Title: Reducing waste from polycondensation of ethylene terephthalate - with aid of series of vacuum aggregates, pumps and vapour ejectors driven by recycled glycol vapours
Inventor: EBNER KARL
IPC: C08G63/78
Filed: 1978-03-03
Abstract: Removal of vaporous reaction prods. in mfr. of polyesters, esp. polyethylene terephthalate, as in parent patent, is effected with the aid of vacuum units connected via suction lines with the vapour chambers of the reactors. At least the first 2 stages of the vacuum units are designed as vapour ejectors driven by glycol vapour. The process also uses condensers up or downstream of the vacuum units. Final compression of any reaction prods. not condensed in the condensers dof preceding stages, and of uncondensed, entrained, gases, up to atmospheric pressure, is carried out by a ring pump installed downstream and driven by liq. glycol. In this addn., the glycol-vapour-driven condensers are mixing condensers from each of which the condensate is conveyed into an associated, separate, container. Part of that condensate is recycled, after cooling, to its respective mixing condenser to serve as coolant; whilst part of the condensate is evaporated and conveyed to the vapour ejector upstream of the associated mixing condenser, and used to drive it. The amounts of fresh glycol used to operate this process are kept at a minimum, whilst ensuring constant vacuum.

Title: Releasable electrical connector system - is formed by growing layers of dendritic crystals on metal surface and dendrites interlock to give good contact
Inventor: BABUKA ROBERT
IPC: H05K3/40
Filed: 1978-04-14
Abstract: An electrical contact device consists of a substrate having a dendritic array which is grown on it and the dendrites are adapted to releasably engage corresponding dendrites on a mating surface. A typical contact comprises a conducting base plate (11) bearing a group of elastic metallic projections (13). For this purpose a suitable base plate consists of a substrate with a coating of noble metal (15) on which the dendrite crystals are formed. A second electrical contact is similarly formed of a conducting base plate (21) with closely spaced, elastic metallic projections (23). On being brought together the dendritic crystals interlock to form a good electrical connection which can, however, be readily separated. The technique is suitable for connections to LSI integrated circuits.

Title: Safety valve for nuclear power plant - has duplicated actuator systems without spring mechanisms in second system
Inventor: GELIUS FREDRIK DIPL ING
IPC: G21C9/00
Filed: 1978-09-23
Abstract: A safety valve for a nuclear power plant is connected between a high-pressure system and a low-pressure system and is operated by a control fluid in one of two ways; the control fluid line is either connected to the upstream (high-pressure) side to open the valve or is connected to the downstream (low-pressure) side to open the valve. The connection to this high-pressure or low-pressure system is provided, in parallel, by a first valve operated either electrically or by pressurised fluid so as to open when pressure on the high-pressure side exceeds a certain limiting value and by a second valve or valves, each consisting of a bursting disc connected in series to an open cut-off valve the limiting pressure at which the first valve opens is at most 95% of the pressure required for bursting one of these valves. Used partic. for nuclear power plants with highly exacting safety requirements for their valves. The new arrangement does not involve spring-loaded pistons in its second valve system, such pistons require yearly maintenance and inspection, necessitating dismantling to adjust the spring force.
