Patent GB-2408764-A (GB)
Title: Cementing through a side pocket mandrel
Inventor: CHAPMAN WALTER R
IPC: E21B21/10
Filed: 2003-10-01
Abstract: Well completion cement may be pumped through a side pocket mandrel that includes parallel rows of filler sections to exclude cement from void space within the side pocket tube. The filler sections are drilled with cross-flow jet channels and surface upsets to stimulate scrubbing turbulence by well working fluid behind a cement wiper plug. The wiper plug includes leading and trailing groups of wiper discs secured to an elongated shaft. The two wiper groups are separated by a distance that permits the leading seal group to gain traction seal before the push seal on the trailing wiper group is lost. A spring centralizer spans a center section of the shaft between the two wiper groups to maintain axial alignment of the shaft as the plug traverses the length of a mandrel.

Title: Rotary switch with ratcheting feature
Inventor: FOSTER WILLIAM L
IPC: H01H3/08
Filed: 2005-02-16
Abstract: A rotary switch (102) for an electronic device (100) includes a bump stop (104) that triggers a ratcheting feature when hit. The range of the rotary switch (102) is expanded via the ratcheting feature. The ratcheting feature inhibits scrolling through a device parameter in one rotation direction and enables scrolling through the device parameter in the opposite rotation direction. Depending on which direction the bump stop (104) is hit, the parameter is either incremented or decremented. The range of the rotary switch can also be expanded by modifying the step size of the rotary switch based on the range of a selected parameter (504). The coarse step is then narrowed with each change in rotation direction (510, 518) based on current, previous and useable switch positions (512, 514).

Title: Current sensing circuit with a current-compensated drain voltage regulation
Inventor: WADHWA SAMEER
IPC: G11C7/06
Filed: 2006-03-22
Abstract: The present invention facilitales more accurate data reads by compensating for parasitic behavior (662) - thus regulating the voltage at the drain (610) of a core memory cell (604) rather than at the output of a sensing circuit. More particularly, respective voltages at one or more nodes (660), such as the start of a bitline at a sensing circuit, for example, are adjusted to compensate for voltage drops that may occur due to parasitic behavior (662). Maintaining the substantially constant voltage levels at core memory cells allows comparisons to be made under ideal conditions while reducing the side leakages in virtual ground schemes. This mitigates, margin loss and facilitates more reliable data sensing.

Title: Mango-pod extractors
Inventor: BRAZIER NIGEL
IPC: A47J23/00
Filed: 2007-09-21
Abstract: A mango-pod extractor has a cutter 3 with a one-piece wall 4 of elongate tubular form of oval cross-section and having curved cutting-edges 12 for piercing the mango M. The wall 4 is expandable resiliently in the minor-axis dimension for close conformal cutting over the surface of the pod P within the pierced mango M. A transverse spindle 9 in the minor-axis dimension slides in slots 7,8 lengthwise of the wall 4, and carries springs 11 that squeeze front and back faces 5,6 of the wall 4 in towards one another against the resilience of the wall 4. The spindle 9 moves up the slots 7,8 as piercing progresses, allowing the wall 4 to expand resiliently round the pod P for retention of it within the cutter 3 upon withdrawal from the mango M. Sliding of the spindle 9 down the slots 7,8 discharges the pod P. Instead of a one-piece construction, the wall 4 may be replaced by bowed shells that are urged resiliently towards mutual abutment along their longitudinal edges.

In this way, a reliable electrical connection may be formed between the sleeves of mating connectors. This connecting functionality may be incorporated within the length of a keying arrangement comprising a circumferential extending protuberance 21 used for aligning the connectors with respect to each other, thereby allowing for miniaturisation.

Title: Hybrid asymmetric / symmetric encryption scheme which obviates padding
Inventor: WHITAKER BENJIMAN JOHN DICKSON
IPC: H04L9/08
Filed: 2008-05-06
Abstract: The entire payload of a message is encrypted using a symmetric key. The symmetric key and the symmetrically encrypted payload are concatenated and asymmetric encryption is applied to the symmetric key and at least the first part of the payload. If the length of the concatenation exceeds the block length of the asymmetric encryption then the remainder of the payload which does not fit in the block length can be transmitted without public key protection because it is already protected by the symmetric key. In this case the symmetric key replaces the random padding used in PKCS#1 v1.5, providing efficiency gains. If the payload can fit within a single asymmetric encryption block, along with the symmetric key, then the remainder of the block is padded before asymmetric encryption. The payload preferably includes, in addition to plaintext data, a message authentication code (MAC) or similar checksum. The symmetric key is preferably a session key. The invention may be applied to communication between client and server. The encryption scheme disclosed is said to be "probabilistic", and provides protection against plain-text aware attacks.

Title: Patterned die attach layer
Inventor: PELTZ LEORA
IPC: H01L21/60
Filed: 2008-06-05
Abstract: A semiconductor die 22 is attached to a packaging substrate 24 by a patterned layer 32 of conductive metal that includes voids 38. The voids 38 provide a space into which the metal may expand when heated in order to reduce mechanical stress on the bonds caused by mismatches in the thermal coefficients of thermal expansion of the die, the conductive metal bond layer and the substrate. An additional coating (36 figure 5) of conductive metal may be flowed over the bond lines (37) to reinforce the bonds. The patterned die attach layer 32 may be in the form of evenly spaced wires 34, or islands (38a, fig 6) of conductive material. In other embodiments, the die attach layer 32 is formed with irregular openings in the form of depressions (38g, fig 10).
