Title: Improvements in or relating to means for automatically changing gramophone and like needles
IPC: G11B3/46
Filed: 1931-02-18
Abstract: 363,552. Gramophones. MATSUSAKI, J., Kashiwayama, Ichiba-mura, Katogun, Hyogo, Japan. Feb. 18, 1931, No. 5184. [Class 40 (ii).] Comprises a device for automatically changing gramophone needles. The tone-arm 1 consists of two parts 2, 3 which are relatively rotated to bring the sound-box 4 into its non-playing position, the part 2 being provided with a bevel gear 5 which meshes with a gear 6 on a shaft 7 carried by the part 3 and causes rotation of a shaft 20. A plunger 15, Fig. 4, extending diametrically across the sound-box, is moved by means of a rack 17 which meshes with a pinion 19 on the shaft 20. The shaft 20 is connected to the shaft 7 by a shaft 23 provided with a screw-threaded bore 25, Fig. 11, with which co-operates a screw member 26 having a head 27 and a cylindrical extension which is fixed to a connector 29 by a screw 30. The needle reservoir 41 comprises a body portion 42 provided with a spiral slot 43, Fig. 9, to house the needles and closed by a bottom plate 44 and a top cover 45. The needle reservoir assembly is held together by a spindle 49 connected at its lower end to a spiral spring 50 which is attached to a cover-plate 51. The plates 44, 45 are formed with corresponding radial grooves, as at 54, with which engage the ends of a pin 55 biased towards the outer end of the slots by the action of the spring 50 to urge the needles towards a feeding groove 57. A combined needle guiding and gripping device 60, consists of two hinged co-operating members 61, 62, Fig. 6, which are urged towards each other by a spring 66. These members 61, 62 form a gripping hole 69 and a guiding channel 70 in alignment with the feeding groove 57. In operation, when the sound-box is turned towards the' non-playing position, rotation of the gear 6 causes revolution of the screw 26 which screws into the threaded hole 25 until the head 27 engages the end of the shaft 23. After this position, rotation of the shaft 27 is transmitted to the shaft 20 and the plunger pushes a new needle into the guiding channel 70 thereby also releasing the used needle. At this stage, the needle gripper 60 is directed upwards as that the used needle is released to drop into a passage 80 and thence through a discharging hole 81 into a discharge box 85. The new needle is further pushed by the plunger 15 into the channel 70 and then shifted to the gripping hole 69, through the pressure of the spring 66, which pressure then effects a firm grip of the new needle. When the sound-box is returned to the playing position, the shaft 7 turns in the opposite direction and the screw 26 retires from the bore 25 so that no motion is transmitted to the shaft 20, but the plunger is returned to normal position by a spring 115 which acts on a gear wheel 116 in mesh with the pinion 19.

Title: An inverter
IPC: H02M7/515
Filed: 1969-02-04
Abstract: 1,262,345. Static invertors. DANFOSS A.S. 4 Feb., 1969 [15 Feb., 1968], No. 5824/69. Heading H2F. A 3 phase invertor comprising controllable rectifiers E1 to E6 (Fig. 1) fed from a constant voltage D.C. source 1, 2 via a voltage regulator 5 and producing output at UVW, is provided with a common quenching circuit including a diode D7, and a controllable rectifier E7 shunted by a commutating capacitor C1 in series with a recharging choke L4. A control circuit 7 supplies firing pulses to commutating rectifier E7 through output 8 and to rectifiers E1-E6 through outputs 9. The invertor operating frequency is controlled in dependence upon the invertor input voltage fed to control unit 7 through lines 10 so that for example constant magnetization is always imparted to a polyphase induction motor supplied thereby. The firing pulses to E7 occur six times during each cycle and cause all conducting rectifiers in the invertor to be turned OFF simultaneously whereupon a new combination of rectifiers is fired by individual pulses, or a series of pulses at the required sequence. A transformer T1 secondary and a diode D8 serve to recover magnetic energy stored during commutation by feeding back into the filter system of voltage regulator 5 which fixes the value of U 3  applied to the invertor. Commutation.-Assuming E1, E4, E6 conducting, C1 is charged via R1 to 600 Volts. When E7 is turned ON the invertor input voltage U 3  is shorted and collapses to zero and the invertor current Jw decreases while current J T1  rises as shown, Fig. 2. At the same time C1 begins to discharge current J C1  (Fig. 2) firstly through L4 and E7 in the form of a damped oscillation which as C1 becomes charged oppositely, opposes current through E7 turning it OFF. The negative current J C1  is now divided between the three branches including the still conducting rectifiers E1, E4, E6, the flow of reverse current J C1  through these rectifiers appearing as a reduction in the load current already flowing. Thus when the current J C1  reaches a negative value equal and opposite to the total current Jw still flowing in line 3 the holding currents through E1, E4, E6 drop to zero so that they turn OFF. Current J C1  is then forced to take paths through the respective anti-parallel diodes and chokes, e.g. as circuit 11<SP>1</SP> of phase U, through D2, L1, D1; line 3, D7, L4 back to C1. The voltage drops associated with these currents appear as reverse voltages across all the controllable rectifiers E1 to E7, establishing quenching conditions. A new combination of rectifiers can then be struck and the reverse current J C1  drops to zero while U 3  rises and J C1  becomes recharged via D7 and R1 respectively. The load may be a motor and the anti-parallel diodes also act to return reactive current from the load. D8 functions to restore stored magnetic in T1 to the source, T1 being a current limiting impedance in the form of a transformer.
