Patent GB-2112066-A (GB)
Title: Electronic ignition system for internal combustion engines
Inventor: MACKIE RONALD D
IPC: F02P9/00
Filed: 1982-07-02
Abstract: An electronic ignition system for an internal combustion engine. In a first embodiment an input pulse is generated by a pick up (10) at the same point in each revolution of the engine. Clock pulses at a first pulse rate are counted in an up counter (22) between consecutive input pulses. The resulting count signal is transferred to a down counter (30) which, between the consecutive input pulses, counts down at a faster rate. For an eight cylinder engine this faster rate is four times the first pulse rate, for a six cylinder engine it is three times the first pulse rate, and for a four cylinder engine it is twice the first pulse rate. In a second embodiment a computed count signal is preset into a down counter which is then counted down. In each embodiment, when the down counter reaches its zero count level the count signal is againt preset into it so that it recycles. Each time the down counter passes a preselected count level, an output pulse is generated. Four output lines are provided for use with an eight cylinder engine, three output lines for a six cylinder engine, and two for a four cylinder engine. The output pulses are applied to each output line in turn. Thus, during each engine revolution each output line receives a pulse, and during two engine revolutions each cylinder of the engine receives a pulse. In the event of operation at excessively high speed, only one out of a pre-selected number of pulses is applied and the pulses are sequenced among the output lines to prevent fouling of sparkplugs while inhibiting the excessively high speed operation.

Title: Pontoons
Inventor: WRIGHT JOHN WILLIAM RANDALL
IPC: B63B35/38
Filed: 1983-03-16
Abstract: A pontoon section for a multiple section unit, formed from heavy angle beams (11, 12, 15) at the corners of the section with metal plates (24) extending between the inner edges of the beams and welded thereto along the edges of the plates so any damage received by the section is remote from welded joints. Fittings then may be welded to the angle beams which previously were welded to the plates, thus again reducing the stresses in welded joints. <IMAGE>

Title: A method of, and an apparatus for surveying a region of soil to which a stabilising chemical has been added
Inventor: SUZUKI TAKEO
IPC: E02D3/12
Filed: 1983-03-24
Abstract: In a soil grouting agent injection region surveying method for use in surveying the grouting agent injection region in a soil stabilisation process at least two electrodes are arranged in the area to be surveyed and the resistance of the soil therebetween measured. In the arrangement shown rods (Q,R) carrying electrodes (1 to 8) are positioned in the soil spaced from a chemical grouting opening carrying an electrode P. A potential is applied between the electrodes and changes in the resistance determined to obtain the extent of stabilisation of the soil. A chemical grouting pipe assembly including a swivel joint may be provided with an electrode. Alternatively two earth augers can carry the electrodes. <IMAGE>
Patent GB-2140508-A (GB)
Title: Wind turbines
Inventor: BROWN ALLAN WILLIAM
IPC: F03D7/02
Filed: 1983-05-25
Abstract: The wind turbine has the tips 14 of the blades pivotable to a position 15 in which they act as brakes to slow the turbine down. The pivoting is caused by relative axial movement of the tip 14 and main blade portions 12 under the action of a spring, the latter being normally overcome by a hydraulic actuator 16. When the hydraulic pressure exceeds a threshold valve corresponding to a desired rotational speed limit of the turbine, a pressure switch causes a release valve to dump the fluid pressure in the hydraulic actuator 16, thus allowing the spring to operate and pivot the tip. <IMAGE>

Patent GB-2172110-A (GB)
Title: Electrical testing device for soils
Inventor: JACKSON JACOB
IPC: G01N33/24
Filed: 1985-03-04
Abstract: A meter for determining in situ the dissolved electrolyte content of soils consists of a bimetallic probe connected through a switch to a current meter. The meter is based on a concept embodied in the US Bureau of Soils' cup, but the conductivity determination is made on soil saturated in situ rather than in a conductivity cell, and the conventional AC procedure is replaced by one using DC, the voltage being generated by the dissimilar metals of the electrodes. Both electrodes are tapered in the direction of entry into the soil to ensure good contact, creating a well-defined cell constant independent of immersion depth. since the stem does not pass current.   The switch enables the user to place the electrode-pair in the desired test position before current is allowed to flow, and its magnitude is observed before any, possibly rapid, fall due to electrode polarisation.

Title: Flow imaging by means of nuclear magnetic resonance
Inventor: WEDEEN VAN J
IPC: G01R33/563
Filed: 1985-08-12
Abstract: To form an image (velocity profile) of fluid flowing in a vessel, the fluid is stimulated to produce a time-dependent magnetic resonance signal which is subjected to Fourier- transform. The stimulating is done so as to introduce spatially-dependent phase information indicative of the velocity profile of the fluid. Thus in Fig. 5, for measuring velocity in the x-direction within a z- slice, after selective oxidation of the slice, a long gradient bx (1) is applied, followed by a  pi  pulse. A second frequency dispersing bx gradient bx (2) is present in a period embracing the echo signal, following a phase encoding gradient by (1). Slice section may be omitted for projection imaging, and an image of fluid flow can be obtained by generating two data sets encoded with phase information indicative of two different velocity profiles of the fluid (taken at different times), combining the data sets, and displaying the resulting data set as an image. By analysing the signal over a period not centred at the middle of the echo signal, a frequency offset is introduced giving the image a striped appearance, the strips being curved in the presence of fluid flow. <IMAGE>

Title: Air streamer work unit
Inventor: SMITH W J
IPC: B08B15/02
Filed: 1986-09-27
Abstract: A demountable enclosure is provided in which asbestos related materials or other dusty works can be safely removed from ceilings, walls, or floors, without external contamination. The demountable enclosure can be raised by means of adjustable legs on four corners, each leg adapted to include castor type wheels for ease of mobility and extension of the work areas. Attached to one end of the enclosure is mounted an extract fan unit the duty of which will maintain an air stream effect across the area to be worked. A suitable filter system forms an integral part of the fan unit to ensure adequate filtration from the enclosure. Within the enclosure is mounted a shower rose and shower base to enable the internal dust concentration to be kept to minimal - a shower waste connection with filter and a water connection for the shower rose penetrate through the skin of the enclosure. A specific filter assembly is located between the fan unit and the main enclosure of which the filter units are withdrawable from within the enclosure for replacement. Whilst withdrawal of filters are in progress a special sized filter pack is inserted to protect external areas from contamination. The filter assembly is monitored from "clogging up" by means of a manometer alarm unit positioned to determine high differential air pressures. An adaption for working on smaller areas is disclosed. <IMAGE>
