Title: Improvements relating to paints and like coating compositions and their manufacture
IPC: C09D101/12
Filed: 1939-08-23
Abstract: 532,224. Cellulose ester compositions. COUNTY CHEMICAL CO., Ltd., and HAMBREKS, L. G. Aug. 23, 1939, No. 24223. [Class 2 (ii)] In the production of cellulose acetate paints or coating or adhesive compositions, the cellulose acetate is damped with methylated spirit and dissolved in a mixture of carbon tetrachloride and methylene chloride so as to form a smooth liquid jelly. The jelly is suitable for use as a transparent adhesive cement for aeromodels and like purposes. Aluminium powder may be added for making a metallic paint. Dyes or pigments may be added for making coloured lacquers. For aeroplane dope, sufficient butyl alcohol and triphenyl phosphate may be added. Cellulose acetate may be damped with 64 o.p. methylated spirit. The mixture is stirred during the addition until the spirit has been absorbed. It is then stirred with a mixture of carbon tetrachloride and methylene chloride. Camphor and triphenyl phosphate are added and the resultant liquid is allowed to stand until a clear jelly is produced. Aluminium powder and further quantities of carbon tetrachloride or methylene chloride and methylated spirit may be added to this base to form a metallic paint. Swedish wood pulp may be added to the base to produce a cement for balsa wood. Amyl acetate may be added to the base to form an adhesive glue for aeroplanes. A coloured lacquer may be obtained by adding butyl alcohol, amyl acetate, and pigment to the base composition.

Title: Improvements in or relating to selector switches
IPC: H01H67/22
Filed: 1926-10-01
Abstract: 259,562. Crowe, D. C. Oct. 12, 1925, [Convention date]. Automatic exchange selectors. - A series of interlocking armatures associated with a single magnetic system are operated successively in response to impulses in a control circuit. In the form shown in Figs. 3, 4, 6 the magnetic system consists of a long bar 6, end magnets 4, 5, and connecting pieces 7, 3 together forming a closed magnetic circuit. Opposite each armature 1 the bar 6 has a polepiece 9 and a tapping from its winding 10, which is connected in series with the magnets 4, 5. As will be understood from Fig. 6, if ground is connected from the control circuit 15 to a tapping, a consequent pole is formed at that point and the corresponding armature is attracted. When the control circuit is opened the armature falls back and operates transfer contacts 11, 12, 13 so that the next closure of the control circuit produces a consequent pole opposite the next armature. Each armature 1 carries a spring 33, Fig. 3, connected by a link 32 to the spring 13, these parts being normally in a position slightly lower than shown in the Figure, with an abutment 41 locked under a catch-spring 43, but the attraction of the previous armature unlocks the abutment by means of a pin 47 engaging an extension 48 of the catch 43, and the parts then move to the position shown, with the spring 33 bearing on a rod 35. When the armature is attracted it unlocks the link 32 of the next armature and a pin 29 raises springs 17, 18, 19 to engage multiple strips 20, 21, 22. When the armature is released it strikes a stop 34 on the spring 33 and overshoots the position shown sufficiently to lock the abutments 41 under the catch 43, making contact 13, 12 and breaking contact 12, 11, so as to transfer the control circuit to the next tapping. If the device is used as a numerical selector, it must after service be supplied with the appropriate number of impulses to bring it to normal condition. No transfer contacts and no link or catch are needed for the first armature (which is energized at the 10th closure of the control circuit) and this armature is arranged to unlock the next one when it falls back instead of when it is attracted. In a modification, the armature itself is locked in its retracted position and is unlocked by the falling back of the previous armature. In the construction shown in Fig. 9, the armatures 52 are pivoted round a single magnet 51, and at any given moment all the armatures except one (the one to the left of the Figure as shown) are locked in their retracted positions by catches 55. The next energization of the magnet attracts the unlocked armature, which on falling back overshoots its resting position so as to unlock the next armature and to lock itself. In this construction no transfer contacts are necessary.

