Abstract: 1,250,410. Rolling mills; making continuous strip. NIPPON KOKAN K.K. 22 Dec., 1969 [8 Jan., 1969], No. 62411/69. Headings B3A and B3M. A continuous steel-strip rolling mill incorporates apparatus for welding together the ends of strips to form a long continuous strip, a horizontal looper positioned above overhead cranes 17 and 18 for storing a length of strip to enable such welding to take place without interrupting the rolling programme, and several roll stands in tandem for cold rolling the strip. In operation, strip is unwound from a coil 8 whence it passes around rollers 16, 14 and 15 to the looper. The looper includes fixed rollers 23-25 and rollers 19 and 20 which are biased by a winch 35 towards the left. The strip leaves the looper and passes to the stands 30 of the mill. Before the coil 8 is completely unwound, a new coil 6 is located nearby and its leading end uncoiled. The trailing and leading ends of the respective coils are sheared, butt-welded together at a station 13, and the weld cleaned. The looper accommodates the halt in the strip supply during welding without affecting the operation of the stands 30. After the welding, the coil 6 is moved into the position of coil 8 and a new coil 1  is positioned ready for a similar joining operation.

[Also in Divisions G4-G6 and H2] In an arrangement for detecting an impedance variation, due to a short-circuit or open-circuit, on a transmission line terminated by its characteristic impedance, the line is connected to terminals 14 so as to form at least part of one arm 12 of an impedance bridge 9 ... 12 and an imbalance detector having two sets of contacts is connected across a bridge diagonal, the operation of the detector causing a respective one or other of the two sets of contacts to change its state to operate a " trigger " relay R1 to cause the giving of an alarm or the operation of a safety device. The two sets of contacts may be the contacts of a polarized relay having a central off position, Fig. 1 (not shown), but as shown, may be the contacts of relays R 2 <SP>1</SP> and R 2 <SP>2</SP> having their operating coils connected in series with thyristors TH1, TH2 to an A.C. supply 2. The control electrodes of the thyristors are connected to resistors 25, 26 which are in series with transistors T1, T2 having their bases connected across the bridge diagonal, a D.C. supply 3, 5 being connected across the other bridge diagonal. Normally the bridge is balanced, the transistors T1, T2 are non-conductive and the thyristors TH1, TH2 conduct. The relays R 2 <SP>1</SP>, R 2 <SP>2</SP> are energized with their contacts closed so that the relay R1 is energized. On imbalance, one or other transistor conducts to render the associated thyristor non-conductive, so that one or the other relay R 2  releases to de-energize the relay R 1  which releases to complete alarm and control circuits 16, 17. The transmission line may be a telephone line which may be short-circuited or open-circuited under fault conditions, or by the operation of a switch or temperature responsive device.

Abstract: 1,252,469. Water gas shift reaction. ESSO RESEARCH & ENG. CO. 24 March, 1969 [8 April, 1968], No. 15234/69. Heading C1A. Hydrogen is prepared by passing a gaseous mixture comprising carbon monoxide, steam and a small amount of sulphur impurities over a catalyst comprising an alkali metal salt derived from an acid having an ionization constant of less than 1 x 10<SP>-3</SP>, the carbon dioxide concentration in the gas mixture being maintained at at least 5 mol per cent. The CO 2  concentration is maintained at at least 5% by recycling CO 2 , by the addition of extraneous CO 2 , or by carrying the reaction out in two stages, the first at 700- 900 F. to effect partial conversion of CO to CO 2  and the second at 500-650 F. to complete the reaction. In this embodiment, the feed is partially converted to CO 2  in a high temperature stage using a suitable catalyst such as Fe 2 O 3  promoted with Cr 2 O 3 . When the partial conversion in this first stage results in the CO 2  concentration which is required for the second stage, this mixture is fed into a low temperature reactor preferably at 400-700 F. and passed over a catalyst consisting of an alkali metal salt. Salts specified are the carbonate, biphosphate, aluminate, hydroxide, acetate etc. of sodium, potassium, lithium, rubidium and caesium. Caesium and potassium carbonates are particularly preferred.

Abstract: 1290760 Composite yarns; false twist method KANEGAFUCHI BOSEKI KK 16 Nov 1970 [15 Nov 1969 7 April 1970] 54341/70 Headings D1F and D1W A method for the production of synthetic fibres comprises false twisting a fibre having an at least partially layer multiplied structure composed of at least two polymers having a poor mutual affinity so as to at least partly separate the components of the layer multiplied structure. By the term 'layer multiplied structure' is meant a structure wherein at least two polymers are mixed or adhered forming a large number (at least 4 preferably at least 8) of layers in a fibre or unitary filament and in which the main layers of polymers extend substantially (i.e. for at least several centimetres) along the length of the fibre. The layer multiplied structure may be 'grainy', i.e. a number of layers of at least two polymers having substantially the same thickness; 'archipelogic', i.e. similar to an arrangement of islands in an ocean; or 'nebular', i.e. similar to the arrangement of stars in a nebula. Examples of polymer combinations having a poor mutual affinity are polyamide/polyester and polyamide/polyolefins. The layer multiplied structure may be composed of at least 5 layers, preferably at least 8 layers. The false twist process may be carried out continuously by means of a rotating spindle, friction means or an air jet and may optionally be accompanied by heat setting using a plate or tube heater. Alternatively the false twist process may be carried out discontinuously using separate steps of twisting and untwisting, the initial twist being preferably inserted using a ring twister, double twister or uptwister. The process may optionally be accompanied by heating which may comprise heating the fibre on a bobbin using steam or hot water. The false twist process may be carried out under conditions which produce a crimp in the yarn. The degree of separation (or fibrillation) of the polymers in the layer multiplied structure determines the look and feel of the yarn. In a preferred embodiment, one of the polymers is a hydrophobic polymer and the other polymer is a hydrophilic polymer and the fibre is treated with at least 2% by weight of water, based on the weight of the fibre, after spinning thereof. By hydrophobic is meant having a water absorption less than 5% by weight and by hydrophilic is meant having a water absorption greater than 5% by weight. On treatment with water, the water content of the hydropbilie polymer is at least 1% greater by weight than that of the hydrophobic polymer. The water is preferably applied in the form of a spinning oil composition containing at least 20% by weight of water. The layer multiplied structure fibre is produced using a spinneret comprising a number of superimposed distribution plates such that the two polymers are placed in reservoirs and are initially joined at channels to form sideby-side polymers. The side-by-side polymers are repeatedly divided and joined by the distribution plates and extruded through orifices in the conventional manner.
