Title: Production of heat resistant coatings of metal on another metal
IPC: C23C4/08
Filed: 1945-07-05
Abstract: Metal surfaces, e.g. of iron or steel, are given a heat resistant coating by spraying in powder form an alloy or mixture of nickel, chromium and aluminium or one of said metals and an alloy of the other two, with or without iron or steel, by means of a spray gun, the powder as it issues from the gun being heated to a temperature sufficient to produce fusion or sintering of the particles to render them adherent to the base metal.  Aluminium may be present in the powder up to 50 per cent.  The coated base may be heated to produce alloying of the coating and base metal, and a pre-coating of sprayed aluminium may be applied.  To encourage the deposited metal to form a protective oxide coating the base article to be coated may be heat-treated.  Specification 551,689 is referred to.

IPC: G01S7/06
Filed: 1942-12-04
Abstract: 582,493. Transmission line switching systems. COCKCROFT, J. D., ASHMEAD, J., EASTWOOD, W. S., OXFORD, A. J. H., THOMSON, A. F. H., and' BUTEMAN, W. A. S. Dec. 4, 1942, No. 17309. [Class 40 (iv)] [Also in Groups XXXV and XL] A system for determining the range and direction in azimuth of a reflecting body, such as a ship or low-flying aircraft, comprises an aerial array for transmitting a pulse-modulated signal and an aerial array for receiving the reflected signal, both arrays being rotatable about a common vertical axis, a phasing switch being provided for varying the directivity of the receiving array. The inner staclis of aerials are connected through feed-lines 81, 82, Fig. 8, of electrical length l+x to a transmission line 80 of length x, where x is the desired angle of tilt. Similarly the outer stacks of aerials are connected by feed-lines 85, 86 of electrical length l to a transmission line 84 of length 3x. Quarter-wave transmission lines 87, 88, 90, 91, 93 ... 96 and 98, 99 are connected as shown, lines 96, 99 being terminated by diodes 97, 100, which are made conducting in turn by means not shown. Where diode 97 conducts, the three-quarter length lines 96, 95, 87 ; 96, 95, 88 ; and 96, 95, 93 are in effect short-circuited and present a large impedance, so that energy from the left-hand pair of aerials passes through phasing sections 80, 84 and lines 90, 91, 94 to the common feed line 83, the effective lengths of the aerial feeders being l + 3x, l + 2x, l + x, and l respectively. When the diode 100 conducts, complementary changes occur, the effective lengths of the aerial feeders being then l, l+x, l+2x, l+3x respectively. The directivity of the aerial system thus varies synchronously with the energization of the diodes 97, 100. Specification 582,521, [Group XL], is referred to.

Patent GB-1100531-A (GB)
Title: Fire-resistant plastics
Inventor: EVANS REGINALD WARNFORD
IPC: E04C2/34
Filed: 1963-05-02
Abstract: The fire resistance of a solid body of synthetic resin formed by the polymerization of an unsaturated resin in a non-aqueous liquid condition is increased by the incorporation of dry sodium bicarbonate or borax in the resin before it hardens.  The preferred resin is an unsaturated polyester resin.  In an example are used methyl ethyl ketone peroxide as catalyst and cobalt naphthenate as accelerator, sodium bicarbonate being sprinkled over the resin while still soft and rolled in.  Alternatively the bicarbonate may be mixed with the liquid resin before the catalyst and accelerator are introduced. In another example the bicarbonate is mixed with a powdered filler, e.g. calcium carbonate, and the mixture stirred into the resin before placing in a mould.
