Title: Ethylene and propylene prodn from crude oil - by hydrocracking to produce 2-5C alkane fraction and thermally cracking the alkane fraction
IPC: C10G69/06
Filed: 1976-02-04
Abstract: Ethylene and propylene are produced by (1) hydrocracking a crude oil boiling range 200-1000 degrees F) over a sulphided hydrocracking catalyst (Gp VIII metal and/or Gp. VIB metal and halogen supported on silica-alumina or a symt synthetic or natural gaugasite) at 300-646 degrees C and >400 psig with an H2: oil ratio of 4-50:1 and for 1-180 secs., conditions being so selected that a 2-5C product is obtained in a 91-95% yield and with an n-paraffin isoparaffin ratio of >3:1, (2) separating the hydrocracking effluent to recover a 2-5C alkane product, and (3) thermally cracking the 2-5C alkane fraction to produce ethylene and propylene as co-products. Olefin yields of 50-60 lbs/100 lbs feed are obtained (c.f. 30-35 lbs. by the thermal cracking of gas oils). The 2-5C product with its high (3-6 1) n-paraffin ratio can be used as a replacement for l.p.g. as a feedstock for existing ethylene plants.

Title: Forming coloured embossed patterns on fabric - by passage with dye coated web through roll nip including an embossed roll
IPC: D06C23/04
Filed: 1976-03-29
Abstract: A textile fabric is embossed to produce a profiled pattern and is simultaneously printed to produce a coloured pattern by being fed with a transfer sheet through e.g. a nip including an embossing roll and a presser roll. The transfer sheet is coated with an evaporable or sublimable dye which under heat (e.g. 180-260 degrees C) is transferred onto the textile fabric as they pass together through the nip. A variety of coloured embossed patterns on a textile fabric (e.g. synthetic) can be easily produced. The method is used partic. for printing, acrylic, polyester or tri-acetate fabrics, but may be also used for fabrics of natural fibre.

Title: Isolating paraffin sulphonic acids from sulphonation mixt. - by adding specified solvent, sepg. aq. phase, then evaporating to obtain prod. useful as biodegradable detergent
Inventor: BOY ARISTIDE
IPC: C07C303/46
Filed: 1976-10-15
Abstract: A process for sepg. paraffin sulphonic acids contained in a sulphonic soln. with sulphuric acid, water and opt. non-sulphonated paraffins is provided. A weakly polar organic solvent is added to form an organic phase contg. all the sulphonic acids and an aq. phase contg. almost all the sulphuric acid. The organic solvent is an aliphatic and/or cycloaliphatic ether, ketone, ester or ketoester of >=5C atoms, the solvent forms an azeotrope with water and has a water solubility 7%. The aq. phase is sepd. The organic phase is neutralised evapd. to remove volatiles to recover the molten sulphonates which are then opc. converted to a powder. The prods. are biologically degradable detergents. Compared with a previous process using a weakly polar alcohol as solvent, the above solvents have the advantage of a greater volatility, and ensure all the sulphonic acid is in the solvent phase. The process enables a practically anhydrous sulphonic acid to be isolated, easily converted to a non-caking powder.

Title: Thin, porous, flexible coating for sports grounds - partic. tennis courts, applied over porous concrete or asphalt surfaces
IPC: E01C13/06
Filed: 1977-05-16
Abstract: Coating is made by first applying over the base surface an adhesive coating consisting of a resinous binding agent (A) which sticks both to porous concrete and to elastic granulated material. The coating has a viscosity of 50-220 seconds (Ford no. 4 cup) at the moment of application. Before the binding agent sets a thin layer of elastic granules (B) (the min. size of which is > the max. dia. of the substrate pores) is spread over the coating. After the binding agent sets the loose granules are removed, giving an even, thin, pref. single thickness, granule layer. A new layer of binding agent (A) is then applied. Before it sets an elastic granulated material of granule size pref.  that of (B) is spread over the layer. After setting of the binding agent, the loose excess granules are removed. The coating lessens the hardness of the porous concrete or asphalt surface. It also provides a surface on which a tennis ball has good impact and bounce properties.
