Title: Applying molten adhesives to rigid or flexible underlays - coating full width without risk of overflowing the sides
Inventor: SCHAEZLE WOLFGANG DR
IPC: B32B37/15
Filed: 1973-09-18
Abstract: Heat-melted materials, esp. molten adhesives are applied to surfaces having differing characteristics in an installation holding the molten material in a store above the nip of a stationary heated roller and a rotating drum, on the circumference of which the adhesive is carried to the receiving surface. The rotating drum which may be heated or cooled and has an outer envelope of highly polished metal or of an elastomer such as silicone rubber, is constantly covered with the molten material from the store and the transfer to the underlay takes place at a point relatively remote from the adjustable nip with the heated roller. The material being coated cannot come into proximity with the heated roller and the temp. of the adhesive can therefore be raised so as to ensure full fluidity and greater uniformity.

Title: Piston diaphragm miniature dosing pump - two in line small dia pistons are fork controlled
Inventor: ORLITA FRANZ
IPC: F04B43/067
Filed: 1975-01-08
Abstract: The bore holds a spring-loaded piston at each end, the rest position of one being fixed and the other adjustable, (it passes through the forked end of an adjustable stop and into a block behind it). When the first piston moves forward, it reduces the volume between the piston heads (displacing fluid) until it encounters the second piston, after which both move together without further change of volume/displacement of fluid. To cope with the small sizes, (the bore which may be 2mm in diameter is made parallel throughout its length, the pistons fit the bore closely for a considerable length (dispensing with gland packing) and the displaced fluid leaves the bore through an aperture in the wall. The device can be applied to pump its own fluid, or used to control the movements of a diaphragm and so pump another fluid.
