Abstract: 1,266,359. Telescopic masts. MODERN AERIALS Ltd. 29 Sept., 1970 [17 Oct., 1969], No. 51161/69. Headings E1B and E2B. [Also in Division F2] Inner and outer tubes of a telescopic mast are locked together, so that the mast can withstand axial loads, by rotating a sleeve 5 having an eccentric track 7 to exert a radial load on a roller 9 mounted in an aperture 11 in the outer tube and engaging beneath a lip 13 on the inner tube. When the sleeve is rotated to relieve the load the roller is urged outwardly by a leaf spring. In a second embodiment a block with an arcuate surface mounted on a continuous band replaces the roller and the sleeve has an open upper end closed by a disc and spring circlip to allow assembly. The mast has shock absorbing means in the base to prevent damage when the sections are dismounted.

Abstract: 1,266,382. Refractory bricks. DIDIERWERKE A.G. 2 June, 1969 [1 June, 1968], No. 27727/69. Heading F4B. A fired basic or neutral refractory brick 1 is provided with a layer of a refractory composition 5 and then with protective steel cladding or armouring 3. The refractory layer of up to 10 mm. thickness may be applied by adhesion to either the brick or the cladding or injected between them, in the plastic or the dry states. Preferably however an overthick preformed plastic layer of refractory material which will harden under applied pressure is applied to the brick face, and the cladding or armouring 3 is then pressed on to the layer by the rams 6 of a forming press, surplus composition material being squeezed out sideways for removal. Grooves 2 in the brick face help retain the layer in place, claws 4 on the cladding engaging in these grooves. Composite clad bricks formed of two or more brick materials may have a refractory composition layer, with a metal reinforcement embedded in it, interposed between the differing brick materials. The brick may be of the hanger type.

Abstract: 1289008 Anti-skid tyre attachments H WALDMANN 28 July 1970 [28 July 1969] 36575/70 Heading B7C In an anti-skid device which is fitted to a motor vehicle wheel and tyre, the tyre 1 has recesses 2 which extend obliquely to its tread band and in which slidable anti-slip bands 3 are disposed. The bands 3 have grip pads with studs 4 inserted in them and sliding displacement of the bands is effected by means of holding rings 7 to which the ends of the bands are fastened. The rings 7 are rotatable relative to rim 6 of wheel 1 so that, in one position of the band 3, the grip pads lie in the region of the tyre tread band while, in another position of the band, no grip pads lie in the region of the tread band. A pair of adjusting elements in the form of bowshaped members 12, 13 or 43, 44 is mounted on the holding rings 7 and a control element, such as a control roller 18 and control cylinders 19, 20, may be moved into the path of movement of the adjusting elements. The cylinders 19, 20 may be operated hydraulically, pneumatically or mechanically and the control element is connectable to the vehicle. An adjusting device for the holding rings 7 is in the form of a pawl 24 loaded by a spring 23, the tip 25 of the pawl engaging a toothed segment 26, and the adjusting device being adapted to be operated step by step, at least once for each rotation of the wheel, by each deflection of the adjusting element produced by the control element. In the embodiment of Fig. 4, each bow-shaped member 12 or 13 is connected to the rim 6 through a pre-stressed spring 15 or 16 respectively. If the control roller 18 is moved from the position shown in solid lines to that shown in broken lines, i.e. in the direction of arrow 21, on each revolution of the wheel it will contact once the apex region of the bow 13 and rock this into the position 13<SP>1</SP> causing the pawl tip 25 to move one tooth along the segment 26 while the oppositely situated pawl 24<SP>1</SP> mounted on the bow 12 is at the same time lifted out of the toothed segment 26<SP>1</SP> by means of the bow 13. When the control cylinder 20 moves out in the direction of the arrow 22, on operation of the control cylinder 19, the control roller 18 engages the bow 12 and operates the bow once for each revolution thus advancing the pawl 24<SP>1</SP> one tooth along the segment 26<SP>1</SP>. In a further embodiment, the control device works hydraulically. Two double acting power cylinders 30, 31, Fig. 5, are fastened on one of the holding rings 7 whose opposite sides are joined by a moment balancing rod 32. One side of the power cylinders 30, 31 is in each case connected, by pipes 33, 34 respectively, to a pump 35 fastened on the rim 6 while the opposite sides of the power cylinders are connected by pipes 36 and 37 respectively to a second pump 38 on the rim 6. The power cylinders 30, 31 adjust the control roller 18 so as to operate bow members 43, 44 respectively. Fig. 7, so as to displace the anti-slip bands 3 in one direction or the other.

