Patent GB-2173250-A (GB)
Title: Weld stud and means for co- operating therewith
Inventor: KONDO YOSHITERU
IPC: F16B21/06
Filed: 1986-03-27
Abstract: For fastening articles to a metal surface a flat-sided metal stud 7 with an aperture 9 and shoulders 10 is welded to the surface and a plastics clip 1 pushed on to it, the clip having resilient latches 13, 16 which co- operate with the aperture 9 and shoulders 10 of the stud to lock the two together and having means for holding the article in position. The base of the stud 7 is shaped as a very shallow V to facilitate welding to the metal surface. The arrangement is especially advantageous where it is desired to secure the article in a particular disposition without the risk of rotation that is involved using a conventional round stud. <IMAGE>

Abstract: A thermosetting resin having high thermal resistance, high strength, flame resistance, and good processability can be obtained by reacting polycarbodiimide substantially produced from one or more kinds of organic polyisocyanate with crosslinking agents having two or more active hydrogen groups in their molecules, one or more kinds of compounds having epoxy groups in their molecules or compounds capable of accelerating the trimerization reaction of carbodiimide. Suitable crosslinking agents include aminotriazine, 4,4'-isopropylidene diphenol, 4,4'-diamino diphenyl methane and derivatives thereof. Suitable epoxy compounds are monofunctional epoxy compounds, e.g. epichlorohydrin, glycidyl ethers e.g. diglycidyl ether of bisphenol A, glycidyl esters or glycidyl amines. The polycarbodiimide may be reacted with a novolac phenolic resin. An organic monoisocyanate may be present during the preparation of the resin.

Title: Impregnating porous carbon bodies
Inventor: FUJIKAWA TAKAO
IPC: C04B41/82
Filed: 1989-07-04
Abstract: A porous shaped body of carbon and a block of impregnant is inserted into a chamber, gas is discharged from the chamber, the impregnant e.g. tar pitch as resin is melted under a reduced pressure and the shaped body immersed in the molten liquid of the impregnant. The chamber is then transferred into a high pressure vessel and high pressure gas fed into the vessel and chamber to penetrate the impregnant into the shaped body of carbon. The body is then heated to a high temperature, and the high pressure gas discharged to lower the pressure within the chamber at a controlled rate in response to a pressure within the high pressure vessel to carbonize the impregnant.
Patent GB-2227817-A (GB)
Title: Sabots
Inventor: SCHLEICHER ULRICH
IPC: F42B14/06
Filed: 1989-12-06
Abstract: A sabot 12 for a subcalibre projectile 10 has with the projectile 10 a common form-locking zone 14. The sabot 12 has, moreover, a gas-pressure absorption surface 24, an air pocket 22 and tension mechanisms 28, 30 for the absorption of tensile stresses which is connected to a central carrier part 16 adjacent to the projectile 10. In order to avoid undesired transverse forces leading to bending loads, the sabot 12 has, apart from the tension mechanism, membrane surfaces 24 which can be stressed in compression, so that mechanical stresses occuring in the sabot 12 are converted only into tensile and/or compression stresses. The tension mechanisms 28, 30 may comprise hair-shaped monocrystals of metals, oxides, borides, carbides, nitrides, graphite or diamond. The material of the sabot may be combustible so that its mass is progressively reduced as the projectile travels down the gun barrel. The form locking zone 14 may be such that, upon passage through a magnetic field at the muzzle of the gun, the mechanical connection between the sabot and the projectile is released. The sabot may be segmented.

