Title: Power regulation during deflection system start up and shut down
Inventor: MEINERTZ FRIEDRICH
IPC: H04N3/18
Filed: 1990-12-19
Abstract: An energy storage device, for example a large value capacitor (C121), is coupled to the voltage supply input terminal (pin 11) for energizing the oscillator circuit for a period of time after the horizontal deflection system is deactivated. The capacitor C121 and a resistor RP06 form a timing network for the first oscillator circuit. The oscillator circuit continues generating synchronizing trigger pulses to, and prevents free-running operation of, a second oscillator circuit (TP01, TP02, Fig 1) that drives the horizontal output stage. A quick charging path for the energy storage device, for example a Zener diode DP47 in parallel with the resistor RP06, minimizes operating time of the second oscillator circuit at the free running rate prior to the initiation of the synchronizing trigger pulses when the power supply and horizontal deflection system is activated. Thus suitable power levels are supplied during system start up and shut down. Overcurrent protection for the output stage during normal operation is provided (TP08, Fig 1). <IMAGE>

Title: Breakwaters
Inventor: STANSBY PETER
IPC: E02B3/06
Filed: 1991-07-18
Abstract: A structure for defence from the sea comprises a breakwater or harbour wall 14 which is exposed to wave action at least at high tide on a beach 20 subject to alongshore sediment transport A, said breakwater 20 having an extent in the direction of said sediment transport. The structure further comprises at least one groyne 30 extending seawards of the breakwater with the breakwater extending upstream of the groyne relative to direction of sediment transport. The beach level seawards of the breakwater and upstream of the groyne is thereby maintainable at a higher level than would otherwise be the case, thereby reducing incident wave height at the breakwater and accordingly reducing the structural requirements of said breakwater. Each groyne may be submerged. Breakwater 14 and each groyne may be of any known construction, e.g. a stone-stabilised rubble mound (Fig. 2). A groyne may be placed first to build sediment on which the breakwater is built. A groyne may extend for similar purposes from a sea wall (Fig. 3). <IMAGE>

The cover 16 consists of a pair of U-shaped clamping elements 28, 30 with legs 36, 38 received within the apertures 34, 32. Each clamping element 28, 30 bridges a respective control pedal 64, 66 and traps it against a respective support plate 52, 48. A key may be inserted in a lock barrel and rotated clockwise to release the ratchet mechanisms. The device is installed by placing the foot 12 against the floorpan, raising the cover 16 and hence the support 14 until the support 14 is positioned just beneath the control pedals, then depressing the cover 16 to trap the control pedals between the cover 16 and the support 14. <IMAGE>

Title: Tool for generating down hole axial force
Inventor: PATERSON PETER DOUGLAS
IPC: E21B34/06
Filed: 1994-10-07
Abstract: A down hole drilling tool which uses the harmonic oscillation of transient pressure waves in the mud within the drillstring, to generate axial force. The invention is particularly suited to extended reach drilling applications where drillstring drag in horizontal sections presents problems when trying to maintain weight on bit. With reference to Fig 1, the tool, being a pipe system, is bounded by an exciter valve 2 at the downstream end and a check valve 5 at the upstream end. The exciter valve 2 is oscillated at one of the critical frequencies of the pipe system in order to establish a resonant condition (water hammer) in the tool. An oscillating standing wave of considerable magnitude is generated, the peaks of which occur at the closed valves 2 and 5. The pressure acting at the closed valves 2 and 5 is transmitted as an axial force to the attached drillstring 1 and 6. <IMAGE>

Patent GB-2290047-A (GB)
Title: Method and installation for laying a pipe-line
Inventor: WOLBERS DICK RIENTS
IPC: F16L58/18
Filed: 1995-06-05
Abstract: The invention relates to a method for laying a pipeline, wherein pipes are welded-to each other along a ring weld 3 and wherein the ring weld 3 is covered with a mastic ring 6. In the known method of this type the mastic of asphalt bitumen is melted and cast into a mould arranged round the ring weld 3. Working with a hot substance (180 DEG C) is dangerous. The vapours from melted asphalt bitumen create an unpleasant and unhealthy work climate. The quality of asphalt bitumen deteriorates the more melted it becomes. In order that the above stated and/or other drawbacks occur neither at least to a lesser extent or not at all the method according to the invention has the feature that the mastic is arranged substantially in plastic condition round the ring weld 3. A mastic press 14 forms a strip 8 of plastic mastic which is clamped around weld 3 by a plurality of movable ring pieces 31. Clamping may be achieved, alternatively, by a ring press 9. <IMAGE>

Title: Force transducer
Inventor: DUNNING KENNETH
IPC: G01L1/14
Filed: 1995-06-07
Abstract: A low profile capacitive transducer 25 is suitable for inconspicuous mounting on a vehicle brake pedal to measure the relatively low force applied to initially depress the pedal whilst withstanding a much higher force which may be applied when the pedal is fully depressed. It comprises a pair of rigid platens 26, 27 spaced apart by resilient folded pins 33, 34 extending about a pair of electrodes 40, 41 carried one each by proximal faces 28, 29 of the platens. The electrodes are separated by a solid dielectric sheet 42 and a small air gap 43. The platens are biased together and against the spacer pins by generally C-shaped preload spring clips 51, 52 extending across the platen edges and bearing on the distal faces at shoulder regions 48', 49'. The peripheral regions of the device may be potted in silicone rubber. The transducer can contract resiliently under relatively low applied force until the air gap is eliminated and thereafter transmit high forces directly between electrodes without the spacer pins being deformed beyond elastic limits. A circuit for producing a capacitance-related signal and having the sensor capacitance in a negative feedback loop of an integrating amplifier (65, Fig.4) is described.
