Abstract:
An apparatus (10) for creating a use solution of a concentrate diluted, with a dilution rate of not more than 1:130, into a diluent (12) flowing under pressure in a line (22). A normally-closed, user activatable valve (18) is operatively coupled in the line allowing the diluent to flow in the line upon user activation. A flow regulator (26) is operatively coupled in the line downstream of the valve (18), configured to maintain a constant flow rate for the diluent in the line. A constant flow rate pump (32) having an inlet and an outlet is operatively coupled to the valve (18). The inlet is adapted to be operatively fluidly coupled to the concentrate (28). The outlet is fluidly coupled to the line downstream of the flow regulator (26).
Abstract:
A dispenser (10) uses first and second flow controls (70, 73). The flow controls maintain first and second flow ranges independent of diluent pressure within a pressure range, wherein the use solution's concentration is maintained over the pressure range. A third flow control (75) may also be utilized in a third diluent passageway for maintaining a third flow range independent of the diluent pressure within the pressure range. A bypass valve assembly (41) is operatively connected to the third incoming diluent passageway. The bypass valve has a temperature control valve. The temperature control valve having a bypass passageway, wherein additional diluent is added to the use solution, thereby controlling the use solution's concentration.
Abstract:
A support for an outdoor sign has an upright where an upper and lower extent are swingably connected to move between an erect position for use and a collapsed position for storage. A crossbar is pivotally connected to the upright for movement between a perpendicular relation to the upright, for use and a collapsed position for storage.
Abstract:
An apparatus for controlling on site generation and mixing of a two or more part chemistry, such as a peroxide source and a catalyst. In particular, the invention discloses an apparatus and dispensing method for separating solid surfaces that undergo an uncontrolled, continuous reaction when contacted with water and allows for delivery of solid reactive chemistries at the same time in a standard spray from the bottom dispensing configuration while preventing continued reaction after the dosing is complete.
Abstract:
Methods of dispensing an ingredient and measuring an amount of the ingredient dispensed, e.g., at a customer's location usually as the ingredient is used by the customer, in order to improve the dispensing process by adjusting future dispense cycles, accurately dispensing the ingredient, predicting an amount of ingredient to be dispensed.

Abstract:
A sign support stake may be combined with a jack for extraction of the stake. The sign support stake may also provide a heater to melt frozen earth. The sign support can be provided with releasable attachment means to the support to avoid removal by vandals and may be provided with level indicating means to assist achieving vertical orientation for a driven stake.
