Title: Power supply system having two different types of batteries and current-limiting circuit for lower ouput battery
IPC: B60L15/04
Filed: 1975-06-03
Abstract: 1473798 Supplying loads from batteries NISSAN MOTOR CO Ltd 3 June 1975 [3 June 1974 (2)] 23899/75 Heading H2H A power supply comprises a first battery 14 connected in parallel with a second battery 16 which has a lower open circuit voltage and a higher maximum output current but a smaller capacity than the first battery and a current limiting circuit connected in series with the first battery, the current limiting circuit preventing the discharge current of the first battery from exceeding a predetermined maximum value Ic. The current limiting circuit comprises a transistor 32 which is connected in series with a current measuring resistor 34 and allows the current supplied to the load 12 by the battery 14 to increase to the value Ic at which the voltage across the resistor 34 switches on a transistor 38. The conduction of the transistor 32 is therefore reduced to prevent the current exceeding the value Ic. This value is slightly below a critical current at which the terminal voltage of the battery 14 equals the open circuit voltage of the battery 16. Discharge of the battery 14 at an excessive current is therefore prevented and if the current demanded by the load exceeds the value Ic, the battery 16 discharges into the load to supply the additional current. In a modification, Fig. 6 (not shown) the current limiting circuit comprises a transistor chopper circuit. A chopper circuit is positioned between the current limiting circuit and the load in Figs. 8, 10 (not shown).

As shown, the welding tool, connected at terminals 14, 15, is fed from a secondary winding of transformer T 1 through full wave rectifier GR 1 and choke L1. The transformer has input tappings a to e for different electrode sizes, and a further secondary winding 16 feeding, through a variable transformer 19 and rectifier GR2, a separately excited motor M that drives the consumable electrode 26 using rollers 24, 25. If the feedrate is too high, the welding current rises and the transformer secondary voltage falls. Thus the excitation of motor M1 reduces to decrease the feedrate and maintain the welding current at a value dependent upon the setting of transformer 19, which may be replaced Fig. 3 (not shown), by tappings on transformer secondary 16. In another embodiment, the choke L1is replaced by a choke in the transformer primary circuit, see Fig. 2, (not shown).

A box partitioning unit consisting of two mutually perpendicular sets of slotted cardboard strips slidden together, Fig. 1 (not shown), is assembled in a machine having at least one holder 23 having sets of spring clips 7 to receive the ends of one set of the strips, a rotating arm 31 engaging through a pin-and-slot connection with the holder to drive it round a rectangular guide. The motion of the holder 23 is intermittently arrested as it travels down one side of its guide, so that a pneumatic servo 17, Fig. 2 (not shown), and a feeder 15 can push individual cardboard strips from a stack 21 into the clips 7. The strips are so arranged that their slots are directed away from the holder 23. The motion of the holder 23 is again arrested intermittently as it travels down the next section of its guide, so that another similar servo 17, &c. (not shown) can feed further slotted strips at right angles to the others on to the holder. The second set of slotted strips have their slots directed towards the holder 23. The slots in the sets of strips engage, to make a cell-like unit. Finally, the completed unit is automatically removed from the holder 23, which commences a new cycle. Notched control rails 57, 59 along two edges of the holder 23 coact with switches 63, 69 to effect intermittent rotation of the arm 31 driving the holder 23, and the corresponding energization of the servos 17. As shown, two opposite holders 23, 25 are provided. To adjust the spacing between adjacent pairs of clips 7, &c., and thus assemble partitioning units having different-sized cells, plates 41 on which the spring clips 7 are mounted can be removed from the holders 23, 25 and replaced by others, with corresponding replacement of the control rails 57, 59.

