WO/2016/167714 FOLDABLE SHIELD||WO||20.10.2016|
||PCT/SE2016/050324||SAINTPRO AB||YAKOUB, Raed Roro|
Foldable shield (100) which can be brought from an extended use position to a folded transport position and vice versa, and comprising shield plates (101, 102, 103) and spring loaded hinge means (104, 105) connecting the shield plates, restraint devices (106, 106', 106") for holding the shield to a user's forearm during use, and a release device (107) for releasing the cooperating locking means (108) so that the hinge devices brings the shield plates from the transport position to the extended use position.

WO/2016/167697 MARINE RADAR SYSTEM||WO||20.10.2016|
||PCT/SE2016/000001||KJELLINGLAND, Tore||KJELLINGLAND, Tore|
The invention refers to a marine navigation radar system, where the need for multiple antennas mounted on a ship is removed by creating a new type of radar antenna where several antenna arrays are stacked on top of each other into one antenna assembly housed in one single radome. The number of antennas in the assembly can be as many as four or even more and the antenna assembly is furthermore gyro stabilized to create a stable and more constantly updated radar picture. An important feature of the invention is the considerably increased update rate of the radar picture. Another important feature of the invention is the possibility to operate the individual antennas in the assembly independently, which will result in one or a few antennas being "locked" on nearby ships, oil-rigs, navigation buoys or reference points.

WO/2016/167708 WAYS TO CLEAN FLUE GAS EMISSIONS IN A SCRUBBER||WO||20.10.2016|
||PCT/SE2016/050308||LKW TEKNIK AB||WAARDAHL, Lars|
A scrubber with one or more tray levels, provided with rocker valve cassettes, cleans marine diesel engine exhaust gases from sulfur oxides and nitrogen oxides, since the back pressure is low and by the invention can be kept constant and within permitted limits, and this over the entire engine RPM - and power-rating register, because these engines are particularly sensitive to high back pressures. The invention can also be applied in similar demanding industrial processes such being sensitive for variations in backpressure or having requirements for 100% SOx purification and/ or NOx purification > 8%. In testing, performed with diesel fuel with increased sulfur content, a 100% efficient sulfur oxide purification has been confirmed as well as a simultaneous NOx purification up to 25% and it was also verified that the exhaust gases can be introduced directly into the scrubber, without clogging problems due to the soot in the exhaust. Further advantages are obtained by that a scrubber of the invention operates at high sulfite content, up to at least 200 g /L, wherein less chemicals and fresh water is spent, whilst the space for holding tanks is reduced. The applications are mainly in the marine sector.
WO/2016/167707 METHODS AND ARRANGEMENTS RELATING TO SENDING INFORMATION REPEATEDLY FROM A SENDING NODE TO A RECEIVING NODE IN A CELL OF A WIRELESS COMMUNICATION NETWORK||WO||20.10.2016|
||PCT/SE2016/050305||TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)||ERIKSSON LÖWENMARK, Stefan|
A sending node (120; 110) sends information to a receiving node (110; 120). Said nodes are comprised in a wireless communication network (100). Communication between said nodes is associated with a first cell (115). The sending node (120; 110) obtains (601; 701) predefined scrambling for scrambling the information and which predefined scrambling is specific for the first cell (115). The receiving node correspondingly obtains de-scrambling. The sending node (120; 110) sends, to the receiving node (110; 120), the information repeatedly a certain number of times, wherein each time the information is sent it is scrambled differently based on the obtained scrambling. Each time the information is received by the receiving node (110; 120) it is de-scrambled differently based on the obtained de-scrambling.
