Abstract: 767,472. Drawing; extruding. DOW CHEMICAL CO. March 7, 1955 [April 22, 1954], No. 6678/55. Class 83 (4). Apparatus for correcting the profile of an extruded section of light metal or alloy, comprises a die 20 composed of a number of segments 40 made of an oily, flaky solid substance, which segments define an opening of the desired profile of the section. The segments 40 are made of soap stone, molybdenum disulphide, or preferably graphite or a mixture composed predominantly of graphite. These segments are adjustably mounted on a backing plate 34 carried by a support member 30. The segments may be water-cooled. The extruded section 22 issuing from the extrusion die 14, which is preferably made of an alloy of magnesium or aluminium, passes through the opening 32 defined by the segments 40 and is attached to a cable 26 running on a winch 28 or other means for maintaining the section 22 under tension as it passes through the correcting die 20. In another embodiment, Fig. 4 (not shown), the correcting die 20 is mounted on the run-out table of the press and may be withdrawn therewith to allow a cutting saw to swing into position to sever the extruded section. The correcting die 20 is preferably mounted so as to adjust itself to the general shaping of the section without bending or kinking it.

Title: Improvements in the manufacture of diketene
IPC: C07C45/88
Filed: 1951-03-21
Abstract: <PICT:0694899/IV (b)/1> In a process for the production of diketene, ketene is introduced into the working chamber of a gas pump within which a movable member is working in contact with diketene and the ketene is there polymerized to form diketene, while the pump is cooled to a temperature of from about 10 DEG  to about 70 DEG  C. Gas pumps which can be used include piston and plunger pumps, rotary pumps and rotary cylinder pumps.  Ketene gas may be prepared by pyrolysis of acetic acid in vacuo and cooled to free it from water and acetic acid. To complete the polymerization a column may be installed on the pressure side of the pump.  In the drawing ketene gas enters cooler 2 via pipe 1 the condensate being removed by means of valve 3.  The ketene gas is sucked through pipe 4 into chamber 6 of a gas pump, the casing 7 of which is surrounded by a cooling jacket 10.  The chamber 6 contains diketene as sealing liquid.  A cylindrical rotor with a sliding vane 9 is eccentrically positioned in the gas pump and rotates in the direction shown by the arrow. Diketene passes through a valve 11 into collecting tank 12 and thence to a column 14 provided with a cooler 13 from which it is continuously removed by a siphon 16.  Residual gas leaves the cooler 16 and is throttled by means of a throttle valve 17, the pressure being indicated by manometer 18.  Residual gas escaping through the throttle valve 17 mainly consists of carbon monoxide, carbon dioxide, ethylene and small quantities of non-reacted ketene.  The latter may be used for the production of acetic anhydride or diketene in second analogous apparatus.

Patent GB-829130-A (GB)
Title: Method of making a gear finishing tool
IPC: B23F21/03
Filed: 1957-03-06
Abstract: A gear finishing tool is made by forming a mould from a representation of a master gear, and moulding the tool in the mould thus formed.  A plastic model of a gear is formed, together with a model of a conjugate gear of a hard resilient plastic with abrasive particles embedded in the teeth, the models rolled in mesh to remove material from the plastic model as a result of the action of the abrasive particles, and a mould formed from the plastic model, in which is moulded a tool having teeth at least the surface portions of which are hard resilient plastic material in which abrasive particles are embedded.  The models are rolled in mesh preferably by driving one of them first in one direction and then in the other and opposing rotation of the driven member, e.g. by brake action.  The invention is particularly useful in the finishing of bevel, spiral bevel, or hypoid gears having crowned teeth.  In such a case initial contact between the teeth of the plastic gear and the plastic abrasive tool is limited to a zone central of the teeth but as the two are rotated in mesh the teeth of the plastic gear become longitudinally concave and capable of contacting the teeth of the abrasive tool from end to end.  The final gear finishing tool is a counterpart of this modified plastic model gear and accordingly its teeth are longitudinally concave by an amount sufficient to cause them to engage substantially uniformly from end to end with the crowned teeth of a metal pinion and to finish the teeth of this pinion from end to end.  The tool may be formed in its entirety of the hard resilient plastic material or may have a disc-shaped metal core and plastic teeth.  The metal disc may have short teeth which extend partly into the plastic teeth. Suitable plastic materials are epoxy casting resins in which 60 grit abrasive such as silicon carbide is incorporated.  The moulds may also be made of epoxy resins but it is preferable to use a material of higher heat resistance, e.g. phenolic resins such as phenol formaldehyde and phenol-furfural compounds or polychlorotrifluoroethylene, so that the epoxy resin may be heated during moulding.  Specification 800,680 is referred to.
