Filed: 1932-03-10
Abstract: 384,505. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. March 10, 1932, No. 7200. Convention date, May 29, 1931. [Class 38 (v).] In an " expansion " switch provided with a condensing chamber connected with the switch chamber so as to condense the expelled vapour and return it to the liquid-filled switch chamber, the condensing chamber is provided with large outlet openings normally closed by spring pressure and opened only when the pressure exceeds a certain value. In the arrangement shown in Fig. 1, the switch chamber 10 containing the liquid-immersed fixed contact 12 is contained within and is integral with the condensing chamber 11 in which exhaust tubes 25, 26 are located communicating with the outer air. The switch chamber and the condensing chamber have covers 17, 19 held down by spring bolts. When small loads are disconnected at the switch, the cover 17 rises and sufficient expansion is obtained through the exhaust pipes 25, 26. When heavier loads are dealt with, the resulting vapour pressure lifts the cover 19 to permit of rapid expansion. In the construction shown in Fig. 2, the switch chamber consists of the inner chamber 30 and the superimposed verticallymovable guided plates 31 to 34. In the normal position of the parts, the plates are pressed together on to the switch chamber proper by the spring-urged cover 43 of the condenser chamber through a tube 37 mounted on the cover. This tube has large orifices 38, 39 at its lower and upper ends. A cylindrical sleeve 50 is arranged around and spaced from the plates 31 to 34, and the under surface of the upper wall of the condensing chamber is domed, as shown, to form a hollow ring. Outlets 53 communicate with an outer container. In this construction, pressure relief is afforded simultaneously at both the switch chamber and the condensing chamber. The vapour from the switch chamber pushes forwards the liquid between the tube 37 and the sleeve 50 in the form of a liquid piston and this liquid is guided by the domed upper wall into the outer part of the outer vessel. The vapour passes inwardly through the passages 38 up the tube 37 and outwardly through the passages 39 to atmosphere, the cover having been raised through the intermediary of the plates and the tube 37 by the vapour pressure. The circuitous path taken by the vapour stream assists condensation.

W., c /o British Celanese, Ltd., Spondon, near Derby. March 10, 1933, No. 7304. [Classes 120 (ii) and 120 (iii).] A number of yarns continuously with their treatment are assembled as a narrow ribbon and traversed in that form on a winding package, and during a subsequent unwinding operation the ribbon is divided into a number of ends which constitute individual yarns for further treatment and use. A number of separate threads are led from a stretching apparatus or other suitable source of supply through the teeth 9 of a comb or reed 10 mounted on a traverse bar 11, and are traversed as a flat ribbon on the bobbin 7 driven on by a driving drum 8 contacting with the yarn or the bobbin 7. The teeth 9 of the comb are held between two rods of stainless metal 12, the upper ends of the teeth being covered by a bent sheet metal cover 13. The comb is carried on a rod 15 held in a bracket 16 by a nut 17 so that the comb may be set at an angle to condense the yarns to a narrow band. Thus a ribbon of 5 or 6 ends may be #" or <9>/32" wide. The bracket 16 is carried on a screw 18 having a milled head 19 and milled nut 20 to permit the position of the comb on the traverse bar to be adjusted accurately. On unwinding the threads are separated by passage through a comb and may be twisted separately or doubled in any desired manner. Specifications 371,461 and 413,025 are referred to.
Patent GB-217323-A (GB)
Title: Manufacture of a white pigment
IPC: C09C1/00
Filed: 1923-03-14
Abstract: White pigments containing zirconium oxide and one or more alkaline earth sulphates are obtained by precipitating together zirconium oxide or basic sulphate and alkaline earth sulphate, and calcining the mixture.  Zirconium sulphate solution containing a greater proportion of ZrO2 than corresponds with the formula Zr(SO4)2 or a mixture of zirconium sulphate and chloride may be treated with an alkaline earth salt. Zirconium sulphate is obtained by partial extraction of a zirconium ore with sulphuric acid, for instance by heating with the acid and dissolving the solidified mass with water. The residue, mixed if desired with fresh ore, is heated with an alkaline earth salt.  Zirconium sulphate is obtained by partial extraction of a zirconium ore with sulphuric acid, for instance by heating with the acid and dissolving the solidified mass with water. The residue, mixed if desired with fresh ore, is heated with an alkaline earth compound such as barium carbonate or a mixture of barium sulphate and carbon and a small proportion of a flux and the product containing the zirconate is dissolved in an acid such as hydrochloric acid.  The solutions of chloride and sulphate are mixed in such proportions that the whole of the sulphate radical is precipitated by the alkaline earth chloride present.  Barium carbonate is then added to precipitate the remainder of the zirconium, and the total precipitate is separated, dried and calcined, preferably at 1000 DEG  C.  The iron present is converted into the ferrous state by adding sulphurous acid or a sulphite.  In another example, solutions of zirconium chloride and sulphate are mixed and barium chloride is added in such quantity that the zirconium and sulphate radical remaining in solution are in the proportion 5Zr :3SO4.  Much of the zirconium is precipitated as a basic sulphate and the remainder precipitates on boiling.  If calcium replaces barium in this example, the precipitation does not occur until the solution is boiled.  In another example, a solution of zirconium sulphate containing about 2 per cent ZrO2 is boiled, cooled, and mixed with barium chloride so that after allowing for the formation of barium sulphate the ratio of Zr to SO4 in the mixture is 5 Zr; 3 SO4.  Practically all the zirconium precipitates without boiling.  A product containing less Ba SO4 can be obtained by treating a zirconium solution with lime so as to remove half the SO4, leaving ZrO.SO4 in solution, which is then treated as in the last example.

