Abstract:
Apparatus for providing activated treated water to washing machines with a water treatment conduit connected between a water supply and an inlet of the washing machine, having a reactor chamber with a UV lamp and a coated metal target that generates oxidizing gases that communicate by an injector into the conduit and a transparent portion of the conduit treats the oxidated water by illumination from the UV lamp. A disinfector injects disinfecting silver ions into the treated oxidated water. A controller activates the apparatus during flow of water through the conduit. A method of activating and treating water for washing machines is disclosed.
Abstract:
A machine-aided method for selecting roofing systems to match particular building roof design features. Logic branches are employed to guide a machine to the determination of an appropriate roofing system on the basis of design feature data entered by a user. Apparatus for specification generation are also disclosed wherein a roofing specification may be generated which corresponds to the selected roofing system. An illustrative example is also described.
Abstract:
A portable air purifier for purifying air in selected occupied spaces, comprising a base for attaching to a support in the space, a housing pivotally mounted to the base, a fan mounted within the housing and having an air inlet and an air outlet for communicating air through the housing and at least one air treatment device supported in the housing for acting upon air communicated by the fan.
Abstract:
A novel thermosettable composition-of-matter is disclosed. One embodiment of the composition-of-matter includes a polymeric thermosettable ingredient having at least three acetoacetoxy-type functional pendant moieties as well as at least three acid-functional pendant moieties. Another embodiment of the composition-of-matter includes at least two polymeric thermosettable ingredients, one of which includes at least three acid-functional pendant moieties and the other of which includes at least three acetoacetoxy-type functional pendant moieties. The novel composition is characterized in that the acid-functional and acetoacetoxy-type functional pendant moieties crosslinkably-react together, when subjected to elevated-temperature conditions for a predetermined period of time, thereby producing a crosslinked polymeric network. The novel thermosettable composition-of-matter can be used "as is" if either of the polymeric thermosettable components is a "fluid" (i.e., is able to flow) at room temperature. Otherwise, the novel thermosettable composition-of-matter may be formulated into a solvent-borne coating composition, a water-borne coating composition, or a powder coating composition.
Abstract:
A card game simulator simulates a card game by means of a set of hand displays, which may be seen only by one player at a time, and a set of corresponding play displays, which may be seen by all players. Each hand display includes a set of light emitting diodes which are lit to indicate the cards held by the hand simulated by that display. Cards are played by placing a photosensing probe against an activated light emitting diode, which action causes the corresponding play display to indicate the playing of the card corresponding to the light emitting diode sensed by the photosensor. The light emitting diode in the hand display is then de-activated. The invention as disclosed is adapted for simulating a game of bridge, and the circuitry for the simulator includes a recirculating hand memory for cyclic sequential readout of fifty-two hand codes and a recirculating trick memory for cyclic sequential readout of fifty-two trick codes. The two memories recirculate in synchronism, and the output codes correspond respectively to hand assignments and trick assignments for the fifty-two cards in a standard bridge deck. Cards are indicated on the hand displays and play displays in accordance with the hand codes and trick codes read out from the hand memory and the trick memory. Hand codes may be loaded into the hand memory in a random sequence for simulating a standard game of bridge, or they may be loaded in a predetermined sequence from a programming unit for playing duplicate or team bridge.

Abstract:
An air purifier (10) held in a housing (12, 14) with an ambient air inlet (16) and an air outlet (18) and defining an airflow path therethrough for treating ambient air, a filter (disposed in the airflow path and having an air permeable media for communicating air therethrough while retaining particles carried in the flow of air. A purification device attaches to an intermediate chassis in the airflow path for treating the air moved by a fan (70) into operative engagement with the purification device within the housing and out the air outlet. A controller operates the purification device by sensing an operative status of the purification device.
