Fig. 16 shows a tuning fork oscillator 131 held above an insulating base 137 by a terminal post 136. Oscillations are detected by an electrode 134b sandwiched between electrets 132b, 133b and connected to post 135b. A similar block connected to post 135a is used to drive the oscillator. The electrets are spaced from the tines but may alternatively be bonded thereto Fig.2 (not shown). Fig. 10 shows a flat oscillator with outer limbs 91 which co-operate with driving electrodes 95, and a centre limb 92 co-operating with a sensing electrode 96. The electrodes are bonded to electrets 93, 94. The electrode 96 is 0.51 times as long as the limb to give low output voltages for second and third order spurious oscillations. The electrodes may be attached to an insulating plate (14), Fig.1 (not shown) or to the inside of an insulating case Figs.17-23 (not shown). Electrostatic shielding may be provided between drive and sensing electrodes. Various forms of reed and flat blade oscillators are described, with electrodes and electrets on one or both sides, and a flat plate oscillator (101), Figs. 12 and 13 (not shown) suspended by transverse wires (102).

In one embodiment, the degree of neutralization in step (a) is controlled so that the final composition has a pH of from 7À2 to 8À0. The hydroxyalkyl ester component of the interpolymer may be an ester of acrylic, methacrylic, ethacrylic, crotonic, maleic, fumaric or itaconic acid, and the acid component is preferably acrylic or methacrylic acid. The remaining component(s) may be selected from monomers such as alkyl (meth)- acrylates, vinyl aromatic hydrocarbons, olefins, unsaturated amides and nitriles, vinyl esters, vinyl chloride, methyl crotonate and allyl chloride. Neutralization of the interpolymer is suitably effected with ammonia or an amine. Aminoplast resins which are useful include condensation products of melamine, urea or acetoguanamine with formaldehyde or other aldehyde such as acetaldehyde, crotonaldehyde, acrolein, benzaldehyde or furfural; the alkylol groups of the resins may be etherified, if desired, e.g. with methanol or butanol. In coating applications, the compositions can be sprayed on to a substrate with a spray gun and cured by heating; examples of substrates are wood, paper and metal, e.g. primed or unprimed aluminium or steel. The preferred use is the coating of automobiles.

Abstract: 1480099 Decorative coated panels ABITIBI CORP 27 Dec 1974 [26 Dec 1973] 55931/74 Heading B2E [Also in Division B5] A panel having a surface pattern of ridges and walled recesses of varying heights and depths is provided with a pattern by applying a liquid pigmented coating over the surface, pressing a rotating resiliently-deformable roll against the moving surface so that there is no relative movement between roll and surface at the contact area and so that the roll contacts the higher ridges and recess walls and removes the coating therefrom, removing the picked-up coating from the roll, and at least partially curing or drying the remaining coating. The removal of the pigment takes place in graduated manner owing to decrease of contact pressure with depth. The panel may be an embossed or textured fibreboard, plywood or particle board, and is preferably a laminate which has been obtained by hot-pressing a wood-grain patterned paper on to a partially dewatered fibreboard and simultaneously embossing so that the paper pattern and the surface embossments are out of register; such panels are then oven-baked, cooled and rehumidified. After partial curing, the coated panel may be provided with a transparent topcoating and both coatings are then fully cured. Both coatings may be applied by roller or spray and cured by hot-air, and may comprise amine-modified aqueous acrylic emulsions. The pigmented coating may be transparent and is preferably applied by a soft-pile fabriccovered roller. The resilient roller may be associated with a sponge-surfaced washer roller and a doctor blade for removing the picked-up coating.
