Title: IR detector system - has detectors facing each other, with memory stages to ensure that false signals are avoided
Inventor: KUHBIER JOACHIM
IPC: G08B13/19
Filed: 1978-05-10
Abstract: An IR detector security system is designed to avoid false triggering due to environmental effects and the intrusion of small animals. Receivers (E1, E2) are located directly opposite each other within a monitored area. Each receiver has an associated memory stage (S1, S2) that switches for a period that exceeds the response time.

Title: Hardboard fibrous cake prepn. - from unclassified material dispensed from two bunkers with classification effected by spreading during levelling of cake
IPC: B27N3/14
Filed: 1978-07-28
Abstract: Hardboard cake is prepd. by passing an endless belt past two fibrous material storing and dispensing bunkers between which is disposed a compactor and depositing the unclassified fibrous material from the bunkers such that at least during the levelling of the fibrous material in the cake the material is spread by casting so that in the end result the fine and finest particles form the upper and lower layers and the coarse and coarsest particle form the intermediate central layer.

Title: Pebble bed reactor emergency shut=down and decay heat removal - by discharge of core into water filled tank esp. after other safety systems fail
Inventor: HARDER HERBERT DR
IPC: G21C1/07
Filed: 1979-11-14
Abstract: A method for the emergency shutdown and removal of decay heat of a gas-cooled, high-temp reactor (pebble bed reactor), where new spherical fuel elements are fed in at the top and irradiated elements discharged from a pipe at the bottom, is as follows. The reactor core is discharged under gravity through the fuel discharge pipe into a water-filled collecting basin located at a lower level than the reactor core. This core discharge procedure may be triggered by hand, or automatically if more conventional shutdown and heat removal systems, e.g. comprising shutdown rods, have failed. Pref, a single collecting tank, large enough to receive the entire core, is used. Used as a shutdown system of "last resort", if other more conventional systems should fail.

Title: Counting binary coded signal clock frequency - with quartz oscillator accuracy, by recursive filtering using incremental powers of two
Inventor: SCHAEFER HERMANN DIPL ING DR
IPC: G01R23/02
Filed: 1980-02-29
Abstract: A clock frequency measurement device for binary coded signals has quartz accuracy. It measures the time between successive signal edges, taking account of signal edge disturbances such as shifts, absences, dualities. The accuracy of measurement increases continuously during the measurement period. Signal intervals are collectively counted using a running clock of frequency fz. An error Dn is determined in each interval n from the counter result Zn. It is sealed with a factor k1, averaged in a digital recursive filter of feedback factor k2 and scaled again with a factor k2. The result is added to a code element duration E(n-1) which is preset to a value Eo at the start of measurement. The sum is used to improve the value obtained by dividing the frequency fz by the duration En. The constants are obtained from an incremental power of two relationship.
