Title: Non-woven fabric
IPC: D04H3/14
Filed: 1970-03-20
Abstract: 1284236 Non woven fabric MONSANTO CO 20 March 1970 [21 March 1969 22 July 1969] 13553/70 Addition to 1248232 Heading D1R A non woven fabric comprises a web of continuous polyamide filaments which have been autogenously bonded together by an activating gas selected from HCl, HBr, HF, SO 3  and Cl 2  by the formation of intermolecular hydrogen bonds between-NHCO-linkages in different filaments, the web weighing less than 34g/m<SP>2</SP>. The activating gas can be applied to the filaments by mixing it with the air used to attenuate the filaments during air laying thereof to form the web, or the gas can be passed through an already air laid web. In the latter case the web can be bonded prior to exposure to the activating gas by applying a solution of nylon to the air laid web to deposit nylon ligaments therein. The activating gas can be removed by passing the web through an alkaline bath. The filaments may be nylon 6, 66 or 10. The filaments may be arranged preferentially in one direction.

Patent GB-496124-A (GB)
Title: A process for the manufacture of a purified hard resin from lac or shellac
IPC: C09F1/00
Filed: 1937-05-19
Abstract: Lac or shellac which has been cleaned, is subjected to the extracting action of an aqueous alkaline medium under such conditions that only a minor proportion of the total lac matter becomes dissolved or dispersed, and the remaining undissolved or undispersed lac matter, which constitutes a relatively hard resin, is separated from the solution or dispersion.  Treatment temperatures of 40-95 DEG  C. are mentioned.  It is unnecessary to remove more than about 18 per cent of the lac used as starting material.  Specified alkalies which may be used are sodium carbonate, ammonium carbonate, sodium di-phosphate, sodium sesquicarbonate, potassium bicarbonate, borax and trimethylamine, and the alkaline solutions used are generally very dilute.  Two or more alkalies may be used together, and a wetting agent, such as a sulphonated oil, sulphonated oxy-acid, sulphonated fatty alcohol, sodium sulpho-ricinoleate or triethanolamine, may be added.  Some wetting agents, such as mono- or triethanolamine, which have a fairly strong alkaline reaction, can function at the same time as both extracting agent and wetting agent. The hard lac fraction may be washed and bleached, and the dissolved or dispersed soft lac fraction may be freed from wax and recovered by precipitation with a mineral acid.  Specification 175,023, [Class 95], is referred to.

Title: An improved method for the production of combustible gases from liquid fuels
IPC: C10G9/00
Filed: 1951-06-18
Abstract: 687,766. Generating oil gas. KOPPERS GES., H. June 18, 1951 [June 17, 1950], No. 14424/51. Class 55 (ii). In a process for making combustible gas, which may be used as towns gas, from liquid fuels such as mineral oil, coal tar oil, distillation residues &c. the fuel is first divided by heating into a vaporous and a liquid portion, the liquid portion then being partially combusted with oxygen or oxygen-enriched air to produce combustible gas at a high temperature, whilst the vaporous portion is injected into this gas to undergo cracking. The apparatus consists of two parts, a lined reaction chamber 1 and an oil heater and vaporizer 2. The chamber 1 is provided with ports 4 containing nozzles 5 through which a mixture of hot oil from pipe 7 and oxygen or oxygenenriched air from pipe 6 is injected into the chamber. Steam may also be injected, with the oil-oxygen mixture. The oil ignites and the combustion gases, consisting largely of carbon monoxide and hydrogen, pass up through the chamber to meet a stream o oil vapour injected through nozzles 8. Hydrocarbon gases such as natural gas may be injected with the vapour. The vapour is cracked by the high temperature to form permanent gas which, admixed with the products of the partial combustion of the liquid oil, discharge through an outlet 10. The oil pretreatment apparatus consists of a kettle 13 traversed by tubes 15 through which pass the hot gases generated by a burner 14. Oil is filled into the kettle toa level 20 and, in operation, oil vapour collects in a space 21 whence it is led by a pipe 9 to the nozzles 8. Hot liquid oil is withdrawn by the pipe 7 to feed the nozzles. 5. The calorific value and specific gravity of the generated gas is controlled by adjusting the proportion of liquid oil to oil vapour by regulation of the burner 14 and by recirculation of a part of the waste gas through a pipe 22.

Filed: 1947-06-04
Abstract: 647,891. Spinning machines. SCRAGG & SONS, Ltd., E., and DAVENPORT, A. June 4, 1947, No. 14740. [Class 120(ii)] In "uptwisting" spinning machines for silk or artificial silk the yarn is wound on to cones instead of bobbins, and in order to compensate for the conical form, the cones are driven at a fluctuating speed to maintain a steady tension on the yarn, by the gearing shown. The machine drive is via wheel 22 on to shaft 21 and thence via gears 18 and 16 and sprocket wheels 15, 13, 8 and 6 and their connecting chains to the roller shaft 7. In addition to the straight drive, wheel 16 is made to roll around wheel 18 by means of the pinion 20, wheel 12, eccentric 11 and arms 10 and 17, at the end of the link 19. This rolling action increases or decreases, according to the direction of the roll, the rotational speed of the wheel 16 and thus imparts a fluctuating rotational speed to the roller shaft 7 which drives the cones.
