Title: Amplifier with means for eliminating crossover distortion and integrator therefor
Inventor: CHARLESWORTH JOHN RENNIE
IPC: G06G7/184
Filed: 1997-10-15
Abstract: An audio amplifier has two transistors TR1 and TR2 in series between positive and negative supply rails. A current compensation circuit 10 is connected between the positive supply rail and the emitter of transistor TR2, and is arranged to supply current to the emitter of transistor T2. The current compensation circuit 10 includes an amplifier 12 which is arranged to sense the voltage drop across a first emitter resistor RE1, and control a current generator 14 in dependence upon the measured voltage drop, which is proportional to the current flowing through transistor TR1. Thus, in use, the current compensation circuit 10 acts to increase the current in TR2 by the same proportion as in TR1, in order that TR2 does not become reverse biased. Therefore, the output resistance continues to approximate to RE1 in parallel with RE2, even when the current into the load RL is greater than the quiescent current. In this way, the effects of crossover distortion which are prevalent in Class B amplifiers are greatly reduced.

Title: Device for measuring the mass flow rate of a flowing medium
Inventor: HECHT HANS
IPC: G01F1/68
Filed: 1997-11-14
Abstract: A measuring device comprises a measuring element (2) disposed in the duct (5) and a non-uniform grid (21) upstream of the measuring element (2) with respect to an intended direction of flow through the duct (5). In order to achieve a symmetrical speed distribution across the duct (5) even in the case of a disturbed onward flow, the grid (21) has flow openings (40) which at least in regions (42, 43) have a different throughflow cross-section. The throughflow cross-sections of the flow openings (40) are adapted to the entering flow in order to cause a flow with substantially uniform speed distribution downstream of the grid (21). The device is particularly suitable for the measurement of the mass flow rate of the induction air of an internal combustion engine. Various forms of the grid (21) are shown. The openings in the grid (21) are formed by punching out of a thin metal strip, or by means of a laser; alternatively, openings may be etched in a ceramic element.

Title: Continuous band manufacture
Inventor: COOKSON ANTHONY
IPC: B23K37/04
Filed: 1997-12-13
Abstract: A band saw strip manipulator 10 is arranged to receive a toothed metal strip 12 for welding from a cut to length machine by powered rollers. The strip 12 extends between a first edge detector 14 at one side of the manipulator 10 and a second edge detector 16 at the opposite side of the manipulator 10 either side of a carriage 22 mounted for vertical movement. When the strip 12 has been approximately centrally located the carriage 22 moves upwardly from the position shown in figure I thereby pulling the strip upwardly until the edge detectors 14 and 16 detect the ends of the strip 12. first and second end clamps 18 and 20 are then closed and pivoted about first and second guide rollers 24 and 26 so that the two ends of the strip 12 are located in close proximity for welding together.

Title: An apparatus for connecting a modem to a plurality of telephone lines
Inventor: DOH DUK-HYUN
IPC: H04M11/06
Filed: 1997-12-19
Abstract: An apparatus is disclosed comprising a first codec 16 which converts an analog signal output from the modem 10 into a PCM signal to be supplied to a time switch 18 and vice versa. Each of a plurality of further codecs 10-24 converts an analog signal output from a corresponding telephone TEL1-TEL2 line into a PCM signal to be supplied to the time switch 18 and vice versa. The time switch 18 transfers the digital signal output from the first codec 16 to a selected one of the further codecs 20-24 and vice versa, thereby loading the data on a respective channel. Connecting a modem to a plurality of telephone lines in this way allows the modem to continue communications even in the event of a line failure.

Title: Device for tensioning the cut-in spring in actuator units for circuit breakers, in particular vacuum circuit breakers
Inventor: MUECKSCH DIETMAR
IPC: H01H3/30
Filed: 1995-04-04
Abstract: The invention concerns a device for tensioning the cut-in spring in actuator units for circuit breakers, in particular vacuum circuit breaker, the cut-in spring (7) being designed as a tensioning spring which is in contact with a cam (2) mounted on the cut-in shaft (5) and which can be tensioned both by an electric motor (20) and by a hand-turned shaft (21) through a spur-gear train, the last spur gearwheel (1) also being mounted on the cut-in shaft (5). The aim of the invention is to design a tensioning device in which the spur-gear train operates without overrunning, and reversing of the cam (2) is prevented or limited by the cut-in spring (7). This is achieved by virtue of the fact that the last spur gearwheel (1) in the spur-gear train is disposed over an overrunning bearing (6) on the cut-in shaft (5) in such a way that, when cut-in spring tensioning begins, the cam (2) and hence also the cut-in shaft (5), are carried directly by the last spur gearwheel (1) out of a position in which they are located past the bottom dead centre position (9) of the shaft (5) as the cam (2) rotates upwards, while, during the cut-in phase, the last spur gearwheel (1) is locked in position, when the cut-in shaft (5) turns through bottom dead centre (9), by the overrunning bearing (6) and by the operative connection with the other spur gearwheels in the spur-gear train.
