Abstract: 1,256,801. Cartons. JOHN WADDINGTON Ltd. 22 Jan., 1969 [8 Feb., 1968; 22 Aug., 1968], Nos. 3618/69 and 3619/69. Divided out of 1,191,108. Heading B8P. A carton erected from a blank to tubular form and having a front, bottom, rear and top with the ends closed subsequently, has an edge part gripped by two other parts of the blank, so that the carton can be opened by withdrawing the edge part from the other two parts and lifting the top as a hinged lid. In one form, a carton is erected from a blank having a top panel 8, Fig. 2, with a depending flange 10, and a front wall 2. An extension panel 12 is secured by glue 18 inside the front wall to lie downwardly, and a further extension panel 14 is secured to the inside of the panel 12 to face upwardly, Fig. 4. The extension panels 12, 14 form a slot receiving and gripping the top panel flange 10. A notch 40 at the top of the front wall 2 facilitates opening the lid 8. Decorative panels 36, 38 extend along the top edge of the carton. The carton is made in flat form, with the top panel flange 10 inserted into its slot 12, 14. It is erected to tubular form, filled, and closed by glueing end flaps 30, etc. In a modification, the extension panels (12, 14), Figs. 5, 6 (not shown), are of narrow depth compared to the depth of the front wall 2, and tabs (90) at the ends of the extension panel 14 are glued to flaps 32 on the carton end walls. In another embodiment, the top flange 10, Fig. 7, has notches 94 which are engaged with notches 98 in the front wall 2, the upper part of the top flange lying outside the front wall, and the lower part 92 lying inside the front wall, Fig. 8 (not shown). In yet another modification, the top flange has a tab 100, Fig. 9, engaged in a slot 102 at the base of the front wall 2, the upper parts 104 of the top flange lying outside the upper parts 106 of the front wall while the lower part 92 of the top flange lies inside the front wall, Fig. 10 (not shown). The top panel 8 has an arcuate slit 108 and hinge lines 10: the lid can be opened to the vertical position, and the part carrying the top flange 100 folded down through 180 degrees to engage the tab 100 in a second slot 112 adjacent the tear wall of the carton. Printed matter previously seen on the top panel 8 is then visible from the front of the carton, which can be used for display. The carton may be initially wrapped in transparent material. The gripping means of Figs. 7, 8 may be used with cartons having tucked or folded ends opened-out to display the contents.

Abstract: 1289150 Ultra-violet irradiating apparatus DETEC SA 18 Dec 1969 [31 Dec 1968] 61681/69 Heading H5R  Apparatus for purifying and sterilizing premises comprises a hot cathode ultra-violet ray tube 15 and a cold cathode ultra-violet ray tube 16 over which the atmosphere of the premises is circulated by a fan 11, each tube being separately operable and the fan and both tubes being enclosed in a single casing 1. Operation of the fan and the hot-cathode tube 15 alone may purify the premises when they are occupied. However the premises may be sterilized, when they are unoccupied, by operating the coldcathode tube 16 also-this tube also produces ozone which has a powerful "in situ" sterilizing action on the air purified by the hot-cathode tube. As shown, the two tubes 15, 16, separated by a metal screen 25, are mounted parallel to the back wall of casing 1 which has a reflector 22 of metal sheeting deformed to give alternate ridges 23, 24 projecting towards the tubes. The front wall of the casing may be a hinged door 29 lined inside with an undulating reflector 32 and a window 33. The fan 11 draws in air through the slotted wall 4 which then passes over the tubes to the outlet 5.

Abstract: 1334683 Brazing DEFENCE SECRETARY OF STATE FOR 29 Sept 1970 46271/70 Heading B3R [Also in Division B2] A method of brazing two parts together comprises the steps of first applying to at least one of the joint surfaces a permanently tacky adhesive, applying to the outer surface of said adhesive a mono-particulate layer of graded metallic brazing powder, placing the parts together and heat-treating the assembly so that the parts are diffusion brazed together. The adhesive vaporizes off from between the assembled surfaces. Brazing may be effected in vacuo and the parts may be enclosed in an evacuated flexible metallic foil bag. The adhesive may be applied by brush or spray and certain proprietary adhesives are referred to. The metal powder may be applied by dipping the adhesive coated part in a bath or fluidized bed, excess powder being shaken off, or by a brush and the powder may be compacted by a roller. Examples are given in which reference is made to brazing turbine blade parts and to brazing honeycomb material to a coated metal sheet to form a heat- or sound-insulating panel.
