Patent DE-3212529-A1 (DE)
Title: Method and device for carrying out the method for cooling frozen medical products, for example in disposable injection syringes, during dispatch
Inventor: KAETHER JUERGEN
IPC: B65D81/18
Filed: 1982-04-03
Abstract: Frozen cell preparations must not be stored at a temperature exceeding minus 70 DEG C and must be transported to the consignee at as low a temperature as possible in order to avoid autolysis (cellular decomposition). For dispatch of, for example, frozen cell preparations in disposable injection syringes in insulating containers by means of CO2 dry ice it has hitherto been necessary, in order to avoid damage to the injection syringes, 1) for the injection syringes to be packed with a cushioning and sealed in PE film bags, and 2) for the dry ice discs to be enclosed with a cushioning in separate PE film bags in the insulating container. Due to such a suppression of a flow of cold CO2 gas to, for example, the injection syringes there were considerable temperature differences (up to about 35 DEG C) within the insulating container. In the cooling method, for example, the injection syringes in the insulating container are permanently surrounded by a controlled flow of cold CO2 gas due to the special shaping of the container and due to particular precautionary measures, as a result of which the injection syringes have a considerably lower temperature throughout the dispatch. The shaping of the insulating container ensures functioning of the cooling method irrespective of the position of the container during transport and, as a result of particular precautionary measures, at the same time offers reliable protection of the fragile injection syringes against damage by the weight of the dry ice due to shocks during transport. <IMAGE>

Title: Oil/gas compression spring for working chairs, in particular for office chairs
Inventor: HANSEN ECKHARD
IPC: A47C3/30
Filed: 1982-05-21
Abstract: Oil/gas compression spring for working chairs, in particular for office chairs, for the setting, by means of locking, and at the same time springing of the seat area and backrest. What is novel is that a normal, commercially available gas compression spring lockable from the outside by means of a lever is mounted with the outside of its housing longitudinally displaceable, with the interposition of a seal, in the end face of a further housing surrounding the gas compression spring, through the other end face of which the free end of the piston rod of the gas compression spring is guided, and that the interspace between the gas compression spring and the further housing is filled with gas, for example air, which experiences a pressure increase on compression of the gas compression spring as a result of its further penetration into this interspace. A special additional feature is that, besides the compressible gas, oil is also additionally provided in this interspace.

Title: Device for suppressing interference signals in ballistic measurements using light barriers
Inventor: WOESS GERHARD DIPL ING
IPC: G01P3/68
Filed: 1982-11-06
Abstract: In a device for ballistic measurement using light areas, the interference signals which originate from the shock waves caused by the round and are of substantially shorter duration than the signals caused by the round itself are excluded by arranging that the measured signal does not come to be actually evaluated until the expiry of a reference time that is selected to be longer than the duration of the shock waves. In this case, the reference time can be determined, for example, via a solid-state oscillator or an assigned counter.

Title: Apparatus for monitoring the temperature of electrically operated apparatuses
Inventor: KRAULEIDIES HORST DIPL ING
IPC: H01H37/04
Filed: 1983-02-24
Abstract: The subject matter relates to an apparatus for monitoring the temperature of electrically operated apparatuses which are operated in continuous operation or in the standby mode. In order to prevent a fire breaking out as a result of excessive heat development in the apparatus, the monitoring apparatus which is proposed here is intended to interrupt the power supply to an electrically operated apparatus which is to be monitored. To this end, the monitoring apparatus comprises an apparatus part for holding control devices, on which an input terminal for the connection of the supply voltage and an output terminal for the connection of the load which is to be monitored are arranged, as well as a temperature sensor device which is arranged permanently connected to the apparatus part and a switch for bringing the apparatus into operation. In order to prevent faulty monitoring apparatuses being used for the monitoring tasks themselves, said monitoring apparatus can be checked by the user before use with respect to its serviceability for monitoring. This is achieved in a simple manner by the switch being constructed as a two-pole push-button switch (9) which is connected at its pole on the supply voltage side via a resistor (12) and, at its other pole on the supply voltage side via a resistor which is constructed as a PTC thermistor (13) to the input terminal (2). <IMAGE>

Patent DE-3339602-A1 (DE)
Title: Moisture sensor
Inventor: BOWMAN GEORGE EDWARD
IPC: G01N22/04
Filed: 1983-11-02
Abstract: The dielectric of a moisture sensor comprising a microwave transmission line is formed, at least partly, by the material whose moisture content is to be measured, the attenuation of the microwave energy in the transmission line being measured as a measure of the moisture content. To measure moisture in anisotropic materials, the transmission line traverses a path which is not straight and has sections of roughly equal length which extend in a multiplicity of different directions which are all arranged at equal angular distances over a quadrant of an arc. The conduction path may be formed as a meander-type sequence of quandrants of circular arcs and the waveguide expediently as a strip-type transmission line.
