IPC: E21B4/14
Filed: 2001-01-24
Abstract: A pneumatic ground piercing tool 40 has a striker 12 that reciprocates within an internal chamber of an elongated tubular tool housing <B>13</B>. The striker <B>12</B> impacts an anvil <B>46</B> in a front end opening of the tool housing <B>13</B>. The anvil <B>46</B> has a lengthwise bore that has an enlarged diameter rear end portion. A chisel <B>43</B> is slidably disposed in the bore of the anvil <B>46</B> and is movable between a rearmost position at which a rear end portion of the chisel <B>43</B> protrudes from the bore of the anvil <B>46</B> and is struck by the striker <B>12</B>, and a foremost position at which the rear end of the chisel <B>43</B> is forward of the rear surface of the anvil <B>46</B> which allows the anvil <B>46</B> to be struck by the striker <B>12</B>. The chisel <B>43</B> may have a bit <B>18</B> secured to it by pins <B>20</B>, alternatively the bit may be a two piece assembly attached to the chisel <B>43</B> by threaded connections, a rear bit section being tightened against a front bit section in a jam nut fashion. The chisel <B>43</B> has an enlarged diameter rear end portion with a tapering step <B>44</B> that engages a tapering step <B>45</B> in the anvil bore. The striker impact propels the chisel forward until it is stopped by the earth or step <B>44</B> engages step <B>45</B>. Chisel <B>43</B> is returned to its rearmost position as housing <B>13</B> advances towards bit <B>18</B>. Alternatively the chisel <B>43</B> may be biassed into its rearmost position by a spring confined under compression between the chisel <B>43</B> and the anvil <B>46</B>.

Title: Composite high frequency module for dual-band mobile communications device
Inventor: FURUTANI KOJI
IPC: H04B1/40
Filed: 2001-03-12
Abstract: A dual band cellular phone using a single antenna 11, uses a diplexer 13 to directsignals to the two communication band systems, GSM and DCS, as well as respective T/R switches 14a, 14b. Notch filters 15a, 15b remove harmonic distortion in the transmitted signals. In order to control power levels, the prior art systems use a signal representing the transmitted signals extracted by directional couplers in each transmitter output. The invention replaces these by a single directional coupler 16 in the common path between the antenna 11 and the diplexer 13. This reduces the circuit size. The whole module may be implemented by a multi-layer laminated substrate of a material enables further size reduction.

Title: Intruder alarm using remote audio monitoring suitable for a neighbourhood watch scenario.
Inventor: WATSON JOY ANN
IPC: G08B13/16
Filed: 2001-05-24
Abstract: The alarm system comprises one of more transmit modules which pick-up audible sounds at at least a first location to be monitored, and transmit the sounds via radio frequency communications to a receiving monitoring equipment at at least a second location remote from the first. The sounds made by an intruder at the first location are reproduced at the second location by the monitoring equipment, thus raising the alarm of an intruder. If multiple transmit modules are used, they may transmit on separate different frequencies and the monitoring equipment may have multiple inputs so that any transmit module can be heard. A volume threshold may be set below which no sound is reproduced. Indicator lights (see figure 2 and other figures) on the monitoring equipment may indicate which transmit module is picking-up sound.

Title: Terminal and network monitoring and testing in mobile communications systems
Inventor: COOPER DAVID MARTIN
IPC: H04B17/00
Filed: 2002-02-13
Abstract: A method of monitoring the performance of a mobile communications network and/or a terminal using the network in which signals are routed via the network between the terminal and a server, the method comprising analysing signals received by the server relating to the performance of the terminal or network whereby to monitor the operation of the network and/or terminal. System performance may be analysed using any number of the following parameters over time, possibly the duration of a data stream: received signal strength indicator, signal to noise ratio, ratio of energy per bit to noise, ratio of energy per chip to noise, block error rate, frame error rate for voice, measured data rate, location of terminal. System performance may be measured with respect to location. Sampling of the above parameters may be carried out and stored, possibly removably, in the terminal, and transmitted to the server upon a request from the server. Preferably, there is more than one sampling rate that is varied according to the mode of operation, either governed by the terminal or the server. The monitoring of performance may be carried out during a test sequence sent from the server upon request by the terminal, user, user contact centre, or upon abnormal operating conditions. An abrupt deterioration of a measured parameter may be interpreted as a fraud attempt.

Title: A method of controlling a gearbox wherein vehicle direction is taken into account
Inventor: NOACK MARCO
IPC: B60W10/10
Filed: 2002-05-16
Abstract: A method of controlling a vehicle automatic gearbox comprising a gearbox control unit which receives signals from wheel or gearbox output rotation sensors so that a direction of travel of the vehicle is taken into account in order to avoid critical vehicle and/or gearbox conditions such as vehicle stalling. When on an incline the sensors will indicate a backward movement of the vehicle and the control unit may apply brakes and/or increase engine torque, thereby preventing the vehicle rolling backwards and/or vehicle stalling. The control unit may control the vehicle so that it comes to a stop or slows down to a minimal speed or it may prevent a change to a higher gear when a forward gear is engaged. If a reverse gear is engaged a speed threshold may be increased if it is detected that the vehicle rolls backwards. The automated transmission is for off-road vehicles where an engine stall is critical since it deprives a drive of several supporting function, eg power-assisted steering, power brakes etc, after a short period of time.

Title: Method of and Apparatus for Interconnecting Lined Pipes
Inventor: ALLIOT VINCENT
IPC: B23K37/053
Filed: 2002-08-02
Abstract: There are disclosed methods of and apparatus for interconnecting lined metal pipes (18, 20), applying in particular to the offshore oil and gas industry. Corrosion is a common problem in the industry. Lining pipes overcomes the problem, but welding sections of pipe together can be a complicated and time-consuming task, requiring dedicated and sophisticated tooling. More desirable is the ability to use conventional pipe-laying equipment (3, 4, 5, 6, 7, 8, 9, 10) with little additional tooling. As such, there are disclosed methods and apparatus compatible with known offshore connection methods, particularly where the spacing of joints on the pipe is less than 100m. The chosen technique will not significantly impact the laying rate of the lined pipe, compared with unlined pipe. The method includes connecting lined pipes (18, 20) using a corrosion-resistant bridging member (12) that bridges both pipes (18, 20) and is located along its length between the liner (30) and the wall of the pipe, protecting the liners from the effects of welding (80), and further includes expanding rings (50) located within the liners to provide a seal between the liners and the bridging member (12), in a controlled sequence. There is also disclosed a bridging member (12), tooling (70) and pipelay apparatus suitable for use with this method.

Title: Frequency hopping communication device
Inventor: IGARASHI KATSUHITO
IPC: H04B1/7136
Filed: 2003-03-11
Abstract: A frequency hopping communication device has a memory 170 memorizing modulation coefficients related to hopping frequencies of a carrier wave. Whenever a following hopping frequency is decided, a CPU 111 reads out one of the modulation coefficients on the basis of the following hopping frequency from the memory 170 and supplies it to a Gaussian filter 116. The Gaussian filter 116 stores the read out modulation coefficient in a register and multiplies transmission data supplied thereto by the read out modulation coefficient stored in the register to produce a modulation signal. Thus, the modulation signal has voltage amplitude depending on the carrier frequency. A voltage controlled oscillator 131 modulates the carrier wave having the following hopping frequency with the modulation signal from the Gaussian filter 116 and produces a transmission signal which has an approximately uniform frequency deviation regardless of the carrier frequency.
