Abstract: In a glass washing machine having a glass carrier rotatable on an upright axis, half of the carrier is always in an access zone where glasses can be loaded onto the carrier and removed from it, the other half in a cleansing zone where detergent solution is discharged from a first set of spray nozzles and germicidal rinsing solution is discharged from a second set of nozzles. Upon actuation of a pushbutton switch, the carrier rotates through 180.degree., always in the same direction, then stops until the switch is again actuatd. Liquids are discharged from all nozzles while the carrier rotates. Detergent solution is recirculated, but fresh detergent solution is introduced during a predetermined portion of each period of carrier rotation.

Abstract: A fastener for releasably securing an object to a panel having a hole therethrough comprises a screw having a screw head attached to the object and having a threaded screw shank insertable through the hole in the panel. The fastener further comprises a flexible resilient plastic push-on/screw-off nut having a bore therethrough which is slidably mountable onto the threaded screw shank into engagement with the panel. The nut has a resilient flexible concave nut head which operates to seal the panel hole and has a nut shank defining two resilient flexible legs, each of which has internal nut threads for engaging the threaded screw shank. The nut also comprises webs, each connected between the nut head and the outer side of a leg, which operate to force the nut threads tightly against the screw thread in locking engagement when the nut head is forced against the panel. The nut is removable from the screw by rotation in a conventional manner.

Abstract: In normal washing operation of the beverage glass washer of the invention, detergent solution discharged from a set of washing nozzles is collected in a tank from which a recirculation pump withdraws it and delivers it back to those nozzles for redischarge; and rinsing liquid from another source is delivered to a set of rinsing nozzles for discharge from them. For cleaning and deliming all nozzles, the tank is filled with a cleaning solution and the two sets of nozzles are connected, either by opening a normally closed solenoid valve in a permanent connection between the two sets of nozzles or by slipping opposite ends of a suitably sized hose over a cylindrical nozzle body of each set. The recirculation pump then flushes the solution from the tank through all nozzles of both sets.
