Title: Method of distributing a liquid onto a sheet
IPC: B05B15/68
Filed: 1965-11-17
Abstract: Coating apparatus comprises means for continuously advancing in a horizontal or slightly inclined plane a sheet to be coated with liquid, a nozzle capable of spraying the liquid on to the sheet, means for moving the nozzle above and laterally across the sheet in a reciprocating motion at right angles to the direction of advancement of the sheet and is characterised in that it has means for deflecting the nozzle to either side of the direction of advancement of the sheet in response to the lateral position of the reciprocating nozzle with respect to the sheet by means of a guiding device for the nozzle.  In one embodiment (not shown) the nozzle is held in a null position by springs, is rotatable in a vertical, horizontal or inclined plane about a pivot and is deflected at the ends of its reciprocating travel by contacting stationary rods or plates.  In the embodiment shown a cam 21 in contact with a guiding surface 30a, 30. 30b is used to pivot the nozzle 25 inwardly at the ends of its reciprocating motion. Various cam guiding surfaces give even or pattern distribution of the coating liquid on the sheet.  In another embodiment the nozzle is pivoted by a chain and sprocket mechanism.

The colourdeveloper polymer is mixed with other materials, e.g. solvents, binders, inorganic pigments and carboxylic acids or their metallic salts as stabilizers, and coated on supports, e.g. sheets of paper. Coloured images are obtained by contacting the sheets coated with the colour-developer composition with sheets coated with microcapsules of colour-former and applying pressure or heat. In examples polymers are obtained by condensing formaldehyde with salicylic acid and with 2,6-dihydroxybenzoic acid, the condensates are reacted with sodium hydroxide and potassium hydroxide and the sodium and potassium salts so obtained are reacted with zinc sulphate, tin sulphate, nickel sulphate, copper sulphate, zinc chloride, tin chloride, manganese chloride, aluminium sulphate and lead sulphate to obtain the polymers of the invention; compositions are prepared from these polymers and coated on paper to form colour-developer sheets, the other materials in the compositions being water, ethanol, toluene, petroleum naphtha, butyl acetate, methoxy ethanol and benzene as solvents, gum arabic, wheat starch, sodium carboxymethyl cellulose, polyvinyl alcohol, ethyl cellulose, gelatine, styrene-butadiene copolymers and nitrocellulose as binders, titanium dioxide, aluminium silicate, magnesium carbonate, kaolin, zeolite, talc, bentonite and zinc silicate as pigments and caprylic acid, sodium oleate, chlorostearic acid, zinc stearate, sodium salicylate, stearic acid, benzoic acid, lauric acid, sodium behenate, salicylic acid, oleic acid, dodecan-1,12-dicarboxylic acid, p-chloro-benzoic acid and p-isopropyl-benzoic acid as stabilizers; colour is formed by placing the developer sheets on paper coated with microcapsules of the colour-formers Crystal Violet Lactone and 3-dibenzylamino-7-diethylamino, fluorane and applying pressure.

Abstract: 1,176,508. Valves. CLARK EQUIPMENT CO. 8 Nov., 1967 [30 Dec., 1966], No. 50849/67. Heading F2V. A valve has a pair of pistons 34, 50 normally urged to the position shown by springs 72, 68 so that all the fluid admitted through inlet 14 passes to main outlet 22 via orifices 42 in piston 34, slots 58 in piston 50 and annular chamber 26. Should the pressure in an hydraulic load-lifting ram 78 (Fig. 2, not shown) rise above a predetermined limit, piston 50 is moved to the left against the action of spring 68 to disengage piston 34, whereby the pressure drop across orifices 42 causes piston 34 to follow piston 50 so aligning tapered parts 44 with annular chamber 32 connected to reservoir (82) by by-pass outlet 28.

The vibrations of an electrically conductive object, e.g. a rotating shaft, are detected by a coil positioned adjacent the shaft, which is connected to an oscillator whose output is amplitude or frequency modulated in dependence on the distance between the object and coil. The coil is itself vibrated for calibration purposes and the output signal, when the calibration vibration signal has been removed, is representative of the vibrations of the shaft alone. The pick-up coil 105 Fig. 3 is wound on a soft iron core 100 located in the pick-up housing 78 at one end of a shaft 36 whose other end is attached to a brimorph crystal vibrator 34 Fig. 4, e.g. a Piezo-electric vibrator comprising a pair of Piezo-electric plates energized by a stabilized oscillator 126. The coil 105, energized by a carrier frequency oscillator 120 Fig. 4, amplitude modulates the input to a pre-amplifier detector 124. The demodulated output signal, representative of the vibrations of the coil and the test shaft 28, is fed via a high pass filter 140 to amplifier 142 having a feedback network including an automatic gain control circuit 150. The output from amplifier 142 is fed via a band pass filter 146 tuned to the calibration vibration frequency of oscillator 126, to a rectifier network 144 whose output signal is therefore indicative of the measurement sensitivity and is used to adjust the circuit 150 whereby the gain of amplifier 142 is maintained at a level at which the signals from network 144 correspond to the standardized axial vibrations of the coil. Amplifier 142 is also connected to a differential amplifier 154 in opposition to the signal from filter 146 to produce a measurement signal free of calibration vibration components.
