Novel mixed esters of isocyanuric acid have been prepared. These bis-(hydroxyphenylalkylene)alkyl isocyanurate compounds provide excellent stabilization for organic materials against oxidative, thermal and photochemical degradation. The stability of .alpha.-monoolefin homopolymers and copolymers is particularly enhanced by the use of stabilizing amounts of the bis-(hydroxybenzyl)isocyanurates.

The present invention relates to a device to be used in roll stands containing inserts and adjusting spindles and movable intermediate pieces therebetween, and consists in designing the intermediate piece so as to be composed of interengageable parts, such as cogged discs which are displaceable in relation to one another from a position of nonengagement into a position of engagement, whereby the overall height of the intermediate piece is reduced and free handling space is provided beneath the a…

A composition for treatment and treatment of certain skin diseases is disclosed. The treatment combines furocoumarins, UV-A radiation, and a benzylidene-camphor derivative. The composition and treatment produces the desirable results of the furocoumarin/UV-A radiation treatment without the undesirable phototoxic side effects.

Used lubricating oils, particularly those containing additives such as V. I. improvers, dispersants and the like, are reclaimed by a preliminary treat with a C.sub.4 to C.sub.5 aliphatic alcohol, which causes the separation of a layer of sludge which contains polar additives and oxidation products. The desludged oil is then subjected to conventional lubricating oil refining steps such as treatment with fuming sulfuric acid followed by neutralizing, washing, and clay treating steps. Alternatively…

Securing devices to be used with aircraft for securing the aircraft to the ground. The securing devices include a rear securing device operatively connected with the tail region of the fuselage of the aircraft and a pair of forward securing devices operatively connected with a wing extending laterally from the fuselage with the forward securing devices situated equidistant from the fuselage. The rear securing device has an expanded position extending and compressed between the fuselage and the g…

A burner mechanism of used oil wherein the used oil of heated condition is compulsorily mixed with pressured oil, mixture of the used oil with the air is then filtered so as to convert the air voids in the mixture into finer particles, filtered mixture is then again compulsorily mixed with pressured air and is finally supplied to a burner element. The mechanism may advantageously be provided with a rotary mixed for a better mixing of air with used oil.

Developing apparatus includes two endless bands each of which is horizontally disposed, carries a plurality of horizontally spaced magnets depending therefrom and traverses the path of a photoconductive sheet having a latent image thereon whereby to brush said sheet with an excess of developer carried by a first of said belt and magnets and subsequently to brush the developed sheet with magnetic carrier particles carried by the other of said belts and magnets thereon to thereby remove excess ton…

An apparatus is described for cleaning the mortar and other protruding material from the surfaces of used building bricks. The apparatus has a perforate turntable with an expanded sheet metal lath removably supported thereon and substantially covering the turntable. The expanded sheet metal provides edges upon which the bricks are supported, so that these upstanding edges scrape the protruding material from the brick surfaces. An upstanding band surrounds the brick on the turntable to keep the b…

Thioureidobenzene compounds having the general formula ##EQU1## wherein R and R’ are lower alkyl groups and X is oxygen or sulfur atom have high miticidal and fungicidal activity.
