Patent GB-787383-A (GB)
Title: Process for producing superficial protective layers
IPC: C23C10/34
Filed: 1953-05-12
Abstract: A continuous, dense adherent surface layer of a regular desired thickness consisting entirely of a homogenous definite phase AmBn is formed on a metal A by free diffusion of a donor element B under conditions such that (a) the donor supplying the element B is on an average richer in atoms B than the phase AmBn, (b) the donor is in direct, intimate contact with the surface of the metal A, such contact being nowhere interrupted and (c) the progress of diffusion in equilibrium is ensured by the absence of any chemical, mechanical or thermal perturbation.  In modifications in which an unwanted layer of another phase forms on the outside (1) the unwanted layer is removed mechanically, chemically or electrically or (2) the diffusion treatment is continued in the absence of the donor, so that the unwanted layer itself becomes a donor.  The donor may be a powder of B or of an alloy a mixture of B with A or with an inert substance or may be a preformed coating deposited electrolytically, by chemical deposition, by vapour deposition or by sputtering: the metal A may itself be a coating.  If undesirable phases are liable to form below the layer of phase AmBn, a limited layer of A is superposed on a layer of an inert metal C and diffusion of B with A carried out until the layer A and the undesirable phases have been absorbed by the phase Am Bn.  In examples, Mo is heated in Si powder in a purified H2 atmosphere for 30 minutes at 1100-1300 DEG C.; Mo is treated in MoSi2 powder at 1500 DEG  for 1 hour: Mo is heated in Be or Al powder in H2 atmosphere at 1100 DEG C. for 1 hour: W, NC, Ta or alloys thereof are similarly treated; Mo or Fe is first coated with Cr and then heated with Si, Be or Al; Cr is itself so treated; Cu is heated in Be powder for 2 hours at 800 DEG C. in H2; Cu is treated with Al powder; Cu is heated in Zn powder for 20-30 minutes at 380 DEG C. in H2; Cu is heated in 80-20 Zu-Cu powder or in Cu Zn; Cu is coated with Sn, e.g. electrolytically, and heated at 450 DEG C. in a protecting atmosphere or at reduced pressure; Cu is heated with an alloy of 50-60 per cent Sn and 40-50 per cent Cn;: Ni is coated with Al and heated in a reducing atmosphere at 600-1200 DEG C.; Ni is chromized and a Crm Sin or Crm Ben layer formed thereon; Ni is molybdenized and a Mom Sin or Mom Ben layer formed thereon; Ni is coated with Su and heated at 450 DEG C. for 30 minutes.

Title: Improvements in and relating to servo motors for vehicle brake systems
Inventor: YARDLEY ALFRED
IPC: B60T13/569
Filed: 1965-03-30
Abstract: 1,144,567. Brake servomotors; valves. GIRLING Ltd. 29 March, 1966 [30 March, 1965], No. 13345/65. Headings F2F and F2V. A control valve, particularly for a brake servomotor in which reaction or " feel " is applied to the control valve directly by a diaphragm 27 through the action of a deformable deflecting plate 28 such as is described in Specification 1,144,566, may be either manually or hydraulically operated, and comprises a valve seat member 58 including a pair of relatively stationary valve seats 60, 62 respectively circumscribing one and both of two passages in the member 58, and a common valve closure member 84 which is fitted to the deflector plate 28 such that, on deformation of the plate 28, it tilts correspondingly so as to pivot about one of the valve seats and thereby open the passage circumscribed by the other valve seat. In order that the plate 28 should deform in the desired manner, a dished plate 94 is secured on the output rod 92 of the servomotor, which as shown is of the vacuum suspended type, and presents an annular bead 96 at a position radially inward of the centre of pressure of the diaphragm 27 so that when the valve is operated, as shown by movement of a pedaloperated rod 80 acting on a block 74 to push in a stem 50 which carries the head 58, the inner portion of the deflector plate, which is composed of flexibly joined segments, initially moves forward, causing deformation of the deflector plate 28 and hence pivoting of the closure member 84 about the seat 62 to open air passage 106, circumscribed by seat 60, allowing atmospheric air to pass via a filter 78 and passages 75, 102 to passages 104 arranged in a ring between the seats 60 and 62 and hence to the power chamber 24 of the servomotor, but, as pressure builds up in the chamber 24, the deformation of the deflector plate is progressively reduced until the lap position shown (in which it is flat), is reached, a reaction force then being exerted on the stem 50 which is proportioned in accordance with the relative radii of the bead 96 and the centre of pressure of the diaphragm 27. On relaxation of the force applied to move the stem 50 inwardly, deformation of the deflector plate 28 in the opposite direction occurs, causing the closure member 84 to pivot about the seat 60 and open the passages 104 via openings 42 left between the segments of the deflector plate to the vacuum chamber 22, thus restoring the vacuum suspended condition. When the brake is fully released a thickened portion 26 of the diaphragm rests on a reentrant portion of the servomotor casing. The casing is formed of two portions 12, 14 between which the outer periphery of the diaphragm 27 is clamped, the inner periphery of the diaphragm being engaged in a groove in the head 58. Return springs 95 and 98 are provided, and the arrangement is such that on failure of the vacuum supply the head 100 of an extension 88 of the output shaft 92 can be engaged directly by the thrust block 74.

