Patent EP-0011931-A2 (EP)
Inventor: HARTLAUB JEROME T
IPC: A61N1/37
Filed: 1979-11-05
Abstract: A cardiac pacemaker of the type responsive to heart activity to affect the operation of the pacemaker (e.g. a demand pacemaker) includes a circuit for sensing heart activity which is substantially equally responsive to electrical heart activity signals of either polarity. A differential-input differential- output preamplifier 20 is connected to sensing terminals 36, 37 and supplies two equal and opposite signals to an absolute value circuit 21 which produces a single polarity output representative of signals of either polarity at terminals 36, 37. Circuit 21 may comprise two emitter followers with common base and emitter connections. 
     In an alternative embodiment an input signal is passed through an inverting amplifier to produce an equal and opposite signal and the two signals are again applied to an absolute value circuit. 
     A reversion circuit 22 detects heart activity to produce a "sense" output, e.g. to digital pacemaker circuitry. The reduced polarity disparity enables the reversion circuit sensitivity to be easily controlled.

Abstract: A stationary engine installation comprises a gas engine (10) having a carburetor (12) and an exhaust pipe (18) supplying exhaust gas to a turbocharger (22). Combustion air is supplied to the carburetor via an air conduit (30), cooler (32), conduit (36), orifice (38) and venturi (40). An air supply conduit (50) incorporating a normally closed valve (54) connects the air conduit (30) to the exhaust pipe (18) whilst an exhaust conduit (42, 48) incorporating a cooler (44) and a normally closed valve (52) connects the exhaust pipe (18) to the venturi to recirculate exhaust gas from the exhaust pipe to the carburetor. The normally closed valves (52, 54) are opened when pressure in air conduit (36) exceeds a predetermined value so that the valves (52, 54) are both closed during start-up and idle conditions. When opened the valves (52, 54) allow recirculation of exhaust gases to reduce nitrogen oxides in the finally exhausted gas without the use of pumps or blowers.

Abstract: Ultraviolet radiation is the wavelength range between 150 and 300 nanometers, which both generates ozone (O3) and has a germicidal effect both in ambient air and in a pure oxygen atmosphere, is performed in a highly energy-efficient manner, by utilizing a low-voltage, low-pressure gas discharge lamp, by using a radiation-transparent quartz tube, by equipping it with a long-lasting sintered electrode pair and filling it with a mixture of gas vapor and mercury vapor, by disposing a circuit device between the mains and the gas discharge tube which rectifies the mains alternating current and effects smoothing voltage multiplication, and by coupling this circuit device with an automatic, dry-switching commutator device for the direct current of the gas discharge lamp, in order in principle to avoid a mercury-vapor dissociation (cataphoresis) which would reduce the effectiveness of the radiation. As a result of the direct current operation, the energy efficiency of the UV radiation generator is improved by up to 30%, as compared with direct operation of the gas discharge lamp with alternating current and a standard alternating current choke, because of the reduction in heat losses both in the gas discharge process and in the voltage multiplier choke.

Abstract: A Pd/PdO probe is used which reversibly oxidises at a defined oxygen partial pressure as a function of temperature and consequently undergoes an abrupt change in its electrical resistance. To determine the temperature at which this resistance change takes place, a resistance value is specified which is between the resistance of the oxidised probe and that of the reduced probe at least in a selected temperature range, and the temperature is set to a value at which the electrical resistance of the probe is equal to the specified resistance value. The specified resistance, optionally chosen as a function of temperature, produces a control curve which makes it possible to regulate the probe temperature reliably to the conversion temperature which is a precise measure of the oxygen partial pressure in a gas mixture flowing round the probe.
