Title: Improvements in or relating to apparatus for controlling the feeding or supply of flexible strip material
IPC: B21D43/02
Filed: 1946-05-07
Abstract: 613.471. Feeding webs. FORD MOTOR CO. Ltd., and LEEK, J. W. May 7, 1946, No. 13817. [Class 100(i)] [Also in Group XXII] Apparatus for feeding, without backtension, metal strips, rope, paper &c. to a machine, comprises rollers 5, 6, both of which may be driven, which draw the strip 2 from a supply roll 3, through a switch 8 set to stop the apparatus in the event of strip breakage, into a box 1 of approximate strip width and considerable depth. The entry feed to the box 1 is greater than the exit feed to the machine so that slack accumulating to a predetermined amount on a resilient apron 12 depresses it, operating a switch 16 controlling the motor 8 driving the entry rolls 5, 6. As the machine continues operation the accumulation decreases and the apron 12 rises, restarting the entry feed. In a modification the apron 12 is rigid, end-pivoted, and counterweighted, and controls hydraulic, electric &c. means to stop and start the entry feed by raising or lowering one of the entry rollers 5 used as an idle pressure roller. Specification 613,472, [Group XXII], is referred to.

Title: Improvements in and relating to magnetic separators
IPC: B03C1/04
Filed: 1945-06-02
Abstract: 610,322. Magnetic separators. PHILIPS LAMPS, Ltd., TAYLOR, H. G., and GREGSON, R. F. June 2, 1945, No. 13909. [Class 72] In an arrangement for removing magnetic material from liquids, a non-magnetic tray or chute 1 normally inclined with its base immediately above a magnet or magnets 4, is capable of being displaced relatively to the magnet or magnets whereby magnetic material is no longer attracted to the chute and can be washed off by the liquid in the chute and discharged into a receiver 18 separate from that (the bucket 8) receiving the magnetically cleaned liquid. The said bucket 8 is adapted to tilt and discharge when filled to a predetermined level, and is coupled with and .operates the chute-displacing means. In Figs. 1 and 2, liquid enters the chute 1 from a supply 3, the magnetically cleaned portion entering the bucket 8 via a pipe 14. On tilting, the bucket rotates on its axis and by means of lever arm 12 and chain 13 pulls down the inlet end of the chute, raising the delivery end out of contact with the magnets 4. Material retained on the chute is thus washed by the liquid remaining thereon into a container 18, where it may be mechanically filtered and returned to the sump 17 for re-use. A filter 1<1> and weir 19 may be fitted to the chute, in order to retain non-magnetic particles and to ensure a sufficiency of liquid washing back respectively. In a modification, Figs. 3-5 (not shown), two chutes side by side are provided, and two buckets rigidly connected to each other and arranged both to tilt alternate chutes into and out of operative position and to move the liquid supply to be over the operative chute, are provided. Magnetic or float-controlled retaining devices may be associated with the bucket or buckets to ensure tilting does not occur before the bucket is sufficiently filled, whilst their base or bases may be provided with an adjustable drain 15 to vary the rate of filling and hence the frequency of tilting of the chute or chutes.

Title: A method of manufacturing pyridine derivatives
IPC: C07D213/48
Filed: 1960-04-21
Abstract: Aldehydes of the general formula: <FORM:0948004/C2/1> in which R1 and R2 are hydrogen atoms or alkyl, aralkyl or aryl hydrocarbon groups are manufactured by condensing an unsaturated aldehyde of the general formula R1CH2 CR2=CHCHO with a secondary amine R3R4NH, in which R3 and R4 are alkyl or aryl hydrocarbon groups or are joined together forming a heterocyclic ring with the nitrogen atom, in water or in an organic solvent at a temperature between -30 DEG  and +50 DEG C.; treating the resulting product of formula <FORM:0948004/C2/2> at a temperature between -30 DEG  and +50 DEG C. with a formylating agent of general formula R3R4N. CHCl2, obtained by the reaction of carbonyl chloride with a disubstituted formamide R3R4NCHO, in the presence or absence of an organic solvent which may be excess disubstituted formamide; and cyclising the intermediate of formula <FORM:0948004/C2/3> by treatment with aqueous ammonia or an ammonium salt solution at a temperature between 15 DEG  and 95 DEG C. Alternatively the formylating agent may be obtained by reaction of POCl3 and the disubstituted formamide. In a modification the first intermediate of formula <FORM:0948004/C2/4> may be converted into the amino diene of formula R1CH=CR2.CH=CHNR3R4 by distilling under reduced pressure before reacting it with the formylating agent. In an example crotonic aldehyde is treated with dimethylamine to give 1, 3-bis-dimethylaminobut-1-ene which is added to a reagent prepared from dimethylformamide and phosgene; and the intermediate of formula <FORM:0948004/C2/5> so formed is then heated with ammonium chloride to give nicotinic aldehyde.

Title: Manufacture of can bodies
IPC: B21D51/26
Filed: 1971-05-11
Abstract: 1356462 Making cans; bending; seaming METAL BOX CO Ltd 25 April 1972 [11 May 1971] 14152/71 Headings B3A B3E and B3J An end neck and an end flange merging therewith are formed simultaneously on a can body while rigidly supported internally by relative rolling motion between the body and an external necking tool. A can end is subsequently seamed onto the flange, while reforming of the neck takes place. In Fig. 5, the can body 20 is shown gripped by an expandable mandrel 21 shown contracted in section in Fig. 4. First jaws 22<SP>1</SP> are movable radially outwardly against springs 45 by axial movement of a chamfered sleeve 40. Smaller second jaws 49 are simultaneously moved radially outwardly against springs 50 to fill in the circumferential gaps between jaws 22<SP>1</SP>. The expanded jaws together with a non-expandable part 28 of the mandrel offer surfaces on which the neck 23 and flange 24 are formed by necking rollers 26. Preferably two diametrically opposite rollers are used, moved radially inwardly together but at different distances from the mandrel axis 25. The mandrel may be driven, or the rollers 26 may be driven and circle about the mandrel, or the necking tool may be a fixed bar of suitable profile. The diameter of the flange may be greater than, equal to, or less than that of the body, and in the first case the non-expandable part of the mandrel may be movable of smaller diameter than the neck and be movable transversely of its axis towards the necking tool, Fig. 7 (not shown). In another form, the mandrel jaws 86, Fig. 14, are mounted on a member which includes an annular ring 92 radially outside the can body offering a surface 105 on which the can body initially abuts. Neck and flange formation by tool 26 is constrained by a surface 96 on ring 92 which intersects the path 107 which would be taken by the flange end in the absence of such constraint. Fig. 16 shows a first seaming operation, in which a can end member 80 with seaming flange 110 is partly seamed on by a seam forming profile 123 of a first seaming roll 108, while a further profile 111 on the roll simultaneously reshapes the neck profile from 23 to 23<SP>1</SP>. Similarly in a final seaming operation a second seaming roll completes the seam while simultaneously reshaping the neck profile still further. The can body may be open at one or both ends, necking, flanging, and seaming taking place at the or both ends.
