A bowl liner and a bowl for use in gyratory cone crushers in which the body of the liner has improved wear-resistant features and the liner is mounted in a shock-free manner to greatly increase the life of the liner. A circumferential, inwardly extending bowl ledge is provided with sockets through which inserts which are fused to the liner body project. The inserts have bores threaded to receive spring-loaded mounting bolts yieldably connecting the liner to the bowl.

Apparatus for metallizing parts of a body by dipping into molten metal includes a plurality of part vessels or dip tanks with different heights and widths so chosen in accordance with the parts of the body to be metallized.

Prosthesis consisting of a mesh material impregnated with an antibiotic, antiseptic, antispore medication or a combination of these which surrounds a conduit leading to the skin, such as the urethra, and having an end portion thereof embedded in a water-repellent substance which protrudes from the end of the conduit and the surface of the skin and a cap therefor.

Radiation detection is accomplished by sensing the piezoelectric response to the expansion and contraction in a crystal element due to the heating effect of the carrier energy to be sensed. Sensitivity to a subcarrier is enhanced by utilizing a frequency (of interrupted or continuous wave subcarrier) corresponding with a mechanical resonance frequency of the crystal element. The device is analogous to a conventional resonant r.f. detector element. Uses to which such prior art devices are applied...

A temperature indicator which consists of a suspension of a cuprous mercuric iodide complex in a transparent carrier, which is able to protect the complex indicator compound against deterioration from sublimation of the mercuric part of the complex and to protect the same against the detrimental influence from the ambient atmosphere such as oxygen. The indicator may be further protected by a transparent cured cover, and it will change its color at 65.degree.-75.degree. C from red to black, when ...

A mechanism to enable a woman who is wearing hair curlers to lie comfortably in bed. The mechanism consists of an external shell, the interior of which consists of rib sections of cushioned material mounted on rollers, the sections of cushioned materials being so located as to serve as resting surfaces for the head, while the hair curlers occupy the space between adjacent rib sections of padded material. The mechanism permits relatively frictionless movement with relation to the external shell o...

An improved method and means for curling hair uses relatively slidable combs to apply lateral forces to the hair as the teeth are drawn through the hair.

An anus blocking hollow ball insertable through an anus and thereafter inflated for blocking said anus and means extending from said ball for preventing said ball from moving deeper into said anus than desired.

An apparatus for positioning coating pots at a coating line station constructed in a deep well such that the top of the coating pots is just below the level of the coating line. In one embodiment, the two coating pots carried on transfer cars are conveyed through a 180.degree. angle between a working position and hold position by a turntable mounted in the bottom of the well. The coating pot when in the hold position is adapted to be transferred to an adjacent repair area along rails extending r...

A hair setting assist device comprises a removable rigid cap having spaced regions at which pivot pins are disposed for receiving forms for curls and other locations containing supports to which independent rollers can be secured.
