Patent GB-548906-A (GB)
Title: Improvements in or relating to the preparation of modified alkyd resins
IPC: C08G63/553
Filed: 1941-03-21
Abstract: 548,906. Modified alkyd resins. BRITISH RESIN PRODUCTS, Ltd., and WILSON, J. J. March 21, 1941, No. 3884. [Class 2 (iii)] A process for the preparation of a modified alkyd resin comprises the step of modifying a natural resin by heating it with a drying oil, or its fatty acid, in such a manner that the natural resin thus modified is, at room temperature, still a solid compound, prior to incorporating and condensing it, with the aid of heat, with a polyhydric alcohol-polybasic acid condensation product, or the components thereof. When the natural resin is to be modified with a drying oil, these two materials should be heated together until some double decomposition (ester interchange) has taken place. The modified natural resin may be heated with the polycarboxylic acid prior to the addition of the polyhydric alcohol, or the two latter substances may be added simultaneously. Alternatively, the modified natural resin may be heated with a partly condensed polyhydric alcohol-polybasic acid reaction mixture, and condensation then completed. Examples are given of the production of resins from : (1) gum resin, dehydrated castor oil, maleic anhydride and glycerol; (2) wood resin, tung oil, maleic anhydride and glycerol; (3) rosin, tung oil, maleic anhydride and di-ethylene glycol; (4) rosin, linseed oil, maleic anhydride and glycerol.

Title: Improvements in or relating to variable-pitch propellers
IPC: B64C11/38
Filed: 1947-02-14
Abstract: 624,579. Variable-pitch propellers. ROTOL, Ltd., and CHILMAN, J. A. Feb. 14, 1947, No. 4352. [Class 114] Heating circuits are provided for the blades which are operative during normal pitch running but which are disconnected during reverse pitch operation. The heating current is supplied from the generator 31 to the blade heaters 30 through the switch 32. To bring the propeller to reverse pitch the switches 37, 38 are operated successively, the first operating solenoid 36 to bring switch 32 to its lower position, breaking the heating circuit. Switch 38 operates solenoid 41 which through a valve overrides the governor control, and also solenoid 43 which prevents reverse movement of the governor control. A hub mounted switch 35 closed only when the generating piston has moved outside its normal operating range operates solenoid 40 to complete a holding circuit for solenoid 36. In bringing the propeller back to its normal operating range switches 38, 37 are opened in that order and a lost motion on switch 35 ensures that this switch does not open until the desired range has been reached, when the heating circuit is re-connected.
