Inventor: LASSE AMUNDSEN
IPC: G01V11/00
Filed: 2015-10-01
Abstract: A method of generating geophysical data using at least one source, the method comprising generating a geophysical wavefield with a varying signature, using at least one source, wherein the signature is varied in a periodic pattern. The geophysical data bay be transformed into another domain, wherein the domain is such that the data is shifted to a location that is different to the location in the other domain where the data would have been had the varying signature not been used. The data originating from the wavefield may be isolated from any other data that may be present in the other domain. The signature may be varied using a time dither or by varying the polarity.

Title: Tappet, high pressure pump comprising at least one tappet, engine comprising at least one tappet, engine comprising a high pressure pump having at least one
Inventor: David J Lane
IPC: F02M59/02
Filed: 2016-04-01
Abstract: Disclosed is a roller tappet 10 for a fuel pump of an internal combustion engine. The roller tappet comprises a body having a roller reception space 32 that is formed at one end of the body and that is adapted to receive a roller 18. The body further comprises a lubricant supply groove 20 for the reception of lubricant and a tappet alignment groove 28. A first fluid communicating connection 24 is present between the lubricant supply groove 20 and the roller reception space 32 for the supply of lubricant to an outlet 31 that opens into the roller reception space. A second fluid communicating connection 26 is present in the roller tappet that is provided to guide some of the lubricant supplied to the lubricant supply groove 20 to a second point of application, possibly via tappet alignment groove 28, with the second point of application being remote from the outlet 31. The roller tappet provides more lubrication to the roller which is frequently located at the top of an engine and therefore receives less lubricant than other engine parts since gravity forces the lubricant away from the upper engine parts and causes it to pool lower down. The extra lubricant on the roller reduces friction and so reduces wear on the engine parts.

Title: An ION selecting device for identification of ions in gaseous media
Inventor: BORIS ZACHAR GORBUNOV
IPC: G01N27/62
Filed: 2017-03-16
Abstract: A differential mobility analyser (DMA) comprises ion separation chamber 2 and focusing chamber 16. Sample gas containing ions of different ion mobilities enters the focusing chamber from inlet 15 at a predetermined flow rate. A non-uniform charge density on surfaces 17 and 18 creates a non-uniform electric field in focusing zone 14, causing trajectories 19-21 of ions in the sample gas to converge. Ion stream 22 passes through sample gas inlet 30 into the ion separation chamber, in which sheath gas flows from inlet 5 to outlet 11 at a predetermined flow rate. The focusing chamber is at an angle of 30-90° to the sheath gas flow direction. Electrodes 6 and 7 provide an ion-separating electric field across the ion separation chamber, the field strength chosen such that ions of predetermined mobility follow trajectory 22 and are collected at ion outlet 9.

Title: Call center audio redaction process and system
Inventor: Louis Mandic
IPC: H04M3/51
Filed: 2017-08-15
Abstract: The redaction process/system operates on temporarily captured/saved audio file during an agent­ customer-call center (CC) call. Voice-based audio data is captured and processed by monitoring data input from CC-agent into a defined data field (field in a CC-agent-presented form). The redact process generates a start-record time based upon initial data input into the field and further generates an end-of-recording ("EOR") time for the field. The audio file is filtered and segments are permanently saved audio data (A-data) bounded by the start-record and EOR times. Thereafter, all stored audio data is deleted (preferably crypto-shredded) except the saved A-data to substantially eliminate retrieval of initially stored audio data. An IVR process can be used to trigger record ON/OFF instructions. Audio file segments can be trimmed with precursive and successive time periods to move the start and end times of the audio segments. System Operator sets time-trim periods.

Abstract: A feeder system 10 for use in metal casting comprises a feeder sleeve 12 having an open first end (18, figure 1) for mounting on a mould pattern (6, figure 4a), an opposing second end 20 and a sidewall 22 defining a feeder cavity (27, figure 1), wherein a bore 34 extends from the feeder cavity towards the second end of the feeder sleeve, the system further comprising an insert 14 located within the feeder cavity, at least a portion of which extends across an opening 48 of the bore to prevent particles from falling from the bore to the first end of the feeder sleeve. The insert is preferably made of paper or card and may include score lines (44, figure 1) for piercing by a moulding pin (4, figure 4a). The bore may be a blind bore (58) closed by a roof (55). Application of moulding pressure may cause a metal breaker core (76, figure 4b) to collapse and compress, causing the top (4a) of a moulding pin (4) to extend further through the end of the insert and pierce the roof of the feeder sleeve.

Title: Controller area network message authentication
Inventor: JAMES MARTIN LAWLIS
IPC: H04L29/08
Filed: 2017-11-02
Abstract: A method to communicate data via a controller area network (CAN) bus of a vehicle. Data 114 is encrypted along with a freshness value 210 using an encryption key 212. A message authentication code (MAC) algorithm is then applied to generate a MAC 214. Both the MAC and the freshness value are truncated 206 and passed to a message generator 208 which places portions of the truncated MAC 218 and freshness value 216 in separate portions 222/224 of a secured message 106. The receiving device may predict a freshness value based on the truncated freshness value received and a value stored locally. A MAC prediction may be made and a truncated version compared to the truncated MAC received. If the truncated MACs match the message is authentic, if not, the message may be disallowed. The freshness value acts like a salt and may be an incrementing counter value, a timer value or a trip counter value. The encryption algorithm may be AES and the MAC algorithm may be a cryptographic hashing such as keyed-hash MAC or Galois MAC. The truncation scheme may reduce the MAC to a target number of least significant bits based on the criticality of the ECU.

IPC: F04F5/46
Filed: 2017-12-01
Abstract: A fan assembly (1000, fig 1) comprising a motor-driven impeller (1150, fig 4) for creating an airflow and a nozzle comprising a first air outlet 1310. The nozzle 1300 defines a bore 1500 through which air from outside the fan assembly is drawn by any portion of the airflow that is emitted from the first outlet to produce an amplified airflow. The assembly further comprises a second air outlet 1320 arranged so that any portion of the airflow emitted therefrom does not draw air through the bore defined by the nozzle, thereby producing a non-amplified airflow. The second air outlet may be formed on the fan body (1120, fig 1) or on the nozzle and may direct the airflow emitting therefrom so that it divaricates away from a central axis of the bore. A valve 1410a,b may be arranged to direct the airflow to one or both of the air outlets.
