Title: Improvements in looms for weaving royal axminster or moquette carpets and other tufted pile fabrics
IPC: D03D39/02
Filed: 1931-10-24
Abstract: 382,064. Weft-inserting and beating- up mechanism for pile fabric looms. PLATT BROS. & CO., Ltd., Hartford Works, Oldham, and BASSINDALE, I. B., Cleveland, Oldham Road, Grasscroft, Yorkshire. Oct. 24, 1931, No. 29528. [Classes 142 (ii) and 142 (iii).] In looms wherein the pile tufts are formed around the wefts, the weftinserting needles are guided between the dents or teeth and one or more fingers or plates provided on a reed or lay which can be raised to bring the fingers into guiding position and lowered to move the fingers clear of the weft threads being beaten up and clear of the comb for turning up the pile tufts. The additional guides may be provided on a reed or lay adapted to beat-up one or more weft threads whilst leaving other wefts to be beaten up by another reed or, on a reed serving to beat up wefts left untouched by another reed. Alternatively, the guides may be provided on a reed adapted to beat-up different weft threads successively. In the construction shown, a lay a, Figs. 1 and 2, slidably mounted on a second lay d and provided with an open-ended reed a<1>, is provided with fingers b which are so positioned that two superposed needles m, n can pass between the fingers and the reed a<1>, each finger being mounted in line with a tooth of the reed and adapted to pass between the warp threads. The lay a is operated through rods f and levers g from cams which are so formed that the reed a<1> and guides b are moved from the highest or guiding position, shown on Fig. 2, through two intermediate stages, which permit of the wefts being moved nearer the fell of the fabric and the tufts inserted, to the lowest or inactive position in which they are clear of the fabric and the reed e may beat up all the wefts. The cams j are mounted on a shaft k which is driven at the same speed as the tappet shaft l, the latter carrying an operating cam p for the main lay d.

Title: Improvements relating to the isomerisation of paraffin hydrocarbons
Inventor: GOBLE ANTHONY GEORGE
IPC: B01J27/13
Filed: 1960-09-07
Abstract: The isomerization of C4+ paraffins in the gasoline boiling range to obtain more highly branched products is effected in the presence of hydrogen at below 400 DEG  F. with a catalyst prepared by contacting a hydrogen-containing alumina with a compound of the formula <FORM:0953189/C3/1> in which X and Y may each be H, Cl, Br, F, or SCl or together are O or S, under non-reducing conditions and at a temperature such that chlorine is taken up without the formation of free aluminium chloride (see Specification 953,187 [Divisions B1 and C1]).  The catalyst may also contain 0.01-5% wt. of a hydrogenating metal, e.g. platinum or palladium and minor amounts of other refractory oxides, e.g. silica, titania, beryllia, zirconia or magnesia. The alumina should have a surface area above 250 m.2/g. and be treated to a chlorine content of 1-15% wt. or 2 x 10-4 to 3.5 x 10-4 g./m.2 o surface area. The hydrocarbon feedstock should be free from sulphur, water and aromatics and low in naphthenic content. Isomerization is effected at 50-400 DEG  F., 0-2000 p.s.i.g., 0.05-10 vol./vol./hr. and 0.01-20 mols. hydrogen per mol. hydrocarbon.  When converting normal paraffins, unconverted feed may be separated from the product, e.g. by molecular sieves, and recycled.  Specifications 897,238, 899,378 and 926,995 also are referred to.

