In preferred embodiments, when the shell is in the open position, the battery 24 is accessible for replacement. This obviates the need for a separate flap to provide access to the battery. With the battery positioned in the middle of the volume inside the shell a degree of electrical isolation is provided which reduces the possibility of interference.
Patent GB-2316690-A (GB)
Title: Lyocell fabric treatment
Inventor: BURROW THOMAS RICHARD
IPC: D06M23/00
Filed: 1996-09-03
Abstract: Fabric comprising yarns comprising lyocell fibres is treated with a swelling agent, preferably aqueous sodium hydroxide, whilst in a form in which it is unrestrained and free to shrink. The swelling agent causes the lyocell fibres to swell without destroying their structure by dissolution, the amount of swelling being in excess of the amount to which the lyocell fibres will swell during exposure to all subsequent wet processing of the fabric. The effect of the swelling agent is then diluted with water so as substantially to set the yarns in the fabric in the positions relative to one another that they have in the swollen condition. The resulting fabrics are very much less affected by creasing than untreated fabrics are and do not suffer as much from the formation of lines during subsequent wet processing.

Title: Inter-network call handover
Inventor: USKELA SAMI
IPC: H04W36/14
Filed: 1998-07-28
Abstract: A method for performing handover of a fixed or moving mobile station 39 communicating in a first call 47 via a first network NW1 to communication in a second call 49 via a second network NW2, comprising: generating a request for handover, (either at the mobile or first network), establishing the second call 49 between the first network and the mobile station via the second network and transferring data communication between the mobile station and the first network from the first call 47 to the second call 49. The first call 47 is preferably released after the data communication transfer. In one embodiment (figures 4, 5), where mobile terminated calls are used, the mobile sends to the first network, information defining the identification number of the mobile in the second network and the first network requests a call 49 to this number via the second network. In another embodiment (figures 6,7), where mobile originated calls are used, the first network assigns a handover number to the handover and sends this information to the mobile which then makes a call 49 to the second network which includes this handover number. The second network can then use this handover number to report to the first network that the call 49 has been set up and handover can be completed. Invention preferably relates to radio communication in cellular telephone networks where the first network is an IMT-2000 network and the second network a PDC network. Allows new incomplete networks to increase coverage by handover to complete old networks.

Title: Fluid seal in a plunger and barrel assembly
Inventor: BEATTY DAVID J
IPC: F02M59/44
Filed: 1998-10-19
Abstract: A plunger and barrel assembly comprises a plunger 120 and a barrel defining a plunger bore 311. The plunger 120 has a pressure end face which, along with the bore 311, defines a pressurization chamber 317. Fluid seal O-ring 24 is positioned in an indentation in the plunger side face. A groove which provides a receiver volume 125 is located in the plunger side face between the O-ring 24 and the pressure end face. Alternatively the receiver volume 125 may be located in the wall of the bore (figure 3). The receiver volume 125 reduces/attenuates the pressure experienced by the O-ring 24 thus lengthening its working life. The pressure acting on the O-ring 24 is further reduced by placing compressible member 130, which defines a trapped volume filled with gas, in the receiver volume 125. The compressible member 130 can come in a variety of cross-sections and configurations (figures 5, 6). The receiver volume 125 can also work in conjunction with a passageway 319 to further relieve pressure. This assembly can be applied particularly to a intensifier plunger or needle valve or a fuel injector.
