The softener is preferably water-extractable. A melt-blown non-woven fabric is produced with the cellulose ester as follows: a cellulose ester, cellulose acetate, with a DS of about 1.5-3.0, in particular 1.7-2.7, is mixed with softener in a weight ratio of about 2:1 to 1:4 and simultaneously heated and melted. The mixture of softener and cellulose ester has a melting index MFI (210/2.16) according to DIN 53 735 of about 400 to 5 g/10 min., in particular 300 to 50 g/10 min. The melt is worked in a melt-blown spinning device into a melt-blown non-woven fabric and the softener is then extracted with a softener solvent to leave a proportion of 0-10 wt. %.

Abstract: The perfected closure device comprises rings (2) and screws (3) which are formed with a single presswork operation together with the strip (1) to be placed at the disposal of the user. The latter with a simple coin screws screws (3) within suitable orifices formed on strip (1), the latter being fixed to the internal surface of the folder. There is also provided that each ring (2) may be closed simply by causing projections (5) which are formed on the base of each ring to penetrate within shaped grooves (4), the latter being formed at the opposite end of the same ring, an operation which is easy due to the elasticity of the material which constitutes the rings.

Abstract: An improved heating torch including a barrel, a top mounting, a gas release device, a flame device and a casing unit. After assembly, by turning a switch button, the flow of fuel gas and initiation of a piezoelectric device to start ignition may be controlled. Two copper sheets which retain a regulating sponge therebetween regulate the pressure of fuel gas for maintaining a stable pressure. The reciprocating movement of a control core conceals or opens a connecting hole for regulating gas flow. A ring notch and a corresponding air vent controls the mixture of air and fuel gas. A front end of the heating torch may further be provided with a soldering-iron, and a base plate is provided on the bottom of the barrel for keeping the torch in a stable position.

Abstract: For connection of a series of balusters to a top rail, each baluster is provided with a pair of jaws extending upwardly from its top end. The top rail has an integral retainer ridge formed lengthwise on its bottom surface. The retainer ridge includes a pair of shoulders having transversely registered pairs of recesses at prescribed longitudinal spacings. A pair of grooves are formed lengthwise in the respective lateral surfaces of the retainer ridge, and another pair of grooves are formed lengthwise in the bottom surface of the top rail on both sides of the retainer ridge. The jaws of each baluster are inserted into the respective grooves in the bottom surface of the top rail via the respective recesses, and the mid-portions of the jaws are then caused to project into the respective grooves in the lateral surfaces of the retainer ridge by pressing operation. The balusters can likewise be connected to a bottom rail.
