In the case of an oil cargo tank the flaps may be biassed by weights (84) and the flaps may have openings closed by weight-biassed flaps, one of which opens on excess pressure in the tank and the other on under-pressure on emptying the tank. Alternatively internal spring-closed solid metal plates close the openings. A flame screen (70) may be positioned in the duct below the framework.

Abstract: 1293669 Selective embossing DYMO INDUSTRIES Inc 10 Nov 1970 [10 Nov 1969] 53438/70 Heading B6F Strip feeding arrangment.-A hand-held, hand operated embossing tool is provided with a mechanical linkage between a cartridge 74 having strip material coiled therein and the trigger mechanism 20 that effects embossing, so that the entire cartridge is retracted a precise distance away from the embossing station as the trigger is squeezed. During such retraction, the strip end, extending from the cartridge, is restrained by a one way catch pawl 66. In this manner a precise length of strip is pulled from the cartridge. Release of the trigger 20 will cause the cartridge to be pulled forward to its former position. Since a pawl (100, Fig. 2) attached to the cartridge prevents ingress of the strip, this forward motion of the cartridge 74 causes the strip to be advanced through the embossing station The mechanical linkage between the trigger and the cartridge compresses a cam 106 and a cam follower pin 94. Raised ribs 90 on the cartridge co-operate with guide rails on the inside surface of the embossing tool casing to provide for the to and fro movement of the cartridge 74. Transverse cutting.-A trigger 36 pivoted about the same axis as trigger 20, has an anvil 44 which co-operates with a pair of knives 48 disposed on a mounting bracket 50.
