Title: Improvements in and relating to metallic coating of metal articles such as valves and valve seats
IPC: B23K31/02
Filed: 1945-09-24
Abstract: 635,891. Coating with metals. TRIGGS, W. W. (Merco Nordstrom Valve Co.). Sept. 24, 1945, No. 24740. [Class 82(ii)] [Also in Group XXIX] In a process of providing an article such as the seating surface of a valve, or a valve seat of a metal having a low critical temperature range in which a reversal from contraction to expansion takes place on cooling, with a facing resistant to erosion and galling, the article is first coated with a molten ductile metal, followed by coating with a harder metal in molten state whilst the temperature of the article is substantially above the said critical temperature range. The invention is described in connection with coating the surfaces of a valve body and valve plug which may be of medium carbon steel, 4-6 per cent chrome steel, or-for use at high temperatures of 1,000‹F or more-of 4-4-6 per cent chrome steel consisting of 4 to 6 per cent chromium substantially 0.5 per cent molybdenum and the balance iron. The ductile metal may be nickel, stainless steel such as 18-8 chrome-nickel steel, 27 per cent. chrome steel, a nickel-molybdenumiron alloy such as " Hastelloy B " (Registered Trade Mark), brass, "Monel" metal (Registered Trade Mark), or silver, and may be applied by arc welding or by an oxyacetylene flame in a reducing atmosphere. The harder facing metal is preferably a cobalt-chromium-tungsten alloy such as " Stellite " (Registered Trade Mark) or a nickel-chromium-boron alloy such as "Colmonoy," and is flowed on to the ductile metal layer by means of an oxyacetylene torch having a neutral flame while the valve, &c., is in a reducing atmosphere in a furnace in which the valve, &c., has been pre-heated above the said critical temperature range and preferably to 1,350‹F. The ductile metal layer is preferably thicker than the facing layer. In the tapered plug valve shown, after preliminary machining of the valve body to provide bearing seats 16, 17, and of the plug 18, the seat is machined to provide recesses 55 and the plug diameter is reduced. The recesses are then filled with the ductile metal layer 59 followed by the harder metal layer 61, the plug similarly being coated with corresponding layers 63, 64. The valve throats may also be similarly coated (Fig. 5 not shown).

Title: Improvements in prism lens systems
IPC: G02B13/10
Filed: 1955-08-30
Abstract: 823,129. Optical systems. KODAK Ltd. Aug. 30, 1955 [Aug. 30, 1954], No. 24803/55. Class 97(1) A non-anamorphotic optical system comprises two anamorphotic prismatic systems crossed at right-angles, each system being formed of two refracting prism doublets each rotatable about an axis parallel to its refracting edge, all the prism doublet being rotationally interconnected such that in any position the magnification given by the two prismatic systems is the same and the range of rotational operation giving a magnification from M to 1/M when M is greater than unity. The system shown in plan in Fig. 19 and in elevation in Fig. 20 comprises two compound prisms 191, 192 with their effective refracting edges parallel and arranged on opposite sdes of the optical axis of an objective 57, and two similar compound prisms 193, 194 similarly arranged but with their refracting edges perpendicular to those of the front pair. Thus the prims 191, 192 produce a magnification or reduction in a vertical plane and the prisms 193, 194 a magnification or reduction in a horizontal plane. To vary the magnification each prism is rotatable about an axis parallel to its refracting edge, the pairs of axes being interconnected for simultaneous rotation in opposite directions by gears 231, 232 and 233 and 234 respectively, driven by worms 241, 242 on a rotatable shaft 240. To permit rapid selection of a number of predetermined positions the shaft 240 may slide axially in a bearing 243 being held in the said positions of engagement of a spring- pressed ball with notches 244 in the shaft 240. The system forms an image in plane 58 and to ensure that only collimated light falls on the prisms a lens system consisting of a fixed pane convex lens and a planoconcave lens axially movable for focussing may be provided the two  curved surfaces having the same radius of curvature and, when in contact, having their centre of curvature near the entrance pupil of the parts of the system following the lenses. Alternatively rotatoion of the prisms may be effected by a sliding rack engaging the gears 231 and 233, In a modification the prisms may be fixed within a casing the change of magnification being effected by reversing the casing before the objective 57, two such systems being used one behind the other to increase the range of magnification. The prism system may be used to give variable magnification in a telescope, being placed in a position where the light is collimated such as between the lenses of an eyepiece. The system may also be used as a direct vision magnifier the object to be viewed being placed in the plane 58. Specifications 823,130 and 823,131 are referred to.