The paint does not blister, flake or peel from the moulded article. Alternatively, the article may be "pre-painted" by coating the barrier layer with a layer of a reactive paint such as an epoxy coating composition, the resultant moulding, after washing, having a painted surface. Examples given of barrier layers are:- partially hydrolysed polyvinyl acetate, polyoxyalkylene glycols, polyvinyl pyrrolidone polymers, polyvinyl methyl ether/maleic anhydride copolymers, hydroxy substituted acrylate polymers, gelatin, albumin, starch, sugars, α-methyl glucoside and sodium silicate. A surfactant may be added to the barrier layer solution to effect faster wetting of the mould release film. The polyurethane moulding composition may include a blowing agent.

Abstract: 1324434 Finishing fabrics D PERNICK 5 Oct 1970 47282/70 Heading D1S Apparatus for spreading a length of loosely draped fabric F comprises two sets of oppositely disposed tenterhooks 20 for impaling thereon opposed portions of the fabric F and control means for rotating the angular orientation of each set of tenterhooks as they are caused to diverge so that each portion remains impaled on the tenter-hooks of a set as the divergence of the two sets spreads the fabric into substantially flat-form. As shown, tenter pins 20 are supported on plates 21 mounted on carriers 28 each pivoted by a pin 30 between two spaced arms 27 on a bracket 24 comprising a link of a tenter chain 13, 14. Coil springs 31 bias the carriers 28 to pivot downwardly to the position of Fig. 5, this downward movement being limited by the cooperation of surfaces 32, 33 on the arms 27 and the carrier 28. The carriers 28 are locked in the position of Fig. 6 by the cooperation of feet 35 on levers 29 pivoted to the arms 27 with notches 34 on the carriers 28. Springs 36 urge the levers 29 downwardly. Upon upward rotation of the carriers 28, the feet 35 are engaged by surfaces 37 on the carriers 28 to cam the levers 29 in the upward direction. The carriers 28 are moved from the orientation of Fig. 5 to that of Fig. 6 by the engagement of arms 40 thereon with a cam plate 38 shaped as shown in Fig. 3. The spacing between the chains 13, 14 is adjustable by a handwheel 54 arranged for simultaneous operation of threaded shafts 52, 53.  A tubular knited fabric F, Fig. 5, is draped loosely over spaced V-belts 16, Fig. 1, and is fed thereby onto guide bars 17, 18, Fig. 5. A cutting knife 12 driven at high speed slits the fabric longitudinally. Immediately in advance of the bars 17, 18 the fabric is engaged by opposed tenter pins 20 on chains 13, 14. Preferably, the conveyors 16 are driven at a slightly higher speed than the chains 13, 14 to overfeed the fabric. As the chains advance, the carriers 28 are gradually pivoted through 90‹ to the position of Fig. 6 by the plate 38 and are locked by the levers 29. The chains 14, 15 diverger until the fabric is held in open width form and then continue parallel along sections 13a, 14a in which the fabric is steamed by a box 41 and cooled by an air nozzle 42. As the carriers 28 approach the discharge end of the chains 13, 14, the levers 29 are displaced by cams 47 engaging arms 46 so that the carriers 28 pivot back to their original positions. The fabric is de-pinned and passes over guide rollers to be wound into a roll at a station 15.
