Title: Process for the manufacture of composite metal-ceramic material
Inventor: WELLARD ROGER JACQUES
IPC: C22C32/00
Filed: 1952-11-07
Abstract: <PICT:0723842/III/1> <PICT:0723842/III/2> A process for manufacturing refractory and mechanically strong composite material of the type having metallic and ceramic constituents other than siliceous substances in close adhesive relationship for gas turbine blades or other heat engine elements comprises heating separately said constituents to a temperature at which they are in a softened condition and simultaneously and separately spraying said constituents on to a support whereby said metallic and ceramic constituents closely mix on the surface of said support.  Apparatus for carrying out the invention comprises an oxyacetylene blow pipe 1 into which metal is fed in the form of a filament 4 so that the jet issuing from the nozzle 5 of the gun carries grains of molten metal which are projected on to a support 6 heated by a furnace 11. Another similar gun 7 is fed with a powdered ceramic constituent from a hopper 9 and this also is projected on to the support 6.  On cooling, the composite material is separated from the support.  The guns may be operated simultaneously to deposit a mixture of metal and ceramic grains on the support or they may be operated alternately to form fused laminated layers of metal and ceramic on the support.  The metal projected from the gun 1 may be steel or an alloy containing nickel, chromium, cobalt.  The ceramic constituent is a mixture containing a high proportion of refractory grains, e.g. an oxide, a carbide, a boride, a nitride or a mixture of these substances and a binder which may comprise vitrifying agents e.g. agents having a base of borax or of lithium oxide.  In a modification a number of fixed guns are used to deposit metal and ceramic constituents alternately on a travelling or reciprocating support resting on rollers 12.  The support may be a mould of metal or refractory material from which the composite material is withdrawn.  In a further modification of the invention in order to increase the porosity of the material, one of the constituents is partially replaced by a third constituent which may be an organic or organo-metallic material or a mineral salt which is volatile or soluble or decomposable by heat, e.g. plastic materials.
Patent GB-1309798-A (GB)
Title: Devices for connecting two submerged enclosures
IPC: E21B41/06
Filed: 1970-06-10
Abstract: 1309798 Ships fittings COMPAGNIE FRANCAISE DES PETROLES SA 10 June 1970 [11 June 1969] 28155/70 Heading B7S [Also in Divisions E1 and F2] Three concentric annular blades 6, 5, 14 are arranged to form a seal between a tubular access member 3 (attached to a movable subaqueous enclosure) and a fixed subaqueous enclosure. The wall 1 of the fixed enclosure has a circular access opening 2 aligned with the access member 3. As shown the blades 6, 5 are secured via a ring 4 to the access member 3, and an inflatable seal 7 is housed between the blades. The outer blade 14, bearing a lip seal 20, is connected to the intermediate blade 5 by a rolling diaphragm 13, a chamber 35 being defined thereby. A wall 23 secured to blade 14 coacts with a spherical surface 15a on an abutment 15 carried by blade 15, the wall also loosely pivoting a plurality of jacks 28 (e.g. 3 jacks). The upper ends of the jacks are secured to the enclosure to which access member 3 is attached, preferably at least one jack is rigidly secured and the remainder are pivotably secured so that the blade 14 may take up a slightly misaligned position with respect to the other two blades. A ring 29 coacts with abutment 15 to prevent mislocation of blade 14 when not connected to a fixed enclosure wall 1 Operation.-(The operation is similar to the method described in U.K. Specification 1,287,905). The jacks are pressurized by a constant pressure reservoir so that blade 14 extends axially beyond blades 5 and 6. The two enclosures are brought together so that the edge of blade 14 bears on the inconstations surrounding aperture 2 and some of the water in the access member 3 is pumped into the movable enclosure to create a slight underpressure in chamber 34 sufficient to over come the force of the jacks so that blades 5 and 6 are gently brought into contact with the surface of the inconstations while blade 14 breaks through to the surface of wall 1. The lip seal 20 prevents ingress of water so that chamber 35 may be emptied until the blades 5 and 6 are in contact. The pump is then stopped and the access member is brought into communication with the movable enclosure via a valve of large cross-section. As the movable enclosure is internally at atmospheric pressure the pressure within the chamber 34 quickly falls to this value and the blades 5 and 6 are forced by the hydrostatic pressure to break through the inconstations to the wall 1. Immediately afterwards the seal 7 is inflated after which the remaining water is pumped from chamber 34. Should any leakage still occur the inconstations may be manually removed from the surface 12 and a further inflatable seal 32 inserted in a recess 6a. The further seal may be retained by a segmented ring 33.

