The pad can be of a relatively abrasive material for scrubbing or can be of a buffer/polisher material. The legs of the clip releasably fasten onto opposite sides of the sponge. The attachment (when used as a scrubber) and sponge can both be squeezed by a hinged squeezing mechanism conventionally carried by such mops. The scrubber pad may carry a detergent composition, such detergent being wetted by liquid in the sponge by virtue of holes in the central portion of the clip. The attachment, as a scrubber, is clipped to a sponge mop whenever floor portions are encountered which require greater abrasion than that obtained from the sponge alone and is clipped to the sponge mop (with a different pad thereon) whenever floor buffing/polishing is desired.

  • Patent number: 4793020
    Abstract: According to the invention, a resilient element is disposed between interconnected elements on a windshield wiper blade assembly such as cooperating primary and secondary yokes and a wiper blade element. Preferably the resilient element is a tape with a pressure sensitive adhesive backing or a coating that can be sprayed or painted on. The invention also comprehends a method of forming the windshield wiping elements by applying the tape or coating to stock material before the individual elements are stamped and formed.

  • Patent number: 4793023
    Abstract: A door closer and holder comprises a cylinder shell having a piston sealingly reciprocable therein. A spring biases the piston toward one end of the shell, and the piston is connected through the ususal apparatus to the door. At the one end the operating rod of a shuttle valve extends into the shell and is engaged by the piston as it approaches the end. The shuttle valve selectively directs the return fluid flow through sweep- and latch-control valves. The assembly also includes a solenoid-operated "bullet" which closes off the return flow to hold the door open. The angle of the openness at which the door is held may be selected by setting a cam on the holder drive pinion which engages a switch to activate the solenoid.

  • Patent number: 4793024
    Abstract: The hinge device comprises a recess formed in the rod or stem of a pair of spectacles and accommodating a leafspring. The spring has a conformation such that it pivots on the inner surface of the recess and cooperates with an element, rigidly associated with the front of the spectacles and pivotally connected to the rod. An adjustment screw is provided which extends into the recess and which interferes with the spring to vary the biasing action exerted on the element, when rotating the rod relatively thereto.

  • Patent number: 4793025
    Abstract: An apparatus for processing either a fresh or frozen piece of meat, in particular for frenching a rack of lamb. A pair of chain conveyers each incorporating teeth are mounted in adjacent spaced apart relationship on a bench. A piece of meat is transported along by and between the conveyer chains with the teeth thereof gripping the meat. The piece of meat is orientated on the conveyer to dispose a required section thereof to a cutting zone. At a first cutting station liquid jet cutting means are located to either side of the path of the meat to direct a liquid jet onto the predetermined section and cut thereinto. At a second cutting station a liquid jet stripping means is provided to remove the previously cut meat.

  • Patent number: 4793026
    Abstract: An apparatus for skinning fish includes a pressure pad carrying an oscillating knife blade and defining a presser surface which faces the circumferential surface of a skinning roller, the pressure pad being mounted to yield against spring force. The oscillating knife blade is guided in a pocket formed in the pressure pad. This arrangement makes it possible to skin fish fillets without any splitting of the tail portion.
