Mounting assembly for soothing teats

Abstract: A mounting assembly for infants' soothing teats comprising a teat nipple with an integral shaft portion made of an elastic material, a clamp member inserted into the shaft portion of the teat nipple, and a shield type mouth plate mounted on the shaft portion of the teat nipple wherein the clamp member includes an abutment surface and one or a plurality of integral yieldably movable locking elements adapted to cooperate with the abutment surface to safely retain the soothing teat assembly in its assembled relationship. The locking elements may consist either of articulated lugs being biased into a predetermined locking position by their inherent resiliency, or of slidably movable wedge members adapted to be selectively adjusted into a retaining position.

Method of and apparatus for removing puncture-resistant tubes from tires

Abstract: An apparatus for removing puncture-resistant tubes from tires includes two symmetrical squeezing plates, a jack located between these two plates, in a plane parallel to the lengthwise direction thereof and a base plate disposed transversely with respect to the squeezing plates, which base plate furnishes support for the squeezing plates and for a tire which is to have its associated puncture-resistant tube removed. An accommodation for the tire whose tube is to be removed, is delimited by the aforesaid squeezing plates, jack and base plate. A method of removing puncture-resistant tubes involves subjecting a tire containing a puncture-resistant tube simultaneously to a lateral squeezing action on two diametrically opposite zones thereof in a given plane, and to a first thrusting action on a zone thereof in a plane, perpendicular to the given plane, and then to a thrusting action on a zone opposite to the zone which was subjected to the first thrusting action.
