Abstract: 1401666 Flame proofing textiles STAUFFER CHEMICAL CO 14 June 1972 [14 June 1971] 27730/72 Heading DIP [Also in Division C2] Textiles are flame retarded by applying thereto an effective concentration of at least one neutralised polycondensed vinyl phosphonate and thereafter curing the said vinyl phosphonate so as to form a fire retardant resin in and/or on the textile fibres. The polycondensed vinyl phosphonate is the substantially neutral product obtained by neutralising with an epoxide the acidic product obtained by heating a bis (2-haloethyl) vinyl phosphonate so as to effect its condensation polymerisation, halo being chloro or bromo. The term "vinyl phosphonate" is defined as including alphamethylvinyl phosphonate. The bis (2-haloethyl) vinyl phosphonate may be heated together with a bis (2-haloethyl) haloethylphosphonate, an inorganic acidic reagent or a tris (2-haloethyl) phosphate to obtain the acidic product. Curing of the vinyl phosphonate may be effected in the presence of a free radical initiating catalyst and/or by exposure to radiation. At least one additional comonomer may be applied to the textile together with the vinyl phosphonate and copolymerised therewith during the curing reaction. Numerous comonomers are specified, preferred comonomers being acrylamide and N-methylolacrylamide. The vinyl phosphonate may be applied to the textile in the form of an aqueous solution or a solution in an organic solvent, and padding baths containing the vinyl phosphonates are claimed per se.

Abstract: 1,089,941. Inverting; protective arrangements. INDUSTRIAL INSTRUMENTS Ltd. June 30, 1966 [June 30, 1965], No. 27748/65. Headings H2F and H2K. A driven thyristor inverter has voltage or current sensitive means to remove or reduce the input power in the event of commutation failure and means responsive to that removal or reduction to restore the input after a short period. The process is repeated several times if the fault persists; and then a further switch, preferably a slowacting thermal cut-out 12, turns off the inverter permanently. The inverter comprises thyristors TH1, TH2, commutating capacitor CC and transformer T1 When the input is switched on, transistors TR2, TR3 conduct to energize relay RL2 whose contacts RL2/1 connect the inverter to the supply through resistor R11. If the inverter operates correctly its output switches on transistor TR1 which energizes relay RL1 whose contacts RL1/1 connect the inverter directly to the supply. If the inverter fails to start the voltage across resistor R11 charges capacitor C2 and then, through transistor TR4, turns off transistors TR3 and TR2 and hence the inverter supply. When capacitor C2 discharges the circuit restarts automatically To facilitate starting without a load the dummy load R12 may be connected by relay RL3 until the inverter is operating normally.
