Patent number: 10605504Abstract: A ducted separator in a compressor-based cooling assembly is connected to an oil/gas outlet of the compressor. The ducted separator is a pipe with at least one bend in it which collects oil in a manner which can achieve 98% oil carry over efficiency. The ducted separator may optionally be connected to a second phase separator such as a centrifugal cylinder. In that case, the height of the centrifugal cylinder can be significantly reduced compared with conventional arrangements. Alternatively, a simpler impingement surface such as one or more baffles may be used as the second phase separator or just a collection chamber.Type: GrantFiled: October 9, 2014Date of Patent: March 31, 2020Assignee: J&E HALL LIMITEDInventors: Terence William Thomas Young, John Michael Roll

Patent number: 8702408Abstract: A slide for use in a single screw compressor is disclosed. The screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of the slide instead of to the discharge port. The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the disclosed slide further allows the use of an offset discharge port in the casing, in relation to the main rotor.Type: GrantFiled: November 20, 2009Date of Patent: April 22, 2014Assignee: AAF McQuay IncorporatedInventors: Terence William Thomas Young, John Michael Roll, Peter Michael Woodard

Patent number: 8622446Abstract: A bumper for a motor vehicle includes a crossbeam having a hat profile defined by a bottom wall, legs respectively adjoining the bottom wall, and flanges respectively extending from the legs. The hat profile has sections of varying cross sectional configuration in a longitudinal direction. A face plate closes the hat profile to define a hollow space, with the crossbeam being mountable with the face plate such as to point outwards. An upper one of the legs has a width which is greater than a width of a lower one of the legs in a center section of the crossbeam. The crossbeam has curved ends oriented in a direction of the motor vehicle, and the face plate includes in the center section a stiffening embossment which is oriented into the hollow space defined by the hat profile and the face plate.Type: GrantFiled: October 31, 2011Date of Patent: January 7, 2014Assignee: Benteler Automobiltechnik GmbHInventors: Christian Handing, Michael Roll, Ulrich Lüdtke-Bexten, Elmar Mollemeier

Patent number: 8419091Abstract: A bumper for an automobile includes a crossbeam which is formed from at least two separate hollow profiles, wherein the hollow profiles abut one another along a longitudinal wall and are joined with one another. The abutting longitudinal walls form a double web oriented in the longitudinal direction of the automobile. The hollow profiles may have an identical cross-sectional configuration. The hollow profiles may be roll-formed or extruded. The modular construction of the crossbeam from separate hollow profiles allows a lightweight construction and allows the load characteristic of the crossbeam to be functionally adapted to different requirements depending on the vehicle or vehicle class.Type: GrantFiled: December 13, 2011Date of Patent: April 16, 2013Assignee: Benteler Automobiltechnik GmbHInventors: Michael Roll, Christian Handing, Martin Schröter, Andreas Schiller
