An industrial hopper and support system includes a hopper having a plurality of receivers complementally configured to receive the top ends of legs of a support. The hopper is particularly designed to receive and discharge both solid and liquid material by the mounting of a selected valve, and the receivers include recesses therein which inhibit the spread of the legs and provide a structural connection between the legs of the support when the hopper is mounted thereon. The hopper may be mounted to the legs without the use of tools, but a separate fastener may be used when it is desired to lift both the hopper and its support from above. The support is provided with openings through primary tubular members which align with crossmembers so that forks inserted into the openings pass longitudinally through the crossmembers.

A microwave antenna radome used for covering a microwave antenna and of rotatablely symmetrical includes the following components all of which are arranged concentrically; a compensation portion located at a central portion of the radome and used for compensating phase delay of electrical field at the central portion of an antenna aperture plane caused by blocking of a feed; a main reflective portion located on a periphery of the compensation portion and used for reflecting electromagnetic wave originating from the feed of the microwave antenna at a specific direction biased from the feed; and an auxiliary reflective portion located on a periphery of the main reflective portion and used for bunching and reflecting diffraction electromagnetic wave at edge of the microwave antenna. All components of the radome are specifically shaped. The microwave antenna thus formed has good electrical performance, stable structure and low cost.

The invention discloses a high-power five-cylinder plunger pump. The plunger pump comprises a power end assembly, a hydraulic end assembly and a reduction gearbox assembly, wherein the power end assembly comprises a crankshaft box body, a crosshead box body and a spacer frame; the crankshaft box body, the crosshead box body and the spacer frame are sequentially connected; the hydraulic end assembly is fixed on the spacer frame; the reduction gearbox assembly is fixed on the crankshaft box body; and the cylinder spacing of the five-cylinder plunger pump is 13-14 inches, so that a guarantee is provided for the output of high power of the five-cylinder plunger pump. According to the high-power five-cylinder plunger pump, the problems that the area of a shale gas fracturing well site is narrowand the number of required fracturing equipment is relatively large are effectively solved, thus reducing the use of equipment, and facilitating the arrangement of the well site.

A golf club head includes a golf club head body, a striking plate mounted to a front side of the golf club head body, and a perimeter wall extending rearward along a perimeter of the golf club head body. At least one hole is defined in a toe of the perimeter wall to reduce the weight of the upper part of the golf club head body, thereby shifting the center of gravity of the golf club head downward toward the heel and thereby increasing the inertial moment of the golf club head.

Integrated glass ceramic spacecraft include a plurality of glass ceramic components including molded, tempered, annealed, and patterned glass ceramic components coupled together for forming a support structure or frame or housing through which is communicated optical signals through an optical communications grid and electrical signals through an electrical communications grid, with the optical communications grid and electrical communication grid forming a composite electrooptical communications grid for spacecraft wide intercommunications. The support structure multifunctions as a frame, a housing, a support, a thermal control system, and as part of an electrooptical communications grid while encapsulating a plurality of optical, electronic, electrical, and MEMS devices between which is communicated the electrical and optical signals over the electrooptical communication grid.

A golf club head with strength-enhanced rear body comprises a front body, a rear body and at least one supporting member. The front body comprises a face and a plurality of abutting edges. The rear body comprises a crown, a ribbon and a plurality of abutting edges, with the rear body being made of a nonmetal material having a specific gravity lower than that of the front body, and the abutting edges of the rear body being corresponding to and connecting with those of the front body. The at least one supporting member being made of a light alloy is disposed along a border between the crown and the ribbon of the rear body.

A merchandising display shelf track device for receiving a row of articles for sliding movement therealong has non-planar front face members connected to a base wall and sidewalls. Racking forces exerted on the front face members are transferred through the non-planar face members to the base wall and sidewalls to minimize racking. An anti-torsion bar connects the front face members to prevent spreading of the sidewalls and thereby minimize racking.

A container is provided which includes a top portion having an opening and a side wall extending from the top portion to an end portion of the side wall. A bottom portion is connected with the end portion of the side wall such that the top portion, the side wall and the bottom portion define an interior space of the container. At least one groove is formed in the side wall. The at least one groove includes a central arc portion and end arc portions. The central arc portion is substantially concave relative to a longitudinal axis of the container. The end arc portions are substantially convex relative to the longitudinal axis of the container. The end arc portions are formed adjacent ends of the central arc portion and communicate with an outer surface of the side wall. Desirably, the at least one groove includes a plurality of grooves. The plurality of grooves may be disposed within the rows in an interrupted configuration such that at least a portion of the outer surface is disposed between the plurality of grooves. The central arc portion and the end arc portion may be cooperatively formed to create a load stress path communicating with the outer surface of the side wall for a load applied to the container. In an alternative embodiment, the at least one groove defines a cross-sectional configuration having groove walls extending inward from the outer surface to a groove floor. The groove walls are oriented at a wall angle measured from the outer surface.

A connector is provided to connect a structural rib of a structure to another rib or portion of the structure, such as an umbrella. The connector comprises first and second ends, and can include a reinforcing rib and / or a closure member. The second end comprises at least one recess extending from a side of the connector. The recess can comprise an open end configured to be coupled to a mounting member of an umbrella hub or rib and a closed end configured to rest on or retain the mounting member. The reinforcing rib can extend between the first and second ends of the connector to enhance its strength. The closure member, if present, can be biased to allow or restrict access to the open end of the recess to retain the mounting member in the closed ends thereof.
