Title: Improvements in or relating to tippable vessels
IPC: A47J27/14
Filed: 1961-05-05
Abstract: 939,743. Boiling pans. BURGER EISENWERKE A.G. May 5, 1961 [May 6, 1960; Oct. 5, 1960], No. 16381/61. Class 64 (1). The pivot 4 of a tippable, double-walled, steam heated boiling kettle 1 is placed in front of and approximately at a height half that of the kettle and comprises two separate rotatable pipes 5 and 6 used for the discharge of condensate from and the supply of steam to the jacket of the kettle respectively. The pipes rotate in aligned bearings 7, 8 and are connected through 90 degrees bends to pipes 5<SP>1</SP> and 6<SP>1</SP> which open at the bottom of the steam jacket, the other ends of the pipes 5 and 6 being connected via stuffing boxes 11 to fixed discharge and supply pipes 9 and 10 respectively. A lever 12 rigidly connected at one end to the pivot is further connected at its other end to the piston of a pivoted pneumatic or hydraulic assembly 13, the arrangement being such that the kettle may be tipped through an angle greater than 90 degrees. In the untipped position the kettle is closed by a hinged lid 15, rotation of the kettle causing its rear edge 18 to engage with a projecting surface 17 on the supporting arm 14 of the lid thus opening the same. The lid is kept open by means of a spring or counterweight and a similar system is used to move a filling pipe 19 out of alignment with the kettle on tipping. The kettle is mounted in a double-walled housing 20 having an apertured top surface with flanges over which flanges formed on the upper surface of the kettle fit when the latter is in the untipped position. A forwardly sloping, removable plate 23 having a collecting channel and outlet pipe 25 is provided in the lower part of the housing. The kettle may also be provided with an outlet pipe 31 which enables its contents to be removed without tipping. It is stated that the rate of tipping may be varied by controlling the amounts of oil or water supplied to the assembly 13. In Figs. 7 and 8 (not shown), a kitchen unit employing two such kettles and other cooking apparatus is shown.

Title: High pressure wellhead assembly
IPC: E21B33/037
Filed: 1962-04-30
Abstract: 948,044. Wells. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 30, 1962 [May 2, 1961], No. 16426/62. Heading E1F. A wellhead assembly connecting high pressure sources 15, 16 within a well to low pressure flowlines 32, 33 comprises short conduits 24, 25, landing surfaces for pressure-reducing chokes 47, 48 in the conduits, master valves 19, 20 at one end of the conduits, valves 30, 31 at the other end of the conduits, by-passes 54, 55 around the landing surfaces, valves 56, . . . 59 in the by-passes, and a cross-over connection 60 providing communication between the by-passes. The conduits are formed as branches on vertical passages 22, 23 which receive guide plugs 34, 35 having lower ends conforming to the inner surface of the conduits. Dual valves 18, 46 are included in the passages, and all the valves are hydraulically operated by fluid from pumps 76, 77, a valve being actuated by an electrical signal conducted by a cable 67 to operate one of the pilot valves 68-75. The assembly is mounted on a casinghead 14 of an underwater well and has a fluid-tight casing 66. The choke 47 is removed by opening valves 30, 56, 57, 58, 31 (the other valves being closed), by pumping a retrieving tool through the flowline 32 to latch on to the choke (the fluid pumped ahead of the tool being discharged through the flowline 33), and by pumping fluid through the flowline 33 to flush the tool and choke through the flowline 32. The tool and choke may also be removed by closing the valve 31, and opening the valves 20, 20a, 58 to allow well fluid from the source 16 to pass through choke 48, by-pass 55, connection 60, and by-pass 54 to the conduit 24 behind the choke 47. After the choke 47 has been removed a fresh choke or a well tool can be pumped to the conduit 24. When the well tool is pumped to a position above the valve 19a, the valves 30, 57, 58, 31 are open. The valves 30, 57 are closed, and the valves 19, 19a are opened to permit the well tool to fall into the well. The well tool may be returned to the conduit 24 above the valve 19a by opening the valves 19, 19a, 57, fluid from the well passing through connection 60 and open valve 59 to the choke 48 to discharge through the flowline 33. The well tool is removed from the conduit 24 by pumping fluid through the flowline 33 after closing the valves 19, 19a. Slugs of chemicals may be transmitted through the assembly in a manner similar to that of the well tool. In the construction shown in Fig. 2 the vertical passages are dispensed with and only the conduit 124 of the short conduits 124, 125 is curved for the passage of well tools although both conduits are suitable for the passage of chemicals. Specification 924,903 is referred to.

