Title: Method of shrinking fabric or paper
IPC: B31F1/18
Filed: 1973-04-18
Abstract: 1396811 Shrinking fabric and paper I HOJYO 18 April 1973 [13 Dec 1972] 18841/73 Headings D1S and D2A A web of sheet material 8, e.g. fabric or paper, is shrunk by (a) continuously driving, with driving roller means 2, an endless elastically-extensible rubber belt 1, the thickness of which is reduced when the belt is stretched, (b) providing first and scond rollers 6, 7 on opposite sides of the driving roller means 2; (c) gripping the belt 1 at two points D, G between the rollers 6, 7 and the means 2; (d) stretching one portion of the belt 1 located between the points D, G to give it a reduced thickness over that portion; (e) placing the sheet material 8 on the stretched portion of the belt 1 and transporting it to the point D together with the stretched belt portion; (f) causing the belt 1 to contact suddenly immediately after passing the point D by releasing the tension in the belt whereby the sheet material 8 supported on the belt surface shrinks by an amount substantially equal to the contraction of the belt; and (g) heating the sheet material 8 to permanently set its shrunken form. In one embodiment, Fig 1, the belt 1 extends around rollers 2, 3, 5 of which the roller 2 is driven and the roller 5 is a tension roller. The rollers 6, 7 are movable by a common driving mechanism (not shown) to compress the belt 1 against the roller 2 at the points D, G. Preferably, the roller 6 is made of stainless steel and is a heating roller. In operation, the rollers 6, 7 are moved away from the roller 2 in directions E 2 , H 2 . The roller 5 is moved in direction C 2  to tension the belt 1 to cause it to stretch and have its thickness reduced. The rollers 6, 7 are moved in directions E 1 , H 1  to press the belt 1 against the roller 2 and the roller 5 is moved in direction C 1  so that the portion 1b of the belt 1 contracts whilst the portion 1a thereof remains stretched and thinned. The sheet material 8 to be shrunk, e.g. knitted or woven fabric, newspaper or kraft paper, is wetted by a water spray 10 and is fed into the portion 1a. As the material 8 and the belt 1 pass the point D, the belt 1 contracts and its thickness is increased so that the material 8 in contact therewith is shrunk. Guide rollers 9 are provided. In another embodiment, Fig 2, the rollers 6, 7 are mounted on arms 11, 12 movable vertically by an oil pressure driving mechanism (not shown). Heating and calendering rollers 13, 14 having backing plates 15, 16 are disposed one on each side of the roller 6. In operation, the tension roller 5 maintains the belt portion 1a stretched during the rotation of the driving roller 2. In a further embodiment, Fig 3, two driving rollers 2a, 2b are provided, and are engaged through the belt 1, by the rollers 6, 7, respectively.

Abstract: 1300557 Automatic exchange systems MARCONI CO Ltd 6 April 1970 [14 April 1969] 19092/69 Heading H4K A time slot changing junctor for use in a TDM, PCM exchange comprises a plurality of stores equal in number to the number of channels in a frame on a highway of the exchange. The stores are disposed in a series chain between one subscriber's Go and Return highways. Gating arrangements are located between each store in the chain so as to shift a signal down the chain one step per time slot until the slot used by the other subscriber occurs whereupon the signal is gated out on to the second subscriber's Return highway whilst a signal on his Go highway is gated into the next store in the chain. The latter signal will of course reach the end of the chain i.e. the first subscriber's Return highway, during his alloted time slot. Particular description 10 Bit digital speech data from a calling subscriber A on input highway 1 is intermediately stored in the first one of 32 stores D1 to D32 prior to transmission towards the called subscriber B on output highway 1. The same store is used for transmission in the opposite direction i.e. from B to A, using highway 2. The stores D1 ... D32 are each separated from their neighbours by an AND gate 23 as is shown only for the link between stores D3 and D4. The inlet of each store except D1 is additionally connected to input highway 2 via a gate 24 while each store has an additional outlet connected via a gate 22 to output highway 1. In operation, signals from input highway 1 are shifted through the chain for a period equivalent to the delay between time slots A and B and are then read out to output highway 1 via a particular gate 22 and common gate 28. Simultaneously signals from input highway 2 are written-in to the next succeeding store via a particular gate 24 so that they appear on output 2 during A's time slot when the next speech sample from A is being inserted in D1. In the event that A and B use the same time slot, gates 26 and 24 (B (o))are utilized instead of the storage chain.