Title: Interference-cancelling adaptive antenna system
Inventor: HUDSON JOHN EDWARD
IPC: G01S3/86
Filed: 1990-03-22
Abstract: A broadband adaptive antenna for receiving a signal in the presence of a plurality of interference sources includes an array 11 of N elements 110 one of which is associated with an omnidirectional main signal channel, the remaining (N-1) elements are auxiliary elements whose waveforms are time shied by primary time lags 12 and differenced against the main signal channel to remove the desired signal from them. The (N-1) residues from this operation are passed through sets of further secondary time lags and summers to form a small number of auxiliary beams directed one toward each interference source. The adaptive output of the antenna is formed combining the main channel with the auxiliary beams after passing each of the latter through an adaptive filter. The small number of auxiliary channels required allows a very significant reduction in the computational requirements of the antenna in comparison with a conventional broadband array. <IMAGE>

Title: Method of cutting letter box openings and a template therefor
Inventor: WHITELAW THOMAS
IPC: B27F5/12
Filed: 1990-04-02
Abstract: A template 10 is provided for use in cutting out a letter box opening. It is a flat metal plate having a rectangular opening 11 therein to correspond to the dimensions of the letter box opening to be made. It also has two locating pins 13 extending from one face, one at each side of the opening and above these pins are two guide holes 13' to enable holes to be drilled in a door (12 Fig. 4) at the correct location to receive the locating pins. The pins 13 are hollow and the template is secured firmly to the inside of the door by screws which extend into the pins from the other side of the door. In use, a router cuts into the door guided by the edges of the opening 11. The router blade is set to a depth equal to half the thickness of the door and after that cut has been made, the blade is set to the full depth of the door and the cut completed to separate the cut out portion. The template is then removed and the letter box cover mounted on the door via the holes previously drilled to receive the locating pins. In an alternative method, after cutting a first groove from one side of the door, the template is removed and positioned on the opposite side of the door so that a second groove is cut from the opposite side of the door. <IMAGE>

Filed: 1990-09-27
Abstract: An electromagnetic brake for arresting the rotation of the driving shaft 54 of an elevator comprises two plungers 1a and 1b operated by separate solenoid coils 2a and 2b. When the brake is to be activated, the supplies of excitation currents through the coils 2a and 2b are stopped, so that, urged by the springs 51 via the levers 50, the brake shoes 52 bear on the brake wheel 53 to arrest the rotation thereof. The timings at which the excitations of the coils 2a and 2b are attenuated are differentiated so that the brake shoes 52 bear on the wheel 53 first from one side and then from the other. The differentiation of the attenuation times of the coils 2a and 2b is effected by: (1) differentiating the levels of the excitation currents or (2) connecting via a switch a resister for modifying the attenuation time constant of one of the coils 2b. <IMAGE>
Patent GB-906644-A (GB)
IPC: F22B37/28
Abstract: 906,644. Separating liquids from gases. HAPPEL G.m.b.H., [trading as GEA LUFTKUHLER GES. HAPPEL G.m.b.H. & CO. KOMM.-GES.]. Jan. 26, 1959, No. 2827/59. Class 123 (3). In a smooth-flow device for separating liquids from supersaturated gases flowing at high speeds and pressures and comprising three transverse rows of equally-spaced baffles 2 which extend from top to bottom of an open-ended longitudinally-arranged housing 1, each baffle, formed from a sheet of corrosion-resistant metal, comprises a forward planar portion which is located in a plane inclined at an acute angle α to the direction of gas flow x and a rearward liquid-collecting pocket 3 which is constructed by bending the rear end of the sheet back upon itself, a narrow vertical slot 4 being provided between the rear edge of the planar portion and the folded back edge 3a of the metal sheet. The pockets 3 in each row of baffles 3 extend over a transverse cut-out portion 6 which is formed in a bottom wall 1a of the housing and has an inclined wall 6B extending downwardly from its front edge to direct liquid, falling from the pockets 3, to a corresponding collecting chamber 7 located beneath the wall 1a. Strips 8 arranged across the interior surfaces of the housing 1 prevent liquid from moving longitudinally along the housing walls. As shown in Fig. 2, adjacent rows of baffles have their planar portions inclined to one another. The angle of inclination α of the planar portions is chosen to vary inversely with the speed of the gas which also influences the number of rows of baffles to be employed. Various shapes of baffles are described, the baffle, Fig. 5, being provided, along its front edge, with a second planar portion 5 which is adapted to extend into a low-pressure area immediately behind the corresponding pocket 3 of a preceding row of baffles.
