Title: Improvements in and relating to road rollers
IPC: E01C19/26
Filed: 1948-08-31
Abstract: 652,958. Land rollers. SOC. ANON DES ANCIENS ETABLISSEMENTS ALBARET. Aug. 31, 1948, No. 22981. Convention date, Sept. 25, 1947. [Class 6(i)] Initial resistance to the movement of a motor-driven ground roller is overcome by connecting the driving-motor to the roller through epicyclic gearing carrying a counterweight 19. This, while the roller remains stationary due to sinkage in the ground, swings up and overbalances the roller about its point of contact. Abutments 21 on the fixed axle limit the rise of the weight 19. Instead of epicyclic toothed gearing, the live axle of the roller may be geared by chain and sprocket gearing to a cylindrical weight which runs in guides in the roller against spring action. A hydraulic motor within the roller may be used. Twin rollers may be actuated through differential gearing.

Title: Masking techniques for use in fabricating microelectronic components and articles produced thereby
Inventor: KEENE CARL EARL
IPC: H01L23/498
Filed: 1971-04-19
Abstract: 1285525 Printed circuits; resistors; capacitors; semi-conductor devices HUGHES AIRCRAFT CO 19 April 1971 [9 March 1970] 23506/71 Headings HlK HIM HlR and HIS Microelectronic devices have layers with tapered openings produced by vapour deposition round a mask held a short distance from the substrate. A printed circuit cross-over between conductors 14 and 18, Fig. 6, on an alumina, beryllia or glass eubstrate 12 is formed by vapour depositing Mg and Al layers 28, 30 overall. An etch resist 40 is silk screened or photographed where connections are to be made to conductors 14, 18 and the layers 30 and 28 are successively etched with deliberate undercutting to produce "mushroom" masks 50<SP>1</SP>, Fig. 9. Glass or polyethylene terephthalate is then vapour deposited from a distant source to form a layer 20 which owing to the tendency of the vapour molecules to diffract round the edges of the mushroom crown, forms holes with tapered edges over the conductors 14, 18. The mushrooms are then removed by completely etching away the Mg pedestal and the connection 22, Fig. 12, between the conductors is made by evaporating on a layer of Al or Au and etching it to the required shape. The method may be used to produce an array of capacitors by depositing a thin layer of glass before applying the Mg layer 28. The conductor then does not connect with conductors 14, 18, but a capacitor is formed therebetween. The method may be used to make connection to the gold contacts of thick film Nichrome (Registered Trade Mark) resistors formed by the selective removal of deposited Nichrome by repetitive oxidation with potassium permanganate and the removal of the oxide with sodium thiosulphate. A plurality of resistors may be formed at several levels with through connections between the levels. The substrate may be a silicon or germanium semi-conductor device such as a flip-flop. Instead of using glass, layer 20 is formed by sputtering with silicon and the device is mounted on a heat sink and heated to 340‹ C. so that the silicon oxidizes. The pedestal of the mushroom mask is made of copper instead of magnesium. In a modification, the magnesium and aluminium layers 28, 30 may be replaced by two different photoresist materials.
