Title: Manufacture of cellular board structures
IPC: B29C65/50
Filed: 1961-05-26
Abstract: 977,630. Laminates and laminating. H. L. LORENTZEN. May 26, 1961 [May 27, 1960], No. 19179/61. Heading B5N. A honeycomb or like cellular board structure in which the axis of each individual cell extends at an angle of substantially 90 degrees to the surfaces of the board, obtained by joining sheets or webs of fibrous material along linearly defined areas, the said sheets or webs being impregnated with and joined to one another by means of one and the same hardening plastic such as a polyester solution, is characterized in that, in order to ensure that joining is restricted to predetermined areas extending stripwise, strips of foil material, which may be coiled, are inserted between the layers of sheet or web material. The foil may be of paper, metal or plastic. At least one fibrous string may be inserted in each of the stripwise jointing areas, parallel to the length of the joint, to fill out the increased spacing between each pair of sheets or webs resulting from the insertion of the foil. As shown (Fig. 2) sheets 11 of glass fibre fabric are superimposed with the interlaying of spaced strips 12 of coiled aluminium foil alternating with a suitable number (here 2) of yarns 13 of glass fibres. The structure is then impregnated with a hardening plastic, which may be accompanied by heat and/or pressure, whereby the sheets 11 are united by the plastic along striplike areas 14 while the strips of foil 12 prevent continuous joining of the sheets. By applying stretching forces to the structure, as shown by arrows in Fig. 2, a honeycomb structure, as shown in Fig. 3, is attained. The foils 12 may be withdrawn from, or dissolved out of, the cells. Irrespective of removal or not of the foils 12, the expanded cells may be filled with a liquid plastic which, upon hardening, forms a foam. The structure of Fig. 3 may be provided with a covering layer parallel to the plane of the drawing to cover the honeycomb cells at either or both ends. The assembly of Fig. 2 may be produced as shown in Fig. 4 wherein sheets of glass fibre fabric 11, coiled foils 12 and glass fibre yams 13 are fed, over guide rolls 22, on to winding drum 21 and are sprayed with impregnant from nozzles 23. When the desired number of layers has been wound on, the assembly can be hardened on the drum. The glass fibre fabric 11 may be omitted and instead glass fibres, plastic and a catalyst may be sprayed from nozzles 23. After hardening, the body may be removed from drum 21 and sliced into axially parallel pieces.

Abstract: 723,090. Automatic firearms. MINISTER OF SUPPLY. Aug. 21, 1952 [Aug. 22, 1951], No. 19763/51. Class 92(2). An automatic firearm comprises a recoiling breech-block 14 which itself incorporates a spring-loaded sear 22 adapted to control the firing pin 16, the breechblock being fitted also with a catch 25 so arranged as to prevent the energy of the spring 7 of the gas piston 6 being applied to the breech-block locking means, such as levers 19, 20 during the axial travel of the breech-block. When the piston 6 of the gun shown is moved to the rear, either by hand or by the explosion gases, a lug 6b thereon first slides along a slot 14a in the breech-block, and at the same time by engaging an aperture 15a in a sleeve 15 drags the latter, and with it the pin 16, to the rear of the breech-block against the action of a spring 17. Subsequently a ramp 16c on the pin acts on the tails 19d, 20d, of the levers 19, 20, to move the levers from locking engagement with recesses in the breech casing. The breech-block and the parts 15, 16, thereafter recoil together. During run-out a projection 6c on the gas piston engages the catch 25 of the breech-block until the latter is depressed by a fixed ramp. The piston now has free forward movement relative to the breech-block, and when the latter reaches its foremost position a part 15b of the sleeve 15 opens out the locking levers. Up to this point the firing pin is held by shoulders 19b, 20b on these levers, but is freed when the levers move to the locked position. The firing pin is further controlled by the sear 22, itself controlled by a lever 23 actuated by the trigger. For single shot firing the sear is free to engage and arrest the firing pin, but for continuous fire it rides up the ramp portion of lever 23 out of engagement with the firing pin.