Abstract: 1,131,018. Tyre-building machines. AKRON STANDARD MOLD CO. 14 April, 1966, No. 16462/66. Heading B7C. In a tyre-building machine with two sets of stitching and ply-turning means, each including wheels 91, 93 freely and separately rotatable on an arm 98 rotatable on a polygonal shaft 102 journalled in a head 5 itself mounted for rotation about a vertical axis on a carriage 58 movable parallel and normal to the axis of the building drum 2, elastomeric torsion springs 110 are disposed between the shaft 102 and hub 100 therefor for yieldably maintaining a predetermined pressure of the wheel against the tyre components during rotation of the drum 2. The carriages 58 are movable axially of the drum on a carriage 3 movable normal thereto. The wheel 93 has a generally arcuate peripheral cross-section (see Fig. 9, not shown) for turning ply edges and is of smaller diameter than wheel 91, which has a cylindrical periphery, whereby the wheels may act independently on the tyre components. Switches are provided for maintaining a predetermined low or high pressure loading of the stitcher wheels on the drum. The control assembly includes manual control means operably connected to master potentiometers in circuit with respective reference potentiometers which actuate clutches for moving associated components.

Abstract: 774,176. Zips for furniture legs. HUSGEN, H. E., and DANIELS, R. R. J. Mar. 8, 1954 [June 15, 1953], No. 16464/53. Addition to 717,084. Class 134. A tube closure device, Fig. 2, comprises a mild steel stud 21 having spring legs 24 and 25. A mild steel cap 22 is secured to the stud 21 by two stakes 31. A plug 23 of rubber or like resilient material is forced into an aperture 29 in the cap 22. A hole 28 in the stud 21 allows air to escape when the plug is being forced into the cap. In an alternative embodiment, Fig. 10 a cover 36 is secured by means of stakes to a stud 32 of mild steel or other suitable rigid material. A mild steel cap 37 is secured by means of stakes to a metal liner 38. The two parts together with a rubber plug 39 are then placed in a mould under heat and pressure whereby the plug 39 is moulded around and bonded to both the cover and lined cap. The cover 36 and liner 38 are made of brass or other metal which will bond to rubber or rubber substitutes. Alternatively the metal to be bonded may be treated, e.g. by phosphorizing, so that it will bond to rubber. In a further embodiment a rubber plug is bonded to a stud and cover as shown in Fig. 10, and a steel cap is then spun on to an annular bead formed at the lower end of the plug.

Abstract: 475,779. Making flexible corrugated tubes. POWER FLEXIBLE TUBING CO., Ltd. June 16, 1937, No. 16744. Convention date, June 19, 1936. [Classes 83 (ii) and 83 (iv)] Corrugating.-Elastic flexible tubes or diaphragms, which may be used, for example, in thermostats in refrigerators, are formed by bending up a strip of readily weldable metal having a thickness of the order of 0À1 mm. to tubular form b, overlapping the edges b<1> and uniting them by electric resistance welding, and then forming corrugations in the tube. Annular corrugations e, e<1> are formed by rolling shallow grooves y, Fig. 3, in the tube b, further corrugations being formed in the intermediate cylindrical portions x by axial compression of the tube. Helical corrugations are formed by passing a tube b, Fig. 4, longitudinally through a rotated tool f having a part f<2> to complete the helical groove. Short lengths may be cut from tubes so formed and the ends shaped to form cylindrical attachment portions. Alternatively, the initial strip is of the length required for a single tube element. The material may be iron, rustless iron or steel, the alloy sold under the Registered Trade Mark " Monel," nickel-copper alloys, or German silver. A number of tubes may be nested before corrugating, a layer of iron, for example, being disposed between an inner and outer layer of the alloy "Monel."
