Title: Improvements in fluid control valves
Inventor: LANGFORD CECIL CHARLES
IPC: F16K1/46
Filed: 1958-01-16
Abstract: 849,942. Valves. DAMIC CONTROLS Ltd. Jan. 14, 1959 [Jan. 16, 1958], No. 1589/58. Class 135. A fluid control valve comprises a body having an inlet connection 2 and an outlet connection 3 and a valve closure member 5 biased in a closing direction by a light spring 16. The closure member 5 is provided with an axial passage 29 whereby the pressure of fluid acting on the closure member in a direction tending to displace it from its seating is also applied to the rear face of the valve member, the fluid passing through radial passages 32 at the rear end of the valve member. The effective cross-sectional area for partial counterbalancing purposes is slightly greater than the cross-sectional area of the valve face. The closure member is constructed in two parts 7 and 9 in threaded engagement with each other, the two parts together providing an annular groove housing a resilient " O " ring 11. The valve spindle 18 may be activated manually, pneumatically or by means of a solenoid, the core of the solenoid being coupled to the extremity of the spindle on the occurrence of an excess inlet pressure, the valve will open and function as a pressure relief valve.

Title: Improvements relating to the manufacture of activated carbon
IPC: C01B32/384
Filed: 1935-01-21
Abstract: Active carbon in moulded form is obtained by treating organic material, e.g. sawdust, peat or lignite, preferably powdered, with known activating or carbonizing agents, such as zinc chloride or phosphoric acid in the case of chemical activation or dilute sulphuric acid in the case of gas activation and heating it to a temperature between 100 and 200 DEG  C. while stirring, until the carbonized mass assumes a kneadable and plastic form when it is moulded under pressure, and baked till hard, preferably in the presence of oxygen, at a gradually increasing temperature so that the shapes do not sinter or melt.  The material is then gas activated at high temperature or activated by heating to a temperature of 450 to 600 DEG  C.  The die of the moulding press is preferably heated to about 100 DEG  C. to avoid interrupton of the heat treatment.  Excess activating agent may be washed out with water or acid.  If desired, the moulding process may be assisted by the addition of known binding agents, preferably during the heating and mixing process and when the mixture has attained some degree of plasticity.  Activating agents may also be added at this stage.

Abstract: 997,364. Insulation testing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 31, 1962 [Jan. 18, 1962], No. 1924/62. Heading G1U. In a device for testing insulation a high voltage transformer TS applies voltage over resistor R L , an outer double ended shielding skirt 7, inductor L 1 , an inner single ended skirt 6, inductor L 2 , and conductor 3 to insulating body e.g. capacitor C X -under test. A coupling capacitor Cc within the lower inner and outer skirts couples discharge oscillations from conductor 3 to an amplifier (not shown) and a detecting or measuring device (not shown) e.g. an oscilloscope, the line being coaxially shielded by screens 4, 5 connected to the inner and outer skirts. The discharge oscillations may be in a 10 Kc/s band width of a 500 Kc/s carrier and a skirt capacitor CF within the upper skirt is connected between the inner skirt and earth. Inductor L 1  forms a parallel tuned circuit in the outer skirt capacitance to present high impedance to incoming noise at discharge frequency, while inductor L 2  forms a parallel tuned circuit with the capacitance between the inner skirt and the conductor repeating discharge oscillations which are directed to the detector over C c . Other incoming noise is reduced by stray capacitance C S  in conjunction with R L . The screening members may be metal sheet or mesh, and an inductor may be connected in series with C F  to provide a low impedance series tuned path for input noise at discharge frequency.

Abstract: 339,843. Ellingson, E. Jan. 21, 1930. Night latches; latches, preventing operation of.-A rod sliding in a recess in the knob spindle can block the catch, render both knobs inoperative or render the outside knob inoperative. The rod 51 slides in the recess 19 in the spindle 14 and carries a latch-blocking projection 54 and a projection 53 which can engage a recess 44 in the rose-plate 28 of the outside handle 37 to render the spindle non-rotatable. The end of the rod is secured to a member 41 which couples the outside knob to the spindle 14 by engaging a recess 50 therein. When the rod is pushed fully inwards, the member 41 is clear of the spindle and legs 43 on it are held in recesses in the rose-plate. Fig. 2 shows the device in the unlocked position, the knobs being turnable to retract the latch bolt 2, by the follower 12, the shank 7' of the bolt entering between the lugs 54, 53. If the rod 51 is pushed in by the button 52 or pulled in by the cylinder lock 38', the projection 54 blocks the latch, and the projection 53 and legs 43 enter the recesses in the roseplate. If the rod is half pushed in, the projection 54 is moved so that the inclined part 56 is opposite the latch, but the legs 43 are in the recesses in the rose-plate. Operation by the outside knob is impossible without first turning the key, in this position, but operation by the inside handle restores the rod to full unlocking position.

[Class 81 (i)] [Also in Group IV] A composition suitable for use as a drying ointment is prepared by forming in a solution of an alcohol-soluble phenol-aldehyde or a phenolketone resin a gel of an alcohol-insoluble ureaaldehyde or urea ketone resin ; alternatively, in a solution of a urea-aldehyde or ketone resin in the water soluble state there is formed a gel of an alcohol insoluble phenol aldehyde. or ketone resin. The first-mentioned composition may be prepared by mixing a phenol with considerable excess of formaldehyde and an alkaline condensing agent, heating for ¢ to 1 hour, evaporating most of the water, adding sufficient urea or thiourea to combine with the excess formaldehyde and heating, but not sufficiently to produce the gel condition ; the alkaline condensing agent may be neutralized or washed out and alcohol or other solvent is added whereafter on standing the urea-aldehyde compound will precipitate and transform the alcohol solution into a gel. Or the urea may be first condensed with excess aldehyde and the phenol then added. Emulsifying agents may be added to the ointments and stabilizing agents, e.g. sodium salicylate or sodium benzoate. In producing a composition of the alternative type in which insoluble phenol resin is suspended in soluble urea-resin, phenol, excess of formaldehyde and soda are heated under reflux, 90 per cent of the water of the formaldehyde is distilled off, urea is added to combine with the formaldehyde and after heating the alkali is neutralized with an acid which may be in excess ; the mass is heated to 100‹C. and the hot mass is mixed with aqueous alcohol. The solution formed sets to a jelly on cooling.