IPC: B07C5/20
Filed: 1916-05-26
Abstract: 101,455. Fabrik von Maggi's Nahrungsmitteln. Nov. 12, 1915, [Convention date]. Sorting by weighing.-In a machine for auto. matically sorting articles by weighing, a conveyer band 1, Fig. 1, carries each article to a position 3 against an abutment 4. A U-shaped gripper 5 reciprocated on a rail 7 then moves the article on to a scale-pan 9, and a power-driven cam 21, Fig. 2, allows a slide 12 to advance under the influence of a spring 11, the gripper being automatically lifted clear of the article by suitable known mechanism and then returned to the conveyer band to engage the next article. If the article is under weight, a finger 13 on the slide abuts against a resilient pin 14 on the scale-pan, and the article remains on the pan. If, however, the article ie of sufficient weight, the slide 12 passes over the pan and pushes the article into the position 19 in front of a channel 18. The next feed movement of the gripper pushes the article into either the channel 17 or 18 according to its predetermined position, a tail 5<e> on the gripper holding back the succeeding article on the conveyer band until the return of the gripper.

Abstract: 1,058,384. Guanidinoarylcarboxylic acids and their halides. MERCK & CO. Inc. June 11, 1964 [June 14, 1963], No. 7518/66. Divided out of 1,058,383. Heading C2C. The invention comprises compounds having the general formula R.CO.X, wherein X is a halogen atom or a hydroxy radical and R is a guanidinoaryl, guanidinomethylaryl, guanidinoaralkyl, guanidinoaryloxyalkyl, guanidinomethylaralkyl, guanidinomethylaryloxyalkyl, guanidinoarylisoxatolyl or guanidinomethylarylisoxazolyl radical, and salts thereof. The free acids are prepared by the following processes: (i) forming the guanidino group from an amino group in the corresponding amino-carboxylic acid by contacting the latter with smethyl-isothionitrourea to give as an intermediate product the corresponding nitroguanidinocarboxylic acid which is then catalytically hydrogenated; (ii) when R is a guanidinoaryl, guanidiuraralkyl, guanidinoarylisoxazolyl or guanidinomethylarylisoxazolyl radical, intimately contacting the corresponding aminocarboxylic acid with benzoyl cyanamide and hydrolysing the resulting product; (iii) when R is a guanidinomethylaryl or guanidinomethylaralkyl radical, reacting the corresponding amino-carboxylic acid with o-methyl-isourea in alkaline solution. The acid halides are obtained from the free acids by conventional procedures. In the above processes the product is generally obtained initially in the form of an acid addition salt but this can be converted to the free guanidino acid by adjustment of the pH.
