Title: Apparatus for fabricating wood structures
IPC: B27F7/15
Filed: 1972-01-13
Abstract: 1335802 Releasable fastenings W G MOEHLENPAH 13 Jan 1972 [13 Jan 1971] 1754/72 Heading E2B [Also in Division B4] In apparatus for fabricating wood structures (see Division B4-5) stands 9 are mounted for movement on a track 35. Each stand comprises a head or table 11 rotatable about the upper end of a post 37. A screw clamp 47 enables the table 11 to be secured in a selected rotary position. Work holders 13 are mounted on base plates 49 secured to arms 51, 53 slidable on the table 11. A clamping bar 57 can be urged by an eccentric cam 63, pivotally secured to a vertical rod 65, into clamping engagement with the arms 51, 53 so as to fix the work holders 13 in selected relative positions. Each work holder is pivotable relative to the associated base plate about axis Y-Y, and a cam clamp 81 is provided for clamping the work holder in a selected position. An eccentric 103 (Figs. 7 and 8) pivotally mounted on a frame secured to the base 33 of a stand 9 is rotatable by an overcentre linkage 111-121 to a position in which the surface 107 of the eccentric frictionally engages the outer surface of a rail 89 of the track 35 and a lug 109 secured to the eccentric engages the lower surface of the rail 89 to clamp the latter between the lug 109 and the base 33. A pair of flange members 99 (Fig. 5) engage the other rail 91. This arrangement for securing the stand to the track permits easy removal of the stand when the linkage and eccentric are moved to the inoperative position (Fig. 8).

Title: Improvements in and relating to moulded articles from thermoplastic resins
IPC: B05D5/12
Filed: 1952-01-22
Abstract: A moulded article having a surface free of any tendency to accumulate charges of static electricity is made by using a mould having a surface coated with an antistatic compound selected from the following organic salts:-(1) octadecyl disodium sulphosuccinamate (2) octadecyl guanidinium (or amine) N-octadecylcarbamate (3) stearamido propyl dimethyl hydroxyethyl ammonium chloride (4) diethylcyclohexylamine stearyl (or cetyl) sulphate.  (5) Trimethyl stearyl ammonium bromide.  (6) Amylamine p-toluene sulphonate.  (7) Organic amine salts obtained by reaction of certain specified furfuryloxy or tetrahydrofurfuryloxy aliphatic acids with a base which is ammonia or a primary secondary, tertiary or quaternary organic base; e.g. furfuryloxy acetic acid oleyl amine salt, 5-methyltetrahydrofurfuryloxy acetic acid methylamine salt, and tetrahydrofurfuryloxy acetic acid dimethyl cyclohexylamine salt.  The elimination of the static charge on the moulded article means that less dust collects on the article, and in addition the surface resistance of the moulded article to abrasion is increased, the tendency for plasticiser migration is decreased, and the salt can be employed as or in place of the usual mould release agent.  In an example, a solution of salt No. 1 (above) is applied by a spray gun to the mould cavity, and the mould is re-sprayed after the moulding of every fourth article.  Alternatively, the material may be brushed on to the mould.  The thermoplastic materials used in moulding may be polystyrene, P.V.C., methyl methaclylate polymer, polyamides and cellulose acetate.  The articles made may be tiles, lamp shades and clock and radio cases.

Title: Manufacture of monodiazo-compounds of 1 : 4-diamino-anthraquinone-mono- or disulphonic acids
IPC: C07C245/20
Filed: 1927-01-24
Abstract: 264,879. I. G. Farbenindustrie Akt.- Ges. Jan. 25, 1926, [Convention date]. 1-Amino-4-diazoanthraquinone mono- and disulphonic-acids are obtained by diazotizing the corresponding 1 : 4-diaminoanthraquinone sulphonic acids. The mono-diazo compound is obtained even with an excess of nitrite. Dyestuffs of the "Alizarine direct blue A " class can be obtained bv replacing the diazo group by halogen by a Sandmever process and reacting with an arylamine. Thus 1: 4-diaminoanthraquinone-2 : 6-disulphonic acid yields 1- amino-4-arylaminoanthraquinone-2 : 6-disulphonic acid. According to an example sodium 1: 4-diaminoanthraquinone-2 : 6-disulphonate is diazotized with sodium nitrite in dilute sulphuric acid and the mono-diazo compound salted out; the monosulphonic acid yields an insoluble monodiazo compound. Derivatives of 1: 4-diaminoanthraquinone-2-sulphonic acid such as the 6- or 7-substitution products are also referred to as parent materials. 1: 4-Diaminoanthraquinone-2 : 6- and 2 : 7-disulphonic acids are prepared by sulphonating 1- aminoanthraquinone-6- or 7-sulphonic acid, treating the product with bromide and replacing the bromine in the resulting monobromo derivative by an amino group.