Title: Improvements in or relating to yarn or like winding machines
IPC: B65H54/32
Filed: 1939-08-29
Abstract: 535,416. Winding yarns &c. NASMITH, F. (Universal Winding Co.). Aug. 29, 1939, No. 24831. [Class 120 (ii)] In a yam or like winding machine having a rotating winding spindle, a thread guide and means for causing relative longitudinal reciprocation between thread guide and winding spindle, means are provided for progressively reducing the length of the traverse during winding so as to form a package having both of its ends tapered, the degree of taper at one end being varied by an adjustment of the parts without substantially varying the degree of taper at the other end of the package. As shown, the thread guide 28 is carried by a traverse bar 27 reciprocated longitudinally of the winding spindle 21 in a swinging frame 23: The guide is pivoted on a pin 39 in a member 37 which is pivoted by a pin 36 to a carrier 34 having a lower bent end engaging a slot in the bar 27 and an upper hooked end engaging the plate 33 between the lower end of which and a recessed member 26 on the frame 23, the traverse rod slides. A spring 40 interposed between arms 41, 43 on the guide 28 and the member 37 respectively forces the thread guide against a wire bail 59 which bears against the package being wound and a pin 42 on the arm 43 engages a slot 45 in a trackway 44 pivoted by a screw 52 to the plate 33 and having a follower 47 engaging a cam slot 48 in a plate 49 adjustably secured to the stationary frame 20 to vary the lengths of the traverse. As winding proceeds the follower 47 rides along the slot 48 and swings the trackway 44 about its pivot 52 so as to rock the thread guide laterally and cause the traverse to be progressively shortened and a package with tapered ends formed. The trackway and the plate 33 are formed with a series of pivot holes 54, 55 and by removing the screw 52 from one pair of holes to another, the taper at the nose end of the package may be varied without substantially altering the taper of the base end because the rate of linear displacement of the end of the slot 45 nearer the follower 47 is not altered materially. The degree of taper at the nose end may be adjusted by altering the inclination of the cam slot 48 and/or by varying the length of the traverse stroke or adjusting its limits longitudinally of the trackway. The wire bail 59 distributes the pressure of the swinging traverse frame 23 along the whole length of the package and forms a track for the yarn so that the wear is distributed along the slot of the thread guide ; the bail is carried by a bar 58 secured to a pin 57 pivoted in spaced lugs 56 at the back of the plate 33, an adjustable plate spring bearing against the pin and permitting angular adjustment of the bail. A curved yarn rest 64 is secured to a pair of bosses at the rear of the plate 33. Specification 448,940 is referred to.

Title: Improvements in or relating to heat treatment of canned evaporated milk
IPC: A23C3/023
Filed: 1946-08-21
Abstract: 638,663. Sterilizing canned evaporated milk. FOOD MACHINERY CORPORATION. Aug. 21, 1946, No. 24903. Convention date, Sept. 4, 1945. [Class 49] [Also in Group XXX] In the heat treatment of canned evaporated milk whereby the cans are introduced into a gaseous heating medium containing steam at a temperature enough higher than that of the milk to cause deposition of milk solids on the inside surface of the can if the heating medium were steam alone, such deposition is prevented by admixing with the steam a non-condensable gas, i.e., a substance which is gaseous at a pressure of 760 mm. of mercury and 0‹C, e.g., air. Uniformity of the steam-gas mixture may be maintained by withdrawing the mixture from the treating zone and returning it thereinto. Any condensate is removed sufficiently rapidly to prevent submergence of the cans. For cans of milk of 12-25 per cent non-fat solids and a heating medium of temperature above 212‹F the per cent partial, absolute pressure of non-condensable gas is calculated from the experimentallyderived formula: Y-20=log 10 -1[0.7782 + 0.0266(X-2.55S+ 47.3)] + log 1  0 -1 [3.0000 + 0.106(X-2.55S + 47.3)] Y being the difference in ‹F between the temperature of the heating medium and that of the milk when introduced into the heating medium, X the per cent partial absolute pressure of non-condensable gas in the heating medium, and S the percentage by weight of non-fat solids of the milk. With the apparatus of Figs. 4, 7 and 12, cans at 50‹F are led by an inlet valve assembly 10 into a pressure chamber B, are advanced along a helical runway on the inside wall of the chamber, and there heated by a steam-air mixture, leaving the chamber, by an cutlet valve assembly 50, at 225‹F. The steam for heating is delivered by a pipe 90 through a pipe 100, on which is a regulating valve 105, through a series of pipes 95 into the chamber B. Compressed air is supplied through a pipe 135, on which is a regulating valve 145 responsive to the pressure within the chamber B, through a pipe 137, and through a series of branch pipes 140 into elbows 116 on conduits 115, the air entering the chamber by way of injectors 118. Uniformity of the steam-air mixture in the chamber B is promoted by supplying steam through a pipe 126, in which is a self-acting pressure responsive valve 130, through distributor pipes 123 and through nozzles 122 in the injectors 118, thus expelling the steam-air mixture from the chamber by way of the elbows 116 into the conduits 115 and back into the chamber.
