Patent EP-0024316-B1 (EP)
IPC: A61N1/32
Filed: 1980-07-29
Granted: 1983-04-27
Abstract: In an exemplary embodiment, the simultaneous intensity control of the individual current circuits is to be effected while avoiding undesired intensity deviations in the current circuits such as occur because of nonuniformity of multiple potentiometers, for example. Expediently, the signal frequencies are digitally generated. According to the disclosure, in every output current circuit a transistor is connected-in, which is switched between a conducting and a nonconducting condition so that the collector output exhibits either a zero value or an operating voltage value, all switching transistors being activated on the collector side via a common control element from a single voltage source. In the through-connected state, the collector voltages of the switching transistors have the same value, respectively, which can be synchronously varied in dependence upon the setting of common control element.

Abstract: A novel internal combustion cycle and internal combustion engine operating thereon. Expansion of the hot combustion gases is controllably achieved in a primary combustion/expansion chamber (227) and a secondary expansion chamber (208) in a manner to reduce engine exhaust pressures to essentially atmospheric or below. The chambers are defined by two members (209, 200) movable with respect to each other within an engine block volume. Porting and fluid flow control is accomplished through the motion of the moving members. Embodiments include the use of a suction chamber (211) which achieves subatmospheric exhaust pressures and which, in conjunction with a pressure-pumping chamber (207), achieves a "push-pull" effect on the fluid in the engine. Unique porting of the fuel/air mixture is provided and it includes, if desired, means to vary the fuel/air ratio during the cycle. The engine of this invention exhibits performance characteristics associated with the usual four-stroke cycle engines.

Title: Saw-tooth voltage generator
IPC: H03K4/50
Filed: 1981-11-06
Granted: 1986-04-23
Abstract: The saw-tooth voltage generator is particularly intended for use as a reference and rate generator for the electric monitoring of the heating of motor vehicle. The generator has an output voltage which has an ascending edge determined by an RC element and a descent edge determined by another RC element. A control element made preferably by an operational amplifier (10) is regulated by a first capacitor (C1) and the output voltage is decoupled by another capacitor (C3) having a discharge circuit (R7). The descent curve of the output voltage may thereby be shaped freely in order to have a desired non-linear profile, which is appropriate for compensating the non-linearity of the elements of the object of the adjustment. The RC element determining the descent (C3, R7) is coupled through a diode (D2) with the first capacitor (C1) of the first RC element. Both capacitors may thereby be very rapidly charged through the resistor (R5).
