Title: Manufacture of zinc phthalocyanine pigments
IPC: C09B67/04
Filed: 1950-07-10
Abstract: Zinc phthalocyanines in dispersible form are obtained by grinding crude zinc phthalocyanine in the dry state with a solvent-removable substratum, until a pigment of strong colour is produced, removing the substratum with a solvent, and, if desired, drying.  Substrata specified are water-soluble compounds such as sodium meta-borate, sodium ferrocyanide, anhydrous calcium chloride, sodium carbonate, potassium aluminium sulphate, anhydrous barium chloride, finely - powdered sodium chloride, finely-powdered anhydrous sodium sulphate, ammonium chloride or sulphate, anhydrous boric acid, aromatic sulphonic acids or their alkali salts such as sulphanilic acid, anhydrous sodium and potassium hydroxides, sodium phenolate, and acetone-soluble compounds such as phthalic anhydride or p-toluene sulphonamide. The product is mainly b -modification but changes to a -modification on treatment with an aqueous solution, e.g. when removing the substratum, and if a strong greenish pigment is desired, this may be avoided by treating first with an organic liquid having a dissociation constant less than water, e.g. methyl or ethyl alcohol, acetaldehyde, acetone, dioxane, iso- and n-propyl alcohol, benzene, cyclohexanone, or benzonitrile.  The liquid may be present during the grinding step, in quantity such that the mix is in powder form. Water-immiscible liquid such as benzene or benzine may be used but in quantity insufficient to form a non-aqueous phase.  As an alternative to the organic liquid treatment, the dried product may be heated to 150-200 DEG  C. In examples, a crude zinc phthalocyanine produced from phthalonitrile and zinc dust in presence of a -chloronaphthalene is subjected to the treatments described above, using some of the substrata and organic liquids there specified.

Title: Improvements in automatic counting devices, especially for duplicating and printing machines
Inventor: BROWN ROLAND
IPC: G06M3/02
Filed: 1955-06-15
Abstract: 828,156. Counting-apparatus. BLOCK & ANDERSON Ltd. March 19, 1956 [June 15, 1955], No. 17282/55. Class 106 (1). [Also in Group XVI] An automatic pre-set counting device for stopping a power-driven machine for performing repetitive operations, after a desired number of such operations have been performed, comprises a ratchet wheel mounted for rotation to tension a restoring spring, a feed pawl adapted to be operated from a power-driven shaft to advance the ratchet wheel step-by-step against the spring tension, a pre-setting disc lockable in one of a number of angular positions for determining a selected number of steps to be completed by the ratchet wheel between an initial position wherein an abutment on the ratchet wheel engages an abutment on the disc and an end position, and means operative in said end position to disengage a check pawl to allow the ratchet wheel to return to its initial position, the feed pawl being lifted clear of the ratchet wheel on each return stroke of the feed pawl so that the ratchet wheel is free for return movement by the spring when the check pawl is disengaged. In the initial pro-set position of the ratchet wheel C, a post H thereon is urged by a tension spring G against a stop plate J on a pre-setting disc K, which is pre-set by means of a lug M on a locking lever L engaging one of say fifty teeth on the disc, so that the ratchet can rotate counter-clockwise against the action of the spring G through a desired number of steps each equal to one ratchet tooth before the post H strikes a trip-lever X to stop the machine. On each revolution of the printing drum, a cam T acts on a roller on a lever D to rock clockwise a lever N pivoted at O, whereby a feed pawl A pivoted on the lever N is moved away from a trip post B, and a spring A 1  engages the pawl with a ratchet tooth, further movement of the lever N causing the ratchet wheel to move one step counter-clockwise. On the first stroke of the lever N, the latter strikes an adjusting screw P 1  on a lug P of a retaining lever F to swing the latter clockwise and release a block R on the lever arm of a check pawl E, whereupon a spring E 1  moves the nose of the pawl E into engagement with a ratchet tooth to prevent clockwise movement of the ratchet wheel. The block R then prevents counterclockwise movement of the lever F. At the end of the desired number of revolutions of the printing drum, the post H strikes the lever S to stop the machine, and a post Q on the ratchet wheel strikes a cam face E 2  of the pawl E to move the latter clear of the ratchet teeth, whereupon the block R is moved to allow the lever F to re-engage it. The ratchet wheel is thereupon returned by the spring G to its initial pre-set position. If the disc K is set one step further clockwise than the position of the drawing, a blocking plate X on the ratchet wheel is brought into the path of the pawl A, and the machine runs continuously. Specification 769,707 is referred to.

Title: Improvements in or relating to drives for automobile vehicles, more particularly multi-wheel or endless-track vehicles
IPC: B62D11/08
Filed: 1935-06-17
Abstract: 440,160. Motor-vehicle driving-gear. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M., [Firm of]), Heidenheim-on - the - Brenz, Wurtemberg, Germany. June 17, 1935, No. 17403. Convention date, June 15, 1934. [Class 79 (ii)] Hydraulic means are provided for driving independently each side of a motor vehicle, more especially a multi-wheel or endless-track vehicle. Fig. 1 shows two power units A<1>, A<2> each driving a wheel E<1>, E<2> respectively through hydrodynamic turbo-gears B<1>, B2. A clutch F is provided for locking the two wheels E<1>, E<2> together for straight forward or backward motion, and separate brakes d3, d4 are provided for each wheel. A single steering wheel control G, Fig. 3, is provided for all these elements, and comprises a cam H which on rotation in either direction frees the clutch F. Further rotation in either direction effects gradual emptying of the associated turbo-gears for forward travel by means of a cam J, thus slowing down one drive and causing the vehicle to turn in that direction. Still further turning of the wheel G puts on the brake d3 or d<4> by means of a cam K, and final rotation releases this brake and causes a cam L to reverse the direction of rotation of the drive on the inside of the travel curve. An additional cam L<1> may be fixed to the cam L and be mounted to move axially to bring either cam into position to control the turbo-gear. The cam L<1> is of the same size and shape as the cam J, and may be the cam J itself, and effects reverse movement of both drives. The regulating devices of the motors A', A<2> may be so connected with the regulating devices of the associated turbogears B<1> and B<2> that when the gear is brought to a standstill the corresponding motor also ceases to run, and the motors A<1>, A<2> may be replaced by a single power unit operating both turbo-gears B<1> and B<2>.

Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/043
Filed: 1937-06-23
Abstract: In obtaining hydrogen peroxide by the oxidation of an organic hydrazo compound dissolved in an inflammable solvent in which the hydrazo-compound is soluble but in which hydrogen peroxide is insoluble, the oxidation is effected with an oxygen containing gas at a temperature such that the proportion of solvent vapour admixed with the oxygen-containing gas exceeds the upper explosive limit.  The resulting azo compound may be reduced again to the hydrazo compound and re-used in a cycle.  According to examples, (1) a solution of p-hydrazo toluene in benzene is oxidized at 57 DEG  C. by passing 97 per cent oxygen from a cylinder through a vessel in which the solution is stirred with water; (2) a solution of p-hydrazo toluene is oxidized with air at 59 DEG  C. in the presence of water; (3) a solution of p-hydrazo toluene in hexane is oxidized with oxygen at 45 DEG  C. in the presence of water.
