Title: Protective shield structure
IPC: G21F5/10
Filed: 1965-10-29
Abstract: 1,120,397. Shielded containers for radioactive material. NATIONAL LEAD CO. 29 Oct., 1965 [6 Nov., 1964], No. 45965/65. Heading B4Q. A lead container for transporting radioactive material is protected against an external fire hazard by means of a surrounding shield having a heat insulating wall spaced from the container. Air inlet and outlet means in the shield normally permit a circulation of air over the container to provide a cooling effect but in the event of a rise in the external ambient temperature above a predetermined amount air flow control means in the shield stop the air circulation. In one embodiment, Fig. 2, a container 50 mounted by trunnions 64 on a base structure 27, 28 on a lorry transporter (Fig. 1, not shown) is protected against fire by a shield 80 (shown in its raised position). The shield comprises a metal framework (Fig. 10, not shown) clad with thermal insulation material, e.g. reacted calcium silicates. This material is held between sheets of expanded metal and covered on the exterior with aluminium sheet acting as a heat reflector (Fig. 11, not shown). The air enters under the bottom edge of the shield 80 and leaves through an opening at the top. Immediately prior to its exit the air passes through passages formed by annular members 160, 162, 164 coated with intumescent paint (Fig. 6, not shown) whereby in the event of rise in temperature above a certain level the paint swells and blocks the passages to stop the air flow. In another embodiment (Figs. 12-18, not shown) a container 426 is surrounded in spaced relationship by a U-shaped shield 440 having air inlets 450 and air outlets 452. The inlets have shutters 490 biased to the closed closed position by springs 510 but normally held open by shear pins 500 of a low melting point alloy. At a predetermined temperature the pins melt and the shutters close to stop the air flow. The thermal insulating property of the wall of the shield is obtained by making the wall of spaced sheets 520 of stainless steel.

Abstract: 924,078. Jet propelled aircraft. ROLLSROYCE Ltd. Dec. 22, 1961, No. 46111/61. Class 4. An aircraft has at least two main forward propulsion jet engines, and at least one additional forward propulsion jet engine of substantially greater thrust/weight ratio than the main engines, the arrangement being such that if one main engine fails, the thrust available from the remaining main engine(s) is less than that required for take-off, the necessary additional thrust being available from the additional engine(s). The aircraft of Fig. 1 has three main gas turbine engines, each of 10,000 lb. thrust and thrust to weight ratio of 5: 1. Two engines are installed in pods such as 18 on the fuselage rail, and the third engine 15 is buried in the tail, having an air intake 21 and jet pipe 22. An additional gas turbine engine 23, of 4,000 lb. thrust and thrust/weight ratio of 16: 1, is buried in the tail, having air intake duct 24, intake closure door 25, jet pipe 26, and outlet vanes 27. Any two main engines with engine 23 can thus provide the 24,000 lb. take-off thrust, and any two main engines alone can provide the 18,000 lb. thrust required during cruise. The additional engine may have a bifurcated inlet duct leading from laterally spaced intakes. The aircraft may have two main engines mounted on opposite sides of the fuselage and one additional engine buried in the tail. Provision is made for starting the additional engine by air bled from the compressor of a main engine, and vice versa. The wings are as small as is consistant with satisfactory landing performance, this being assisted by unspecified flap-blowing and boundary layer control devices operated by air bled from the main engines. The additional engine may drive a generator and supply air to cooling units when the aircraft is on the ground or flying at low speed, and may drive a hydraulic pump to provide power operation of the flying controls. All engines may be used for normal take-off, and only the main engines thereafter.

Abstract: 1,016,198. Jet propulsion nozzles. GENERAL ELECTRIC CO. Nov. 29, 1963 [Dec. 3, 1962], No. 47228/63. Heading F1J. The invention relates to a propulsion nozzle of a jet propulsion engine, the nozzle comprising an inner plug member in the form of two frustoconical members which abut base to base, the plug member being formed of two sets of flaps, the upstream set being pivotally mounted at their upstream ends and the downstream set being pivotally mounted at their downstream ends, means being provided for adjusting the positions of the flaps so as to vary the diameter of the plug member and hence the area of the throat of the nozzle. The nozzle assembly comprises a central support tube 37 which is secured at 36 to a tube 12 of similar diameter, the tube 12 being the frame member of a gas turbine jet engine (not shown). A first set of flaps 30 is pivotally mounted on the tube 37 at 34, the flaps together defining a frusto-conical surface which together with the outer wall 10 of the engine exhaust duct defines a convergent portion of the propulsion nozzle. A second set of flaps 32 is pivotally mounted at the downstream end of the tube 37 at 50, the flaps together defining a frusto-conical surface. The adjacent flaps of the two sets are connected together by means of cam slot and slider arrangements 38, the curved forward ends of the flaps 32 defining together with the inwardly curved surface 23 of the outer wall 10 the throat 26 of the propulsion nozzle. The flaps 32 are connected by pivoted links 56 to an axially-movable cup-shaped member 62 whereby the positions of the flaps 32 and 30 may be varied and hence also the diameter of the plug member. The position shown in Fig. 2 in which the area of the annulus C is a minimum is that assumed for subsonic flight and that of Fig. 3 (not shown) in which the area of the annulus B is a maximum is that assumed for supersonic flight. The cup-shaped member 62 is mounted for axial movement within the tubular member 37 by means of frusto-conical ring members 67, 68 which engage tracks 72 secured within the tubular member. The cup-shaped member 62 is connected by means of a pivoted rod 65 to an actuator 66. Sealing members are disposed between the adjacent flaps 30, 32 of the two sets of flaps. Cooling air is supplied under pressure through the tubular member 37, the air passing through openings 98 into the space 97 within the plug member, the air flowing adjacent the inner surfaces of the flaps 32 and discharging through the pivots 50. A further quantity of cooling air is supplied through the duct 94 around the tubular member 12, this air being guided by a deflector 96 to flow over the outer surfaces of the upstream flaps 30; some of this air also passes through the pivots 34 to flow adjacent the inner surfaces of the flaps 30 and then through the connections 38 into the gas stream.
