Title: Improvements in or relating to safe-load indicators for cranes and like hoisting apparatus
IPC: B66C23/90
Filed: 1946-08-20
Abstract: 616,022. Cranes; winding and paying-out apparatus; lifting and lowering. AITKEN, R. L. Aug. 20, 1946, No. 24808. [Classes 78 (ii), 78 (iv) and 78 (v)] In a safe load indicator of the kind in which a change of tension in a member is arranged to react on spring means, the deflection of which is arranged to operate indicating and/or control means, the spring means comprises two springs having different natural periods of vibration forming a vibration damper. Clamps 24, 25, Figs. 1 and 2, secure the indicator between two parallel cables under tension, which are anchored to, and remain fixed with relation to, a part of the crane, said indicator serving to deflect the cables out of the straight so that variations of cable tension transmit a reaction transverse to the length of the cables to the two concentrically arranged springs 18, 19, having different natural periods of oscillation and constituting a vibration damper, contained between the yoke pieces 10, 11, the latter being free to slide along rods 12 towards the yoke 10 which is fixed thereto. Movement of the yoke 10 moves the micro-switch 23 into engagement with the abutment 22 adjustably secured to the casing 20. In a further embodiment, the indicator is attached at 36, Fig. 4, to a fixed part of the crane and at 29 to a tension member 30 which swings with the jib and which when under tension moves a yoke piece 26, carrying micro-switches 38, 39, against the action of vibration damping springs 18, 19. The switches are operated by a bridge piece 40 carried at the end of a spindle 41, the other end of which is attached to a cam-following roller 44 which is moved against the action of a spring 45 by cams which are shaped to correspond to two possible loading conditions of the crane.

Title: Composition and process for anodizing aluminum and its base alloys
IPC: C25D11/14
Filed: 1965-05-27
Abstract: Aluminium and its base alloys are anodized in an aqueous solution containing at least 5 g/l sulphosuccinic acid and at least 0.5 g/l sulphuric acid.  For coloured-as-formed oxide coatings the solution should contain less than 15 g/l sulphuric acid such coatings may be formed from a solution at 60 to 90 DEG  F. and a current density of 12 to 64 ASF containing 2 to 12.5 g/l sulphuric acid and at least eight times the quantity of sulphosuccinic acid in the range 25 to 900 g/l. The sulphate and/or sulphosuccinate radicles may be provided by suitable salts, e.g. the Na salt, providing that sufficient hydrogen ions are present to give the required free acid contents. The aluminium content of the electrolyte is preferably kept between 0.1 and 1 g/l by ion-exchange treatment since it reduces the effective sulphosuccinic acid concentration by 20 times its own value.  The oxide coatings may be dyed and sealed.

Patent GB-920864-A (GB)
Title: Purification of phenol
IPC: C07C37/86
Filed: 1961-07-12
Abstract: Phenol derived from cumene is purified by subjecting the impure phenol to fractional distillation to remove acetone, heating the substantially acetone - free phenol - containing material under acid conditions with an acid catalyst until the benzofuran content of the reaction mixture has been reduced to a practical minimum, and subjecting the reaction mixture to fractional distillation to recover a purified phenol-containing material.  The phenol starting material may be subjected to fractional distillation to remove both high-boiling and low-boiling impurities before being treated as above.  Suitable catalysts include mineral acids, strong organic acids, acidic clays, acidic ion exchange resins, boron trifluoride and the halides, sulphates and nitrates of copper, chromium, mercury, platinum, zinc, cadmium, gallium, vanadium and the metals of Group IV and VIII of the Periodic Table having an atomic number less than 52, the preferred catalysts being those of the Friedel-Crafts type.  The amount of catalyst is generally in the range 0.005% to 5% by weight based on the weight of phenol-containing material.  The process takes place between 40 DEG C. and 182 DEG C. at atmospheric pressure, but pressures higher or lower than atmospheric may be used.  It is desirable to have as little water present as is practical.  The process may be applied to a phenol which has been treated with a base as in Specification 883,746 and fractionally distilled to remove reaction products from the phenol before being heated in the presence of the catalyst.  Detailed examples are given in which the acid catalysts used are ferric chloride, sulphuric acid, chromic chloride, mercuric chloride, acid-treated bentonite, p-toluene sulphonic acid and platinum chloride.  Other specific catalysts are mentioned. Specification 865,677 also is referred to.

Abstract: 667,769. Safety devices for aircrew. K.A.C., Ltd. Sept. 28, 1949 [Oct. 8, 1948; Oct. 8, 1948; Sept, 2, 1949], Nos. 26294/48, 26295/48, and 22821/49. Class 4. [Also in Group XXXII] Forward movement of a pilot or passenger of an aircraft relative to his seat is controlled bv a chain or cable 13 connected between his harness 15 and an operative element of an hydraulic damping device 1 (see Group XXXII) rigid with the airframe 2. The action of the damping device may be controlled manually by a handle 77 and an associated Bowden cable connection 84. A gate (Fig. 5) provides three positions 116, 115, 117, for the handle 77. In the position 116 the damping device is rendered inoperative, and a return spring tends to move the handle from 116 to position 115 in which it is retained by a stop 113. In the position 115 the effect of the damping device is such that the pilot is free to move forward provided his speed relative to his seat does not exceed a predetermined amount. His movement is progressively resisted as the relative speed increases, until the liquid flow path in the damping device is closed to entirely restrain movement of the pilot. When this occurs, mechanical locking means in the damping device maintains the flow path closed until the lever 77 is returned to position 116. By flexing the handle 77 laterally against spring means (not shown), it may be moved from 115 to position 117. In this position, the flow path in the device 1 becomes closed on the slightest relative movement between the pilot and his seat. A single damping device may serve more than one member of an aircrew and may be applied to protect a rearwardly facing airgunner against the effect of acceleration.
