Title: Process of and apparatus for the production of foils and like planiform structures from formylcellulose
IPC: C08L1/00
Filed: 1935-06-14
Abstract: <PICT:0439793/IV/1> Foils and like structures are produced by pouring a formyl cellulose reaction mass containing formic acid, dehydration medium, and formyl cellulose) on to a suitable support, evaporating wholly or partially the formic acid in the mass, and then precipitating in water.  If desired, plasticizers such as ethyl acetanilide, camphor, and dibutyl phthalate may be added to the formylating mass before pouring.  Foils which cannot assume an electric charge are produced when a formyl cellulose containing free hydroxyl groups is employed, e.g. formyl cellulose containing 40--45 per cent of formic acid.  In an example, a formyl cellulose reaction mass obtained by treating cotton linters or pulp with formic acid in the presence of zinc chloride, is ripened and de-aerated.  It is then poured from a vessel 1 into a pourer 3, and the film which forms on the runner belt 6 is led over a number of heating pipes 8.  A current of air enters the chamber at 9 and leaves at 10.  The belt 6 carries the partially (e.g. 75 per cent) dried film through the coagulation bath 11 consisting of water and of formic acid and zinc chloride taken up from the film, and finally the film which is detached from the belt by means of a roller 14, is passed through a series of washing and plasticizing baths 18, 19, 20, and over drying rollers 21.  Formic acid and zinc chloride are recovered from the coagulating bath which preferably is caused to move in counter-current direction to the film.
Patent GB-1104682-A (GB)
Title: Improvements in or relating to textile opening and drafting and machines therefor
IPC: D01H5/24
Filed: 1964-04-25
Abstract: A sliver is opened and drafted by a pair of intermeshing rollers which are covered by spaced rings of teeth arranged so that each ring on one roller extends between adjacent rings on the other roller, with one roller being rotated at a surface speed substantially greater than the other.  As described a pair of feed rollers feed the sliver onto the surface of the slower roller whose teeth are inclined outwardly in the direction opposite to the direction of rotation so that the faster roller whose teeth are inclined outwardly in the direction of rotation causes the sliver at the start of the zone of co-operation between the rollers to be pressed into the teeth of the slower roller and at the end of the zone of co-operation to be combed out of that roller - the sliver being drafted by the rollers in the zone.  The sliver may be removed from the faster roll by a further roller similar to the slower roll and rotating faster than the faster roller and may be subjected to one or more further drafting and opening steps.  At the output end of the machine there is a pair of plain-surfaced draw-off rollers which may be the intake rollers of a spinning frame or may deliver the sliver to a bobbin winding arrangement.

Title: Improvements in and relating to Electrical Discharge Tubes.
IPC: H01T1/12
Filed: 1916-12-07
Abstract: 110,057. British Thomson-Houston Co., (General Electric Co.). Dec. 7, 1916. Relays.-A discharge tube capable of use in an electric surge indicator has electrodes at a short distance apart, say, “mm. to 1 mm., in a gas which is kept pure by a substance such as calcium, magnesium, or alloys thereof, reacting with nitrogen, oxygen, water vapour and hydrogen. One electrode, preferably the cathode 1, may be made of such a substance, the other electrode 2 being a rod of tungsten, or molybdenum; or both may be of the reactive substance. The anode should not be larger than the cathode, and is preferably smaller, as shown. Both are preferably pointed. A rare atmospheric gas such as argon or neon, at a pressure of 20-40 cm. of mercury, is a suitable filling. Initially, the gas is purified by repeatedly passing a high-pressure current. In the use of the tube, a high-pressure discharge of about a micro-ampere, caused for instance by excessive pressure in a main 7, renders the tube conductive for a low-pressure current from mains 12. This current may excite an electromagnet 15, which operates a recorder or indicator such as a bell 18 and temporarily breaks the low pressure circuit. Between the high.pressure main 7 and the tube are a spark-gap 8, an insulator 9 having capacity, and a smaller gap 10. An earthed condenser 11 protects the low-pressure circuit. Specification 7997/15, [Class 39 (i), Electric lamps, Arc &c.], is referred to.

Title: Improvements in or relating to the lead sulphide sweetening of petroleum distillates
IPC: C10G19/06
Filed: 1950-07-19
Abstract: Sodium sulphonates are prepared by sulphonating the fraction of a sulphur dioxide extract of kerosene boiling between 400 DEG  and 530 DEG  F. in the presence of a low viscosity oil inert to 98 per cent sulphuric acid and neutralizing the product.  Suitable diluent oils include heavy kerosene or a spray oil of S.U.S. viscosity 300 at 210 DEG  F., and it may be used in amounts of about 6 volumes to 10 volumes of distillate.  The sulphonation is carried out at about 120 DEG  to 130 DEG  F., the temperature being maintained within this range by cooling or by addition of further low viscosity oil.  After sulphonation is complete, water is added, the weak acid layer drawn off and caustic soda solution is added to the oil to form the sodium salt.  The unsulphonated oil separates and is removed and sodium sulphate precipitated from the aqueous layer by cooling.ALSO:<PICT:0691934/III/1> To the lead sulphide reagent used for sweetening petroleum distillates there is added a minor proportion, sufficient to inhibit emulsion formation, of sodium sulphonates prepared by sulphonating that fraction of a sulphur dioxide extract of kerosene which boils between 400 DEG  and 530 DEG F, and neutralizing the sulphonated product with caustic soda.  The amount added lies between 0.15 and 1.5 per cent by weight. Preferably part of the sweetened product may be recycled to the treater to reduce the total mercaptan content of the mixture of fresh feed and sweetened product to below about 0.02 per cent by weight. As shown in the flow diagram caustic soda solution is introduced into the mixing tank 3 through line 2, lead oxide through line 4 and the sodium sulphonates through line 5.  The mixture so formed is pumped into line 7.  A sodium sulphide solution is prepared in tank 10 and passed through lines 11-12 into the blowcase 13, from which it is expelled by air into line 7.  The feed (a petroleum distillate) is introduced through line 16 and the mixture of feed and treating reagent is pumped to the loop mixer 19 and thence to the treater 20. Air to keep the solution in balance is added to line 18 through line 21.  The overflow from the treater (feed and trdating agent) flows through line 22 into the inclined settler 23, when separation of the phases is completed.  The treated distillate is withdrawn through line 24 and passed through a rock-packed coagulator 25 to remove final traces of lead sulphide.  The sweetened product is withdrawn through line 26.  Treating agent settling out in 20, 23 and 25 is returned to line 7 through lines 27, 28 and 29.  Try cocks are provided in the treater, settler and coagulator and liquids so withdrawn may be run through lines 31, 32 and 33 into the sump, or returned to the treater 20 or mixing tank 3.  In order to keep the total mercaptan content of the liquid in the treater below 0.02 per cent by weight, line 39 is provided for the return of sweetened product to the feed.  If desired, sodium sulphide may be passed directly into the treater or settler through line 38.
