Title: Needle inspection system for circular knitting machines
IPC: D04B35/18
Filed: 1973-10-05
Abstract: 1420666 Knitting-machines APPALACHIAN ELECTRONIC INSTRUMENTS Inc 5 Oct 1973 [31 May 1973] 46610/73 Heading D1C A photoelectric needle sensing system includes a detector head mounted by three slideslideway combinations permitting adjustment in three different directions. The detector head comprises a casing 15 housing a lamp 24, and carrying a tube 18 containing an objective lens system 19a-c, for focusing light onto the heads of passing needles. The return beam is directed by a beam splitting mirror 32 to a phototransmitter. The head is mounted in the opening 51a of a holder 51 mounted by a slide-slideway 49-48 at the top of a pedestal 47. The pedestal is mounted on a base 36 by two further slide-slideway combinations 45-44; 40-39. Each slide is adjustable along its slide way by a lead screw. The angular orientation of the latter two combinations can be adjusted by set screws. Combination 49 - 48 provides optimum focus adjustment of the filament image onto the needles. Slide-slideway 45-44 permits the holder to be moved towards and away from the needles, moving the light spot up and down the needle. Rotation of this combination relative to 40 - 39 allow adjustment of the lead or log angle relafive to a cylinder radius. Combination 40- 39 permits adjustment parallel to a cylinder tangent, permitting accurate phasing with one or more detectors similarly mounted above the dial needles. If a cut line is desired in the fabric hookless signal needles 72 are provided in the otherwise empty tricks of the cylinder and dial. Each needle has a cut and polished reflecting surface 73. Series of unbroken cylinder and dial needles produce trains of pulses 180‹ out of phase. The pulses are amplified and fed to countersvia an OR gate in the case of two dial detectors. Each counter goes from "0" to "1" for an undamaged needle, but is reset to "0" by detection of an undamaged needle of the other bed. If however the following needle in the other bed is damaged (a broken or missing hook), a counter at "1" will go to "2" at the next pulse. A "2" count resets a flip-flop circuit to light a lamp and stop the machine. When the reset button is depressed there is a delay on the operation of the detector - equivalent to 314 of a cylinder revolution at 15 r.p.m. To minimize the chance of false stopping the circuit may be set to detect a defective needle twice before the machine is stopped.

Title: Signal translating apparatus
IPC: H03K5/00
Filed: 1970-10-02
Abstract: 1329582 Pulse signal translating circuits COMPAGNIE DES COMPTEURS 2 Oct 1970 [2 Oct 1969] 46950/70 Heading H3P An arrangement responsive to the relative frequency of two pulse trains E1, E2 comprises: means 10 for deriving from these trains res. pective pulse trains S 1 , S 2  which are separated in time; a gate 15 having a first state in which a first input pulse train S 1  is passed to output F; and means 11, 12 responsive to a first pulse in a second input pulse train S 2  to inhibit the gate 15, and responsive to a succeeding pulse in train S 1  to reopen the gate. If no signal is present at S 2 , bi-stable 11 produces a "1" on line J, and an S 1  pulse is fed via NOR 13 and delay 14 to trigger JK flipflop 12 to a "1" on line Q, which enables NAND gate 15. The S 1  signal is inverted at 16 and the resulting S 1  signal is passed by NAND gate 15 to appear as S 1  at the output F. When a pulse occurs at S 2 , bi-stable 11 is switched to provide a "1" on line K, and the next trigger pulse on line D will switch JK flipflop 12 to "0" on line Q, so inhibiting gate 15. The next S 1  pulse will not therefore be passed by gate 15, but will reset bi-stable 11 to J = 1 so that the next trigger pulse on line D will switch JK flipflop 12 back to Q = 1 and reopen gate 15. If we assume the frequency of S 1  to be greater than that of S 2 , the output at F represents the frequency difference. Similarly if the frequency of S 2  is greater, and elements 161, 15<SP>1</SP> are added, the difference signal appears at F<SP>1</SP>. If a further NAND gate 17 is added, detection of parasitic pulses present in two signals of nominally the same frequency may be detected.

Abstract: 1,073,777. Preventing and extinguishing fires in aircraft. JET SET Ltd. Dec. 9, 1963, No. 48545/63. Heading A5A. Fires and/or explosions in aircraft are extinguished or prevented by introducing into the air space between the engine and its nacelle two liquids which react to form a foam, thereby removing air and forming an insulating layer between the engine and the remainder of the aircraft. Suitable liquids are phenolformaldehyde polymers and urea-formaldehyde polymers and an acid e.g. sulphuric acid. In the embodiment described, the two liquids are contained in reservoir 25 and the smaller internal reservoir 25a, both reservoirs being pressured with a non-reative gas. A temperature rise in an engine nacelle 23 or 24 actuates a thermally sensitive switch 33 or 34 which operates an electrical system, shown schematically in Fig. 6 (not shown), which actuates the solenoid-operated valves 32 and 29 or 30 to allow the liquids to flow in conduits 27 and 28 to one or more distributor nozzles 26 within the engine nacelle. The electrical system also operates a warning system in the control cabin and incorporates a time-relay system whereby a manual operating system may be operated by the pilot either to over-ride the automatic system or to allow the automatic sequence to continue. In the case of multi-engined aircraft, means are provided whereby the liquids are freed in only one or in all engine nacelles as necessary, means being present to allow only the proportional amount of the total liquids to be released from the reservoir to any one engine.
