An endless conveyor that is comprised of rotatably mounted transversely extending flights, the flights being adaptable for rotatable movement about the axis of the transversely extending flights.

A holder for presenting an assemblage of items to be taken on a one-by-one basis. The items may be in a pad or loose within an open-top receptacle. The holder includes a foldable support carrying adhesive attachment means, preferably pressure-sensitive adhesive with a release liner. The support is foldable so that the holder can be attached to a forward-or rearward-facing surface or to the underside of a horizontal surface.

The invention relates to a recuperator having a floating extended surface or reradiant insert, that is, an additional area accepting heat by convection and radiation from the hot combustion gases, not integrally connected with the original heat-receiving surface, for enhancing the rate of transfer of heat from the combustion gases to a vehicle flowing through the recuperator.

A rectangular safe having an interior compartment with a door hinged to the safe body and providing access thereto, the bottom of the safe extending below the floor level on which the safe is rested and hiding therein a concealed compartment hidden from normal view in the safe by a false safe bottom secured by hidden hinges at one end with the opposite end secured in position by an electrically operated magnet connected by suitable wires to a key operated switch mounted remotely from the safe, t...

A bucket for a public works machine which bucket has a shell including a sole plate and a back plate, the latter being movable between a closed position and an open position relative to the shell, in the latter of which positions the back plate defines with the sole plate a passage for unloading the bucket, a connecting member being provided on the back plate and movable relative thereto between a connected position in which it forms a part of the wall of the bucket in extension of the sole plat...

A valve assembly is disclosed for use in steam systems. The valve assembly is arranged with an integral filter which is transparent to the passage of foreign material in the steam line during valve open conditions and which is closed to such particles just prior to the time when the valve closes. The effect of such an arrangement being the protection of the valve from becoming stuck open due to the wedging of a particle between the valve and valve seat. The integral filter is shown as a coiled s...

A bathtub having a pump, comprising a tub having side walls one of which has an inner surface, an outer surface, and a thin portion made of magnetically permeable material, pump means secured to the inner surface of the thin portion, for taking in hot water from said tub and pressurizing the hot water, motor means secured to the outer surface of the thin portion and opposing said pump means, and a magnetic coupling means for mangetically connecting said pump means and said motor means.

A camera has a telescoping housing and an optical viewfinder. A pivotable or sliding member indicates certain data which may be in the nature of exposure information. The member for setting the data is operatively connected to the indicating member in such a manner that the indicating member is additionally pivoted or slid upon telescoping of the housing and the indicating means returns to its previous indicating position upon extension of the telescoped housing.
