Patent DE-2911452-A1 (DE)
Title: Tamper-proof anti theft alarm - gives alarm if monitoring pulses from transmitter on object fail to arrive at receiver
Inventor: BREZINA MANFRED
IPC: G08B13/14
Filed: 1979-03-23
Abstract: A transmitter, attached to an object to be protected, sends an alarm if the object is moved. Such systems can be made tamper-proof by making the transmitter send pulses at regular intervals to a receiver, which gives the alarm if a pulse fails to arrive. If there are a number to transmitters, they are set up to send their pulses in succession so that the receiver can identify which one is missing. Being free running, the transmitters will eventually drift out of synchronism. When a permitted tolerance on the time of arrival of a pulse is exceeded, the receiver operates a malfunction alarm, calling attention to the need for re-synchronisation. The mode of transmission should be one that is blocked by an intruder, e.g. ultra-sound or infra-red, then the system will also function as an intruder alarm.

Title: Electrical assembly fault location - using light point marker involving coordinate controlled optical system with coordinate input keyboard
Inventor: CARSTENS WILHELM
IPC: G01R31/28
Filed: 1979-07-18
Abstract: Fault detection in electrical assemblies is achieved by marking each defined test point with a light point using a coordinate controlled optical system. It considerably simplifies fault location and significantly reduces the possibility of human errors. Numerical data defining the measurement points are used to control the optical system to illuminate each point which is touched by a test head. When the test head records a correct measurement value the test proceeds. When the test head records a value differing from the desired value the test procedure is interrupted and the fault fault is announced optically and/or acoustically. The test point coordinate values are input individually via the keyboard of the numerical controller.

Title: Automatic calibration of baffle plate flowmeter - using sequential compensation current measurement with fixed and moving plate
Inventor: MIRAHMADI AMIN DIPL ING
IPC: G01F25/00
Filed: 1979-10-11
Abstract: The method is for automatically calibrating a baffle plate fluid or gas flowmeter and enables the average flow speed to be measured simultaneously and independently of the density and viscosity of the medium and the resistance coefficients of the system components in the medium. The average flow speed is derived from computations combining two successively occurring measurement values. In the first step the dynamic pressure is compensated using an iron-cored electrodynamic system controller whose compensation current is stored. In the second step the baffle plate is moved through the medium at constant speed and the resulting current flowing in the electrodynamic system stored. The flow speed is then obtained from the quotient of the stored current values. The constant speed is produced using a rectangular signal converted to a triangular wave by an integrator.

Title: Increasing sensitivity of absorbing and/or fluorescent substances - using support plates with aluminium vapour deposition and silicon oxide fixation
Inventor: ECKERT THEODOR PROF DR
IPC: G01N30/92
Filed: 1979-10-19
Abstract: The sensitivity increase is intended for direct measuring of thin layer plates. The substances, separated or to be determined on the separation layers, are distributed over support olates coated with vapour deposited aluminium, fixed with transparent silicon oxide. The substances on these olates are preferably wetted with suitable substances and then covered by a non-reflecting quartz or normal glass chamber, ooen towards the separating layer side. The side wall of this chamber may be coated with a mirror layer. The process provides increased sensitivity for analysis of absorbing and/or fluorescent substances. This is attained by using the vapour deposited aluminium and the transparent silicon oxide film. A further factor of sensitivity increase is the measuring of the substances in wet condition.