Title: Improvements in diesel-electric and like power systems
IPC: H02P9/00
Filed: 1942-09-23
Abstract: 569,102. Transmitting mechanical power. BRITISH THOMSON -HOUSTON CO., Ltd. Sept. 23,1942, No. 13401.. Convention date, Sept. 25, 1941. [Class 38 (iv)] In order to increase the utilization of the power of a diesel-electric generating set comprising a self-excited generator 11, when furnishing its maximum current at low voltage to a self-propelled vehicle motor, an intermittent regulating relay 19 of solenoid type maintains the connection of a teaser battery 20 in the field circuit until the machine voltage has reached a predetermined value. This device is applied to a machine having a small degree of anti-compounding 14 which reduces the amount of stalling produced by the tendency of the load to exceed the engine power, the range over which the generator can utilize the full power of the engine being maintained by the invention. Further utilization of engine power, as the load voltage approaches its maximum, may be obtained by a non-linear resistance 45 with a negative resistance-current characteristic (Specification 292,110, [Class 38 (iv)], being referred to), shunted across part of a field circuit resistance 17. In a modification (Fig. 5, not shown), using a generator with the usual small cumulative compounding, a regulating relay having co-operating windings subject to field current and to armature current is adapted to maintain a short circuit on a portion of the field circuit resistance 17 up to voltage and current limits determined by the respective windings ; the teaser excitation is automatically removed by a separate electromagnetic switch when voltage and current conditions of the generator exceed predetermined values. The resistance 45 may be used in addition. The regulating relay 19 has a vibratory action and tends to keep constant the voltage or current or combination thereof to which it responds. Specification 299,054, [Class 38 (iv)], also is referred to.

Title: Improvements in and relating to foam-producing devices for fire extinguishing purposes
IPC: B01F5/04
Filed: 1939-05-05
Abstract: 528,369. Making foam. MULLER, J. May 5, 1939, No. 13453. Convention date, May 5, 1938. [Class 47 (ii)] In an apparatus for producing fire extinguishing foam a mixture of water and a foam producing substance is fed under pressure into a jet tube a through a tube b in the mouth of which is a conical distributing body l so that the mixture is ejected as an outwardly diverging jet which impinges on the walls of the jet tube a. A branch c in the tube b ending in a nozzle leads off some of the mixture to drive a turbine wheel g mounted on a shaft f between two partitions e. On the other side of the partitions the shaft f carries propeller wheels h the rotation of which sucks air in at the openings i and delivers it under pressure to the jet tube where it becomes entrained in the mixture impinging on the tube walls to produce foam which is projected by the air and mixture pressure from the jet tube. The position of the cone l is adjustable axially by the rod m and handle o and the amount of foam formed may be thus regulated. In another form the end of the tube b and the distributing body are so shaped that the ejected mixture divides into inwardly diverging streams which impinge on one another before being forced to the walls of the jet tubes.

Abstract: 882,317. Making turbines; welding by pressure. WIGGIN & CO. Ltd., HENRY. April 28, 1958 [April 26, 1957], No. 13471/57. Classes 83 (2) and 83 (4). In joining preformed parts of chromium containing alloy a very thin layer or layers of nickel is interposed between the parts, the parts are forced together and the assembly is heated in a non-oxidizing atmosphere to 1000- 1100‹ C. to diffuse the nickel substantially completely into the parts. The parts may have spigot and socket connection when one is forced into the other in a press and heated without maintenance of the applied pressure. If the parts have other shapes they may be held under an external pressure during the initial heating e.g. to 700‹ C. to promote initial diffusion and the pressure may then be released. The pressure may be obtained by interfitting after shrinking in dry ice. The nickel may be in foil, powder, sprayed or plated form. In embodiments the trapezoidal section root 2 of a gas turbine blade 1, Fig. 1, of nickel-chromium or nickel-chromium-cobalt alloy is covered with nickel foil 5 or is coated with nickel and is joined to the slot 3 machined in the rim of a rotor 4 of the same nickel-chromium or nickel-chromium-cobalt alloy. The sides of the slot which may be cut by spark erosion and the root sides may be parallel. A frusto-conical root 2, Fig. 2, of a turbine blade of 20% chomium, 20% cobalt, 2.4% titanium, 1.5% aluminium, 0.07% carbon, balance nickel is forced into a socket 3 in a rotor 4 of the same alloy with an intermediate layer of nickel 5 and the assembly heated in hydrogen to 1100‹ C. for 8 hours. The nickel foil covered or plated ends of a section of turbine blade 6, Fig. 4, with holes 7 formed by extruding a billet having inserts of filler metal, subsequently removed, are secured in sockets cut by spark erosion in root and shroud 8, 9. These parts may be assembled by shrinkage fitting. A number of sleeves are shrink fitted on turbine blade stock coated with nickel and joined thereto and the assembly is cut into blades with roots. Stainless-steel cutlery blades may be joined to stainless-steel shanks. According to the Provisional Specification if the surfaces to be joined are of superlative quality the interposed layer may be dispensed with-preliminary heating at 600‹ C. is then effected before pressing the parts together.
