摘要:
This device is a balance board used for core exercise, balance training, and training for rotational motion applicable to various board sports. The invention consists of a board or deck upon which the user stands having the shape and contours of a traditional skateboard deck. On the underside of the board are three half spherical fulcrum points fixed at specific locations. The primary fulcrum point is the largest and is located in the center of the board. The additional two fulcrum points are smaller and are located one each at the nose and tail of the board. This orientation allows the user to spin freely on the board on a horizontal axis. Rotational motion is possible on any of the three fulcrum points depending on the user's ability.

A screening module 10 comprises a frame component 12 to be secured to an underlying screen deck, in use. A screening panel 14 is carried by the frame component 12. The screening panel 14 comprises an operatively upper screening surface 16 and a support structure 18 underlying the screening surface 16 with a plurality of spaced protrusions 20 being supported by and standing proud of the support structure 18. Operatively upper ends of the protrusions 20 lie substantially in a plane of the screening surface 16 and the protrusions 20 define a plurality of screening apertures 22 in the screening surface 16.
摘要:
An assembly for extracting heat from a housing for electronic equipment, the housing having a front, a back, two sides and a top. The assembly is defined by a back for the housing that defines an open area proximate the top, and an air passageway in fluid communication with the open area in the back, to conduct heated air exiting the housing through the open area away from the housing.

A screening panel assembly (10) includes a frame (12) on which a screening panel (14) is supported. The frame (12) has frame members and intermediate members with the panel (14) being secured only to the frame members of the frame (12).
摘要:
An assembly for supplying heated air to a housing with an interior that is adapted to hold air conditioning equipment. The housing has a top portion and a back portion, where the top portion defines a first opening that leads to the interior of the housing, and where the first opening is proximate the back of the top portion of the housing. The back portion of the housing defines a second opening that leads to the housing interior, where the second opening is proximate the top of the back portion. The assembly includes a flue external to the housing and adapted to be coupled to the housing such that the flue encompasses and is in fluid communication with the first and second openings, the flue defining an inlet for conducting heated air into the flue and an outlet for conducting heated air out of the flue and into the housing through the first and second openings. The air cooled by the air conditioning equipment in the housing is used to cool electronic equipment.

The invention combines systems and methods for heat containment and cold air isolation for managing airflow and temperature in data centers. The data center contains at least two rows of cabinets containing heat-generating equipment and arranged to form a cold aisle and a hot aisle. The data center system includes panels or doors at both ends of the cold aisle and an optional cover over the cold aisle to inhibit cooled air supplied by an air conditioning system from exiting the cold aisle and inhibit air warmed by the heat-generating components from entering the cold aisle,. A chimney coupled to the top, rear, or top and rear of the cabinets is configured to exhaust the warmed air into a region above the rows of cabinets. The chimneys may be ducted to a plenum or suspended ceiling or to the intake of the air conditioning system. Baffles and/or fans may be included in the chimneys, ducts, and/or plenums to control the air pressure. The invention may also include one or more data center air conditioning units, and each air conditioning unit may be configured to service one or more rows of cabinets. Alternatively, or in addition, cool air may be supplied by the building's air conditioning system.
摘要:
A screening module for a screening assembly includes a substantially rectangular, planar screening member having a plurality of screening apertures extending through it the member having a pair of sides extending parallel to a direction of flow of material over the member and a pair of sides extending transverse to a direction of flow of material over the member. A mounting means is formed integrally with the screening member as a one-piece unit for securing the member to an underlying structure. A part of the mounting means is arranged along each side of the screening member and only the parts of the mounting means associated with one pair of sides having reinforcing with the parts of the mounting means associated with the other pair of sides being without reinforcing.
摘要:
A securing device for securing a screening panel to a support frame of a vibrating screen assembly. The securing device has a body with a securing means at one end and a stub at the lower end. The securing means is shaped to mate with a complementary securing cavity in the screening panel and has a hole that receives a pin located in the securing cavity. The stub may be threaded to engage the support frame.
