Abstract: 1,186,890. Semi-conductor devices. MOTOROLA Inc. 12 June, 1967 [13 July, 1966], No. 27058/67. Heading H1K. A semi-conductor device is mounted on a plate and is encapsulated with plastics material so that the plate forms one face of the encapsulation, the plate and the encapsulation having an aperture extending therethrough, the arrangement having lead members, one of which is integral with the plate, extending from the encapsulation in a plane parallel to, but offset from, that of the plate. As shown, Fig. 6, the leads 18, 23 and 24 and the plate 12 are formed integrally together with supporting strips 53 and 55 from a sheet of copper plated with nickel. The plate 12 is formed as an extension of the centre lead 18, and the ends of the two outer leads 23, 24 are flattened to form bonding areas 27, 28. As shown, Fig. 2, a silicon transistor die 26 is mounted with its collector region in contact with plate 12, the emitter and collector electrodes are connected by fine wires (34, 35) to bonding areas 27, 28, and epoxy resin is transfer moulded over the top of the plate to encapsulate the ends of the leads 23, 24 and the die 26. The leads are then separated from supporting strip 53 and the parts of strip 55 between the leads are also removed. Plate 12 has side members 21 which extend into the encapsulation 14 to improve the adhesion, and has an aperture 31 which is aligned with an aperture 33 in the encapsulation 14 so that the device can be bolted to a heat sink. The leads lie in a plane offset from that of plate 12 so that they do not contact the heat sink. A plurality of devices can be sequentially mounted and connected and then simultaneously encapsulated by forming a plurality of sets of leads structures connected together by the supporting strips (53, 55), Figs. 3, 4 and 5 (not shown). Strip 53 is provided with groups of apertures 54 by means of which the strip can be moved through assembly machinery.

Abstract: A moulded case low voltage circuit breaker for high currents has no arcing contacts and is equipped with arc blow-out means drawing the arc very quickly away from the contacts. An insulating shield associated with the moving contact forms an arc formation chamber of a small volume which is open in the direction of the arc chute. The moving and stationary contacts are fitted with arcing horns constituting a small divergent path in proximity to the contacts favoring rapid displacement of the arc, this divergent path leading to an area defined by a hump of the horn. In this area, the clearance of the arcing horns is smaller than the clearance between the contacts as soon as the latter separate to avoid any rearcing on these contacts.

Abstract: Aqueous suspensions of papermaking fibres and filler are each separately treated with an anionic or a cationic polymer, after which the filler (preferably) or the papermaking fibre is treated with a polymer of opposite charge to that used in the initial treatment. The filler and papermaking suspensions are then mixed to form a papermaking stock, with dilution as necessary before, during or after the mixing operation. This stock is then used to form a loaded paper web in conventional manner. The initial treating polymer is preferably a papermaking retention aid or flocculant, e.g. a cationic polyacrylamide or an amine/amide/epichlorohydrin copolymer in the case of cationic materials or an anionic polyacrylamide in the case of anionic materials. The further treating polymer is preferably an anionic or cationic starch, depending on the charge of the initial treating polymer.

Abstract: First and second field type detectors for first and second video signals have outputs indicating whether the video signals have first or second field types. The first video signal is synchronized with the second video signal for a combined display by a synchronous field memory and an asynchronous multiple line memory. The field type of the second video signal is changed when necessary to match the field type of the first video signal to maintain interlace integrity in the combined display. A field type changing circuit, which controls the synchronizing, has a first mode of operation which delays writing a current field of the first field type by one horizontal line period, a second mode of operation which advances writing a current field of the second field type by one horizontal line period and a third mode of operation which maintains a current field type. A comparison of the field type of the second signal to the field type of the first signal results in an output signal indicating one of a plurality of comparison outcomes, wherein the first and second video signals have the same field type, wherein the first video signal has the first field type and the second video signal has the second field type and wherein the first video signal has the second field type and the second video signal ha the first field type. A plurality of selectable interlace correction signals are generated, each being appropriate for one of the plurality of comparison outcomes.
