Title: Control system having multiple electrode current controlling device
IPC: H01L45/00
Filed: 1967-08-11
Abstract: The Specification describes the construction of a semi-conductor switching device 19 for connection to a load circuit (see Division H3). The switching device is symmetrical and switches from a high resistance condition to a low resistance condition when a threshold voltage is exceeded. The device may be formed so that it switches back to the high resistance state either when the current through it falls below a certain threshold value or increases above a threshold current. The semi-conductor material may be formed as bodies, wafers, layers or films by casting from a molten condition, by cutting or extruding from an ingot, by vacuum deposition or by sputtering. The materials include boron, carbon, silicon, germanium, tin, lead, nitrogen, phosphorus, arsenic, antimony, bismuth, oxygen, sulphur, selenium tellurium hydrogen, fluorine, chlorine, aluminium, gallium indium and thallium vanadium, tantalum niobium and zirconium. The load electrodes 15, 16 are connected to the body of the switching device in a non-rectifying manner by mechanical pressure, soldering, vapour deposition or sputtering. The load electrodes may be of tantalum, graphite, niobium, tungsten or molybdenum. The switching device may have two load electrodes 15, 16 and two control electrodes (17, 18, Figs. 1, 11-13, not shown) or one control electrode 17 (Figs. 5-10, not shown). The control electrode (42, Fig. 15, not shown) may be formed as a high resistance, e.g. of tantalum oxide, in which case printed circuit or microcircuit techniques are used. The resistance material may be responsive to moisture, light and temperature, such as, lithium compounds cadmium or lead sulphide, lead or zinc or cadmium selenide, zinc or silver telluride compounds of elements from Groups II and VI e.g. barium titanate respectively or pressure. The resistance can be a separate component (Fig. 14, not shown) connected to the control electrode (42). An insulating layer or a rectifier junction may be formed between the control electrode and the body 19 of the device (Figs. 13, 17, 19, not shown). The threshold values are determined by the shapes and chemical compositions of the elements.

Filed: 1970-04-28
Abstract: An electro-erosion circuit comprises a pair of series connected power sources 10, 12, a first electronic switch 18 connected in series with one of the sources 12 and the machining gap 14-16, a second electronic switch 30 connected in series with both of the sources 10, 12 and the gap and a drive voltage source 28, 28a connected to the control electrodes of both of the switches 18, 30 to turn them on and off in phase to provide superimposed pulses to the gap. Sources 10 and 12 are high and low voltage sources respectively whilst sources 28, 28a may be the same source or separate sources operated in unison. When a transistor 40 is switched off, a transistor 42 is turned on by a source 46 to cause transistors 30, 301 to be turned on via rectifier 82 and resistors 80, 72 so as to provide a high voltage pulse across the gap superimposed with the low voltage pulse provided by transistor 18. When transistor 40 is turned on, a diode 56 ensures turn off of transistor 42 by the bias voltage across resistor 60. When transistor 42 is switched off, a transistor 44 is turned on to apply a source 68 across the base-emitter junctions of transistors 30, 301 to turn them off. The circuit includes gap current limiting resistors 20, 36. The emitter of transistor 18 is clamped to zero by a rectifier 24 and capacitor 26. For rough machining, the transistors 30, 301 are decoupled from the machining gap by opening switches 32, 50 and switch 18 only is operated to provide low voltage pulses. For a high voltage finishing operation, the drive source 28 is disconnected from the transistor 18.

Title: Vials feed device along an inclined plane for vials handling machines
IPC: B65G47/14
Filed: 1974-01-28
Abstract: The inclined plane is formed by a first fixed grid and a second movable grid. Each grid comprises elongated bars extending in the vial feeding direction and spaced laterally from each other, with the bars of the second grid alternating with the bars of the first grid. At the lower end of the inclined plane, there are provided delivery members which separate the advancing mass of vials into regular rows for transfer into a conveying means supplying the vials to a vial handling machine. The second grid has imparted thereto a cyclical motion with two trajectories. In the zone nearest to the vial separating members, the second grid follows a trajectory which is substantially linear in the vial feeding direction while, in the zone farthest from the separating members, the trajectory has an annular and substantially elliptical form. Thereby, the second grid performs a cyclical lifting of the vials from the first fixed grid with an advance of the lifted vials in the feeding direction relative to the first fixed grid. The device is particularly useful for vial handling machines in pharmaceutical industries.
