Title: Manufacture of magnetic discs
IPC: B05C11/08
Filed: 1975-12-16
Abstract: 1528037 Coating by rotation of substrate BASF AG 16 Dec 1975 [17 Dec 1974] 51403/75 Heading B2E In the production of a magnetic disc by applying to a base disc a dispersion of magnetic pigment particles in a solution of an organic binder in a solvent, rotating the disc to distribute the dispersion thereover, and drying and curing, the disc is rotated in the presence of means opposed to the surface being coated so that a column of air having a rotational speed approximating that of the disc is defined between the means and the surface. The means may be a flat or profiled covering disc of at least equal diameter to the base disc which is rotated therewith at a distance up to 20mm from the surface thereof. Two base discs may be coated and rotated simultaneously, each serving as a covering disc for the other. The discs may rotate in a horizontal or inclined plane and the coating may be applied by pouring or by spraying from radially movable nozzles whilst the base disc is slowly rotated. Suitable pigments and binders are listed; in an example an Al disc is coated on both sides with a gamma Fe 2 O 3 -alumina-epoxy resin-aldehyde resin dispersion.

Abstract: 1,117,369. Sets. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 Nov., 1966 [13 Dec., 1965], No. 52839/65. Heading H4J. A telephone instrument has a gravity switch comprising a contact assembly constituted by a snap action contact unit, e.g. a microswitch. In one embodiment (Fig. 1), the gravity switch comprises a microswitch 2, a sheet metal intermediate lever 4, a return spring 6 and a cradle lever 8. The lever 8 comprises two arms 10 extending from an integral bar 12 and is pivotally mounted at points 14 near the top of a frame 16 mounted on a base 18. The rear ends of the arm 10 have plungers 20 which may be fitted with plastics caps and protrude through holes in the instrument casing (not shown). Stops 22 limit downward movement of the arms 10. One arm 10 is formed with a projection 24 which engages an upper arm 26 of lever 4 to cause pivotal movement of the lever 4 about a pivot 28. The microswitch 2 has a contact operating plunger 34, a mechanism controlling a required number and arrangement of contacts and is mounted on a circuit board 36 on which other components (not shown) and wiring terminals 38 are also accommodated. A single fixing screw 40 is provided, positioning being maintained by co-operating notches 42 in the circuit board 36 and frame 16. Alternatively, the bell-crank lever (4<SP>1</SP>), Figs. 2A, 2B (not shown), is of cast or moulded plastics. Integral or integrated with the upper arm (26<SP>1</SP>) is a portion (50) constituting a housing for a return spring (6<SP>1</SP>) acting in compression between a fixed abutment on the cradle frame 16 and a tension adjusting screw (54) which screws into the portion (50). The sequence of operations is the same as that of Fig. 1. A reverse sequence of operations (i.e. microswitch ON when plungers 20 depressed and OFF when plungers 20 released) is obtained by providing the lever pivot (28<SP>11</SP>), Figs. 3A, 3B (not shown), higher and to the left of the microswitch plunger (34<SP>11</SP>). The lever (4<SP>11</SP>) is formed with a portion (58) joining its two arms (26<SP>11</SP>, 32<SP>11</SP>) and providing a lever arm for a compression spring (6<SP>11</SP>) acting between and abutment (60) and an adjusting screw (62). Alternatively, a cradle lever 8 (Fig. 4), includes an arm 10 with an operating plunger 20 and a downward projection 24. A reverse Z metal strip lever 70 is pivoted adjacent its lower end against a tongue 72 projecting forwards from a bracket 74 mounted on a microswitch 76. The bracket 74 has a portion 78 providing an anchorage for a torsion spring 80, the other end of which is hooked on to the middle of the lever 70. The upper end of the lever 70 is formed as a channel 88 (see also Fig. 5A, not shown), the sides of which co-operate with the projection 24. The lower part of the lever 70 bears on the microswitch plunger 90. The mioroswitch contact arrangement comprises two independent switch units, one a change-over unit (92), Fig. 6E (not shown), and the other a normally closed unit (94).

