Abstract: 1,170,937. Making ball-pen points; stamping; punching; extruding. REAL PATENTAUSWERTUNGS ANSALT. 7 Dec., 1966 [8 July, 1966], No. 54795/66. Addition to B3P. Headings B3A, B3P, B3Q and B3W. A ball-pen point is made from wire by shearing a cylindrical workpiece from the wire, extruding the workpiece into a cylindrical tubular portion or a cylindrical tubular portion connected to a truncated conical portion, successively stamping and drawing the workpiece to gradually reduce its diameter and lengthen and shape it and finally forming the ball seat, placing the ball in the seat and rimming the edges of the seat to hold the ball in position. The wire is preferably brass or copper and is sheared by dies (3), (3<SP>1</SP>), Fig. 1 (not shown), and the workpiece is extruded into a tubular portion (10), Fig. 3 (not shown), by a punch (7) and die (8) and either its base (11<SP>1</SP>), Fig. 5 (not shown), is punched out by die (14) and punch (13) or the workpiece is shaped into a cylindrical portion (18), Fig. 4 (not shown), connected to a truncated conical portion (18<SP>1</SP>) by a punch. In the first embodiment the tubular portion (10) is cut to the desired length and placed in a bush (20), Figs. 7-12 (not shown), on an indexing turn-table which moves the portion under successive dies (19), (22)-(26) which shape the portion. In the second embodiment the tubular portion (18) with the truncated conical portion (18<SP>1</SP>) is placed in a bush 20 on an indexing turn-table and shaped by a series of dies, Figs. 19-22 (not shown). The shaped workpiece of both the above processes has the ball seat (35), Fig. 13 (not shown), and the ink channels (37), Fig. 15 (not shown), formed in subsequent steps on the turn-table. The ball (38), Fig. 16 (not shown), is held in position by rimming the edges of the seat, Fig. 18 (not shown), while the workpiece is held in the bush.

Abstract: 1,247,059. Hybrid circuits; D.C. signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Nov., 1968 [28 Nov., 1967; 28 May, 1968], No. 55879/68. Headings H4K and H4R. A hybrid circuit allows D.C. signals of either polarity to be transmitted from a source V to a load Z 1  via lines a, b and signals from the load Z 1  to be received by receivers M1 or M2, according to the signal polarity, while preventing the outgoing signals from V influencing the receivers M1 and M2 even though the load Z 1  may not be exactly balanced by the balancing impedance Z 2 . The circuit operates by providing a bridge circuit of impedances R, r, Z 1 , Z 2 - R<SP>1</SP> and r<SP>1</SP>, with the receivers tapped between points of nearly equal potential, e.g. A 1  and B 1 , and the signal from the transmitter applied on one side or the other of the resistors r and r<SP>1</SP> such that the potential developed across the receivers is of opposite polarity to that required to actuate them. In one embodiment Fig. 4 (not shown) the resistors R, r, R<SP>1</SP> r<SP>1</SP>, are formed by windings on a polarized monostable relay. Alternative embodiments in which separate transmitters are utilized for the transmission of signals of respective polarity are described with respect to Figs. 3a and 3b (not shown). The balancing network may be allotted different values in accordance with the signal polarity by connecting two different balancing impedances via respective oppositely polarized diodes.

Abstract: 1,157,570. Making caps. THOMASSEN & DRIJVER-VERBLIFA N.V. 11 Dec., 1967 [22 Dec., 1966], No. 56251/67. Heading B3A. [Also in Divisions B8 and F2] A metal screw cap e.g. of aluminium or tinplate for a container, e.g. a glass jar or bottle, whose neck has externally threaded portions of predetermined pitch, has a cylindrical rim 2 whose lower edge is curled inwards and upwards at 4, the curled portion having screw-threaded regions 8, 9 corresponding with those on the container neck. Each screw-threaded portion of the cap has a section over which the pitch is reduced and resilient deformation of these sections on applying the cap leads to a greater resistance torque enabling the use of a shorter rim 2 than would be necessary in a conventional screw cap. Making the screw cap.-The lower edge 3 of a deep drawn cylindrical cap is slightly deformed inwards, Fig. 2a (not shown), e.g. by means of forcing rollers; it is then formed with a curved portion 4 of substantially circular section, Fig. 3a (not shown), e.g. by means of a curling punch, and a punch is used to reduce the radius of curvature of the lower portion 5 of the curled portion 4 in order to form a rigid lower edge which prevents distortion of the cap during thread production. Three threaded portions are formed by means of a radially expanding forcing device subdivided into three sectors, the radial gaps between sectors meeting the undeformed part of the threaded portions, the cap being supported in a close-fitting die during the process.

Abstract: 1328128 Television HUGHES AIRCRAFT CO 11 Dec 1970 [11 Dec 1969] 58966/70 Heading H4F Apparatus for scanning an object comprises a hollow mirror prism 30 having mirrors on the outside and inside, the light from the object being reflected from one of the outer mirrors 30a through a lens system 36 to a transducer 38 which may consist of one or more photocells or infra-red detectors. The output from the transducer 38 is fed to a cathode-ray tube 50 and a light source 40. The mirror prism 30 is rotated to produce the line scanning and each mirror, e.g. 30a is tilted relative to the adjacent mirrors to provide the frame scanning, one or more frames being scanned during each rotation of the mirror prism 30. The light source 40, which may be a lamp or diode, directs a modulated light beam on to mirror 30a<SP>1</SP> mounted back to back with mirror 30a then via fixed mirrors 44, 46 and a lens 48 to the viewer. If an undistorted image (where the aspect ratio is maintained) is required mirror 30a<SP>1</SP> is mounted parallel to mirror 30a or at the same angle to the rotational axis of mirror prism 30 as mirror 30a, to produce a wedge-shaped configuration. If however a distorted image is required the mirrors 30a, 30a<SP>1</SP> are mounted at different angles. In an alternative embodiment (Figs. 1-3, not shown) a solid mirror prism is used, the light from the reconstructing light source, which may be an array of lamps, being shone on to the mirror on the face of the prism opposite to the scanning face, the associated reconstructing and scanning mirrors again being parallel to each other, at equal angles to the axis of rotation, or, for a distorted image, at some other angles. Instead of using one solid mirror prism, two identical prisms may be used mounted on a common rotational axis, one prism being used for scanning and the other for reconstructing (Fig. 4, not shown).

The unreacted part is then reduced to metal. The ceramic may be Al 2 O 3 , SiO 2  or alumino silicates and the coating powder may be Cu, Cu/Ag, Cu/Au, Cu/Al, Cu/Ni, Ni, Fe, Pb, Sn, In, Cd, copper oxide or copper chloride. Cu containing coatings may be heated at 1235-1250‹C in air and the oxide is reduced by heating to 300-400‹C in 90N 2 -10H 2 . Alternatively reduction is effected by dipping in molten Al or Zn or H 2 SO 3  or by electolysis in acidulated water. The fused layer may be overcoated with pastes containing Au, Pd/Au or Pa/Ag prior to reduction. The process is used for producing strongly bonded printed circuits or for forming ceramics.
