Title: Improvements in or relating to printing telegraph apparatus
IPC: H04L19/00
Filed: 1937-01-12
Abstract: 490,413. Type printing telegraphy. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. Jan. 12, 1937, No. 16710/38. Divided out of 490,361. [Class 40 (iii)] In a step-by-step telegraph receiver, the printing-hammer is actuated automatically on the return movement of a lever thrown rapidly away from a cam wheel rotating with the type wheel and delayed in its return movement after the rotation has ceased. A threearmed lever 47, 48, 49 mounted on a pivot 51 is thrown away from a star wheel 53, rotating with the type wheel shaft, by means of a roller 52 carried on its arm 48. Its return movement is delayed by means of a ratchet driven escapement 55 connected to its arm 49 so timed that the roller 52 cannot return into a hollow of the star wheel 53 until after the latter has ceased to rotate. As the arm 47 moves to the left it allows a rod 44 carried on a spring mounted lever 45 to rise slightly behind it and on its return movement it tilts this rod further and with it a frame 41, the lower end of which normally holds a detent 38 in the path of a wheel 37. The tilting movement of the frame 41 releases this detent, allowing rotation of the wheel 37 and shaft 35 through a quarter of a revolution, the whole mechanism being reset immediately by the co-operation of a cam wheel 62 with a roller 61 associated with the detent 38 and lever 45. On the shaft 35 is mounted a four lobed cam, Fig. 4 (not shown), which at each quarter revolution throws upwards a frame to which are pivoted the printing-hammers, these being carried on to the type wheels by their momentum acquired when the frame is stopped by a paper shield. Specification 490,361 is referred to.

Title: Improvements in or relating to the treatment of textile materials
IPC: D06M11/71
Filed: 1931-06-11
Abstract: In order to raise their safe ironing point, materials made of or containing cellulose esters and ethers are treated with a solution of a weighting metal salt in presence of a substance which represses swelling of the cellulose compounds after which the metal is precipitated as an insoluble compound.  The substance repressing swelling may be a substantially neutral salt, e.g. sodium, potassium or calcium chloride, or other halide of an alkali or alkaline-earth metal, preferably having the same anion as the weighting salt.  It may be present in the proportion of 10-40 per cent of the other constituents of the treating solution. Suitable weighting salts are chlorides or other compounds of tin, zinc, aluminium, bismuth, tungsten, or antimony.  Stannic chloride may be used as a solution of 1-10 per cent strength, particularly 2-6 per cent, at a temperature of 50-95 DEG  C., the higher temperatures being suitable with lower concentrations.  The treatment in such baths may last from 30 minutes to 3 hours, and may be carried out by suspension of the fabrics in the solution or by means of a winch or jig, or by padding appliances, or by simple immersion of yarn in hank form.  After squeezing, centrifuging, or the like, the goods are treated with fixing liquids, e.g. solutions of tri- or disodium phosphate, silicates, or tannic acid.  A small proportion of the weighting metal is sufficient to raise the safe ironing point considerably, for instance less than 10 or even less than 1 per cent.  The process may be applied to mixed fabrics, containing for instance threads of natural silk or regenerated cellulose in addition to threads of cellulose esters or ethers.
