Title: Improvements relating to the manufacture of resins from crude benzole and like hydrocarbons
IPC: C08F240/00
Filed: 1943-11-04
Abstract: A process for the production of resins from hydrocarbons listed below, by polymerisation of the unsaturateds therein, which comprises washing the hydrocarbon to remove inhibitors (e.g. phenols and like tar acids) and accelerators (e.g. hydrogen sulphide and mercaptans) naturally present and also tar bases and like discolourers, removing wash oil, creosote and such constituents, if present, by an initial distillation, and submitting it, with or without a further unpolymerised fraction(s) produced in the distillation hereafter referred to in this statement, to prolonged thermal treatment followed or accompanied, or as to a part followed and as to the remaining part accompanied, by distillation of the material, which distillation is continued until a residue is left consisting substantially entirely of polymers of the unsaturateds, the said thermal treatment being effected either in a polymiser or else in a still or partly in one and partly in the other.  The hydrocarbons are crude benzole from coal gas; crude coal tar naphtha from coal gas; light oil from coal gas; crude coal tar naphtha from coal tar or from gas tar oil or from drip <FORM:0574020/IV/1> oil; and light oil from coal tar or from gas tar oil or from drip oil.  These hydrocarbons contain styrene, coumarone, indene or cyclopentadiene.  The flow diagram illustrates the process as applied to a case where the starting material is first submitted to an initial distillation to remove high boiling constituents and at the same time to separate a series of fractions including a solvent naphtha fraction from which commercial xylene is obtained as a principal product along with polystyrene resin, and a heavy naphtha fraction from which coumarone and indene resins are obtained by a two-stage application of the prolonged thermal treatment of the process, first upon the heavy naphtha fraction itself and then upon two sub-fractions, a coumarone sub-fraction and an indene sub-fraction.  The polymerisation which takes place in the prolonged thermal treatment may be assisted by the use of an accelerator such as benzoyl peroxide or sulphuric acid. Specifications 549,516, 550,798 and 557,253 are referred to.

Abstract: 177,757. Da et Dutilh. March 31, 1921, [Convention date]. Current meters; casings and supports. - The defects produced by hysteresis or remanence in electrical measuring instruments of the moving-iron type are diminished by providing one or more electromagnetic compensating - systems having couples acting in opposition to to the main system and comprising a moving-iron mass, the iron of the compensating-system being of such a quality that the current in the main system, acting upon the compensating system produces defects therein which approximately compensate the defects in the main system without greatly reducing the measuring-couple. In addition to the compensating-system in opposition, compensating-couples acting in the same direction as the main couple can be employed, but in all cases the compensating-couples are subject to the same current variations as the main couple. As shown in Fig. 1, the compensating-system comprises a separate coil 7 acting on a vane 6 the size of the coil and magnetic qualities of the vane being determined relatively to the characteristics of the main couple. As shown in Fig. 3, the compensating-system is mounted in the field of the main coil 11 acting on two mutually repellent vanes 9, 10, and comprises two iron members one of which 12 is rotatable with the spindle, the other, 13, being fixed, these two members being mutually attractive.

Filed: 1931-06-29
Abstract: 374,647. Endless chain elevators. DELAMERE, R. D., 18, Hook Avenue, Toronto, Canada. June 29,1931, No. 18790. [Class 78 (i).] An elevator, which is intended particularly for the conveyance of soiled dishes from a restaurant to a washing room, is provided with means for supporting the trays of soiled dishes and delivering them automatically to the lowering members. The elevator consists of two pairs of endless chains 12 which are provided with triangular brackets 13 to support the trays. The pairs of chains pass over sprockets 11 freely mounted on shafts 4, 5 at the top of the apparatus on which are mounted pairs of cams 6. Each cam is formed with a semicircular rim 7 which is stepped radially inward at 8 to meet a smaller concentric portion 9 which is connected with the rim by a tangential portion 10. The interval between the brackets 13 corresponds with the distance the chain travels during one revolution of the shaft 4, and the arrangement is such that the supporting face registers with the step 8 of a cam when the latter is vertical. The chains 12 pass round sprockets 21, 24 at the lower end of the apparatus. A clutch consisting of discs 25, 26 is arranged on the shaft 4. The disc 25 is fast on the shaft and carries a pivoted dog 27 which can be brought into engagement with a notch 261 in the perimeter of the disc 26. The disc 26 is loose on the shaft and is connected to the adjacent sprocket 11 which rotates continuously. The dog 27 is held in the disengaged position by a lug 31 on a pivoted arm 28, but when a tray to be lowered is placed in position on the cams 6, it engages a finger 32 on the arm and swings the latter outwardly. This movement carries the lug clear of the dog which swings inwardly under spring action into contact with the periphery of the disc 26 over which it rides until it engages the notch 261. The notch 26<1> is so located that when the dog 27 enters it, the steps 8 of the cams will be in register with the uppermost of the chain brackets 13. The discs then rotate together through one complete revolution, and the cams 6 turn and deposit the trays on the brackets. The sprockets 11, and the sprockets 21, 24 are connected by chain gearing, and the shaft 34 of the sprocket 21 is driven by a motor 38. The upper end of the apparatus is enclosed by a casing 14 which has a rectangular opening 15 of a size slightly larger than the trays. At the lower end of the apparatus the trays are deposited on an endless belt 41.

Title: Built organic detergent compositions and processes for preparing them
IPC: C11D3/06
Filed: 1951-08-13
Abstract: A detergent composition comprising particles of a detergent core surrounded by a coating of numerous hydrated builder particles, is made by agitating a mixture of solid organic detergent particles with a finely divided anhydrous builder which is capable of forming a hydrate, whilst adding moisture.  The mixing may be effected by tumbling the ingredients in a rotating drum, and a suitable apparatus is described.  The particles which comprise the detergent core may be made by spray or roll drying, spray or roll cooling, framing or grinding.  Suitable detergents include soaps; anionic synthetic detergents such as the sulphate and sulphonate detergents, particularly those having an alkyl group of 8 to 18 carbon atoms, e.g. sodium dodecyl benzene p  sulphonate; cationic synthetic detergents such as those derived from heterocyclic tertiary amines, e.g. from glyoxalidines substituted in the 2-position with an alkyl group of 11-17 carbon atoms and optionally substituted in the 1-position with a lower alkyl or alkylol group, and salts of polyethylene ethers of fatty amines; and non-ionic synthetic detergents.  A number of synthetic detergents are specified. Builders which may be mixed with the detergent in making the core include water-soluble inorganic sulphates, silicates, phosphates, borates and carbonates.  The anhydrous builder used for the coating may be an alkali metal, especially sodium or potassium, salt of a phosphoric acid such as sodium tripolyphosphate, tetrasodium pyrophosphate, disodium dihydrogen pyrophosphate, trisodium orthophosphate, and per-salts.  Supplementary builders which do not themselves form hydrates may be included in the coating composition, such as sodium carboxymethyl cellulose, higher fatty alcohols such as lauryl and cetyl alcohols, higher fatty acid amides such as lauramide and coconut oil fatty acid ethanolamides, corrosion or tarnish inhibitors such as melamine and diethyl thiourea, and fluorescent dyes such as stilbene derivatives.  These builders may be added in powdered or molten form, or sprayed into the mixture as a solution.
