Title: Ball and socket fluid coupling
Inventor: CHALLENDER GARY BERNARD
IPC: F16L27/06
Filed: 2004-04-23
Abstract: An articulating ball-and-socket fluid coupling includes a ball body 12, a socket body 14, a primary retainer structure 16, an annular seal assembly and a secondary retainer structure 21. The primary retainer structure 16 has a shaft 56 extending through the ball and socket bodies 12, 14 to connect the ball body 12 and the socket body 14 together while permitting the ball body 12 and the socket body 14 to articulate relative to each other. The secondary retainer structure 21 includes an annular member 58 disposed in a ball receiving conduit portion 54 of the socket member and connected to the socket body 14 at or adjacent to an opening into the ball receiving conduit portion 54. The annular member 58 has an inner secondary retainer diameter less than a spherical diameter of a partially spherical exterior surface defining a ball portion 22 of the ball body 12 so that the secondary retainer structure 21 retains the ball body 12 and the socket body 14 connected if the primary retainer structure fails 16.

Title: Battery charger which prevents overheating
Inventor: SHUM KING MO
IPC: H02J7/00
Filed: 2004-04-26
Abstract: A battery charger (10) for simultaneously charging a plurality of rechargeable batteries for example of AA or AAA size comprises a base (11) having a plurality of recesses (36, 38, 40, 42) each for receiving a respective battery. The recesses are positioned such that the batteries are well spaced apart on the base (11). This arrangement, coupled with a suitable charging circuit, allows such batteries to be fully charged in up to about half the time previously considered to be possible without damaging or destroying the batteries. It has been found that by mounting the batteries on the base of a charger such that they are substantially exposed and spaced apart, an average charging current of up to about twice that previously considered to be possible can be applied without overheating the batteries.

Title: Resistive or capacitive position transducer
Inventor: LENNING ANDERS
IPC: G01D5/24
Filed: 2004-08-20
Abstract: A sensor 12 measures the position of one object 11 relative to another 15 using the position of a bend 10 in a flexible element 1 linking the two. The element has an electrical characteristic, which may be resistance or capacitance, which varies according to the bend position. The flexible strip may have a resistivity that varies along is length, for example by varying the cross section of the strip; or a capacitance that varies along its length, for example by varying the thickness of a dielectric. The bend is detected via resistance using a material which increases its resistance when bent, or via capacitance using a pair of conductors which are brought closer by the compression of a dielectric between them. The device may be deployed with the flexible element bent through 180 degrees, or passing over a roller or in a rotatable shaft to measure angular displacement.

Title: A radio transmitter power control arrangement
Inventor: HANNA WISAM A
IPC: H03G3/20
Filed: 2005-05-26
Abstract: A radio transmitter 100, e.g. for a base station of a cellular communications system, comprises a power amplifier 103 for generating a radio frequency signal to be radiated from an antenna 105. A power supply means 107, 109 supplies power to the rf power amplifier 103.

Patent GB-2431528-A (GB)
Title: Electronic commutator circuits
Inventor: CRANE ALLAN DAVID
IPC: H02P6/14
Filed: 2005-10-18
Abstract: The electronic commutator circuits of the present brushless motor provide forced commutation means that can be embedded within a known electronic commutator to overcome its low speed torque limitation. The forced commutation circuitry consists of forced commutation enhancements to the basic switched stage using a pair of thyristors 1 and 4. Capacitors 3 and 6 may be pre-charged and synchronised to supplement coil voltages when discharged, thereby reducing commutation overlap duration and maximising the turn-off time available to allow the thyristors 1 and 4 to attain forward blocking capability. Two methods of providing such a capacitive discharge can be used. The first method initiates the capacitive discharge by the same thyristor that will carry the current following the commutation. The second method initiates the capacitive discharge by an auxiliary thyristor.

Title: Device for carrying sleeved garments compactly with reduced creasing
Inventor: SMITH PAUL
IPC: A47G25/54
Filed: 2006-04-24
Abstract: A sleeved garment is laid upon an opened bag (1). Aprons made from crease-resistant material (2,6) attach to the bag (1) and fold over the upper and lower parts of a garment, giving a continuous surface for the garments to fold over. Reinforced areas of anti-crease material (3,7) in these aprons (2,6) cover garments at the fold-lines, creating wide folding radii that prevent sharp creases along the fold-lines. The reinforced areas (3,7) taper in thickness away from the fold-lines, minimising secondary edges within the carrier (1) thus preventing secondary creasing. Garments in the carrier (1) can be folded up to 3 times. Reinforced non-crease material along the device's 3 main fold lines (4,5,7) help prevent creasing. The carrier (1) can be made with strong durable material in discrete panels, so that its outer surfaces protect the clothes inside.
