Title: Processes for treating natural polyamides
IPC: D06M11/59
Filed: 1973-03-08
Abstract: 1372825 Treating natural polyamides with liquid ammonia OMNIUM DE PROSPECTIVE INDUSTRIELLE SA 8 March 1973 [14 March 1972] 11281/73 Heading D1P A process for improving the textile properties of natural polyamide fibres, especially polypeptide fibres, comprises contacting the fibres with liquid ammonia. The fibres may be in the form of a wad, flock, a thread, or a woven or knitted material, and may be wool, mohair or rabbit hair. The treatment may be effected at -33C at atmospheric pressure for at least one minute. Alternatively the treatment may be carried out at a temperature of 20C and under a pressure of 6 atmospheres. The fibres may be in a relaxed state. The material may be continuously moved during the treatment with the liquid ammonia, the speed of entry of the material into the liquid ammonia being adjusted to be greater than its speed of exit therefrom so as to compensate for shrinkage of the fibres as a result of the treatment. The process can be effected continuously or discontinuously. The liquid ammonia is removed by drying the material in the open air at ambient temperatures. Mixtures of fibres may be treated. The liquid ammonia may contain an adjuvant for example a softening agent or a dye. The process improves the unfelting and resistant to shrinkage on washing of the fibres, and provides a crimp in wool fibres which increases their elasticity.

[Also in Groups XIX and XXXVIII] In an epicyclic train, in order to equalize the load on the planets 3, the reaction annulus 4 is floatingly supported by a number of circumferentially spaced bell-crank levers 11, 8 mounted on fixed pivots 9, the arms 8 engaging in recesses 7 in the annulus and the arms 11 engaging an endless belt, cable or chain 14 arranged around the annulus. The annulus is thus held in a floating position and the reaction therefrom is taken up by the tension in the member 14. This tension can be measured to give a measurement of the torque transmitted through the gearing by a strain gauge consisting of a link 15 interposed in the tension member and carrying an electrical resistance element 16 secured to it. A second resistance element 17 on an unstrained limb of the link 15 may be utilized for temperature compensation. Another form of strain gauge which can be used comprises a device for measuring the natural frequency of vibration of the tension member 14 which comprises an electromagnet energized by an alternating current of adjustable frequency to excite vibration of the wire. The frequency is adjusted until resonance is obtained which is detected by a suitable form of pick-up. The tension and torque is proportional to the square of the resonance frequency.

Abstract: 1,171,102. Lasers. NATIONAL RESEARCH DEVELOPMENT CORP. 10 March, 1967 [16 March, 1966], No. 11614/66. Heading H1C. [Also in Division G2] A pulsed laser system includes a reflective surface rotating about an axis spaced therefrom to recurrently complete the resonant optical path of the system, the surface confronting but not wholly surrounding the axis. In one embodiment the reflector comprises a glass block 3 mounted in a cylindrical rotor 2 rotatable in air-bearings within a stator 1. Rotation is maintained by forming the assembly as an air-turbine The arrangement is such that a laser beam can be directed on to an end face of block 3 at the Brewster angle, be internally reflected off a side face and emerge from the opposite end of the block when the rotor is in an appropriate angular position. This arrangement may be used to optically couple two laser amplifiers intermittently in synchronism with the rotation of block 3, or may be placed between a laser active medium and a roof prism forming one of the resonator reflectors. Light incident on and reflected from the prism may follow the same or different paths. The arrangement may also be used to couple a laser active medium successively to each of a series of roof prisms lying on an arc swept by the beam emerging from block 3. In a modified arrangement the rotor and stator are open at one end only, the closed end of the rotor being connected to a shaft driven by an electric motor. The rotor and stator have windows which are aligned when block 3 is in the correct position to reflect light incident through the windows in a desired direction. This arrangement may be used with a ruby laser, the flash tube used for. pumping the ruby being synchronized with rotation of the block by means of a photo-cell arrangement coupled to the shaft of the electric motor. Corner reflector arrangements.-In these arrangements light incident on an end face is internally reflected from side and bottom surfaces and emerges from the same end face. Fig. 9 shows a hexagonal arrangement giving six reflections for each revolution of the rotor. To avoid undesired turbulence when the rotor rotates at high speed the outer surface of the block may be flush with the end of the rotor, the block being provided with a re-entrant portion to form a corner reflector with each reflecting side, as shown in Fig. 10.

