Patent DE-3906416-A1 (DE)
Title: Firing device which can be switched over for additional barrels which are mounted underneath repeater guns
Inventor: LOEFFLER ERNST
IPC: F41A19/21
Filed: 1989-03-01
Abstract: The invention is based on the object of creating a firing device, which can be switched over, in order to fire (using the existing bolt and trigger device of a repeater gun) an additional barrel which is mounted underneath and conforms with the prior Patent Application File Ref.: P 3342964.2, or similar systems. The object of the invention is achieved in that a firing bolt having a transverse screw and a return spring is mounted in the rear part of the additional barrel system, in that a breech fork (shock fork) is inserted displaceably into milled grooves on the repeater gun system, engages at the front in the transverse screw, has two lateral guard plates with spring brackets and engages at the rear, in the form of a hinge, into the limbs of a changeover rocker, and in that a sear (striking lever) is fitted to the firing bolt head of the repeater gun. In order to fire the additional barrel, the changeover rocket is raised so that the striking repeater gun firing bolt operates the firing device of the additional barrel via the sear (single-bolt system!). The sear is designed such that, during the repeater process, the firing device of the additional barrel is automatically disconnected (automatic changeover!). The firing device is particularly suitable for Mauser repeater rifles and can be produced very cost-effectively in batches.

Title: Rapidly calibrating metal oxide sensors for oxidising gas - using effusion cells, emitting gases in controlled concn.
Inventor: RUMP HANNS
IPC: G01N33/00
Filed: 1989-11-27
Abstract: Metal-oxide sensor, when heated, undergoes sensitive resistance changes in response to the presence of oxidising gases. The prolonged period needed for stabilising for the calibration of such sensors is considerably shortened by disposing near the sensor a gas effusion cell periodically induced by a control and evaluation unit emitting a defined electrical current causing emission of a defined concn. of gas, e.g. H2. The sensor element, esp. of tin oxide type, which may receive a stepped series of impulses corresp. to different concn. values, change an electrical parameter so that the control and evaluation unit pref. microprocessor controlled, can produce calibration based on two or more points. USE - Include alarm signals, esp. for fires, requiring min. power and operable for long periods. Calibration time is reduced from possible weeks to hours. The effusion cells used are readily available.

Abstract: In the appts. a first computer is provided for mean pulse frequency per time unit, detected from a pulse signal unit cycle. A decision unit for a basic pulse frequency compares the mean value of the pulse frequency from the computer with a subsequent mean pulse frequency value. The lowest mean value is temporarily stored in a memory, in which it is repeatedly renewed by a system comparing the lowest pulse frequency values of the same person with previous measurements. The comparison is carried out when the last measured lowest value is lower than the stored pulse frequency value. A second computer calculates the stress level by subtracting the lowest value of the same person, measured in the past, from the basic pulse frequency on the examination day. The stress level is displayed. ADVANTAGE - Small, lightweight, easy to use and wear.
