摘要： The present invention relates primarily to folded fabric products, such as baby wipes, hand wipes, fabric softener sheets, and the like. Folded individual sheets include a visual indicator, such as a line of contrasting color, at the location of the sheet which should be removed first by the user. In a preferred example, folded baby wipes include moistened, non-woven fabric, folded in such a way that the visual indicator is located at the top of each folded sheet. A plurality of sheets can be stacked in a tub or container. Removal of one sheet will present the indicator of the next lower.

摘要： An apparatus for maintaining a predetermined liquid level within a tank while effecting the continuous addition and removal of liquid within the tank. The apparatus is provided with a housing that mounts directly on a side wall of the tank with the housing extending on both sides of the wall, so that it is partially inside and partially outside the tank. The housing has a first passageway which receives fresh liquid from a pressurized supply and introduces a portion of the fresh liquid into the tank. The remainder of the fresh liquid is provided to a second passageway which is connected between the first passageway and a drain. The second passageway has a constriction near its inlet, which accelerates liquid flowing through it and injects the liquid into the second passageway at a high speed. This produces a region of low pressure in the second passageway. A third passageway is connected to the region of low pressure and it is coupled to the water in the tank. By this arrangement, the low pressure is coupled to the third passageway, and is expelled to the drain. In one embodiment, the apparatus includes a mechanism for fail-safe operation in the event of excessive supply pressure build up.

摘要： An interlock circuit is provided for use with machines to prevent starting of the prime mover unless an interlock switch is in a safe condition. In the illustrative embodiment the interlock circuit is adapted to prevent starting of the engine of a lawn tractor unless the clutch thereof is disengaged. After the engine is started the clutch may be engaged without killing the engine. The circuit comprises a controlled rectifier connected across the magneto primary coil through a rectifier. The voltage pulses applied across the output of the controlled rectifier are also applied to the gate thereof through a capacitor in a charging circuit which includes the input of the controlled rectifier. The interlock switch is connected across the input of the controlled rectifier and when it is opened, as by engagement of the clutch, the applied voltage pulses to the input of the controlled rectifier through the charging circuit causes the controlled rectifier to conduct on each pulse. Accordingly the ignition system is disabled and the engine cannot be started. When the interlock switch is closed the input of the controlled rectifier is short circuited and the controlled rectifier cannot be turned on; hence the ignition voltage is unaffected and the engine can be started. After the engine is started the clutch may be engaged and the interlock switch opened without killing the engine because the discharging circuit of the capacitor is altered so that the capacitor does not discharge sufficiently between pulses to take sufficient charging current to turn on the controlled rectifier.

摘要： A protective control circuit is disclosed for vehicle electrical systems such as those used on trucks and military vehicles. Such electrical systems are provided with a reverse polarity relay for connecting the battery to the generator. When the accessory switch is closed to energize the reverse polarity relay a holding circuit is provided for the relay so that the battery remains connected with the generator even after the accessory switch is opened to shut down the engine. The continued connection of the battery with the generator serves to avoid transient overvoltages which would be damaging to electrical components connected in the system. When the engine and hence the generator stops spinning the battery is disconnected from the generator by disabling the holding circuit.

摘要： A method and apparatus for producing liquid impregnated fabric wipes and packaging the wipes in a container. Fabric material in sheet form is initially passed through a folder to fold the side edge of the sheet, and the folded sheet then travels over a pair of liquid impregnating tubes where liquid is discharged from slots in the tubes against opposite faces of the folded sheet material. After impregnation with the liquid, several sheets are placed together in superimposed form and cut into short lengths to form wipes. The wipes are supported along their side edges by two pair of cooperating endless conveyor belts and as the wipes move along the conveyor, a reciprocating platen moves downwardly between the spaced belts to eject the wipes from the belts onto a conveyor or pack the wipes into a container.
