Title: Improvements in or relating to wheel mountings for vehicles
IPC: B60B9/00
Filed: 1929-05-27
Abstract: 330,749. India Rubber, Gutta Percha, & Telegraph Works Co., Ltd., and Avery, W. L. May 27, 1929. Addition to 312,139. Springs, arrangegment of; guiding vertical play; lateral canting.-The resilient mountings for the wheels of vehicles as described in the parent Specification, are modified constructionally in several respects such as by providing resilient elements adjacent one link only of each pair of links to restrain its angular movement and also by providing means for exerting a variable frictional resistance in addition to the resilient resistance. Figs. 1 and 2 show vertical sections on the centre lines while Fig. 3 shows a vertical section on the line 3-3 of Fig. 2. The wheel hub 8 is adapted to rotate on the outside of a cylindrical' casing 3 having end plates 1, 2 with vertical slots 15, so that the wheel and the casing may move vertically in a spring-controlled manner relatively to two tubes 19, 20 rigidly connected together and to the frame or undercarriage of a vehicle by fork members 24, 25. The wheel is constrained to move with its axis parallel to the axle tubes 19, 20 by parallel links 30, 31, the upper ends of which are pivoted at 28, 29 to a member 27 slidable on the axle tubes 19, 20 while the lower ends are pivoted to castings 34 secured to the end cover plates 1, 2. The arm 30 is in two parts arranged one on each side of the slidable member 27 and secured to spindles 32 which work in bearings 33 mounted in the castings 34. When road or ground shocks cause the wheel to move vertically relatively to the axle tubes 19, 20, the consequent rotation of the arms 30 is resisted by two resilient members each comprising groups of wedge-shaped india rubber blocks 43 with metal separating plates 53, arranged in annular casings 45 which are mounted to rotate on the outside of the bushes 33. The casings 45 are rotated with the arms 30 by a metal strap 59 one end of which is connected to the pin 28 while the other end is riveted to the outside of the casing at 61. When the arms 30 rotate in a clockwise direction, the rubber blocks are compressed between the movable abutment 50 bolted to the side of the casing 45 and the fixed abutment 49 bolted to the side of the casting 54. Movement in the reverse direction is cushioned by the rubber block 52. The radial separating plates 53 are held at their inner ends so that they cannot move outwards, and projections on the plates engage recesses in the rubber blocks and limit their movements when they are compressed. An increasing frictional resistance in addition to the resilient resistance is obtained by means of a wedgeshaped metal block 62 secured to the casting 34 so that it cannot rotate and bearing on the outside of the casing 45. The lining to the operating band 59 rides up the wedge-shaped end of the block 62 and gives an increasing frictional resistance.

Title: Process for the preparation of metal phthalocyanines
IPC: C09B47/06
Filed: 1944-08-29
Abstract: Hexadecahalogen-metal-phthalocyanines are manufactured by heating tetrahalogen aromatic o-dicarboxylic acids or their functional derivatives (e.g. anhydrides or imides, including derivatives containing chlorine and bromine in the same molecule) with urea and with metals or metal-yielding compounds (e.g. heavy metals in a finely dispersed form, their oxides or salts, preferably halides) in the presence of high-boiling inert organic solvents (i.e. those boiling above 100 DEG  C. at atmospheric pressure, e.g. naphthalene, diphenyl, hydrogenated and halogenated aromatic hydrocarbons, or especially aromatic nitro compounds such as nitrobenzene, nitrotoluenes, nitrochlorobenzenes and nitronaphthalenes) and of catalysts containing a metal or metalloid of the fifth or sixth group of the periodic system (including phosphorus, but not being the same as the metal used in forming the metal phthalocyanine).  The reaction is advantageously effected at 150-210 DEG  C., but preferably below 190 DEG  C.  The products are green pigments which are soluble in sulphuric acid and can be precipitated from solution therein by means of water, and which, in suitably fine subdivision, form green emulsions with oils and varnishes.  In examples: (1) tetrachlorophthalic anhydride is heated with urea, ammonium molybdate, cuprous chloride and nitrobenzene, yielding hexadecachlorocopper - phthalocyanine; (2) the cuprous chloride in (1) is replaced by ferrous chloride or other salts of iron to produce hexadecachloroiron-phthalocyanine; the ammonium molybdate may be replaced by ammonium vanadate, ammonium tungstate, arsenious oxide, arsenic acid or phosphorus pentoxide; (3) the cuprous chloride in (1) is replaced by cobalt chloride to give hexadecachloro - cobalt - phthalocyanine.  Other catalysts specified are arsenic trioxide, tungsten trioxide, the oxides of antimony, chromic oxide, ammonium dichromate, arsenic pentoxide and uranyl acetate.  Specifications 476,243 and 486,782 are referred to.  Samples have been furnished under Sect. 2 (5) of: (A) hexadecabromo-copper-phthalocyanine, obtained by heating tetrabromophthalic anhydride with urea, ammonium molybdate, cuprous chloride and a -chloronaphthalene; (B) the product obtained by heating an equimolecular mixture of tetrabromo- and tetrachloro-phthalic anhydrides with urea, ammonium molybdate, cuprous chloride and nitrobenzene; (C) hexadecachloro-zinc-phthalocyanine, obtained by heating tetrachlorophthalic anhydride with urea, zinc chloride, ammonium molybdate and nitrobenzene.
