Inventor: NEWMAN JACK HENRY
IPC: B65H75/12
Filed: 1959-10-30
Abstract: 894,817. Bobbins. BIRMINGHAM ALUMINIUM CASTING (1903) CO. Ltd. Oct. 26, 1960 [Oct. 30, 1959], No. 36850/59. Class 120(3) A bobbin or reel has a barrel drawn or spun as a shaped but smooth metal sleeve which is provided with a shaped former c at one end which forms a finger grip portion, the former c being provided with means h to prevent its rotation relative to the sleeve a and means i to prevent its rotation relative to a mandrel supporting the former c while the end part f of the sleeve a is spun or rolled on to it to shape the finger grip portion. To hold the former c in the aluminium sleeve a parts of the end part f are forced into radial recesses h, Fig. 4, provided in the former c. During the metal spinning operation a key on the mandrel engages a slot i in the former. A bore d forms the upper bearing of the bobbin. An identification disc may be inserted in a recess j. A disc b forms the bottom flange of the bobbin and is substantially as described in Specification 677,430.

Title: Steam turbine power plants with intermediate reheating between turbines
IPC: F01K7/22
Filed: 1954-12-21
Abstract: 774,225. Steam turbine plant. SULZER FRERES SOC. ANON. Dec. 21, 1954 [Dec. 23, 1953], No. 36863/54. Class 110 (3). [Also in Group XIII] A steam turbine power plant having a directly-heated intermediate reheater and an indirectly-heated regulatable intermediate reheater connected in series between two turbines has the side to which heat is supplied of the regulatable intermediate reheater connected between two superheaters of the steam generator and means for controlling the temperature of the reheated steam. Condensate from a condenser 1 is supplied by a pump 2 to a feed water tank 4 from which it is supplied by a feed pump 5 to a flue gas heated economizer 7, the vaporizing zone 8 of a steam generator and then through a pipe 9 into a first superheater 10. From the superheater 10 the steam flows through the primary side of an indirectly-heated regulatable intermediate reheater 12 into a second superheater 14 which is connected to a high-pressure turbine 16. The exhaust of the turbine 16 passes through the secondary side of the reheater 12 into a directly-heated intermediate reheater 18 and the low-pressure turbine 20. The heating effected in the reheater 12 can be controlled by taking water from the pipe 6 through a pipe 23 and injecting it into the pipe 9. The quantity of water injected is controlled by a valve 24 regulated by a device 25 influenced by temperature-sensitive elements 26 and 27 located in the pipes 9 and 19 respectively. The element 27 responsive to the reheated steam temperature forms the main control and the element 26 acts as a stabilizing control. A further temperature control, e.g. a second water injector pipe for injecting water into the pipe 13 may be provided to control the temperature of the steam entering the high-pressure turbine 16. The reheater 12 is preferably made of a low alloy ferritic steel and of welded construction. The reheater 18 may be made of austenitic steel and is preferably located in the steam generator where it is screened from flame radiation. In a modification, the reheated steam temperature is used to control a valve in a by-pass pipe in the primary or secondary sides of the reheater 12. The temperature-sensitive element 27 may be placed between the reheaters 12, 18. The turbine may consist of more than two turbines with more than one reheating stage, at least one of which comprises directly and indirectly heated reheaters arranged in series as described. The steam generator may be of any type and the invention is not restricted to the straight-through type shown.

