IPC: D01H1/00
Filed: 1958-10-17
Abstract: 875,690. Flyers for speed frames. T. M. M. (RESEARCH) Ltd. Oct. 2, 1959 [Oct. 17, 1958], No. 33229/58. Class 120(2) In a flyer for a speed frame a leg 16 carrying the presser foot is pivoted at a point 18 along its length, the mass of the leg being so distributed about the pivot that the centrifugal force acting on that part of the leg above the pivot exceeds that acting on that part of the leg below the pivot so that during operation, the presser foot is subjected to an inward force. The leg is balanced by a second leg 17 which is of conventional construction or is arranged similarly to the first leg; each leg is pivoted to an arm 14, 15 connected to a sleeve 1 having a pin 13 engaging a slot in the top of the spindle. The presser foot 24 and the corresponding foot 25 are pivoted to or integral with the corresponding legs and are so curved as to maintain contact with the package throughout the build; the foot 24 is slotted to provide a guide-eye.

Title: Improvements in or relating to supply and ignition circuits for electric discharge lamps
IPC: H05B41/04
Filed: 1969-07-02
Abstract: 1,249,255. Supply circuits for discharge lamps. COMPAGNIE DES LAMPES S.A. 2 July, 1969 [31 July, 1968; 28 Nov., 1968], No. 33375/69. Heading H2H. A discharge lamp starting circuit includes a bi-directional semi-conductor element which is triggered so as to discharge a capacitor. The pulse produced is amplified by a ballast inductance connected to the lamp. In the circuit shown in Fig. 1, the starter circuit 8 is connected across A.C. supply terminals 6, 7 and is also connected to three tapping points on the ballast inductance 4. A capacitive voltage divider 9, 11 is also connected across the supply. When the main switch 5 is closed, a further capacitor 16 charges until its potential is sufficient to break down a diac 14b which triggers a triac 14a into conduction. The capacitor 9 now discharges through the section 4a-4b of the inductance 4 which then applies an amplified voltage to the lamp 1 resulting in ignition. The components are chosen so that the triac is gated at a peak of the supply voltage and maximum voltage is available. After ignition, resistors 12, 13 are arranged to maintain the voltage on the capacitor 16 below the value necessary to break down the diac 14b. In a modification, Fig. 2 (not shown), two triacs connected through an isolating transformer are used. Breakdown of the first triac generates a control signal for the second, through which the capacitor 9 then discharges as before.

[Class 44] A fastening for aeroplane cowlings, doors, covers, &c. comprises a casing 1 in which is slidably mounted a plunger having a head 4, normally flush with a flange 2 by which member 1 is secured to the cowling &c. 14, and a pair of webs 5. A transverse locking arm 7 projecting through and guided by an aperture in one wall of the casing 1 is mounted on a pivot pin 6, the ends of which extend through inclined slots 9 in the webs 5 of the plunger and into oppositely inclined slots or grooves 10 in the casing. On inward movement of the plunger the slots exert a cam action on pin 6 to retract the arm 7. A spring 11 anchored at one end round pin 6 and bearing at the other end against the plunger head 4 biasses the parts to the engaged position shown. When the plunger is depressed to release the fastening it may be moved laterally to engage the edge of head 4 in a notch 12 to hold the latch retracted. The casing 1 is passed through an aperture in the structure 16 to which the cowling &c. 14 is to be attached, and the arm 7 may engage any suitable keeper or abutment. As shown, it engages behind the inner end of a tubulure 15. The inner edge of the arm 7 is inclined to draw the parts 14, 16 together with a wedge action. Specification 361,963 is referred to.

Abstract: 842,756. Electromechanical filters. TELEFUNKEN G.m.b.H. Nov. 1, 1957 [Nov. 2, 1956], No. 34157/57. Class 40(8). An electromechanical filter comprises a number of mechanical torsional resonators coupled by members which vibrate in a longitudinal mode The filter of Fig. 1 consists of three cylindrica torsional half-wave resonators 1, 2, 3 coupled by wires 4, 5, 6 welded to their peripheries. Three of the wires are firmly connected at either end to blocks 8, 9 which are dimensioned to form mechanical short-circuits. The fourth wire is joined at its ends to ferrite input and output elements 10, 11 surrounded by driving and pickup coils 12, 13. Magnets 14, 15 provide biassing fields. A single wire is sufficient to provide coupling if some other supporting means is used for the resonators. In a modification (Fig. 3), all four wires are connected to the terminal blocks and the first resonator 1 forms the input transducer. For this purpose the resonator takes the form of a circumferentially polarized ferrite cylinder surrounded by a coil 20. The output transducer may be similarly constructed. Alternatively, transducers of the form shown in Fig. I may be coupled by extra coupling wires to the first and last resonators. The coupling between successive pairs of resonators may be varied by varying the points of attachment of the coupling wires. Thus the wires may be attached (not necessarily symmetrically) to various points either on the curved or flat end-surfaces of the cylindrical resonators (Figs. 4, 5, 6, not shown).
