Abstract: A slide block for slideably and pivotally mounting a window sash to a side member of a window frame having a vertical window jamb channel. The slide block includes a body, the body defining a sash pivot-receiving aperture. A sash pivot retainer spring is integrally formed with the body and is positionable between a first position obstructing removal of a sash pivot when the sash pivot is disposed in the aperture and a second position permitting removal of the sash pivot.

Abstract: The present invention relates to inertial braking system for spring-loaded devices, such as block and tackle window balances incorporated in single and double hung window assemblies. In one embodiment, a block and tackle window balance includes a translatable block assembly disposed in a track including a pawl pivotally attached to the translatable block assembly. The pawl, in response to a rapid acceleration of the translatable block assembly, rotates about a pivot and frictionally engages the track, thereby wedging the translatable block assembly in the track. In another embodiment, the translatable block assembly includes a cam attached to the pawl and a brake shoe disposed between the cam and a cord seated within a pulley. Rotation of the pawl causes the cam to translate the brake shoe, thereby compressing the cord against the pulley.

Abstract: A temperate water supply is provided. The temperate water supply system includes a temperate water storage tank and a heat exchanger. The temperate water storage tank has a first tank inlet, a first tank outlet, a second tank inlet and a second tank outlet. The first tank inlet is connectable to a cold water source. The first tank outlet is connectable to at least one temperate water use point in the residence. The heat exchanger has a heat exchanger inlet and a heat exchanger outlet and a plurality of water conduits connected in parallel fluid communication with the heat exchanger inlet and with the heat exchanger outlet. The heat exchanger inlet is connectable to the second tank outlet, and the heat exchanger outlet is connectable to the second tank inlet. In use, the plurality of water conduits are filled with water and are in contact with ambient air in the residence that is warmer than the water at least a portion of the time, so that heat is transferred from the ambient air to the water.

Abstract: A business method for providing Internet access to users comprises requesting access to the Internet via the public telephone network or other Internet access infrastructure such as DSL, cable, wireless, or dedicated line, presenting a user name and password and then verifying the user name, password, account activation status and account time balance if the account is for a fixed amount of on line time, or date of expiration if the account is for a fixed elapsed time. The system acknowledges user access by identifying the account time balance or expiration date. This is followed by allowing access to the Internet and using the Internet access for a session time of not more than the account time balance or up to the terminal date. After that the access time is disconnected. A new account time balance is calculated if appropriate and the time balance, if any, is communicated to the user.
