A captive screw closure for containers has an opening in its end wall which is closed by a pin 6 when the cap is screwed down. An annular bead 3 on the inner wall of the cap can engage with axially offset but diametrically opposed cams 12 and 13, preventing the cap from being freed while it is being unscrewed. The slight clearance between cap and bottle neck threads enables the cap to be tilted during initial fitting so that bead 3 can slide over each locking cam 12 and 13 in turn, even if cap and neck were made of quite rigid material. The chamfered upper faces of the cams 12a, 13a, Fig. 3 (not shown), and the triangular cross-section of the bead 3 facilitate this initial fitting.

Title: Improvements in or relating to the finishing of wool or wool-containing textiles
IPC: D06M15/423
Filed: 1946-05-13
Abstract: Woollen textiles are rendered resistant to shrinking and are also rendered permanently resistant to attack by insects by impregnating them with a finely-divided water-insoluble insecticide and then with an aqueous solution of an alkylated methylol melamine resin and subsequently heating them to cure the resin therein to a water-insoluble condition, whereby the insecticide is retained on the textiles in a laundry-resistant condition.  The insecticide may be dissolved in an organic solvent and padded or sprayed on to the textile material, the solvent being then removed by evaporation.  The alkylated methylol melamine may be employed in quantities of 2-15 per cent of the dry weight of the textile material, and the insecticide may be used in amounts of 0.15-10 per cent.  Acetone may be used as solvent for the insecticide.  The insecticide may be a dichloro-di-phenyl trichloro-ethane ("D.D.T."), or similar halogenated diaryl-substituted alkane, or it may be calcium fluoride, or calcium silicofluoride.  Specifications 547,874 and 562,977 are referred to.

A process for stretching a polypropylene film comprises passing said film through a stretching zone and stretching consecutively adjacent widths of said film transversely to the direction of passage of the film through the stretching zone and/or transversely to the direction of the prior stretching, the temperature of the width being stretched at any one instant, being below the melting point of the film but at least high enough to enable the film to be stretched, the breadth of each width being from 7 mm. to 250 mm. and the average temperature of the width being stretched being at least 7‹ C. higher than the temperature of th film immediately adjacent said width. Preferably the film is first subjected to preliminary heating and the width being stretched is subjected to a localized heat radiation, the average radiation breadth of the radiation being from 7 mm. to 250 mm. The temperature of the width being stretched may be decreased from the heat radiation marginal line on the film feeding side of said width. Preferably the temperature differential across said width being stretched is at least 3‹ C. and the breadth of the width being stretched is from 10 mm. to 200 mm. Preferably the film is stretched transversely to the direction of passage of the film through the stretching zone and transversely to the direction of prior stretching. The amount of heat received by the width being stretched may decrease in the longitudinal direction of said width such that the amount of heat absorbed by the part of the width firstly stretched is at least 10% greater than that absorbed by the part of the width lastly stretched. The polypropylene film may contain up to 5% by weight of polyethylene. The apparatus shown in Figure 3 includes an infrared ray heating element 6, surrounded by reflecting plate 7, and screening plate 8 and cooling medium feed and exhaust pipes 9, 9<SP>1</SP>, 10<SP>1</SP> and 10<SP>11</SP>. 11 is a polypropylene film being treated. Reflection plate 7, which comprises a plurality of curved reflecting plates joined together, rests on screening plate 8, which is provided with an adjustable slit 12 disposed opposite the heating element 6. By means of the flow of cooling medium the screening plate 8 never becomes heated. Therefore there is no heat radiation from this part and the slit 12 in screening plate 8 is adjustable so that it is possible to heat only a linear or belt-like area of the film. The disposition of the heaters in relation to the transverse direction of the film may be straight, V-shaped, reverse V-shaped or L-shaped.
