Title: Improvements in or relating to the Production of Thermosetting Coatings
Inventor: SCHAERER ANDRE
IPC: B05D1/00
Filed: 1967-05-26
Abstract: 1,187,452. Thermosetting coating. A. SCHAERER. 26 May, 1967 [2 June, 1966], No. 24735/67. Headings B2E and B2K. Thermosetting coatings or films on rigid or flexible flat articles are produced by continuously feeding a thermosetting resin to the gap between two counter rotating rolls heated to a temperature sufficient to cause the resin to become molten, maintaining molten resin in contact with the rollers at a temperature such as to increase the viscosity of the resin by partial curing thereof, transferring the partially cured resin from one of the rollers directly or by the intermediary of an offset roll onto the article, and further curing the coating or film applied to the article. The articles may be wood chip panels, wood fibre boards, ply wood sheets, wood panels, metal sheets, non-woven fabrics, pre-impregnated papers, heat-resistant plastics sheets. Thermosetting resins mentioned are unsaturated polyester, alkyd, epoxy resins. The coating may be embossed. In an embodiment an unsaturated polyester resin resulting from condensation of phthalic or isophthalic acid with ethylene glycol is melted on a set of mixing rolls and then mixed with N-vinyl carbazole or prepolymerised diallyl phthalate. Benzoyl peroxide or dicumyl peroxide, hydroquinone inhibitor are added, followed by fillers and pigments such as wood flour, calcium carbonate, titanium dioxide. The mixture is allowed to cool and then ground to form a powder. The resulting granular thermosetting resin 1 is fed into the gap 2 of two oppositely rotating rolls 3 and 4 which are heated to 120‹ Centigrade. The resin is melted in the gap and during the retention time in the gap it is subjected to partial curing. A film 5 adhering to the roll 4 is transferred to the carrier 6. The film is then heated at 200‹C. in a high frequency field or by radiant heat and compacted by cooled or heated pressure rolls, and matt finished or polished.

The indicator may then be backed with a sheet of vulcanized fibre 7, and mounted between two sheets of fibre-glass 9 and 10 impregnated with polythene or other plastic, one sheet being provided with apertures 11 and 12 to enable connections to be made to the contacts on the back of the indicator and the other sheet being provided with a window 13, covered if desired with nylon mesh 8, to allow the atmosphere to come into contact with the front surface of the indicator 1. The complete indicator may then be mounted in an aperture in the wall of a cocoon protecting apparatus whilst in storage. Measuring-apparatus, Fig. 4.-The unbalance voltage of a bridge circuit, in which the humidity indicator is connected at TP in series with R5 across one of the arms R4, is amplified in transistor amplifier SC2 and SC3, rectified, and indicated on meter M. The bridge is energized via transformer T1, whose secondary forms two of the arms of the bridge, from an oscillator formed by transistor SC 1 and the primary of transformer T1. Resistor VR1 provides an initial bridge balance with the humidity indicator TP disconnected. Resistors R5 and R12 are included to vary the scale shape, and resistor R13 is provided to connect in place of the humidity indicator at TP in order to standardize the circuit by adjusting VR3 to obtain a predetermined deflection on meter M.

Title: Stable chloroprene polymer dispersions

Filed: 1973-05-29
Abstract: 1419145 Polymerizing chloroprene MONSANTO CO 29 May 1973 [30 May 1972] 25554/73 Heading C3P Chloroprene is polymerized in aqueous dispersion to obtain a product of narrow particle size distribution by (1) forming a polymerization medium comprising water, a redox system containing sulphate and sulphite ions and a metal activator and optionally an emulsifier, (2) allowing these to interact, (3) adding monomer, (4) introducing additional sulphate ions together with emulsifier where none was added at (1) or optionally with further emulsifier and (5) maintaining polymerization conditions to polymerize at least a major proportion of monomer. The particle sizes fall in the range 0À15-2 microns. In one example two dispersions containing different sized particles, one being 0-2 micron, the other 0À6 micron, are mixed. The redox sulphate radicals may be obtained by oxidation of sulphite radicals using a peroxide or as in the examples by using a persulphate/bisulphite initiator. Sodium lauryl sulphate is the preferred emulsifier. In one example acrylonitrile is copolymerized with the chloroprene.

