Title: Tool moulding spigot-socket and sealing ring directly - welds seal with clamping bush slot into socket
Inventor: CYRIAX WILHELM
IPC: B29C45/16
Filed: 1979-09-06
Abstract: After the injection moulding in rigid synthetic material of the actual socket end fitting for receiving the smooth spigot end of a pipe section with which it is to make a joint, the sealing ring is moulded pref. in the same tool directly into the socket end, in elastically deformable material. During the moulding of the socket end, radial passages through its wall are kept open and the material for the sealing ring is injected through these passages. Method remedies the shortcomings of existing methods of providing a sealing ring in the socket end for socket and spigot type fittings for joining pipes. The injection moulding tools used are simple and uncomplicated. There is no need for time consuming machining for the insertion of the sealing ring after the socket has been moulded and there is no possibility that the sealing ring can be omitted either accidentally or by intention. Immediately on ejection from the mould the fitting is ready for use, whilst the sealing ring cannot be displaced.

Title: Long-term gas moisture content monitoring - by measuring adsorption solid vol. change from pressure change via e.g. piezoceramic sensors
Inventor: PINK HANS DIPL CHEM DR
IPC: G01N30/00
Filed: 1979-11-16
Abstract: A method and arrangement for long-term monitoring of the moisture content of gases, esp. air, involves quantitative evaluation of chemical adsorption with the moisture as one reaction partner and a solid reaction partner, to enable moisture content to be monitored independently of visual observation. The vol. change in the solid reaction partner as a result of adsorption of the moisture is converted into an equivalent pressure change which is then measured electrically. The pressure change causes a change in the electrical resistance of graphite particles. Alternatively, a piezoceramic membrane or semiconductor pressure sensors may be used. Filters present constituents tending to hinder adsorption from entering the reaction chamber which has a gas inlet and press. measurement system at opposite ends.

Title: Injection syringe gun - with compression spring between headpiece and pressure rod
Inventor: SCHRAMM HEINRICH WILHELM
IPC: A61M5/315
Filed: 1980-08-09
Abstract: A gun for injection syringes consists of a cylindrical holder for an ampoule, with a handle and a trigger which moves a pressure rod through a pawl engaged in a toothed rack on the rod. The head piece which exerts a pressure on the ampoule is sepd. from the pressure rod by a compression spring which exerts a force greater than that required for the piston during the injection. Stops on the pressure rod and the head piece limit the possible movement of the spring. This ensures that any negative pressure due to the retraction of the syringe from a vein does not suck fluid back into the ampoule. The latter can thus be re-used repeatedly.
