Patent GB-2322970-A (GB)
Title: Process for single mask C4 solder bump fabrication
Inventor: CRAFTS DOUGLAS E
IPC: H01L23/485
Filed: 1995-12-18
Abstract: A method for removing Ball Limiting Metallurgy (BLM) layers (14, 15) from the surface of a wafer (10) in the presence of Pb/Sn solder bumps (17). In one embodiment, the BLM comprises two layers: titanium (14) and copper (15). After Pb/Sn solder-bumps (17) have been formed over the electrical contact pads (12) of the wafer (10), the BLM copper layer (15) is etched with a H 2 SO 4 +H 2 O 2 +H 2 O solution. While removing the copper layer (15), the H 2 SO 4 +H 2 O 2 +H 2 O etchant also reacts with the Pb/Sn solder bumps (17) to form a thin PbO protective layer (18) over the surface of the bumps (17). When the copper layer (15) has been etched away, the titanium layer (14) is etched with a CH 3 COOH+NH 4 F+H 2 O solution. The PbO layer (18) formed over the surface of the Pb/Sn solder bumps (17) remains insoluble when exposed to the CH 3 COOH+NH 4 F+H 2 O etchant, thereby preventing the solder bumps (17) from being etched in the presence of the CH 3 COOH+NH 4 F+H 2 O etchant. When the titanium etch is complete, the PbO layer (18) is removed from the surface of the Pb/Sn solder bumps (17) by exposing the bumps (17) to an HCI+NH 2 CSNH 2 +NH 4 Cl+H 2 O solution.

Title: Data symbol counting device and synchronising device
Inventor: WALLER ARTHUR SIMON
IPC: H04N21/242
Filed: 1998-09-30
Abstract: A device for counting the number of consecutive data symbols in a stream of data bytes comprises a main counter for maintaining a count of consecutive data bytes (incrementing or decrementing), and an adjustment means for incrementing/decrementing the count of the main counter by and adjustment value after every occurrence of a predetermined number of consecutive data bytes. The adjustment value is determined according to the ratio of the number of bits in the bytes to the number of bits in the symbols such that the count represents a count of data symbols. A synchronising device generates a synchronisation signal from a received MPEG data stream with a MAC message containing an Upstream Slot Marker Pointer. The synchronising device includes the above counting device, a controller for starting the main counter according to a received MPEG synchronisation signal and synchronising means for generating the synchronisation signal once the main counter has counted the number of symbols indicated by the Upstream Slot Marker Pointer.
Patent GB-2334052-A (GB)
Title: Apparatus and method for self adjusting downhole signal communication
Inventor: GRUENHAGEN HARTMUT
IPC: G08B21/00
Filed: 1999-02-05
Abstract: An apparatus for sending signals downhole during drilling operations uses a main pump 15 to pump mud from a mud pit 13 at a substantially constant flow rate. The bulk of the pumped mud goes downhole to maintain adequate circulation for the drill bit 12. A bypass pipe 23 is provided with a shut-off valve 24 that is controlled by an electronic controller 25. By pulsing the opening and closing of the shut-off valve 24, the volumetric flow downhole is pulsed. The pulse amplitude and duration can be controlled. These pulses in the flow rate are detected by a suitable downhole device such as a flow rate measurement device, a pressure detector or a turbine. The initial "wake-up" pulse is made long enough so that the detection device downhole is always able to detect it. Subsequent to this wake-up pulse, adjustments are made to the pulse duration, in steps of about 2 seconds, for the smallest pulse period that is detectable downhole. In addition, the amplitude of the pulses is also controlled by regulating the maximum flow through the shut-off valve. The pulses are modulated by a binary sequence of numbers corresponding to the data to be transmitted.

Title: Internal support structure for an undulate membrane electrode assembly in an electrochemical cell
Inventor: MCLEAN GERARD FRANCIS
IPC: H01M8/02
Filed: 1999-07-01
Abstract: A proton exchange membrane (PEM)-type fuel cell is formed from layered undulate MEA structures and separator plates alternating with each other in the stack dimension so that each layered MEA structure is disposed between and attached to an associated pair of separator plates so as to form at least one discrete conduit on each side of each layered MEA structure through which conduit reactant gas may be circulated.

Title: Starting arrangements for discharge lamps
Inventor: TYSON LAWRENCE SAMUEL
IPC: H01J61/56
Filed: 1999-11-18
Abstract: A luminaire comprises a control circuit 43, a separable discharge lamp 45, and a split resonant circuit having a control reactance 44 in the control 43 and a lamp reactance 48 mounted in or on the lamp 45. The control 43 applies a voltage at the resonant frequency of the circuit 44, 48 in order to generate a high voltage to start the lamp 45, whereupon the lamp reactance 48 is effectively short circuited by the discharge within the lamp. The lamp reactance 48 is capacitive, and may be mounted in thermal proximity to the lamp discharge. The lamp reactance (132, Fig.6) may be mounted in an outer envelope (102) of the lamp, or adjacent an outside surface of the outer envelope (Fig.6A), or in a pinch of the outer envelope, or in an enclosure between upper and lower pinches (Fig.7), or in a lamp cap. The lamp reactance 48 may have a positive or negative temperature dependent coefficient of impedance arranged to prevent the control 43 from attempting to restart the lamp until it has cooled. The control 43 may initially operate at a high frequency (ST-ON, Fig.10) above the resonant frequency of circuit 44, 48, then sweep through the lamp-starting resonant frequency (PF) to a dwell point (DWP) at frequency below the resonant frequency. The control stays at the dwell point frequency for a considerably longer period than the sweep time, in order to allow the lamp discharge to stabilise, and then the frequency is increased to a lamp operating frequency (SF) which is above the starting resonant frequency but below the initial high frequency (ST-ON).

Patent GB-191420443-A (GB)
IPC: D01G15/38
Abstract: 20,443. Dronsfield, J. Oct. 2. Milling - machines. - The ends of flat-bars, for carding-engines, which engage with the bends or other guiding-parts, are milled in a continuous-action milling-machine with a rotary work-carrier. The required shape is derived from a former. A hollow shaft 10, Figs. 3 and 11, carries two spiders 11 having interchangeable sealing-blocks 12 to accommodate flat-bars of various types. The clamping - plates 14, Fig. 8, are varied by springs when the nut is slackened to facilitate the removal of a finished and the insertion of a new bar. This change takes place during the milling of a bar on another of the arms. Worm-wheel sections 33 engage a worm itself driven by worm-gearing from the main shaft 22, to impart feed during milling. The spider is turned bv hand from one position to the next. A shaft 16 carries a fixed lever 35 and a loose lever 36 angularly adjustable with respect to the lever 35 by a worm and sector 40 and bolt and slot 37. Interchangeable formers F engage adjustable abutments 44 on the driving-spider and so work the shaft 16, which carries the cutter bracket 17, according to the profile required. Weighted arms 47 on the shaft 16 and a spring 38 maintain contact between the formers and abutments. An adjustable bolt 39 passing through a nut 36<x> limits the motion. To enable the cutters 19 to be set separately, the shaft 16 is made in two parts connected by an angularly adjustable coupling. For gauging the amount of adjustment of the cut, the worm 40 may be replaced by a worm 40<x>, Fig. 6, having an angularly adjustable graduated barrel 42 cooperating with an index mark on a plate 44. After setting the zero, the barrel is locked by a screw and plug 43<x>. The spindles carrying the cutters 19 are geared at 26, Fig. 8, to a cross-shaft 20 driven through a compound wheel 24, loose on the shaft 16, from the main shaft. Fig. 2 shows a modified arrangement of drive.
