests on an incline d base 10 of a magazine, and a stream of sheets is fed beneath a front plate 16 by the actions of a conveyer belt 18, and a rotary jogger 34 comprising a square prism which projects into the magazine. The belt 18 feeds the stream to a second belt 22 which presents the sheets to the suction roller 52, the belt 18 having a greater coefficient of friction than the belt 22 and travelling at a slower speed. A common belt 24 driven from an infinitely-variable gear 30 drives the conveyer belts 18, 22; the jogger 34 is driven from an infinitely-variable gear 38 by a belt 36; and both gears 30, 38 are driven from a common motor by a belt 40. The greater tractive effect of the belt 18 causes the stream of sheets to build up on the belt 22, and the thickness of the stream is controlled by a feeler 46 which operates a switch 48 to cause the motor 42 to run at half speed until the stream thickness drops by a predetermined amount. More than two conveyer belts may be used. The sheets stream on the upper face of a block 50 containing the suction roller 52, which feeds the bottom sheet to feed rollers 62, 64 which feeds it on to a delivery conveyer belt 66. The suction passages in the roller 52 are arranged so that a sheet is released by that roller when the leading edge is between the feed rollers 62, 64, so that the latter can feed the sheet at a faster rate. To ensure that only one sheet is separated by the suction roller 52, a reversely rotating friction roller 76 is arranged above the roller 52 to push back surplus sheets. The roller 76 has disc portions of enlarged diameter opposed to cylindrical grooves in the roller 52, so that sheets passing between these rollers are corrugated. The rollers 52, 76, 62 and 64 and conveyer 66 can be driven from one motor by way of belts or gears. Guides.-The periphery of the suction roller 52 where it protrudes from the upper face of the block 50 is bridged by thin steel strips to prevent sheets entering the block, the roller being grooved to accept these strips. On the exit side of the feed rollers 62, 64, the sheets are guided through a throat formed by a fixed extension 68 of the block 50 and a member 70 which encircles the roller 62 and is received in annular grooves therein: if a sheet crumples in the throat, the member 70 will pivot upwardly so that the sheet can be ejected and the sheet feed will not be jammed. Specification 919,791 is referred to.

The invention relates to a method of assembly of a well-drilling turbine of the kind comprising a stack of inner stator parts held under compression within an outer stator casing held under tension, the parts together forming a prestressed assembly, and being stressed by means of a jack device one part of which is screwed to an end portion of the outer stator casing and the other part of which is applied to the stack of stator parts, the parts being locked together after prestressing and the jack then removed. The turbine shown in Fig. 1 comprises an outer stator casing 7 within which the stator elements, also a bearing support 9 having webs 10, are stacked. A screwed sleeve or joint 8 is secured to the outer casing 7 by means of a conical screw connection and the hydraulic jack device 13 is secured to the sleeve 8 by means of the conical screw connection 12. The jack comprises a piston 16 disposed within cylinder 14 the piston 16 being provided with a cylindrical pusher member 17 which extends around the rotor shaft 1 and lock nuts 2, 3, 4, to abut against the webs 10 of the bearing member 9. When pressure fluid is applied to the cylinder 14, the pusher member 17 is forced downwardly whereby the inner stator elements are stressed in compression and at the same time the outer stator casing 7 is stressed in tension. The parts are locked in position by means of a locking ring member 18 which is screwed into the sleeve 8 and engages the ring member 11 disposed adjacent the bearing member 9.
