Patent DE-3112669-A1 (DE)
Inventor: SCHMIERER KARL-HEINZ
IPC: G04F3/02
Filed: 1981-03-31
Abstract: 1. Time switch mechanism for the time-delayed triggering of a switching device, more especially for making explosive charges live, wherein the switching process is delayed by the constant rotation of an initially-tensioned toothed disc (13), which co-operates with a retard mechanism, through a predetermined angle of rotation at a predetermined angular velocity about a shaft (12) mounted in plates (10, 11) or in a plate (11) and is triggered once this angle of rotation has been traversed, wherein the toothed disc (13) has safety components associated therewith which block the toothed disc if the retard mechanism fails, characterized in that the safety elements contain a safety cam (16, 26) which is guided in guide grooves (20, 21, 27) in the plates (10, 11) or in a plate (11), said cam engaging in a carrier recess (17, 28) in the toothed disc (13) and being actuated by an external force in a substantially radial direction relative to the toothed disc (13), and in that the guide grooves (20, 21, 27) comprise a first portion, which extends substantially tangentially or in a circumferential direction relative to the toothed disc (13) over a predetermined angular portion (alpha, vtheta) of the predetermined angle of rotation (beta) and overlaps the carrier recess (17, 28) in the toothed cam, and a second portion which extends therefrom in a substantially radial direction, thereby resulting in the guide grooves (20, 21, 27) extending in a T-shaped or hook-like manner so that, during satisfactory operation, the safety cam is displaced into the radial portion of the guide grooves as a result of the external force after said cam has passed the first portion of the guide grooves (20, 21, 27) and thereby releases the toothed disc (13), whereas, in the event of a malfunction, the safety cam is securely clamped by the rapid full-rotation of the toothed disc (13) between the end of the first portion of the guide grooves and the carrier recess (17, 28) and blocks the toothed disc (13).

Title: Device for controlling the composition of the operating mixture of an internal combustion engine by varying the amount of exhaust gas recirculated
Inventor: VOGTMANN HANS-JOERG DIPL ING
IPC: F02M26/62
Filed: 1981-06-26
Abstract: Device for controlling the composition of the operating mixture of an internal combustion engine with an arbitrarily actuatable fuel metering device, having a delivery adjusting element with adjusting lever, to which device means are also assigned for varying the amount of recirculated exhaust gas fed into the intake pipe. For controlling the amount of recirculated exhaust gas and for interrupting the exhaust gas recirculation in acceleration and full load phases, a pickup in the form of an aneroid capsule is provided which, together with the adjusting lever of the fuel metering device, forms an electrical switch. In the normal or rest condition the plunger of the aneroid capsule bears on the adjusting lever; the contact thereby produced is broken, however, when the adjusting lever moves towards an increase in the fuel delivery, since a vacuum braking the following movement of the plunger (24) is hereby built up in the spring chamber of the aneroid capsule (21). For acceleration phases therefore, this results in a timed interruption of the exhaust gas recirculation, whereas at full load the exhaust gas recirculation is permanently interrupted by structural means. <IMAGE>
