Title: Coil cutting machine
Inventor: ERICSSON GEORG ALBERT
IPC: B21F35/00
Filed: 1962-04-30
Abstract: 970,137. Metal wire feeds. LUMALAMPAN A.B. April 30, 1962 [April 28, 1961], No. 16387/62. Heading B3W. In an apparatus for cutting wire consisting of alternate straight and coiled sections the wire is fed intermittently from a storage reel to a cutting device, a support for the reel being arranged to move the reel towards and away from the feeding direction of the wire, the forward motion being made during the feeding movement of the wire. The apparatus comprises a cam-shaft 7 which controls the various functions of the machine. A cam 9 reciprocates a plate 10 transversely to the shaft 7 and pivoted to the plate at 16 is an oblique bar 11 which bears on a roller 12 attached to a longitudinally slidable shaft 14. The stroke of the shaft is determined by the angular setting of the bar 11, a scale 17 indicates the stroke. The wire T is fed forward by jaws 2 mounted on the shaft 14, and these jaws are controlled by a cam 19 and a follower arm 21 fixed to a rotatable shaft 22. Keyed to the shaft 22 is a flanged sleeve which opens the jaws 2 against spring pressure. When the jaws are in the closed position a gap is maintained between them by set screws 30, 31. Nozzles 33, 34 on either side of the jaws guide the wire. The feed spool 1 is mounted at one end of a bell-crank 51 which pivoted at 52 and operated by a cam 53 through an adjustable link mechanism 54. A spring 55 maintains the follower 56 against the cam 53. Two shears 4, 5 are actuated by a common cam 42, the shears 5 are bolted to a bracket 46 and the spacing between the shears can be adjusted by means of a threaded spindle 47. A pair of tongs 3 grip the free end of the wire at the end of the feeding movement and are opened and closed by a cam 35. Operation.-At the beginning of a cycle the jaws 2 are at their rearmost position and close over a straight length of wire U without gripping it, due to the setting of the screws 30, 31. The jaws move forward until they abut the end of a coil and then feed the wire forward. At the completion of the movement the tongs 3 close on the wire and the jaws 2 open, move rearwards to their starting position and close on to the wire again. The shears 4 and 5 cut the wire and the cut length falls into a hopper. The tongs 3 then open and brushes sweep across them to remove the waste end of wire. As the wire is fed forwards the spool 1 also moves forward but at a slightly lower rate to prevent sagging of the wire. When the tongs 3 have gripped the wire the spool returns and rotates to unwind a length of wire.

Filed: 1940-11-14
Abstract: 542,857. Protective cut-out arrangements. DAVIDSON, G. W., EMSLEY, A. E., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 14, 1940, No. 16472. [Class 38 (v)] Re-closure of a circuitbreaker 1 connecting a load circuit 3, 4 to the supply 5, 6 is adapted to be prevented by a no-volt device having a main coil 7 connected across the supply, or to an associated circuit, so as to be operative to prevent closure if the current is low due to low supply voltage, and an auxiliary coil 8 inductively related to coil 7. The flux due to 8 oppose that of 7 and is due to the current induced by the latter, its magnitude being dependent on the load-circuit impedance. The arrangement is such that reclosure of 1 is prevented while overloaded or short-circuit conditions prevail in circuit 3, 4. An indicator or ammeter 30 is provided, also a switch 11 for cutting-out the coil 8 when breaker 1 is closed. The invention is applicable also to polyphase systems with delta or star-connected loads, the three sets of coils being connected across corresponding pairs of lines or between corresponding lines and the neutral, Figs. 2, 3 (not shown). The Provisional Specifications outline other forms of reclosure-preventing means, some of which are applicable to D.C. circuits and use resistance-potentiometers.

Title: Apparatus for producing sounds of a musical character
IPC: G10H3/08
Filed: 1931-06-05
Abstract: 380,781. Inductor alternators. MIDGLEY, A. H., Fairfield, Harefield Road, Uxbridge, Middlesex. June 5, 1931, No. 16495. [Class 35.] In an all-electric organ comprising devices producing electrical vibrations of different frequencies, and means for selecting any of such frequencies and for converting them into corresponding sound waves, the amplitude of each fundamental and harmonic electrical vibration is determined by the previous selection or adjustment of the reluctance of its respective magnetic field. A number of magnetic fields cross an air-gap and have a common return path or yoke and a common source of energization, the strengths of the fields each being periodically varied by,variations in the width of the.air gap, obtained by the rotation of perforated or shaped discs or the like. A number of discs are geared together so that the frequencies of the notes produced have a predetermined relationship. In Fig. 2, a rotary iron disc a mounted on two bolted iron drums b, c is perforated with concentric rows of holes, the number of holes in the various rows corresponding to the frequencies of the fundamental and the harmonics of a note. Radial iron bars e, i are arranged opposite the two faces of the disc on stationary aluminium mountings d, h. The iron core of an electromagnet g holds an adjustable bar f close to the bar e and also holds the other end of the bar i. By individually adjusting iron screws k provided in the bar i, the tone-value or stoptimbre of the note produced in a coil l on energization of magnet g, can be determined. The adjustment of the screws may be readily effected with the aid of a templet. The harmonics may be produced in phase or out of phase with the fundamental. To produce a " celeste effect, an adjustable short iron bar n is fixed on the bar i and the iron drum c is made elliptical. To produce a " tremolo " effect, an alternating current is superimposed on the current supply of the coils g. In a modification, Fig. 8, not shown, the rotating discs have concentric ridges with undulating faces and the bars i and screws k are replaced by strips with integral teeth produced with the aid of a templet. The undulations in the ridges may be shaped to produce special wave forms. A ridged cylinder, or series of circumferentially undulated discs, may be used.
