Title: Improvements in apparatus for delivering liquids by gaseous pressure to spraying devices
IPC: B05B9/08
Filed: 1956-09-21
Abstract: 793,682. Forcing liquids by gaseous pressure: air compressors. HUDSON MANUFACTURING CO., H. D. Sept. 21, 1956 [Oct. 14, 1955], No. 28951/56. Classes 8(1) and 102(2). A tank 10 having a connection 34 to a spray device has a filling opening 43 in which an air pump cylinder 14 is removably disposed. The cylinder 14 has an enlargement 26 which may be passed through the opening 43 into the tank, thereafter a sealing sleeve 28 mounted on a head 16 and surrounding the cylinder 14 is pushed over the enlargement 26 and becomes of a diameter to seat on the opening 43 under the influence of a spring 38. Hooks 41 on the head 16 are engageable by recesses 42 in the pump operating handle 32 to force the head 16 down, or by the handle to lift the container or by the fingers to withdraw the head 16 while the cylinder 14 is pushed down by the handle, to enable the pump to be removed and. the tank filled. The pump is provided with an outlet valve comprising an elastic band 35, supported between a further cylinder enlargement 27 and a flange 30, controlling ports 37. The piston packing flange 18 flexes into the enlargement 27 and in its lowest position is spaced from the bottom 23 by a flange 22. In the upper position of the piston air enters the cylinder freely via the enlargement 26.

Title: Automatic fishing machine
IPC: A01K89/017
Filed: 1964-07-14
Abstract: 1,025,415. Winches; end stop gear. TÀ CHRISTIANSEN. July 14, 1964, No. 28986/64 Heading B8B. [Also in Divisions A1, F2 and H2] An automatic fishing apparatus comprises a pulley 21 for a fishing line and an electric motor M for driving the pulley through an electromagnetic coupling 22 to give a jigging action to the line. The driving shaft of the pulley operates, through gears 23, 24 and a worm gear 25, 26, two cam discs 28, 30 arranged to throw two switches 13 and 12. On closure of the main switch 19 the motor M is energized but the coil 1 of the coupling remains deenergized so that the line is released by the pulley and drawn out by the weight of an attached sinker until the depth limit switch 12 is moved to position a by cam disc 30 whereby the relay 6 is energized to energize the coil 1 of the coupling. Referring to Fig. 1 (not shown), a capacitor 20 delays the operation of relay 6 so that the line drops a further 1 to 1À5 metres before the coupling operates to withdraw the line. When the cam disc 30 again moves the switch 12 (to position b) the coil 1 is de-energized so that the coupling is released and the line is again drawn out by the sinker to repeat the jigging operation. If a fish is hooked during the raising movement of the line, this imposes a greater load on the motor whereby increased rotor current operates relay 4 which operates relay 3 so that the coil 1 is energized independently of relay 6 whereby the fish is continuously drawn in until cam disc 28 opens switch 13 to de-energize relay 5 to stop the motor. This can be restarted by opening switch 14 to deenergize relay 3. The relay 3 also puts resistor 9 in the stator circuit instead of resistor 10 so that the " hauling-in " speed of the motor can be different from the " fishing " speed. In an alternative form of fishing the length of the reciprocations of the line are controlled, with switch 15 closed by a thermo-relay 7 which delays the operation of relay 6 by 3 to 30 seconds depending on the adjustment of resistor 16. For use as a winch operation of a double-pole switch 17 renders the limit switch 13 inoperative and the motor may then be controlled by switch 18.

Abstract: 933,043. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 11, 1961 [Aug. 13, 1960], No. 29083/61. Class 40 (4). The battery B at a remote exchange V is charged from a central exchange Z over as many of the lines between the exchanges as are not involved with calls, the battery B being charged over a resistor RV and loads V1 being supplied over rectifiers G1 and G2 as shown. Loads V2 may be supplied direct from the battery B. Inter-exchange lines RL that are not employed with calls are connected, over contacts such as ta, tb, to the central ecxhange current source Q and to the terminal of resistor RV remote from battery B. If the demands of load V1 become so large that the drop in the lines RL reduces the voltage supplied over rectifier G1 below that of battery B, rectifier G2 conducts so that B contributes to the supply. If all the lines RL are in use, the battery B is the sole supply at the remote exchange.

