Patent SE-8403389-L (SE)
Inventor: LUDWIGSON P-O
IPC: B63B1/10
Filed: 1984-06-26
Abstract: A semi-submersible vessel has a deck structure (10) supported on columns (11) above two hulls (12) and means to ballast it between a transit condition wherein the hulls have freeboard and an operating condition wherein the hulls and part of the columns are submerged. Two cranes (14) are mounted on the deck above the rear columns (11). A body (19) interconnects the hulls (12) below the rear columns (11), and lies underwater on the vessel's transit condition. The body provides structural strength, extra buoyancy under the cranes, and an increase in the inertia of the vessel in relation to heave and trim motions when the vessel is semi-submerged, and is streamlined to reduce drag in transit. A second body (19) may be provided at the front of the vessel close to a second pair of columns (11). <IMAGE>

Abstract: A control unit (32) governs compressed air supply to a siren, and apart from a valve (41) which alternately taps high pressure containers, has a reduction valve (44), together with a magnet valve (47), controlled by external signals, for transmission of air impulses at reduced pressure to the siren. In the control unit is a pressure monitor (46a) which provides signals if the air pressure is too low. The high pressure container unit and the control are built into a lockable box with an inspection hatch for connection of signal lines (33) coming from outside. A two-way valve (48) is inserted downstream of the magnet valve in the low pressure air line (46), which when the siren is disconnected may conduct compressed air impulses to a noise damper (49). The control signals are transmitted via telephone lines (33), and a control plinth (35) which locks the box contains telephone jacks (36).

Abstract: A connector for producing a compressed air joint between a compressed air main (1) and a line (16) to be joined thereto has a socket (4) that is fixed in a port (2) in the wall of the compressed air main (1). The socket has elastic lips (8) resting against each other to shut off the port (2). A compressed air line to be joined with the socket is inserted into a receiving opening (12) in the sleeve (4) so that the sealing lips (8) are splayed outwards. The sealing lips make close contact with the outer face of the compressed air line and they are moved so far apart that there is a free flow path for the air into the line. On retracting the line (16) from the socket the sealing lips close again as a check valve. <IMAGE>

Abstract: The present invention relates to a tool and a means for the replacement of underground ducts. The tool being in principal self-propelling consists of a breaking part (25) and a pipe connection part (24). The tool is hydraulically operated over hydraulic tubes (7). The breaking part (25) has break segments (1) with stepwise increasing radius and the pipe connection part (24) has a feeding cylinder (14). One or several double pistons (2) are attached to the segments (1) by lifting links (4). Each double piston (2) moves in two cylinders (9, 10), which are so connected that when the pressure acts on the piston rod side in one of the cylinders then the pressure in the other cylinder acts on the side without piston rod and vice versa. The lining with new pipes (16) takes place according to the operating cycle below. The breaking part (25) is first expanded radially outwards, whereby the existing pipe is restored to a circular cross section or is expanded to a larger diameter. Then the feeding cylinder will advance the new pipe (16). At this moment a wire (8) acts as an extra counter force in order to assist the tool, which is expanded against the existing pipe. When the new pipe (16) has been advanced the breaking segments will return, whereby the diameter of the tool is decreased, and then the tool is advanced. This ends the operating cycle and, thus, the next step will be to expand the tool radially.

Title: Detecting particles in medium transparent to some types of radiation - having spread radiation from source limited to lobe determined by detector system lobe
Inventor: LOEFVING STEN
IPC: G01N21/47
Filed: 1991-06-05
Abstract: The radiation source lobe and that of the detector system only overlap one another within a closed and limited area. The output effect from the radiation source is regulated by a regulating system back-coupled by means of radiation where the actual value is obtained as output signals from a monitor detector system achieved by spread light from a surface. Light hits this surface from the radiation source, whereby the regulating system ensures that the measurement system sensitivity is compensated for dirtying of the transparent material in the radiation path. The surface in question spreads diffusely and is placed outside the main detector lobe and longer away from the radiation source than the centre of gravity of the area where the radiation source lobe overlaps that of the detector system.

Abstract: The present invention relates to an optical analyser (2) capable of performing simultaneous measurement in a first test chamber (12) and a second test chamber (22). The analyser (2) has a first radiation path (4) and a second radiation path (18), the first test chamber (12) being placed in the first radiation path (4) and the second test chamber (22) being placed in the second radiation path (18). Radiation in the first radiation path (4) is generated by a first source of radiation (6), and radiation in the second radiation path (18) is generated by a second source of radiation (20). A filter device (18), containing a number of optical filters (10C, G), filters out specific wavelengths which are to pass through the respective test chamber (12, 22). The filter device (8) rotates so the optical filters (10C, G) are alternately placed in the first radiation path (4) and the second radiation path (18) respectively. Radiation passing the first test chamber (12) is registered by a first radiation detector (14), and a detector signal is sent to an analysis unit (16) which identifies or determines the concentration of the specific substance in the first test chamber (12). In the corresponding manner, radiation passing the second test chamber (22) is detected by a second radiation detector (24), which also send the detector signals to the analysis unit (16), so the corresponding analysis of the specific substance in the second test chamber (22) is performed. <IMAGE>
