Abstract: 330,730. British United Shoe Machinery Co., Ltd., and Hazelton, G. May 16,1929. Affixing tape.-A machine suitable for applying adhesive tape to the back seams of boot or shoe uppers while the seam is on the inside of the workpiece comprises devices, including a roll, between which the workpiece is fed with the seam facing the roll, the tape being fed between the workpiece and the roll. In the form shewn in Fig. 5, both devices are in the form of rolls, one roll 17, having a transversely convex periphery, being driven from a shaft 32 through a worm and reduction gear on shafts 29, 25, and being provided with a cover 55. The other roll 35, the periphery of which is concave, is carried by arms 37 connected with a spring-influenced spindle 42 pivotally supported by a pin 44, and adjustable to and from the roll 17 by a screwed head 48; the pressure on the spring 47 can be varied by adjusting a sleeve 43 surrounding the spindle 42. The arms 37 are mounted on an eccentric which is carried on a shaft 39 and is rotated by a pulley 40; by these means a vibratory motion is imparted to the roll 35. A transverse pin 60 is carried by an arm 71 adjustably mounted, under the influence of a spring, on an arm 73, the other end of which is connected, by a link 77, with a pedal, the operation of which raises the pin 60, a stud 78 on the arm 73 simultaneously effecting the raising of the arms 37 carrying the roll 35. The pin 60 presses on the upper side of the work, as shown in Fig. 8, and squeezes it against a bridge piece 57, which is carried by the cover 55, and under which the tape is led, adhesive side upwards, from a supply roll on the machine frame. The cover 55 is furnished with a groove to guide the tape, and the bridge piece 57 with a notch to take the upturned seam. In another form, an endless band, passing over pulleys with concave peripheries, is used to press the workpiece and tape together. Part of the length of the band is in contact with a pulley having a convex periphery; a pressure roll may be provided at this point. Specifications 272,183, 297,349 and 318,907 are referred to.

Filed: 1949-06-09
Abstract: A mono-quaternary ammonium tri-alkali metal salt of ethylene diamine tetra-acetic acid in which the quaternary ammonium cation is an alkyl, preferably C12 to 14, dimethyl benzyl ammonium radical, is prepared by dissolving 1 mol. ethylene diamine tetra-acetic acid in an aqueous solution containing 1 mol. of the quaternary ammonium hydroxide and adding 3 mols. sodium hydroxide. The salt may be obtained by evaporating the solution to dryness.ALSO:A germicidal detergent composition for use with hard water in industrial cleaning operations, consists of a mixture containing 10 to 30 per cent by weight of an alkali metal salt of ethylene diamine tetraacetic acid, up to 25 per cent by weight of a germicidally active quaternary ammonium salt of ethylene diamine tetraacetic acid and a balance consisting of an alkali metal detergent salt selected from the alkali metal phosphates, carbonates, silicates, borates and sulphates, or a mixture thereof.  Within the above limits, the per cent of ethylene diamine tetraacetate is varied according to the hardness of the water and the per cent of quaternary salt according to the desired germicidal activity.  A mixture suitable for use in water of medium hardness consists of 20 per cent tetra-sodium salt of ethylene diamine tetraacetic acid, 20 per cent mono-quaternary ammonium tri-sodium salt of ethylene diamine tetra-acetic acid and alkyl dimethyl benzyl ammonium hydroxide, and 60 per cent sodium carbonate. The sodium carbonate may be replaced by (a) di- or tri-sodium phosphate, or mixtures thereof (b) di- or tri-sodium phosphate and sodium silicate, preferably in the ratio of 10 parts phosphate to 1 part silicate, (c) sodium sulphate, wholly or in part.  The preferred quaternary ammonium compounds are those having an alkyl chain of 12 to 14 carbon atoms and these may be combined with ethylene diamine tetraacetic acid to form the mono-to tetrasalts thereof.  For pH below 10, the pH of the detergent mixture may be varied by substituting for the tetra-sodium salt of ethylene diamine tetraacetic acid various proportions of the di- and tri-sodium salt of the tetraacetic acid.

[Class 36] In a metal-sheathed multi-conductor highfrequency communication cable the influence of the metal sheath on the outer circuits of the cable is compensated by employing in the circuits adjacent the sheath conductors whose direct current resistance is lower than that of the conductors of the inner circuits by such an amount that at a specified frequency within the range of frequencies over which the cable operates the alternating current resistances of the inner and outer circuits are substantially equal. The compensation is preferably effected by making the conductors of the outer circuits of larger diameter than the conductors of the inner circuits so as to increase the inductance of the outer circuits, but compensation may also be effected by the use of conductors of different conductivity for the inner and outer circuits. 444,880.
