Title: Operation monitoring of digital transmission systems
Inventor: BURGMEIER JUERGEN DIPL ING
IPC: H04B10/00
Filed: 1981-08-26
Abstract: It is known for information relating to the bit error rate and other parameters of the transmission system to be transmitted to an evaluating terminal station in digital transmission systems by subjecting the useful signal pulses to additional jitter and, for this purpose, by coupling a signal which causes the jitter into the phase locked loop of the signal regenerator concerned which is used for clock extraction. To enable clear distinction between the telemetry signal and the monitoring station, a control signal is also transmitted according to the invention, similarly by subjecting the useful signal pulses to jitter, following transmission of the telemetry information by the monitoring station. This control signal is transmitted at a jitter frequency which is unable to pass through the downstream intermediate regenerators, with the result that the control signal can be identified only in the immediately following intermediate regenerator and the transmission of the telemetry signal is initiated therein. The invention is intended in particular for use in regenerative optical waveguide systems. <IMAGE>

Title: Device for establishing an interruption in the cooling temperature in a cooling chain
Inventor: ARMANN HERWALD
IPC: G01K11/06
Filed: 1981-11-20
Abstract: The invention relates to a device for establishing an interruption in the cooling temperature in a cooling chain. According to the invention, temperature ranges above 0 DEG C are also to be monitored, for example temperature ranges of +5, +10, +15 and +20 DEG C. According to the invention, for this purpose the use is proposed of a liquid of a greater density in the solid state than in the liquid state, so that the volume of the liquid in the solid state is less than in the liquid state. The device comprises an inner hollow body, which is filled with the liquid and is embedded within the filling material of a hermetically sealed outer hollow body. The device is ready for operation at temperatures below the melting point of the liquid. A rise in the temperature of the device above the melting point of the liquid induces an abrupt, irreversible and consequently forgery-proof indication of an interruption in the cooling temperature in the cooling chain.

Title: Electrolysis cell for actinometers
Inventor: SUGA SHIGERU
IPC: G01N27/28
Filed: 1982-01-08
Abstract: An electrolysis cell (11) for actinometers used to measure light energy is subdivided into two regions by a partition (13). One of these regions is a glass tube (12) which leads downwards and in which the mercury thread (19) deposited during the electrolysis collects. At the bottom of the other region is mercury in which a platinum wire is immersed as anode. The cathode is composed of carbon, preferably in the form of a thin plate, and it contains a vertical cavity into which a second platinum wire is introduced. Said cavity contains mercury which connects the platinum wire electrically to the carbon. The electrolyte (21) used is a mercury iodide solution. The mercury produced during the electrolysis immediately drops off the carbon electrode in the form of fine particles and collects at the bottom of the tube (12). Since the mercury does not adhere for any time to the carbon and agglomerates to form fairly large particles, measurement with the electrolysis cell of the invention is very precise, even in the initial stage. <IMAGE>
Patent DE-3209263-A1 (DE)
Inventor: POST HANS DIPL PHYS DR
IPC: G01N24/08
Filed: 1982-03-13
Abstract: For the purpose of limiting NMR spectroscopy to a selected area of a body the said area is prepared by applying first a homogeneous magnetic field passing through the entire body and superimposing thereafter upon the said magnetic field a first magnetic field of identical orientation whose strength varies in a first sense (first field gradient), exciting thereafter all the selected nuclear spins present within the body and in addition, selectively, only the nuclear spins present in a first body plane containing the volume element and extending vertically to the said first field gradient so that the selected nuclear spins contained in this body plane are returned to the direction of the homogeneous magnetic field while the nuclear spins outside this plane receive an orientation differing from the sense of the homogeneous magnetic field. This process is repeated twice, using each time a different gradient field, so that thereafter only the nuclear spins located within the volume element selected by means of the three gradient fields are parallel to the homogeneous magnetic field and can be excited by means of one or more pulses to obtain an oscillation generating an induction signal.
