Of particular interest are those compounds of formula in which X 2  is -O- and -NH- and R x  is hydrogen or halogen, or an alkyl, alkoxy, carboxyl, carboxylic acid ester, amide (substituted or unsubstituted) or nitrile group; or an alkyl group which is substituted by one or more carboxyl, carboxylic acid ester, carboxylic acid amide or nitrile, hydroxy, alkoxy or amino groups; a phenyl, alkyl phenyl or aralkyl group; an amino group which may be substituted; a sulphonic acid group, a sulphonic acid alkyl or aryl ester group, a sulphonamide group, a sulphinic acid alkyl or aryl ester group, an alkyl sulphone group, an alkenyl sulphone or an aryl sulphone group; m is 1-4; and in which two vicinal residues R x  together with the benzene nucleus to which they are attached may form a tetrahydronaphthalene ring. The compounds of the first formula given above may be formed by reacting a carboxyl compound of the formula ArCOZ, in which Z is hydroxyl or halogen and Ar is as defined above with an amino benzene of formula to give a compound of formula which is then heated to a temperature in the range 150-350‹ C. to form the desired compound. Alternatively compounds of the second formula given above are produced by reacting a carboxylic acid chloride of formula with an aminobenzene of formula to give an acyl compound of formula which is heated to form the required compound. Examples are given of the preparation of compounds in which X 1  in the 1st formula above is -O- or -NH- and the benzene nucleus B is unsubstituted or is substituted by one or two methyl groups, a tertiary-butyl, an α,α-dimethyl benzyl, or a tetramethylene group.

Abstract: 1,129,263. Timeswitches. SANGAMO WESTON Ltd. 27 Oct., 1965 [29 Oct., 1964], No. 44204/64. Heading H1N. A micro-switch 52 is moved "on" and "off" at selected times as the result of the temporary coupling of one or other of two constantlyrotating pawls with one or other of two toothed wheels. The "on" pawl 66 rotates with a motordriven member 15 (Fig. 2, not shown) and co-operates with pins 24a insertable, in selected holes in a fixed plate 12. When the pawl engages a pin 24a, the pawl is rocked about its pivot 64 to engage a tooth 69 with a toothed wheel 44 loosely carried by the member 15. The wheel 44 is thus rotated through a limited angle and a pin 45 thereon moves a switch actuating lever 47 to close the switch, the wheel being returned by a spring 49 (Fig. 2, not shown) when the pawl has moved past the pin 24a. The switch is held closed by a lever 57 which latches lever 47 until lever 57 is subsequently moved clockwise against spring action by a pin on the second toothed wheel 57 (Fig. 2, not shown) when this is engaged by the second pawl 65 (Fig. 2, not shown) at a time corresponding to a second pin similar to 24a, A rotary knob carries a member 39 which can be moved either way to engage lever 47 or latch 57 to provide a manual override, an indicator lamp being contained within the knob. The member 15 is set by hand to indicate the actual setting time and is. specially shaped so that it can only be rotated clockwise.

Title: Method of Making Shaped Epitaxial Deposits
IPC: H03G3/20
Filed: 1966-10-17
Abstract: 1,161,343. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 17 Oct., 1966 [24 Oct., 1965], No. 46250/66. Heading H1K. In the manufacture of a semi-conductor device a semi-conductor wafer is provided with an apertured mask, holes are etched into the wafer through the mask with side walls parallel to slower or faster growth rate crystallographic planes than the bases of the holes and semiconductor deposited on the faster growth planes. If the substrate is semi-insulating it isolates the material grown in the pockets. Growth may occur primarily either from the base or from the sides of the pockets depending on the crystallographic orientation. Where the substrate is of N- or P-type isolation of the material in the pockets may be achieved by depositing or growing oxide insulation on the bases of the pockets and possibly on part of the side walls thereof and then growing material of the same conductivity type on the exposed parts of the pocket walls to bury the oxide. Isolation of the grown material is completed before or after device configurations are formed in the pockets by converting the grown material lining the parts of the pocket side walls exposed during the epitaxial growth to the opposite conductivity type by diffusion, or by etching away this material. Alternatively, isolation is achieved by arranging that the first grown material is of opposite conductivity type to the substrate, or by filling the pockets with such material and then converting the central portions to the same type as the substrate by diffusion. In another embodiment, in which the pocket and substrate materials are of opposite conductivity types the intervening PN junction is relied on for lateral isolation. Transistor and resistor configurations are formed in adjacent pockets by diffusion and interconnected to form a logic circuit (Fig. 15, not shown) by tracks formed on an oxide overlayer by vapour deposition overall followed by selective etching. Conventional photo-resist and etching techniques are used to fashion the masking and insulating layers from silicon oxide produced by thermal growth or by low temperature oxidation of tetraethoxysilane. Alternative insulating materials suggested are carbon-rich silicon carbide and alumina. Where silicon is deposited the technique of hydrogen reduction of silicon tetrachloride may be employed, in which case the reaction can be reversed to effect etching of the silicon substrate. It is stated that germanium gallium arsenide, gallium arsenophosphide and A II BV I  compounds may be grown by the techniques described.

Abstract: 1,103,540. Dimming arrangements for fluorescent lamps. BRITISH LIGHTING INDUSTRIES Ltd. 18 Oct., 1966, No. 46548/66. Heading H2H. A circuit for operating parallel-connected filament-heated fluorescent lamps 10, 11 at normal or reduced illumination comprises a three-position switch 12 controlling a relay coil R having contacts rl, r2, r3, the arrangement being such that in one position (bright) of the switch 12 the coil is de-energized and the lamps are supplied from an auto-transformer winding 17 through contacts r2, respective ballast members 19, 21, 22 and respective contacts rl, r3, while in another position (dim) the coil is energized to insert resistors 18, 20 in series with the respective lamps and to change over the contacts r2so that the lamps are supplied with increased voltage from the auto-transformer 17 to maintain the stability of operation at low current densities. Capacitors 24, 25 reduce lamp shimmer in the dim condition and a resistor 23 prevents excess current should contacts rl, r3 fail to open. Interference suppression capacitors 26, 27 are connected so as to be effective in both conditions of the circuit. In an arrangement to supply a single lamp, Fig. 2 (not shown), the auto-transformer (17<SP>1</SP>) supplies the filament heating current and a third set of relay contacts (r<SP>1</SP>3) controls a power factor capacitor (28) connected across the supply terminals L, N. The circuit of Fig. 1 may be modified by connecting the members 19, 21, 22 in series with the respective contacts rl, r2 across respective resistors 18, 20 so that these members are out of circuit in the dim condition.
