Title: Improvements in or relating to the production of decorative and protective coatings
IPC: B05D5/06
Filed: 1953-01-23
Abstract: An article is provided with a decorative finish by applying thereto a base coating in the form of a pattern, and applying a continuous overlying or protective outer coating in wet condition to the base coating while the latter is still wet, the overlying coating having a predetermined controlled incompatibility with the base coating so that it is differentially repelled therefrom while still retaining its continuous protective relation.  An exemplary base coating comprises a pigment consisting of titanium dioxide, aluminium hydrate, lithopone, molybdated orange and lithol rubine mixed with a vehicle consisting of refined linseed oil, long oil alkyd resin, high boiling hydrocarbon thinners, and manganese lead and cobalt naphthenates to form a pink graining paste which was applied with a roller, and, while still wet, sprayed with a brown, synthetic enamel comprising yellow, red, black and white tinting enamels mixed with a medium to short soya bean oil resin resulting from reacting dicyclopentadiene with soya bean oil and adjusting to 70 per cent solids with mineral spirits, a condensation product of urea with formaldehyde alkylated with butanol and octyl alcohol, and naphtha. The tinting enamels comprised respectively tartrazine yellow pigment, lithol rubine, carbon black and zinc oxide in a mixture of the above dicyclopentadiene copolymer and naphtha.  The dicyclopentadiene copolymer may be used as the vehicle in the pink graining paste, and the desired degree of incompatibility with the above brown enamel secured by adding a suitable amount of a silicone oil to the paste.ALSO:<PICT:0734140/III/1> An article is provided with a decorative finish by applying thereto a base coating in the form of a pattern and applying a continuous overlying or protective outer coating in wet condition to the base coating while the latter is still wet, the overlying coating having a predetermined controlled incompatibility with the base coating so that it is differentially repelled there from while still maintaining its continuous protective relation.  The design of the base coating 11 is preferably of an open, discontinuous type, the overlying coating 12, which may be of a contrasting colour, being partially repelled away from the thicker portions of the design, so as to be thicker and have its surface raised in areas relatively free from the base coating.  The two layers may then be set or cured simultaneously. The design layer may be applied by printing, rotogravure, or silk screen, or by painting with a brush, and the outer layer may be sprayed on, printed or roll coated.  Suitable compositions for the two coatings are described (see Group IV (a)).

Title: Improvements in switch gear for electric transformers
IPC: H01H9/00
Filed: 1931-01-22
Abstract: 371,414. Snap-action switches; regulating-switches. JANSEN, B., 7, Brunnleite, Regensburg, Germany. Jan. 22, 1931, No. 2205. [Class 3S (v).] A transformer tapping switch has tapping contacts arranged about the circumference of a circle with the contacts which succeed each other in order of voltage disposed at the ends of the longest available chords, and has a double contact switch member which occupies a radial position for the normal connection of anv one of the contacts to the main and is moved for changing to the next voltage, first into register with the chord between the functioning contact and the selected contact and then into the radial position appropriate to the selected voltage. In one construction, the eight tapping points such as 1, 2 are mounted on a stand in the form of a regular octagon. The lead A to which the tapping points are adapted to be connected, is connected to a carrier C which carries the main contacts E1, E2 and auxiliary contacts F1, F2. The carrier C has a slot in each end which engages the base of the tapping points to serve as a guide and pivot. To change from tapping point 2 to tapping point 1 the arm B is rotated causing the carrier C to rotate first about the end in contact with the tapping point 2 and then to move across until the other end engages the tapping point 1. In this intermediate position the contact E2 has left the tapping point 2 but the contacts F1, F2 have separated due to the gear connection at their base, and two springs. Thus the contacts F1, F2 connect respectively with both tapping points 1, 2. Resistances G1, G2 reduce the short-circuit current. On continued movement of the arm B the contact E1 engages the tapping point 1 and the contact F2 leaves the point 2. A quick action is given to the arm B by the rotation of a spindle H which stretches a spring J until a stud N2 tilts an arm N3 to release a catch M, thus allowing the carrier C to move quickly. In a modification showing five tapping points, the carrier has a roller at each end travelling round a pentagonal orifice in a guide-plate.

Filed: 1937-01-26
Abstract: 489,611. Supplying fuel to aircraft engines. ELLOR, J. E. Jan. 26, 1937, No. 2293. [Class 69 (i)] [Also in Groups XVII and XXVIII] An aircraft fuel tank is divided into at least two unconnected compartments to each of which pressure air is independently admitted and from each of which an independent outflow pipe leads, and means are provided for opening an escape to atmosphere from each compartment when the fuel in it is exhausted, for example, when it is punctured by a bullet, so that air and fuel vapour is not forced from the tank to the pump. The tank shown is divided into four unconnected compartments A ... A<3> to which pressure air is supplied by forwardlydirected nozzles A<4>. In each compartment is a cylinder B, the space within which communicates with the compartment by upper and lower apertures B<1>, B<2>. The cylinders project below the bottom of the tank, and communicate with a common outlet pipe C through lightlyloaded valves (not shown). At the top of each cylinder is a spring-loaded valve D<3> which normally closes an air-escape to a rearwardlydirected nozzle D<5>. When the fuel in a compartment is exhausted, a float D slidable on a rod D<1> articulated to the valve stem rests on a flange E on the rod, and by its weight opens the valve. A filling-opening E, Fig. 4, is provided in the compartment A<1>, the other compartments being filled from this compartment by pipes E<5> extending from a tapered seating E<4> which is closed by a plug E<3> carried bv a stem E<2> on the closure-member E<1> of the filling-opening E, so isolating the compartments from one another. The pressure air may alternatively be supplied from a pump or other source, the pipes leading from such a common source to the compartments being relatively small so that release of pressure in one or more compartments will not appreciably affect the pressure in the others.
