Title: Improvements in methods of and means for the recovery of a vapour from a gas mixture
IPC: B01D1/30
Filed: 1948-09-20
Abstract: Solvent is recovered from material treated with an impregnating agent dissolved in the solvent in apparatus wherein hot gas is passed over the material and then through a direct contact condenser fed with cooling liquid below 0 DEG  C. and a surface condenser.  Paper 20 to be impregnated in a basket 12 is contained in an impregnating and drying chamber 10 to which bitumen or asphalt dissolved in trichlorethylene is pumped from a storage tank 116, Fig. 2, and after a time pumped back.  Air is circulated by a fan 28, Fig. 1, via ducts 26, 30, 56 and 44 and heating elements 50 and for an initial period also via duct 58, byepassing the heating elements 50.  Air containing solvent and water vapour expelled from the circulating system passes through a direct contact condenser 72 comprising two layers 78 and 80 of clay rings over the lower, 78, of which calcium chloride solution at -15 DEG  C. flows from a trough 82 to which it is fed via a pipe 106 and a heat-exchanger 98, Fig. 2, through which a refrigerating medium is circulated via pipes 100 and 102 from a refrigerator 96. Calcium chloride solution containing condensed solvent flows from <PICT:0656299/III/1> <PICT:0656299/III/2> the condenser 72 via a pipe 202 to a tank 201, Fig. 2, from which the calcium chloride solution forming the upper layer is normally pumped to the trough 82 via a pipe 208 and the heat-exchanger 98 but at intervals the solvent forming the lower layer is pumped into a solvent and impregnating agent mixing tank 114 via a pipe 206.  The condenser 72 communicates with a container 86 having a vent 90 open to the atmosphere, and containing clay rings 94 fed with calcium chloride solution via the pipe 106 whereby remaining solvent vapours are condensed.  When air expelled from the circulation system becomes more saturated with vapours a valve 62 is opened and valves 64 and 60 closed, some air thus flowing to a surface condenser 32 fed with water via pipes 34 and 36. Condensate flows via a pipe 186 to a container 188, Fig. 2, from which solvent is led out via pipes 192, 194 and 196 to the tank 114.  After some time a valve 60 is opened so that part of the circulating air is first pre-cooled in condenser 32 and then passed to condenser 72.  When the solvent recovery period is ended the basket 12 is lifted, the passages through condenser 32 and conduits 56 closed and fresh air forced through the units 20.

Title: Improvements relating to timepieces
IPC: G04B1/22
Filed: 1930-08-20
Abstract: 361,003. Timepieces. JACCARD, P. R., 12, Rue du Port, Geneva, Switzerland. Aug. 20, 1930, No. 24961. Convention date, Aug. 20, 1929. [Class 139.] Driving mechanism, spring.-Clockwork mechanism in which the escapement is driven from the mainspring through auxiliary springs, the latter being maintained at a substantially constant tension, is characterized by two rotary members, one (z) driven from the mainspring c and the other (k) driving the escapement, relative movement between these two members being used to prevent overstressing of the auxiliary springs 5,6. Mainspring c drives train d, e, g, h, shaft j, cross piece z (rigid with shaft j) and L-shaped levers v, w which are pivoted at x, y respectively to the piece z. Teeth 9 on these levers engage two depressions 4 on a collar 3 rigid with wheel k, which latter is loose on shaft j and drives the escapement through wheel l. The auxiliary springs 5, 6 are stretched from pins 7 on the levers v, w to pins 8 on the wheel k. The spring c, through the train d, e, g, i, m, n, drives a wheel o, loose on shaft and rigid with a plate p. The latter has pins s passing through holes of equal diameter in a second plate r which coacts with the free ends of levers v, w. Assuming spring c is wound up, the shaft (which rotates faster than wheel k) rotates levers v, w bodily, stressing springs 5, 6, until pins 9 ride out of depressions 4. This latter action rotates levers v, w about their pivots so that their free ends are pressed hard against plate r. Plates p, r are rotated from spring c faster than levers v, w so that the system is immobilized until, springs 5, 6 driving wheel k, the pins 9 again reach the bottoms of depressions 4 and release the brake so that springs 5, 6 may be restressed. Spring c may be powerful enough to drive the clock for 8, 15, 30, or 360 days. In a modification, the relative movements of a floating system similar to the above, are used to apply cam-actuated brake segments to the inside of a brake drum.

Title: A process for coating titanium surfaces
IPC: C25B11/04
Filed: 1964-06-16
Abstract: Elements of or coated with titanium or a titanium-base alloy are pickled with a mixture of hydrochloric and nitric acids, washed, dried, coated with a metal of the platinum group and, after washing and drying if necessary, are finally heated in air to a temperature between 150 and 300 DEG C. Typically a graphite rod sheathed in Ti is degreased in trichloroethylene, pickled in a boiling 2:1 by volume mixture of 35%, HC1 and conc. HNO3, washed and dried, electroplated with Pt to give a coating of 20mg/dm2, washed and dried at 110 DEG C. and finally annealed for 2 hours at 250 DEG C. in air.  The electroplating bath is of the chloroplatinic acid type containing also diammonium and disodium orthophosphates, boric acid, sodium hydroxide, and hydrofluoric and orthophosphoric acids and ammonia and is of pH 4.5.  Reference is also made to depositing the platinum group metal by vacuum metallizing or chemical plating and to repeating the steps of depositing the metal and annealing one or more times using electrolysis or these processes in any combination. Platinized titanium coated graphite electrodes prepared as described above with a copper connection made into the graphite may be used as anodes in electrolytic production of sodium chlorate and platinized perforated titanium anodes similarly prepared may be used in winning cobalt from a cobalt chloride solution.

Abstract: 277,983. Perelis, W. J. Sept. 23, 1926, [Convention date]. Grant of Patent opposed. Hydrocarbons, cracking. - In a process for cracking oils of the tube and drum type the oil while at cracking temperature is agitated either by passing it through a tubular cooling apparatus under conditions of turbulent flow or by mechanical agitation. The raw material is deprived of its volatile fractions by passage through heat exchangers 20, 16 and then flows to a container 33 from which it is pumped by a pump Z through cracking coils 61, 71. 81, the temperature being kept lower in the coil 71 than the coils 61, 81 with corresponding variation of pressure. The products from the coil 81 are passed under turbulent flow through a coil 10 in which the temperature is reduced, while being kept in the cracking range, into an insulated reaction drum 11. The vapours produced in the drum 11 are led through a pipe 12, a heat ecxhanger 4, a pipe 13 and a vaporizer 14 into contact with the raw material in heat exchanger 16 and the liquid fraction produced is transferred to the container 33 and retreated as previously described. The vapour fractions are led through a pipe 17 to a rectifier 18 down which is passed a spray of gasoline from a pipe 22 and part of the condensate is recirculated through a pipe 28 and a boiler 44. In the rectifier 18 the products are separated into a vapour fraction which is passed through a pipe 19, a heat exchanger 20, a pipe 24 and a cooler 25 to a storage tank 27, and a liquid fraction collected in a tank 35.
