摘要:
A method for playing basketball in a court having first and second sidelines and a basket located at each opposed end of the court on a long axis of the rectangle includes providing a reduced court with third and fourth sidelines within the first and second sidelines, and a central line (fifth line) along a length of the court, wherein the third and fourth sidelines define an area between 70% to 80% of a regular court; and selectively playing a first game type based on the central line with two classes of players with between 4 and 16 players or playing a second game type inside the third and fourth sidelines with 8 or less players.
摘要:
A basketball court with narrower sidelines (11) yet abiding by the conventional rules of basketball as well as the other boundaries including rim height ten feet, foul line (16) at fifteen feet from the basket and half court line (12). The new boundary resembles the lines for singles matches (21) on a tennis court.

Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.
摘要:
The invention provides a column comprising a hinge assembly, the hinge assembly comprising an upper portion (2) pivotally attached to a lower portion (1) for movement about a first pivot axis (5), the upper portion of the hinge assembly being associated with an upper part (12) of the column and the lower portion of the hinge assembly being associated with a lower part (11) of the column, wherein in use, movement of the upper and lower hinge assembly portions about the first pivot axis from a normal position, in which the upper part of the column is relatively upright, causes the upper part of the column to rotate towards the lower part of the column, thereby allowing the upper part the column to be moved to a maintenance position, a connecting means links (3), via second (6) and third (7) pivot axes, the upper and lower portions of the hinge assembly, and the connecting means is associated with a bias means (9) that exerts a force via the connecting means, which urges the upper and lower hinge assembly portions towards the normal position.
摘要:
The invention provides a microporous material which comprises a positively charged framework and can be utilized as an anion exchange material, typically in the treatment of waste materials in effluent streams, for example in the nuclear power industry. The microporous material facilitates the removal of undesirable anion species from solutions. One embodiment can include a silicophosphate comprising tetrahedra of PO4+ and SiO4. A method for the synthesis of a silicophosphate using a two-phase system which includes an organic phase comprising an organosilicon compound and an aqueous phase comprising a phosphoric acid is also provided.

摘要:
A sports videogame generates and displays a playing area having user customized upgrade features as a reward for a user's gameplay of the videogame. The user earns user customized upgrade features by engaging in gameplay in different gameplay modes or satisfying gameplay performance goals. The user may earn the option of playing a game using the playing area having the user customized upgrade features after a predetermined percentage of the available upgrades to the playing area is earned.
摘要:
A high integrity electrical connector (10) including an electrically conductive retention clip (12) and an electrically conductive internal contact (14). The retention clip (12) includes a substantially tubular wall (16) presenting a longitudinally extending channel (18) and first and second opposed ends (20,22), the wall defining a window (24) intermediate the ends (20,22) and presenting first and second legs (32,34) extending into the channel (18). The internal contact (14) is received in the channel (18) and retained by the first and second legs (32,34) against longitudinal shifting in the channel (18). Lead wires (58,60) having respective terminals (62,64), when inserted into the channel (18) are retained by tines (40,42) which project into the channel (18) and engage circumscribing bands (68) on the terminals (62,64) to resist separation of the wires from the connector (10) and provide a high integrity splice capable of separation when desired by using a standard extraction/separation tool. The retention clip (12) thereby provides an integral, single element capable of conducting current between spliced wires and retaining them against undesired separation.
摘要:
A circuit breaker configured to be remotely operated is disclosed. The circuit breaker includes a set of main contacts configured to connect between an electrical source and an electrical load, an operating mechanism in operable communication to open and close the main contacts, and a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism. The drive system includes a motor responsive to first and second control signals, a primary drive responsive to the motor, and an opening spring responsive to the primary drive, the main contacts being responsive to the opening spring. In response to the first control signal, the primary drive moves to charge the opening spring, and in response to the second control signal and the main contacts being closed, the primary drive moves to allow the opening spring to discharge thereby resulting in the main contacts opening independent of the motor.
摘要:
A coffee table with the added capacity to store daily newspapers after they have been read until they are bailed for recycling. The table is constructed with a drawer 15 divided into sections 16 which are sized to hold respective stacks of daily newspapers. The drawer sections 16 have bailing guides 29 attached to opposite section walls 28 to facilitate bailing of the newspaper.
