Abstract: LOCKING DEVICE            Abstract of the Disclosure A panel locking device for Assembling and inter-locking two double wall panels along their adjoining edges structurally integrates the locking device within the two panels and retains the panels tightly locked together under tension under all conditions of subsequent thermal expansion and contraction.    The locking device incorporates a locking pin which is driven through a lug and over a channel.           Each panel has a perimeter frame.  One edge of the perimeter frame of one panel forms a male channel, and the adjoining edge of the perimeter frame of the other panel forms a female channel.           A lug is connected at one end to the web of the male channel.  The outer end of the lug has a pin receiv-ing and panel aligning hole extending through the lug.           The web of the female channel is formed with a lug receiving slot extending through the web.           An aligning and locking pin has a tapered tip; and when the panels are aligned edge-to-edge, the hole in the lug extends far enough above the backside of the female channel web to permit entry of the tapered tip of the pin.  As the pin is driven into the hole and up to the full diameter of the pin, the lug is pulled upward through the slot in the female web.  This produces elastic deflection of the male and female webs to retain the panels tightly locked together and structurally integrates the locking device into the perimeters of the two panels.  The stressed deflection of the webs thus provides a constant and permanent force which urges the two panels together in tightly locked engagement.

Abstract: ABSTRACT OF THE DISCLOSURE Para-xylene is selectively adsorbed from a C8 aromatic hydrocarbon feed by a crystalline selective adsorbent.  The para-xylene is subsequently desorbed by contacting the resulting adsorbent with a 1-(lower alkyl)-4-isopropylbenzene desorbent, wherein the lower alkyl group contains one or two carbon atoms.  The desorbent effectively desorbs the para-xylene from the adsorbent, and the para-xylene may be produced as an enriched product.

Abstract: REFRIGERATION APPARATUS FOR VISCOUS PASTE SUBSTANCE               Abstract of the Disclosure Refrigeration apparatus for quickly reducing the temperature of and for solidifying a viscous paste substance of the type that is produced as a byproduct in animal slaughtering.  Because the material is high in proteins, it has substantial commercial value.  The apparatus includes a relatively large cylindrical drum the surface of which is cooled by circulating a refrig-erant through the interior of the drum.  The drum is continuously rotatively driven and there is an inlet roll and a nozzle for introducing the relatively warm viscous paste in the nip between the drum surface and the roll.           Downstream of the inlet is one or more compression rolls which flatten the paste material further.  Spaced cir-cumferentially from the inlet is an outlet that includes a scraper blade and a hold down roller immediately upstream of the scraper blade so that after the material traverses the apparatus, it is refrigerated, relatively stiff and ready for further processing and shipment.

Abstract: Kobelt 17 c/w CALIPER BRAKE ASSEMBLY     ABSTRACT OF THE DISCLOSURE           Caliper brake assembly using a cam structure to actuate brake shoes to permit selection of a wide range of braking forces and to increase design flexibility.  The assembly has a frame journalling a pair of opposed arms with opposed brake shoes hinged adjacent opposed inner ends of the arms to brake a disc sandwiched between the shoes.  The cam structure includes a cam member having a cam surface which cooperates with a brake actuator so that the cam surface is displaced by the actuator.  A pair of cam followers cooperate with the respective arms and the cam surface during brake actuation to rotate each arm about a respective hinge axis relative to the frame so as to force the shoes against the disc.  In one em-bodiment the cam member is displaced parallel to the hinge axes and each cam follower includes a swivellably mounted roller to accommodate swinging of the arms.  In an alternative embodiment, the cam has double-acting wedges in which the actuator effectively floats between the arms,  A lever, or a spring within the actuator, permits the brake to be engaged without fluid pressure thus permitting the brake to be used as a static brake also.

Nozzle means  arc provided in a cover having converging guide grooves in its lower surface, the nozzle being located between the grooves and at a point a short distance behind a point at which the grooves join.  The edges of the web are in close proximity as they enter the sealing region and a narrow cover is provided at the sealing region to block entrance of air and exit of the gas. Additional features relate to the thorough mixing of gas with ground coffee in a bin to the supply of gas into filler tubes and to the supply or gas into a web of an outer wrap material as it is being formed.

Abstract: PROCESS FOR THE PURIFICATION OF WASTE WATER         Abstract of the Disclosure:         The waste  water being formed upon the preparation of hydroxy aromatics, preferably of resorcinol and .beta.-naphthol, by caustic alkaline melt of the corresponding aryl-sulfonic acids or aryl sulfonates is purified by a wet oxidation with oxygen or oxygen-containing gases at temperatures of from about 100 to 370°C and under a pressure of from about 1 to 300 bar.  The COD-decomposition rates amount to about 90% and more.         This process provides a sulfate, especially sodium sulfate, which is sufficiently pure for further use without com-plementary purification stages, if the hydroxy aromatics are prepared by means of a caustic soda melt.  The obtention of the pure salt is important for the economy of the process.
