Title: Improvements in or relating to alkyd resins
IPC: C09D167/08
Filed: 1954-02-16
Abstract: An alkyd resin is made by reacting, e.g. at 100 DEG  to 550 DEG  F., a mixture of a polycarboxylic acid, a polyhydric alcohol, an unsaturated monobasic aliphatic acid and a hydrolysable polysiloxane, the monobasic acid being interpolymerized before, during or after the reaction, with a polymerizable olefinic monomer.  Preferably the monobasic acid is a drying, semi-drying or non-drying oil fatty acid and the monomer is styrene or a nuclear alkyl or halogen substituted styrene.  The monobasic acid may be partially polymerized prior to use and may be used in the form of a partial ester thereof with the polyhydric alcohol. Reactants specified are monomers-styrene, vinyl and vinylidene chlorides, vinyl esters, esters of acrylic and methacrylic acids, ethylene, butadiene and cyclopentadiene; unsaturated monobasic acids-acrylic, methacrylic, vinyl-acetic, hydrosorbic, decenoic, undecylenic and sorbic acids; dehydrated castor, linseed, soya bean and tung oil fatty acids, rosin acids and tall oil acids; polyhydric alcohols-ethylene, diethylene, propylene and trimethylene glycols, glycerol, trimethylol-propane, pentaerythritol, polyallyl alcohol, sorbitol and mannitol; polycarboxylic acids-maleic, phthalic, tetrahydrophthalic and tetrachlorophthalic acids or anhydrides; citric, tartaric, fumaric, isophthalic, terephthalic, adipic and sebacic acids; polysiloxanes-dimethyltriphenyltrimethoxytri -, diethoxytetramethyldi -, diethoxyhexamethyltri -, diethoxyoctamethyltetra -, diethoxy decamethylpenta -, diethoxydodecamethylhexa-, tetraethoxydimethyldi -, dimethyltriphenyltrichlorotri - and trimethyltriphenyldichlorotrisiloxanes.  The interpolymerization may be effected in an inert atmosphere in the presence or absence of solvents and/or diluents and using a catalyst such as hydrogen, benzoyl, t-butyl hydro -, di - t - butyl or acetyl peroxide, stannic chloride, boron trifluoride or a mixture of dodecyl mercaptan and benzoyl peroxide (redox catalyst); polymerization controlling agents such as fuller's earth, sulphur and sulphur dioxide may be added. The monomer is preferably used in amount of 5 to 75 per cent by weight to 95 to 25 per cent of the unsaturated acid.  The products, which are soluble, e.g. in mineral spirits or xylol, find use as resinous components of paints, varnishes and baking enamels. Examples are given.

Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1953-07-09
Abstract: <PICT:0769515/III/1> In the production of hydrogen peroxide from an alkyl anthraquinone by successive reduction and oxidation, a solution of the alkyl anthraquinone is substantially saturated with hydrogen, the hydrogen saturated solution is partially reduced in the presence of particle form hydrogenation catalyst, at least part of the partially reduced solution is oxidized by contact with a free oxygen-bearing gas, and hydrogen peroxide is recovered from the oxidized solution.  8-15 per cent solution of an alkyl anthraquinone, e.g. 2 - isopropyl, 2 - tert - butyl, tetramethylene, 2 - methyl, or 2 - ethyl anthraquinone, in solvents comprising benzene or alkylated benzenes, or in a mixture of light oils, e.g. a mixture of tetralin and methyl cyclohexanol, may be used.  Hydrogen is compressed, e.g. to 250-750 psia and passed through 11 into saturator 12, where it is dissolved in a mixture of recycled partially reduced anthraquinone solution from 13 and recycled oxidized solution from 14 in a ratio say 5 to 0.8:1.  The hydrogen-saturated solution passes to reducer 16, preferably containing a fixed bed of, e.g. Raney nickel, or palladium or platinum on alumina, to effect 50-75 per cent reduction at 30-80 DEG C.  The major portion of the reduced solution is recycled to the saturator through 17, 13 and the remainder passes through further reducer 20 to oxidizer 22 where it is contacted with air entering at 25.  The oxidation may be as described in Specification 768,675 by concurrent or countercurrent contact at 30-80 DEG C. and 15-300 psia. in a tower packed with inert solid. The oxidized solution passes to water extraction system 27, with water entering at 30.  Strong hydrogen peroxide is withdrawn at 31 and separted intermediate solution is recycled through 14.  The extraction may be in 3 stages with concentration by vacuum distillation.  Extraction may be effected by distillation in the presence of steam at 70-105 DEG C. and 5-65 mm. Hg. as described in Specification 769,514.  Compression of the hydrogen to above 750 psia renders the recycling of reduced and oxidized solution unnecessary.

