Publication number: 20230175504Abstract: A vane pump has a rotor and a control slide mounted within an internal chamber of a housing. The rotor has a number of vane mounting openings and vanes. Rotation of the rotor generates a pressure differential between inlet and outlet ports of the pump to draw fluid in and output the fluid out. Both the vane mounting openings and vanes are arranged in pairs that are diametrically opposed to one another with respect to the rotor axis. The vanes in each said pair have an intermediate transfer member extending therebetween that shifts with one vane of each said pair retracting radially inwardly by engagement with the internal surface of the rotor receiving space for extension of the opposing vane of each said pair radially outwardly toward the internal surface of the rotor receiving space. The intermediate transfer member may be a pin provided between the vanes of the pair.Type: ApplicationFiled: December 5, 2022Publication date: June 8, 2023Inventors: Paul MORTON, Luke BOUWMEESTER

Patent number: 11493036Abstract: A variable displacement vane pump is described. The pump includes a control chamber provided between a housing and a control slide. A pressure-controlled relief valve is in fluid communication with the outlet path and moves to block or unblock a relief port based on output pressure of the lubricant. A feedback channel fluidly connects the control chamber to an inlet path of the pump. The feedback channel further connects to a control port that is connected to a main control valve. The relief valve and control valve are distinct and not fluidly connected. The relief valve moves once the pressure in the outlet path exceeds a predetermined amount, opening the relief port, and thus delivers a portion of the output lubricant to the control chamber via the relief port, thereby pressurizing the control chamber and reducing eccentricity of the pump by displacing the control slide.Type: GrantFiled: May 19, 2020Date of Patent: November 8, 2022Assignee: Stackpole International Engineered Products, Ltd.Inventors: Paul Morton, Matthew Tyler Hughes, Theresa Kam Lun Chan, Michael Benjamin Sy

Patent number: 11092871Abstract: A novel transmitter is proposed that provides broadband all-optical linearization of a Mach-Zehnder interferometer (MZI) modulator for use in high linearity RF photonic links and optical up-converter and down-converter schemes. It is based on an amplitude modulated (AM) MZI modulator where part of the laser Carrier is passed around the MZI modulator and added back to the AM signal, creating a Controlled Carrier-AM (CC-AM) signal. In this new scheme, a dual output MZI modulator is utilized, and the alternative output (Carrier*) is used together with the Carrier from the laser to create a new signal, LO*, which when coherently combined with the AM signal can reduce or completely cancel its 3rd order intermodulation distortion.Type: GrantFiled: June 29, 2020Date of Patent: August 17, 2021Assignee: Morton PhotonicsInventors: Paul A.

Patent number: 11005233Abstract: A low noise, single mode laser includes a semiconductor gain element generating light and having a highly reflective first end forming a first end of a laser cavity. The gain element may be monolithically or discretely integrated with, or distinct from, and coupled to a waveguide comprised of a low loss material with a refractive index ānā greater than 3. The waveguide includes a Bragg grating forming the second end of the laser cavity. A cavity phase control section may be provided between the gain element and the Bragg grating. Two photodetector monitors provide a feedback signal for locking the light from the gain element to a specific wavelength on the Bragg grating reflection spectrum by varying at least one of the cavity phase control section and the gain element bias current. The Bragg grating may have a physical length larger than 10 mm and that occupies at least 50% of the optical length of the external cavity.Type: GrantFiled: July 23, 2019Date of Patent: May 11, 2021Assignee: Morton Hybrid Lasers, LLCInventor: Paul A.
