Title: Improvements in and relating to the dyeing of textile materials
Inventor: FRANCE EDWARD
IPC: D06P1/34
Filed: 1956-05-31
Abstract: Textile materials of cellulose triacetate are dyed with a logwood colouring matter by applying the colouring matter from a dyebath containing a swelling agent for the textile and then developing the colour by treatment with an aqueous solution of a laking agent, such as a dichromate, in the absence of a swelling agent.  Specified swelling agents, which may be employed in admixture, are ethyl, n-propyl and iso-propyl alcohols, acetone, methyl ethyl ketone, methyl n-propyl ketone, diethyl phthalate and methyl salicylate. Development of the colour is preferably effected by starting with the bath at low temperature, e.g., 20-30 DEG  C., and completing with the bath at a high temperature, e.g. 90-100 DEG  C.  Numerous examples are given.

Title: Improvements in or relating to float valves for petrol storage tanks
IPC: F16K31/22
Filed: 1928-06-14
Abstract: 292,471. Martini &. H³neke Maschinenbau - Akt. - Ges., (Assignees of Fabrik Explosionssicherer Gefõsse Ges.). June 18, 1927, [Convention date]. Direct liquid - pressure apparatus. - A float valve 8 or 18 for petrol reservoirs 1 with water a as the means for raising the petrol b is characterized by a guiding jacket 4 or 14 for the float 7 or 17, the jacket being in the form of an open pot the bottom 6 or 16 of which is formed as a non-return valve to allow liquid to pass out of the pot and to prevent its return. The floats are adjusted in weight so as to float in water and sink in petrol. In use, when the surface of demarcation 10 between the water and petrol lies between the two floats, as shown, the upper float 17 in the petrol b is in its lowermost position with the petrol exit valve 18 open, so that petrol is expelled through the pipe 12 when water is forced in through the pipe 2; at the same time the lower float 7 is in its uppermost position with the water entrance valve 8 open. The two valves remain in these positions until the water reaches the upper edge 15 of the jacket 14 whereupon the water overflows into the jacket, displacing the petrol therein, and causing the upper float 17 to rise and close the petrol exit valve 18. In a similar manner when the reservoir is being recharged with petrol the lower valve 8 closes when the water in the jacket 4 is replaced by petrol when the recharging of the tank is completed. The lower jacket is fitted with a hood 9 to shield the non-return valve 6 from sediment, and the upper non-return valve 16 is surrounded by a depending extension 19 of the jacket.
