Title: Magnetically operated simulated eye assembly for toys
IPC: A63H3/40
Filed: 1967-03-07
Abstract: 1,120,654. Eye opening and closing means. DE LUXE TOPPER CORP. 7 March, 1967 [5 July, 1966], No. 10611/67. Heading A6S. A simulated eye for use in a toy comprises a housing adapted to be located in the head of said toy, an eye assembly pivotally mounted within said housing and magnetic means secured to and rotatable with said eye assembly which magnetic means may be influenced by a control magnet to cause said eye assembly to pivot within said housing thereby causing the eye to appear to open and close. Fig. 2 shows in section the eye socket 12 of a toy in which the housing of a simulated eye is accommodated. Each housing comprises a body 13 and a cover 19 provided with an elliptical opening 21 at its centre. Pivotally mounted in the housing by pintles 28 is the eye assembly, which comprises two portions a hemispherical shell 18 bearing on its outersurface the representation of an eye and an armature portion 30 which is attached to shell 18 via posts 24 (figs. 4 and 6 not shown) bottom post 25, and lip 26, which are dimensioned such that armature 30 is a snap fit in shell 18. The eye-assembly is perfectly balanced around the axis defined by the pintles 28 so that once the assembly is placed in any given position it maintains that position regardless of the orientation of the toy. An opening 42 in the central section of the armature contains a disc-shaped magnet 44 tightly fitted therein. The centres of the end faces of the disc coincide with the pintles 28 so that the magnet is balanced about the same axis as the eye assembly. The magnetic axis is preferably normal to the pivot axis extending from the front to the back of the housing. To operate the eye, a control magnet 48 is brought adjacent to it when the magnetic force causes the eye to pivot, the amount of movement being governed by the interaction of ledges 15 and 17 of the housing and projecting leg 36 of the armature. In an alternative embodiment fig. 7 not shown the housing is surrounded by a solenoid which is activated from a battery via a reversing switch. When operation of the switch reverses the magnetic direction of the solenoid and moves the eyes accordingly. In a further embodiment fig. 8 not shown the rear of the housing is fitted with an electromagnet the polarity of which may be changed via a reversing switch again manipulating the eye. In other embodiments fig. 9 and 10 not shown coils situate adjacent each eye are activated by switch means and battery to manipulate eye assemblies which are in the case of fig. 9 biassed by a magnet or by ballast into a particular orientation which bias is overcome by the magnetic influence of the coils or wherein the case of fig. 10, the reversal of the coil field is achieved using a circuit wherein one end of the coil is in circuit with switch means and the other end is connected to a centre tap of the battery. The toy preferably includes two eye assemblies each activated by a separate solenoid or coil.

Title: Production of colour effects on or in the oxide film of anodised aluminium or aluminium alloy
IPC: C25D11/18
Filed: 1944-06-05
Abstract: 584,940. Colouring aluminium and alloys. CAMPBELL, W. J. June 5,.1944, No. 10733. [Class 93] Characteristic designs and/or colour effects are produced on or in the oxide film of coloured or uncoloured anodised aluminium or aluminium alloy articles by causing a resist substance to form on the surface of a liquid and then transferring it to the article, after which the article is dyed, bleached or subjected to other chemical treatment. Specified resists are modified phenolformaldehyde resin, sandarac, cellulose lacquers, colophony, copal, mastic, dammar, kauri, shellac, canada balsam, amber, rubber, bitumen, castor oil, linseed oil, olive oil, lard oil, oleic acid, mineral oil, lanoline, poppy oil, tung oil, paraffin wax, beeswax, carnauba wax and hard animal fats. Solvents for the resists are benzene, turpentine, xylol, alcohol, solvent naphtha, acetone, lavender oil, trichlorethylene, and amyl acetate. Metallic driers such as lead or manganese soaps, and camphor may be used to modify the resist. In examples: (1) A resist A (a modified cresolformaldehyde resin, turpentine and benzene) is pipetted on to the face of water in a tank and spread into a film. The article is then immersed, carrying a broken film of resist, the surface of the water cleaned, the article withdrawn, dried and hardened by heat. The article is now coloured and the resist removed. The resist may be produced by first immersing the article in water, forming the resist on the water surface and then removing the article. The benzene in the resist may be replaced by raw linseed oil. (2) A resist B (mod-cresol-formaldehyde, linseed oil, turpentine and benzene) is used as in (1). (3) A resist C (sandarac gum and alcohol) is used as in (1). (4) A resist D (paraffin wax and benzene) is dropped when molten on to a water surface. Different resist patterns may be produced either by raising the temperature of the water before applying the resist or by playing over the water surface with a small flame. The resist is then used as in (1). (5) Resist B is pipetted on to a surface and a brush dipped in resist E (castor oil, modified-cresol-formaldehyde, and benzene) is used to draw a pattern on the surface after which the process of (1) is carried out. (6) The process of (5) is carried out and the article dyed. These two steps are carried out several times using different dyes. Specified dyes are Tartrazine, Solway Blue SES, Lissamine Fast Red BS, Solochrome Red BS. A selective stripping agent (e.g., ammonia or nitric acid) may be used to remove selected colours.
