Patent DE-2803809-A1 (DE)
Inventor: JAEGER GERD DR SC TECHN
IPC: G01L1/24
Filed: 1978-01-28
Abstract: The device for holding and securing optical measuring elements, in particular for measuring force, consists of a plurality of plates (1.1; 1.3; 1.4) which are permanently connected to one another and in which one plate (1.1) is deformed by force as the measurand. In order to be able to utilise the measurement characteristics of the optical force-measuring elements, the holder of these elements must be configured in such a way that the plate (1.1) alone is clamped at the decisive distance from the connecting point of the plates (1.1; 1.3; 1.4). This means that spatially differing and inexactly defined contact forces do not occur at the connecting point of the plates. If the connection between the individual plates is produced by wringing, the connecting point of the plates (1.1; 1.3; 1.4) is secured by a frame (6) with a spring (7) and movable clamping jaw (8), the plate (1.1) being provided with a slot (9) on the wringing side between its holder and the connecting point. <IMAGE>

Title: Remote signal transfer circuit - consists of prim. LV circuit and sec. mains circuit influenced by external signal generator
Inventor: DETTMANN HANS-HENNING
IPC: G08B3/10
Filed: 1979-01-08
Abstract: The signal transfer circuit consists of a primary 1. v. circuit and a galvanically separated, secondary mains voltage circuit. An external signal generator momentarily effects the mains voltage so that a signal appears at each position coupled to the mains. A receiver detects these signals for the release of secondary signals. By means of a semiconductor relay, the secondary circuit can be momentarily interrupted over a complete count of 50Hz half-waves. This momentary interruption can be used to release optical or acoustic signals. The length of this interruption can be selected from one to two mains frequency half-waves. This circuit enables an optical or acoustic signal to be conveyed to selected positions, e.g. rooms of a flat, from a remote position, e.g. a front door.