Abstract: 1,249,733. Once-through steam generators; expansion joints for furnace walls. BABCOCK & WILCOX CO. 31 Jan., 1969 [1 Feb., 1968], No. 5324/69. Headings F4A and F4B. In a vapour generator including a gas pass having two walls meeting at a corner, wrapper means mounted on the outside of the walls define a gas-tight space, the boundaries of the wrapper means including upper and lower portions extending laterally from the walls and each having an expansion joint provided by an arcuate slot extending around the corner and closed by a flexible cover. A forced-flow oncethrough steam generator comprises four upright tube walls 14, 16, 18, 20, Fig. 2. A windbox (46), Fig. 1 (not shown), enclosing cyclone furnaces (44) disposed on opposite walls 18, 20, enclosures (68, 70) through which recycled flue gas is passed into upper and lower portions of the furnace chamber, and a jacket (78) enclosing fluid mixing headers (76) are all of the form typified by the enclosure 90 shown in Fig. 2. The enclosure 90 comprises a wrapper 92 having top and bottom plates 94, 96 connected by an annular side-plate 95. Each plate 94, 96 has a flange 104, Figs. 3 and 4, welded at 98 to a tiebar 105 mounted on each wall 14, 16, 18, 20. To allow for the fact that thermal expansion of the furnace chamber is greatest at each corner 19, the flanges 104 are spaced from the walls near each corner 19. A flange 106 at each corner 19 is also spaced from the corner. An extensionplate 108, Figs. 3 and 5, bent around the corner 19, is used to connect the flange 106 and the adjacent parts of the flanges 104 to the walls. Thermal expansion is also allowed for by providing each plate 94, 96 with an arcuate slot 124 at each corner 19, the slot being covered by an expansible and contractible arcuate plate 126 of pleated or corrugated cross-section, which is welded along its longer side to the plate. Each end of the arcuate plate 126 is covered by a plate 130 welded thereto and to the plate 94 or 96. The enclosure 90 is braced by truss assemblies 134, 136, Fig. 2, each truss assembly being made up of four interconnected trusses 140, Fig. 8. Each truss 140 comprises an inner chord 142 and an outer chord 144, the chords 144 of the upper and lower trusses being interconnected by vertical posts 152. Each inner chord 142 is rigidly connected at mid-length to the associated wall 14, 16, 18 or 20 and connected near its ends by tie clips 158 to a bar 154 which is welded to the wall. The tie clips 158 permit relative thermal expansion between the wall and the inner chord. Cross-members 146 interconnect the inner chords 142 and outer chords 144. Each truss 140 is connected to the neighbouring truss by link assemblies 160A, 160B. Alternatively, as shown in Fig. 9, adjoining bars 154 are interconnected by plates 180.

Title: Improvements relating to Registering or Counting Apparatus for Machines.
Inventor: JOHANSON GUSTAF EMANUEL
IPC: G07C3/04
Filed: 1916-04-12
Abstract: 100,279. Johanson, G. E. April 13, 1915, [Convention date]. Counters affording several rates of actuation; transmitting actuation to counters. - Apparatus for registering the time of working of a machine and the amount of the workmen's wages comprises means, such as a counter, whereby the agreed maximum wages are indicated, together with any additional wages which may be shown on the same or a separate register. The apparatus is described as applied to a saw-mill through which three different widths of material are passed, one or more rollers 2, 3, being engaged thereby. The roller 2 drives a shaft 8 through gearing 12, 15, and the other two rollers drive a sleeve 20 through spur and ratchet gearing 13, 16, 21, 22 and 14, 17, 23, 24. Operation of the counter is effected by a device comprising a clock or like shaft 25, Fig. 3, driving through worm gearing, an internally-toothed wheel 27, which is loose on a shaft 28 adapted to be rotated by the shaft 8 through bevel and spur gearing 40, 41, 42. A planet gear 30 carried by a disk 32 engages the exterior teeth of the wheel 27 and also a wheel 31 secured to the shaft 28. A pawl 33 on the disk 32 is adapted to rotate a disk 35 through ratchet-wheel 34, the disk 35 carrying the pinion of an epicyclic train 38, 36, 37 similar to the first. When the shaft 28 is stationary, the pawl 33 moves inoperatively over the wheel 34; but when the shaft 28 is in motion, the wheel 37 is caused to move at the same rate as the wheel 27, and the movement of the sleeve 39 of the wheel 37 may be communicated to a counter showing the time of working of the machine. Motion of this sleeve 20 is conveyed through spur-and-worm gearing to an epicyclic train 49, 48, 50 carried by the sleeve 39 and a sleeve 51, which may be employed to drive a registering-device showing the total wages. A lost-motion device may be interposed between the driving and registering mechanisms to delay increased registration until a certain minimum wage has been worked-off.
