Title: Method of replacing a punch of a punch tool assembly using an assembly jig
Inventor: DRIES EDWARD A
IPC: B21D45/00
Filed: 1999-02-26
Abstract: A method for replacing a punch 12 of a punch tool assembly 10 involves providing an assembly jig 232, comprising a base 236 having spatially separated plates 238, 240 and a plunger rod 234 which extends upwards from the base. The punch tool assembly 10 has a punch 12 which is positioned within a guide 14 and a punch driver (28) which is connected to the punch by a quick release mechanism. A punch head (46) is connected to the driver (28) and has an axial bore (198). The method involves inverting the punch tool assembly 10, so that punch 12 is positioned above punch head (46), and placing it on to assembly jig 232. Plunger rod 234 of jig 232 is inserted in to bore (198) of the punch head (46) and the punch tool assembly 10 is urged towards base 236. Retaining knob (30) and ball bearing holder (36) thereby move deeper in to bearing sleeve (38). This causes the ball bearings (202) to move in to the deep portions (158) of the sleeve's (38) circumferential groove (156). Evidently, as retaining knob (30) no longer engages with bearings (202), the punch 12 can be moved from within guide (14) and hence from the punch driver (28). Also see Figs 25B and D.

Title: Synchronisation between pipelines in a data processing apparatus by using tokens
Inventor: EVANS MARTIN ROBERT
IPC: G06F9/38
Filed: 2002-09-04
Abstract: The present invention provides a technique for synchronisation between pipelines in a data processing apparatus. The data processing apparatus comprises a main processor operable to execute a sequence of instructions, the main processor comprising a first pipeline having a first plurality of pipeline stages, and a coprocessor operable to execute coprocessor instructions in said sequence of instructions. The coprocessor comprises a second pipeline having a second plurality of pipeline stages, and each coprocessor instruction is arranged to be routed through both the first pipeline and the second pipeline. Furthermore, at least one synchronising queue is provided coupling a predetermined pipeline stage in one of the pipelines with a partner pipeline stage in the other of the pipelines, the predetermined pipeline stage being operable to cause a token to be placed in the synchronising queue when processing a coprocessor instruction, and the partner pipeline stage being operable to process that coprocessor instruction upon receipt of the token from the synchronising queue. By this approach, the first and second pipelines are synchronised between the predetermined pipeline stage and the partner pipeline stage, and hence ensures that the pipelines are correctly synchronised for crucial transfers of information without requiring that strict synchronisation at all stages is necessary.

Title: Removal of an acid
Inventor: TURNER ANDREW DEREK
IPC: B01D61/44
Filed: 2002-12-28
Abstract: A weak acid that may be corrosive or oxidisable is removed in a plant that includes at least one flow channel (12) for the liquid to be treated, the flow channel (12) being defined between membranes (A, B) and being filled with a fluid-permeable bed (14) of anionic ion-exchange material, and there being a concentrate chamber (20) adjacent to the flow channel (12). Electrodes (16, 18) are arranged to apply an electric field transverse to the flow direction so as to urge anions from each flow channel (12) through an ion-permeable membrane (A) into the adjacent concentrate chamber (20). The membrane (B) at the other side of the flow channel is bipolar, and so permeable to neither anions nor cations; instead water is split into hydrogen and hydroxyl ions within the bipolar membrane, and these emerge from the opposite faces of the membrane. This ensures that there is an adequate concentration of hydroxyl ions in the flow channel (12) to ensure that the weak acid is at least partly ionised. The anode (16) may be separated from an adjacent concentrate chamber (20) by another bipolar membrane, either to protect the anode from corrosion, or to prevent oxidation of the acid.