Title: Improvements relating to circuit arrangements for a.c. actuated relays
Inventor: HADICK WILHELM
IPC: H03K17/64
Filed: 1961-07-14
Abstract: 981,881. Transistor relay circuits. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. July 14, 1961, No. 25630/61. Heading H3T. A circuit for actuating a D.C. relay 12 when the amplitude of an A.C. quantity u exceeds a predetermined value comprises a converter stage 1 to which the A.C. quantity is applied and the output of which consists of uni-directional rectangular pulses of constant amplitude when the predetermined value is exceeded, a generator stage 2 in which the output of the converter stage is changed into a continuous alternating rectangular waveform, and rectifying means 9 in which the continuous alternating waveform is rectified to a unidirectional quantity of constant amplitude before being applied to the relay. The converter stage 1 comprises a bi-stable circuit which gives a zero output if the amplitude of the A.C. quantity u is below the response value of the stage, but as soon as the input exceeds this value a signal of constant amplitude at the output until the amplitude falls below the cut-off value. The generator stage 2, Fig. 2, includes a Wheatstone bridge comprised of resistors 3, 4, 5, 6 and transistor 7, the latter forming a fourth arm of the bridge and acting as a variable impedance dependent upon the presence or absence of the output pulses from the converter stage at its input. Thus when the transistor is rendered conducting, current flows from b to a through resistor 6 but when there is no output from the converter stage current flows from a to b. The values of the resistors are adjusted so that the two currents are of the same magnitude and in order that the direct current flowing through resistor 6, when the amplitude of the A.C. quantity u does not exceed the response value of the converter stage, does not release the relay 12 a transformer 8 is provided. The output of this transformer is rectified by bridge 9 and then passed to power transistor 11 causing the relay 12 to be actuated. It may be desirable when the required maximum time lag due to the circuit is less then the period of the A.C. quantity u to rectify the input signal before passing it into the converter stage 1, so that a pulse with double the frequency of the A.C. quantity u is obtained. Alternatively two opposite bistable stages in the converter stage 1 may be used to achieve the same result, one operating during the positive half cycle and the other during the negative half cycle.

Title: Improvements in screw operated presses
IPC: B30B1/22
Filed: 1944-12-22
Abstract: 598,359. Screw presses. HORDERN, MASON, & EDWARDS, Ltd., EDWARDS, W. G., DEYKIN, R. F., and WILSON, G. S. Dec. 22, 1944, No. 25743. [Class 87 (ii)] A screw press, of the kind wherein the screw 11 is driven by driving discs 17, 18 forming part of a sliding unit 25, has a compressed air piston- and-cylinder arrangement 36, 37 which acts, through a lever system 34, 31, 30, 26, to slide the discs 17, 18 into the downward driving position. When the ram 13 reaches the end of its downward stroke, a valve 48, is operated, by hand or by a pivoted abutment 54 on the ram, to cut off the compressed air supply and open the cylinder to exhaust. The abutment 54 operates the valve by engaging a roller 58 connected, through a linkage, with the handle of the valve. After the air is cut off, the turning moment of a braking arm 41 and a weight 39 causes the lever system to rock and move the discs 17, 18 into the upward driving position. When the ram reaches its upper limit, the driving wheel 12 engages and moves the braking arm 41, the speed of the wheel 12 being thus reduced and the lever system rocked to move the discs into a neutral position. The cylinder 37 is then opened to compressed air, by hand, to start the ram again on its downward stroke. The abutment 54 is pivoted to prevent it fouling the roller 58 on the up stroke of the ram. Screw means operated by a hand wheel 9 may be provided to alter the angle between bars 40 and lever 26.
