Title: Improved process for obtaining alcohol free from nitrogen bases
IPC: B01D3/00
Filed: 1936-08-24
Abstract: Alcohol free from nitrogen bases is produced from the distillation of fermented solutions by adding furfurol containing solutions during the distillation or rectification.  If the main solution contains 4 mgs. of nitrogen bases 20--25 mgs. of furfurol are added.  The first runnings from the distillation of fermented wood sugar solution contain sufficient furfurol to serve as the added solution. Alternatively a suitable furfurol-containing solution may be produced by heating the slop left in the distillation of fermented wood sugar solution.ALSO:Alcohol free from nitrogen bases is produced from the distillation of fermented solutions by adding furfurol containing solutions during the distillation or rectification.

Title: Improvements in and relating to the control of the rate of flow of fluids
IPC: G05D7/06
Filed: 1946-08-12
Abstract: 621,395. Automatic rate of fluid flow control systems. FROUDE, R. H. Aug. 12,1946, No. 23806. [Class 38 (iv)] [Also in Group XXXVII] The rate of flow of a fluid in a pipe is maintained constant by a valve actuated by a servomotor controlled by electrical contacts in the limbs of a mercury manometer which is connected across a differential pressure device located in the pipe. A venturi tube 10 fitted in the pipe 12 is connected with a mercury manometer 13 in which the mercury, connected to an electrical supply 14, forms, together with adjustable contacts 16, 17, a changeover switch (see Group XXXVII). A departure from the predetermined rate of fluid flow results in the mercury contacting one of the contacts 16, 17, thereby energizing one of the solenoids 45, 44, which operate a hydraulic changeover valve 38, Figs. 4 and 5 (not shown), to apply pressure to one end of the hydraulic piston and cylinder 35 actuating the control valve 11. Simultaneously, one of the solenoids 50, 51 is energized to tilt the mercury switch 49, Figs. 7 and 8 (not shown), and energize the solenoid 47 which opens locking valve 40, 41, Fig. 6, (not shown) in the lines supplying the piston and cylinder 35.

A button making device which produces a button at each operation comprises a first tool carrier having a charging position and a button forming position and a second tool carrier being movable relatively to the first tool carrier and having two tool carrying positions arranged so that when a tool in one carrying position co-operates with the tool in the button forming position another tool in the other carrying position co-operates with the tool in the charging position. The lower tool carrier 15 is mounted slidably on a shaft 11 and the upper tool carrier 20 is mounted to rotate with the shaft with a small axial movement, both carriers have two apertures for removable tool inserts 17, 21. A rod 24 extends through the shaft 11 and has a clamp 25 at the upper end and a connection with a double acting hydraulic ram 28 at the lower end. In operation, a button head and a piece of cloth are inserted in one lower tool insert 17, the hydraulic ram is operated and the upper tool carrier 20 rotates through 90 degrees by a pin 13 engaging in a cam track 12 on the shaft and thus descends the tool carriers 15, 20 descending together to a bed plate 14 where a mandrel 32 inserts the head and cloth into a tool insert of the upper tool carrier 20. The shaft 11 rises and rotates a further 90 degrees, a button back and button head and piece of cloth are inserted in the lower tool inserts. The shaft rotates through 90 degrees and descends, the back is attached to the button head and cloth in the upper tool insert producing a button and the button head and piece of cloth in the lower tool insert are inserted in the upper tool insert recommencing the operation. As a safety device the pin 13 which extends from a sleeve 41 rotates with the shaft 11 against the action of a spring 38 when there is some obstruction and operates a micro-switch 45 which breaks the drive to the rod 24.

Title: Process for reducing the residual content of vinyl chloride monomer in vinyl chloride polymers
IPC: C08F6/06
Filed: 1977-06-08
Abstract: Residual monomers are removed from homopolymers, copolymers or graft polymers containing at least 50% by weight of polymerised vinyl chloride. After removal of the majority of the unreacted monomers and, if present, the water, the polymer in the pulverulent state is subjected to heat treatment at from 75 to 120 DEG C for from 10 to 360 minutes at atmospheric pressure or under reduced pressure. The heat treatment is carried out in the presence of from 0.01 to 5% by weight, based on the polymer, of at least one aliphatic, saturated or unsaturated, branched or unbranched compound containing two free hydroxyl groups and from 2 to 24 carbon atoms and no heteroatoms connecting the carbon atoms, or containing two free hydroxyl groups, from 4 to 24 carbon atoms, at least one ether oxygen atom and, apart from the ether oxygen, no further heteroatoms connecting the carbon atoms. The use properties of the polymers are not impaired by the above treatment, in particular significant discolouration is not observed.
