Title: Improvements relating to the treatment of textile fabrics
IPC: D06M15/41
Filed: 1936-08-15
Abstract: Cellulosic fabrics are rendered resistant to shrinking and stretching without affecting their creasability and suppleness by impregnating with an aqueous solution of an artificial resin precondensate of the phenolic or carbamidic type, drying at the desired final dimensions, and heating to insolubilise the resin, so that the resin content of the fabric is not more than 8 per cent by weight.  In examples, viscose staple fabric, viscose cr<\>zepe fabric, cotton voile, cotton poplin and a mixed cotton-viscose fabric, are treated with urea-formaldehyde initial condensate acidified with acetic acid, dried under tension and subsequently heated, the finished materials containing 2-5,9 per cent of the resin.  By drying without tension after impregnating, but otherwise treating as above, extension of the fabric whilst damp and hot-ironed is substantially reduced.

Title: Improvements in or relating to electron discharge devices utilising cavity resonators
IPC: H01J25/52
Filed: 1946-08-01
Abstract: 618,268. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Aug. 1, 1946, No. 22997. Convention date, Aug. 20, 1945. [Class 39 (i)] An electron discharge tube of the velocitymodulation type such as the reflex type described in Specification 535,767, has a resonator tuned by producing within it a rotating electron cloud or space charge, and having means for varying the density of the space charge or cloud and/or the angular velocity thereof. As shown, the resonator shell 11 has a tubular re-entrant portion 17 and a tubular pedestal 19. The latter contains a cathode 25 and heater 27, the electron beam from which is directed by a collimating shield 33 through the resonator space between grids 23, 21 and returned therethrough by reflector electrode 35. Coaxially mounted within the resonator is an auxiliary cathode structure comprising a doublewalled cylinder 55 containing a heater coil 49 connected to the cylinder at one end 65, its other end passing through the interior of tubular conductor 59 to battery 63. Tube 59 supports the auxiliary cathode and completes the battery 63 circuit, also forming the inner conductor of a coaxial line whose outer conductor 61 is rigidly secured to or integral with the end wall 13 of shell 11. Filter sections 67, 69 act as quarter-wavelength filters isolating the heater circuit from the high-frequency energy within the resonator. The outer surface of cylinder 55 has an electron-emitting coating 57 and a concentric cylindrical anode 71 is mounted on a conducting rod 73 passing through a coaxial line similar to that above described. Battery 81 maintains a potential difference between the auxiliary electrodes, the corresponding electron flow being forced to traverse a spiral path by an axial magnetic field produced by a coil 85 enclosed by a soft iron shell 89, or alternatively by a permanent magnet with variable shunt. The dielectric constant of the rotating electron cloud, and hence the natural frequency of the resonator, is varied (1) by altering the radial electric field strength of the rotating cloud by varying battery 81, or (2) by altering the angular velocity of the cloud by varying the magnetic field via battery 87, or by both methods in conjunction. A frequency modulation signal voltage may be applied by means of a transformer in series with battery 81, or battery 87, or both. In a simplified modification (Fig. 3, not shown), the cylindrical wall of resonator 11 acts as the auxiliary anode and is insulated from the re-entrant portion 17 which acts as the auxiliary cathode. The latter has the emissive coating on its outer surface, the heater coil being mounted interiorly. A battery maintains between the auxiliary electrodes a variable potential difference applied through a radio-frequency filter arrangement. Specification 555,825 also is referred to.

Title: Improvements in and relating to the production of iron powder
IPC: B22F9/22
Filed: 1945-11-13
Abstract: Ferrous chloride crystals used for the production of iron powder are produced from liquor, e.g., spent pickle liquor which usually contains free hydrochloric acid by neutralising the liquor with scrap iron or other reagent such as ammonia or iron hydroxide and recovering the chloride as crystals from the liquor by spray drying or evaporation and crystallisation.  The crystals are obtained in the dihydrate or tetrahydrate forms or a mixture of these hydrates, the preferred form being the dihydrate which is produced directly by crystallisation at above 70 DEG C. or by rapid drying of the tetra-hydrate which is provided at temperatures below 70 DEG C.ALSO:Iron powder is produced by subjecting ferrous chloride crystals to heat treatment at 500-600 DEG  C. in a reducing atmosphere of hydrogen, bringing the iron powder so produced into intimate association with water to remove unreduced material, e.g. by milling it in the presence of water and then densifying the powder by heat-treatment in a reducing or non-oxidizing atmosphere at 600-850 DEG  C.

[Also in Division B7] An aircraft instrument producing an electrical signal when the aircraft approaches its maximum permissible speed comprises static pressure and airspeed detectors connected by a linkage when the aircraft approaches said speed, whereby the signal is produced, the linkage comprising a first member driven by a detector and a second member driven by the first by means of a plurality of co-operating pairs of lever arms of different drive ratios which become operative during different parts of the range of displacement of the members. The interior of a housing 14 is maintained at static ambient pressure by a connection 17, the interior of a capsule 15 is connected to the total pressure orifice of a pilot tube by connection 18, and the capsule is connected by mechanism 22, 24, 26 and 27, to a shaft 20 having arms 39, 40, 41, adapted to engage arms 36, 37, 38, respectively, on a shaft 19 biased by a hair spring 42. Within successive ranges of movement of shaft 20, drive is transmitted to shaft 19 through the three pairs of conducting arms respectively, so that the velocity ratio between the shafts varies discontinuously through the range of movement. Shaft 19 is earthed, and has an arm 31 adapted to make electrical contact 32 on a sealed capsule 16, from which a lead 34 extends to a relay, and a conductive stop screw 44 is connected by lead 46 to the relay so that the relay is energized whenever the relationship between airspeed, measured by capsule 15, and static pressure, measured by capsule 16, is such that the airspeed approaches the maximum value allowable at the prevailing static pressure. Energization of the relay may actuate an audible or visual signal, or may automatically reduce the airspeed. The relative lengths of the lever arms, and their positions on the shafts, which determine when one pair of arms supersedes another pair as operative, may be adjustable.
