Patent GB-1130927-A (GB)
Title: Improvements in the operation of electrical moving coil relays
Inventor: HILL ANTHONY
IPC: H03K17/965
Filed: 1965-09-13
Abstract: 1,130,927. Switching arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 12 Sept., 1965 [13 Sept., 1964], No. 38942/65. Heading H2H. The response of a moving coil relay 6 to a D.C. signal of the polarity shown is modified by the resistors 2, 4 and Zener diodes D1, D2 whose effect is to produce no response to small input signals and an accelerated rate of response to larger input signals. The relay coil is so connected that current through it via the resistors is in the direction for which deflection of the coil is prevented, so that unless the input current is sufficiently high for the potential drop across each resistor to exceed the striking potential of the diodes, there is no coil deflection. For input currents exceeding this value, the coil current is the difference between the (constant) current through the resistors and the current through the diodes. This will exceed zero at a determinate threshold current, and for input currents higher than this threshold value deflection results. It is shown with reference to performance characteristic diagrams (Figs. 2 to 4, not shown) that the response of the coil to input currents above this threshold is much more rapid than it would be if such a current were connected directly to the coil alone.

Abstract: 809,879. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. Dec. 27, 1956 [Dec. 27, 1955], No. 39264/56. Drawings to Specification. Class 56. A glass sheet is lowered. in a vertical plane into a liquid bath (e.g. of molten aluminiumsilicon alloy) kept at a high temperature. When the sheet is sufficiently soft it is bent to the desired shape by means of co-acting solid mould members that are carried in the bath.

The anode in an electrolytic capacitor is formed of metal filaments having a generally round cross-section, each having a major crosssectional dimension of 0À5 mil. or under. The filaments may be relatively long, as shown, i.e. of the order of the length of the anode slug, or short (Fig. 4, not shown), and bonded together e.g. by sintering. They may be twisted into a yarn (Fig. 5, not shown) which may be formed into a helix (Fig. 6, not shown) or a double helix (Fig. 7, not shown). Single filaments may be arranged in side-to-side parallel relationship (Fig. 8, not shown), or the twisted yarns may be so arranged. When the filaments are formed into a ribbon a wound capacitor (Fig. 10, not shown) may be formed. The anodes may be used in wet electrolytic capacitors, e.g. having a spacer impregnated with sulphuric acid, or dry, having pyrolytically formed manganese dioxide as the electrolyte. For a non-polar capacitor the counter-electrode may be similarly constructed and anodized.

Abstract: 976,449. Controlling aircraft. GENERAL ELECTRIC CO. Oct. 16, 1963 [Oct. 18, 1962], No. 40845/63. Heading B7G. An aircraft is provided with a gas generator having a duct 13 (Fig. 1) carrying exhaust gases to at least one outlet to produce thrust, each outlet 15, 16 being provided with a cascade of louvres movable relative to the outlet, each cascade including two sections of differently directed louvres. The cascades 17, 24 may be translatable (Fig. 3) or rotatable (Fig. 6) across the outlets and are arranged so that one section of louvres provides forward thrust and one section provides reverse thrust. Movement of the cascades over the outlets thereby produces variations in the relative amounts of forward and reverse thrust. The portions of the cascades between the sections may be openable to increase the nozzle area and reduce the loads on the gas generator. In a modification (Fig. 4), the translatable cascades have sections in different planes, so that the exhaust can flow directly forwardly or rearwardly. In another modification (Fig. 7, not shown), the cascades are moved in planes inclined to each other so that direct rearward flow is possible. One section of each cascade has horizontal louvres to provide direct lift or for pitch control. The gas generator and outlets may be located in the fuselage or in nacelles.

Title: Improvements in or relating to the manufacture of non-woven fabrics
Inventor: FAIRFULL ANDREW EVAN SPOWART
IPC: D04H1/645
Filed: 1962-10-30
Abstract: A bonded fibrous fabric is prepared by the steps of impregnating a web of carded or randomly oriented fibres with a dispersion of an elastomeric material which may be coagulated by cooling, cooling the impregnated web and subsequently drying the web.  The cooling process is preferably carried out sufficiently rapidly to freeze the dispersion and to form numerous small ice crystals about which the coagulated material is deposited in reticulate form.  The dispersion may be applied to the web by spraying, dipping or in the form of a foam and may include curing agents for the elastomeric material and/or a destabilizer for the dispersion.  Cooling may be effected by passing the impregnated web through a refrigerated chamber, over a chilled roller or preferably by drawing cold air through the web. Subsequent drying of the treated web may be effected by freeze drying, heating by means of an oven or by passage of hot air through the web or by radio frequency heating.  Further heating may be required to effect curing of the elastomeric binder.  Fibres which may be used include polyamide, polyester, acrylic, cellulosic and cellulose acetate fibres and mixtures thereof.  Suitable elastomeric materials include dispersions of butadiene/acrylonitrile copolymers, polyisochloroprene, styrene/butadiene copolymers, polyacrylic esters, butadiene/methacrylate copolymers, polyacrylate resins, styrene/acrylate copolymers, natural rubber and internally plasticised polyvinylchloride.  Destabilizers referred to include ammonium chloride and zinc ammonium nitrate.

Abstract: 1532226 Welding by pressure CLARKE CHAPMAN Ltd 8 Oct 1976 [10 Oct 1975 5 May 1976] 41536/75 and 18310/76 Addition to 1303968 [Heading B3R] In an improvement in the invention claimed in parent Specification, the reaction load between the workpiece supports 28, 40 during compression is borne by tie bars 10, which in use are in tension and prevent any bending load on the body structure of the friction welding machine adversely affecting the alignment of the workpieces by bending of sliding surface 64 along which the movable workpiece support (e.g. 40) runs. In an embodiment, the machine comprises two beam elements (e.g. levers 14, 16) which at their lower ends are pivotally connected to the body structure 12, have the tie bars 10 pivotally connected at 30, 32 intermediate their ends, and at their upper ends have an hydraulic ram 22 for moving along the surface 64, a sliding head 42 carrying one of the workpiece supports (e.g. a chuck 40) and a stationary workpiece support 28 pivotally connected at 20, 26. In operation workpieces are held in the chuck 40 and a clamp 44 and supported by respective backstops (250, not shown), and 28. The chuck 40 is rotated by a motor 50 and advanced by the hydraulic ram 22. When the workpieces are forced together the reaction on the ram 22 tends to pivot the lever 14 anticlockwise, so putting the tie bars in tension which in turn pivots the lever 16 anti clockwise. This forces the backstop 28 against the workpiece associated therewith. The tension in the tie bars 10 prevents distortion of the sliding surfaces 64. The position of the backstop 28 relative to the clamp may be adjusted by virtue of keyways 74. The pivoted connectors 24, 30, 32 and 26 are part spherical. In further embodiments both the levers may be housed in the body structure 12 (Fig. 8, not shown), one of the levers 16 may be replaced by twin yokes (Figs. 9, 10, not shown), the motor driven clutch may be part of the stationary support, there may be two motor driven chucks on sliding head with a stationary clamp for a third workpiece disposed between.
