Abstract: An apparatus for drying fruits or other products comprises a drying unit and a connected cooling unit having conveyors therein for moving products to be dried from the cooling unit through the drying unit and then back to the cooling unit in a succession of cycles. Hot air from a heating unit is supplied to the end of the drying unit adjacent the cooling unit, and is directed through the drying unit away from the cooling unit for exhaust from the end of the drying unit remote from the cooling unit whereby, as the products being dried move through the drying unit away from the cooling unit they pass successively through air which is increasingly less hot and less dry and as said products thereafter move through the drying unit back toward the cooling unit they pass through air which is increasingly hotter and drier before reaching the cooling unit to start a new cycle.

Abstract: A compact lamp unit and associated socket for use in a projection system such as a slide projector, microfilm viewer, and so forth. The lamp unit includes a reflector molded from a plastic material and an electric lamp secured within the reflector. In order to decrease the axial dimension of the reflector and to avoid the use of pin connectors, electrical contacts for the lamp are pressed into recesses formed in the outer surface of the reflector. The reflector includes an opening at its apex through which electrical leads from the lamp extend outwardly of the reflector. The electrical leads are secured to the contacts by being forced into the recesses along with the contacts. This construction technique is fast and simple.The lamp unit also includes a handle to enable a heated lamp unit to be replaced by the user and a guide means to enable the lamp unit to be oriented quickly and accurately upon insertion into the socket.

Abstract: Electrically conductive elastomers are prepared by adding polyfunctional tertiary amine compounds to halogenated polymers. The resulting elastomers have resistivities in the range that makes them suitable as conductors for many electrical and electrostatic applications. These ranges are generally in the area of 1.times.10.sup.3 to 1.times.10.sup.7 ohm cm as measured by the methods of ASTM 257. A preferred elastomer is prepared by adding a polyfunctional tertiary amine such as N,N,N',N' tetramethyl-1,3-butanediamine to polychloroprene prior to vulcanizing under conventional vulcanization conditions. The resulting elastomers possess useful electrical conductivity, as well as the desirable physical and chemical properties of conventional elastomers. A roller for current-assisted printing or electrostatic-assisted printing having an external surface layer comprised of the novel electrically conductive elastomer is described.
