Title: Improvements in and relating to wrap striping or patterning in knitting machines
Inventor: DEANS FREDERICK EDWARD
IPC: D04B9/18
Filed: 1945-09-12
Abstract: 650,664. Knitting-machines. BENTLEY ENGINEERING CO., Ltd. Sept. 12, 1945, No. 23470. [Class 74 (ii)] A wrap thread is fed to selected needles of a group of needles prior to the needles of the group clearing their previous course loops. The invention is described in connection with a superimposed needle cylinder machine and has mechanism as disclosed in Specifications 650,662 and 650,663 in which wrap threads are fed from two fingers 6, 6a adapted to be deflected in the direction of rotation of the needles, rocked across the needle circle, held stationary whilst a group of needles pass the finger and then withdrawn across the needle circle to complete a wrapping operation. The wrap thread is fed above the spoons of the open latches of selectively raised needles of the group and above the previous course loops, the selected needles being raised above the rest but not sufficiently to clear the previous course loops. On completion of the wrapping movement, the needles, continuing to rotate, are cleared of their previous course loops and a new course thread is fed to them. The new stitch loops together with the wrap thread loops are then pulled through the stitch loops of the previous course. To prevent the wrap thread loops being cleared at the same time as the previous course loops prior to the feeding of a new thread, a separator 34, comprising a wire connected to one edge and extending across a gap 36 in a stationary tube 35, is positioned directly adjacent the plain side of the needles. The wire also extends from the commencement of the wrapping zone to beyond the clearing point and is positioned so that the wrap thread is fed over the wire to the needles and held separately from the previous course loops until these loops have been cleared. The wrap thread then passes off the end of the wire but remains above the spoons of the open latches ready to co-operate with a new course thread to be drawn through the previous course loops. Specification 400,623 also is referred to. Reference has been directed by the Comptroller to Specification 526,963.

Title: Improvements in or relating to manufacture of ammonium sulphate
IPC: C01C1/242
Filed: 1953-08-27
Abstract: In a cyclic process for recovering ammonia from ammonia-containing gas, <PICT:0773147/III/1> e.g. coke oven gas by scrubbing such gas in an absorption zone with mother liquor from an ammonium sulphate crystallization stage comprising a vacuum evaporator and crystallizer, said liquor comprising an aqueous sulphuric acid solution saturated with ammonium sulphate and containing ammonium sulphate nuclei, and returning the liquor after absorption of ammonia to the crystallization stage, the humidity of the gas and the temperature of the spray liquor are controlled so that the dew point of the gas after contact with the spray liquor is equal to, or less than, the dew point of the gas before contact.  The temperature of the spray liquor is controlled by means of the vacuum evaporator which may be operated at an absolute pressure of up to 6 in. of mercury.  The humidity of the gas being scrubbed may be 32-60 DEG C. The process is regulated by the above means, and in addition by the addition of necessary make-up water, so as to prevent the spray liquor from becoming substantially supersaturated.  The concentration of ammonium sulphate is preferably kept below 101.5 per cent saturation.  Make-up water (in addition to that condensed from the scrubbed gas) may be added as such or in the form of aqueous sulphuric acid, e.g. 60 DEG  Baum<\>ae acid.  The make-up acid is preferably added after the absorption step, but some or all may be added during the absorption step, e.g. in order to wash down the internal walls of the absorber.  A limited amount may also be added before the absorption step, provided that such addition does not result in the solution of all the nuclei.  Coke oven gas from the primary cooler of a coke plant may be treated with ammonia-still vapours so as to increase its water vapour content, and then passed to the absorption stage.  As shown ammonia is scrubbed in an absorption vessel 10 with desaturated solution from a crystallizing vessel 28 via pipe 16 and pump 40.  The solution after absorption is passed through pipe 20, wherein it is mixed first with make-up acid from pipe 22 and then with desaturated solution from the crystallizing vessel via pipe 30 and pump 26, to evaporating vessel 34 via pipe 32, and then to crystallizing vessel 28 via pipe 36, whereafter it is recycled to the absorption and evaporating vessels.

Title: Improvements in and relating to electric relay apparatus
IPC: H03K5/04
Filed: 1936-08-31
Abstract: 466,392. Valve relay circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 31, 1936, No. 23800. Convention date, Aug. 30, 1935. [Class 40 (v)] To ensure the operation of an electromagnetic relay device in response to an electric impulse the duration of which may be shorter than the time constant of the device, a grid-controlled electric discharge valve is connected in series with a condenser across a D.C. supply, the relay device being connected across the condenser and a blocking bias potential is normally applied to the grid, the electric impulse being arranged to remove the blocking potential from the grid. As shown in the Figure, in which the relay arrangement is adapted to respond when holes occur in a paper strip 20 moved between brushes 23 and a metal plate 22, the relay coil 10 is connected across a condenser 3 arranged in the circuit of the anode 5 of a thermionic valve 4. The grid 7 normally has -a negative bias applied through a resistance 8 which may be overcome momentarily on bridging of contacts 22, 23. The brief current impulse is insufficient to cause operation of the relay owing to time constant of the winding but the condenser 3 is charged. The valve immediately again becomes nonconducting but the charge acquired by condenser 3 equalizes through the relay winding causing it to become energized sufficiently to operate. In addition to closing a controlled circuit 13 the relay completes at 14 a maintaining circuit which may subsequently be broken at a push-button 17.
