Title: Manufacture of dyestuffs of the phthalocyanine series
IPC: C09B47/00
Filed: 1936-02-29
Abstract: Phthalocyanines are obtained by using as starting material the condensation product of diamino-maleic acid dinitrile with a compound containing the group --CO.CO-- or the group --CO.CH(halogen)--, such as diacetyl, glyoxal, benzil, o-benzoquinone, acenaphthenequinones, thionaphthenequinone, phenanthrene-quinone, aceanthrenequinone, or o -halogenacetophenone.  The dinitrile of the pyrazine series so obtained, which contains the grouping <FORM:0471418/IV/1> is heated, e.g. at 100--300 DEG  C. with or without a solvent, diluent and metal salt.  In examples: diaminomaleic acid dintrile is heated with (1) glyoxal to produce pyrazine-2 : 3-dicarboxylic acid dinitrile, which is then heated with cuprous bromide and pyridine to form the copper phthalocyanine complex: by using sodium amylate in place of the copper salt the metal-free dyestuff is obtained; (2) diacetyl to form 5 : 6-dimethyl-pyrazine-2 : 3-dicarboxylic acid, which is then converted to the dyestuff as in (1); (3) benzil to form 5 : 6-diphenylpyrazine-2 : 3-dicarboxylic acid dinitrile, then treated as in (1); (4) acenaphthenequinone to form peri-naphthylene-5 : 6-pyrazine-2 : 3-dicarboxylic acid dinitrile, then treated as in (1); (5) thionaphthenequinone to form 5 : 6-(2<1> : 3<1>-thionaphthene)-pyrazine-2 : 3-dicarboxylic acid dinitrile, then treated as in (1); (6) o -chloracetophenone to form 5-phenylpyrazine-2 : 3-dicarboxylic acid dinitrile, which is then melted with a trace of nickel to form the phthalocyanine complex. The products of example (5) can be sulphonated to produce a sulphonic acid having substantive properties for vegetable fibres.

Title: Device for compressing a workpiece of loose plies of material  and for driving a staple therethrough
IPC: B27F7/26
Filed: 1973-02-08
Abstract: 1416793 Stapling TEXTRON Inc 8 Feb 1973 6242/73 Heading B4C A stapler for compressing together loose plies of material and driving and clinching a staple therethrough comprises a tubular part 40 having a reservoir 84 supplied with compressed air and manually controlled means such as a triggeroperated valve assembly 32 and a sequencing valve assembly 36 to communicate the reservoir sequentially with a pressure chamber 24 for pivoting an L-shaped clinching member 22 about a pin 126 into engagement with the material and with a drive chamber 28 for driving a staple from a magazine 18 through the material and against an anvil 118 of the clinching member. The clinching member 22 has an adjustment screw 124 at its upper end and is normally urged to the disengagement position shown by a pair of springs 114 acting against a cross-bar 130 welded to the clinching member. When the trigger 146 is operated to lift the valve 136, air passes along a passageway 144 to drive a piston 26 for the clinching member 22. After the clinching member has moved to compress the workpiece between its anvil 118 and the stapler nose piece 14, the pressure build-up in the chamber 24 is sensed within the chamber 80 of the sequencing valve assembly 36 through a flexible tube 112. This pressure acts to disengage a valve 100 and thereby exhaust a pilot chamber 76 to atmosphere and cause a main valve 72 to move rearwardly and communicate the reservoir with the drive chamber 28 in which a drive piston 30 operates to drive a staple through the workpiece. Upon the release of the trigger, the valve 136 exhausts the pressure chamber 24 to permit the clinching member to return to its open position under the action of the springs 114. The exhaust is sensed by the sequencing valve assembly 36 to close the main valve 72 and permit the return of the drive piston 30 by means of compressed air stored in a plenum chamber 156. The drive piston 30 may be provided with a bumper 162.

Title: New compounds of uranium and their utilisation in energy-producing devices
Inventor: HOLLINS CECIL
IPC: G21C3/42
Filed: 1942-05-13
Abstract: An inorganic salt of uranium is reacted with a salt of a different metal, e.g. a sodium or aluminium salt, of an aliphatic acid containing more than 8 carbon atoms and in which at least part of the hydrogen has been replaced by deuterium, to give a uranium salt of a deuterated higher aliphatic acid. Alternatively, the latter may be obtained by treating a uranium salt of the higher aliphatic acid with deuterium in the presence of a hydrogenation catalyst.  In the preparation of the deutero salts, the ordinary aliphatic acid salt such as the sodium or aluminium salt is heated with heavy water in the presence of alkali and a hydrogenation catalyst such as active platinum, and the resulting product reacted with an inorganic salt of uranium. Means for cooling or utilizing the heat generated must be employed.  In the production of uranium hexadeuterostearate by bringing about double decomposition between uranium hexafluoride and aluminium deuterostearate the aluminium fluoride produced as a by-product may be reacted with uranyl fluoride (UO2F2) to regenerate uranium hexafluoride. Specification 690,861, [Group XL (a)], is referred to.

Abstract: 408,789. Valve circuits for wireless reception. BROWN, R. D., Ontario Street, Philadelphia, U.S.A. March 3, 1933, No. 6530. Convention date, March 3, 1932. [Class 40 (v).] Voltage for automatic volume control is derived from the input circuit of a grid-leak detector which may be of the screen-grid or pentrode type. As shown in Fig. 2, the screening grid is interposed between a main control grid and an auxiliary control grid 15 which is connected at 16 to the upper end of the input coil. A radio-frequency choke 18 allows the auxiliary grid to be fed with the rectified audio-components derived from a resistance R, in the grid-cathode circuit, so that the valve functions as a combined detector and low-frequency amplifier without overloading. The D.C. component across the resistance R is fed back through a lead 12 including a filter circuit to the grid of the preceding HF stages for automatic volume control. In Fig. 3, one of the control grids 17 is connected to the lower end of the input coil, to handle the audio voltages derived from the resistance R. A filter resistance may be inserted in series with this grid, and a condenser shunted across it, to exclude radio frequencies. In an alternative arrangement, the detector LF amplifier is of the pentode type.

In order to produce an opalescent effect the interior surface of the glass bulb of an electric incandescent lamp is coated with an adhering layer of titanium dioxide and a binder, the thickness of the layer and the particle size of the titanium being such that not less than 95 per cent of the light entering the layer is emitted uniformly by the corresponding external surface of the bulb. Preferably, the coating layer comprises titanium dioxide of not less than 98 per cent purity and a liquid binding medium consisting of a 2 per cent solution of nitrpcellulose with ethyl lactate as a plasticizer, and a thinner of butyl acetate and the same plasticizer, this mixture being subjected to prolonged grinding in a ball mill. Before the coating is applied the interior of the bulb is washed thoroughly with a cleansing solution, then rinsed with water at 80-90‹ C., subjected to the action of steam, and finally dried by warm air. The suspension may be applied to the inside of the bulb by spraying, pouring, or other methods, e.g. an excess of the suspension is poured into a bulb and the latter is rotated about its axis while allowing the suspension to drain slowly out, after which the bulb is inverted for about an hour to drain off the excess. The bulb may be heated subsequently to a temperature of between 450‹ and 550‹ C. to evaporate the volatile contents of the suspension. The internal surface to which the covering is applied is preferably frosted internally to promote adherence of the covering thereto. Specification 737,861 is referred to.
