Title: Improvements in reservoir fountain pens
IPC: B43K5/06
Filed: 1931-04-02
Abstract: 375,457. Fountain pens. VIVIAN, G. S., 237, Norbury Crescent, Norbury, London, and FORD, Ltd., T. B., Snakeley Paper Mill, Loudwater, High Wycombe, Buckinghamshire. April 2, 1931, No. 10119. [Class 146 (iii).] A self-filling fountain pen comprises a tubular transparent reservoir 2 having at its opposite ends the nib-section 4 and a relatively-movable operatirig-cap 12 for the selffilling mechanism extending beyond the end of the reservoir, and a sheath 1 extending completely over the reservoir from the nibsection to the cap. The sheath may be of vulcanite, metal, or other material or composition and may be held in place frictionally or by screwing. If formed of metal, the sheath is preferably provided with perforations arranged in the form of an ornamental design so that the amount of ink in the reservoir can be seen without removal of the sheath. The cap 12, which is preferably associated with self-filling mechanism of the type described in Specifications 337,794, 337,835, [both in Class 146 (iii), Writing- appliances &c.], and 359,230, is slidable on a bush 13 projecting from the reservoir and is formed with a screw-thread by means of which it is attached to the sheath. A spring 16 is mounted between the bush 13 and cap 12. The sheath is formed with an internal shoulder 18 adapted to be drawn into engagement with a ledge at the junction of the reservoir and nibsection. The reservoir may be reinforced at the front end by a metal band 22 clamped round the reservoir, the nib-section being inserted into the reinforced part. A nibcovering cap is provided which may screw on to the end of the sheath or, as shown in Fig. 3, may be formed integral with the sheath, in which case the reservoir is uncovered each time the cap is removed for use and is so formed that the sheath can be applied from either end. The cap is preferably formed with a concentric tubular section 7 to contact with the end of the nib-section and so prevent ink from leaking on to the exterior of the reservoir and sheath. The section 7 is detachable, and a pocket-clip 21 may be secured in place between the section 7 and the main part of the cap.

Abstract: 219,372. Wain, J. R. April 18, 1923 Tension arrangements; thread guides; building-motions.-To avoid excessive tension in the yarn as it is being wound on the nose of a cop in a ring spinning or ring doubling machine when spinning on the bare spindle or on a short tube, the yarn is retarded when winding on the larger diameter of the cop and the yarn so taken up is paid out when winding on the nose. At each side of the machine a glass, porcelain, or like longitudinal rod a is carried on arms b fixed upon a shaft c, upon which are also fixed short arms h coupled to links i carried by a lever j pivoted at k. The lever j carries a bowl n coacting with a can r fixed on the shaft o of the usual lifting-cam p, and is rocked therefrom so as to raise the rods a during the winding on the larger diameter of the cop and to pay out the retarded yarn when winding on the nose. A step t is provided on the cam r to give a quick drop at the nose of the cop, and the cam p is provided with a similar step u, the drops on the two cams coming into action about the same time, a little lead preferably being given to the step t.

Abstract: 1411727 Polyisocyanate polyaddition products BAYER AG 13 March 1974 [13 March 1973] 11166/74 Heading C3R Branched polyisocyanate polyaddition products having a M.W. of 464 to 18,000 are prepared by reacting (1) a polyisocyanate component which comprises at least one polyisocyanate which contains a uretdione group, and (2) an active hydrogen group-containing compound, such that the equivalent ratio of active hydrogen-containing groups to NCO groups is 1.07 : 1 to 2.5 : 1 and the product contains 0.6 to 25% by weight of uretdione groups and has a functionality, based on the number of end groups which are capable of reacting with uretdione groups, from 2.05 to 10. The component (1) may comprise a polyisocyanate which contains a uretdione group in admixture with a polyisocyanate free from uretdione groups. The active hydrogen-containing compound may be a low M.W. polyol, an aminoalcohol, a polyamine, a polyester polyol or a polyether polyol. Compounds containing hydroxyl groups are particularly preferred. Reaction may take place in solution or solvent-free medium and in the presence or absence of catalysts. The products may be produced in the form of powders suitable for powder coating. On heating at temperatures greater than 110 C. the powders self cross-link. Particulate polyhydroxy compounds, e.g. polyesters may be mixed with the powders before cross-linking. In a typical example, a branched polyester derived from adipic acid, phthalic acid, propane-1,2-diol and trimethylolpropane, admixed with trimethylolpropane is mixed with the product derived from 2-ethyl hexane-1,3-diol and tolylene diisocyanate and reacted and the resulting product is reacted with a uretdione diisocyanate derived from tolylene diisocyanate. The resulting resin may be sizereduced and mixed with titanium dioxide to form a powder coating or may be dissolved in acetone and painted on a metal substrate.

Filed: 1917-08-03
Abstract: 128,606. Mauclaire, L., Garbarini, A., and Gautier, G. Aug. 3, 1917. Arc lamps.-In a device for lighting or for generating electric oscillations, an arc between an annular electrode B and an axial electrode C is rotated electro - magnetically by two circular coils O<1>, O<2> in front of and behind the arc. The field thus produced checks wandering of the arc from its normal zone. One coil may have a stronger action than the other; for instance, the front coil O<2> may comprise 3 turns and the rear coil 5 turns. Combustion of the axial carbon C is retarded by a capped body A backing the space between the electrodes and made of refractory material faced with rare earths and thoria. Fumes are exhausted through a. passage x in the axial electrode. If the electrode has a central core, this may be tubular, or several small passages may be grouped around the core. Soiling of lenses is thus prevented, and the carbon is thoroughly dried. The annular electrode may be of metal and water-cooled.
