Abstract: 1,232,867. Retractive switches; switch contacts. POLYCONTACT A.G. 19 June, 1968 [14 Feb., 1968], No. 22281/70. Divided out of 1,232,866. Heading H1N. Contact chatter is reduced in a snap-action switch by the provision of a lateral tongue, e.g. 8 or 9 on the moving contact blade 4 whose edge co-operates with a contact face e.g. 10 or 11 which is arranged obliquely to the direction of movement of the moving blade 4 and is resiliently supported so that it yields on being engaged by the moving contact blade 4 and a sliding damping movement occurs between the fixed and movable contacts. A push button 6,moves the moving contact by means of a cantilever spring 5 and C-shaped snap-action spring 7. The oblique face 10 or 11 is provided by the bent over end of a blade spring 12 or 13 clamped between a supporting spring 2 or 3 and a member 16 or 17. Movement of face 10 or 11 is limited by cooperation of a re-entrant portion with spring 2 or 3. The fixed contacts may be bifurcated by means of a longitudinal tapered slot, a longitudinal slot or an inclined offset slot so that each fork oscillates at a different frequency. The contact forks may occupy different rests positions so that they are engaged sequentially by the moving contact. Alternatively the contact edges of the moving contact may have different size forks to engage the forks of the fixed contacts sequentially. The forks may be given different frequencies by making them of different density materials or, by subjecting them to different cold working or heating operations, by making them of different thicknesses or by making them of different lengths. The cooperating contact forks may encounter different frictional resistances.

Novel compounds of the general formula wherein R 1  is a halogen atom, a C 1 -C 4  alkyl radical, or a phenyl, cyano, carbamoyl or thiocarbamoyl group and R 2  is H, halogen, or NO 2 , are obtained by reacting (C 2 H 5 O) 2 P(S)Cl with an indazole derivative of the formula wherein M is H or an alkali metal. The reaction is preferably carried out in an aprotic polar solvent e.g. 2-N-methyl pyrrolidone, dimethylformamide, hexamethylphosphotriamide or dimethylsulphoxide at 0-30 C. When M is an alkali metal the alkali metal derivative can be prepared in situ e.g. by treating the indazole in which M is H with an alkali metal alkoxide in an alcohol. The products have insecticidal and fungicidal properties and may be admixed with one or more solid or liquid diluents or adjuvants to form conventional compositions which may also contain wetting, dispersing or emulsifying agents. 3 - Carbamoyl - 5 - nitroindazole is obtained by the action of nitric acid on 3-cyanoindazole in solution in sulphuric acid. 3 - Thiocarbamoylindazole is obtained by the action of HCl and O,O-diethyldithiophosphorie acid on 3-cyanoindazole in benzene solution. 3 - Carbamoyl - 5 - chloroindazole is obtained by the action of sulphuric acid on 3-cyano-5- chloroindazole which is itself obtained by reacting sodium chlorate with 3-cyanoindazole in solution in acetic acid.

Abstract: 1,265,568. Electrolytically initiating chemical etching of chromium. CORNING GLASS WORKS. July 24, 1969 [July 30, 1968], No.37237/69. Heading C7B. A method of producing a patterned article by etching a layer of Cr deposited on a substrate, comprises the steps of depositing the Cr layer on the substrate and allowing the Cr to develop a thin surface oxide layer, applying a masking material to selected areas on the exposed surface of the oxide-covered Cr layer, contacting the unmasked portions of the layer with an acid etching solution having a chloride ion concentration so adjusted that the solution will not chemically react with the oxide covered Cr layer but will react with Cr metal, generating an electrical potential across the oxide surface of the Cr layer to permit chloride ions to permeate the oxide layer and initiate a selfsustaining chemical action between the Cr metal and the etching solution, continuing such chemical reaction for a time sufficient to remove a portion of Cr, and then discontinuing the chemical etching. The etching solution may comprise HCl or NH 4  Cl. Fig. 2 illustrates etching of a Cr layer 14 on a glass or ceramic substrate 12. The Cr layer has a thin surface oxide layer 20 (formed by exposure of the Cr to air in normal handling) and is covered in part by an acid-resistant barrier material 16. The potential is applied by means of an electrode 26 of any metal in the electro-chemical series capable of displacing Cr (e. g. Al or Zn) connected by a wire to a Pt electrode 24. Once etching has begun the electrodes may be removed. Fig. 1 (not shown), illustrates an arrangement where a hand-held probe (22) of the same material as the electrode 26 touches the surface of the oxide-coated Cr layer but is unconnected to a counter electrode. Instead of using a hand-held probe (22), a clip of Zn or Al may be attached to the work. Fig. 3 (not shown) illustrates a further arrangement similar to that shown in Fig. 2 but wherein both electrodes (30) (32) are of Pt and there is an external current source (34) connected to the electrodes. The workpiece and solution may be agitated (e.g. ultrasonically) to remove hydrogen bubbles.