Title: Electro magnetic relay for indicating current direction irrespective of polarity or strength
IPC: H01H47/16
Filed: 1922-10-26
Abstract: 208,305. Preston, L. C. Oct. 26, 1922. Order apparatus.- An unpolarized indicator or relay is so constructed and arranged in a line that its armature is deflected in one direction by anv current from the down station. The field coils 'a, b are of low resistance and are in series in the line while the coil c for polarizing the armature e is of high resistance and is in leak to the earth or metallic return E. If the relay be arranged near one end of the line, the effects upon it of the near and distant stations will be unequal, but this inequality is compensated by means of adjustable pole-pieces f and g. The armature is adapted to make contact at k or and is prolonged by a centring spring h along which can be adjusted a pillar j having a slot by which the spring is held. Audible or visual indications may be given either by apparatus controlled by the contacts k, l or mechanically by means of the armature movement.

Title: Improvements in the production of very finely divided solid substances with a low bulk density
IPC: B01J13/00
Filed: 1954-10-13
Abstract: Aerogels are continuously prepared by pumping a colloidal solution through a heated tube (2) at at least the critical pressure of the dispersion medium and released at the end of said tube &c. by pressure reducing means (3) to a substantially lower pressure e.g. atmospheric, separating the mixture of solid substance and vapour before condensation of the vapour.  The temperature at least at the end of the tube &c. is not less than the critical temperature.  The numerals relate to the drawing in which the separation of aerogel and dis <PICT:0773549/III/1> persion medium vapour takes place in a cyclone 4 which may be heated to prevent condensation and the separated materials are collected in vessels 7 and 6.  A stream of inert gas such as nitrogen is led through the container 7 for aerogel.  The heating may be electrical or with hot gases or by the use of baths e.g. of diphenyl or lead.  Preferably two or more cyclones are used in series.  In examples, (1) a 6 per cent silica sol in methyl alcohol (produced by peptizing a gel) is expanded at 270 DEG C. and 90 ats. to give particles of size 13-20 millimicrons (2) a 10 per cent aqueous methyl alcohol silica sol (produced by peptizing a hydro-gel with ammonia under pressure at 170 DEG , concentrating to 30 per cent and adding methyl alcohol) is expanded 320 DEG C. and 150 ats. to give particles of size 10-30 millimicrons (3) an aqueous 5 per cent titanium dioxide sol (obtained by pressing a gel through a nozzle at 80 ats.) is expanded at 420 DEG C. and 230 ats. (4) a 6 per cent aqueous alumina sol (obtained by peptizing a gel with formic acid) is expanded at 320 DEG C. and 150 ats. to give needle-shaped boemite rods 1-2 by 0.025-0.1 microns in size. Other suitable starting materials include sols of metal oxides and mixtures or compounds thereof with silica in water and/or organic liquids. Silica sols may be obtained by dialysis or electrodialysis of soluble silicates or treatment thereof with ion exchangers, by removal by cooling or precipitation of salts from the reaction product of waterglass and an acid, by hydrolysis of silica acid esters or by dissolving elementary silicon in ammoniacal or amine-containing liquids.  Gels may be pressed under high pressure through nozzles or slits and the resulting colloid mixed if desired with substances altering the pH, or with organic acids which alone are insufficient to cause peptization.  Metal oxide, e.g. alumina, sols produced by hydrolysing an alcoholate by electrolysis of salt solutions by dissolving metals in water or aqueous organic liquids, and by reaction of metal halide solutions with alkylene oxides ar ealso mentioned.  Specification 649,896 and U.S.A. Specification 2,589,705 are referred to.
