IPC: F16L55/18
Filed: 2000-07-26
Abstract: A device tor repairing a pipe includes an elongate insulated handle 10, which can have a number of different attachments connected to one of its ends. These attachments include a drill 25 to drill an aperture into the pipe and an injector head (31, figure 2) to inject sealant into the pipe from an above ground position. A tool 21 may also be attached to the handle 10 for excavating the ground to gain access to the pipe to be repaired. If the pipe is 'live', then a tapping adaptor (50-54, figure 4) may be attached to the end of the handle, and a nipple arrangement (63, figures 5 and 6) may be fitted to the tapped aperture, prior to the injection of the sealant. The handle 10 is preferable hollow, and has a compressed air inlet 14 and associated nipple 15. Preferably, a trigger device 16 controlled by handle 17 receives compressed air to power the various attachments.

Title: Weldless support structure and electrical connections in a hid lamp
Inventor: JOHANNING JEFFREY L
IPC: H01J61/82
Filed: 2000-12-13
Abstract: In a high intensity discharge lamp having an arc tube 42 supported within an outer envelope 44, the arc tube is supported by a wire support 50 having legs 64 received in apertures (Fig. 6b, 70) defined by a clamp (Fig. 6b, 58) which extends around a glass stem 56 through which extend conductor wires 60 connecting the arc tube electrically to connectors on the exterior of the outer envelope. The wire support 50 is held in place by an inward protrusion of the outer envelope, at its end opposite the stem 56, engaging in a loop 62 of the wire support 50. Furthermore, electrical connection between, on the one hand, each terminal lead 90, 92 extends into and from the arc tube 42 and, on the other hand, the respective conductor lead 60 extending from the glass stem 56 is effected, in each case, by a connector 94, 9b in the form of a wire having a coil (Fig. 11, 104) at one end which receives the respective lead 60 and a coil (Fig. 11, 106) at its other end which receives the respective terminal lead 90, 92.

Title: Power supply circuit for an electroluminescent lamp
Inventor: JONES PHILIP MATTHEW
IPC: G09G3/30
Filed: 2001-02-26
Abstract: A high voltage AC power supply circuit for a capacitive load C<SB>L</SB>, such as an electroluminescent lamp, includes a low voltage DC supply, an inductor L and a FET S in series. The FET S can be pulsed so that the inductor L generates a voltage to charge the capacitive load C<SB>L</SB> via an H-bridge H, which is in parallel with the FET S. A diode D prevents current discharging from the capacitive load C<SB>L</SB> while the FET S is closed. The total capacitance downstream of the diode D and in parallel with the capacitive load C<SB>L</SB> is less than the capacitive load C<SB>L</SB>, so that when the polarity of the H-bridge is reversed, the voltage across the H-bridge collapses to earth and the capacitive load C<SB>L</SB> is discharged via the low voltage DC supply. The circuit has a lower power consumption than circuits which a employ a large smoothing capacitor in parallel with the H-bridge.

Filed: 2003-05-28
Abstract: A mobile wireless device operable to install code on a removable medium, in which the device is programmed to calculate and store a digest of this code into a persistent non-removable store inside the device. When the removable medium is plugged back, and when the code is invoked, the device recalculates a digest from the code it wants to load from the removable medium and compares it with the one stored inside the persistent non-removable store. If they do not match, the code has been tampered with and therefore cannot be trusted by the device. The digest is accessible only by components in the Trusted Computing Base so is itself secure. The digest may be a hash or other unique and representative value.
