Title: Expansion chamber for oil-filled cable - has diaphragm between oil gas with metered gas quantity inserted in non-gaseous form
Inventor: GOEHLICH LOTHAR ING GRAD
IPC: H02G15/26
Filed: 1979-07-20
Abstract: Expansion chambers are fitted to an oil-filled cable allowing pressure regulation to compensate for temp. variations due to load or changed environmental conditions. The gas side of the expansion chamber is sealed. To ensure that the correct quantity of gas is put into the chamber to give the required pressure compensation the gas is inserted in the non-vapour phase. The application of heat after sealing the chamber then gasifies it. For example, the gas can be inserted in liq. form, typically methyl chloride, in a heat insulated capsule which bursts when the sealed chamber is subsequently heated. Alternatively, the gas is evolved by mixing two chemicals after sealing the chamber, again by the application of heat.

Title: Measuring foaming pressure, esp. of polystyrene in mould - by balanced piston with all round clearance and lip seal at rear (J5 24.2.82)
Inventor: ERLENBACH HANS
IPC: B29C39/02
Filed: 1980-08-08
Abstract: Device for measuring the foam pressure of e.g. polystyrene in a closed mould comprises a piston pushed by air or other gas against the foaming material in the mould. A vapour flow path exists around the piston inside its casing or cylinder. The side of the piston subject to the air pressure has a lip-shaped sealing element, having an area in a specific ratio to the piston face area towards the mould. Pref., the vapour flow path is formed by a peripheral clearance of 0.1-0.3 (0.2) mm around the piston. The rear face of the piston pref. has a blind recess in which the sealing element is seated. With this arrangement, the piston is virtually frictionless and the conversion or transmission ratio to the pressure indicator exceeds unity. As the mould fills, initially vapour flows past the piston rim to both sides thus balancing the pressure. Increasing foam pressure causes the lip of the seal to press against the surrounding cylinder, after which air flows in behind the piston until the pressures are balanced.
