Abstract: In some aspects, the techniques described herein relate to a refrigerant compressor, including: a shrouded impeller including a passageway permitting refrigerant to flow from a location radially outside a shroud of the shrouded impeller to a location radially inside the shroud.

Abstract: An integrated compressor comprises an electric motor that is prone to windage losses, radial loads, and recirculation flows. According to a first feature, partial grooves or riblets may be formed on the surface of a motor stator that defines the radially outward boundary of the air gap between the motor stator and the motor rotor. These partial grooves or riblets may maintain low to moderate windage losses, while reducing radial loads in the motor. According to a second feature, a support structure may be designed with a nose portion that is configured to disrupt or otherwise reduce recirculation flows within the end-winding cavity housing the end-winding of the motor. According to a third feature, the spiral orientation of the top coil of the end-winding may be aligned with the rotation direction of the motor rotor to reduce recirculation flows within the end-winding cavity.

Abstract: An auxiliary apparatus for E-liquid transportation and injection is disclosed, which includes an installation base, a lower swing disc jig and a mouthpiece tray. Limiting notches are provided respectively at inner sides of two ends of the installation base, an upper end of the limiting notch is connected with an installation side frame, and a bump is fixedly connected with front and rear ends of an upper side of the installation side frame. The lower swing disc jig is connected to a lower end of an inner side of the installation side frame, and an inwardly-concaved groove is provided in a middle of a lower end of the lower swing disc jig.

Abstract: A refrigerant compressor according to an exemplary aspect of the present disclosure includes, among other things, a diffuser including grooves configured to resist backflow of refrigerant. The compressor is used in a heating, ventilation, and air conditioning (HVAC) chiller system, for example.

Abstract: In some aspects, the techniques described herein relate to a refrigerant compressor, including: an impeller; a shaft; a motor configured to rotate the impeller via the shaft, wherein the motor includes a stator and a rotor; and a housing surrounding the motor, wherein the housing includes a first inlet configured to permit fluid to enter the housing and flow along a stator cooling line and a second inlet configured to permit fluid to enter the housing and flow a rotor cooling line, and wherein the first inlet is separate from the second inlet.

Abstract: A processing device receives input representing a selection of a first area of a source image. The processing device sends a request to a server machine for a result image that corresponds to the source image. The processing device, responsive to determining that the server machine does not have the result image, creates a blurred area for the first area, the blurred area corresponding to a portion of the image that contains the first area. The portion of the image having a size that is greater than an aggregate size of the first area and less than the size of the image. The processing device also sends the blurred area to the server machine for storage of the blurred area as the result image. The processing device replaces the first area with the corresponding portion of the blurred area without blurring a remaining area of the image.

Abstract: A processing device receives input representing a selection of a first area of a source image. The processing device identifies a result image that corresponds to the source image. The result image is previously created for the source image using a blur operation. The processing device aligns the selected first area of the source image with a corresponding portion in the result image. The processing device transforms, using the corresponding portion in the result image, the aligned first area in the source image to a blurred area without blurring a remaining area of the source image.

Abstract: A processing device receives input representing a selection of a first area of an image. The processing device determines whether the first selected area of the image corresponds to a blurred area previously created for a second selected area of the image. The blurred area is previously created for the second selected area of the image having a size that is less than a size of the image. The processing device replaces, responsive to determining that the first selected area of the image corresponds to the blurred area previously created for the second selected area of the image, the first selected area of the image with a corresponding portion of the blurred area previously created for the second selected area of the image.
