Title: Improvements in or relating to self-opening screw-cutting die-heads
IPC: B23G5/12
Filed: 1926-03-08
Abstract: 257,182. Jackson, L. Mellersh-, (Geometric Tool Co.). March 8, 1926. Screwing die-heads.-In a stationary or rotary self-opening die-head of the kind in which the chasers are adjusted by an axially sliding sleeve, the sleeve is locked in the operating position by an internal segmental block which is pressed radially outwards by springs but may be depressed inwardly to release the chasers by a pivoted tripping member. The chasers 40, pressed radially outwards by spring plungers 43, are adjusted by a sliding sleeve 12 having an internal annular recess 27, Fig. 3, which is eccentric with regard to the axis of the head. In an annular recess 19 in a second sleeve 20 is seated a stationary segment 23 having springs 25 at its ends which tend to press a segmental block 18 into the eccentric recess 27. In operation, the die-head is closed by moving the sleeve 12 forwards against the action of axial springs 37, a cam portion 44, Fig. 2, on the block 18 forcing the block inwards to allow the sleeve to pass. When the chasers are in the cutting position, the block springs outwards into its eccentric position and locks the sleeve until a stop on the machine engages a projection 17 on a trip lever 10, Fig. 3, pivoted in the sleeve, and thus forces the block out of the eccentric recess 27. The closed position of the chasers may be varied by adjusting the sleeve 20 axially by means of its internal screw-thread. The sleeve 12 is guided axially by two pins 35 sliding in an enlargement 22 of the body 21, and a screw 34 having a reduced end engaging an axial recess 32 in the segment 23 limits the motion of the sleeve in both directions. A key 29, Fig. 3, prevents rotational movement of the segment 23, and a pin 16 engaging an enlarged hole 15 in the tripping lever 10 limits the oscillation of the latter.

Filed: 1946-03-02
Abstract: 615,987. Valve amplifying circuits. PHILIPS LAMPS, Ltd. March 2, 1946, No. 6563. Convention date, March 3, 1945. [Classes 40 (v) and 40 (vi)] A reflex circuit for amplifying first a high or intermediate frequency signal and then the modulation derived therefrom by detection has negative feedback applied at modulation frequency in order to reduce the demodulation of the signal caused by non-linearity of the reflex amplifier. As shown, the incoming signal is inductively applied to tuned circuit 1 connected to the second control grid of heptode valve 2. The amplified signal appearing at the anode is passed via tuned circuits 3 and 5 to the detector circuit, the L.F. output of which appearing across potentiometer 7 is fed back to the first control grid of the heptode. An amplified L.F. signal is developed at the screen-grid and this is applied via coupling condenser 13 to the second control-grid to produce a further amplified signal across loadresistor 4 in the anode circuit. This is fed via an I.F. filter to the grid of amplifier valve 8. Valve 2 is neutralised at I.F. by means of condenser 21, condenser 22 being provided to swamp variations in inter-electrode capacitance. Negative feedback is applied to the reflex amplier at modulation frequency from the anode circuit through resistor 23, condenser 24 and tuned circuit 1 to the second control grid and also from the output transformer of valve 8 to both the cathode via resistor 25 and to the second control grid via condenser 28. Since distortion is thereby kept small a.g.c. may be applied to valve 2, the control voltage being obtained from the diode load resistor 6 and applied to the first control grid. In an alternative arrangement the second stage of L.F. amplification is omitted in which case the L.F. signal for amplifier 8 is taken from the screen grid.

Title: Improvements in or relating to the production of hypochlorous acid gas
IPC: C01B11/04
Filed: 1946-03-12
Abstract: Hypochlorous acid gas is produced from airborne aerosols of hypochlorites in which a hypochlorite is mixed, either before or after the formation of the hypochlorite aerosols, with a suitable weak acid to release hypochlorous acid gas, which is distributed to any required point or points of discharge through one or more pipes or conduits forming part of the gas producing system in which the process is being carried out and wherein unconverted aerosols and other extraneous matter are removed wholly or largely from the gas prior to discharge.  Gasification may be expedited by (a) a drop in pressure, e.g. by passing the aerosol-charged air into a chamber, preferably immediately prior to filtration, to allow expansion; (b) maintaining the humidity of the air by <PICT:0631796/III/1> <PICT:0631796/III/2> steam injection, and (c) warming the air or pipes and chambers through which the aerosols pass.  Atmospheric carbon dioxide or weak acids, e.g. boric acid may be used to liberate the hypochlorous acid gas from the hypochlorite.  In a suitable apparatus for carrying out the above process, a fan c in casing c1 impels air along a conduit e across a jet f through which is drawn aqueous hypochlorite to form hypochlorite aerosols, which along with excess air drawn through cones g and vents i pass to a fan d and casing d1.  Both fans are driven by a motor b mounted on a base-plate a.  The turbulence created by the fan d in conjunction with atmospheric carbon dioxide causes gasification of the aerosol to hypochlorous acid gas, which is passed through a duct d2 to a purifying chamber k provided with filter units l containing glass wool and through which it is drawn by fan m driven by a motor n into a discharge duct m2.  Drains are provided in the chamber k and adjacent pipes for the removal of condensed hypochlorites. Specification 608,140 is referred to.
