Patent ES-349649-A1 (ES)
Title: Improvements in and relating to Electronic Devices
IPC: H01L21/288
Filed: 1968-01-23
Abstract: Electrical contact to an electronic device such as a diode, transistor, or integrated circuit is made by evaporating a layer of aluminium on to the surface of the device, by forming a layer of elementary nickel on at least parts of the aluminium layer (by evaporation, by atomizing techniques, or by vapour deposition), and by electrodepositing metal on to at least part of the nickel layer. In the embodiment, aluminium is deposited over a silicon oxide or silicon oxide-boron oxide film, aluminium is etched away except from the vicinity of holes exposing the emitter and base region of a transistor, and the remaining aluminium is alloyed into the semi-conductor. An overall coating of aluminium is then applied followed by an overall evaporated nickel coating (obtained by passing a heating current through a nickel filament). The nickel layer is selectively etched to form a desired contact pattern and copper then electroplated on to selected parts of the nickel pattern to form raised areas for flip-chip bonding. The structure is completed by etching away that part of the aluminium layer which is not covered by nickel. Etchant compositions are disclosed for selective removal of one or both of aluminium and nickel from silicon oxide.

Title: Sack filling apparatus
IPC: B65B43/18
Filed: 1968-06-07
Abstract: Bag filling apparatus includes means to raise a flat bag to an opening position adjacent a filling spout, suction devices to open the bag by pulling apart the bag sides and a filling spout movable relative to the bag to enter the mouth. A stack of bags 8 enters the machine on a conveyer 9 and is checked by a stop beneath a suction cup 6 on a pivoted arm 2. The cup grips the bag and retracts and the arm pivots upwards until the cup is aligned with a further cup 12 adjacent a bag guide 10. The ends of the bag mouth are gripped by pairs of jaws 17, 18 on a carriage 15 running on rails 14 between the bag pick-up position and a filling position. The carriage supports also a filling spout 16. The cups move apart and the pairs of jaws approach each other so that the bag mouth is opened, permitting the spout to be lowered into it. The carriage now moves to beneath a hopper 48 and filling commences. During filling, the bag is supported by a conveyer 31 stationary in its normal direction of travel but vibrating to settle the contents and rising corresponding to diminution in height of the bag as it fills. After filling, the pairs of jaws move apart and then separate, thus flattening and releasing the bag mouth, the spout rises and gripper conveyers 34, 35 close in on the mouth to convey it to sewing means (not detailed) or a heater sealer. The conveyer 31 supports and moves the bag base until the weight of the bag is taken by a further conveyer beneath the sewing head. A single pair of cups 6, 12 may be used, but in a modification, Fig. 7, three pairs are employed, the central ones 51, 54 being joined to their reciprocating mechanisms but the others 50, 52, 53, 55 being supported from the cups 51, 54 by flexible plates 56, 57. As the cup assemblies part to open the bag mouth, stops 59 engage the plates causing the mouth to be opened to the shape shown.

Patent ES-359167-A1 (ES)
Title: Unitary combination of pressure-responsive flow control unidirectional valves for hydraulic systems
IPC: F15B21/00
Filed: 1968-10-15
Abstract: A double acting piston device (13) Fig.1 (not shown) has two parallel one way valves (18 and 19, 20 and 21) across each side and a fluid return pipe one operative to relieve excess pressure to this pipe, the other allowing fluid to flow into the cylinder if cavitation take place. An additional valve (22, 23, 24) vents the cylinder only if the combined pressure in each end exceeds a maximum set lower than the over pressure relief limit. A combination drive is symmetrically arranged, the pressure pipes from each side of the cylinder communicating at 15, 16 respectively and the return pipe to the reservoir joining at 17. On excess pressure piston 27 or 28 respectively retracts to a stop 29 and further pressure causes valve 32 or 33 to open against a strong spring 34 or 35. Low-pressure causes ball 42 or 43 to lift off its seating and admit fluid to the cylinder. If the combined pressure of the two parts of the cylinders exceeds the set maximum, both pistons 27, 28 will retract and eventually push rod 49 will engage balls 42, 43 and push them off their seating thus venting the system to the return pipe.
Patent ES-359832-A1 (ES)
Title: Flow pressure measurements
IPC: B29D5/06
Filed: 1968-11-02
Abstract: In an electromagnetic induction flowmeter (10), Fig. 1 (not shown) to monitor the flow pressure of a liquid metal, a resistance shunt 17 is provided on the exterior surface of the duct 13 to connect the electrodes 27, the resistance of which shunt is chosen to be equal to that of the path between the electrodes through the liquid metal. The dimensions of the duct are chosen so that the hydraulic pressure drop is low e. g. less than one per cent of the applied pressure, whereby the opposing pressure due to the induced current is approximately equal to the applied pressure. Thus the applied pressure is determined from the potential drop across the shunt which is a layer of copper or silver.
