Title: Self-optimizing subcooler control
Inventor: HJORTLAND ANDREW
IPC: F25B40/02
Filed: 2020-01-16
Abstract: According to certain embodiments, a method comprises determining a liquid outlet temperature setpoint for refrigerant discharged from a liquid outlet of a subcooler. The liquid outlet corresponds to a hot-side path of the subcooler that receives refrigerant directly from a tank, cools the refrigerant by an exchange of heat with a cold-side path of the subcooler that receives the refrigerant from the tank via an inlet expansion valve, and discharges the refrigerant to an evaporator via an outlet expansion valve. The method further comprises determining a superheat setpoint for the refrigerant discharged to a compressor via a vapor outlet of the cold-side path.  The superheat setpoint is determined based on the liquid outlet temperature setpoint.  The method further comprises adjusting a temperature of the refrigerant discharged to the compressor based on the superheat setpoint.

Title: Improved steel gondola railcar
Inventor: NELLE GEORGE A
IPC: B61D17/04
Filed: 2020-04-14
Abstract: A gondola car is made of high strength and high abrasion resistance steel that provides a lightweight structure and that prolongs the useful life of the car. The high strength and high abrasion resistance steel enhances the strength of the gondola car without increasing its thickness. The contemplated railcar positions components (e.g., side posts and cross-bearers) of the railcar away from areas of the railcar that experience high stresses during transport. In this manner, these components can be welded to form the railcar, and the welds will experience less stress during transport resulting in less weld breaks. Additionally, the number of components (e.g., side posts and cross-bearers) may be reduced, which reduces the weight of the railcar.