Abstract: 1535444 Lasers RAYTHEON CO 20 Dec 1976 [2 Jan 1976] 53024/76 Heading H1C The ring resonator of a rotational rate sensor has an even number of mirrors 12-22, Fig. 1, or 42-48, Fig. 4, in the optical path, the mirrors being so arranged that the electromagnetic field distribution of a circulated resonant beam is spatially rotated by #/2 radians for each complete passage of the ring. Due to this spatial rotation and the phase alterations effected by the mirrors, the resonator supports two oppositely directed resonant beams each having a circular polarization which is oppositely directed to the other and each of a different frequency. The resonator includes a laser active medium 24 in a magnetic field from an energized coil or magnet 30, the Zeeman effect so obtained producing a total of four resonant beams of different frequencies, two for each direction around the ring. The output beams from mirrors 20 or 44 may be used in a feedback path 40, 41 to effect resonator frequency stabilization. A suitable laser active medium may be a gas mixture comprising 8 <SP>3</SP>He + 0À48 <SP>22</SP>Ne + 0À52 <SP>20</SP>Ne.

A rotatable conical plug valve has a liner 55 of plastics material in which the plug 50 is seated. To prevent excessive build-up of pressure behind the liner, it is provided at two points 75 with pressure relief areas reduced to leave small diaphragm-like portions 80 which burst and relieve the excess pressure into the port 56 in the plug. The liner has enlarged portions 71 located in recesses 41 of the valve body. Upper and lower circumferential flanges or beads (30, 36), Fig. 1 (not shown), of the sleeve are also located in recesses in the body. Bearing on the upper flange and on the top face of the plug is an annular sealing diaphragm (62) which seals a stem (65) and is pressed down by a sleeve (67) and keeper (69). The liner is of fluorocarbon, resin e.g. P.F.F.E. The inlet 23 is larger than the outlet 24 and the plug bore is tapered so that the outlet end is first shut off.

Abstract: 1,199,848. Integrated circuits. MOTOROLA ..Inc. 22 Nov., 1968 [15 Dec., 1967], No. 55557/68. Heading H1K [Also in Division B3] Leads are attached to raised coplanar aluminium bonding pads 12 on an integrated circuit wafer 11 by aligning the free ends of leads 24 (Fig. 6) extending inwardly from a frame member 21 with the pads and bonding them thereto in a single step. This is effected without heating by sandwiching the lead ends between the block and an anvil 32 no larger than the block itself and applying pressure and transverse high frequency vibrations (60 kc./s.) to the assembly via bonding needle 33. The free ends 54 of leads extending inwards from a larger frame member 51 of heavier gauge material such as nickel, copper, steel or KOVAR (RTM) are then aligned with portions of the first leads and bonded to them. Parts of the first leads extending beyond the bonds are removed before or (as shown) after this last operation. A number of frames 21 are preferably stamped or etched from a continuous strip of aluminium or copper 2 mils thick so that they can be wound on spools and run through the bonding apparatus in a continuous process. The anvil 32, bonding needle 33 and the backside of the wafer are roughened to facilitate communication of vibrations from the needle to the bonding areas. Lateral spread of the end of each tapered lead 24 during bonding causes it to kink adjacent the bond into the recess 35 provided for the purpose so that the leads stand proud of the edge of the wafer. Although leads 24 may be soldered, brazed, or bonded by a thermocompression or ultrasonic technique to those of frame 51 it is preferred to form resistance welds using a cylindrical welding element (Fig. 8, not shown). If desired, before this operation, the wafer and leads are stuck to a supporting disc of ceramic (shown in phantom) with epoxy resin or between two such discs. Finally leads 24 are severed from the first frame with the aid of a cylindrical knife edge or by simply ripping away the frame. The resulting elements may be potted in resin or mounted in ceramic flatpacks before removal from the second frames.
