Title: Cooling arrangement
IPC: B64G1/50
Filed: 1967-06-23
Abstract: 1,149,145. Artificial satellites. HUGHES AIRCRAFT CO. 23 June, 1967 [25 July, 1966], No. 29144/67. Heading B7W. [Also in Division G1]. A radiation detector for use in a spacecraft, is cooled by an arrangement of shields each provided with a black body radiation surface. In the arrangement of Fig. 1, the detector 14 is mounted, at the end of a tube 12 of heat conductive material and-provided with a plate 10, having- a black body surface, attached to the other end. The tube 12 and detector are surrounded by two shields 15, 25 comprising cylindrical members 22, 32, having annular parts 16, 26 and walls 18, 28 carrying black body surfaces 20, 30. The outer casing 36 by which the arrangement is attached to the space craft (e.g. a satellite) is provided with an aperture 45 through which the radiation to be monitored reaches the detector 12. Filters 24, 34 may be provided at the bottom ends of cylinders 22, 32 and arrange that the radiation reaching the detector is in a particular spectral band. The shields, casing and tube 12 are maintained in spaced and insulated relation to one another by thin stainless steel support wires 50, 52. The tube 12, shields and casing may be of copper, gold-plated to give a highly polished radiation reflective surface. In operation, the black body surfaces 10, 20, 30 are directed towards dark space and shielded from direct sunlight. Radiation from space received by the casing 36 is re-radiated to shield 25. Heat in this shield is dissipated by surface 30 so as to lower the temperature of this shield with respect to that of the casing 36 but some is reradiated to shield 15. Since more heat is dissipated by surface 20, little radiation reaches tube 12 which is able to conduct heat away from the detector 14, which heats up during operation, and the larger surface 10 dissipates this heat. In the arrangement of Fig. 2 (not shown), the shields and casing are generally conical in shape as is the member (62) carrying the detector (64). A further arrangement, Fig. 3 (not shown), dispenses with the support wires and uses solid insulation (layers of glass wool and aluminium foil or aluminized layers of plastics insulating material) between the shields.

Abstract: 750,278. Beams. BROSENIUS, K. H. Oct. 11, 1954 [Oct. 14, 1953], No. 29221/54. Class 20(4). A wooden beam comprises two laths 1, 2, each of triangular cross section glued together at an overlapping contact surface 3 adjacent an acute angle α of the section not more than 28 degrees and preferably between 10 and 20 degrees. The laths can be cut from rectangular rails or the log and assembled so as to counteract warping and bending tendencies. Thus triangular laths 9b, 9c, 10b, 10c, cut from rectangular rails 9, 10, are made into spliced beams of laths 9b, 10c and 9c, 10b so that notwithstanding a drying deformation shown by the curved signs the beam supporting edges 11, 12 remain parallel. In glueing the laths to one another pressure may be applied to the end surfaces 4 by means of wedges inserted into registering recesses cut out of the centre angle edges of both laths.

Abstract: 1,197,891. Cyclonite. MINISTER OF TECHNOLOGY. 30 Sept., 1960 [26 Aug., 1959], No. 29255/59. Heading C2C. [Also in Division C1] The shock sensitivity of the crystalline explosive cyclonite (cyclotrimethylene trinitramine) is increased by heating the cyclonite to a temperature between about 140‹ and 180‹ C. Small amounts of decomposition products accumulate in the lattice and sensitize the explosive. The heating period may range for example from 6 hours at about 180‹ C. to about 2 days at about 140‹ C. A shallow layer of the dry cyclonite may be heated or the explosive may be refluxed with butyl Cellosolve (Registered Trade Mark) or glycerine-water. The treated cyclonite may be mixed with trinitrotoluene or with paraffin liquid, lithium stearate, and pentaerythritol dioleate to form composite explosives.

Trench-excavating rotary cutting heads, such as shown at 38a and 38c may be provided at either side of the arms 22, 23 so that the machine can be effectively operated in either direction of travel along the pipe. These cutting heads together with further cutter heads such as 44a, 44c are driven by hydraulic motors such as 46a, 46c. There can be associated with the cutter heads jetting nozzles and suction means for removing spoil from the vicinity of the cutter heads, the nozzles and suction means being incorporated in or associated with the arms 22, 23. Buoyancy chambers are mounted on the structure 12 to allow of reduction of the dead weight of the machine on the pipe.

Abstract: 764,860. Stuffing-box substitutes. NAPIER & SON, Ltd., D. Oct. 13, 1954 [Oct. 26, 1953], No. 29590/53. Class 122 (5). [Also in Group XXXIV] A bearing assembly comprises at least one bearing of the ball or roller type, sealing means of the labyrinth type between the inner and outer members on each side of the bearing forming an annular chamber, means comprising a metering orifice for delivering lubricating oil at a controlled rate through a nozzle on to the bearing, and means for continuously withdrawing fluid from the chamber at a volumetric rate higher than that at which oil is delivered to the chamber, and an interconnecting passage or the equivalent between the spaces on the sides of the sealing means remote from the bearing, so as to tend to equalize the pressures in these two spaces, thereby tending to maintain a continuous flow of fluid inwards past both sealing means towards the bearing. The invention is described as applied to a bearing supporting a common turbine and compressor shaft in an aircraft gas turbine propulsion unit. A sealing disc 15 mounted on the compressor shaft 11 is provided with flanges 16, 18 which cooperate with parts of the casing 20 to constitute labyrinth type seals preventing compressed air from passing inwardly towards a housing 21 for a roller bearing 36. A cylindrical liner 22 secured within the housing is provided at one end with a flange 23 and at the other end with a clamping ring 24 for holding in place labyrinth sealing members which comprise a sealing member 26 co-operating with a sealing member 28 on the shaft 11, sealing members 29, 31, co-operating with a sealing member 30 on the shaft 11, and a sealing member 33 co-operating with a sealing member 34 on the shaft 11. Chambers 47, 48 are interconnected to be at the same pressure. Oil is supplied to the bearing from a tank by a displacement pump 65 in parallel with a pressure relief valve 66, the oil passing through passages 64, 63, 62, 60 and through inclined nozzles of small cross-sectional area. The oil is withdrawn through passages 51, 52, 53 by a positive displacement vane type pump 54 associated with an air separation chamber. The volumetric rate of withdrawal of fluid by the pump 54 is considerably in excess of the volumetric rate at which oil is supplied through the nozzle passages 60, so that there is a continuous flow of air inwards past the labyrinth sealing means towards the bearing to prevent loss of oil.
