Abstract: ABSTRACT OF THE DISCLOSURE            An object is produced from a tubular blank of thermo-plastic material of the type polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one single or several consecutive re-shaping operations.  A mechanical shaping device moves a transitional zone situated between thicker and thinner material along the blank and elongates simul-taneously the blank in the moving direction of the tran-sitional zone.  After the last re-shaping operation the thinner material has preferably an oriented state.  During the re-shaping operation the temperature of the material in the transitional zone is controlled at a level which, immediately before the re-shaping operation, is within or close to the range of the glass transition temperature.          In one embodiment the reduction of the wall thickness of the material is begun in a track in the wall of the blank and continues symmetrically around the track.          Clamping devices are used to maintain the axial position of the blank.  The blank is suitable for re-shaping for instance into a container in which the mouth too consists of oriented material.  The invention offers possibilities for materials savings by comparison with previously used methods, at the same time as the thermal and mechanical characteristics of the container are improved.

Abstract: Abstract of the Disclosure The invention relates to a method for hydrogenating coal whereby finely crushed coal is stirred into a slurry with a pasting oil.  The slurry is pressurized and heated in heat-exchange with hydrogenation products from the top of a hot-separator, and then, by the application of external heat, to the hydrogenation scorching temperature.  It is then subjected, in the presence of hydrogen, to catalytically-accelerated hydrogenation.  Thus, the hydrogenation product is broken down in at least one hot-separator into a top-product in vapour form and a bottom-product containing a heavy, fluid-distillate oil, non-distillable components, and solids.  In accordance with the invention, at least some of the distillate-oil, separated from the bottom-product in the hot-separator, is returned to the hot-separator.

Abstract: A B S T R A C T           A gun mount for machine guns or weapons of a similar kind comprises two mutually hinged swivel arms in staggered position, the one at a higher level than the other, the lower of the arms at its free end being pivotally mounted around a vertical pivot journal, which may be mounted e.g. on the roof of a motor vehicle at the edge of a gun pit, while the other, which is mainly formed as a vertically adjustable parallelogram connection, has fittings at its free end for pivotal fastening of a fork for swivel action of a weapon.         The gun mount has a mechanism for releasable locking of the two swivel arms in mutually pivoted positions.  This gun mount permits the use of guns of a relatively large calibre, as the force of recoil of the weapon cannot be transferred to the gunner through the swivel arms.

Abstract: ABSTRACT OF THE DISCLOSURE          Several methods are set forth for preparing polymetallic spinels by coprecipitating two or more metal compounds in a proportion to provide a total of eight positive valences when combined in the oxide form in the spinel crystal lattice.  The methods disclosed require coprecipitation of the metals in the hydroxide form or convertible to the hydroxide-oxide form, cal-cining the coprecipitate, and finally sintering the calcined material at about one-half its melting point or greater, thereby forming a spinel which has a density of greater than 50 percent of the theoretical density of spinel crystal.  Also disclosed are techniques for preparing spinels having more than two metals incorporated into the spinel lattice, as well as a separate oxide phase associated with the spinel crystallites, and slipcasting compositions.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of forming an article to a final form in a final cavity between two dies by forming a preform having the general shape of the final form of the article and thereafter measuring the amount of material contained in the preform and removing any material from the preform in excess of the amount of material required to completely fill the volume of the final cavity and then enclosing the preform in the final cavity to completely surround the preform and conform the preform to the shape of the final cavity to produce the final form of the article.          Preferably, the preform is first formed by compacting powder metal so as to have a greater dimension in one di-rection than the final form and a lesser dimension in a transverse direction.  After weighing the preform and re-moving excess material from the exterior of the preform, the preform is placed between two dies of a press which close to initially apply pressure to the greater dimension of the preform to reduce that dimension to the final desired dimension while increasing the lesser dimension to the final desired dimension of the final preform.

Abstract: Abstract This invention is directed to an improved cerebro-spinal fluid shunt in the form of a ventricular catheter for controlling the condition of hydrocephalus by reliev-ing the excessive cerebrospinal fluid pressure.  The invention is further concerned with an improved method for fabricating the catheter and an improved method of shunting the cerebral fluid from the cerebral ventricles to other areas of the body.      The obstruction of cerebrospinal fluid flow pathways or its inadequate absorption via the arachnoid villi into the venus blood of the brain results in hydrocephalus. Surgical correction involves pressure controlled shunting of the cerebrospinal fluid.  The shunt will fail to func-tion if the inlet ventricular catheter apertures become blocked.  Shunt flow failure will also occur if the ven-tricle collapses due to improper valve function causing over drainage.      The ventricular catheter 10 of the present invention comprises a multiplicity of inlet microtubules 12.  Each microtubule has both a large opening 16 at its inlet end and a multiplicity of micoroscropic openings 18 along its lateral surfaces.      The microtubules are perforated by a new and novel ion beam sputter etch technique.  The holes are etched in each microtubule by directing an ion beam 20 through an electro formed metal mesh mask 28 producing perforations having diameters ranging from about 14 micron to about 150 microns.      This combination of a multiplicity of fluoropolymer microtubes, the numerous small holes provided in the lateral surfaces of the tubes, and the hydra-like distri-bution of the tubes provide a new and novel catheter. This structure assures a reliable means for shunting cerebrospinal fluid from the cerebral ventricles to selected areas of the body.

Abstract: ABSTRACT OF THE DISCLOSURE     A water-conserving toilet is disclosed and includes a bowl for receiving waste and a waste outlet extending laterally from the bowl and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl for preventing gaseous flow through the trap.  A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl in a direction to cause said body of liquid to be dis-charged through said outlet.  An enlarged chamber commun-icates with said bowl outlet for receiving waste from the bowl.  An outlet extends outwardly from the chamber and is adapted for connection to a sewer inlet.  The chamber outlet defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the chamber in use.  The toilet also includes means communicating with the chamber and adapted to relieve increase in gas pres-sure caused by liquid entering the chamber from the bowl whereby back pressure resistance to flushing of liquid from the bowl is reduced.