Abstract: 1461795 Cathode-ray tubes; transit-time tubes SIEMENS AG 3 June 1974 [4 June 1973] 24444/74 Heading H1D An electron beam tube for use in time division multiplex communication systems-in which n individual channel signals, in binary form and of a predetermined recurrence frequency, are impressed upon a carrier wave by two-phase modulation-includes, disposed in succession between a beam source and a collector, a first deflector device to deflect the beam out of its axis into a rotational path having a cyclic frequency equal to the pulse recurrence frequency e.g. by the production of a cyclotron or synchronous wave; a coupling arrangement consisting of n electrodes uniformly distributed around the beam axis and fed with respective individual channel signals to modulate the rotating electron beam; and a second deflector device for returning the beam to the axis and directing it therealong. In the tube of Fig. 1, which has a magnetic focusing arrangement 43, the deflectors 4 and 7 are Cuccia couplers, and the coupling arrangement 5 is formed by a plurality of radially disposed capacitor deflector plate pairs (in detail in Fig. 4, not shown) scanned in sequence by the beam, and a diaphragm 6 which transmits the beam to the collector 3 for one of the binary signals, but intercepts the beam for the other binary signal, the pulsed output from the collector 3 being thereafter employed to two-phase modulate a separately generated carrier wave, e.g. the potential across a resistor in the collector circuit may control a varactor diode in an arm of a circulator fed with the carrier wave. Reference is made to the production of an amplified output by using an electron-bombardment-induced conductivity target as the collector. In a further embodiment (Fig. 2, not shown), in which the tube also performs the pulse modulation of, and amplifies, the carrier wave, a delay line-as described, a helix-fed with the carrier wave is disposed around the electron beam path between the second deflector 7 and the collector; the binary channel signals are supplied in push-pull to the coupling arrangements of two such identical tubes, the outputs of which are combined, after one has been phaseshifted through 180 degrees, to provide the binary phase modulated carrier. In a further embodiment, Fig. 3, in which all the functions are performed by a single tube, the beam is modulated at carrier wave frequency by the helix 19 before deflection; the coupling arrangement is formed by a plurality of cylinders 20 (in detail, Fig. 5, not shown) which change the beam speed in accordance with the binary potential signal applied to the cylinders; and the resulting phase and carrier frequency modulated beam produces an amplified output signal at the output 38 of the helix 14, which is disposed in a magnetic focusing field of increased intensity.

Abstract: 954,293. Valve pulse circuits. BELL PUNCH CO. Ltd. July 1, 1960 [July 16, 1959], No. 24481/59. Addition to 925,166. Heading H3P. The circuit described in the parent Specification for providing a different number of output pulses per cycle on each of a number of output terminals is improved by limiting the voltage swing at the output terminals. The circuit comprises a multi-cathode stepping tube D, the output terminals each being coupled to a different number of cathodes. As shown, valve V provides a train of phase-displaced pulses to drive electrodes DD1 and DD2 which cause the glow to be stepped successively along the cathodes of the stepping tube D. Output terminals 1-9 are connected via one or more diodes such as W1 respectively to one to nine cathodes of the stepping tube D. In each cycle of rotation of the glow therefore, one pulse appears on terminal 1, two pulses on terminal 2 &c. Diodes W21, W22 &c. are provided to reduce rise time by limiting the voltage to which the stray capacitance charges. Since terminals 1, 2 and 3 are connected only to one group of cathodes, diodes W1, W6, W11 may be omitted. Specification 925,161 also is referred to.

Abstract: 918,027. Automatic control of pressure and position. GRINNELL CORPORATION. July 17, 1959. [April 13, 1959], No. 24593/59. Class 38 (4). In an automatic control system for positioning pipes in power plants subject to temperaturecaused movement, the operability of the system is determined by simulating the temperaturecaused movement and indicating the correction of such movement. As shown, a pipe 56, subject to small changes in position, is supported by a frame 12 and tensioned by a worm 34, driven by a motor 42, acting against a load-cell 20 having a spring 22. An arm 58 secured to a piston 24 of the load cell is positioned in dependence on the compression in the spring 22 which balances the tension in a supporting member 50. Switches 60, 62 are actuated by the arm 58 and through relays 130, 112 energize starter coils 90, 92 of a reversing starter 84 to determine the direction of rotation of the motor 42 which drives the worm 34 so as to restore the tension in the frame to the desired value. Switches 64, 66 are actuated by the arm 58 on failure of switches 60, 62 and through relays 232, 236 operate starter coils 90, 92 to prevent damage to the system. Thermal delay switches 240 are connected in series with relays 112, 130, 232, 236 to increase the response time and prevent operation of the system by vibration. The operation of switches 60, 62 is indicated by lights 122, 132 and the operation of switches 232, 236 by lights 140, 138 and alarm bells 139, 137. The system is tested by manual pushers 142, 144 over-riding the action of switches 60, 62, 64, 66. In a modification, the manual pushers energize relays, having hold-on coils, in the supply to the starter coils 90, 92 and the system is automatically cycled. In further modifications, the pipe is maintained in the vertical position by the jack or in. a position which is determined by the temperature in the pipe.