Abstract: 435,668. Grates; ashpits. AMERICAN ENGINEERING CO., Aramingo Avenue, Philadelphia, U.S.A. Dec. 24, 1934, No. 36971. Convention date, Oct. 23. [Class 51 (i)] In an underfeed stoker furnace provided with alternately disposed retorts and rows of tuyÞre blocks, cooling tubes are arranged above the tuyÞre blocks to form a screen for chilling any molten ash flowing from the fuel bed above the tuyÞres. As shown in Fig. 1, cooling tubes 25 extend downwardly from a header 26 and over the tuyÞre blocks 4 and are connected to a lower header 28 both headers being in communication with the water circulating system of the boiler. In the modification shown in Fig. 2, the cooling tubes pass downwardly over fixed extension grates, arranged between movable extension grates 9, and are connected to a header 35 from which extend tubes 38 forming a shelf for ashes &c., connected to a lower header 39. In a further modification the tubes 25 are continued downwardly to the lower header 39 while intermediate tubes are disposed between the header 35 and the lower header 39. In the modification shown in Fig. 5, the tubes 25 are carried downwardly at 54 to form a wall of the ashpit 53 and are connected to a header 55. Intermediate tubes 56 are arranged between the extensions 54 and connected to headers 55 and 57. A pump 101 may be employed to assist circulation. The tubes 25 may terminate in vertical extensions with top and bottom headers or a bottom header only to form cooling means for any molten ash entering the ashpit. The tuyÞre blocks 4 may be provided with recesses 67, Fig. 12, to receive the cooling tubes and with cooling ribs 68. Fig. 11 shows a modification in which the cooling tubes 25 are spaced from the tuyÞre blocks 4.

Abstract: 985,998. Agitating thixotropic materials. THIKOL CHEMICAL CORPORATION. Oct. 16, 1961, No. 37032/61. Heading B1C. [Also in Division B8] In a method and apparatus for causing thixotropic material to flow from a container, the container 11 is vibrated by a table 12 and has internal fins 30 which work the material; an additional vibrator 48 is attached to the outlet pipe 45. As shown, the fins may be attached to the container at their outer ends, have their inner ends free, be radially arranged and have depending blades 31 twisted or secured at an oblique angle to the fin. The fin assembly may be made detachable by fixing the fins to a ring 64, 66 instead of to the container wall. A disc baffle 35 having an axially extending conical nose 38 is supported by legs 37 over the outlet 32. Interchangeable inverted cups 44 of different depths may be used to provide various ratios of the area between the legs 37 to that of the outlet 32 ; the preferred ratio is 1À25 to 1À00. An alternative form of baffle with which the ratio may be varied by adjusting the height of the baffle is described with reference to Fig. 5 (not shown). The outlet pipe 45 is flexible and provided with a pinch-cock 47. There is a jacket 26 for a heat exchange medium. A pressure-tight cover 28 has connections 50, 53 to compressed air and vacuum pumps 51, 54 respectively, the control valves 52, 55 being controlled by a single operating rod 56 so that the container 11 may be alternately pressurized to expel, and exhausted to de-aerate, the material therein. The table 12 is vibrated mechanically at the natural frequency of the springs 15 for the load imposed on them, the speed of the shaft 17 being suitably increased as discharge of material from the container 11 to the casting mould 14 decreases the load. The depending blades 31 act as paddles to propel the material about the outlet 32 and in combination with the internal shear forces set up by the fins and blades, and the arrangement of the baffle 35, maintain the surface level of the material substantially horizontal during discharge.

A warp or weft knitted pile fabric has the loops severed and the fabric treated such that the opposing pile of two such fabrics when placed together interengage to cause them to adhere to each other. The fabric may be composed of a warp knitted base having pile loops formed by the pile yarns extending around loop forming elements positioned adjacent the needles. The pile yarns are secured in the fabric together with the ground yarns forming the base fabric. The fabric is drawn off the machine whereafter it is subjected to heat or other treatment to set the pile loops which are subsequently severed. The pile loops may be severed in any convenient fashion but desirably are severed at the side to provide a hook portion which engages with a corresponding hook portion of an opposing fabric portion. The fabric treatment and loop severing operations may be performed whilst the fabric is on the knitting machine or it may occur subsequently after it has been removed. Alternatively the fabric may be produced on a Raschel machine having loop forming points in one bed. A fabric so produced can be utilized for hair curlers being wrapped round and secured to a cylindrical base.
