A method of forming and handling small sheet-metal parts comprises providing a strip of metal wider than the length of said parts, punching from said strip projections remaining integrally joined to said strip, punching said parts from said strip so as completely to separate the parts from the strip, returning said parts to the openings formed in the strip, coiling the strip so as to make the projections of one turn of the strip space the turn from an adjacent turn of the strip, subjecting the coiled strip to a liquid treatment, uncoiling the strip and successively pushing the parts from the strip at a work station. The method is described in relation to producing aluminium parts 1 inch long, 0À19 inch wide and 0À04 inch thick which are subsequently welded to nuclear fuel elements as spacing ribs. The steps of the method are indicated in Fig. 1 (not shown). Fig. 2 (not shown) shows a strip 10 which has had projections 12 formed thereon by a bending punch, Fig. 4 (not shown), and which has had triangular indentations 23 formed therein in positions corresponding to the ends of the parts which are to be blanked out. Fig. 3 shows the shape of the parts 29, the blanking punch cross-section 24, and a hold-down 27. Fig. 5 (not shown) shows a tool comprising the punch 24, a co-operating die 28, the hold-down 27 and a spring-loaded ejector 25. As the parts are blanked from the strip the ejector is depressed and as the punch 24 returns the ejector raises the blank 29 and returns it to the plane of the strip 10. The movement of the blank is limited by a shoulder 30 engaging a shoulder 31 in the die. The strip is subsequently coiled and the projections 12 space the coils apart. The row of projections along one edge of the strip project to one side and the row of projections along the other edge of the strip project to the other side. The strip is finally fed to a welding machine by a toothed wheel 17 which engages the projections 12 and which is driven by a step-motor 18. At the welding station the blanks 29 are pushed out of the strip and secured to nuclear fuel elements.

Abstract: 1,186,526. Integrated circuits. TEXAS INSTRUMENTS Inc. 15 Sept., 1967 [23 Dec., 1966], No. 42212/67. Heading H1K. A method of preparing an integrated circuit comprises the steps of: (a) forming a layer 4 of insulating material, preferably silicon dioxide or silicon nitride, on a supporting body 1 of silicon; (b) depositing single crystals 7 of silicon at a plurality of nucleation sites on the layer 4; (c) depositing a second layer 8 of insulating material on the surface of the layer 4 to cover the crystals 7; (d) depositing a substrate 9 of semi-conductor material, preferably polycrystalline silicon, on the layer 8; (e) removing the supporting body 1 by etching or lapping; and (f) forming individual circuit components in each of the crystals 7. The nucleation sites may be randomly distributed on the layer 4, their density being controlled by the deposition conditions or by exposing varying areas of the underlying surface of the body 1, or may be pre-selected by imprinting a nucleating agent on the layer or by forming indentations in the layer using mechanical means or an electron beam. In one embodiment, a silicon dioxide layer 4 15,000 Š thick, is formed by vapour deposition or thermal oxidation of the body 1 and the crystals 7 are formed by reacting SiCl 4  or SiHCl 3  with hydrogen at 1000-1300‹ C., suitable impurities being introduced into the reactor if required. The crystal growth is monitored through a microscope. The body 1 is removed with amine-catechol, and circuit components are formed in the crystals by ion implantation of appropriate impurities or by etching the layer 4 and diffusing or depositing suitable material. In a second embodiment having randomly distributed crystals, the locations of the crystals are recorded by scanning the surface and storing the information received in a computer. The computer may then be used to design a mask for selectively etching the layer 4 and forming the circuit components.

Abstract: 1402119 Voice frequency receivers; automatic exchange systems SIEMENS AG 13 Sept 1972 [14 Sept 1971 11 Nov 1971] 42459/72 Headings H4R and H4K A tone receiver includes a speech protection and tone frequency determining circuit which counts clock pulses during two consecutive half-cycles of a tone and only verifies the tone if the counts correspond within limits, the count for the first half-cycle or the complete cycle being used to indicate the tone frequency. The application is to two tone receivers, e.g. for push button dialling signals and one such circuit may be provided for each frequency band (Fig. 1, not shown) or alternatively one circuit is shared between the two frequency bands and is used consecutively therefor via a changeover switch (Fig. 4, not shown). In one circuit a forward counting counter RZ1-RZ4, Fig. 2, is used which is driven by clock pulses. Gates M1 and M2 define a range of counts in which the negative transistion should occur for a particular frequency and gates E1 and E2 define the complete cycle count longer for the same frequency, a signal being produced at output Q of bi-stable device FF4 if the half and fiull wave transitions occur in the correct count ranges. In practice a plurality of circuits DS are provided in conjunction with the counter, one for each possible frequency to be detected by the circuit. A second circuit uses a backwards and forwards counter, Fig. 3, and pairs of gates U1 O1 ... U4, 04 are used to define the half-cycle count ranges for a respective frequency to be detected. The speech protection is afforded by gates G1, G2 which define counts 125 above and below zero respectively. The counter is triggered by a positive going transition and for a valid frequency the count G1 should be passed through twice without the count G2 being passed. Fig. 5 (not shown), illustrates the modifications by way of additions to the arrangement of Fig. 3, where the same circuit is to be used consecutively for both frequency bands and assuming a 2 out of 8 code. Essentially two sets of bi-stable devices HSB are provided, and one set is enabled for each position of a changeover switch which couples outputs of one of the two clipped band passed waveforms to the circuit.
