Abstract: 1,218,630. Adders and radix converters. INTERNATIONAL BUSINESS MACHINES CORP. 6 Nov., 1968 [15 Nov., 1967], No. 52477/68. Heading G4A. A binary adder comprises a plurality of binary adder stages (e.g. each as in Fig. 1), each having a plurality of bit positions (e.g. 4) for simultaneously adding a plurality (e.g. 6) of binary inputs I to each of the bit positions and including a plurality of super adders SA (e.g. upper row in Fig. 1), each super adder being associated with one of the bit positions and having a first order output S which represents the output sum for the respective bit position and a plurality of higher order outputs C 1 , C 2  representing different order carries, and carry determining means (e.g. the lower row of super adders SA, half adders HA and full adders FA in Fig. 1) for generating carry inputs to the super adders and to the next binary adder stage from the higher order outputs mentioned above and carry inputs from the preceding binary adder stage. Each super adder may use 4 full adders (Fig. 3A, not shown), or a summing amplifier feeding an A/D converter. Fig. 8 (not shown) shows a parallel BCD adder using one of the above "stages" in each decimal order, sum and carry bits from it being combined in a correction and output circuit (Fig. 7, not shown) for the order, which circuit utilizes logic to calculate correction bits and half adders and full adders to calculate the corrected BCD output for the order and carries to go to the "stage" of the next higher order (if any, or to the BCD output if none). A BCD adder as above can be used for binary to BCD conversion by feeding each bit of the binary input to adder inputs corresponding to its BCD equivalent.

Title: Improvements relating to inverter circuits
Inventor: BERMAN LAWRENCE JOHN
IPC: H02M7/06
Filed: 1968-11-08
Abstract: 1,271,951. Static inverters. INDUSTRIAL INSTRUMENTS LTD. 3 Nov., 1969 [8 Nov., 1968], No. 53110/68. Heading H2F. An inverter circuit comprises two bi-phase inverters 1, 2 (Fig. 1), separately fused and each capable of supplying the full load connected to terminals 5, 6 of a common output circuit and each including a push-pull pair of SCRs 1, 2 and 3, 4 respectively and a constant voltage transformer CVT1, CVT2 respectively, the primary and secondary windings in a transformer being selectively loosely coupled to one another due to magnetic shunts in the cores. Normally the inverters are fired in synchronism e.g. from a common trigger circuit or a common oscillator feeding two separate trigger output stages. SCRs 1 and 3 are fired together to provide one half cycle of output while SCRs 2 and 4 are fired together to provide the other half cycle. Each inverter supplies about half the load.  Assuming a fault condition in which SCR1 fails to turn off when SCR2 is fired, due to miscommutation or short circuit in SCR1. The core of CVT1 starts to saturate because of the continuation of current in SCR1 and the impedance of the primary collapses causing further increase in current. A current limiting choke L1 eventually becomes saturated also, until finally the increasing current blows fuse FS1. The inverter 2 then takes up the full load. A 'flywheel' effect of stored energy in the two secondaries and in capacitors C4, C5 prevents the interruption of the load voltage due to the short circuiting of the primary by SCR1 and SCR2. In addition inverter 2 is not overloaded since it is isolated from the short-circuit by the loosely coupled transformers. In place of the two transformers there may be two primaries and a common secondary, wound on a common core with magnetic shunts Fig. 2 (not shown). Since CVT1 will still be energized via its secondary when the fuse blows diodes D5, D6 are provided to prevent short circuit currents in the primary. Capacitor C1 is for commutating. Failure of an inverter may be indicated by an alarm.

