Granted: 2003-09-09
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use ofthe camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider ispositioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Abstract: Disclosed is a substantially dust free solid like ammonium sulfate that is treated with a blend of water or solvents and distillation bottoms. The distillation bottoms are liquid at about 60°C or less and are obtained from production of an alcohol having the formula:     wherein R1 is substituted or unsubstituted, branched, straight chain, or cyclic C4 to C12 and R2 is OH or H.          The application of such distillation bottoms to the solid hinders the tendency of this solid to generate dust.          Thus the resulting solid materials are substantially dust-free, which make them particularly useful in the solids handling industry, especially in the granular fertilizer field.          Aslo disclosed are treated solids that are in the form of unpaved thoroughfares such as gravel parking lots and dirt roads.

Abstract: A DC-to-AC converting circuit generates an alternating current by alternately switching a set of switching elements. The alternating current is supplied to a load Lo via an output filtering circuit. If a current detection resistor R1 in the DC-to-AC converting circuit detects an output current that exceeds a reference voltage Vref corresponding to an over-current set value, certain switching elements are turned off to disconnect the DC-to-AC converting circuit from the power source. However, the DC-to-AC converting circuit continues to generate an alternating current from energy stored in one or more inductors that are coupled to the DC- to-AC converting circuit. Preferably, a closing circuit is formed from a diode, a switching element, the load Lo and the inductors. Thus, even if the DC-to-AC converting circuit is disconnected from its power source, an alternating current continuously flows to the load Lo.
