Title: Improvements in or relating to the carroting of fur fibres for use in the manufacture of hats
IPC: D04H1/22
Filed: 1952-08-26
Abstract: In the manufacture of hat bodies from fur fibres, the fibres in the uncarrotted state are removed from the skins (e.g. hare and rabbit skins) and formed into cones in known manner, and the cones are impregnated with an aqueous solution of a carrotting agent.  A specified carrotting solution comprises 30 to 50 grams/litre of acid (nitric, hydrochloric) and about 10 to 30 grams/litre of hydrogen peroxide.  Solutions containing 10 to 25 grams/litre of urea nitrate, with or without hydrogen peroxide, may also be used.  The cone-liquor ratio may be from about 1 : 30 to about 1 : 50, so that the cones may move freely in the solution.  The cones may be slightly prefelted prior to carrotting.  The duration of the carrotting is dependent on the temperature of the solution, e.g. 1-2 hours at 80 DEG  C. or overnight at 40-50 DEG  C.  If desired, the cones may be impregnated at room temperature, excess carrotting agent removed and the impregnated cones allowed to lie about for 40 hours.  In a further modification the cones, after lying about for 1-2 hours, are heated to about 80 DEG  C. for 30-60 minutes.  In an example, cones are formed in the usual way from uncarrotted rabbit or hare fur and are moistened with hot water. The cones are then placed in an aqueous solution at 45 DEG  C. containing 35 grams of nitric acid and 15 grams of hydrogen peroxide per litre and left overnight.  After treatment is complete the cones may be worked up into hat bodies in the usual manner.

A detector 8 as described in Parent Specification is directed to receive radiation from a flame enveloping flame-holder 7 in the afterburner of a jet engine, solar radiation through the tail-pipe 5 being blocked by flame-tube 6 and flame-holder 7. Pulses at a frequency of 400 Hz from generator 22 are applied to the electrodes 19, Fig. 2 (not shown), of detector 8 and to counter 25 via potentiometer 23 and transistor 24. Discharge between the electrodes occurs only if sufficient ionisation exists, such ionisation being produced only when a flame is present. The potential of one of the electrodes is compared with a stabilized voltage by operational amplifier 26, the change in potential during a discharge generating a counter reset pulse. In the absence of a flame overflow of the counter 25 at a count of eight or sixteen triggers a transistor 28 to operate a relay 29 and close contacts 30. The control unit 31 may warn the pilot or initiate automatic relighting of the afterburner. The apparatus is said to be of advantage in avoiding nuisance operation of the unit 31. The detector 8 may incorporate a solid state sensor.
