Abstract: Butterfly-type wringer mops each include a mop handle having an elongated direction, a receiver immovably coupled to one longitudinal end of the handle and a mop head pivotally attached to the receiver The mop head includes a central member pivotally mounted to the receiver. First and second paddles are pivotally coupled with opposing lateral sides of the central member. The central member and paddles can receive and support an elongated absorbent element. The mop further includes a wringer having one end pivotally coupled to one of the receiver and the central member so as to pivot between a retracted position and an extended position. The wringer includes a pair of spaced apart arms which deflect the paddles from initial positions generally coplanar with one another and transverse to the elongated direction of the mop handle to rotated positions generally side by side parallel to one another as the wringer moves between retracted and extended positions.

Abstract: A wringer mop has a mop head housing, an elongated mop cartridge having an absorbent pad and a tubular mop handle. A pivot couples the mop head housing to the mop handle for pivotal movement therebetween. One or more pairs of spaced-apart wringer rollers are supported by the mop housing on either side of the mop cartridge to secure the mop cartridge within the mop head housing. An actuator mechanism includes a crank in the form of a linkage rod movably disposed within the tubular mop handle. A hooked end of the linkage rod extends within the mop housing into releasable pivotal engagement with the mop cartridge. The mop cartridge includes an tab having an opening therethrough which pivotally receives the hook. The actuator mechanism further includes a crank handle reversibly shiftable between first and second positions to pass the absorbent pad between the wringer rollers.

Abstract: Field emission spraying of liquified metals is obtained using an electrically heated face plate in contact with the metal to be sprayed with nozzles formed in the face plate. The face plate is wettable by, but insoluble in, the metal to be sprayed and is maintained at a temperature in excess of the melting point of the metal to be sprayed by passing an electric current therethrough.

Abstract: An abrasive scrubbing pad device combined with a wringer mop in which the scrubbing pad when not in use is automatically placed in a physical position which does not interfere with the normal mop function of the mop by an automatic pivoting action brought into operation by actuation of the crank handle of the wringer mop. When the crank handle of the wringer mop is moved to the position where the mop head is functional for mopping purposes, the scrubber pad is pivoted out of the way, and when the actuating handle is operated to retract the mop head between the wringer rollers during a squeeze-out operation, the scrubber pad is pivoted into its operating position. The scrubber pad may be incorporated into the mop when originally asssembled or may be added to the mop at a later time. The scrubber pad structure is formed so that the scrubber pad itself may be replaced in the support structure when the pad has been rendered no longer useful by virtue of wear.
