Double-walled container for low temp. gases - has normally rigid supports reacting elastically to peak stresses
Solar collector heat source control - has changeover valve with actuating command derived from temp. difference between collector and consumer and time source
Filter bag lattice support - can be folded flat for storage and bent to shape on site
Plastic granule additive dispenser - with slotted cylinder revolved by slow speed hydraulic motor
Heat-exchanger with parallel aluminium tubes - has tubes grouped in larger ones secured positively to housing
Inlet system for IC engine - has rotating valve admitting mixture to one cylinder at a time to ensure equal flow
Thermo-mechanical overheating protective switch - has spring element of shape retaining alloy combined with manual or automatic resetting snap action mechanism
Curable mixt. of epoxide resin, poly:ol, isocyanate and catalyst - combines easy processing with high thermal stability after cure
Plastics dowel for soft material - has hollow body with slotted nose followed by three hollow, radial, pointed edged fins
