[Class 124] In a method of forming glass lenses and like optical devices, a film of one ingredient of a glass attacking composition is formed on a glass blank and a film of another ingredient of the composition is formed on the surface of a mould which is a negative of the device to be produced, the blank and mould being then brought into contact to produce a glass attacking film on the high points of the blank. As shown, a glass blank 1, which may be roughly ground to the form required, held in a cooled support 9 has a film of sulphuric acid formed on it by a perforated pipe 62, and a mould 12 coated with platinum has a film of sodium fluoride deposited on it. The mould is brought into contact with the blank by a reciprocating movement and hydrofiuoric acid, which dissolves a small quantity of the glass, is formed at the points of contact. After the separation of mould from blank, the surfaces of both are cleaned by a blast of steam through the perforated pipes 71 and 75 and the process repeated until the blank assumes the form of the mould. The sequence of operations may be controlled by an electric motor 50 driving cams 54, 55 and 80. The sulphuric acid film may be formed on the mould and the sodium fluoride film on the blank.

Abstract: 1,199,660. Switching apparatus. B.K. SWITCHCONTROLS Ltd. 6 June, 1969 [19 June, 1968], No. 29161/68. Heading H2H. Apparatus for operating a contactor having auxiliary contacts is provided with means whereby the operating current for the contactor is reduced after the contactor has moved to its operated condition. Upon switching on an operating coil 15 of a contactor is energized from an A.C. supply 18, 19 by way of auxiliary contacts 14 on the contactor and a diode D1 during a half cycle of the supply when the terminal 18 is positive. In the next half cycle when terminal 19 is positive a circuit exists by way of a diode D2, resistor 16 and a capacitor 17. During this half cycle the coil 15 remains energized by the "free-wheeling" action of the diode D2. When the contactor is energized the contacts 14 open, the contactor remaining energized in succeeding half cycles either by way of capacitor 17 and resistor 16 or by the "free-wheeling" action of the diode D2. Thus the holding current for the contactor is reduced compared with the operating current and the current flowing in the coil is in the same direction irrespective of the A.C. supply half cycles.
