TLDR
In this paper, the authors propose a method for feeding bulk material into a space under overpressure, wherein the bulk material (20) is fed into a chamber (10) which is pressurized to a higher pressure, preferably corresponding substantially to said overpressure.Abstract:
Method for feeding bulk material into a space under overpressure, wherein the bulk material (20) is fed into a chamber (10) which is pressurized to a higher pressure, preferably corresponding substantially to said overpressure, and the material is fed into the space from the pressurized chamber. Simultaneously with or after the material being fed into the space, the volume of the chamber is reduced to a volume which is a fractional part of the normal volume of the chamber.read more

Method for transfer of particulate solid products between zones of different pressure.
TL;DR: In this article, a sluice system based on a portioning device, which produces a sequence of uniform product portions divided by uniform particle free spaces, and then the product portions are conveyed individually through a slusice device, consisting of at least one sluICE chamber and two pressure locks of which at any time secures a pressure tight barrier between the two pressure zones, is described.

Procedure and apparatus for feeding a material into a pressurized space
TL;DR: In this article, the authors described an apparatus for feeding solid material into a pressurized space, which consisted of a feed chamber (12) communicating with the pressurised space (1) via a gate (13), a piston cylinder (8) adjoining the feed chamber and provided with an aperture (28) in its wall for the intake of solid material, and a piston (9) which consists of an inner and an outer piston (11,10), moves within the piston cylinder(8) and closes the feed-chamber tightly when in its front position.

Apparatus for transferring fuel between spaces which are at differential pressures
TL;DR: In this paper, a transfer arrangement for transferring a finely divided solid material, e.g., a combustible fuel, from one to the other space, usually from the lower pressure space into the higher pressure space, is presented.
Patent
Lock for the transport of bulk material
TL;DR: In this paper, a lock chamber is driven by a reciprocal movement in a horizontal guide tube (2), which comprises on different sides of its wall a first opening (12) leading to the chamber with lower pressure and in an axial distance therefrom a second opening (15), leading to a chamber with higher pressure, wherein the chamber comprises openings (13, 14), which can be brought in coincidence with the first and second opening at the points or reversal of the reciprocal movement.
