Abstract: 934,587. Extracting electrolytic-furnace gases. VEREINIGTE ALUMINIUMWERKE A.G. June 26, 1961 [July 27, 1960], No. 23086/61. Class 8(2.) Gases evolved at prebaked anodes 8 of an electrolytic aluminium furnace are extracted through a hood 14 the gas inlet of which is disposed below the crust 5 of solidified electrolyte and in the gas space 7 formed above the surface 4 of the liquid electrolyte 3, so that the surface 4 below the hood inlet is kept in a liquid state. The electrolyte 3 principally consists of cryolite, and the gases which comprise carbon monoxide and carbon dioxide and which have entrained therein oxide, fluoride and carbon dust, collect in the space 7. The hood 14, Figs. 4 and 5 (not shown), is formed with recesses which are filled with alumina to provide insulation for the hood. The latter has side ducts through which alumina may be fed to the furnace or through which combustion air may be admitted to the space 7 so that the exhaust gases are burnt in the space 7; alternatively, the gases pass from the hood 14 through a duct 17 to a burner (not shown). A dust separating drum 16 is provided in the duct 17. The gases may then pass to other dust separating and gas washing plant. In furnaces which have movable anodes the hood is suspended from a lever mechanism or a cable to permit a constant height to be maintained above the surface of the electrolyte. In another embodiment, Fig. 3 (not shown), two exhaust hoods are provided.

Title: Gated emitter coupled amplifier unit for a multiple input instrumentation amplifier
Inventor: UHLING THOMAS F
IPC: H03K17/62
Filed: 1996-02-05
Abstract: A first amplifier channel between an input and output includes an input transistor emitter 106 and a first output transistor emitter 108 connected together to form a first emitter pair. A current source 125 is connected to the emitter pair via a transistor which is controlled by a latch. Programming the latch permits the channel to be turned on or off. The emitter pair is connected to a positive voltage through a resistor 144 and to ground through a diode 142 to force it to a controlled off voltage, which prevents signals from passing when the channel is off. There is a output driver amplifier 118 in a feedback circuit. An outdisable circuit (fig 2) controls the voltage and current of the output driver amplifier to place the output in a state in which it appears electrically as an open circuit when the channel is off. Multiple programmable amplifiers can be combined to make a multiplexer, a selectable gain circuit, or a selectable attenuation circuit, all with high band width and high signal integrity.

Title: Booster
Inventor: HORIKOSHI SATORU
IPC: B60T13/57
Filed: 1996-03-05
Abstract: A booster comprises a first valve element 7 for seating on a first valve seat 4 on a valve body 2, and a second valve element 8 for seating on a second valve seat 6 on valve plunger 5. A first spring 11 urges the first valve element rearwardly into sealing abutment with the second valve element. A second spring 16 having a resilience greater than that of the first spring urges the second valve element towards the second valve seat. The diameters of the seat areas S1 and S2 are substantially equal. An increased responsive area to the negative pressure can thereby be secured in a region radially outward of the first seat area S1, thus allowing reduction of the compression load on the second spring and, in turn, allowing reduction of the input required to initiate operation of the booster.

Title: Motor/manually driven sliding variable resistor
Inventor: ASANO MASAHIRO
IPC: H01C10/14
Filed: 1996-02-21
Abstract: An annular groove 20a is formed in the support shaft 20 of a belt driven pulley 10. The support shaft is inserted into opposing slots/holes 17a, 16a in opposing plates 17, 16 such that the annular groove 20a grips the plate 17. A motor/manually driven sliding variable resistor uses this pulley support to simplify assembly, the pulley 10 being held on a support frame 6 by the tension of a belt 11. The resistor includes means to prevent the occurrence of noisy sounds in motor-driven operation. The motor 7 drives a driving pulley and toothed belt 11 guided around the driven pulley 10 to move the slider pieces 25, 26 of the resistor. The pieces are held on a slider receiver 22 mounted to a manually movable belt operating member 21, the belt being tightly held between the operating member and slider receiver. A protruding lug 22c formed on the slider receiver 22 is inserted into an L-shaped portion 21e formed on the operating member 21, tightly holding the belt 11 between the lug and L portion. At the same time, a latch pawl [21h, figure 9] is snap-fitted into a latch groove [22e, figure 11] for joining the operating member 21 and the slider receiver 22 together into one unit. A guide member 9 is disposed around the driving pulley 8 to leave a gap smaller than the tooth height of the belt teeth 11a between the guide member 9 and the belt 11. This stops the motor when the slider pieces have reached their end positions, thus reducing noise.

Title: Emitter resistance for improving IGBT short-circuit capability
Inventor: PELLY BRIAN R
IPC: H02H9/02
Filed: 1998-02-27
Abstract: Emitter resistors are inserted in series with high efficiency IGBTs to reduce the effective gain of the IGBTs under short-circuit. Under normal conditions, the voltage drop across the resistors is very low. The resistors may comprise existing current-sensing resistances, bond wire resistances, thick film resistors, or connector resistances. The resistors may be positive temperature coefficient elements such as polysilicon resistors or MOSFET channels (figure 5). The technique allows application of high-efficiency IGBTs in motor drive inverters. Only the lower IGBTs need emitter resistors if a fault level discriminator (figure 7) is inserted in the upper supply rail to detect shorting of the outputs to the negative rail.
