Patent GB-120074-A (GB)
Title: Improvements in and relating to the Boxes and Switches of Electrical Fuses.
Inventor: DONOVAN WALTER
IPC: H01H21/06
Filed: 1917-10-18
Abstract: 120,074. Donovan, W., and Donovan, G. O. Oct. 18, 1917. Switch mechanism, interlocking with lids.-In switches of the kind in which the axis of movement of the operating-member is at right-angles to the hinge of the lid of the casing, and in which the switch cannot be closed when the casing is open, and the casing cannot be opened while the switch is closed, parts rigid with the operating- member interlock directly with parts rigid with the lid. When the lid is open, an arm h' on the back of the lid comes into the path of a projection g on the switch spindle and thus prevents closure of the switch when the lid is open. The operating-member c has a projection which co-operates with an arc-shaped projection on the front of the lid, thus preventing the opening of the lid when the switch is closed, and also the closing of the switch when the lid is nearly but not quite closed.

Title: Improvements in machines for scutching flax or like plant stalks
IPC: D01B1/20
Filed: 1938-05-21
Abstract: 514,221. Scutching flax &c. AUTOMATIC FLAX PRODUCTION UNITS. May 21, 1938, No. 15177. Convention date, Jan. 4. [Class 120 (i)] A method of scutching flax &c. in which a lap of stalks is subjected to the action of the radial scraping blades of two co-operating mills mounted side by side at the same horizontal level and rotating one in the other in opposite directions, is characterised in that the lap of stalks is scutched by one blade at a time, each blade terminating its action and releasing the lap as the following blade of the opposite mill commences its action and occupying at this time a position not below the horizontal. In a machine for carrying out the method, the flax &c. stalks carried by belts 10, 11 are treated by blades 8 bolted to plates 7 attached to arms 6 rotated by shafts 3. Each plate 7 is bent to provide a heel portion 12 carrying a blade 13 which operates to bring the stalks released by a "lower" scutching blade of one mill under an " upper blade of the opposite mill for more complete scraping. The plates 7 may be perforated at 15 so that air currents produced by the heels 12 may be directed by the aid of plates 14 to drive the stalks beneath the next scutching blade. In a modification the heel portion of each blade is separate from and adjustable with respect to the scutching blade.
Patent GB-797050-A (GB)
Title: Improvements in or relating to casting layers for the manufacture of films and sheets
IPC: B29C41/24
Filed: 1955-05-26
Abstract: In a film-casting machine, a casting support in the form of a rotatable drum or movable endless belt has a casting layer comprising an alginic acid fatty acid ester which, at least at the surface of the layer, has been converted into a metal salt of the ester which is insoluble in water and organic solvents.  The ester is a single or mixed ester of alginic acid wherein one or both of the hydroxyl groups of the anhydromannuronic acid group of alginic acid has been reacted with a fatty acid such as acetic, propionic or butyric acid. When the ester is converted into a metal salt by reacting it in solution with a salt of a metal, such as chromium, nickel or copper, which is capable of forming a soluble complex with a third compound present in the solution, such as ammonium hydroxide, the support may be coated with a solution containing a salt of the metal, the complex-forming compound and the ester, and then by appropriate treatment the complex may be decomposed with re-formation of the metal salt. This, in the presence of moisture, reacts with the ester to form an insoluble salt of the ester.  Alternatively, the support may first be coated with a layer of the ester and the coating then treated with an aqueous solution of an ionized salt of the metal. In this case the viscosity of the solution of the metal salt may be increased, and the speed of the reaction of the salt with the ester may be decreased, by dissolving in the solution a watersoluble film-forming substance such as gelatine, polyvinyl alcohol or a polyacrylic compound.  In a second alternative procedure a colloid layer may be applied to the ester layer and the metal salt solution then applied to the colloid layer so that the metal salt diffuses through the colloid layer to the ester layer.  In an example, 30 ml. of concentrated ammonia solution and 40 grm. of an acetic-butyric ester of alginic acid are added successively to 100 ml. of a 10 per cent solution of copper nitrate in a 50 : 50 mixture of acetone and water, and the resulting solution is spread on a metal plate.  After drying and washing the film-casting layer thus formed, a solution of cellulose triacetate in an 85 : 15 methylene chloride-ethanol mixture is spread on the casting layer and the solvent is evaporated.  The resulting film can easily be stripped from the casting layer.  In another example, a solution of an ester of alginic acid having 0.5 acetyl group and 1.2 propionyl groups per mannuronic acid group in an 80 : 20 acetone-water mixture is applied as a layer on the copper belt of a film casting machine and dried.  The surface of the casting layer is then uniformly moistened with a 1 per cent aqueous cobalt nitrate solution. After about one hour the resulting casting layer is ready for use.