Abstract: 1,139,901. Stop motion. JAMES MACKIE & SONS. Ltd. 22 June, 1966 [2 July, 1965], No. 28161/65. Heading DID. A stop motion, used on a spinning frame for the wet spinning of flax from a rove which is drawn through a water trough, comprises a detector 20 bearing against the yarn and controlling a balanced assembly 21, 32 in such a way that breakage of the yarn and resultant movement of the detector upsets the balance and reduces the distance between a magnet 24 and a plate 23 to a value sufficiently small for these two to move together and clamp the rove. Magnet 24 can be a permanent magnet. The detector can form an extention of lever arm 21 which pivots about fulcrum 22 can carry a fixed counterweight 25 and an adjustable weight 28. The stop motion can be held in its balanced position by cam 30 when the frame is not operating. The yarn passes through feed rollers 11, 12, under rod 13 in the water trough, through drafting head 4, past lappet 15 and is wound onto spindle 7 by ring and traveller 6.

Abstract: 766,007. Travelling-wave tubes. STANDARD TELEPHONES & CABLES, Ltd. Oct. 14, 1953, No. 28270/53. Class 39(1). A travelling-wave tube comprises a helix 6, Fig. 1, carried within and by a tube of insulating material 7 which is supported at at each end on sleeves 8, 9 at least one of which is an inner choke sleeve member, the sleeve member 8 at the gun end of the tube being mounted on or forming part of the gun. In Fig. 1, wire helix 6 is carried by tube 7 of insulating material mounted at either end on sleeve members 8, 9, the outer portions 17 of which form the inner portions of waveguide chokes. Lorry material is pointed or evaporated on the inside or outside of tube 7, and impedence matching pistons 14 are provided. The ends of the helix 6 are connected via wire frobes 20 to bosses 18, 19 of sleeve members 8, 9. Sleeve member 8 is carried by a metal tube 21 secured to gun anode 22 or to insulating washer 26. The cathode 23, focussing cylinder 24 and anode 22 are supported by rods 25 and insulating washers one of which is 26. The collector 4 has a locating step 29 for insulating tube 30 supporting sleeve 9 so that in manufacture the gun, helix and sleeve assembly can be inserted as a unit into the envelope until tube 30 seats on step 29. The beam is focussed by an assembly of coils (not shown). In another embodiment, Fig. 2, the gun is surrounded by pole piece 35 which supports the anode from its front surface and also serves as an inner waveguide choke member, and sleeve 41 similarly serves as a second pole piece and choke member. Members 35, 41 carry the helix support tube 42 by means of bosses 43, 44. The ends of the helix are brought out from tube 42 through slots 46 and connected to U-shaped probes 47 which are as described in Specification 755,834. Three ceramic rods 48 have sleeves at their ends having flanges 49 which are welded to members 35, 41 to form a rigid assembly. Collector 38 has cooling fins 39 and a metal evacuating tube 40 which also provides the locating surface and support for the unitary gun-helix electrode assembly. 52, 54 are outer pole piece members of copper plated ferromagnetic material and also serve as outer choke members. 54 is - #/4 long and 52 has a portion of relatively small bore long and a further portion 53 of larger bore. The portion 53 together with the gun form an open circuited line of comparatively high impedance so that little energy escapes. The pole piece member 52 may butt against the guide wall, as shown, or the guide wall can be cut away so that the end surface of 52 is flush with the inner surface of the guide. Additional chokes 55, 57, 56, 58, and pairs of short circuiting rods 61, 62 cooperating with, matching guide sections 59, 60 are provided. The tube may be used as an amplifier, oscillator or frequency changer. Specification 762,106 also is referred to.
