Abstract: A refrigeration unit includes a cabinet and a first evaporator assembly. The first evaporator assembly is operable between an uninstalled condition and an installed condition. In the uninstalled condition, the first evaporator assembly is not assembled with the cabinet. In the installed condition, the first evaporator assembly is assembled with the cabinet. The first evaporator assembly includes a first evaporator, a first suction line connected to the first evaporator at a first suction line joint, and a first capillary tube connected to the first evaporator at a first capillary tube joint. The first suction line joint and the first capillary tube joint of the first evaporator assembly are leak testable in the uninstalled condition of the first evaporator assembly.

Abstract: The present disclosure relates to a process for production of bis(2-hydroxyethyl) terephthalate (BHET) from polyethylene terephthalate (PET) comprising: (a) effecting partial depolymerization of PET by mixing PET with ethylene glycol in a weight ratio ranging from 1:0.3 to 1:1.5 maintaining temperature of the mixture in a range of 200° C. to 250° C. to obtain a partially depolymerized PET; and (b) effecting depolymerization of the partially depolymerized PET by contacting the partially depolymerized PET with ethylene glycol in a weight ratio of PET:ethylene glycol ranging from 1:1 to 1:4 in presence of a depolymerization catalyst at a temperature ranging from 170° C. to 200° C. for a time period ranging from 2 hours to 5 hours to produce a crude product mixture comprising bis(2-hydroxyethyl) terephthalate (BHET). The present disclosure also provides a process for recycling of PET from PET waste.

Abstract: The present disclosure presents an construction machine having a sand shield comprising: at least one drum mounted to a frame at a side thereof; a drum drive motor mounted to the frame and configured to transmit a driving force to rotate the drum; a stationary shield fixed to surround the outer surface of the drum drive motor; and a rotary shield configured to surround one side of the drum drive plate mounted on the side of the drum and cover a part of the stationary shield so as to receive the driving force from the drum drive motor to rotate the drum, whereby the rotary shield is rotated together with the drum drive plate when the drum drive plate is rotated.
