Title: Improvements in and relating to apparatus for use in the carbonation of liquids
IPC: B01F3/04
Filed: 1940-04-30
Abstract: 538,937. Closures for bottles ; aerating. SUSSMANN, M. April 30, 1940, No. 7716. [Class 125 (iii)] A combined closure and relief valve for use in the introduction of carbonic acid gas into liquids, has a hollow stopper body 10 adapted to screw into the bottle neck, and a mushroom form valve member 14 by means of which the gas is admitted when the valve of the gas container is opened. The gas passes through the central bore 13 and the radial bores 23, then passes the rubber sleeve 25 which forms a non-return valve. The head 14 is seated on a rubber diaphragm 15 which itself rests on a shoulder 16 in the closure body 10. The central hole in the diaphragm 15 is rather larger than the stem of the mushroom valve 14, and close to this hole the diaphragm rests on a spring-pressed sleeve 32 with a number of relief holes 33 arranged opposite holes 34 in the body 10. An annular channel 17 on the under side of the head 14 is connected by passages 17a to the gas supply channels. The stoppered bottle is inverted while gas is supplied and forced past the valve 25 while the pressure is communicated to the channel 17. Normally this pressure is balanced by the pressures of the atmosphere and spring 31 on the underside of the diaphragm. When the gas pressure in the bottle exceeds this valve the centre of the diaphragm is moved away from the head 14 to connect the space 17 to the atmosphere. The stem of the valve 14 may be provided with an extension to lead the gas to the bottom of the container in order to avoid the container.

Title: Improvements in and relating to surface coatings
Inventor: CHATFIELD HERBERT WALTER
IPC: B05D7/26
Filed: 1958-03-12
Abstract: A lacquer comprising an unsaturated polyester and an ethylenically unsaturated monomer is applied to a surface to be coated, and a protective coating of a wax or fat in solution in a volatile solvent is applied over the lacquer coat within a period of about 2 hours after the application of the lacquer.  The term "wax or fat" includes substances of similar physical characteristics, as well as greases; examples are paraffin, ceresin, montan, carnauba and ozokerite waxes, beeswax and lanolin, and these may be dissolved in a saturated aromatic or aliphatic hydrocarbon or a halogen derivative thereof. After the protective coating has been applied and the lacquer coating has been cured, the former may be removed and the latter then polished.  In examples, an unsaturated polyester is prepared from maleic anhydride, phthalic anhydride and propylene glycol and is mixed with styrene monomer with hydroquinone as a stabilizer.  For use, the resulting solution is mixed with solutions of cobalt naphthenate and methyl ethyl ketone peroxide and sprayed on a suitable surface.  After a short interval, a solution of paraffin wax in benzene or of lanolin in a saturated hydrocarbon solvent are sprayed on the coating thus formed.  After 12 hours, the wax is removed and the lacquer surface, which is hard and tack-free is polished.

Title: Improvements relating to preventing the attack of solutions containing halides on iron and iron alloys
IPC: C23C10/26
Filed: 1935-03-15
Abstract: Articles of iron and iron alloys such as shipplates, pipes, and parts of pumps and containers are protected against attack by solutions containing halides, for instance sea water, or emulsions of oil in water containing halides, by first coating with a layer of an iron-antimony alloy rich in iron and then with an iron-antimony alloy rich in antimony or pure antimony or both. The first coating may comprise the alloy Fe3Sb2 and the second FeSb; further the protective layers may be applied after heating the surface to be protected above the melting point of the materials forming the layer, care being taken to prevent the formation of an oxide coating on the surface to be protected. Moreover, the protective layers may be applied by electrodeposition or by a metalspraying process.  When antimony forms the final coating it may be deposited from the vapour phase.

Patent GB-541835-A (GB)
Title: Improvements in reinforced concrete constructions, and in the manufacture thereof
Inventor: ABELES PAUL WILLIAM
IPC: B28B23/06
Filed: 1940-05-06
Abstract: 541,835. Reinforced concrete. ABELES, P. W. May 6, 1940, No. 8080. [Class 20 (iv)] A reinforced concrete beam 1 is provided with longitudinal members 3 of high tensile steel, and tensioned thin wires 2, both in the tensile zone. Additional members 4 may be provided in the compression zone to take up the counter-bending moment produced by the pre-tensioned members 2. If the beam is to be subjected to bending in more than one direction, additional members 2, 3 may be provided accordingly, so that the bending moments produced by the wires 2 are balanced and only pressure stresses are set up in the concrete. The tension in the wires is such that when calculated as a homogeneous material the resultant tensile stress when under load is in excess of the tensile strength of the concrete. Fig. 11, e and f shows the deflection of the beam before and after loading. To apply tension to the wires, two or more beams 10 are arranged on either side of a spacing member 13 either in a mould or in situ, the wires 12 passing over a spacer 14 and an expansion screw 16. Additional reinforcing bars 15 correspond to the members 3, 4. Alternatively, the wires may be tensioned by passing them round a bar which is then twisted and serves as an anchorage for the tensioned wires. In another method a screw may be partly embedded in the concrete and may carry a reel around which the wire is wound. Tension is applied by rotating the reel to move it along the screw. If tension is applied before setting of the concrete, the projecting ends of the wires are cut; otherwise anchoring devices may be provided in cavities at the ends of the structure. A single continuous length of wire may be looped over a bar at one end of the structure, and tension applied only at one end, or a continuous length may pass in succession through the moulds for a number of beams arranged adjacently, tension being applied only at the ends. If tension is applied after setting of the concrete, bonding of the wires in the concrete is prevented by coating them with asphalt or bitumen, arranging them within pipes, or winding paper tape over them. Specifications 338,864 and 338,934, [both in Class 20 (iv)], are referred to.
