IPC: B21D39/20
Filed: 1958-11-04
Abstract: 866,994. Tube expanders. RAST, W. Nov. 4, 1958 [Nov. 13, 1957], No. 35420/58. Class 83(4). An expander for tube ends comprises a plurality of jaws 5 adapted to be inserted in a tube and moved radially apart to expand the tube end by axial movement of a tapered drift 6. The jaws 5 are held from axial movement by a threaded holding member 4 screwed on a body part 1 and having an inwardly-directed flange 9 to confine flanges 12 on the jaws 5, pins 11 on the jaws being guided in slots 10 in the flange 9. A circlip 15 urges the jaws 5 towards their contracted position. The drift 3 is moved axially by a cam 17 on a handle 16 pivoted at 18 to the body 1, itself provided with a handle 20. Spring return means may be provided for the handle 16 or drift 3. In a modification, Fig. 6, each jaw is formed with a recess 21, used for first de-burring the end of the tube by forcing the burred metal outwards, and a ridge 22 to form a ridge in the tube.

Abstract: 1,048,476. Dispensing articles. K. GÍTZE, [trading as NORD-WEST-PAPIERWERKE KARL GÍTZE]. Sept. 9, 1963 [May 11, 1963], No. 35488/63. Heading A4T. [Also in Division G4] Apparatus for dispensing carrier bags comprises a rotatable ejector 14 having an inclined portion 18 which engages behind the first of a series of carrier bags 13 fed by a slide 11 and takes the bag from the slide so that it can be removed from the apparatus. As shown, the handle loops 12 of the bags 13 are suspended from the slide rail 11 and are normally retained thereon by an ejector disc 14. The ejector disc has a radial slot and a portion 18 bent out of the plane of the disc in such a manner that on rotation, it engages behind the handle or handles of the first bag and displaces it off the slide rail 11 into a tray 19. Dispensing may be initiated by a switch or insertion of a coin into a mechanism 22 which, through a relay 21 and limit switch 23, cause a motor 19 to rotate the ejector disc 14 through one revolution. A hinge 26 allows the ejector system to pivot outwardly to permit access to the slide rail.

[Class 39 (i).] Barium 3 or other highly oxidisable metal for activating a cathode is carried on the anode 1 in a pocket 2 shaped so that the metal is protected against oxidation, and, when evaporated, is directed as a strip of vapour through a gap 4. The pocket may be formed around the metal or it may be formed in the anode, the ends being squeezed after insertion of the metal. The anode is heated slowly to the temperature at which gas is driven off both from the anode and from the metal, and the metal is then evaporated. The Specification as open to inspection under Sect. 91 comprises also the use of alloys fusing at a high temperature such as tin-barium, aluminium-barium, aluminium-calcium, for producing the vapour. This subject-matter does not appear in the Specification as accepted.

Classes 120(2) and 120(3) In the manufacture of a fancy, slubbed and cored yarn, at least one bundle of filaments is fed to a turbulent fluid zone at a constant speed and simultaneously therewith at least one bundle of "slubbing" filaments is fed to the same zone (a) at the constant speed and (b) at a speed at least 50% higher than the constant speed, the speed being interchanged intermittently, randomly, and rapidly between the two speeds (a) and (b) to produce a randomly occurring series of overfed filaments to be fed into the zone and thus form intermittent slubs with the constant speed filaments serving as a core thread, and the final yarn is collected at a speed less than the constant speed and without insertion of twist. The bundles may comprise viscose rayon, cellulose acetate or triacetate, nylon, polyethylene terephthalate or acrylic continuous filaments or yarns spun from staple thereof or natural fibres such as wool and cotton and may be of different colours and/or denier and/or lustre and/or comprise filaments of varying denier and/or colour. As shown in Fig. 1, bundles 1 and 2 of core and slubbing filaments drawn from packages 3 and 6 are passed, at constant speed by rollers 4 and at varying speed through the nip between conical roller 8 and cylindrical roller 9, to an air jet 5 and the composite yarn 12 formed therein is collected at constant speed on a cheese 13. A rail 11 is rapidly displaced and restored at random intervals by mechanical, electronic and/or pneumatic apparatus (not shown) to cause guide 7 to shift the bundle 2 between nipping positions on the conical roller corresponding to the speeds (a) and (b). In a modified apparatus, Figs. 2 and 3 (not shown) a stepped roller comprises two portions co-operating with separate cylindrical rollers to form nips corresponding to speeds (a) and (b) and between which the bundle 2 is moved by a rail as at 11.

Abstract: 905,453. Damping apparatus for printing- machines. MILLER PRINTING MACHINERY CO. Oct. 18, 1960 [July 12, 1960], No. 35644/60. Class 100 (2). Apparatus for dampening the plate 6 on a cylinder 5 in a lithographic offset printing press comprises a roller 4 in a fountain 2 containing water 3, a form roller 7 and a distributer roller 8 both rotating synchronously with the cylinder 5, and a metering roller 9 rotated by surface contact with the rollers 4 and 8. Roller 4 is driven independently at a slower speed than the roller 8 and since the roller 8 is at a lower elevation than roller 4, the roller 9 bears more on roller 8 and tends to be rotated at its speed. A reduction in the speed of the roller 4 decreases the quantity of water applied to the plate 6 and vice-versa. Roller 9 may be of metal with a knitted cotton sleeve 10. Roller 8 vibrates endwise relative to the rollers 7 and 9.

Abstract: 969,001. Locating conductive and magnetic bodies. INTERNATIONAL INSTRUMENTS Inc. Oct. 19, 1960, No. 35885/60. Heading G1N. In an induction sensing arrangement responsive to the change of coupling between coils, an amplifier connected to the pick-up coil produces maximum output when the induced electrical energy is decreased. In an indicating meter an aluminium vane 45 carried by pointer 27 is arranged to change the coupling between coils L1, L3, L2, L4 when it passes between them. The coils are mounted on arms 61, the angles of which may preset by external levers 47, 49 and the ends of the arm are bent over at 63 to read against an end scale. Zero adjustment is provided on the meter, and the indicator is counter balanced. Coils L1, L2 Fig. 3 are connected in the tank circuit of a transistor Colpitts oscillator TR1, and the signals received in coils L3, L4 in the absence of the vane, when rectified, cut off transistors TR2, TR3 by setting up a positive potential on the bases thereof in opposition to the negative battery. An output signal is thus generated when the meter reads a desired upper or lower value.
