Title: Plated through-holes for printed circuits
IPC: H05K3/46
Filed: 1975-10-15
Abstract: 1487800 Printed circuits INTERNATIONAL BUSINESS MACHINES CORP 15 Oct 1975 [31 Dec 1974] 42144/75 Heading H1R A green ceramic sheet is doctor bladed on to a moving resilient plastic or stainless steel substrate ribbon, and may comprise a mixture of alumina powder with a binder, e.g. of solvent, a humidifier, a plastifier, and an organic resin. After drying the film is stripped from the substrate and blanked into sheets of required dimensions which are mounted on carriers. Vertical through holes are punched, and a conductive metallized paste is silk screened in through a molybdenum mask also depositing part of a surface conductive pattern; the paste comprising molybdenum particles with glass grit mixed with a solvent and binder. Thereafter the ceramic sheet is stripped from the carrier, removing part of the paste from the through holes to leave a thin layer on the insides of the holes and on the surface of the sheet (Figs. 1c to 1d, not shown). Plural such sheets may be stacked with aligment of the through holes, compressed, and dried to form a monolith. The green coated sheets are then sintered, and the through holes may be filled with molten copper or soldered or brazed in copper pins for connection to external circuitry. Alternatively the metallized through holes may be filled with a cellulose or graphite paste so as to prevent sealing during lamination (Figs. 2a, 2b, not shown) which is burned off during sintering to leave a cavity 32 in the metallized lining of a through hole traversing several plates of a laminate (Fig. 2c). Then a pin 33 (Fig. 2d) of e.g. aluminium plated copper or copper alloy is centred into cavity 32 and brazed in at 34 using copper silver indium alloy. The molybdenum lining may be previously nickel plated. Semi-conductor chips may be attached to the reverse side of the module, which may have a protective cover.

Abstract: 919,379. Making electric lamp filaments. GENERAL ELECTRIC CO. Ltd. Nov. 29, 1961 [Dec. 8, 1960], No. 42299/60. Class 39 (2). A tungsten filament in the form of a helical coil, before incorporation in an electric incandescent lamp is threaded on a straight and substantially horizontal rod or wire of molybdenum or tungsten in an inert or reducing atmosphere and is heated by the passage of current along the rod to a temperature and for a time sufficient to cause recrystallization of the tungsten in the filament. A tungsten rod 2 is butt-welded to a molybdenum rod 3, one end of which is secured in a tube extending from a brass block 5 and provided with a gas inlet 7. The other end of the rod passes through a hole in a perforated plate 9 and is clamped to a terminal block 10 urged away from the plate 9 by a spring. The mandrel is surrounded by a silica sleeve 4, a mixture of hydrogen and nitrogen passed into the tube and the mandrel heated to 2000 degrees for an hour by the passage of an electric current. The mandrel is then cooled and the filament 1 threaded thereon. With a flow of gas as before, the filament is heated by the passage of current to 1950 degrees for 1¢ to 2 hours. To avoid overheating the ends of the filament, the sleeve 4 may be enlarged in the neighbourhood of the filament so that the velocity of the gas is greater adjacent the bare parts of the mandrel. Filaments so treated are stated to be specially suitable for use with a vitreous silica envelope.

Title: Tensiometer for measuring the surface tension of liquids
IPC: G01N13/02
Filed: 1960-12-22
Abstract: 915,917. Testing surface tension. FISCHER SCIENTIFIC CO. Dec. 22, 1960 [March 22, 1960], No. 44043/60. Class 106 (2). Apparatus for measuring surface tension of a liquid comprises means for supporting a container for the liquid; and a frame adapted at one end thereof to receive a rotatable shaft, a torsion wire being secured between an end of the shaft and the other end of the frame and having clamped to it a balance arm supporting at one end a ring, the plane of which is substantially horizontal and which can move through the liquid in the said container when the arm is pivoted by torsional rotation of the wire, means being provided for indicating the stress imparted to the wire by rotation of the said shaft. As shown in Figs. 1 and 2, a pillar 11, standing on a base 8 provided with a spirit level 10 and levelling screws 9, supports a frame 28 and has a sliding lockable collar 12 an arm 13 of which supports a boss 14. The latter threadedly engages a second pillar 15, supporting a platform 16 for the container 17, capable of fine adjustment by means of knob 19. Backlash is prevented by spring 20. Across the frame 28 is stretched a wire 27 extending axially through a rotatable hollow shaft 30 and clamped at its far end to a hub 32 rigid with shaft 30. Rotation is imparted to the latter from the drive shaft 35 of a motor 34 carried by frame 28 via a gear system including a rotatable shaft 37 having a worm portion meshing with a pinion 40 rigid with shaft 30. Shaft 37 may also be rotated manually by means of crank 68. Rotation of wire 27 causes pivoting of a bar 26 clamped to it (Fig. 4) and a ring 21 supported by a slidable collar 51 at one end of bar 26 can thus be moved through the surface of the liquid in container 17. The end of bar 26 is threaded and rotation of a nut 52 facilitates adjustment of collar 51 which follows nut 52 under the pressure of spring 53. A pointer 54 carried on bar 26 cooperates with a line 55a on mirror 55 fixed to a bracket 58 to allow setting of bar 26 to a zero position. A vernier 41 is fast with hub 32 and an idly mounted scale 42 can be brought into alignment for the zero reading by manual rotation (using knob 47) of a coacting idle pulley 44. When ring 21 breaks the surface of the liquid in an upward, or a downward direction, a contact 57 carried by bar 26 completes a lowvoltage circuit by touching a portion of wire 59 to energize a hold-on relay which breaks the motor circuit. The amount by which the vernier 41 has rotated indicates the torsional stress in the wire and hence the surface tension of the liquid.
