Abstract: 456,711. Electricity supply. KLANGFILM GES., 19, Saarlandstrasse, Berlin. April 16, 1936, No. 10973. Convention date, April 17, 1935. [Class 38 (iv)] [See also Group XXXVII] Condenser arrangements.-A glow-lamp 4 is energized by a source 1 over a switch 5, which may be actuated in dependence on the movement of a uniformly-moving kinematograph film so as to light the lamp as each picture moves through the picture aperture, and for such a short period that sharp pictures are produced. A condenser 3 shunts the lamp and switch and is in circuit with a resistance 6 such that the condenser can discharge while 5 is closed. A charging resistance 2 is of such value that it allows the condenser to be recharged while 5 is open, and while 5 is closed it cuts down the current so that the lamp current is derived mainly from the condenser. Resistances 2, 6 can be omitted if the internal resistance of 1 and the resistance of 4 are sufficiently high.

Patent GB-683915-A (GB)
Title: Improvements in or relating to the purification of methyl ethyl ketone by distillation
IPC: C07C45/82
Filed: 1950-05-10
Abstract: <PICT:0683915/III/1> The aqueous solution of methyl ethyl ketone is fractionated under an absolute pressure of at least 20 lbs. per sq. in., a M.E.K./water azeotrope is taken off overhead or as a side-stream, and is cooled whereby a M.E.K.-rich phase and a water-rich phase are formed, the M.E.K.-rich phase is refluxed to the column, anhydrous M.E.K. is withdrawn as bottoms, and this anhydrous M.E.K. is submitted to distillation at atmospheric pressure in order to free it from higher boiling impurities including degradation products formed in the high-pressure distillation.  In a modification, the azeotrope obtained from the high-pressure fractionation column, instead of being cooled, is fractionated at atmospheric pressure to give a distillate of decreased water-content (i.e. the normal azeotrope), which is refluxed to the high-pressure fractionation column.  Crude methyl ethyl ketone obtained by the catalytic dehydrogenation of sec. butanol and containing about 80 per cent M.E.K., 15 per cent sec. butanol, 2.5 per cent sec. butyl ether, 0.4 per cent water and 0.3 per cent acetone, is fed through line 1 to column P which is operated under a pressure of 60 to 80 lbs./sq. in. Acetone is removed from the head of column P, the M.E.K./water azeotrope is withdrawn as a liquid side-stream through line 3, while dry ketone containing high-boiling contaminants is withdrawn as bottoms and fractionated under atmospheric pressure in column A to give pure M.E.K. overhead.  The high-boiling contaminants are withdrawn from the system via line 11.  The side-stream from column P is cooled to 25 DEG C. and passed to decanter 4 where it separates in two layers. The ketone-rich layer is returned to column P via line 7. The water-rich layer is withdrawn from the decanter through line 8, and is preferably redistilled to the composition of the normal azeotrope.  The use of decanter 4 may, if desired, be avoided by passing the side stream from column P, via line 12, to column 13 wherein the side stream is distilled under atmospheric pressure to remove overhead the normal M.E.K./water azeotrope containing 11 per cent by weight of water.  The normal azeotrope is refluxed to column P through line 14.  Excess water is removed from the base of column 13.  If the feed contains isopropanol and ter. butyl alcohol, these alcohols are taken-off with the azeotrope from column P.  If the concentration of these alcohols is only small, phase separation in decanter 4 would not be affected, and the alcohols would be withdrawn from the system in the water-rich layer.  If the concentration of the alcohols in the azeotrope from column P is above 5 per cent, however, phase separation cannot be obtained, and the azeotrope is then distilled in column 13.  In either case, a mixture of M.E.K., isopropanol and ter. butyl alcohol may be obtained by dehydration; and may be recycled to the dehydrogenation furnace where the alcohols are converted into acetone and isobutylene respectively, which are readily removable from M.E.K.

