Title: One-pack adhesive/sealants - in tubular form with core contg hardener
IPC: B29C48/335
Filed: 1973-05-03
Abstract: The one-component system consists of a tubular jacket of >=1 unvulcanised or unhardened polymer layer, and a core contg. vulcanising agent or hardener for the polymer. Pref. an inner layer is present between outer jacket and core, and the outer jacket consists of a polysulphide polymer of mol. wt. 1000-10000 alpha a polybutadiene of mol. wt. 2000. The hardener is pref. dispersed in a liquid carrier to form a paste. The jacket is formed by extrusion and pref. filled simultaneously with hardener injected through the centre. The components are mixed together immediately before use, to form a putty-like mass which hardens on standing, suitable for sealing and adhesive purposes e.g. around windscreens in vehicles, glass panes in building, etc. Storage life before mixing is almost unlimited and mixing requires only simple and cheap equipment, without weighing of separate components.

Title: Microorganism analysis - by measuring change in electrical conductivity
IPC: G01N27/06
Filed: 1973-05-07
Abstract: Microbiological growth is determined quickly by measuring the change in electrical conductivity of a nutrient medium in an incubated closed cell inoculated with suspected micro-organism contamination. A plot of change in conductivity with time reveals a curve which is characteristic for a particular species of micro-organism in a particular nutrient medium. The selection of suitable nutrient media and the measurement of conductivity changes can give a determination of presence, type, antiserum sensitivity and a quantitative count of bacteria and other micro-organisms present in a selected sample.

Title: Layered plaster board panel - having a core and fibre reinforced outer layers
IPC: B32B5/18
Filed: 1974-11-08
Abstract: Panel of reinforced plaster comprises two opposed external surface layers with facing sheets, the layers comprising rehydrated moulding plaster reinforced with the glass fibres distributed in a selective manner in the plaster, and a central core of non reinforced moulding plaster. The outer plaster layers have a greater plaster density than the core layer so that the panel can be flexed. Each layer hs essentially a constant density. The panel is useful in building e.g. for partitions and esp. for lifts in high buildings. It has increased resistance to bending stresses due to wind pressure and will bend rather than cracking as in prior art, while having an excellent resistance to penetration by fire. It does not need cellulosic covering sheets nor does it contain combustible smoke producing elements to help it to bend under stress.

Title: Radio communication network with central station polling substations - has priority system allowing transmission from substation waiting longest to transmit
Inventor: CARDONA GILBERT ANDRE
IPC: H04Q9/00
Filed: 1976-08-17
Abstract: The radio communications system has a central station polling outstations and not only recognising when they want to transmit but also their priority. Priority is arranged according to the time an outstation has been waiting to transmit. Each outstation sends its message together with the time between release and the sending of the message. This time is measured by a counter which is coupled to an oscillator when the message is released and disconnected from it and reset when the message is sent. This reduces the waiting time.