IPC: C01C1/242
Filed: 1958-01-22
Abstract: <PICT:0865676/III/1> In the removal of ammonia from coal gas by washing with sulphuric acid and crystallising the resulting ammonium sulphate by vacuum evaporation, the gas is heated to a temperature of at least 48 DEG C. by heat exchange with hot flushing liquor from the coal gas collecting main.  As shown, gas, after passage through a primary cooler and a gas exhauster, passes through a line 1 at a temperature of 31 DEG C. into a direct heat exchanger 2 and an indirect heat exchanger 4, which heat exchangers are fed in succession with hot flushing liquor, e.g. at a temperature of 81 DEG C., through a line 3.  A mixture of steam and ammonia, e.g. at a temperature of 98 DEG C., is introduced into the gas via line 10 at a point between heat exchangers 2 and 4.  The gas, heated to a temperature of e.g. 52 DEG C., is scrubbed in a spray washer 9 with a sulphuric acid-ammonium sulphate solution which is circulated between the spray washer and a vacuum crystalliser 17 of known type.

Abstract: 1527922 Transverse-flow fans and pumps NISSAN MOTOR CO Ltd 21 Jan 1976 [28 Jan 1975] 2284/76 Heading F1C [Also in Division F4] Apparatus for accomplishing simultaneous mass transfer of a fluid and heat exchange between the same fluid and another fluid comprises an impeller which incorporates heat pipes of airfoil-like profile. The apparatus may be a fan blower, Figs 1 and 2, or a rotary pump, Fig. 5. As shown in Figs. 1 and 2, heat pipes 22 extend between support plates 24, 26 and through apertures in a solid cylinder 28, Fig. 1, to form an assembly which is rotatable in a housing 14 about an axis 20 by a motor 32. On rotation of the assembly, the heat pipes impel fluids F 1  and F2 and also effect heat exchange therebetween. The fluids are kept separate by the solid cylinder 28 and also by a wall 30 of the housing 14. Each of the heat pipes is of heat conductive material eg copper, has been evacuated, and contains a wick of porous material 34 soaked with a liquid. The porous material may be wire screen, glass fibre, or cloth of natural or synthetic fibre. The liquid soaked into the wick may be water, an alcohol, a fluorohydrocarbon or aqueous ammonia. As shown in Fig. 5, heat pipes 64 each have a wick 34 extending longitudinally of the pipe and a wick 66 at one end. The heat pipes are of airfoil-like profile, have fins 86 and are mounted so as to form an assembly rotatable by a drive pulley 58. Rotation of the assembly pumps a fluid F 1  (such as hot air or water) through a volute chamber 50. A second fluid (eg liquid) passes as indicated at F 2 . Annular seal members 84 contact a hoop 76 forming part of the rotatable assembly. It is mentioned that apparatus according to the invention may be a cooling system of a water-cooled engine.

Moulds.-Relates to multiple mould-boxes, designed particularly for making concrete paving slabs, of the kind comprising a row of partition plates clamped between distance-pieces, which form opposite ends of each mould. According to the invention, longitudinal clamping-bolts are provided, which do not engage the partition plates, but pass through the distance-pieces only, so that by merely slackening the nuts of the bolts, the latter, together with the distance-pieces, may be drawn away laterally from the moulded articles and partition plates. The distance-pieces a are preferably of channel section, and are all bored near their top and bottom ends so that bolts c, each headed at c<1> and provided with a nut c<2>, may connect the assemblage and enable the parts to be clamped together. To prevent the sides of the mould from bulging, some of the partition plates d are detachably secured at their ends to the distance-pieces, by means of bolts g. These connected plates, which extend beyond the bolts c, have at their edges recesses f, Fig. 2, through which the bolts pass, so that when the bolts g have been removed, the plates present no obstruction to the lateral withdrawal of the bolts c and distance-pieces.
