Title: N-path filter using switches and capacitors
Inventor: BETZL HERMANN DIPL ING
IPC: H03H19/00
Filed: 1981-08-17
Abstract: In this filter, the switches are controlled by three to N clock phases which do not overlap in time and a signal voltage is applied to the input end. It is the object of the invention to specify such filter circuits from the second degree onwards, which have predetermined transfer functions without requiring isolating amplifiers. This object is achieved in such a manner that the signal voltage (U1) is impressed on a capacitor (5) of the first path (I) in the first clock phase (1), that this capacitor (5) equalises with the first storage capacitor (C1) in the subsequent clock phase (2) and, at the same time, the signal voltage (U1) is impressed on the capacitor (6) of the second single path (II), and that the capacitor (5) is also equalised with the second storage capacitor (C2) of the first single path (I) in third clock phase (3) and the capacitor (6) of the second single path (II) is equalised with its first storage capacitor (C1) and, at the same time, the signal voltage (U1) is impressed on the capacitor (7) of the third single path (III), that this process is repeated up to the Nth clock phase, and that the in each case last storage capacitor (C3) of in each case only a single path (I, II, III,... N) is connected to the output terminal pair in a cyclic sequence during each clock phase. <IMAGE>

Patent DE-3201858-A1 (DE)
Title: Magnetic-field therapeutic device
Inventor: WEILER WALTER
IPC: A61N2/04
Filed: 1982-01-22
Abstract: This device is mainly intended for medical applications. Living beings harmed by unphysiological sound (noise) are able to regenerate with the aid of the device. For this, the device supplies the being with those electromagnetic sound waves by which it is harmed. A magnetic tape recording played back by a drive is used as the sound store. The stored vibrations are amplified and supplied electromagnetically to the person harmed by sound. This has a favourable influence on, or eliminates, communication disturbances of an electromagnetical nature (for example diseases of the body).

Title: Device for altering the valve and/or injection timings on a reciprocating-piston internal combustion engine
Inventor: HAEFNER REINHARD DIPL ING
IPC: F02D1/16
Filed: 1982-07-03
Abstract: To provide the possibility of altering the valve and injection timings on a reciprocating-piston internal combustion engine, the angle of the camshaft can be adjusted by using intermeshing helically toothed gearwheels. In this arrangement, the first helically toothed gearwheel is arranged at any desired point in the gear train between the crankshaft and the camshaft. The second helically toothed gearwheel is seated in axially secured fashion on a bearing axle which is arranged parallel to the camshaft and, in addition to the helically toothed gear wheel, carries a further gearwheel of the gear train. The bearing axle is furthermore mounted in axially displaceable fashion and is coupled to an adjusting mechanism which ensures sensitive axial displacement of the said axle with the second helically toothed gearwheel and, if required, also a further gearwheel. The bearing axle is finally also assigned a device which allows it to be locked in any desired displacement position. This overall arrangement permits angular adjustment of the camshaft by a few angular degrees.

Abstract: Es wird ein Rechner und ein System zur Integration von Software mit Hardware offenbart, das als "Integrations-Control-System - ICS" bezeichnet wird. Hierbei handelt es sich um ein automatisches Verfahren zum Formatisieren eines maschinenunabhängigen Programmschreibens in einer hochentwickelten Programmsprache, um einem Prozessor ein System zu geben, ohne daß eine genaue Kenntnis des Assemblers, der Linker-Erfordernisse oder der Sprach-Interface-Erfordernisse nötig ist. ICS gibt hierbei die Minimalerfordernisse selbst vor. Das ICS-System läßt sich in einem besonderen Speicher, zugreifbar für jede beliebige Computer-Konfiguration, ablegen. Hieraus wird automatisch der Ablauf des Integrationssystems aufgebaut. Durch Verwendung hochentwickelter Weisungen ist das Entwicklungssystem wesentlich schneller und kontrolliert sich selbst auf Fehler. Selbst Fehler, die sich sonst erst im Betrieb bemerkbar machen, werden ausgeschaltet. Es entsteht ein sofort exekutierbares Modul, das in herkömmlicher Weise abgelegt, beispielsweise in PROM, eingebrannt werden kann.
