Abstract: 1,143,324. Looms. J. L. CARD and W. E. PASSONS. 20 March, 1967 [19 March, 1966], No. 13051/67. Heading DIE. A fringe of cut or uncut loops 161, Fig. 10, of weft 39 is formed on a narrow strip of fabric having warp yarns 111, 112. The fabric is woven with the warp yarns horizontal in a vertical plane, alternate yarns passing through eyes 105, 106, Fig. 6, in rods 75, 76 respectively which are oppositely reciprocated by crank mechanism to shed the warp. The weft is inserted by a needle 33 which is reciprocated vertically in timed relation by a crank mechanism with the shredding mechanism, the fringe loop being retained by a looper 155 suitably actuated as the needle is withdrawn. A cutter is associated with the looper if a cut fringe is desired. Two or more strips may be woven on the same machine by providing additional warps co-operating with further sets of eyes on the rods 75, 76 and further weft needles. The crank mechanism for shedding may be replaced by hydraulic mechanism and a pneumatic hollow needle may be used for inserting the weft and blowing out a measured fringe loop. In this latter case the looper can be dispensed with.

Title: Hydraulic control installation for the bearing of a press cylinder shaft
IPC: B41F13/40
Filed: 1957-04-26
Abstract: 801,980. Printing-machines. SOC. ANON. DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES SAVIEM L. R. S. April 26, 1957 [April 27, 1956], No. 13364/57. Class 100(2) [Also in Group XXIX] T,ripping-arrangements. Hydraulic apparatus for loading the impression cylinder of a rotary intaglio printing machine comprises double-acting jacks 3, 4 having series-connected cylinders and supplied from a source of pressure 12 through a reversing valve 14. The jacks have piston rods 5, 6 connected to the impression cylinder bearings. The inter-connected chambers 7, 8 of the jack cylinders are permanently connected, through a line 11 and a restriction 13, to the pressure source 12. When valve 14 is moved to connect a line 16 or 15 to pressure to bring the impression cylinder to its working position or to retract it, the jack pistons are moved in unison, the restriction 13 preventing the passage of any significant quantity of liquid to or from the interconnected chambers during movement of the pistons. When, however, liquid supplied through line 16 to a chamber 9 has brought the impression cylinder into its operative position, the pressure in chambers 7, 8 becomes the same as that in chamber 9. The crosssection of the piston rods is half that of the pistons so that both pistons exert an. equal force on their associated bearings. In the modification of Fig. 2, the jacks have pistons 26, 27 in cylinders 20, 21 and piston rods 24, 25 in auxiliary cylinders 22, 23. The area of cross-section of the pistons is three times that of the piston rods. Liquid is supplied through a reversing valve 36 and line 44 to a chamber 28 to bring the impression cylinder to its worK- ing position and liquid expelled from a chamber 29 is supplied to the auxiliary cylinders 22, 23 and thus moves the piston rod 25 in unison with the piston rod 24. The inter-connected chambers 22, 23, 29 are connected through a restriction 43 to the source of pressure so that the pressure in these chambers is the same as that in chamber 28 when the impression cylinder is in contact with the printing cylinder.

Title: Naptha reforming and refining
IPC: C10G61/06
Filed: 1936-05-14
Abstract: <PICT:0475125/III/1> Naphtha is reformed, refined and stabilized by subjecting it to a reforming operation and subjecting the reformed products, without separation therefrom of low-boiling - products or substantial amounts of high-boiling-products, while still in the vapour phase, to catalytic refining at temperatures of 450 to 700 DEG F. in presence of an absorptive catalytic mass, the reformed products being cooled only sufficiently to bring them down to the refining temperature.  The catalyst used for the refining is an activated blend of silica and alumina.  The refined products are fractionated to separate the required anti-knock fuel, an intermediate fraction, and a heavy fraction, the intermediate fraction being recycled to the reforming stage.  Naphtha is fed by a pump 2 through heat-exchangers 4, 6, 8 and mixed if desired with steam supplied through pipe 11, is heated to 900--1120 DEG  F. in a coil 10 and then passed into a reaction chamber 13. Alternatively the naphtha may be heated to 850--950 DEG  F., only the chamber 13 then being supplied with catalysts comprising metallic oxides on porous carriers, e.g. china clay, pumice or activated aluminium hydrosilicate.  The treated vapours pass off through a line 14, heat-exchanger 8 and line 16 to a catalytic refining chamber 17 maintained at 470--700 DEG  F. and at the same or lower pressure prevailing in the chamber 13.  The vapours pass through or around the heat-exchanger 6 to a fractionating tower 21 from which the desired anti-knock fuel is taken off through a line 22, condensed in condensers 4, 24 and collected in a receiver 25. Heavy polymerized products are removed from the bottom of the tower 21 to storage or re-cycled through lines 32, 33, 35, to mix in line 5 with the incoming charge.  An intermediate fraction is removed through the line 36 and similarly treated.  In a modification, means are described for removing fixed gases from the reformed products before they pass to the refining stage. U.S.A. Specification 1,895,081 is referred to.

