Filed: 1933-02-14
Abstract: 409,863. Distilling zinc etc.; rotary furnaces. KRUPP GRUSONWERK AKT.- GES., F., Buckau, Magdeburg, Germany. Feb. 14,1933, Nos. 4564 and 4565. Convention dates, Oct. 6, 1932 and Nov. 22, 1932. [Class 51 (ii).] Zinc, cadmium, mercury, and other volatile metals are distilled in an annular muffle which is rotated by means of a bearing-shaft within a stationary furnace chamber, the charge being fed continuously and the residue and distillation gases being discharged with exclusion of air. In the apparatus shown the muffle comprises inner and outer shells 12, 13, preferably of nickel or silicon chromium-iron alloy, carried by the hollow shaft 1 around which is an insulating layer 9. Between the two shells are stay members or partitions 16 which completely or partially divide the annular charge space into a number of compartments, and which may be offset relatively to one another to assist in conveying the charge. Feeding is effected from a hopper 22 by a worm 21 through thin copper helical tubes 23, and discharge of the solid residue is similarly effected into a chamber 26, entrance of air being prevented by alternately operated closures. The gaseous products pass through openings 18 into a condenser 6, either fixed, or rotating with the muffle and provided with an air cooling- jacket 29. Heating is effected by a burner 45, Fig. 2, delivering on to actinolite brickwork 47, the combustion chamber being so situated that the gases impinge first on the part of the muffle against which the charge is heaped. After passing round the muffle in the main heating-zone 51 the gases pass laterally to the preheating-zone 49, and thence to the chimney 50. The muffle may be heated by electrical resistances. The gases from the main condenser 6 may pass to an auxiliary condenser 38, Fig. 4, supported by angle irons 39 and having a valve-controlled discharge spiral 42 for the condensed metal. In a modification, (Fig. 5, not shown), the auxiliary condenser is stationary. The main condenser may be formed with open-ended cross tubes to increase the condensation surface and to promote cooling. In a modified construction, Fig. 3 (not shown), the annular muffle is in the form of a tube wound helically around the insulating layer 9 on the shaft 1.

Abstract: 780.160. Indicating liquid levels. SHAND & JURS CO. Feb. 14, 1956 [Feb. 24, 1955], Nn. 4656/50. Class 123(1) An apparatus for measuring the height of liquid in a closed tank of the type employing a metal tape having a weight attached to its lower end and carried by a reel by means of which it can be raised or lowered, further unreeling of the tape being automatically prevented when downward movement of the weight is arrested, comprises a housing 10 mounted on the roof 11 of the tank 12, the upper portion 10a of the housing carrying the reeling means, shown in Fig. 3, for the tape 13. At its lower end the tape carries a solid weight 53. Alternatively, the member 53 may be hollow with small liquid flow and air vent holes whereby it floats temporarily on the liquid surface and then sinks, thereby providing both liquid surface and tank bottom readings. The reeling means includes a reel 16 rotatably carried on a shaft 17 which extends through a gland 19 and carries a crank 21 at its outer end. At its inner end a ratchet wheel 32 is secured to the shaft 17, a spring-loaded pawl 33 carried on the reel 16 engaging with the wheel so that the reel can only be driven in the anti-clockwise direction. The tape 13 is looped over an idler pulley 36 carried on the free end of an arm 37, the arm being pivoted at 39 and urged upwardly by a spring 41 to maintain a desired tape tension during operation. The movements of the arm 37 actuate a friction brake on the reel 16, the brake consisting of a cable 47 passing around the reel, one end being anchored by a pin 49 whilst the other is attached by a spring 51 to the arm 37. In operation, a valve 54 at the lower part of the housing is opened and the crank 21 is turned to lower the weight 53, during which time the arm 37 rests at its lowest position on a stop pin 46. When the weight engages the bottom of the tank, continuing movement of the crank 21 results in the arm 37 being raised by the spring 41 tc apply the brake to the reel 16. The crank can then be rotated in the "lowering" direction without turning the reel due to the pawl and ratchet drive, the tape remaining in a tensioned condition. When the crank is turned to raise the tape, the arm 37 'first drops into engagement with the stop pin 46, releasing the brake and allowing the tape to be raised to the position whereat the liquid level mark can be read through a window 14.

Title: Improved process for the treatment of condensation products of carbamide or its derivatives with formaldehyde
IPC: C08J11/06
Filed: 1925-09-30
Abstract: 266,389. Pollak, F. Oct. 1, 1924, [Convention date]. Condensation products of urea or its derivatives with formaldehyde in the powdered form are converted into homogeneous masses by mixing the powder with the solvents specified in Specification 240,840, in an amount not sufficient to effect dissolution, and submitting the mixture to the combined action of heat and pressure. Instead of the solvents above-mentioned, the viscous soluble initial product of the condensation reaction, which has a swelling action on the hard final products, may be employed. Instead of using mechanical means to effect the preliminary pulverization, the material is dissolved in mineral acids. e.g. by boiling with a 10 per cent solution of hydrochloric, nitric or sulphuric acid, a powdery mass precipitated by cooling, and this powder then subjected to heat and pressure in the presence of a small quantity of the solvent or swelling agent. Specification 202,651 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of solvents and swelling agents in general, and states that the powder obtained by cooling the mineral acid solution may be employed as a filling for liquid urea-formaldehyde condensation products, phenolformaldehyde condensation products, caoutchouc, natural resins, &c.
