Patent GB-672669-A (GB)
Title: Improvements in or relating to the hardening of threads or filaments and apparatus therefor
IPC: D01D5/06
Filed: 1949-05-04
Abstract: A plurality of threads of filaments of <PICT:0672669/IV (a)/1> hardenable material is hardened by flowing a through a relatively narrow space between substantially flat confining surfaces at such a speed that the liquid flows through the space with viscous flow in the form of a substantially flat sheet, discharging a plurality of continuous liquid streams of hardenable material into the centre of the sheet, whereby the sheet supports and surrounds the hardenable material, causing the thread to harden while supported in the stream of hardenable material.  In an example, rubber latex is fed through a row of spaced nozzles 41 into the centre of the mouth 17 of a flat tube confined by plates 12 and 13 through which passes glycerine at 210 DEG  F.  Conditions are so arranged that the latex and glycerine pass along together with substantially no relative motion, and the hardened thread 44 leaves the tube and passes on to conveyer 45.  The glycerine is drawn from reservoir 5 where it is heated by coil 6, via pipe 8 to passages 10 and 11.  A constant head is maintained by the use of drain outlets 32 and 33 and return pipe 34.  The glycerine may be replaced by a hardening bath containing magnesium sulphate, zinc ammonium sulphate, acetic acid or formic acid, and the hardenable material may be a resin, plastic or metal.

Title: Improvements in and relating to methods of and means for producing voltages of rectangular curve shape
IPC: H02M7/51
Filed: 1936-05-04
Abstract: 479,510. Converting. BRITISH THOMSON - HOUSTON CO., Ltd. May 4, 1936, No. 12584. Void. Convention date. May 3, 1935. [Class 38 (ii)] Comprises an arrangement for producing peaky voltages by employing the difference between the moments of striking of two discharge devices. In the form shown in Fig. 1, the load 3, in series with a biassing battery 4 is connected across two resistances 12, 22 which are in series with valves 11, 21 connected across the A.C. source 7. The grid control of the valves is adjusted so that they conduct at different points in the half cycle. The valve 11 1 conducts, e.g. at the time tl , Fig. 2, so that the curve 5 represents the voltage of the point 5, Fig. 1, with respect to the cathode. The valve 21 conducts at the time t2 and the curve 6 represents the voltage of the point 6. The voltage between the points 5, 6 will be the difference of these curves, so that a voltage peak occurs between the times t1, t2 in each cycle. The waveform of the A.C. source 7 may be modified to give a flat topped positive half cycle by half wave rectification and biassing. In a modification the resistance 22 is omitted and the valve 21 has in series with it a bias battery. In a further modification, Fig. 9, two parallel type inverter circuits 1, 2 are supplied from tappings on a D.C. source 4, the load 3 being connected between the circuits. The valves 11<1>, 21<1> are controlled to conduct simultaneously and the valves 11 21 are controlled to conduct successively, the time interval between conduction being determined by a phase shifting circuit 37-39. The curves a and b, Fig. 10a, give the voltages across the valves 11, 21 and the voltage across the load 3 is the difference between these curves as shown in Fig. 10b. Correction for the variation in the difference voltage before and after the valves 11<1>, 21<1> have ignited may be effected by increasing the voltage on the valve 11. The inverters 1, 2 may also be supplied in parallel or in series from the D.C. source 4.

Title: A liquid-level warning device
IPC: F17C13/02
Filed: 1963-04-01
Abstract: 979,871. Fluid-pressure control valves. M-F. ADAGLIO. April 1, 1963 [March 30, 1962; Nov. 7, 1962], No. 12833/63. Heading F2V. [Also in Division G1] A device for warning of the level of liquid in containers for liquefied gases under pressure, e.g. propane or butane, comprises a tubular enclosure 25 fixed in fluid-tight fashion around the gas exit 13 from the container, and immersed in the liquid to beneath the level 24 at which the device is actuated, the enclosure 25 having a low cavity 38 containing a float 40, a stop permitting the float to rise only a specific height above its floating position on the liquid i.e. the level 24, and a valve seat opening into the volume of the container above the maximum liquid level 27, a valve 44 or 82 with a rod 41 or 81 respectively connected to (Fig. 1) or engaging with (Fig. 6) the float 40 so that the valve 44 is raised above its seat only when the liquid level is above the level 24 and a sounding- piece, e.g. the bottom 2 of the container or 84, on which strikes a hammer 45 on the rod or a boss 83 on the valve. In the device shown in Fig. 1, when the container is full, the valve 44 is raised clear of its seat and gas passes to the exit 13 through a valve 32 with a lip 36 which closes when there is excessive escape of gas. As the liquid level falls the float 40, which may be a hollow metal member or of cork, will eventually sink until the liquid reaches the level 24 when the hammer 45 strikes the bottom 2, and the valve 44 closes. Since this prevents gas escape to the exit 13, as the pressure rises, liquid is forced into the cavity 38 causing the float 40 to open the valve 44. The float again sinks and this process is repeated, the hammer 45 giving audible warning of the low level of the liquid. The hammer may be resiliently or loosely mounted on the rod 41 and in an alternative embodiment (Fig. 2, not shown), the valve 44 may be replaced by slide valves connected to the float by rods, which open and close ports in the upward extension 28 of the enclosure 25. The device shown in Fig. 6 acts in a similar manner, an audible warning being given by the boss 83 striking on the sounding- piece 84. Also in place of the valve 32 a cup 89 is provided on the rod 81, and excessive gas flow causes the cup to force the rod down against a spring 90 to close the valve 82. As a further alternative, the valve 82 may be replaced by a ball valve co-operating with a conical seating.