Abstract: 1349963 Slip-casting truck system J LIPPERT [trading as MASCHINEN-UND STAHLBAU JULIUS LIPPERT] 7 May 1971 [26 May 1970] 13776/71 Heading B5A [Also in Division B8] A casting truck for ceramic slip moulds comprises a base frame 2 on wheels movable along a track 4 and supporting a mould-carrying frame portion 12 in such a way that the latter can be tilted to either side of the track to discharge residual slip. A holder 15 for mould parts 13 and 14 is mounted on the base frame in such a way that it does not tip with the frame portion. The frame portion 12 carrying two moulds 1 is provided at each end with downwardly extending lugs 28 which have a hook-like portion forming a hinge connection by engagement with pins 26 so that the frame 12 can thereby be lifted clear of the base at one side and will pivot about the pin 26 at the other side. Pivotal lift to the left is obtained by a means of an off-centre, downwardly projecting bar 29 which is lifted when it passes over rollers 30, either the bar being bevelled or the rollers being inclined, so that the frame 12 is tilted into the position 12<SP>1</SP>. Pivoting to the right is effected by a hook arm 35 which engages a pin 36 and retracts to position 35<SP>11</SP> thus lifting the frame 12 into the position 12<SP>11</SP> where an extension 39 comes to rest against a set of rollers 37 in position 39<SP>11</SP>. This lifting operation and its reversal are arranged to operate automatically. The moulds are clamped in position by a pivoted clamping device 41 with a screw spindle 42 to clamp the mould closure member. The mould-part holder 15 comprises an upright 16 supported from the base 2 by being pivoted at 18 through supports 19 which carry stops 20, 21 to limit angular movement of the holder. Such movement is effected by a roller 45 carried on an arm 44 attached to the upright 16, the roller travelling in a track 43 which diverges to position 43<SP>1</SP> to tilt the holder. The carriage is guided along the casting track by a roller 7 depending from the base on a rod 6 and running in a channel 8 and is drawn along by engagement of the end of the cantilevered arm 10 in a chain 11. In a modified arrangement, Fig. 3, the arm 10 is replaced by a slide 47; a link 48 of the chain being inserted therein so that it will slide from one side to the other as the carriage moves around narrow curves of either hand.

Abstract: 586,451. Step-ladders. ALLAN, J. July 20, 1944, Nos. 13947 and 13948. Convention dates, Aug. 28, 1943, and Oct. 23, 1943. [Class 20 (ii)] The supporting prop of a step ladder or trestle,. pivotally connected to the front portion thereof, comprises a longitudinally disposed member or strut, a cross member pivoted intermediate its ends to this strut, a pair of prop legs one on each side of the strut and pivotally connected to said cross member, and link means spaced from said cross member and pivotally connecting the prop legs, said link means forming a guide for the strut during transverse movement thereof relative to the prop legs when the ladder is being set up on uneven ground. Alternatively the longitudinal strut may be pivoted to the link means intermediate the prop legs. The link means preferably comprise two links one on each side of the prop legs and pivoted thereto, forming a slot in which the strut works, the links also being capable of being arranged to extend adjustably between the prop legs and the strut for which purpose the strut is provided with a series of holes or a slot. The figures show the back prop arranged in three different ways. In Fig. 4 the front part 10 is on even ground and the prop legs 17 and cross member 16 have moved to take up an inequality. In this case the links 18 connect the prop legs directly and the longitudinal strut 13 is pivotally attached to the links by a bolt 21. In Fig. 5 the front portion is enabled to stand on uneven ground by removing the bolt 21 and allowing the strut 13 to swing in the slot formed by the links 18. The strut may be clamped in the adjusted position by suitable means, (not shown). In Fig. 6 one end of each link is disconnected from a leg and connected to the slot 22 in the strut by a common bolt 21, which can slide up and down the slot to enable the legs 17 to be moved towards and away from each other. Two possible positions are shown in full and dotted lines, the former enabling the prop legs to be placed in a constricted position, such as the corner of a room. The legs may be clamped in the desired position by wing nuts on the bolts 20, 21. Other arrangements of the legs may be obtained by extending one link from one prop leg to the slot 22 and the other from the other leg to the end of the strut 13.
