In a method of manufacturing a printed circuit board, conductors 12, 14, 16 are formed on the surfaces of an insulating substrate 10, holes are formed through the substrate where required, a thin conductive film 22 is deposited on the surfaces of the substrate and conductors and on the walls of the holes, portions of film 22 are coated with a plating resist 24, and the uncoated parts including the walls of the holes are electroplated with metal 28, 30. Subsequently, resist 24 and the underlying parts of film 22 are removed. Preferably, conductors 12, 14, 16 are produced by the selective electrolytic deplating of a double-sided copper-clad epoxy glass substrate, in which holes have previously been punched or drilled; alternatively, the holes may be formed after the conductors; and the conductors may be produced by chemical etching. The conductive film 22 is preferably a thin semi-transparent coating of copper applied by an electroless plating technique. Resist 24 is applied by printing, stencilling, or silk-screening, and, after the electrodeposition of metal 28, 30 from a copper-plating bath, the resist is removed as by trichloroethylene.

Abstract: 1410477 Automatic control of speed INTERNATIONAL STANDARD ELECTRIC CORP 1 Dec 1972 [3 Dec 1971] 55472/72 Heading G3R [Also in Division H2]  A series motor M is connected to an A.C. supply through a triac T 1 which receives triggering pulses from trigger diode D3 when capacitor C2 has charged to a given level. The charging time of the capacitor is varied by a semi-conductor device T2 controlled by a voltage proportional to motor current and derived from resistor R2. In the arrangement shown the motor back e.m.f. sets the charging voltage across capacitor C2 and this is modified by the voltage proportional to current developed across R2 by causing the field effect transistor T2 to charge its conductivity. The control is arranged to operate only on one half cycle of the supply and to measure the load current during the other half cycle. This is achieved by the use of time constant circuit R1, C1.

Abstract: 1413668 Vehicle wheel covers E E FOSTER 7 Dec 1972 [27 Dec 1971] 56451/72 Heading B7C A wheel cover is detachably mounted on a wheel by means of elements on the inboard side of the cover disc which engage a surface of the wheel and at least one of which can be moved manually to a disengaged position to facilitate detachment of the cover. In a first embodiment (Figs. 2 and 5) a plastics cover disc has a peripheral flange 12 to which a reinforcing metal ring 26 and three equi-spaced substantially U-section spring elements 24, e.g. of steel are attached, e.g. by rivets. When the cover is applied to a wheel, edge portions 36 of the elements are cammed by the axially outer portion of flange 22 into engagement with the radially inner surface of the flange. Removal of the cover is effected by insertion of a tool 46 into any one of the pairs of notches 42, 36, and appropriate pivoting of the tool. In a modification (Fig. 9, not shown) the spring elements are substantially rectangular in section. In a second embodiment (Figs. 11, 12) three spring elements 68, 70 are provided, with only one (70) being manually movable. The elements are similar with element 70 being additionally provided with a tab 82 having an aperture 84. Mounting of the cover on a wheel is effected in a manner similar to that of the first embodiment, and removal is effected by using a tool (90) (Fig. 15, not shown). In a third embodiment (Figs. 19 and 21), the cover includes two spring elements 104 and a third element 106 (Fig. 20), the latter being provided with an aperture 122 in register with aperture 124 in reinforcing metal ring 26 and aperture 128 in the cover disc, and with an aperture 126 slightly radially outwardly displaced from those other apertures. Removal is effected by inserting a tool into the apertures and pivoting the tool to move the edge 116 radially inwardly. The cover is pivoided with a key operated bar (134) (Fig. 16, not shown) movable into a position in which its free end prevents insertion of the tool into the apertures 122, 124 and 126. In a modification the apertures are such that the edge 116 is moved radially inwardly by rotating the inserted tool about its axis (Fig. 24, not shown). In a fourth embodiment (Fig. 27) at least two spring members are provided, and each member includes radially outwardly and radially inwardly directed projections 164 engaging surfaces 86 and 150. Rotation of a tool extending through apertures 169, 170, 172, 174 causes the projections to be retracted from the surfaces.
