Title: Electrical integrated circuit package
IPC: H01L23/495
Filed: 1972-02-23
Abstract: 1383297 Semi-conductor mountings PLESSEY CO Ltd 24 Jan 1973 [23 Feb 1972] 8257/72 Heading H1K A semi-conductor package is constructed from a sheet of, e.g. beryllium copper processed into a patterned frame (Fig. 1) wherein attach pads 1 are positioned along the sides of a square abcd and corresponding contacts 2 are arranged in rows extending parallel to opposite sides of the square and are connected over 3 to the contacts. A marginal band 4 encloses the contacts, and with the square abcd is eventually removed by cropping. Stubs 5 with locating holes 6 extend inwardly from the band 4. Pads 1 are dimensioned to register with conductive areas of an integrated circuit chip to be included in the package, and contacts 2 are dimensioned to register with contact areas of a printed circuit mounting board. The'contacts and pads are plated, e.g. with Au and shaped to present a double crested configuration (Fig. 4b) and the frame is bonded to an insulant cover 9 having windows 10 admitting crests 7, 8 with locating holes registering with holes 6, and bonded by lines e, f, g, h. The cover may be of plastic, ceramic, or coated metal bonded by epoxy adhesive or solder glass. An insulant base 13 (Fig. 3) of similar material has locating holes 15 and a central cavity 14, and is bonded at its upper face to cover 9 with the integrated circuit chip 12 received in the cavity and connected by contacts 2. After cropping marginal band 4 the package is as shown in Fig. 4b. A printed circuit board 16 (Fig. 4a) has locating holes 17 registering with holes 6, 11, 15 and carries contacts 18 positioned to engage crests 7, 8 of a conductor 2; the package being secured thereto by bolts and nuts through the aligned holes. Alternatively the frame may be bonded to the base before bonding on the cover, the chip is inserted in the cavity and secured by conductive adhesive or bonding to a fold layer of the base, and the attachment pads may be connected to the chip contacts by wire bonds; after which cover 9 is bonded on with recesses in the underside clearing the wires (Fig. 6, not shown). A thermally conducting fastener having two studs registering with the holes and carried by a strip may be moulded into the bore; the studs replacing the bolts to secure the package, while the fastener is epoxy or eutectic bonded to the chip to dissipate heat. Alternatively the chip may be encapsulated with the fastener strip in a plastic moulding. In a modification (Fig. 6, not shown) the cavity may penetrate the entire thickness of the base as a circular tapered aperture, and the conductors may be cranked to lie in a depression of the base surrounding the aperture, in which a spacer supports the attach pads. The chip is positioned on the undersurface of cover 9 with conductive areas on its lower face connected by bond wires to the attach pads. The aperture is closed by a lid at the underside of the base.

Title: Improvements relating to control apparatus for winding gear
IPC: B66B1/12
Filed: 1935-03-16
Abstract: 448,575. Brakes for winding-apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd., 1, Kingsway, London.-(Smith, D. M.; c/o Metropolitan-Vickers Electrical Export Co., Ltd., P.O. Box 3633, Johannesburg, South Africa) March 16, 1935, No. 8258. [Class 78 (v)] [See also Group XXXIV] Control equipment for fluid-operated brakes for winding-gear comprises a main brake control valve governed by a deceleration governor and means for changing over from this valve to an auxiliary control valve in an emergency, the auxiliary control valve being governed by a separate governor. The changeover valve 9 is connected with the cylinders of the main and emergency control valves 1, 7 by pipes 11, 22 respectively, and in the normal operating position the plunger 13 is held up against the pressure of the spring 14 by fluid pressure in the space 15 and puts the pipe 11 into communication with the pipe 12 leading to the brake engine. The space 15 is connected to the pressure conduit 5 through the trip valve 10, the plunger 16 of which normally is held up by a solenoid 18, but falls under the action of a weight 17 when the current through the solenoid is interrupted. In the latter position the pipe 19 leading from the space 15 is in communication with the exhaust pipe 21, and the plunger 13 falls, thereby putting the pipe 12 into communication with the pipe 22. The brakes are thus applied at a rate which is limited by the action of the deceleration governor 8. If the rate of deceleration is excessive, the governor 8 will raise the plunger 23 and the braking will be eased. The valve 1 may be of the kind described in Specification 392,252, and is provided with a manual or pedal control 2, an emergency trip 3, and an inertia governor 4. The valve 10 may be tripped either by an attendant, or by a secondary overspeed trip set for a higher speed limit than the primary overspeed trip. An interlocking arrangement may be provided to prevent resetting of the change-over valve until the pressure at the main control valve outlet corresponds with the pressure normally existing there when the brakes are applied.

[Class 68 (ii)] Ship salvaging apparatus comprises a pair of spaced barges or floats F spanned by overhead girders B which carry hoisting tackle H and are maintained level in spite of relative vertical movement of the barges due to wave motion. The girders are supported in towers T carried on turntables 11 operated by motor driven screw-gearing 12, the ends of the girders being slidable against adjustable dash-pots 48 in carriages 22 slidable vertically in guides 20 on the towers. The carriages are each supported on three plungers 28, 37, shown in section in Fig. 6, operating in hydraulic cylinders carried on a platform 18. The plungers 28 which are used to compensate for unequal distribution of the weight of the ship, each operate in a cylinder 27 in communication with liquid to a cylinder 31 the upper portion of which is supplied with air under pressure. The pairs of plungers 37 form part of the self levelling arrangement, corresponding cylinders 36 at each end of a girder being in communication to conipensate variations in level between the barges and all the cylinders on each barge being in communication to compensate pitching. The hoisting tackle is operated by a winding drum 16, the cable being passed under a jockey roller on a lever 60 connected by a link to the girder carriage so as to compensate for variation of the height of the girder relative to the barge. The girders may be fully raised if the ship is in danger of fouling them. The parts of apparatus are readily dismountable.

Title: Improvements in electrical relays or contact makers for mine signalling apparatus and for other purposes
IPC: B66B19/06
Filed: 1919-04-05
Abstract: 139,055. Allott, J. R. L., and Dean, E. April 5, 1919. Switches; actuating. - A switch for use with electric signalling-apparatus, especially in connexion with colliery winding, to close the circuit of an electrically-operated signal and to cancel the signal, consists of a contact-maker actuated by the revolving of paddles, vanes, or propellers immersed within a bath of oil. In the construction shown in Fig. 1, a spindle C, journaled within an extension B<1> of the cover B of a tank A containing oil, carries an insulated slip-ring G with which a spring-pressed brush J engages. The slip-ring carries insulated contact blades H provided with contact points I normally in engagement with similar contact points in lateral extensions of the slip-ring. The spindle carries lateral arms extending between the contact blades and supporting paddles F dipping into the oil, so that they may hinge about the arms. When the spindle is rotated by means of the pulley E, the resistance of the liquid causes the paddles to move towards the surface of the liquid, and a cam N on a boss of the paddle first comes into engagement with both of the blades, as shown in Fig. 3, and completes the circuit through the spindle to the cam and so through both of the blades to the projection of the slip-ring, which is engaged by the brush. With increase of speed of the spindle, the paddles rise to the horizontal position, and the cams separate the contact blades from connexion with the lateral projections on the slip-ring, as shown in Fig. 4, thereby breaking the signalling-circuit again. As the spindle slows down, the circuit is made again moment. arily to cancel the signals indicated during the winding. In a modified construction in which the spindle is rotated by a hand-operated cord passing over the pulley and returned by a weight, fixed semicircular contacts are mounted on the underside of the cover and are engaged, when the speed is adequate, by contacts mounted on opposite sides of the insulating-paddles.