Abstract: 1,184,962. Blow-moulding; articles with inserts. K. NAKAMURA. 22 Nov., 1967 [30 Nov., 1966; 11 Dec., 1966 (3)], No. 53226/67. Heading B5A. In the blow-moulding of articles having inserts, e.g. a preformed neck portion, the insert is carried by holding means to a pre-treatment station where the insert is fused or softened and then inserted into an opening in the mould so as to be flush with the opening, which is closed by the insert and the holding means. As shown in Fig. 7, holding means 26 guided on rails 36, by means of cylinder 25, conveys the insert to solvent-applying means 28, to swell the plastics insert and heating means 29 to soften it before being positioned in hole 23 in the mould 6. A parison (3, Fig. 1, not shown) is continuously extruded, the end is closed by means (4), which then move upwardly with cutting and holding means (11, also Fig. 4, not shown) which cut and hold the parison (3) and the parison is preblown through nozzle (21<SP>1</SP>). Nozzle (21<SP>1</SP>) and means (11) lower the parison (3) into the opened mould (6), the lower end being clamped by means (41) before closing the mould (6) and locking it by means (42-45). The parison (3) is further blown through nozzle (211) which is then closed by means (48) which also close off the parison. Neck piece (24) is inserted in the mould flush therewith and the parison is finally blown by needle (35) passing through the neck piece (24). Members (3, 4 and 21) return to their initial positions to operate on further extrudate while the article is removed from the mould by air from needle (35). Material in the neck piece is then trimmed out. The closed end part of the parison may be formed by injection moulding.

Filed: 1966-12-05
Abstract: 1,207,488. Magnetic structures. NATIONAL RESEARCH DEVELOPMENT CORP. 4 Dec., 1967 [5 Dec., 1966], No. 54273/66. Heading H1H. [Also in Divisions C7 and H3] In a magnetic store (see Division H3) a wire is coated with a ferrite. The coating is applied by immersing the wire and an electrode in a liquid such as alcohols, ketones, esters, hydrocarbons on pure water containing a suspension of ferrite particles, applying a potential difference to the wire and electrode to cause electrophoretic deposition of the particles on the wire until the deposits coalesce and sintering the deposits. In an example the ferrite solution comprises a manganese-magnesium ferrite, presintered and ground to mixed particle sizes of the order of one micron or less, absolute ethanol, Shellac solution and ferric chloride solution. Voltages from 6 to 120 volts are applied across the wire and electrode for one to two minutes. After deposition sintering is carried out by heating in air to 1360‹ C. for 20 hours, allowing to cool to 110‹ C., changing the atmosphere to nitrogen and maintaining the temperature at 1100‹ C. for 2 hours and allowing to cool to ambient temperature. In order to reduce strain in the ferrite during or after sintering an underlayer of a low melting point or easily oxidizable conductive material may be deposited on the wires before the ferrite, which layer is then melted or oxidized away. The sintering may be carried out by heating the electrical conductor in a controlled atmosphere. The wire may be a noble metal such as platinum or platinum alloy.

Abstract: 1470174 Modifying glass surfaces PILKING- TON BROS Ltd 20 Nov 1974 [23 Nov 1973] 54497/73 Heading C1M The surface 32 of glass 30 is modified by contact with molten metal body 36, the glass being subjected to anodic treatment causing cation migration from body 36 to glass 30, the glass being periodically treated during the migration to cathodic treatment by transmission of a cathodic pulse of preset duration to body 36, and the time interval between the end of the cathodic treatment and the resumption of the anodic treatment being regulated. The cathodic pulse duration may be such as to cause migration of cations from the glass into body 36 to maintain non-oxidizing conditions therein. The quantity of such cathodic electricity may be 5-50% of that in the anodic treatment. Alternatively, the cathodic pulse may be applied before the cations introduced by migration into the glass 30 can disperse from surface 32, so that some at least of the cations are reduced to give a metallic dispersion. For the latter purpose the cathodic electricity should be 30-99% of the quality of anodic electricity. The molten metal body 36 may be located on a bar 31, the glass 30 being supported on molten metal bath 10. The treatment may be at 700-800 C. in an atmosphere of 90 vol. per cent N 2  and 10 vol. per cent H 2 . Molten metal body 36 may be of indium (bar 31 being mild steel), lead (bar 31 of Ru. coated steel) or an alloy of 98 wt. per cent Pb and 2 wt. per cent Cu (bar 31 of copper).
