Title: Residue generating circuit
IPC: G06F7/499
Filed: 1973-10-10
Abstract: 1430814 Residue generating circuits INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1973 [14 Dec 1972] 47195/73 Heading G4A A residue generating circuit for calculating the residue modulo m of the sum of an augend 1 (Fig. 2) and a plurality of addends 2 1  ... 2 n  comprises a calculator 5 including (1) a multinumber adder 11 (Fig. 3) generating simultaneously from the augend and addends a plurality of sets of words 0 1  ... 0 j  each of a predetermined number of bits and (2) a residue modulo m generator 12 receiving simultaneously the outputs of the adder 11 to calculate the residue of the sum of the words 0 1  ... 0 j . As described the circuit checks the operation of an adder 3 also receiving the input words, its output being connected to a residue modulo m generator 8 (in the embodiment m = 9), the output of which is compared with the output of the calculator 5 to derive in the case of non-equality an error signal. The multinumber adder 11 preferably comprises four column adders each receiving one of the four bits of seven input digits. Each column adder comprises a matrix (36b, Fig. 5, not shown) in three sections (37b, 38b, 39b) each receiving via phase splitters and decoder/ drivers (14b, 15b) inputs derived from four of the digits fed in on column leads and inputs derived from the other three of the digits fed in on row leads, there being transistor switches selectively connected at the cross-points so that for the least significant bits of the input words (1) a sum output bit (a) is "1" if an odd number of the seven input bits are "1", (2) a first carry output bit (e) is "1" if 2, 3, 6 or 7 of the input bits are "1" and (3) second carry output bit (i) is "1" if 4, 5, 6 or 7 of the input bits are "1". Similar output bits (b,f,j; c, g, k and d, h, l) are derived for the three more significant bits, these being grouped into two sets 13, 14 (Fig. 6), of three words and fed to two modulo 9 residue generators 15, 16 respectively. Generator 15 comprises X and Y decoders (18, 19, Fig. 7, not shown) receiving bits d, g, i and h, k, l respectively to each derive a signal on one of eight leads (60-67, 20-27) which are selectively fed to the five columns and four rows of each part (m 1 , m 2 , m 3 , m 4 ) of a matrix having transistors at selected cross-points to derive an output bit (w, v, u, t) for each part, where the word (t, u, v, w) is the residue modulo 9 of the sum 00d + 0hg + lkj. Generator 16 is similar and derives a word (p, q, r, s) which is the residue modulo 9 of the sum cba+fe0+i00. The outputs of the generators are fed to a further residue modulo 9 generator 17 which comprises X and Y decoders (18<SP>11</SP>, 19<SP>11</SP>, Fig. 9, not shown) each receiving one of the outputs and feeding the rows and columns respectively of a four part matrix to derive four output bits (R 1 , R 2 , R 4 , R 8 ).

The sampled voltage is held on a capacitor 51a, associated with an operational amplifier 51, and is applied to an operational amplifier 52 whereby it is summed or balanced out, with respect to a " zero " voltage valve adjusted by a potentiometer 56 connected to a bias supply. The output from amplifier 52 is inverted by an operational amplifier 53 and the outputs are applied to the ends of a centre-tapped potentiometer 55 serving as a span adjustment control for the data curve being followed (see Division G2-G3). The signal from the slider of the potentiometer is fed to an operational amplifier 54 providing an analogue output.

The tension of an implosion-protection strap mounted around the face-plate of a cathode-ray tube is prevented from exceeding a given value by providing in the strap a region of reduced cross-section, by forming an aperture therein, whereby excessive tension exceeds the yield point of the strap material in the neighbourhood of the aperture, and causes the strap to lengthen accordingly. Alternatively, if the tension does not exceed the yield point, measurement of the elongation of the aperture permits the tension to be deduced. The strap, if continuous, may be sweated on to the tube envelope, or its ends may be spot-welded under tension.

Abstract: 1337202 Making composite wire; bending KABEL UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 25 Oct 1971 [26 Oct 1970 (2)] 49393/71 Headings B3A and B3E A method for the continuous production of copper clad aluminium wire includes bending a single strip of copper to form a sheath around the aluminium core and welding the strip edges together, all in a protective atmosphere and then reducing the diameter of the sheathed wire. The reduction in diameter is followed by heat treatment to produce a diffusion layer at the inter-face between the core and the copper sheath. An extruder 1 supplies aluminium wire 2 to storage means 3, which is fitted with guide rollers 4, 5 and located in a protective gas enclosure 7. Alternatively continuous casting apparatus may be provided. The copper strip 9 is fed from storage means 10 to a cleaning unit 13, the storage means having provision for welding strips end to end. The strip passes through a drier 14 and a brushing device 15, which has brushing rollers 16 and backing rollers 17. The copper strip is bent into a tube by a roller device 19 welded at a welding station 6 and the sheathed wire is reduced in diameter in means 20 which comprise a drawing ring or reducing rolls. The wire drawn off means may be a disc 21, or endless band or clamp and the wire is fed to a collecting drum 22. The wire is further reduced in diameter in stages and heattreated; the heat treatment may take place between successive stages of reduction. The thickness of the diffusion layer between the copper and aluminium depends on the amount of reduction which may be 80% or more, and the heat treatment temperature. Heat treatment is preferably carried out continuously as the wire emerges from the stages of the reduction means.

Title: Dyed and printed glass fibers and a process for dyeing and printing glass fibers
Inventor: VESCIA MICHELE
IPC: C03C25/475
Filed: 1964-12-11
Abstract: Glass fibres are dyed or printed with pigments using as a binder a film-forming polymer which becomes cross-linked under the influence of a proton-acceptor and using an amino-silane or a hydrocarbon wax as an agent having hydrophobic action to promote adhesion between the binder and the glass surface, the process being carried out in the presence of a proton-acceptor, and the treated fibres being finally dried and heated.  The polymers are those having groups, for example amino or hydroxy groups, which by means of proton acceptors can enter into covalent bonds with themselves or other groups.  The preferred polymers are copolymers bearing hydrocarbon radicals as side chains in which a halogen atom and a hydroxyl group are attached to two adjacent carbon atoms, particularly a polymer obtained by co-polymerising 2-hydroxy-3-chloropropyl acrylate with other monomers.  The proton-acceptor may be an alkali metal hydroxide, carbonate or bicarbonate, amonia or an organic amine; it may be provided as the alkali present in the glass.  The glass fibres may be treated as such, mixed with other fibres or in the form of fabric. In the treatment, the various components can be applied separately or in combination.  Examples illustrate the use of copper phthalocyanine, azo dyes and carbon black as the pigments.
