Title: Improvements in or relating to wires and their method of manufacture
IPC: B23K35/02
Filed: 1958-06-18
Abstract: 838,578. Making composite wire; soldering; riveted joints. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 18, 1958 [June 21, 1957], No. 19507/58. Classes 83 (2) and 83 (4). A wire for mechanically and electrically connecting parts which are disposed on opposite sides of an insulating support, while connection to at least one of the parts is established by soldering with an accurately predetermined amount of solder, comprises at least two bodies in the cross-section, at least one of which is made of a material of high electrical conductivity, while the remainder of the cross-section of the wire is occupied by solder, the melting point and shape of the bodies being such that even after the solder has melted the bodies remain stable in position relative to each other. A composite wire, Fig. 1, comprises two copper wires 1 and 2 and a remainder of soft solder 3. The wire may alternatively have three copper strands. A three-strand wire, Fig. 3, includes a solid copper wire 8 and two copper tubes 9, 10 filled with a powder or paste flux 11. In a modification the strands may be of silver, aluminium or steel. The wire is made by passing the strands of circular cross-section, after cleaning, through a bath of liquid soft solder, the wire emerging from the bath into a tube of internal diameter equal to the required external diameter of the wire. The length of the tube is so proportioned, according to the wire shape, bath temperature and the rate of passage, that the solder is solidified, after which the wire is drawn down to produce the forms of Figs. 1 and 3. It is stated that the strand wires need not initially be of circular cross-section; and the drawing die aperture may alternatively be rectangular, elliptical or of irregular shape. The wire is used to connect a part 28, Figs. 6 and 8, to a printed coil 26 on the opposite side of an insulating support 25. A short length 30 of the wire is inserted in an aperture 29 in the support 25 to pass through the part 28 also, the two ends of the wire being compressed by rams 31 to form a riveted joint. The rivet is then heated e.g. by a soldering iron and the solder portion of the rivet, which is of predetermined amount, is drawn out to complete a soldered joint, leaving the copper, silver, aluminium or steel strands in undisturbed relation. Flux is either provided by the tubular strands of Fig. 3 or may be separately applied. The rivet may be heated at the lower end only, the solder rising by capillarity to make the joint above the support, thereby protecting the coil from direct heat. Heating and compression of the wire 30 may be effected simultaneously. In a modification the ends of the wire may be flanged with a flanging mandrel. In a further modification rivets may be preformed from the composite wire one end only then being compressed after assembly. It is stated that connection may be established using heating only, i.e. without the use of compression or flanging.

Filed: 1938-07-01
Abstract: 516,627. Glass manufacture. DICHTER; J. July 1, 1938, No. 19567. Convention date, July 1, 1937. [Class 56] Relates to machines of the kind described in Specification 467,282 for forming test-tubes, tablet tubes, and like containers from glass tubing by parting a length of tubing into two smaller lengths which are shaped by inflating the heated ends against moulds. According to the present invention, blow-heads which engage the open ends of the' small tubes are moved inwards towards one another and thus move the tubes into contact with the moulds. The tubular glass blank is supported on, and rotated by, pairs of discs 2 and is cut into two smaller sections 27, and bottoms formed on the sections, by the flames from the burners, as described in the prior Specification. Counterpressure rollers 38 rest on the tubes 27 and force them into contact with blow-heads 101 which are rotatable on bored guide bars 102 through which compressed air is applied to the interiors of the glass tubes. The bottom-forming plate or mould 126 is raised to, and lowered from; the glass tubes 27 by a lever 131 rocked by a cam, and the blow-heads 101 are moved simultaneously to and from the moulds by bars 113, 114 turned in opposite directions by a gear wheel 115 oscillated by a cam. The holder of the mould is bored with a passage through which air can be blown to cool the holder and the mould. The surface of the mould may be grooved to allow air to escape and to prevent too rapid cooling; Letters or other markings can be formed on the glass by an .impression roller 138, Fig. 8, which is resiliently pressed into contact with the hot, plastic glass as it is shaped.

Title: Improvements in or relating to time-base circuits employing transistors
Inventor: ATTWOOD BRIAN ERNEST
IPC: H03K4/80
Filed: 1961-06-01
Abstract: 924,260. Semi-conductor oscillating and sawtooth producing circuits. MULLARD Ltd. June 1, 1961, No. 19810/61. Class 40 (6). In a time-base circuit for use in a magnetic beam deflection system, e.g. in a television receiver, wherein a transistor-amplifier output stage includes a clipping diode Dv, Fig. 2, and a capacitance Cv connected in parallel with a voltage dependent resistive element Rv between the diode and the D.C. collector supply so as to provide a stable voltage point Pv, the charge network R2, C2, C3 for providing the sawtooth drive for the transistor is supplied from the point Pv so as to stabilize the drive in amplitude against changes in the collector supply. As shown, the charge network is periodically discharged by an oscillator circuit employing a four-layer semi-conductor device O together with the elements R1, C1, R3 also fed from the table voltage point in order to improve frequency stability. Winding LS on the choke LC provides feed-back to the charge circuit to linearize the waveform. A transistor blocking oscillator, Fig. 3 (not shown), employing a negative temperature coefficient resister as described in Specification 896,024, can be used instead of the four-layer circuit shown. The resistive element Rv may be a Zener diode. The use of the diode Dv enables the flyback voltage to be reduced almost to the theoretical value required to reverse the scanning current with only small changes in the peak voltage due to variations in the supply voltage. The conduction of the transistor is also reduced with consequent reduction of transistor dissipation.
