Title: Process of distilling hydrocarbon oils
IPC: C10G33/06
Filed: 1920-06-07
Abstract: 169,763. Benson, M. June 7, 1920. Hydrocarbons, distilling.-The volatile constituents of crude petroleum or bituminous substances such as oil emulsions, asphalt, tar sands, &c. are separated by mixing the oil &c. with superheated steam or other heated vapour or gas. Oil is pumped from a tank 1 through a meter 4 and valve 5 to a chamber 6 to which steam under pressure from a superheater 7 is passed. The mixture passes through a regulating-valve 12 to an expansion vessel 13 from which the vapours pass to a condenser 16. The steam passed into the chamber 6 may be under a pressure of 100 lb. per sq. in. and at a temperature of 750-1000‹ F. Sulphur dioxide or carbon dioxide may be used in place of steam when reaction with the sulphur compounds is desired, and higher pressures and addition of reagents such as sodium or calcium hydroxide may be used to effect liberation of ammonia or sulphuretted hydrogen.

Title: Liquid-cooled radiant heat treatment of rubber articles
IPC: B29C35/16
Filed: 1951-06-29
Abstract: 699,875. Treating rubber articles by radiant heat. UNITED STATES RUBBER CO. June 29, 1951 [Aug. 16, 1950], No. 15480/51. Class 70 [Also in Group XXXIV] To improve the flexing qualities and re-  sistance to cracking of vulcanized rubber articles having indentations on the outer surface, the article is deformed to stretch the rubber at the bottoms of the indentations which is then softened by the application of radiant heat whilst the main outer surface is protected by a film of cooling liquid. At the conclusion of the heating and after cooling, as by spraying with water, the stretched rubber is released whereby the rubber at the bottoms of the indentations are placed under compression. The invention is shown applied to a pneumatic tyre 10 having circumferential tread grooves 16. The tyre is squeezed to distort the tread, between flanges 11, 12 mounted for rotation on shafts 13, 14. Radiant heaters 17 are disposed around the major circumference of the tyre, the lower portion of which bears on the resilient periphery 22 of a roller 21 rotatably mounted in a trough 25 containing cooling- liquid. Aqueous solutions of organic polymeric substances such as cellulose esters or ethers, methyl cellulose and sodium carboxy methyl cellulose are given as examples of suitable cooling media of sufficient viscosity to prevent run off. U.S.A. Specification 2,110,224 is referred to.

Title: Improvements in or relating to tuned electro-mechanical relays
IPC: H01H51/32
Filed: 1931-05-27
Abstract: 379,346. Electromagnetic relays. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 27, 1931, No. 15554. Convention date, Aug. 15, 1930. [Class 38 (v).] In an electromagnetically operated resonance relay in which a tuned vibrating member, polarized by a permanent magnet, is set into oscillation, usually by superimposed A.C. supplied to the operating winding which may itself be turned to resonate at the operating frequency, in order that the relay may be reasonably economical in operating current and at the same time may reach its full amplitude of vibration within a reasonably short period from the switching-in of the winding, a degree of polarization of the permanent polarizing magnet is chosen such that the steady energizing current occurring on attainment of the normal limiting amplitude of the vibrating member is smaller than one-half to one-third of the switching-in current and is preferably equal to one-fifth of this current, but is not less than one-tenth. The various factors governing the fixing of these limits are fully discussed in the Specification. In obtaining a relay which may operate within the prescribed limits the permanent magnet is replaced by a D.C. electromagnet, the energizing current of which may be varied and the ratio of the switching-in current of the A.C. electromagnet to the current flowing therein during the full vibration of the reed or similar vibrating member is taken with various values of D.C. current. When a suitable value of this ratio within the prescribed limits according to the invention has been obtained, the fieldintensity of the D.C. electromagnet is measured in known manner and a permanent magnet is used which produces the same field intensity. Alternatively the required polarization strength may be obtained by calculation. The vibrating member may be arranged to operate a pivoted hammer fitted with a switch contact when current of the prescribed frequency is supplied to the operating electromagnet.

Abstract: 667,689. Rubber springs. COOK, C. A. (Riv-Officine di Villar Perosa Soc. per Azioni). June 10, 1949, No. 15557/49. Class 108 (iii). In a spring of rubber or the like, comprising an inner rigid sleeve of conoidal shape, an outer rigid sleeve of conoidal shape and a rubber or the like sleeve forced and incapable of sliding between the rigid sleeves, the rubber sleeve is subjected under load to compression and rolling on the surfaces of the rigid sleeves, a disc being fixed to the inner rigid sleeve so as to exert on the rubber sleeve a predetermined pre-stressing and the disc being removed from the rubber sleeve when the load rises above the prestressing value. In the arrangement shown. in which a rubber sleeve 3 is radially compressed between substantially frustoconically shaped outer and inner members 1 and 2, the inner member is provided at one end with a load supporting disc 4 and at the other end with a shaped disc 5 which is adjustable on the member 1 to pre-stress the rubber sleeve 3. Deformation of the sleeve 3 under loads exceeding the pre-stressing value, increases until under extreme loads, the disc 4 comes into contact with the sleeve 3. Two or more supports acting in series or in parallel may be employed in a vehicle suspension.

IPC: C08B3/00
Filed: 1928-05-30
Abstract: 291,360. I. G. Farbenindustrie Akt.- Ges. May 30, 1927, [Convention date]. Cellulose carboxylates. - Cellulose esters of fatty acids are prepared by a process in which ordinary or pre-treated cellulose is treated with a halide of a lower fatty acid in presence of an organic base and an indifferent organic medium, which dissolves, at least partly, the addition product of acid halide and organic base formed in the esterification mixture but is not a solvent for the cellulose ester, which is formed. Halogen aromatic hydrocarbons are particularly suitable for use as the indifferent organic medium. In an example, cotton is added to a mixture of chlorobenzene, pyridine and acetyl chloride. When formation of the cellulose ester is finished, the liquid is decanted from the cellulose acetate and the latter is purified by extracting it with boiling ethanol and then with hot water.

Filed: 1953-06-09
Abstract: 2,4,6-Trinitrochlorobenzene is prepared by nitrating dinitrochlorobenzene with a nitrating agent consisting mainly of nitronium hydrogenpyrosulphate.  With respect to the dinitrochlorobenzene a 100-130 per cent excess of nitrating agent (calculated on the basis of the nitric acid content) is preferably used and preferred working temperatures are 140-170 DEG  C.  The nitrating agent may be added portion-wise to the dinitrochlorobenzene or vice versa, the former method being preferred.  After completion of the reaction the acid phase is separated from the organic phase by known methods, a further amount of 2,4,6-trinitrochlorobenzene being precipitated on diluting the waste acid with water.  The crude product is purified by washing with water and recrystallizing from a mixture of carbon tetrachloride and 4 per cent by volume of chloroform.
