Abstract: 1,139,416. Microwave coupling devices. MARCONI CO. Ltd. 8 Feb., 1966 [29 March, 1965], No. 13232/65. Heading H1W. The isolation ratio between two ports which are nominally isolated, for one direction of propagation, in a multiport system having non-reciprocal or quasinon-reciprocal properties, is improved by feeding signals in antiphase through an additional path between the two ports. The arrangement may be applied to a three-port circulator having ports 1, 2, 3 in which isolation is required between ports 1 and 3 when transmission is in the direction 1#2. An additional (decoupling) path is connected between ports 1 and 3, the path being so dimensioned, or so provided with variable phaseshifters and attenuators, that the signal transmitted therethrough is equal in amplitude and in phase opposition to the leakage signal, whereby the latter is cancelled. The decoupling path may be connected at either end to the ports of the circulator by slot couplers of about 12 to 15 db. The invention may also be applied to duplexers using hybrid junctions or hybrid ring couplers.

Abstract: 1477810 Cementitious compositions AALBORG PORTLAND-CEMENT-FABRIK A S 1 April 1975 [2 April 1974] 13233/75 Heading ClH [Also in Division B5] Particulate sulphur is mixed into wet clay, plaster or cementitious compositions used for moulding porous articles, and after moulding an article it is dried at below the melting point of sulphur before heating to above the melting point to cause the sulphur to flow into the small cracks and pores to strengthen the material after it solidifies on cooling. The regular voids resulting from this flow of sulphur are said not to affect the strength. Cement, pebbles, gravel, water, spherical sulphur particles of grain size 0.5 to 2 mm, and optionally a fire retardant for the sulphur are mixed and cast. After setting the article is gradually dried by heating to 100 C or to 60 C and then 90 C for a longer period, and are then heated to 119-155 C to melt the sulphur. The sulphur need not be melted in the middle of the article so that only the outer region is strengthened and protected against wear, water penetration and acid attack. Building blocks or in situ structures or roads may be cast. Wall and ceiling panels may be similarly moulded from gypsum mixed with water and sulphur spheres; and pipes, vases and building blocks from moist clay mixed with sulphur spheres.

Abstract: 443,752. Making metal wool. STEVENS, A. H.. 5, Quality Court, Chancery Lane, London.-(Rhodes & Co., J. H.; 153, West Austin Avenue, Chicago, U.S.A.) May 3, 1935, No. 13286. [Class 83 (iii)] A machine for making metal wool from wire comprises two grooved drums 10, 11, around which the wire 20 passes in a number of elongated loops past vertical banks of cutters, the grooves of the driven drum 11 being of V-shaped cross-section, Fig. 6, to afford traction for the wire strands. The drum 11 is driven from a motor 16 through bevel gearing 18. The wire is fed to the lowest groove of the drums through a straightening device 21 which applies drag and after passing round the drums in a series of loops is directed by idlers 23, 24 to a tensioning device 22. The horizontal runs of wire move past a bed 25 fitted with vertical blocks 26 each associated with knives 27 mounted in holders 29 pivoted to brackets 31 and adjusted by set-screws 32, 33. The knives of each vertical tier engage alternate strands and the knives of the next tier with the intervening strands. The blocks 26 are hollow and are supplied with cooling water by pipes 35. The fronts of the blocks are grooved to direct the wire over detachable inset wear strips 37 which resist the pressure of the cut. Vertical tensioning rolls 41, 42, one on each side of the wires are arranged at each end of the machine, the outer rolls 41 being movable rearwardly by screws 46 to increase the tension if required. At the rear of the machine, a take-up device equalizes the tension or all the strands. This consists of two vertical tiers of adjustably spring-pressed wheels 48 mounted on pivoted arms 49, the wheels of each tier engaging alternate strands. The roller 53 of the tensioning device 22 is mounted on a driven shaft 55 and is geared at 56 to the coacting roller 54 which is grooved to guide the wire.
