Title: Crystallisation apparatus and method of operating the same
Inventor: EBNER KARL
IPC: B01D9/00
Filed: 1958-05-21
Abstract: Apparatus for obtaining uniform granular crystals from saturated solutions comprises an evaporating vessel for the partial evaporation in vacuo of the solvent, the vessel having: a conical bottom; a vapour outlet adapted for connection to vacuum means; a bottom outlet for crystals; an internal funnel-shaped attachment extending downwardly into the conical bottom with its top edge located above the intended liquid level in the vessel and not <PICT:0835659/III/1> touching the vessel wall; a system for circulating the liquor from closely below the intended liquid level to a location above the mouth of the funnel so that the solution can flow thereinto; means for injecting air or other gases into the circulating system to raise the solution in the manner of an air-lift pump, and means for introducing the solution to be treated into the apparatus. The preheated solution is preferably introduced into the circulating system in a proportion sufficient to raise the temperature of the circulating liquor by 1 DEG  or 2 DEG  C.  In the apparatus shown air introduced through inlet 4 causes circulation of the liquor to be crystallized in evaporator 1.  Vacuum exerted at 10 concentrates and cools the liquor discharged at 12 into funnel 5 to produce a supersaturated solution which passes through cylindrical extension 6 at the bottom of which it meets partially formed crystals and deposits its excess solute thereon.  The larger crystals sink and are removed through outlet 8 whilst smaller crystals are maintained in suspension by the circulating liquor.  Fresh warm liquor is supplied through inlet 15 to restore the temperature of the liquor circulating through pipe 2 which is returned to the funnel 5 at 12.  Excess liquor is removed through line 16.  The amount of air, injected through valve 14, required to effect circulation is kept to a minimum by making the ratio H : h lie between 10 : 1 and 20 : 1.  The air is preferably warmed to the saturation temperature of the circulating liquor before admission.  In the preferred mode of operation the temperature drop in the evaporator is only 1 DEG  or 2 DEG  C.  In a modification a number of evaporators are arranged in series, the discharge pipe 16 of one evaporator being connected with the inlet pipe 15 of the next. In operating this embodiment it is preferred that the temperature drop between the first and last evaporators is 4 DEG  to 7 DEG  C. and the rate of transfer of liquor sufficient for the incoming liquor to raise the temperature of the circulating liquor by 1 DEG  or 2 DEG C.

Abstract: 557,675. Electric tests. ZIEBOLZ, H. Nov. 20, 1942, No. 16481. [Class 37] [Also in Group XXXVIII) A force (e.g. a weight) to be measured deflects a lever 10 which by means of a magnet 12 or a charged plate deflects a cathode beam to vary the current in a coil G carried by the lever and co-operating with coils R, S and so counteract the force.

Title: Improvements in the manufacture and production of high quality lubricating oils
Filed: 1930-05-28
Abstract: Lubricating oils are obtained by cracking paraffin waxes so that liquid products having an iodine value of at least 150-200 are formed and then subjecting these products to condensation in the presence of catalysts having a condensing action e.g. anhydrous halides, boron fluoride, &c.  The cracking reaction is preferably carried out in stages with reduction of pressure and at temperatures of 440-540 DEG C.  Cyclic hydrocarbons e.g. naphthalene anthracene, cyclohexane, or terpenes may be added to the cracked products before the condensation stage.  100 kgs. soft paraffin wax of meltingpoint 38-40 DEG  C. are cracked at 440 DEG  C. and 3 atmospheres pressure.  5 kgs. per hour of the product are led at 480-500 DEG  C. over a catalyst of porous iron and nickel.  85 kgs. of liquid products having an iodine value of 210 are thus obtained and are mixed with 8 kgs. anhydrous aluminium chloride the temperature rising to 110 DEG  C. and being maintained at that point for an hour.  The oily layer is distilled up to 300 DEG  C. and, after separation of benzines, 15 kgs. of lubricating oil, and 6 kgs. cylinder oil are obtained.  In another example calcium silicide is used as catalyst and the cracked products are mixed with decahydronaphthalene and aluminium chloride.

Abstract: 1,269,183. Semi-conductor devices. M. GENSER. 8 April, 1970, No. 16762/70. Heading HlK. A dopant-containing coating is produced by applying an aqueous solution of the dopant and a water soluble polymeric carrier to a semiconductor surface. The coated surface is then heated to diffuse-in the dopant, the polymer decomposing into water and carbon dioxide which are removed by a gas flow. In a first embodiment, an Si wafer is provided with an oxide mask and is placed on a "spinner" of the type used for applying photoresists. A drop of an aqueous solution of polyvinyl alcohol and boric acid is placed on the wafer which is spun to form a uniform coating over the mask. The wafer is then heated to diffusein the boron to form P-type regions. Indium or gallium trichloride may be used instead of boric acid. In a second embodiment an unmasked wafer is coated with an aqueous solution of polyvinyl alcohol and boric acid which has been photosensitized by addition of ammonium dichromate. An optical mask is placed on the coating which is then irradiated with U.V. light. The exposed areas of the coating become water insoluble and the remaining areas are removed by dipping in water. The wafer is then heated to diffuse the impurity into the semi-conductor. The Specification contains a list of other water soluble polymers.