Hydrocarbon derivatives specified are: chlorethane, ethylene dichloride, trichlorethylene, carbon tetrachloride, chlorpropane, chlorbutylene, chlorbenzene, brombenzene, nitroethane, nitrobenzene, amylamines, aniline, pyridine, and petroleum bases.  The quaternary ammonium base may contain alkyl, unsaturated alkyl, aryl, or aralkyl groups with or without substituents such as OH, NH2, NO2, halogen, or heterocyclic groups.  Specified bases are trimethyl tolyl ammonium hydroxide and trimethyl benzyl ammonium hydroxide.  These are dissolved in water or other solvent such as liquid ammonia, lower alcohols (ethyl, methyl, or propyl alcohol, glycol, glycerol, chlor hydrin), amino alcohols, alcohol-ethers (ethylene glycol mono ethyl ether), acetone, or ethylene diamine.  Alkali hydroxides such as ammonia or calcium hydroxide may be added.ALSO:Hydrocarbons or derivatives thereof are freed from acid-reacting organic substances by extraction with a quaternary ammonium base and separating the resulting liquid layers. Petroleum, benzene, toluene, xylene, chlorethane, ethylene dichloride, trichlorethylene, carbon tetrachloride, chlor-propane, chlor-butylene, chlorbenzene, brom-benzene, nitroethane, nitrobenzene, amylamines, aniline, pyridine, or petroleum bases may be treated.  The quaternary ammonium bases may contain alkyl, unsaturated alkyl, aryl, or aralkyl groups with or without polar groups such as OH, NH2, NO2, halogen or heterocyclic groups substituted therein, which lower the solvent power but increase the solubility of the base in water.  Branched aliphatic, olefinic or aromatic groups increase the solvent power. Examples: trimethyl tolyl ammonium hydroxide, or trimethyl benzyl ammonium hydroxide. Petroleum is freed from mercaptans, phenols, naphthenic acids, and fatty acids by the process.  The quaternary ammonium base is dissolved in water or other solvent such as liquid ammonia, lower alcohols, (ethyl, propyl, or methyl alcohol, p  glycol, glycerol), chlorhydrin, amino alcohols, alcohol-ethers (ethylene glycol mono-ethyl ether), acetone, or ethylene diamine. Alkali hydroxides may be added, e.g. ammonia, calcium hydroxide. The quaternary ammonium base may be recovered by steam distillation, electrolytic oxidation, treatment with oxygen in the presence of copper oxide or salts, or by treating with mineral acids, distillation, and extraction with methyl alcohol, depending on the acid substances removed.  If the initial material contains hydrogen sulphide, hydroxy or carboxy acids, a pre-treatment with alkali hydroxide, or tri-potassium phosphate may be used.

Abstract: 1,202,860. Alarm clocks. SUNBEAM CORP. May 14, 1969 [July 1, 1968], No.24689/69. Heading G3T. An alarm clock includes intermittent alarm mechanism comprising an alarm restraining member 102 pivotally mounted on the clock frame and having a projecting part 106 adapted to ride against the periphery of a disc 103, having at least one peripheral notch 115 and driven by the clock movement, in such manner that a free end 108 of the member 102 presses against the vibrator 43 of the alarm mechanism to prevent the sounding of the alarm until the part 106 drops into the or a notch 115. The clock illustrated is driven by an electric motor, the field coil of which co-operates with an armature on the vibrator 43 to energize the latter electromagnetically. An alarm lever 48 is normally engaged with the vibrator 43 and pivoted to release the latter at the preselected time for the sounding of the alarm. The alarm may be sounded intermittently under the control of the rotating disc 103, or it may be set to sound continuously by manual adjustment of an eccentric pivot 121, on which the member 102 is mounted, to so space the end 108 of the latter from the vibrator 43 that the rotating disc 103 is ineffective to stop the vibrations. The alarm is shut off by movement of a member 50, guided vertically by screws 53, 54, into engagement with the vibrator 43. The intensity of the alarm sounds is adjustable by rotation of an eccentric cam member 76 Fig.1 (not shown) to vary the force applied by a spring against the vibrator 43. An electric lamp 82 Fig. 1 (not shown) is provided for illuminating the clock dial, and is energized via a potentiometer so that its intensity may be adjusted.

Title: Improvements in and relating to processes for the manufacture of acid alkali pyrophosphates
IPC: C01B25/42
Filed: 1936-09-14
Abstract: Acid alkali pyrophosphate particularly the sodium salt is obtained by heating alkali metaphosphate to 170--300 DEG  C., in the presence of steam, with or without the application of pressure. Preferably the heating of the metaphosphate is effected solely by the steam, and the conversion may be assisted by first moistening the metaphosphate or by addition of a volatile acid such as nitric acid.  Conversion is most rapid at about 200 DEG  C.  In a modification the conversion is effected by rapidly drying a solution of the metaphosphate at about 200 DEG  C. as on a heated drum, roller, or band.  Hexametaphosphate, obtained for instance as a fused mass from sodium chloride and phosphorus pentoxide, is advantageously used in the process, but trimetaphosphate or dimetaphosphate may also be employed.
