Inventor: GEHRER EUGEN
IPC: A45C13/18
Filed: 1979-06-28
Abstract: The container has two electronic monitoring systems which are each connected to a lock (34, 35). One monitoring system is aimed against snatching away and being taken hold of, while the other system is intended to produce a strongbox function of the container. This is achieved by monitoring for forcible opening (33, 38) and for attempts to render the electronics and/or battery unusable by overtemperature or low temperature (39, 40) or immersion in fluid (41). The security measures which are triggered by the monitoring systems consist of initial warning, alarm (29) and triggering (47, 50) of a destruction mechanism. Once the security measures have been initiated, they can be interrupted immediately by means of a key (34). The operational readiness can be produced again at any time. Before the monitoring and security systems come into action, said systems can be simulated in the original without damaging the container or its contents. <IMAGE>

Patent DE-2939828-A1 (DE)
Inventor: VILLARS JEAN-CLAUDE
IPC: B05D1/30
Filed: 1979-10-01
Abstract: A rotatably mounted, driven powder-entraining roll arranged at a distance above the web is used. The cylindrical outer circumferential surface, which is provided with a multiplicity of annular grooves, of said powder-entraining roll rotates below a supply vessel containing the plastic powder and entrains powder from the vessel on its circumference. This powder is subsequently removed again from the outer circumferential surface of the powder-entraining roll. The process is characterised in that the plastic powder (2) is blown off the outer circumferential surface (52) of the powder-entraining roll (5) by an air jet which is directed towards the outer circumferential surface (52) of the powder-entraining roll (5) and the intensity of which is just sufficient to release the plastic powder (2) located in the annular grooves (54) from the latter so that it falls down under the effect of gravity onto the webs moving past below the powder-entraining roll (5). <IMAGE>

Title: Methane detected quantitatively by temp. controlled pyrolysis - which prevents full combustion and consequent falsification of carbon mon:oxide detector reading
Inventor: LEICHNITZ KURT
IPC: G01N31/22
Filed: 1980-03-29
Abstract: A method of detecting methane is ampled air by pyrolysis using small tubes is as follows. The sampled air is drawn in by a suction pump (1), firstly through a pyrolysis furnace (5) in which the methane is oxydised to CO at a predetermined, controlled temp. of 800-950 deg.C and then secondly through a cooling range (6) and a CO test tube (3). For the detecting of dangerous ignitable mixts. of CH4 in the atmos. The strict control of the temp. in the pyrolysis furnace to the range 800-950 deg.C assures incomplete combustion of the methane to CO. This is so even when the oxidn. process produces additional heat. In this way quantitative indication in the CO tube is possible.
