Patent GB-404081-A (GB)
Title: Improved method and apparatus for the fractional distillation of immiscible liquids
IPC: C10C1/04
Filed: 1932-09-06
Abstract: <PICT:0404081/III/1> In the fractional condensation of a mixture of steam and vapours of a liquid immiscible with water, the mixed vapours are passed into a fractionating column, from the base of which condensate is removed, while the vapours leaving the top of the column are fractionally condensed, the middle fraction and the steam being condensed together and then separated, and the middle fraction only returned to the fractionating column as reflux.  Benzol removed from coal gas by washing with oil is recovered by distilling the oil with steam and passing the vapours into a column 1 where the heavier constituents condense and are removed through a pipe 3.  The vapours pass off to a condenser 4 where the steam and middle fraction are condensed and the condensate is removed to a separator 6 where it separates into water and a light oil, the latter only being returned to the column 2 through a pipe 7.  The condenser 4 may be cooled by water or by the oil to be distilled or by both.  The vapours leaving the condenser 4 are condensed to "once run" benzol.  The vapours may be passed through a dephlegmator before entering the column 1 and the condensate formed passed into the separator.

Class 64(2) Insulation, e.g. glass wool, is protected by an envelope 5 of sheet material, e.g. metal supported from a body such as a pipe 2, by spacing-strips 1, 1a each resting on an asbestos pad 3 and held on to the body by metal strip or wire 4. Either the triangular supports 1a or the L-shaped supports 1 may be used solely but as shown the supports 1a are used at the top to take the load. The supports may be secured to the envelope 5 by screws. Pieces of sheet metal are bent to cylindrical form and the edges screwed together to form the envelope but at pipe bends the pieces are of part-cylindrical shape. Interruptions in the insulation are closed by half discs of sheet material, a truncated cone wall or sanded flintkote.

Abstract: 1287029 Driving multiple axles BORGWABNER CORP 22 May 1970 [5 June 1969] 25037/70 Heading B7H In transfer gearing 12 for driving the front and rear axles of a vehicle, an interaxle differential 25 has a planet carrier 26 connected to an input shaft 23, the ring gear 30 of the differential 25 is connected to an output shaft 38 for driving the rear axle, and the sun gear 28 of the differential 25 is connected to an output shaft 42 for driving the front axle through a chain drive 41, 43, 44 and an hydraulically-actuated clutch 45 which is wholly or partly disengaged when the vehicle is driven in reverse. The input shaft 23 is driven from an engine 10 through an automatic transmission 11. The output shafts 38, 42 are connected to front and rear axle differentials 13, 16 through respective drive shafts 15, 17. The chain drive element 41 has less teeth than the chain drive element 43 and a one-way sprag clutch 40 prevents the planet carrier 26 from overrunning the sun gear 28 in the forward direction so that overrunning of the front wheels relative to the rear is unrestricted but the rear wheels can overrun the front only to a limited extent. As shown, the clutch 45 is engaged by fluid pressure applied to an annular piston 55 from a source 60 only when a forward drive clutch 61 in the transmission 11 is operative. In a modification, Fig. 3 (not shown), a reduced pressure is applied to the piston 55 when driving in reverse so that slipping of the clutch 45 will accommodate overrunning of the front wheels.

Filed: 1928-08-31
Abstract: 322,225. Wright, G. M., and Smith, S. B. Aug. 31, 1928. Television. - The output from a photoelectric cell 2 is rendered intermittent by means of a commutator 4 which shortcircuits it at the required frequency so as to facilitate amplification by the valve 5 and amplifier 6,. a shunt condenser 3 being provided also. The commutator 4 may be a rotary commutator geared to or driven synchronously with the scanning disc of a television transmitter comprising the cell 2 so that the frequency of intermittence is definitely related to the scanning frequency. Where the light-intensities are weak, however, the commutator may be a thermionic or other noise-free short-circuiting device. The frequency of intermittence may be such as to give a grain 100 dots per inch, and the duration of the short-circuit periods may be adjustable for the purpose of ensuring maximum output from the valve 5.

Abstract: Formylamino-malonic esters are obtained by the catalytic hydrogenation of nitroso- or isonitroso-malonic esters in the presence of formic acid or an ester thereof.  The hydrogenation may be effected at atmospheric temperature and raised pressure, e.g. 10-100 atm., but the reaction mixture is preferably heated after the hydrogenation, in order to complete the formylation; the mixture may also be dried and/or purified before it is heated. Examples are given of the production of diethyl formylaminomalonate by the hydrogenation of diethyl isonitrosomalonate in the presence of palladium-charcoal and ethyl formate or formic acid.  The production of dimethyl formylaminomalonate is also mentioned.