IPC: C11C3/00
Filed: 1928-07-05
Abstract: 295,275. Holzverkohlungs-Industrie Akt.-Ges. Aug. 8, 1927, [Convention date]. Esters of acetic, propionic, and other acids; methyl acetate. - Esterification of fatty acids with alcohols is effected under pressure at moderate temperatures such as those which correspond with saturation pressures of 2-8 atmospheres, in presence of limited quantities of catalysts which maintain the reaction mixture at pH = 1À5-3. the ester being continually removed for example by distillation. The reagents may be present in equivalent proportions or either may be in excess; they may be used in dilute or concentrated form. As catalysts, mineral acids, acid salts readily hydrolyzed salts may be used, such as sulphates of heavy metals. aluminium, magnesium and ammonium acid phosphates of alkalies and alkaline earths, borates, salts of complex acids and of organic sulpho acids may be employed, and salt mixtures giving a " buffer " action to maintain a constant hydrogen-ion concentration may be used. Some part of the esterification may be effected without catalysts, the catalysts being added after the esterification has progressed for some time. The operation may be continuous, and a high column or a set of three columns may be employed. In an example for the production of methyl acetate, acetic acid of 10 per cent strength is fed continuously into the. upper part of the middle, column which is heated so as to obtain 8-9 atmospheres pressure, and methanol is admitted at various points, in excess. Methyl acetate, methanol and water pass out to the uppermost column and are separated by fractionation. The effluent from the middle column, containing 3-4 per cent of acetic acid and some methanol, is discharged to the lowest column where it is preferred to add catalysts in suitable form, for instance 1 litre of 10 per cent sulphuric acid or of a 25 per cent solution of sodium bisulphate may be added for each 100 litres of the original dilute acetic acid, and a further quantity of methanol for the esterification of the remaining acid.

Title: Catalyst removal in the carbonylation reaction
IPC: C07C45/50
Filed: 1949-07-26
Abstract: Catalyst compounds are separated from reaction products obtained from the carboxylation stage of an oxo synthesis reaction in which carbon monoxide, hydrogen and olefinic hydrocarbons are reacted in the presence of a carboxylation catalyst, by injecting steam to decompose the catalyst compounds and to yield, on condensation, a dispersion of the catalyst metal in water which is separated from the reaction products and the catalyst metal is recovered.  Catalyst-free material may be hydrogenated to alcohols or oxidized to acids.  Many olefinic hydrocarbons are listed, representative being butylene, pentadiene, styrene, olefine polymers and fractions from hydrocarbon synthesis and cracking operations.  Catalysts are of the salt type, e.g. cobalt oleate or naphthenate and iron linoleate.  Conventional temperatures, pressures, feed rates and volumes of reactants are used in the synthesis.  The steam may be injected at 0-200 p.s.i.g., preferably about 90-125 p.s.i.g., and superheated to 212-400 DEG  F.  The catalyst metal is normally filtered from the aqueous dispersion and may be reused as catalyst in the synthesis after conversion to a suitable salt.  The recovered water may be used for steam production. In an illustration steam at 340 DEG  F. and 125 lbs. pressure is injected into a two-litre bomb containing carboxylation products from a C7 olefine, after draining water from the bomb over a period of half-an-hour a centrifuged sample of the cooled product contained 0.004 per cent cobalt as against 0.113 per cent before treatment. Specification 647,363 is referred to.