Title: Improvements in the manufacture of foamed polyurethanes
Inventor: MORGAN DAVID BRERETON
IPC: C08G18/00
Filed: 1963-03-25
Abstract: Foamed polyurethanes are prepared by the reaction of organic polyisocyanates with hydroxyl group containing polymers containing at least two hydroxyl groups per molecule under such conditions that a foam forming gas is generated and incorporating in the reaction mixture a non-ionic organopolysiloxane containing at least one unit of the formula <FORM:1073312/C3/1> or <FORM:1073312/C3/2> wherein X and X1 are organic radicals connecting to silicon or oxygen through a carbon atom and containing the group <FORM:1073312/C3/3> wherein each of the atoms attached to the nitrogen atom is a polyvalent atom. Especially useful polysiloxanes are those of the general formula <FORM:1073312/C3/4> or <FORM:1073312/C3/5> wherein R is a hydrocarbon radical, X11 is either X or OX1, R1 is X11 or a hydrocarbon radical, R11 is a divalent hydrocarbon radical, m is an integer and n is zero or an integer and m+n is between 10 and 50.  Polyvalent atoms which may be attached to the nitrogen atom include carbon, nitrogen, oxygen and sulphur. The radical containing the group <FORM:1073312/C3/6> may be aliphatic, aromatic and heterocyclic, e.g. radicals derived from an amide, imide, carbamate, hydrazide, urea, acyl piperidine, acyl morpholine, acyl pyrazole, a mono- or diacyl piperazine, 2-pyrrolidone, 2-piperidone, 2-morpholinone, a caprolactam derivative, 2-oxazolidone, tetrahydropyridazine-6-one, hexahydropyridazine - 3,6 - dione, 2,5 - diketopiperazine, a hydantoin, a hydrouracil, a phthalimidine, an oxindole or a quinazoline. These radicals may be connected to the remainder of the polysiloxane by a divalent radical Z which in the case of heterocyclic ring compounds containing the C and N atoms of the <FORM:1073312/C3/7> group as part of the ring, is attached by a single valency to the N atom.  Z may be a divalent hydrocarbon radical which may be substituted by radicals such as -O-, -COO-, -NR- or -OR. Particularly suitable organopolysiloxanes are those containing lyophilic groups in the same radical containing the <FORM:1073312/C3/8> groupings or separately attached to other silicon atoms. Preferred lyophilic groups are phenyl, phenylene, octyl, octadecyl, cyclohexyl, benzyl or phenylether groups.  The hydroxyl group containing polymers may be polyesters, polyesteramides or polyethers.  In the examples, a polyether triol from propylene oxide and glycerol, an oxypropylated tolylene diamine and an oxypropylated trimethylol-propane are preferred.  An 80:20 mixture of 2:4 and 2:6-tolylene diisocyanate and a di(4-isocyanatophenyl)methane are the preferred polyisocyanates.

A vibration generator adapted to produce vibrations only when the critical frequency of the associated apparatus is exceeded comprises, a shaft 1 to which is connected a first eccentric mass 2, the latter also being connected to an outer cylindrical housing having end walls, and a second eccentric mass 3 rotatable on the shaft and connected to an inner cylindrical housing. A first auxiliary mass 9 is urged against mass 2 by springs 10 and carries a projection 8. A second auxiliary mass 6 is mounted at one side of mass 3 and is connected by bolts 7 slidable in mass 3 to a cross-bar carrying a projection 4. When the shaft is stationary a spring 5 urges projection 4 into a hole in the outer housing, so that when the shaft is initially rotated both housings rotate and the masses counterbalance each other. At a predetermined speed, mass 6 moves against spring 5 and withdraws projection 6, so that only the outer housing is driven. The outer housing now moves 180 degrees relative to the inner housing to a position determined by buffers (not shown) and the masses act on the same side of the shaft to produce a vibration. Mass 9 then overcomes springs 10 and moves projection 8 into a hole in the inner housing so that both housings are positively driven.