The machine comprises a platform 22 with dependent flanges forming a housing, the side-flanges having upstanding side-plates 38, 39 and the front-flange being cut away to accommodate a toothed guard 32. At the rear of the machine, a height-adjusting roller 25 is mounted. A bifurcated handle 28 is integral with a pair of plates 48 pivoted to the side-plates 38, 39 the plates 48 carrying the stub-axles of the ground-wheels 23, 24 and the arrangement being that elevation of the handles interrupts the drive by disengaging the ground-wheels from the driving rollers 70, 71, the handles moving over-centre so as to be self-sustaining in either position. To allow for various working-heights the pivots 51 on the handles 48 are movable into various holes 53 in the side-plates 39. The motor 27 drives the cutter-blade spindle 27a directly and is connected by a belt 86 to a pulley 87 on a stub-shaft 88b in a gear-box 22 f through which the shaft 65 passes. A face-gear 93 is integral with the pulley and has two concentric rings of gear-teeth 93a, 93b with which a pinion 95 on the shaft 65 is selectively engageable : the pinion is keyed to the shaft and slidable along it. The gear-box 22f may contain oil, which is prevented from escaping by a flange 87a on the pulley 87. The tension of the belt 86 is adjustable by a jockey-pulley 106, the pulleys 87 and 106 being enclosed between the platform 22 and a cover-plate 116 over the cutterblades 75. The rear part of the platformcasing 22 is formed with an opening 29 for the ejection of cuttings. For cutting-up leaves, a casing 130, Fig. 12, is mounted below the platform 22, the blades 75 being fitted with detachable upstanding lugs 127. The rear part of the casing 130 is perforated to allow the passage of pulverised leaves. Specification 777,642 is referred to.

As shown in Fig. 2, a web passes over a guide roller beneath a tensioning roller 2 and over a guide roller 3. The roller 2 is supported by a transverse support 12 secured to flanges 11 each adjustable vertically of a bracket 6 by means of a slot 9 and clamping screw 13. The bracket 6 is horizontally adiustable along a frame 5 by a slot 7 and clamping screw 8. The bushes 18a, 18b, Fig. 8, have multi-start left and right hand screw threads respectvely, the pitches of which increase towards the roller ends. In a modification, Fig. 7, (not shown), the bushes may occupy nearly the entire length of the supporting shaft, the threads thereon being multistart and the number of starts increasing towards one end. The tops of the threads are preferably flattened as in Fig. 15 (not shown). In a further embodiment, Fig. 13 (not shown), threaded bushes are provided at the extreme ends of the roller, the remaining bushes being curved or tapered so as to form a tapered roller. In a further embodiment, Fig. 16 (not shown), a shaft carrying the tubular bushes is mounted on arms for vertical adjustment to permit variation in the tension on a web being stretched.

Abstract: 1415028 Practising apparatus A C ANGELOS 26 June 1973 [13 March 1973] 30261/73 Heading A6D Apparatus for detecting the amount of spin imparted to a ball (e.g. the amount of 'slice' or 'hook' of a golf ball) when hit from a point of origin 6, comprises an impact surface 9 positioned in the path of travel of the ball, detector means 10 positioned between the point 6 and the surface 9 for detecting a first point at which the ball passes the detector means as it is travelling towards surface 9 and for detecting the location of a second point at which the ball rebounding from surface 9 again passes the detector means, and means for comparing said first and second points to determine the amount of spin imparted to the ball. In the embodiment shown the detecting means 10 comprises a series of photo-detectors illuminated by light sources 12 each detector being associated with a switch and a resistance in an electric circuit (Fig. 3, not shown) arranged so that the voltage across the circuit corresponds to the detector or detectors operated by the ball. The circuit also includes a capacitor for storing the voltage corresponding to the detector actuated as the ball travels to the impact surface and another capacitor for storing the voltage corresponding to the detector actuated by the rebounding ball. These voltages are compared so as to produce and output indicative of the amount of spin imparted to the ball. If there is no spin on the ball i.e. the angle of reflection of the ball from the impact surface is the same as the angle of incidence then the voltages are the same and no output signal is given. If there is spin imparted to the ball then the angle of reflection is different from the angle of incidence thus producing different voltages across the circuit the difference in the voltages being indicative of the degree of spin and also its direction i.e. whether it has been hit with a 'slice' or 'hook' effect.
