Title: Solids washing in oil and/or gas production
Inventor: Jørgen Bruntveit
IPC: E21B43/34
Filed: 2016-05-05
Abstract: A method of washing oil-coated solid particles such as sand to remove the oil, comprising the steps of (i) providing a vessel 102 having a lower, sand 106 collecting part and an upper part with an exit 112 for liquids, (ii) feeding oil-coated particles therein, (iii) injecting pressurised steam and/or water into the bed of sand through nozzles 108 to agitate the sand particles and remove the oil therefrom, whereby an oil-water mixture is formed above the bed, and (iv) supplying a fluidising liquid to the bed to facilitate delivery of the sand particles out of the vessel. The apparatus for implementing the method further has a system with an oil content sensor 126 connected to the outlet 122 of the fluidising flushing unit 118, which determines via a controller 105 whether the washed sand is sufficiently clean to be disposed of safely or needs to be returned to the vessel via a recirculation pump 127. A device for weighing the sand inside the vessel may be present, preferably incorporated into a vessel supporting frame 104. An array of solid particle filters 113-115 is preferably provided before the exit of the separated oil-water mixture from the top of the vessel.

Title: Material handling apparatus
Inventor: PAUL MARKS
IPC: B66F11/04
Filed: 2016-08-24
Abstract: The material handling apparatus has a support frame (fig.3A,21), suitable for carrying a service module (fig.2) to be placed in a building, with a bracket 22 secured to it, configured to connect to a connection mounting 23; the support frame can be rotated or reoriented from a first position (fig.3C), relative to the connection mounting, to a second position (fig.4C) perpendicular to the first. Preferably, the frame moves from a vertical to a horizontal orientation facilitated by a mechanical linear actuator 34 with a lead screw 31 attached to a sliding arm 40 pivotably attached to the bracket; when in the second position further lateral movement in the range of 0.01-10cm can be performed to facilitate alignment of fixtures on the service module. Alternatively, an actuator with a telescopic arm (fig.5B,53) pivotably attached to the bracket may be used if lateral movement is not required. The frame may have arms (fig.3A,214) in the form of pegs or forks to facilitate holding or carrying the service module and be rectangular or I-shaped.

Title: Wireless communication method using a chaotic signal
Inventor: Celso Greborgi
IPC: H04L27/00
Filed: 2015-05-13
Abstract: The present invention concerns a wireless communication method wherein data to be transmitted is in binary format. The method converts the data to be transmitted into a bipolar binary sequence and applies a compensating code to the bipolar binary sequence to form a compensated sequence. The compensated sequence is then converted into an impulse control series; A chaotic signal to be transmitted can then be generated by using pulse control to apply the impulse control series in a chaotic nonlinear system that has an attractor with a special return map. A return map can be constructed from the received signal and the data can be recovered from the received signal using the point position in the return map.

Title: Urinal Device
Inventor: JAMES HARRIS
IPC: E03D13/00
Filed: 2016-12-09
Abstract: A urinal waste outlet cap comprises a cover portion defining a cavity 3 for locating a cleaning compound/bacterial block 4. A plurality of stems 5 extend from the underside of the cap for fitting inside the waste outlet 7. The cover portion includes a plurality of apertures 2 such that fluid passes across the block, dosing cleaning compound into the outlet. The block is activated exclusively by urine without the need for flushing. The block may sit sufficiently above the water line 8 so that release of the block's bacterial culture only takes place when urine passes through the apertures, thus allowing for waterless operation. Water released in the event of flushing or cleaning passes under the cap without coming into contact with the block. The stems may be flexible and resilient such that they can be urged into the waste outlet. At least one of the stems may comprise an arcuate outer section. The cap may include a connecting section for linking the stems to the cover portion, and the connecting section may be integral with the stems. The apertures may be elongate or circular.

Inventor: Martin Trenk
IPC: B23P6/04
Filed: 2017-02-07
Abstract: A method of repairing a grinding part, such as a roller 10, used in a roller mill is disclosed and comprises a method that includes measuring a grinding part 16 to be repaired compared to predetermined dimensions 18, using these measurements to map material loss 20, and then adding material to build the grinding part to the predetermined dimensions and varying the wear resistance characteristics of the added material depending on the mapped material loss. An embodiment of this also includes a repaired grinding part comprising a base portion comprising an unrepaired grinding part, and adding material coating to the base portion to create a repaired grinding part to meet the predetermined dimensions wherein the added material has varied wear characteristics depending on material loss mapped across the unrepaired grinding part. Wear resistance is varied and achieved by using materials of different wear resistance on at least the outermost portion of the repaired grinding part. Material having the greatest wear resistance will be located where the greatest material loss is mapped.

Title: Autonomous vehicle headlight deactivation
Inventor: AED M DUDAR
IPC: B60Q1/14
Filed: 2017-07-31
Abstract: A system and method for controlling the headlights of a vehicle when it is operating in an autonomous mode. The system includes an autonomous driving sensor (115, fig. 2) programmed to output an object detection signal representing an object near a host vehicle (step 425), and a processor (135, fig. 2) programmed to output a headlight activation signal to activate vehicle headlights (step 435) in response to receiving the object detection signal. The method includes the step 405 of determining whether the vehicle is in an autonomous mode rather than controlled manually. The headlights may also be deactivated or dimmed (step 415) in order to conserve energy when no objects are detected nearby, depending on the location of the vehicle and/or visibility conditions. The object, e.g. another vehicle, a pedestrian, cyclist or animal, may be detected by LIDAR, RADAR, ultrasound and/or cameras. The presence of a nearby vehicle may also be detected via a vehicle to vehicle wireless communication interface, e.g. dedicated short-range communication (DSRC).
