Abstract: A U-shaped clip-on slide nut with two parallel sliding limbs provided with notch elements and capable of being clipped onto an undercut ridge. One sliding limb has a bore and the other limb is provided with a threaded bore aligned with the bore and accommodating a clamping screw. The invention facilitates fixing of a component on the ridge in that the bore is a blind bore, the clamping screw is a countersunk screw, and at least one sliding limb also has a screw receptacle for a securing screw.

Abstract: A closure for a container having a closure lower member and a screw cap in which the closure lower member is connectable with a base member to the container aperture. The closure lower member has a pouring spout connected to the base member. The screw cap has a cap bottom and a cap side wall with an internal thread adapted to be screwed onto and unscrewed from the pouring spout which has an external thread. The cap side wall of the screw cap in a region of its free end face terminates in at least one latching lug, the latching lugs of the screw cap co-operating with latching projections of the closure lower member to form a latch connection. In a screwing on direction the closure lower member has a shallow rising flank which merges into a steep latching flank and also forms the latching connection with the latching lugs, the connection being reversible by displacement of the latching lugs in relation to the latching projections.

Abstract: A nozzle cone and an oscillating fluid-jet nozzle system capable of producing relatively high-velocity, high-frequency oscillating fluid jets useful in waterjetting and other industrial spray applications. The oscillating fluid jetting apparatus includes a conduit and a follower which is mounted with respect to the conduit. A cam mechanically drives the follower so that the cam moves with respect to the follower. A portion of the conduit is secured with respect to a housing. An inlet block is secured with respect to the housing. An inlet end portion of the conduit is secured with respect to the inlet block. The inlet block has a fluid inlet opening which is in communication with the conduit.

Abstract: A filter ventilator for installation in an opening of a wall of a switchgear cabinet or the like, having a base housing receiving the filter, which is covered with a finned screen and which is connected with a ventilator on a side facing away from the finned screen. For a considerably simplified mounting of the filter ventilator, detent cams are molded on the base housing for fastening the ventilator. The detent cams engage bores in the facing flange of the ventilator. L-shaped holding elements are formed on the base housing which, facing the flange of the ventilator which faces away from the finned screen, have detent cams which engage bores of the flange. The L-shaped holding elements and the base housing form receivers, into which the ventilator, which is placed angularly offset on the base housing, can be rotated to a stop.