Filed: 1940-07-12
Abstract: 581,562. Direct-call party-line systems; instruments. FOUNTAIN, Ltd., G. R., and SNELL, A. E. C. July 12, 1940, No. 11625. [Class 40 (iv)] In a telephone system for a submarine in which a central station is connected via an amplifier to a number of loudspeakers at out-stations, the operation of a key at an outstation couples the loud-speaker to a headphone at the central station to enable a reply to be given. To give an alarm, the input and output of the amplifier are coupled to cause it to generate a howler tone. As shown, operation of push-button 14 connects up the battery feed for microphone 1, preferably of the kind described in Specification 507,183 or Specification 537,524, via relay 31a which connects up the feed for an amplifier 4 comprising a pair of magneto - microphonic elements with their inputs in series and their outputs in a bridge arrangement. The amplifier units may be of the kind described in Specification 535,391. The output of the amplifier is fed via output transformer 46 to the out-stations. Operation of key 56 at these stations alters the connections of the matching transformers or auto-transformers so that the loud-speaker in question, which may be of the kind described in Specification 523,482, is connected in series with headphones 2 at the control station. On the operation of push button 65, relay AR is energized, operates winding b of relay 31 to switch on the amplifier, couple the input and output of the amplifier to cause it to howl and complete an additional circuit whereby the howler tone operates a distant loud-speaker even if the corresponding reply button is depressed. In the installation shown, the power is derived from the 20-volt mains of the submarine through suitable resistances 120 for the microphone and 121 for the amplifier. In certain cases, 121 may be shunted by a spare resistance 122. The microphone amplifier is housed in a resiliently supported moisture-proof casing provided with cooling fins. At the out-station a moistureproof box, Figs. 4 (not shown) and 5, contains the transformer and push-button and supports the loud-speaker.

Abstract: 1339034 Pipe couplings; valves DEMPCO Inc 28 April 1971 [7 May 1970] 11980/71 Headings F2G and F2V In an hydraulic circuit coupling an inlet valve 43 and a valve 26 in a releasable coupler 17 are opened by a cam 50 having high and low surfaces. In one embodiment, as shown, an intermediate valve 60 comprises a cam follower 63 on a double walled sleeve 64, 66 which slides in a main bore 32 and mounts a valve 69 urged by a spring 71. The releasable coupler 17 is coupled by locking balls 22 retained in a groove 21 by a spring sleeve 12. The coupler 17 includes a spring 30 which urges the valve 26 against a seat 27 and an 0-ring 29 seals the coupling. The cam 50, sealed in a transverse bore by 0-rings 51, is turned by a lever 55 through 90 degrees to bring low cam surfaces 58, (59) (Fig. 3, not shown), adjacent the valve 43 and follower 63. The valve 43 is then closed by a spring 45 and since the coupler spring 30 is more powerful than the spring 71, the valve 26 closes against seat 27 and the cam follower 63 enters the low surface 58 on the cam 50. When the coupler 17 is released by sliding the sleeve 12 past the locking balls 22, the valve 69 is urged closed by the spring 71. During recoupling of the coupler 17, the valve ball 26 unseats the valve 69 because of the greater strength of spring 30 and a small quantity of the fluid which was trapped by the intermediate valve 60 is bled off through bleed passageways 72, 77, 78 when the passage 72 clears an 0-ring 76 which, together with another 0-ring 75, seals the passageways 77, 78 during flow through the coupling. Alternative arrangements for relieving the pressure in the intermediate valve chamber include a plunger (89) (Fig. 5, not shown) working in a bore through the valve 69 and stud 68 which contacts the valve 26 upon insertion of the coupler 17, or bleed passageways (94, 96, 98) (Fig. 7, not shown) in the cam 50 and body 11 connect the main bore 32 with the exterior when the cam is rotated to close the valves 43, 26.
