Abstract: 1415538 Coated sheet materials CARL FREUDENBERG 15 Dec 1972 [18 Dec 1971 4 Feb 1972] 57991/72 Heading B2E [Also in Divisions Dl and D2] An interlining material in the form of a continuous length of a bonded non-woven fabric optionally carrying a coating of heat-activatable adhesive, has areas having a minimum dimension in the area of the fabric of 1 cm. preferably 5 cm which comprise differing concentrations. of binder and/or adhesive. As shown area 3 contains more binder than area 2. Interlinings are cut from the fabric having one area comprising more binder and hence stiffer than the other area. In other embodiments three zones of differing concentration of adhesive coating run the length of the continuous fabric. Preferably the interlining is hot pressed onto the outer fabric e.g. a man's jacket. Alternatively it is sewn, prepared from a 55 g/m<SP>2</SP> carded, orientated fleece of crimped polyamide fibres of thickness 3 denier, length 5 cm and 22 crimps/cm. A foamed nitrile rubber latex is uniformly applied to the fleece, forced in by pressure rolls and the rubber partially cured at 120-140‹C to give an 80 g/m<SP>2</SP> bonded fabric. Additional nitrile rubber latex, thickened with methyl cellulose is then applied as a paste to a stencil having longitudinal slots as the stencil masks the fabric to form longitudinal ridges that are calendered into the fabric. Alternatively the binder may be applied by a grooved roll. In the embodiment of Fig. 2, not shown, this additional binder covers half the fabric as longitudinal rows. The first and second binders are cured at 140-160‹C. A heat activatable adhesive is then applied to the opposite surface to that at which the binder is applied particles of polyolefine may scattered onto the surface or an aqueous polyamide dispersion may be printed as discontinuous rows, the rows being closer together in some areas than in others. Alternatively the printing roll may have grooves which decrease steadily in depth so that the concentration of adhesive varies along the rows.

Abstract: 1377767 Caps for bottles OWENS-ILLINOIS Inc 20 Dec 1971 [18 Dec 1970] 58964/71 Heading B8T A metal closure cap 21 for a container comprises a top portion 22 with a depending skirt 25 having a rolled edge 26. Scored in the cap is a V- shaped tear strip 13, with a small radius nose 14, diverging sides 15, 15a, and unequal length terminal legs 16, 16a, such that one leg 16 extends through the rolled edge 26 of the skirt and the other leg 16a terminates on the skirt with a segment of reversed curvature 18, a diametric hinge score 12 extending from the nose 14. The area of tear strip 13 is more than half the area of the cap and the nose portion 14 is situated substantially beyond the centre of the top portion 22 on the opposite side to the legs 16, 16a. A ring 20 is connected by a tongue 27 to a rivet 19 integral with the nose portion 14 of the tear strip 13. When affixed to a container the closure cap 21 has a plastic gasket liner with a vent aperture. Upon lifting ring 20 the front end of the ring engages the-top panel 22 outside the tear strip 13 and acts as a fulcrum, initially rupturing nose portion 14 to vent the internal pressure. Further removal of tear strip 13 weakens the cap and breaks the rolled edge 26, though it is retained at the shorter leg 16a, 18. Thereafter further pulling splits the cap 21 open about hinge score 12 and frees the cap from the container mouth.
Patent GB-596253-A (GB)
Abstract: 596,253. Gun-fire interrupters. BOX. NELL, R. P. July 18, 1945, Nos. 18474 and 18475. [Class 92 (i)] To avoid hitting parts of the surrounding structure a gun is provided with an interrupter device comprising a disc or the like carrying profiles of the surround and with a member operatively associated with the disc to control the firing circuit, the disc and member moving in a definite ratio to the movements of the gun in training and elevation when the gun is moving at constant speed, and means being provided to retard or advance the disc or member on any variation in the speed of the gun. In the construction shown, azimuth movements of a gun turret rotate a shaft 1 leading to a differential gear, the output shaft 6 of this gear carrying a disk 7 which carries insulated images 7a, 7b, or alternatively raised or sunken portions representing portions of the structure in which the turret is mounted. The shaft 1 also drives a shaft 13 leading to a second differential gear whose output shaft 18 is subjected to the braking action of a pawl 20 which co-operates with an excapement wheel 19 on the shaft. The bevel wheels 4, 5 of one differential and those 16, 17 of the other are carried on spindles 8, 22, which are mounted in housings, Fig. 2 (not shown), and these housings have integral extensions 9a, 23, respectively, which carry mutually intermeshing toothed racks 10, 24. Springs 25 tend to maintain spindle 22 in alignment with spindle 8. In use, if shaft 1 rotates at a constant speed then the disk 7 rotates in synchronism, the differential gear on shaft 13 being idle. If shaft 1 is speeded up then, due to the inertia of the escapement mechanism the shaft 13 will advance relatively to the shaft 18, thus causing the housings of the differentials to move with a consequential advancement of the angular position of the disk 7 with respect to the shaft 1. Thus with the turret rotating at the increased speed the images will be contacted at an earlier stage by the brush 26 in the firing circuit of the gun. Similarly, if the speed of the turret is reduced, the disk will be moved in the opposite direction with respect to the shaft 1. Elevating movements of the gun are transmitted to a shaft 27 associated with mechanism similar to that described above, such mechanism serving to drive a disk 34 formed with a slot 35 in which the brush 26 is engaged. This slot may be of constant radius for part of its length but varies in radius at other parts to move the brush with respect to the images on the disk 7.
