Patent GB-578086-A (GB)
Title: Manufacture of butadiene
IPC: C07C2/76
Filed: 1943-04-30
Abstract: Butadiene is made by heating ethylene in the absence of iron or nickel to a temperature of 750-900 DEG  C. for not more than 2 secs. and rapidly cooling the resultant gases.  Steam may be present. Ethylene, alone or with steam, may be passed through a heated tube of iron-free silica or of alundum glazed internally with sodium silicate.  The tube may be pretreated with sodium dichromate in sulphuric acid.  It may be heated electrically or the ethylene mixed with superheated steam, and may be empty or packed with inert material such as granulated silica or copper wire. Continuous operation may be effected by periodic replacement of ethylene by air to burn off carbon.  The gaseous products may be liquefied and fractionated to separate a butadiene-rich fraction. In examples: (1) a 1/2 " diameter silica tube is heated to a mean temperature of 800 DEG  C. over its central portion and oxygen-free ethylene passed with a contact time of 1 sec.  The exit gases contain 6 per cent butadiene and 70 per cent ethylene by volume; (2) ethylene is passed through an alundum tube glazed with sodium silicate under the same conditions but in a cyclic manner with alternating passage of air.

Title: Improvements in or relating to the manufacture of flexible films
Inventor: PHILLIPS CYRIL HOWARD
IPC: C08J7/052
Filed: 1961-02-24
Abstract: A solid particulate material is applied uniformly to at least one side of a coated or laminated film having variations in thickness across its width, in an amount of 0,001S to 0,025S g./sq.m. of film, where S is the specific gravity of the material, the average particle size of the material being within the range 5-45 microns. Preferably, the amount of material applied is within the range 0,002S-0,020S g./sq.m., and desirably the amount applied is 0,005S-0,020S g./sq.m. for particles of average size 5 microns, 0,003S-0,015S for particles of average size 15 microns, and 0,002S-0,010S g./sq.m. for particles of average size 45 microns. Specified solid particulate materials include starch, starch esters, resin coated starch, diatomaceous earth, silica, talc and powdered polymers and copolymers, e.g. polyvinyl chloride, vinylidene chloride/acrylonitrile copolymers and vinylidene chloride/methyl methacrylate copolymers.  The film may be of cellulose, polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate, a polaymide or a vinylidene chloride copolymer, and may be a laminate of like or dissimilar materials, or may be a base film of one of these materials coated with a coating composition. The coating composition may be applied to the film as a solution in a volatile solvent or from an aqueous dispersion and the particulate material may be applied to the coated film before the coating is dried.  Where the coating composition is a polymeric material which is applied to the film in a molten state, the particulate material may be applied to the films before the coating solidifies.  Coating compositions specified include heat-sealable and moisture proof coatings, e.g. nitrocellulose/wax compositions, and polymeric products, e.g. polyethylene and vinylidene chloride polymers.  Films so treated can be wound into a roll substantially free from hard circumferential bands.  Specification 961,989 is referred to.

Filed: 1924-03-20
Abstract: 224,794. Maschinenfabrik Oerlikon, (Assignees cf Laternser, A.). Dec. 14, 1923, [Convention date]. Controllers, actuating; master control systems.-For electric traction motors, a rheostatic starting controller operated in steps by a pilot motor is arranged so as to progress automaticallv, non-automatically or semiautomatically as required. The arrangement consists essentially of a master control switch FS, a group SW of self-controlling segments and contact fingers upon the main controller (the power contacts of which are not shown in the diagram), and a notching relay SR having three windings. According to the setting of the master controller FS and of a switch S, the notching relay is subject only to overload m a main current coil MC, or only to successive impulses of control current in a coil K<1>, or to the overload and control current impulses jointly. The object of the third coil K<2> is to neutralize the main current coil WC when purely non-automatic action is required. The notching relay checks the progression by de-energizing a magnet KR which makes a braking. short-circuit for the pilot motor A and at the same time applies a mechanical detent to a notched disc AS. The pilot motor is arranged to reverse either when the master controller is set back, or when safety relays come into action.