In the condensation, the functional groups in monomer (D) (when it is used) or the compound containing such groups (when (D) is not used), react with the halogen atom in the chloroalkyl ester group of monomer (A). The condensation is preferably carried out in the presence of a base and at 0-250 C. Elasticizing monomer (B) may be for example a C 1-20  alkyl ester of acrylic acid, a C 4-20  alkyl ester of methacrylic acid or a C 4-6  conjugated diene. Monomer (C) may be, for example, a C 1-3  alkyl ester of methacrylic acid, a nitrile of a 6 3-5  α.#-unsaturated carboxylic acid, a vinyl, vinylidene, divinyl or divinylidene compound other than those used as the other monomers, or a C 2-10  α-mono olefin.

Many examples of compounds used if monomer (D) is absent, are listed. The product may be derived from a mixture of a copolymer of (B), (C) and/or (D), and a polymer of (A).

Abstract: 1294941 Electron-beam magnetic deflecting apparatus ILLINOIS TOOL WORKS Inc 13 Jan 1970 [13 Jan 1969] 1623/70 Heading H1D A magnetic deflection yoke for a cathode-ray tube, especially a colour television tube, is supported by means which allow independent adjustments of the angular and axial positions of the yoke. Fig. 1 shows an exploded view of the assembly wherein the deflection yoke 22 is surrounded by a clamp 30 having radially extending arms 138 adapted to engage in guide slots 72 in the surrounding mounting means 24 whereby rotation is restrained but axial movement is permitted. A ring 28 is provided, with helical slots 100 engaged by reduced end portions 140 of arms 138, so that rotation of the ring 28 produces axial movement, of the deflection yoke; after such axial movement a screw 148 may be used to lock the clamp 30 in the selected position. A screw 128 on the clamp 30 may be slackened when the deflection yoke is to be rotated, and tightened again afterwards. The mounting means 24 is provided with tabs 64 adapted to engage the conical part of the tube and may be secured to the tube by an adhesive or by wires. The axially extending arms 70 containing the guide slots 72 may terminate in a web 86 provided with an aperture 88 for the neck of the tube, and may be provided with fastening means 90 to which a panel 32 may be secured. This panel may support radial convergence magnets for the tube plus associated circuitry and may take the form of a printed circuit board. In a modification, Fig. 9 (not shown), one of the helical slots 100 is formed in a separate axially adjustable plate mounted on the ring 28, so that such axial adjustment produces tilting of the deflection yoke. In another modification (Figs. 10-14, not shown),' the web 86 is omitted and the panel 32 is secured to the arms 70 by means which allow it to be rotated and then clamped in the required angular position. The clamp 30 is formed in two parts, an inner clamp which clamps the ferrite core of the deflection yoke together and an outer clamp which locks the yoke against rotation. In another modification (Fig. 15, not shown), the chordal resilient members 52 which engage the ring portion 36 of the yoke, are replaced by resilient bridges inside the ring 50, and the central aperture in web 86 is square with adjacent slots to allow the sides of the square to distort to the shape of the tube neck.
