Patent GB-2301126-A (GB)
Title: Rotary cone rock bit
Inventor: ENSMINGER JERRY
IPC: E21B10/18
Filed: 1996-05-10
Abstract: A rotary cone rock bit 10 for use in earthen formations utilises diffusion type nozzles 30 which are located at the outer region of a dome portion 40 of the rock bit resulting in a diffused flow 42 of fluid without turbulence leaving the exit end 36 of the nozzle 30. The diffused spray 42 of fluid at a lesser velocity will better clean the rotary cones 22 by moving the fluid closer to the cones without erosive damage to the cones or loss of cutter inserts or milled teeth. The diffused spray will additionally cover a larger area of a borehole bottom resulting in better bottom hole cleaning.
Patent GB-2303157-A (GB)
Title: Plugging a well
Inventor: MYERS WILLIAM D
IPC: E21B43/116
Filed: 1996-07-03
Abstract: A one-trip system for placement and setting a downhole packer or plug is disclosed. The packer is settable in a variety of ways, including hydraulically, acoustically by pressure pulse signals, or some combination. Use of hydraulic pressure triggers a pressure-creating reaction to initiate the setting of the packer. The setting mechanism for the packer breaks clear of the packer upon setting and allows a tubing-conveyed perforating gun, which is already preassembled as part of the string, to be accurately positioned and fired.

Title: Friction plug extrusion
Inventor: THOMAS WAYNE MORRIS
IPC: B23K20/12
Filed: 1996-10-14
Abstract: A method of forming a plug-like member comprises placing a consumable member (5) in a bore (7) of a substrate (8) so as to leave a clearance between the consumable member and the wall of the bore. Relative movement is caused between the consumable member (5) and the substrate (8) while urging them together to generate frictional heat and fully plasticizing the consumable member across the bore in a plasticised region which progresses along the consumable member in a direction opposite to the urging direction. The plasticised material (9) is allowed to solidify so as to form the plug. Each of the consumable member and bore are tapered at different angles. Alternatively the plug may have a different cross section from the bore, eg hexagonal.

Patent GB-2317995-A (GB)
Title: Antenna assembly
Inventor: PAULICK THOMAS E
IPC: H01Q1/08
Filed: 1997-08-29
Abstract: A novel antenna arrangement enables the fully automated insertion of an antenna assembly in a communication device (100), such as a cellular radio telephone. A mounting bracket (112) for the antenna assembly is designed to stand in place to enable reflowing of solder to attach the mounting bracket to a circuit board 106. A sleeve (130) and corresponding head (132) of the antenna assembly operatively couple to enable insertion of the sleeve into the mounting bracket, while preventing removal of the sleeve with the head. The lower surface of the head is designed to enable the clockwise rotation of the sleeve, while preventing the counterclockwise rotation of the sleeve. This is achieved by forming the lower surface into two ramped surfaces separated by a gap, and each ending in a radial step. The sleeve (130) upper surface has a corresponding mating form, such that clockwise rotation of the head (32) screws the sleeve (130) into the bracket (112), whereas counter-clockwise rotation only induces slip.

IPC: H04M1/02
Filed: 1997-10-13
Abstract: A battery charger has a housing 302, 304 containing a charging current source coupled to contact pins disposed on the housing for plugging into a standard wall or floor mounted mains socket, and the output of the charging current source can be coupled to a battery in a remote electrical or electronic apparatus (such as a cellular radio telephone or portable personal computer) by means of a connector 314 on a cable 313 which can be wound around a reel 310 for storage in the housing when not in use. The cable reel 310 may be non-rotatable relative to the housing. Access to the cable reel 310 may be provided by means of a cover 350 which is pivoted to the housing, or slidably mounted (Figs. 10a, 10b) or removable (Fig. 8). Alternatively, a side plate of the cable reel may form part of the outer surface of the housing, and the reel can be pulled from a concealed position within the housing to an exposed position for winding or unwinding the cable (Figs.3-5). A recess (6, Figs.1,2) may be provided in the housing to receive a spare battery, or the whole telephone, for charging. The recess is oriented so that a battery inserted therein is at an angle of about 45 degrees to the vertical irrespective of whether the charger is plugged into a wall socket (Fig.6) or a floor socket (Fig.7), whereby the battery remains in the recess (6) due to gravity. A slidable cover (9) fits over the recess (6) when it is not in use.

Patent GB-2328593-A (GB)
Title: Controlling logical queue depth in an input buffer of an ATM switch
Inventor: HEO JEONG WON
IPC: H04L12/931
Filed: 1998-06-11
Abstract: An input butter 22 of an ATM switch has a number of logical queues each for storing cells of a different priority (1,2....P). The logical queue depth (fill level) of each queue varies according to traffic conditions and incoming cells of a particular priority may be lost if there is no free space in the logical queue for that priority. To reduce the amount of cell loss the allocation of buffer space to each logical queue (logical queue size) is dynamically controlled according to a back pressure signal from the switch element 23 and the current depth being occupied in that logical queue. If the occurrence rate of a backpressure signal reaches a threshold and the logical queue depth reaches a threshold for a particular queue then an algorithm checks to see it there is unused buffer space in one of the other logical queues. If so this space is reallocated to the overfull logical queue.
