Abstract: PRODUCTION OF FLUID FERTILIZER FROM         PHOSPHORUS FURNACE WASTE STREAM     ABSTRACT           Processes and compositions of matter are disclosed for the production of liquid fertilizers wherein wastewater from a phosphorus smelting furnace is incorporated in liquid fertilizer processes.  The wastewater replaces water evapo-rated and the wastewater dissolves fertilizer salts.  A serious water pollution problem is avoided when wastewater is incor-porated in liquid fertilizers.  The invention discloses a process for making orthophosphate suspension fertilizer wherein impure phosphoric acid is neutralized in the condensing system, water from the condensing system is bled off, and a suspending clay is added to produce orthophosphate suspension fertilizer.          In this process, phosphorus sludge made at phosphorus furnaces is used to produce suspension fertilizer, and wastewater from phosphate smelting furnaces is recovered.  New compositions of matter are disclosed.  A process is disclosed for making phos-phoric acid with low impurities content wherein phosphorus sludge is burned to make impure orthophosphoric acid and the impure acid is recycled to an agglomerating step in a process for making elemental phosphorus.

Abstract: ARRANGEMENTS FOR PUTTING LIFE-BOATS TO SEA IN FREE FALL                         Abstract An arrangement for putting lifeboat (10) to sea in free fall. The arrangement comprises a lifeboat-supporting beam (11), which can be pivoted between substantially horizontal and oblique downwardly extending positions, together with a fastening arrange-ment with associated lock (20), for securing the life boat (10) on the beam (11) during pivoting of the same between said horizontal and said oblique downwardly extending position. The lock (20) is adapted for automatic release of the lifeboat (10) relative to the beam (11) at a definite angular position of the beam, for example after a pivoting of the beam 35° from the starting position. During pivoting of the lifeboat together with the beam the lifeboat can be subjected to an axial movement along the beam for an introductory free fall movement immediately the beam has reached or has passed said angular position.

Abstract: ABSTRACT OF THE DISCLOSURE         A free-standing medical service column has front and rear chases with service outlets mounted on at least the front side for connection with fluid and electrical conduits.  The column includes vertically extending tracks at each corner, which tracks extend substantially the height of the column.  Brackets, holders, and equipment are connected to the tracks by means of locking slide assemblies.  Each slide assembly includes a base and a slide element formed of a low-friction material.  A screw interconnects the base with the slide element such that rotation of the screw moves the slide toward the base and against the wall of the channel to frictionally secure the slide within the channel.  Members secured to the column by means of locking slide elements may also carry a bracket.  The bracket includes a plug formed of resilient material, which plug is received in a cylindrical bore of the member.  When the bracket is rotated to a desired position of adjustment, the plug is expanded radially out-wardly into frictional engagement with a wall of the bore to affix the bracket immovably to the member.  The chases are formed entirely of non-flammable material to eliminate the need for enclosing the electrical lines within metal conduits.

Abstract: METHOD AND APPARATUS FOR RETORTING PARTICULATE SOLIDS       HAVING RECOVERABLE VOLATILE CONSTITUENTS     ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed for retorting particulate solid materials, particularly hydrocarbon-con-taining materials such as oil shale, oil sands, tar sands, coal shale, coal tailings, and the like, for the recovery of a volatile constituent such as oil or gas.  A rotary retorting apparatus is employed which consists of a cylindrical drum, or other similar regularly shaped chamber, with a substantially horizontal axis of rotation and having multiple compartments for retorting and combustion and, optionally, spent solids cooling.  The apparatus further includes solids transport chutes for forward and backward circulation of solids, arranged for the intercompartmental transfer of solids with the capa-bility of additions at one or more points in each compartment.          Employing the method and apparatus, particulate solids feed-stock is heated by recycled spent solids material to remove the volatile constituent of the feedstock in the retort section.          Another feature of the invention employs direct solids-to-gas contact established by lifting and cascading reacting solids through hot gas streams such that throughput, high thermal efficiency, low energy input, among other advantages, are obtained in producing high yields of volatile product.  In particular, high oil yields and gas yields are obtained when processing oil shale, but with low sulfur oxides, nitrogen oxides in the flue gases and reduced hydrogen sulfide in the retort gases.

Abstract: ABSTRACT OF THE DISCLOSURE           The method relates to the hardening of form substances made of building materials and containing binding agents in a pressure chamber of an autoclave to which is conveyed a gaseous heating medium, the temperature of which is increased during a heating-up phase up to a given upper limit value.  During a hold-ing phase, the temperature is maintained at least until a given equalization temperature is reached on the inside of the form substances.  Subsequently, during a cooling-down phase, the tem-perature is reduced by reducing the pressure to the expulsion temperature.  Porous light building materials in a conventional process would absorb a high amount of water through the condensa-tion of water resulting from steam having been conveyed into the autoclave for the purpose of hardening.  However, in order to produce form substances of a low water content economically, according to the present invention, on the one hand, steam is replaced by gas which is maintained below the evaporation temper-ature of water through sufficient increase in pressure, and, on the other hand, as a replacement or complement, heat is conveyed to the inside of the pressure chamber before the cooling-down phase and an increase in the temperature of the steam beyond the given limit value is prevented by blowing off steam, thereby attaining an integrated drying process.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel zinc oxide lightning preotector is disclosed, wherein end plates are mounted at the ends of an insulator and a zinc oxide element section is arranged between the cover plates.  Support metal members are mounted on the cover plates between the zinc oxide element section and the insulator to support an insulation cylinder therebetween.  A space is formed between at least an end of the insulation cylinder and a corresponding cover plate to absorb the expansion or contraction of the insulation cylinder due to temperature changes, thus preventing the insulation cylinder from deforming.  At the same time, the elements are eccentrically arranged against the insu-lation cylinder, thereby to cause the gas flow along peripheral direction so that the laminar flow is changed into a turbulent flow.  Thus the heat conduction is improved to improve the radiation characteristic of the zinc oxide element section.
