Title: Improvements in means for treating the exhaust gases of internal combustion engines
IPC: F01N13/10
Filed: 1933-11-18
Abstract: 413,744. Purifying exhaust gases. LANGTON, H. M., 26, Devonshire Terrace, Bayswater, London, LUSH, E. J., The Laboratory, Powder Mill Lane, Dartford, Kent, and WATSON, G. P., Sandybank, Banks Road, Sandbanks, Bournemouth. Nov. 18, 1933, No. 15309/32. [Class 7 (ii).] Exhaust gases with or without the admixture of air are passed first over or through one or more catalysts reactive at high temperatures, such as metallic vanadates or molybdates and afterwards over one or more catalysts reactive at low temperatures, such as iron oxide with chromium oxide as a promoter, copper and manganese oxides promoted with cerium oxide or with cobalt and silver oxides or with one or more of the rare earths. The exhaust gases enter a manifold 1 through apertures 2 and pass through partitions 7 supporting the high temperature catalyst, into an exhaust pipe 3, at the end of which is a valve 5. When the velocity of the gases is low the valve is closed and the gases pass through perforations in the pipe 3 into a chamber 4 housing asbestos mats 8 which carry the low temperature catalyst. As the speed of the exhaust gases rises, the valve opens and allows them to enter a pipe 6 without passing through the chamber 4 and the low temperature catalyst. Air may be admitted to the pipe 3 either by the injector action of the gases, by the motion of a vehicle, or by a pump ; or the air may enter through a spring-loaded valve 9. The gases may be filtered before contact with the catalysts. The Specification enumerates the proportions by weight of suitable catalysts and refers to Specification 411,377.

Abstract: 599,625. Aerial coupling arrangements. STANDARD TELEPHONES & CABLES, Ltd. June 15, 1945, No. 15336. Convention date, June 27, 1944. [Class 40 (v)] In an arrangement in which a transmitter 1 and receiver 2 are connected to a common aerial 3 by branch transmission lines 4, 5, respectively, a protective network 8 is placed in the receiver line 5. The network 8 comprises a pair of stub lines 9, 10 short-circuited at the ends 13, 14 and open at the ends 15, 16, at which spark-gaps or gasdischarge devices 17, 18 are located. In order that the network 8 should be effective over a frequency band, the line 5 is connected to intermediate points in the studs 9, 10, the length of each stub and the spacing between them along the line 5 being made a quarter-wavelength at the midband frequency. Alternatively, one stub may be resonated at the frequency of one end of the band, and the second stub at the other end. The length of the line 5 from the stub 9 to the junction A with the line 4 is also a quarter-wave at mid-band frequency. An open-circuited quarter-wave stub 7 terminating in a discharge device 7<1> is connected to the transmitter line 4 at a point a quarter-wave length at mid-band frequency from the junction A in order to reject received signals from the branch 4. During transmission a blocking circuit 19 under the control of the transmitter 1 renders the receiver 2 inoperative.

Filed: 1940-10-25
Abstract: 544,782. Making twist drills &c. HURSCH. MAN, A. Oct. 25, 1940, No. 15697. [Classes 83 (ii) and 83 (iv)] Forging dies.-In an apparatus for forming twist drills or other helical shapes, the work is forged between upper and lower die blocks 1, having die bars extending angularly across each semicylindrical channel each die bar having a smaller sectional area at the initial contacting end than at its finishing end. The channels 3 of the upper and lower die blocks at the receiving end (top of Fig. 1) are of true cylindrical form at the centre part 4 with slight relief at the sides 5 and 6. Within each channel is located an unsymmetrical die bar 7 which may either be integral with the die block, Fig. 1, or formed on an insertable separate member 8, Fig. 13, which is located above a knock out opening 10. With the latter construction variations in pitch and size of flute may be provided for by using different inserts. The drills formed have elevated land portions 12 and clearance land areas 13 intermediate the flutes 14, 15. Different finished sizes may be produced from the same dies by varying the degree of grinding or machining of the portions 12. The clearance lands are formed by parts 21 of the dies of uniform height. The part elliptical shape produced by the relieved parts 5, 6 at the entering end are reduced to true cylindrical shape by the parts 21, the work tending to feed itself forward automatically. The centre section of the die bar is almost symmetrical, Fig. 7. The clearance forming section then gradually widens and the extension land enters the free space 27.

Filed: 1943-09-27
Abstract: 576,588. Hydrolising titanium chloride solutions. BRITISH TITAN PRODUCTS CO., Ltd. Sept 27, 1943, No. 15838. Convention date, Sept 25, 1942. [Class 1 (iii)] In the hydrolysis of a titanium tetrachloride solution by introducing a comparatively concentrated solution thereof into a volume of hot or boiling water at a slow rate to form colloidal nuclei which serve as seed during the hydrolysis under heat, the concentration of the chloride solution and the ratio of solution to water are such as to yield after hydrolysis a constant boiling hydrochloric acid. Using a solution containg 290 grams per litre of titanium calculated as TiO2 the ratio of solution to water is substantially 1:1. The solution may be added to the water at a uniform rate over a period of 10 minutes to one hour, or a part, say one-fifth may be added in five minutes, and the balance then be added over a period of five to ten minutes. The solution may be at a temperature of 25-65‹C., and the water is preferably maintained at or near 100‹C. during the addition. Rutile pigments are obtained by calcining at 800‹C. the washed precipitated titanium dioxide. Specification 550,995 is referred to. The Specification as open to inspection under Sect. 91, is not limited to carrying out the process under conditions detailed above, but only to the correlation of the solution concentration and its rate of addition to water to ensure seeding during the hydrolysis.

Title: Method of producing activated charcoal
IPC: C01B32/336
Filed: 1936-06-06
Abstract: In a process for the activation of carbon by means of gases, the carbonized substance in granular form is rapidly and repeatedly passed through the same activation furnaces or through a series of such furnaces which may be different in character in order to effect a gradual activation of the whole mass which undergoes each time only a partial activation, the operation being repeated as many times as is necessary to complete the activation, and the mass being suddenly cooled after each passage through a furnace.  The formation of fissures in the grains may be assisted and excessive oxidation prevented by wetting the carbon during or after each cooling operation, either with water or a saline solution, which may be obtained by washing previously activated carbon.  The process may be applied to all forms of carbonized substances, including substances which have been carbonized in the presence of activating chemical agents.
